An empirical analysis of wealth taxation: equity Vs.tax compliance

Capital taxation is currently under debate, basically due to problems of administrative control and proper assessment of the levied assets. We analyze both problems focusing on a capital tax, the annual wealth tax (WT), which is only applied in five OECD countries, being Spain one of them. We concentrate our analysis on top 1% adult population, which permits us to describe the evolution of wealth concentration in Spain along 1983-2001. On average top 1% holds about 18% of total wealth, which rises to 19% when tax incompliance and under-assessment is corrected for housing, the main asset. The evolution suggests wealth concentration has risen. Regarding WT, we analyze whether it helps to reduce wealth inequality or, on the contrary, it reinforces vertical inequity (due to especial concessions) and horizontal inequity (due to the de iure and to de facto different treatment of assets). We analyze in detail housing and equity shares. By means of a time series analysis, we relate the reported values with reasonable price indicators and proxies of the propensity to save. We infer net tax compliance is extremely low, which includes both what we commonly understand by (gross) tax compliance and the degree of under-assessment due to fiscal legislation (for housing). That is especially true for housing, whose level of net tax compliance is well below 50%. Hence, we corroborate the difficulties in taxing capital, and so cast doubts on the current role of the WT in Spain in reducing wealth inequality.

Social networks and occupational choice: the endogenous formation of attitudes and beliefs about tax compliance

The paper analyses the emergence of group-specific attitudes and beliefs about tax compliance when individuals interact in a social network. It develops a model in which taxpayers possess a range of individual characteristics – including attitude to risk, potential for success in self-employment, and the weight attached to the social custom for honesty – and make an occupational choice based on these characteristics. Occupations differ in the possibility for evading tax. The social network determines which taxpayers are linked, and information about auditing and compliance is transmitted at meetings between linked taxpayers. Using agent-based simulations, the analysis demonstrates how attitudes and beliefs endogenously emerge that differ across sub-groups of the population. Compliance behaviour is different across occupational groups, and this is reinforced by the development of group-specific attitudes and beliefs. Taxpayers self-select into occupations according to the degree of risk aversion, the subjective probability of audit is sustained above the objective probability, and the weight attached to the social custom differs across occupations. These factors combine to lead to compliance levels that differ across occupations.

Influence of individual ethical orientation on tax compliance: evidence among Ghanaian taxpayers

Even though Africa has constantly emphasized the need to reduce deficit financing through mobilization of more internal revenues, this has not been achieved. Perhaps encouraging voluntary tax compliance can improve internal revenue mobilization. This study explores the relationship between ethical orientation and tax compliance and finds that ethical persons are generally more tax compliant than unethical persons but are more influenced by considerations of tax rate and withholding positions compared to unethical persons. The findings of this study differ from Reckers et al. in a number of ways and contribute to the literature by providing a possible explanation of the cause(s) of tax non- compliance.

Sales tax enforcement: An empirical analysis of compliance enforcement methodologies and pathologies

Most research on tax evasion has focused on the income tax. Sales tax evasion has been largely ignored and dismissed as immaterial. This paper explored the differences between income tax and sales tax evasion and demonstrated that sales tax enforcement is deserving of and requires the use of different tools to achieve compliance. Specifically, the major enforcement problem with sales tax is not evasion: it is theft perpetrated by companies that act as collection agents for the state. Companies engage in a principal-agent relationship with the state and many retain funds collected as an agent of the state for private use. As such, the act of sales tax theft bears more resemblance to embezzlement than to income tax evasion. It has long been assumed that the sales tax is nearly evasion free, and state revenue departments report voluntary compliance in a manner that perpetuates this myth. Current sales tax compliance enforcement methodologies are similar in form to income tax compliance enforcement methodologies and are based largely on trust. The primary focus is on delinquent filers with a very small percentage of businesses subject to audit. As a result, there is a very large group of noncompliant businesses who file on time and fly below the radar while stealing millions of taxpayer dollars. ^ The author utilized a variety of statistical methods with actual field data derived from operations of the Southern Region Criminal Investigations Unit of the Florida Department of Revenue to evaluate current and proposed sales tax compliance enforcement methodologies in a quasi-experimental, time series research design and to set forth a typology of sales tax evaders. This study showed that current estimates of voluntary compliance in sales tax systems are seriously and significantly overstated and that current enforcement methodologies are inadequate to identify the majority of violators and enforce compliance. Sales tax evasion is modeled using the theory of planned behavior and Cressey’s fraud triangle and it is demonstrated that proactive enforcement activities, characterized by substantial contact with non-delinquent taxpayers, results in superior ability to identify noncompliance and provides a structure through which noncompliant businesses can be rehabilitated.^

Taloushallinnon eettiset ongelmat verotarkastuskertomuksista tehtyjen havaintojen perusteella

Tässä tutkielmassa tutkittiin taloushallinnon eettisiä ongelmakohtia käyttäen aineistona verotarkastuskertomuksia. Tutkielman tavoitteena oli selvittää onko taloushallinnon eettisissä ratkaisuissa kyse kirjanpitäjän vai yrittäjän etiikasta, voidaanko verotarkastuksella havaitut virheet jaotella tahallisiin ja tahattomiin ja voidaanko näistä virheistä tehdä johtopäätöksiä veronmaksumyönteisyydestä. Kirjanpitäjän ja yrittäjän etiikan havaittiin ilmenevän eri tavoilla. Jos etiikkaa pohdittiin veronmaksuhalukkuuden merkityksessä, niin tällöin kyse oli yrittäjän etiikasta. Verotarkastuksilla havaitut virheet jaoteltiin virhetyyppeihin, joita käytettiin veronmaksumyönteisyyden analysointiin. Tutkielmassa käytettyjä virhetyyppejä olivat muun muassa luontois- ja henkilökuntaedut, kustannusten korvaukset ja edustusmenot. Veronmaksumyönteisyydessä havaittiin selviä eroja eri virhetyyppien välillä. Suurin osa virhetyypeistä kuului veronmaksumyönteisyyden perusteella joukkoon, jossa lakeja noudatetaan vain valvonnan alaisena. Näitä virheitä tekevien kohdalla verovalvonnan kattavuudella saavutetaan parhaat tulokset.

Applications of behavioural economics to tax evasion

The paper reviews recent models that have applied the techniques of behavioural economics to the analysis of the tax compliance choice of an individual taxpayer. The construction of these models is motivated by the failure of the Yitzhaki version of the Allingham–Sandmo model to predict correctly the proportion of taxpayers who will evade and the effect of an increase in the tax rate upon the chosen level of evasion. Recent approaches have applied non-expected utility theory to the compliance decision and have addressed social interaction. The models we describe are able to match the observed extent of evasion and correctly predict the tax effect but do not have the parsimony or precision of the Yitzhaki model.

Rakennusalan käännetty arvonlisäverovelvollisuus Suomessa - arviointi ensi hetkien kokemusten perusteella

Tutkielman tavoitteena on selvittää ja arvioida rakennusalan käännettyä arvonlisäverotusta koskevan säännöksen onnistuneisuutta ja toimivuutta siirtymävaiheen ja ensi hetkien kokemuksien perusteella. Empiirisenä aineistona käytetään Verohallinnon neuvontapuhelimeen esitettyjä kysymyksiä. Tutkielmassa käydään läpi yritysten hallinnollista taakkaa ja sen muodostumista sekä tutkitaan veronmaksumyönteisyyttä ja siihen vaikuttavia tekijöitä. Tutkielmassa esitetään rakennusteollisuus toimialana ja kerrotaan erilaisista harmaan talouden muodoista ja keinoista torjua niitä. Lopuksi rakennusalan käännettyä arvonlisäveroa tutkitaan peilaamalla sen vaikutuksia yritysten hallinnolliseen taakkaan, veronmaksumyönteisyyteen sekä arvioimalla sen tehokkuutta harmaan talouden torjunnassa ja vaikutuksia verokertymään. Rakennusala on erittäin ongelmallinen harmaan talouden suhteen. Uusimpana keinona rakennusalalla harmaan talouden torjunnassa on otettu käyttöön rakennusalan käännetty arvonlisäverovelvollisuus. Säännös lisännee verokertymää ja ehkäisee tehokkaasti sellaista veronkiertoa, jossa ostaja vähentää arvonlisäveron, jonka myyjä jättää maksamatta valtiolle. Säännös saattaa lisätä myös alan veronmaksumyönteisyyttä, jos tulkinnallisia ongelmia pystytään esimerkiksi ohjeistuksen avulla vähentämään tehokkaasti. Säännös lisää yritysten hallinnollista taakka ja lisäkuormitus korostuu etenkin pk-yritysten taloushallinnossa. Useat rajanvedot eri tilanteisiin niin rakentamispalvelun määrittämisen kuin niin sanotun ostajan statuksen suhteen ovat toistaiseksi hyvin tulkinnallisia ja vaikeita ratkaista. Jos Verohallinto onnistuu ohjeistuksensa tai muiden toimiensa avulla vähentämään säännöksen aiheuttamia tulkinnallisia ongelmia, voidaan säännöksen ajatella olevan kokonaisuudessaan suhteellisen onnistunut ja toimiva sekä toteuttavan niitä tavoitteita, joita siltä odotettiinkin, eli kasvattavan verokertymää ja ehkäisevän tietynlaista harmaata taloutta.
