1. Do I need to file an Income Tax Return?
Find out if you need to file an Income Tax Return for Year of Assessment 2021:
You may be selected for the Direct Notice of Assessment initiative if you only had auto-included income in the previous year. You do not need to file an Income Tax Return. Your tax bill would be computed based on your income provided by your employer and previous year’s relief claims. A taxpayer selected to receive the Notice of Assessment without the need to file has a legal duty to inform IRAS of any inaccurate information on his income and/or relief claims in his tax bill. There are penalties for failing to do so.
2. Received a letter or SMS about No-Filing Service (NFS)?
If you received a letter or SMS informing you that you have been selected for NFS, you are not required to file an Income Tax Return. However, if you wish to make any adjustments to your income details or relief claims, please log in to myTax Portal to file your Income Tax Return.
Your Notice of Assessment or tax bill (digital or paper format) will be sent to you from end Apr onwards. Please note that it is your responsibility to ensure that your tax bill is accurate. If you have any other income that is not shown in the tax bill, or if your relief claims in the tax bill are incorrect, you must inform IRAS of any discrepancy through the “Object to Assessment” digital service at myTax Portal within 30 days from the date of your tax bill.
3. What information do I need to file my Income Tax Return?
Before you log in to myTax Portal, make sure you have these documents ready:
- Singpass/Singpass Foreign user Account (SFA)
- Form IR8A (if your employer is not participating in the Auto-Inclusion Scheme)
- Particulars of your dependants (e.g. child, parent) for new relief claims
- Details of rental income from your property (e.g. gross rent, expense claims) and other income, if any
- Business registration number/partnership tax reference number (for self-employed and partners only)
4. What if I require more time to file my Income Tax Return?
If you need additional time to file your Income Tax Return, please use the 'Request Extension of Time to File' (PDF, 1.09MB) digital service.
5. Do I need to declare my employment income information?
If your employer is participating in the Auto-Inclusion Scheme (AIS) for Employment Income, they will submit your income information to IRAS by 1 Mar of each year.
You may use the AIS Organisation Search to check if your employer:
- is in the AIS; and
- has submitted for Year of Assessment 2021.
If your employer is not participating in the 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.
You are not required to submit your Form IR8A or other supporting documents unless specifically stated at the acknowledgement page.
6. Which income is taxable, which is not?
Generally, all income earned in Singapore is subject to tax. Find out more about the taxability of the different types of income (e.g. employment, trade).
7. 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. Please use the Rental Calculator (XLS, 356 KB) to decide if it is beneficial to claim 15% deemed rental expenses or to claim based on actual rental expenses incurred.

You may claim personal reliefs and rebates if you are a 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 2020).
