8. I may have overlooked to claim for business expenses or reliefs, or incorrectly declared my income. How can I amend my tax bill?

Question

Accepted Answer

Please use the 'Amend Tax Bill' digital service on myTax Portal to amend your tax bill for any of the following purposes:

Revise income declaration;
Add or amend claims for deductions and reliefs;
Claim Parenthood Tax Rebate (PTR) (if the PTR account has not been created for your child); or
Change in tax residency status (from non-resident to resident, if applicable).

Once your amendment has been processed, IRAS will issue your revised tax bill (digital/ paper) within 5 working days. For more complex cases, processing may take up to 2 months. We will notify you via your preferred notification mode when your revised tax bill is finalised or if more information is needed.

Find out whether your income is taxable and what tax reliefs you can claim:

Personal Reliefs: Check your eligible reliefs using the Personal Relief Checker
- Note: Total personal relief is capped at $80,000
PTR: Check eligibility with the PTR Eligibility Tool (XLSM, 67KB)
