Eligible years and changes
The digital service covers the current Year of Assessment (YA), advance YA for tax clearance only, and the previous four YAs, identified in this edition as YA 2022–2025. Submit within 30 days of the tax bill date. Permitted changes include income, deductions and reliefs, Parenthood Tax Rebate where the child’s PTR account has not been created, and residency from non-resident to resident where applicable. For other reasons or earlier years, send myTax Mail using Singpass or a Singpass Foreign user Account.
AIS income: missing, incorrect or counted twice
If AIS employment income or deductions are entirely missing from the bill, send the details through myTax Portal mail rather than entering them in this amendment service. Incorrect employer-provided AIS figures cannot be edited by the employee: contact the employer or organisation to resubmit corrected data; IRAS then revises the assessment automatically. If you also manually declared AIS income and it was assessed twice, remove the mistaken amount under Employer(s) Not under Auto-Inclusion Scheme and answer Yes when asked whether the reduction removes auto-included employment income.
Partnership and tax-clearance income
Partnership allocations follow the precedent partner’s filing; approach that partner for corrections rather than editing the allocation here. Tax-clearance employment figures come from the former employer, who must submit an additional or amended Form IR21. Income from another employer can be declared under Employment Income and Expenses.
Drafts and supporting documents
Sign in, select Amend Tax Bill and follow the retrieval instructions. Drafts remain for 14 days or until 30 December, whichever is earlier, and saving a draft is not submission. Upload every document requested at the Consolidated Statement before submitting. If documents are unavailable, use Save Draft on the form or statement. IR8A or certified accounts are required when prompted; IRAS may also request evidence later even if no upload prompt appeared.
Acknowledgement and later corrections
The Consolidated Statement becomes retrievable in View Notices within five days. If no acknowledgement appears after Submit, check View Notices, then the submission status under Amend Tax Bill. The service permits only one amendment of the bill; send full details of subsequent corrections via Compose Mail in myTax Portal.
Processing and assistance
The FAQ states that IRAS issues a revised digital or paper bill within five working days once the amendment has been processed; complex processing may take up to two months. IRAS notifies through the preferred channel when finalised or if more information is needed. Alternatives are myTax Mail, go.gov.sg/iras-livechat, 1800 356 8300 locally or +65 6356 8300 overseas. These procedures describe the 4 March 2026 edition.
