		Property Taxation is one of the key topics on the agenda of 
		FIG-Commission 9 for the next years. Commission Chair Francis Plimmer 
		and William Mc Cluskey (both from the UK) are discussing sustainability 
		in the context of property taxation. They consider that sustainability 
		in property taxation should be considered from three perspectives – the 
		sustainability of the tax object (land and buildings), the 
		sustainability of the tax system itself and the sustainability of the 
		uses to which the yield from property taxation are put. This paper was 
		successfully peer reviewed and presented at the FIG Working Week in 
		Marrakech May 2011.
		
		
		Key words: Sustainability; Property Taxation 
		SUMMARY 
		This paper discusses sustainability in the context of property 
		taxation. It opines that sustainability in property taxation should be 
		considered from three perspectives – the sustainability of the tax 
		object (land and buildings); the sustainability of the tax system 
		itself; and the sustainability of the uses to which the yield from 
		property taxation are put. 
		We argue that achieving concepts of sustainability within each of 
		these aspects of property taxation is important to developing a virtuous 
		circle within the property tax itself, where the property tax yield 
		enhances the value of the taxed object and thus the assessment, which in 
		turn ensures increased revenue to be spent on improving public services. 
		In this way, a sustainable property tax has the potential to make a 
		significant and positive contribution towards achieving sustainable 
		communities. 
		The paper demonstrates examples of both unsustainable and sustainable 
		practices from various jurisdictions, and makes recommendations to 
		improve sustainable outcomes where appropriate. The paper also reviews 
		the positive characteristics of property taxation and reflects on these 
		within a sustainable context. 
		The paper concludes with the view that, given the ubiquitous and 
		fundamental nature of property taxation to the ‘wealth’, well-being and 
		life-style of the vast majority of people and to the provision of ‘front 
		line’ services to local communities, these three aspects of 
		sustainability for property taxation should be goals to be discussed by 
		policy makers and all relevant stakeholders, and recognised as desirable 
		outcomes to be achieved, because of their vital importance to the 
		creation and development of sustainable communities and real estate 
		resources world-wide. 
		1. INTRODUCTION 
		For surveyors, sustainability is an increasingly important concept. 
		For those of us who are responsible for the unique and finite resources 
		of land, water and other natural assets, we have a huge responsibility 
		to ensure that such unique resources are managed in a sustainable 
		fashion for the future of humanity. 
		For those surveyors responsible for our built environment, the 
		responsibility is no less. Given the costs (environmental, financial, 
		and social) of creating buildings and other structures, ensuring that 
		they are built, managed, used and reused in a sustainable fashion, is 
		also a vital responsibility of surveyors. We need to ensure that those 
		accountable for such assets - owners and occupiers - are aware of the 
		huge importance of energy efficiency, waste management, and the health 
		and safety of users of the buildings; and to ensure that they have the 
		best tools and advice available to do their part in achieving an 
		increasingly sustainable environment for us and for future generations.
		
		Surveyors are, therefore, no strangers to sustainability. We have 
		recognised, enhanced and promoted the principles of sustainable 
		development for decades (refer for example, FIG 1991); we have moved on 
		to sustainable investment (e.g. Plimmer 2009); indeed, given our 
		responsibility for the natural and built resources of the world, it 
		could be argued that there is no aspect of our work which does not 
		impact on their future sustainability. 
		Sustainability implies both current and future economic, 
		environmental and social aspects and property taxes have all of these, 
		which are underpinned by a political dimension. Property taxes usually 
		fund services which are provided at a local level and which directly 
		affect the quality of the physical and economic environment and thus the 
		social life of communities. We therefore believe that it should be 
		possible to define and to develop property taxes which achieve 
		sustainable outcomes for each jurisdiction. 
		This paper, therefore, discusses potential characteristics of 
		sustainability in property taxation – not perhaps a topic which many 
		people would associate with sustainability. However, as with real estate 
		development and investment, sustainability has great relevance to 
		property taxation, in a number of ways, a significant one of which, we 
		opine, relates to its potential to support a sustainable society. 
		The United Nations defines a sustainable society as being one which: 
		‘meets the needs of the present without sacrificing the ability of 
		future generations to meet their own needs.’ (FIG, 2001: 19). 
		Property taxation therefore has a clear role to ensure that it is 
		established and operated in such a way that it maintains, if not 
		enhances, the physical, social and economic environment for the benefit 
		of current as well as future generations. 
		This paper reflects on how property taxation can contribute to a 
		sustainable society and in that way, achieve the status of a sustainable 
		property tax. We discuss sustainability in the context of property 
		taxation in three ways: by looking at how property taxation can affect 
		the sustainability of the objects (land and / or buildings) which are 
		taxed; the sustainability of the tax itself (i.e. its appropriateness or 
		otherwise for effective and efficient usage); and the contribution which 
		the yield from property taxation can achieve towards the sustainability 
		of communities and their built environment. 
		The paper is structured thus: Section 2 reflects on the 
		sustainability of taxable objects largely by providing evidence from 
		selected jurisdictions as to how property taxation can enhance and 
		undermine the sustainability of property, the physical property itself 
		or the use(s) to which it is put. Section 3 looks at the nature of the 
		property tax itself and how aspects of sustainability can be 
		incorporated and developed into what is already recognised as a ‘near 
		perfect’ tax. Section 3 considers how the spend from property taxes can 
		achieve sustainable outcomes within the community from which the tax is 
		levied, by reflecting on the nature of services which add value both to 
		individual (taxable) properties as well as to the wider life of the 
		community, and thus its sustainability. Finally, Section 5 offers some 
		conclusions. 
		2. THE SUSTAINABILITY OF TAXABLE OBJECTS 
		2.1 Introduction 
		Taxation is a well known government strategy for influencing 
		behaviour (as well as raising revenue) and the use of property taxes to 
		such an end is a common strategy. Thus, the way a property tax is 
		structured and implemented, can have deliberate as well as unforeseen 
		consequences for how people use their land and / or their buildings. In 
		any event, property taxes should be considered in the light of how they 
		affect the sustainability of how the taxed (and the untaxed) land and 
		buildings are used and valued by the taxpayers, as a result, as well as 
		their wider impact on society. 
		This section provides a range of examples of how different 
		characteristics of property taxes affect the sustainability of real 
		estate – the taxable object – as well as their wider market and 
		community impacts. There is discussion on how sustainable such outcomes 
		are within what is increasingly recognised as the desirable attributes 
		of sustainable communities. 
		2.1.1 Land Value Taxation 
		Land value taxation (LVT) seeks to encourage the optimum use of land 
		by taxing the land assuming that it is a cleared site available for use 
		at its highest and best use, in accordance with the prevailing planning 
		policies. One of the stated aims of LVT is ‘fashioning or promoting land 
		policy’ (Lichfield and Connellan (2000: 33). It is recognised (ibid.) 
		that ‘LVT on the basis of ‘highest and best’ use will encourage 
		development at the right time in the right place by, for instance, 
		penalizing owners of vacant sites that were being withheld from the 
		market for speculative reasons.’ 
		Therefore, LVT can be regarded as ‘sustainable’ because it 
		encourages, through the tax system, the most advantageous use of land; 
		(although perhaps it is truer to say that LVT discourages a less than 
		optimal use of land). 
		Thus, it is within its focus on encouraging the optimal use of 
		already developed land (which is generally what is covered by local 
		planning authority development plans) that LVT really earns its 
		sustainability credentials. For example, it promotes the reuse of 
		previously developed but underused land (in particular derelict and 
		vacant sites), discourages inappropriate structures and uses in 
		locations which should be attracting more valuable and more suitable 
		uses etc.; and encourages the intensification of the use of existing 
		infrastructure rather than putting pressure on developing additional 
		transport etc. resources. (see for example Connellan 2004; Almy et al., 
		2008: 186; McClean, 2006; McCluskey and Franzsen, 2005) 
		In these and in other papers on LVT, there is rarely any recognition 
		of the inherently unsustainable nature of the constant pressure which 
		LVT is designed to exert on the redevelopment of land. Yes, it is true 
		that it must be better to redevelop underused or vacant inner city 
		sites, and therefore both relieve the pressure on the development of 
		greenfield sites, as well as to optimize the use of existing 
		infrastructure which urban redevelopment implies. 
		However, the process of demolition and construction is well known for 
		generating high levels of waste (see, for example, BRE 2006) and carbon 
		emissions and for the further depletion of our finite natural resources. 
		Thus, to use the tax system to put pressure on owners to keep ensuring 
		that their existing use matches that required by their local planning 
		authority through an LVT system could be said to be environmentally 
		unsustainable, while it may be good for employment in the construction 
		industry. 
		Of course, given that it is planning policy which drives highest and 
		best use and therefore the pressure to redevelop, a different approach 
		to planning, one which reflects the need to have greater use out of 
		existing buildings, and which encouraging reuse and refurbishment rather 
		than demolition and rebuild, as well as encourages more flexibility to 
		be designed into new buildings, may be seen as an acceptable way to get 
		a higher level of long term use and therefore sustainability from 
		buildings, within an LVT. 
		2.1.2 Changing the tax base 
		‘Fairness’ and equity are generally recognised as essential elements 
		in a property tax. However, ‘fairness’ is a highly subjective concept 
		and is likely to vary given the divergent view points of different 
		stakeholders. For example, it is usually accepted that properties with 
		similar attributes in similar locations should have the same taxable 
		values (horizontal equity); so that their taxpayers are paying similar 
		sums to enjoy substantially the same amenities. This is normally 
		interpreted as ensuring that properties with similar market values have 
		similar tax assessments and therefore similar tax liabilities. 
		In California in 1978 a ‘taxpayer revolt’ secured a shift from market 
		value to acquisition value as the tax base for dwellings. The assessed 
		value is, therefore, fixed at the purchase price of the property (plus 
		2% per annum for inflation). Thus, one taxpayer who purchased a dwelling 
		in, say, 1980, could be paying tax based on its purchase price (value) 
		at that time, while a neighbour who purchased an identical property last 
		year, would be paying tax based on last year’s purchase price – and thus 
		significantly more. 
		The taxpayer revolt was triggered by a scandal involving tax 
		assessors. At a time when confidence in assessors was low, an 
		acquisition cost base was preferred because it removes any subjectivity 
		from the assessed value and can, therefore, be seen as a more accurate 
		and objective taxable figure. ‘… no assessor, not even one given 
		unlimited resources, could produce an assessment roll in which the 
		appraisal of property was strictly current and precisely accurate in all 
		respects.’ (California Taxpayers’ Association, 1993, citing The State 
		Board of Equalization, prior to the introduction of Proposition 13) 
		This acquisition value basis, the so-called Proposition 13, has been 
		adjudged ‘fairer’ by the State judiciary because such a tax base 
		encourages owner occupiers not to sell their property (and thereby lose 
		the attractive level of tax payable) and this contributes to 
		neighbourhood preservation, continuity and stability which, it is 
		argued, are highly desirable and sustainable outcomes (for example, 
		Beaumont, 1994; Picker, 2005). Such a tax base also provides a high 
		degree of predictability over next year’s tax bill. Research (Beaumont, 
		1994: 8) shows that acquisition value is perceived as more progressive 
		than an ad valorem base and that the elderly and low income groups have 
		benefited most from the change – also a useful and, it can be argued, 
		sustainable outcome. 
		Beaumont (1994: 4) provides a further justification by citing from 
		the case of Amador Valley Joint Union High School v. State Board of 
		Equalization (1978: 251) thus: 
		‘[Proposition 13] does not unduly discriminate against persons who 
		acquired their property after 1975, for those persons are assessed and 
		taxed in precisely the same matter as those who purchased in 1975, 
		namely, on an acquisition value basis predicted on the owner’s free and 
		voluntary acts of purchase.’ 
		It is argued (in California Taxpayers Association, 1993) that 
		‘California homebuyers probably pay no real tax penalty under 
		Proposition 13 because the differential assessments are capitalized into 
		the purchase price.’ However on the sale of a dwelling, any ‘reserve 
		value’ has to be built up again on the purchase and subsequent 
		occupation of a new dwelling. This has had a negative impact on the 
		property market. 
		However, the inevitable outcome of Proposition 13 was a severe loss 
		of revenue the spending authorities, as well as a loss of horizontal and 
		vertical equity (Beaumont, 1994). There is also evidence (Beaumont, 
		1994: 10) of owners investing in their homes when compared to other 
		kinds of capital investment opportunities. There is also fewer (and 
		insufficient) new dwellings being constructed and the encouragement in 
		the tax system for owners not to sell, means that the costs of 
		purchasing residential property are particularly high and that market is 
		inefficient in redistributing the supply in relation to the changing 
		demands for dwellings, with younger homeowners and newer businesses 
		disadvantaged. 
		There has also been a significant reduction in yield from the 
		property tax, which has forced municipalities to rely more heavily on 
		other forms of income (e.g. the local sales tax) and also to be 
		innovative and imaginative with other opportunities to raise revenue 
		using fees and charges for services (specifically non-tax sources). 
		According to Beaumont (1994: 13) such charges and fees ‘…have positive 
		characteristics in their revenue potential and efficiency in resource 
		allocation.’ 
		However, it has resulted in municipalities competing against each 
		other to encourage commercial taxpayers within their jurisdiction 
		(Proposition 13 only applies to residential property). As Beaumont 
		(1994: 10) says: ‘California is over-malled.’ 
		Proposition 13 has also ‘seriously damaged local democracy by 
		depriving local elected officials of basic budget responsibilities and 
		accountability.’ (Lochhead, 2003), as well as damaging the services 
		which normally receive significant funding from local property tax 
		revenues. 
		2.1.3 Exemptions and reliefs 
		Exemptions and reliefs allowed by legislation also affect the way 
		people use their property and any such concessions made, should ensure 
		sustainable outcomes. 
		In order to achieve an adequate revenue base, (which is an important 
		factor both for equity and for yield – refer, for example Lyons, 2007: 
		6.31), and to achieve the maximum participation of potential taxpayers 
		in the jurisdiction, exemptions and reliefs should be kept to a minimum.
		
		It is also argued that any exemption or relief from the tax burden 
		should be made within so-called sunset reliefs i.e. reliefs which are 
		granted for a limited period of time e.g. five years, and which are 
		reviewed at the end of the term to establish if circumstances continue 
		to justify the concession (refer IAAO, 2010: 18 – 19. This prevents 
		those who benefit from such a tax relief as viewing it ‘as of right’, 
		thus making it politically and socially harder to remove the relief when 
		it can no longer be justified. 
		However, this is not always the case. For example, in Britain, where 
		the Council Tax is imposed on domestic property, a relief of 25% of 
		taxes payable can be secured if the dwelling is occupied by only one 
		(taxable) person. 
		Such a concession is a very tangible reward (often significant in 
		monetary terms) which encourages single occupiers of large dwellings to 
		remain in place. By doing so, the concession reduces the pressure to 
		‘down size’ residential accommodation, thus denying families who need 
		such accommodation the opportunity to buy and making full use of such 
		property. This adversely affects the efficiency of the market to 
		redistribute supply, as well as also putting pressure on the housing 
		industry to provide more large homes to meet demand, with all the 
		unsustainable consequences of further development indicated above. 
		Sustainability principles would, we suggest, seek to ensure that 
		dwellings (indeed all property) are fully used, and thus, instead of 
		encouraging a single occupation, Council Tax reliefs should be reversed 
		to specifically discourage anything other than optimum use (and 
		therefore the sustainability) of property
		2.1.4 Taxing owners of empty properties 
		From 2008, owners of empty non-domestic property in the England and 
		Wales, are required to pay the same level of business rates as an 
		occupier , despite the fact that the property market is increasingly 
		depressed as a result of the current economic climate. The original 
		driver for this legislation was the concern that a number of owners were 
		deliberately keeping their premises vacant for speculative reasons, at a 
		time of rising prices and great market demand. The government’s aims for 
		this legislation also include reducing rental levels, improving the 
		efficiency and attractiveness of the British property market and to 
		encourage the reuse and redevelopment of premises (CLG, 2007: 5). 
		However, research (Plimmer, 2010) demonstrates that instead the 
		policy has resulted in increased ‘constructive vandalism’ (demolitions 
		and the stripping of services from the building, which effectively 
		removes the building from the tax liability), short-lets at nominal 
		rents (which reduce the value of the investment), and a halt on 
		development and regeneration, unless a tenant occupier can be secured in 
		advance. 
		According to Shaw (2010: 49 in Plimmer, 2010: 9): 
		‘Through raising the opportunity costs of holding vacant property, 
		supply increased as landlords made vacant property available to rent and 
		buy, however further vacancies flooded the market due to the change in 
		the economic crisis, as firms down sized and others went into 
		liquidation, increasing supply further.’ 
		By taxing owners of empty non-domestic premises, the British 
		government is acknowledging that owners of such premises benefit from 
		the services provided by the local authorities e.g. street lighting, 
		police and fire protection. However, it is the requirement to pay full 
		rates at a time of severe economic recession which is having devastating 
		effects on the commercial business sectors, with a lack of tenant demand 
		and increased voids, thus putting additional pressure to demolish 
		property which earns no income but costs a great deal to hold. 
		As Keeves (2009:4 in Plimmer, 2010: 6) says: ‘[t]he timing of this 
		legislation has proved very controversial because of the additional 
		financial pressure the government is exerting on the commercial property 
		market during a time of recession.’ While it may not be possible to 
		entangle the damaging effects of the recession from those of the new 
		empty property rate legislation, the change in the tax regime has been 
		described as the ‘killer blow’ (Plimmer, 2010: 18). 
		2.2 Sustainability of the tax object 
		The oft quoted (at least in property taxation circles) words of 
		Jean-Baptiste Colbert, who was the Finance Minister to Louise XIV: ‘The 
		art of taxation consists in so plucking the goose as to obtain the 
		largest possible amount of feathers with the smallest possible amount of 
		hissing.’ 
		As McCluskey and Plimmer (2010: 26) point out: 
		‘Continuing the metaphor, it is important that the ‘goose’ stays 
		healthy and ideally improves in health so that the quantity of the 
		‘feathers’ increases year by year. Thus, it can be argued that an 
		active, transparent and healthy property market, where local services 
		contribute to the value of taxable properties, and thereby maintain or 
		improve the value of the taxable real estate, is vital. It is certainly 
		important to ensure that the process does not damage the ‘goose’. … It 
		is also important that the process is not so painful to the ‘goose’ that 
		it bites the person plucking the feathers.’ 
		We therefore argue that, in order to be sustainable, a property tax 
		should contribute positively to the taxable value of the land and 
		buildings and encourage the optimum use, maintenance and improvements of 
		land and buildings. 
		3. THE SUSTAINABILITY OF A PROPERTY TAX 
		3.1 Characteristics of a ‘good’ tax 
		Property tax is well recognised as having a number of basic and 
		positive characteristics. Thus, because a property tax is clearly 
		related to the value on land and buildings, it has a strong locational 
		dimension and therefore an inherent link between that which is taxed, 
		those who pay, those who spend and, assuming that the money is paid to 
		provide services for local community, what the services the revenue 
		provides. 
		There is a clear and demonstrable link between what is paid and what 
		is received by the way of services, because the revenue raised within a 
		local community is spent in that community. It therefore reflects and 
		enhances the stake which residents have in their community, its 
		prosperity and lifestyle, which impact on the desirability (value) (or 
		otherwise) of property in that area (Lyons, 2007: s.138) 
		Property (land and buildings) is a very definite sign of ‘wealth’, 
		easy to value and therefore a legitimate target for taxation. As a 
		source of investment, it represents one of a number of targets for funds 
		and therefore its taxation is necessary for a balanced tax system 
		(Muellbauer, 2005; IAAO, 2010: 7) 
		A property tax is hard to evade because land and buildings are 
		visible, does not move jurisdictions and is difficult to hide. Given 
		that the level of the property tax is generally set at the level of 
		local government, there is a strong link between those who pay and those 
		who vote for local representatives, allowing for public accountability 
		of the tax setting and spending process. 
		There are copious sources which discuss what is a ‘good’ property tax 
		(for example, Almy et al., 2008; Bird and Slack, 2004; Youngman and 
		Malme, 1994), although few if any, recognise explicitly the potential 
		for its sustainability. Thus a property tax has the potential to provide 
		the following positive characteristics: 
		
			- assessments are normally available for public scrutiny and 
			therefore the amount paid is transparent and open which encourages 
			high levels of collection;
 
			- challenge against the assessment is normally available at 
			reasonably cheap, swift and informal manner, thus enabling taxpayers 
			to be satisfied that they are being equitably treated within the 
			law;
 
			- the assessment is less susceptible to fluctuations from 
			short-term economic trends and thus provides a stable, reliable and 
			predictable revenue source;
 
			- the local level of administration of the tax is effective and 
			efficient in both financial terms, timing, as well as the use of 
			(human and technical) resources, particularly when assisted by 
			modern technologies;
 
			- it is almost always exclusive to local government and therefore 
			administered locally, which allows for local variations to meet the 
			needs of the local citizens;
 
			- it promotes local autonomy and local democratic accountability;
 
			- the data required to administer the tax (including that needed 
			for assessments) can be cheap and easy to collect, store and 
			maintain, including ensuring appropriate levels of taxpayer privacy;
 
			- the legislative provisions can be comprehensive, clear, 
			requiring minimal judicial interpretation and expensive legal 
			argument to secure clarification. It should be possible to make 
			changes to such legislation promptly and efficiently to reflect any 
			necessary alterations in response to changing circumstances, and in 
			order to improve the sustainability of the tax; 
 
			- it spreads the costs of government by reaching sectors of the 
			community which might not otherwise contribute;
 
			- it involves minimal intrusion into the privacy of the taxpayer 
			and taxpayer affairs;
 
			- when subject to regular and frequent revaluations, assessments 
			can keep pace with rising incomes, costs, inflation and new 
			developments, this achieving buoyancy or income elasticity; and
 
			- it is easy to collect, allowing a range of payment methods and 
			enforcement measures. 
 
		
		Land and buildings represent a large capital investment and, for many 
		people, it is the single largest financial investment they ever make, 
		and in many jurisdictions, land and buildings represent pension rights – 
		either held personally or corporately. However, it is clear that tax is 
		paid out of income not capital and therefore the ‘fairness’ of a tax on 
		capital has been raised. Recognising this, the IAAO (2010: 7) states:
		
		‘ … one has only to note the availability of loans that use property 
		or equity in property as collateral to recognise the link to wealth and 
		ultimately to income still exists. … exemptions, circuit breakers, tax 
		abatements, classification, tax and value limitation measures, frequent 
		and regular reappraisal, and public relations have been used to 
		alleviate the real and perceived public concern with the property tax.’
		
		Thus, while ability to pay is often presented as a major disadvantage 
		to a property tax, there are opportunities within the tax system to 
		build in safeguards to protect the most vulnerable and alleviate 
		hardship. 
		After all, as a species, we need land and buildings for our survival 
		- to live, work, play and for all of the other activities in which we 
		are involved or which we require for our shelter, comfort and 
		well-being. We have no alternative commodity – property taxes are, 
		therefore, levied on a necessity of life - indeed, it is this very fact 
		which makes it all the more important to achieve the benefits of ‘value’ 
		and sustainability within the property tax. 
		3.2 Sustainable characteristics of a property tax 
		Just because characteristics of the property tax can be identified in 
		theory, does not mean that all property taxes exhibit any or all of 
		these characteristics. Indeed, many do not. Nor should it be assumed 
		that such characteristics are inherently ‘sustainable’. Each should be 
		investigated to establish how it contributes to the perceptions of 
		sustainability recognised and valued by the community. 
		Thus the sustainability of the specific variant of the property tax 
		implemented in each jurisdiction should be investigated to ensure that, 
		as far as is possible, its characteristics achieve the highest degree of 
		sustainability for the community. 
		4. THE SUSTAINABILITY OF THE USES TO WHICH THE YIELD FROM PROPERTY 
		TAX ARE PUT 
		4.1 Introduction 
		The output of the property tax should also have a sustainability 
		aspect and this means that the property tax should yield sufficient 
		revenue to provide funds for all of the necessary services at an 
		adequate level, for which the taxing authority (assumed here to be 
		municipalities) is responsible – the adequacy of the level of services 
		to be determined by the citizens who are also taxpayers. This means, of 
		course, that one aspect of the sustainability of the property tax 
		relates to the number, nature and quality of the services it is expected 
		to fund and the needs of the community. 
		In addition, it is also important for its sustainability credentials 
		that the yield should be spent on achieving sustainable outcomes for the 
		community. It is usual for the property tax to fund municipal services 
		and it is in this context that we discuss the provision funded by the 
		property tax. 
		Given that the source of the funding is the value (or some surrogate) 
		of real estate and (in the spirit of ‘geese’ and ‘hissing’ mentioned in 
		2.2 above), it must be anticipated that a significant achievement of the 
		tax yield should be the maintenance and potentially the improvement of 
		the value or attraction of the land and buildings. By adding value to 
		land and buildings (the taxable objects) through service provision, the 
		basis on which the tax is levied is enhanced, buoyancy of yield results, 
		and as does the desirability of attributes of the location. In this way 
		the property tax takes a cyclical form, a virtuous circle, of benefits 
		to both individual and community assets and lifestyles. 
		Thus, property taxation should fund services which help to achieve 
		and maintain the value and thus the sustainability of land and buildings 
		and also of their communities. Services which enhance the 
		characteristics of the local community and therefore the individual and 
		collective value of the built environment should be prioritized. 
		These might include the effective and efficient recycling and 
		composting (whether at doorsteps or at convenient central points) and 
		which minimise waste collection and disposal as well as pressure on land 
		fill sites, social services to support the vulnerable (such as the 
		elderly) as well as community education, personal improvement and advice 
		services to citizens regarding, for example, how individuals can become 
		involved in improving aspects of the community. Financial resources 
		might also be extended to the funding of improvements to buildings e.g. 
		to improve energy efficiency. 
		5. CONCLUSIONS 
		If longevity is a characteristic of sustainability, then taxing 
		property is a very sustainable way of raising tax revenue. Property 
		taxes have been around for over 7,000 years (Carlson, 2005). However, we 
		do not believe that mere survival, while an important characteristic, is 
		enough on its own to qualify the property tax as ‘sustainable’. 
		There is no such thing as a generic property tax. Taxation of 
		property (land and buildings) may exist in every country in the world, 
		but there is a huge variety of such tax systems, including different tax 
		bases, different exemptions and reliefs, and different administrative 
		and assessment systems. One size does not fit all nor should it. Given 
		its inherent local nature, each tax system should serve the needs of the 
		community and be developed, reformed and implemented accordingly. Yet it 
		is important that property taxes are in themselves sustainable and 
		contribute as much as possible to the wider sustainability of 
		communities. 
		Because each jurisdiction develops, reforms and implements their own 
		version of the tax, sustainable outcomes therefore are likely to vary 
		across jurisdictions in the way the tax has developed and how it 
		interacts with both the taxable objects and the services which it funds. 
		Indeed, different communities may prioritise different sustainable 
		outcomes according to their needs, aspirations, resources, traditions 
		and culture. 
		Thus, to achieve the optimum benefits from sustainable property 
		taxes, each jurisdiction should investigate its own sustainable 
		objectives and, in that light, achieve an appropriate variant of the 
		property tax to ensure that it contributes and is seen to contribute to 
		the overall sustainability of communities. 
		Given the range of variation of property taxes, it must be also be 
		important for policy makers to investigate and reflect on systems which 
		operate elsewhere to see if there are lessons to be learned from 
		international experience, reflecting on the how property taxes can be 
		enhances in their contribution to the three areas of sustainability 
		which we have identified here: 
		
			- sustainability of taxable objects;
 
			- sustainability of the property tax itself; and
 
			- sustainability of the uses to which the yield from the tax is 
			put. 
 
		
		It is not our intention in this paper to provide a definitive 
		definition of ‘sustainability’ in the context of property tax. Clearly, 
		a property tax must be suitable for the economic, political and social 
		environment in which it is to operate. It may be that a sustainable 
		property tax is one which is established and operated in such a way that 
		it maintains, if not enhances, the local physical, social and economic 
		environment for the benefit of current as well as future generations, 
		and thereby contributes to a sustainable community. 
		We recognise that different jurisdictions will have different views 
		of and needs from a sustainable property tax, so it is vital that they 
		each discuss and agree their requirements in the light of their 
		individual circumstances, existing and future ambitions, as well as 
		their perceptions of sustainable communities. 
		This paper contributes to the discussion about the future of property 
		taxation by identifying three significant aspects of how its 
		sustainability might be assessed. We look forward to contributing 
		further to a developing debate on this subject in the future.
