FAQs

1. My pre-filled employment income is wrong, what should I do?

Your employer has submitted your income information for the year 2025 (Year of Assessment 2026) to us directly. For any discrepancy, please check with your employer directly. They will resubmit the information to us if there are errors in the original submission, and this will be included in your tax bill.

2. My employer is not under Auto-Inclusion Scheme (AIS), what information do I need to file my Income Tax Return?

If your employer is not participating under AIS, your employer should have provided you with the Form IR8A by 1 Mar. You should enter the details during your tax filing as per the information in your Form IR8A. If you do not have the Form IR8A, please request for it from your employer.

You are not required to submit your Form IR8A or other supporting documents unless specifically stated at the acknowledgement page after you have filed.

3. Can I claim personal reliefs and rebates?

You may claim personal reliefs and rebates if you are Singapore tax resident and have met the qualifying conditions for the respective reliefs/rebates in the preceding year (i.e. 1 Jan to 31 Dec 2025).

4. Can I claim expenses?

Generally, you may claim tax deductions on expenses "wholly and exclusively" incurred in earning your income. Find out more about deductions for the different types of expenses (e.g. employment expenses, business expenses). 

To simplify the tax filing for rental expenses, you may opt to claim the rental expenses based on 15% of the gross rental income derived from the tenanted residential property, instead of the actual amount of deductible expenses incurred. In addition to the 15%, you may claim a deduction on interest paid on the loan taken to purchase the property. You may use the Rental Calculator (XSLM, 146KB) to decide if it is beneficial to claim 15% deemed rental expenses or to claim based on actual rental expenses incurred. Find out more about the Simplification of Claim of Rental Expenses for Individuals.

5. What if I require more time to file my Income Tax Return?

If you need additional time to file your Income Tax Return, an extension of up to 14 days may be granted. You may use 'Apply for Extension of Time to File' digital service at myTax Portal
