Statutory Overview & Legal Tax Framework
Personal income tax in Singapore is levied by the Inland Revenue Authority of Singapore (IRAS) under the Income Tax Act 1947 (Cap. 134) on a preceding-year, territorial basis - meaning YA 2026 taxes income earned from 1 January 2025 to 31 December 2025, and only income sourced from or received in Singapore (with limited exceptions) is chargeable. Singapore's progressive resident tax system spans 13 brackets, rising from 0% on the first S$20,000 of chargeable income to a top marginal rate of 24% on chargeable income exceeding S$1,000,000. This makes Singapore one of the most competitive personal income tax regimes among developed economies globally. For YA 2026, no Personal Income Tax rebate was announced - unlike YA 2024 (where a 50% rebate capped at S$200 was granted) - meaning all chargeable income is taxed at the full applicable progressive rate. Chargeable income is computed by taking total gross income (employment income, trade income, rental income, director's fees) and deducting eligible personal tax reliefs. Singapore provides one of the world's most generous personal tax relief systems, offering residents the ability to reduce taxable income through: Earned Income Relief (S$1,000 to S$8,000 depending on age; enhanced amounts for persons with disabilities), mandatory CPF Employee Contributions Relief (on contributions to the Ordinary, Special, and MediSave accounts up to statutory wage ceilings), voluntary SRS contributions (S$15,300 for Citizens/PRs; S$35,700 for foreigners), Working Mother's Child Relief (WMCR fixed amounts: S$8,000 / S$10,000 / S$12,000 per child order), Qualifying Child Relief (S$4,000 per child), Parent Relief (up to S$9,000 per dependent parent or grandparent), NSman Relief, Life Insurance Relief (up to S$5,000 per year if CPF relief does not exceed S$5,000), and CPF Cash Top-Up Relief. All reliefs combined are subject to an S$80,000 aggregate personal tax relief cap per Year of Assessment - any relief claiming above this cap is automatically discarded by IRAS. Foreign-sourced income and investment gains must be analysed by income type: many personal investment gains and many foreign dividends received by resident individuals are not taxable, but partnership income, trading income and specific exceptions can still be taxable. Employers under the Auto-Inclusion Scheme (AIS) submit income data directly to IRAS by 1 March 2026, pre-filling most salaried employees' Form B1 returns automatically. Taxpayers can then review, update relief claims, and file electronically between 1 March and 18 April 2026 via Singpass-authenticated myTax Portal. Tax is payable within 30 days of the Notice of Assessment (NOA) date - or via a 12-month interest-free GIRO installment plan to avoid any late payment penalties.
Key Tax Criteria & Statutory Rules

IRAS enforces a strict S$80,000 per-year-per-individual cap on the total of all personal income tax reliefs combined. This includes: CPF Employee Contributions Relief, SRS contributions, Earned Income Relief, WMCR, Qualifying Child Relief, Parent Relief, NSman Relief, Life Insurance Relief, CPF Cash Top-Up Relief, and all other personal reliefs. Relief amounts exceeding the cap are automatically discarded. Strategic planning of relief mix is essential each year to maximize tax savings within the cap.
EIR is automatically granted by IRAS to all working individuals: S$1,000 (below age 55); S$6,000 (age 55-59); S$8,000 (age 60 and above). Enhanced EIR for persons with disabilities: S$4,000 (below 55); S$10,000 (age 55-59); S$12,000 (age 60+). EIR is counted within the S$80,000 cap. No application is required - it is automatically credited when you file or are placed on NFS.
Tax residents can deduct the full amount of mandatory employee CPF contributions from taxable income. The Ordinary Wage (OW) ceiling was raised to S$6,800/month effective 1 January 2025 (from S$6,300/month), increasing the maximum annual CPF-OW-based contribution base. Contributions to OA, SA, and MediSave all qualify. From YA 2026, eligible self-employed persons can claim relief on the full compulsory MediSave contribution without prior caps.
Every dollar voluntarily contributed to an SRS account (DBS, OCBC, or UOB) reduces taxable chargeable income dollar-for-dollar: S$15,300/year for Singapore Citizens and PRs; S$35,700/year for foreigners holding Employment Passes. Contributions must be credited by 31 December to qualify for the following Year of Assessment. SRS deductions are automatically pre-filled by IRAS from bank-reported data - no manual filing needed.
From YA 2025 onwards, WMCR was converted from a percentage-based system to fixed monetary amounts: S$8,000 for the 1st child, S$10,000 for the 2nd child, and S$12,000 for the 3rd and each subsequent child. Claimant must be a married, divorced, or widowed working female Singapore Citizen. WMCR cannot be combined with Qualifying Child Relief (QCR) for the same child in the same YA.
Resident taxpayers supporting parents, grandparents, parents-in-law, or grandparents-in-law who live in Singapore, are aged 55 or above, have an annual income not exceeding S$4,000, and are not claiming their own relief can claim: S$5,500 (parent not residing with you) or S$9,000 (parent residing with you in the same household). Handicapped parent relief is S$10,000 (not residing together) or S$14,000 (residing together).
Life Insurance Relief: up to S$5,000/year on premiums paid for life policies on your own life or your spouse's life, but only if your total CPF contributions are less than S$5,000. CPF Cash Top-Up Relief: up to S$8,000/year for cash top-ups to your own CPF SA/RA, plus an additional S$8,000/year for top-ups to your spouse's or sibling's CPF SA/RA - total of up to S$16,000/year. Both count within the S$80,000 cap.

IRAS Filing & Verification Checklist
Step-by-Step IRAS Filing & Payment Workflow
Check NFS Notification - Determine if Filing Is Required for YA 2026
In February 2026, check if you received an IRAS No-Filing Service (NFS) SMS notification or postal letter. NFS means IRAS will automatically issue your NOA without requiring you to file - you only need to log in to verify pre-filled details. If you did NOT receive NFS notification, you must proactively file Form B1 on myTax Portal between 1 March and 18 April 2026.
Log into myTax Portal via Singpass & Access Form B1
Access mytax.iras.gov.sg using your Singpass account (biometric app or SMS OTP). Select 'File Income Tax Return' x- ' 'Individuals' x- ' 'Form B1 (Resident)'. The portal will display your pre-filled gross income from AIS employer submissions and your pre-filled personal relief amounts from CPF Board and SRS bank data.
Verify Pre-Filled AIS Income & Declare Additional Non-Employment Income
Review and confirm your AIS-pre-filled employment income matches your Form IR8A. Declare any additional income not covered by AIS: Singapore rental income (gross rent from tenants), trade or self-employment net profit, director's fees from non-AIS companies, commission income from freelance work, or any other Singapore-sourced taxable income for calendar year 2025.
Review and Optimize All Personal Tax Relief Claims
Carefully review pre-filled relief amounts: Earned Income Relief (check age tier is correct), CPF Employee Contributions (verify against CPF annual statement), SRS (verify against SRS statement). Add any new reliefs applicable for YA 2026: new child born in 2025 (QCR S$4,000 or WMCR S$8,000), new dependent parent (Parent Relief), life insurance premium paid, or CPF cash top-up made in 2025. Ensure total reliefs do not exceed S$80,000.
Review Tax Computation Summary Before Final Submission
Before submitting, review the myTax Portal tax computation summary showing: (a) total gross income; (b) total personal reliefs claimed; (c) chargeable income (gross income minus reliefs); (d) tax computed bracket-by-bracket; (e) net tax payable for YA 2026. Verify your effective tax rate and marginal rate. If any figures appear incorrect, adjust before submission - amendments after submission require a Notice of Objection.
Submit Form B1 Electronically Before 18 April 2026
Click 'Submit' on myTax Portal to file your Form B1 return. An instant digital acknowledgement number is issued upon successful submission. Save or screenshot the acknowledgement for your records. If you cannot submit by 18 April, request assistance or an extension through the official IRAS channel before the deadline; extensions are not automatic.
Receive NOA, Set Up GIRO & Pay Tax Bill
IRAS issues Notice of Assessment (NOA) from April 2026 onwards - viewable on myTax Portal and sent by post. Tax must be paid within 30 days of NOA date. Enroll in GIRO via your internet banking portal (add IRAS as GIRO recipient using your NRIC as the reference) before the due date to automatically split your tax bill into 12 equal interest-free monthly deductions - no penalty applies once GIRO is active.
