Filing in Singapore is often faster than people expect — many employees don't even need to actively file, thanks to the Auto-Inclusion Scheme. Here's how it actually works.
Check if you need to file at all
If your income is fully covered under the Auto-Inclusion Scheme (AIS) — where your employer submits your income data directly to IRAS — and you have no other income to declare, you may not need to file anything. IRAS will notify you if action is required.
Log in to myTax Portal with Singpass
If you do need to file, log in to the myTax Portal using your Singpass. Employment income under AIS will already be pre-filled.
Declare additional income
Add any income not automatically included — rental income, freelance/trade income, or overseas income remitted to Singapore in specific circumstances.
Claim your reliefs
Enter details for reliefs you're eligible for — spouse, child, parent, course fees — beyond what's automatically applied. See our Tax Reliefs Guide for the full list.
Review your Notice of Assessment preview and submit
myTax shows an estimated outcome before submission. Review it, then submit — filing typically takes under 15 minutes for straightforward returns.
Know your numbers before you file.

Once your Notice of Assessment is issued, you can pay via GIRO (which allows interest-free installments), PayNow, or other methods within the payment deadline. See our IRAS Tax Deadlines guide for exact dates.
This is a general walkthrough of the standard filing process, not a substitute for IRAS's own instructions. For complex situations (multiple income sources, overseas income), consider professional advice.
