Somchain works as an engineer earning 50,000 baht

300 baht per month; pays 500 baht per person per month for life insurance.
The couple pays 120,000 Baht in mortage of which 60,000 baht is mortgage interest.
1. What is the income tax liability of Sochai if his files jointly with his wife?
2. Does Somchai owe any taxes? or does the government owe him a refund? How much refund?
Explanation / Answer
Monthly Income = 50000 baht
Annual Total Income = 50000 x 12 = 600000 Baht
LESS: Retirement Account Contribution = 12 x 300 = 3600 baht
LESS: Life Insurance Premium = 500 x 5 x 12 = 30000 baht
LESS: Mortgage Interest Payment = 60000 baht
Net Taxable Income = 506400 baht
(1) Income Tax Liability = 27500 + 15 % of amount exceeding 500000 baht = 27500 + 0.15 x 6400 = 27500 + 960 = 28460 baht
(2) Monthly Income withheld as advance tax = 3000 baht
Annual Advance Tax Paid = 3000 x 12 = 36000 baht
As the advance ta witheld is greater than the total tax liability, the government owes Somchai money and will refund the difference.
Tax Refunded = 36000 - 28460 = 7540 baht
