The Extent and Causes of Tax Evasion in Pakistan

The Extent and Causes of appraise Evasion in PakistanMolar and woodland (2004) investigated the efficiency of appraise through with(predicate) measure optimumity index. In their base they measured the difference between the current imposeation structure and an optimal tax structure. They employ the methodology was found on a small open economic system and they constructed an equality on economys equilibrium to construct their tax optimality index including public goods. The form used to calculate the total optimality index had four variables three private and virtuoso public good.The tax optimality index came out to be 0.7972 which showed that the taxes where 79.7% efficient comp ard to the optimal tax index. The advantages of the tax were that it immediately told how efficient where the current taxes of a field with reference to an optimal model.Kemal (2007) discussed the consequence of impedance economy and tax dodging in Pakistan. He analyzed the main causes of increase in ohmic resistance economy citing reasons such(prenominal) as intensity of regulations burden of tax and sociable transfers etc. The methodology he used was that he collected many a nonher(prenominal) micro and macro variables such as total number of confide deposits, interest rates, gross domestic product, GNP, inflation etc in aver to construct his equations to measure the extent of increase in thermionic vacuum tube economy. Years were ranging from 1973 to 2003. The equation developed was a infantile fixation equation, first legal cash is calculated, and after that velocity of capital of the United States is calculated by dividing the national income with legal money, lastly multiplying the velocity of money with illegal money gives the underground economy. Multiplying underground economy with total tax to GDP proportion gives tax dodging.Empirical results showed that some(prenominal) the size of underground economy and tax default change magnitude signifi cantly during these geezerhood. The increase was more or less predominant in 1990s. He alike think that raise in underground economy poses many line of works for policy makers. He also concluded that had there been no tax nonremittal budget balance could cause been positive.Aslam (1998) measured the size of underground economy and tax leak in Pakistan. His paper used Tanzis methodology with few changes made to the model. The range of the years was from 1960 to 1998. The modified model was of log to log specification with demand of capital assumed to me the main determinant of tax rate. The paper reinforced the mien of a large underground economy and huge tax evasion in Pakistan. Results showed the variation in underground economy is very subtle and has significant impact on GDP. Further it showed that the Dollarization of economy is major problem because of significant involvement of underground foreign exchange. The limitation of this paper was that this paper could not be concluded as completely accurate and it does not tell about a remedy plan.Jayasinghe (2007) evaluated the components and sources of tax gap in Pakistan.Presence of significant tax gap forces a country to claver higher marginal tax rates of tax payers in order to collect additional tax income required to overcome a electric potential budget deficit.The model assumes that tax evasion in the economy is delineated by a fully established hidden economy. Tax evasion is estimated through estimating the size of shadow economy through 1984-2004. A regression analysis is conducted in two specifications for comparisons. One specification is thresh by victimization total values of GDP while the other utilize per capita values for GDP.The size of the shadow economy estimated through both specifications, GDP and per capita GDP show an increasing trend. Results showed that size of underground economy has increased from 23% to 84% till 2004.Increasing trend in underground economy is follo wed by an increasing tax gap. Lastly, the paper argues that the source of declining government, revenue enhancement is growing tax gap.Hibbs and Piculescu (2005) proposed a model of how taxation and government regulations make a motion the productivity of private institution.The model proposed considers private firm with fixed capital (K) and variable labor requirements Lo, labor in official while Lu labor employed in unofficial production. Wage is identical at (w) however wage cost varies regarding the public sector, it is demand as potentially corruptible and markets for corruption would scrape giving firms opportunity for evading taxes.The model also assumes that incentive to evade taxation depend on statuary tax rates.Regression equation is developed and regression tests are run to suffer at the conclusion. Empirical results in this paper are that markets for corruption arise due to perception of figures taxes as not worth paying.Dependency on how many and to what extent f irms within a country have incentive to produce underground economy and evade taxation policies regarding taxation and consumption conditions of enforcement bureaucrats may create tradeoffs between containment of tax evasion and overall direct of economic activity.Goerke (2003) investigated the relationship between tax progressivity and the tax evasion. In this paper, the consequences of tax evasion upon employment opportunities are investigated. It relates that an increase in tax progressivity has no employment effect in the absence of evasion opportunities. The model has a fixed number of workers whose only source of income are wages (w) and who can evade income taxes a regression test is run and conclusion are drawn.The results are that employment effects more of advanced taxes in an efficiency wage economy has no employment consequences in the absence of tax evasion. The analysis has presumed a constant aim of statuary tax payments at the initial wage level.Niepelt (2003) ex plored the dynamic of tax evasion. He analyzed the dynamics of tax evasion exploitation a model in a continuous time. He developed an equation victimisation the model and his assumptions based on the households in that model.The conclusion drawn in his paper is that risk aversion and endogenous detection probability defend a central role in static theories of tax evasion. It concludes that in the presence of tax evasion, the statuary tax rate is an important policy instrument but an unpredictable indicator of the effective stance of pecuniary policy.Ahmed and Ahmed (1995) estimated the extent and level of black economy in Pakistan through financial approach. Researchers have termed the underground economy in various names such as (i) illegal economy (ii) unreported economy (iii) unrecorded economy (iv) informal economy. The method adopted for quantification of the black economy is that of Tanzi, with some modifications. The equation is of double Log specification. Tax GDP rati o sign is positive. family between interest rate on time deposits and currency ratio is said to be negative. After estimation of equations through least firm method results are obtained.It has been found that the black economy as a percentage of GDP has shown a fluctuating trend. Black economy and level of tax evasion have increased over the number of years, but black economy as a percentage of GDP has experience a decline. The sizeable magnitude loss of revenue indicates that substantial revenue can be realized by reducing the extent of tax evasion in the economy.Crane and Nourzad (1985) analyzed the effect of inflation on aggregate tax evasion in the US over the block of 1947- 81.The methodology used is to construct an equation using major termination of evasion. The major determinants are derived with the following implicit evasion function Z= f(O, f, TR, V, P). Z is a measure of tax evasion, D is probability of detection, F is fine rate, TR is tax rate, Y is real true incom e and P is inflation rate.The equation derived comes out to be a logarithmic equation in Z. the most difficult variables to quantify is dependent variable itself, Z, measuring tax evasion. Probability of detection an independent variable is measure using pitiable averages over the period of 2 years. Tax rate is calculated using weighted average marginal tax rate. Inflation is calculated using CPI.Empirical results show that aggregate income tax evasion in both absolute and relative taxes is positively related to inflation rate. Aggregate evasion is risen in absolute terms but has fallen in relative terms when real true income has risen.
