Understanding rental income tax

Is rental income taxable in Sri Lanka?

Yes. Rental income is generally part of your income for tax purposes. The final tax depends on your total income, available reliefs, and the way the rental property is treated.

What is 25% rent relief?

In simple terms, this means only part of your rental income may be taxed after applying the permitted rental relief. This calculator uses a simple 25% relief estimate unless you choose actual expenses instead.

Why does other income matter?

Sri Lanka uses progressive tax slabs. This means rental income can be taxed differently depending on your salary, business income, FD interest, and other income.

Formula used

  1. Annual Rent = Monthly Rent × Months Rented
  2. Rent Relief = 25% of Annual Rent, unless actual expenses are selected
  3. Rental Income After Deduction = Annual Rent − Relief / Expenses
  4. Total Income = Other Annual Income + Rental Income After Deduction
  5. Taxable Income = Total Income − Personal Relief
  6. Extra Tax From Rent = Tax with rental income − tax without rental income
