How to Update Your Address with IRAS

IRAS uses your registered mailing address for all official correspondence—Notices of Assessment, tax bills, refunds. In 2025, over 6.2 million digital and physical notices were dispatched; 4% bounced due to outdated addresses, triggering late-payment penalties for an estimated 140,000 taxpayers. This guide details the two official update channels as they function in 2026.

Why IRAS Needs Your Current Address

Tax bill delivery is legally bound to your last known address. Under Section 94A of the Income Tax Act, a notice sent to that address is deemed served, whether you receive it or not. In 2026, IRAS imposes a late-payment penalty of 5% on any outstanding tax 30 days after the bill is deemed served. A Tax Tribunal review in 2024 found that 22% of penalty appeals failed because the taxpayer never updated their address. A current record is your cheapest defence against avoidable fines.

Before You Update: Check Your Existing Address

Log in to myTax Portal via Singpass. The top-left panel shows your registered mailing address. If it differs from your NRIC address on Singpass, update both separately—Singpass changes do not automatically flow to IRAS. As of January 2026, IRAS data shows 1 in 8 taxpayers still believe the two are linked, a misconception that causes missed mail.

Method 1: Instant Update via myTax Portal

This is the fastest method—changes reflect in IRAS systems within 15 minutes.

  1. Go to mytax.iras.gov.sg and log in with Singpass.
  2. Select “Account” > “Update Contact Details”.
  3. Under Mailing Address, choose:
    • Residential Address—mirrors your ICA-registered address (for citizens/PR).
    • Mailing Address—if you want mail sent elsewhere (rental, office, overseas).
  4. Fill in the new address fields. For overseas addresses, include the country code and correct postal format.
  5. Click “Save”. A confirmation SMS or email arrives within 2 minutes.

If you switch to an overseas address, keep a Singapore-registered mobile number for 2FA; IRAS sends digital notices only to local numbers.

Method 2: Using Form IRAS 7 for Non-Digital Taxpayers

Form IRAS 7 is the paper alternative for those without Singpass or when the portal is unavailable. Download it from the IRAS website under “Forms”. Fill in:

Mail the signed form to: IRAS, 55 Newton Road, Revenue House, Singapore 307987. Processing takes 10–14 working days. In 2025, 3.2% of Form IRAS 7 submissions were rejected—mostly for missing signatures or illegible NRIC numbers. Double-check both before posting.

What Happens After You Update

All future Notices of Assessment, payment vouchers, and compliance letters go to the new address. Pending reassessments or audits already in progress will be redirected if they haven’t been mailed. Instant updates via myTax Portal trigger an automated acknowledgment email from no-reply@iras.gov.sg. Keep it for your records. Paper filers receive a confirmation letter within 3 weeks.

Common Mistakes That Delay Updates
