Earlier this month, parliament passed a new Inland Revenue Act, effective from April 1, 2018. How will the new tax regime affect the tax revenue and what will be the tax burden on Sri Lankan citizens? Is it more pro-poor? This article tries to answer these questions, using the results of a recent study done by the Institute of Policy Studies of Sri Lanka (IPS), in collaboration with the World Bank.  


The direct taxes paid by the people include personal income tax (PIT), pay-as-you-earn (PAYE) tax, corporate income tax and tax on interests earned. However, the article concentrates only on PIT and PAYE taxes. As stipulated in the Inland Revenue Act No. 10 of 2006, the PAYE taxes are deducted by the employers from the employees at the time of payment of their salaries and wages. The personal income tax is collected by the Inland Revenue Department on the profits and income of every person or partnership, under the Inland Revenue Act No. 10 of 2006 and its subsequent amendments.


What were income tax changes that came about with new tax bill?


The annual tax-free threshold for PAYE tax in the current tax regime is Rs.750,000. The new tax regime will increase this threshold to Rs.1,200,000. Thus, under the current tax regime, anyone earning more than Rs.62,500 a month is obliged to pay the PAYE taxes. But, according to the new tax regime, only those earning a monthly wage of Rs.100,000 or more are subject to the PAYE taxes. 
PAYE is taxed on an incremental basis. Under the current tax regime, the first Rs.750,000 is tax free, the next Rs.500,000 is taxed at 4 percent and every subsequent Rs.500,000 earned is taxed at 8 percent and 12 percent, till a maximum tax rate of 16 percent (Figure 1) is reached. With the new tax regime, the first Rs.1,200,000 is tax exempt and every subsequent Rs.600,000 earned is taxed incrementally at 4 percent, 8 percent, 12 percent, 16 percent, 20 percent, up to a maximum of 24 percent. 


In terms of the personal income tax (PIT), the annual tax-free threshold of Rs.500,000 does not change with the new tax regime. However, as with the PAYE taxes, the tax rates are changed. In the current tax regime, after the tax exempted amount, every Rs.500,000 earned is taxed at 4 percent, 8 percent, 12 percent, 16 percent, 20 percent progressively, until a maximum tax rate of 24 percent. 
With the new system, after the tax exempt amount of Rs.500,000, every subsequent Rs.600,000 earned is taxed incrementally at 4 percent, 8 percent, 12 percent, 16 percent, 20 percent, up to a maximum of 24 percent. As the tax rates are increased at wider income blocks (i.e., at blocks of Rs.600,000 as oppose to blocks of Rs.500,000) the tax rates increase at a slower pace. For example, the tax rate of a person with an annual income of Rs.100,500 is 8 percent at present but with the new tax regime it will be only 4 percent. 


How do these changes to tax regime affect payment of taxes?


With the newly-introduced tax regime, less people are required to pay PAYE taxes, due to the tax exempt income threshold being higher. Also, as the tax rates increase at larger income blocks, individuals in the middle-income brackets would pay lower taxes than at present. But because under the new tax regime tax rates will increase beyond 16 percent, the rich are obliged to pay a higher tax rate than at present 


(Figure 1).


As the tax exempt threshold did not change for PIT taxes, there is no change in the number of individuals required to pay PIT. However, as with the PAYE taxes, those in the middle-income brackets pay lesser taxes, as the tax rates increase at a slower pace under the new system.

 


How will this affect tax revenue?


According to our simulations based on the Household Income and Expenditure Survey 2013/14 (HIES) data, the overall revenue from income taxes will decrease due to the proposed tax changes. This is mainly because there is a large revenue drop from lower PAYE taxes. However, it must be noted that the HIES does not capture the income levels of individuals with very high incomes, due to underreporting. Hence, the actual revenue collected may be higher than the estimated value. 


Although PAYE tax rates will increase for individuals with high incomes (monthly income of more than Rs.300,000), the number of taxpayers with such high incomes is low. One reason for the decrease in tax revenue is the higher threshold at which individuals are taxed. Although due to the higher

threshold less people pay taxes, the new tax regime has also removed concessions (e.g., the earlier tax regime provided a lower tax rate for professionals. Under the new system this has been removed) that are allowed under the current system. 

 


Is new system more pro-poor?


The new PAYE tax regime is slightly more progressive and income equalizing than the current PAYE tax system. This means, the richer will pay more personal income taxes than the poor. For example, according to our simulations, under the new tax regime, 98 percent of the revenue from the PAYE taxes will come out of the pockets of the richest 30 percent of Sri Lankans. 


This is an increase of three percentage points from the current tax regime. The increase in the share of PIT paid by the richest 30 percent of individuals also increases, albeit marginally. Under the new tax regime, 79 percent of the PIT will be paid by the 30 percent at the top of the income ladder.


Conclusion


The new tax regime is more income equalizing, as the richest pay a higher share of the taxes. However, if the main objective of the new tax regime is to increase tax revenue, our simulations show that this may not be achieved. On the other hand, along with the changes introduced to the tax regime, the new law eliminates deductions, which can also increase the tax revenue.


The Inland Revenue Department (IRD) is at present taking measures to improve tax administration to increase tax compliance and collection from high income earners. At present, only a small share of persons in each tax decile is actually paying taxes in Sri Lanka. 


According to the IRD, as of 2015, just 426,496 employees paid PAYE taxes and only 135,170 individuals paid PIT. If the tax administering process can be improved to net more tax payers, the revenue collected can increase. The share of individuals paying PIT is especially low. According to our estimates, only two out five required to pay PIT, is actually complying. Therefore, including more people in the tax net can increase the revenue collected.
