Singapore Tax Relief Optimizer & S$80,000 IRAS Cap Checker 2026
— Maximise Chargeable Income Deductions via myTax Portal

The S$80,000 aggregate personal income tax relief cap was introduced by IRAS with effect from YA 2018. It limits the total amount of personal tax reliefs a Singapore resident individual can claim in any single Year of Assessment to S$80,000, regardless of how many relief types they qualify for. The cap was introduced to ensure the tax relief system benefits a broad base of taxpayers rather than disproportionately benefiting high earners who can afford to maximize multiple reliefs simultaneously.

All personal income tax reliefs listed on your IRAS Form B1 count toward the cap. These include: Earned Income Relief (EIR), CPF/Provident Fund Relief (mandatory contributions), Spouse/Handicapped Spouse Relief, Qualifying Child Relief (QCR), Working Mother’s Child Relief (WMCR), Handicapped Child Relief (HCR), Parent/Handicapped Parent Relief, Grandparent Caregiver Relief (GCR), Handicapped Sibling Relief, NSman Relief (Self, Wife, and Parent), Life Insurance Relief, Course Fees Relief, Foreign Maid Levy Relief, SRS Relief, CPF Cash Top-Up Relief (Self and Family).

Two key items reduce your Singapore income tax but are applied before the S$80,000 cap is computed: (1) Allowable employment expenses (costs directly incurred to earn your employment income) reduce your assessable income; (2) Approved donations to Institutions of a Public Character (IPCs) at the 2.5× enhanced deduction rate also reduce assessable income. Because they reduce assessable income — not chargeable income — they operate independently of and effectively “outside” the S$80,000 personal relief cap.

The EIR for YA 2026 (income earned in 2025) is: S$1,000 for taxpayers below age 55; S$6,000 for those aged 55 to 59; and S$8,000 for those aged 60 and above. Handicapped taxpayers receive enhanced EIR: S$4,000 (below 55), S$5,000 (55–59), and S$8,000 (60+). EIR is automatically computed by IRAS based on your age and is included within the S$80,000 cap. You do not need to manually enter EIR when filing via myTax Portal using Singpass — it is pre-filled.

From YA 2025 onwards (announced in Budget 2024), WMCR switched from percentage-based to fixed-dollar amounts: 1st qualifying child — S$8,000; 2nd qualifying child — S$10,000; 3rd and subsequent children — S$12,000 each. Total WMCR per child is capped at S$50,000. Under the old system, relief was 15% of earned income for the 1st child, 20% for the 2nd, and 25% for the 3rd. Many competing tools still show the outdated percentage figures — ensure you are using the correct fixed amounts when filing on myTax Portal.

CPF Cash Top-Up Relief is entirely inside the S$80,000 aggregate cap. You can claim up to S$8,000 for voluntary top-ups made to your own CPF Special Account (SA) or Retirement Account (RA), and an additional S$8,000 for top-ups made to the SA/RA of family members (parents, siblings, or spouse). The combined maximum is S$16,000 per YA. Importantly, this S$16,000 counts toward — not separately from — your S$80,000 cap.

Yes, you can claim both Parent Relief and GCR for the same parent under certain conditions. Parent Relief applies if you supported the parent during the year (dependant income below S$4,000). GCR of S$3,000 applies specifically when a grandparent (or parent-in-law) looked after your child aged 12 or below in Singapore. However, you cannot claim GCR if the grandparent was also earning income from employment or was self-employed. Both reliefs are counted inside the S$80,000 cap.

Life Insurance Relief allows you to claim up to S$5,000 on qualifying life insurance premiums paid, but only if your total CPF contributions (mandatory employee share) for the year are less than S$5,000. This relief is specifically designed to benefit lower-income earners whose CPF contributions may be minimal. The S$5,000 cap for Life Insurance Relief is within the overall S$80,000 aggregate cap. You cannot claim this relief if your employee CPF contributions already exceed S$5,000 for the year.

Contributions to your Supplementary Retirement Scheme (SRS) account are deductible from your chargeable income — reducing your taxable income dollar for dollar, up to the annual contribution cap. For Singapore Citizens and PRs, the SRS cap is S$15,300 per year; for foreigners (Employment Pass holders), it is S$35,700. At a 15% marginal rate, maxing SRS at S$15,300 saves approximately S$2,295 in tax. Withdrawals from age 63 onwards are 50% taxable, making SRS an effective tax deferral strategy for retirement.

NSman (National Serviceman) Relief is available to Singapore citizens who have completed or are serving NS. For YA 2026, the self-relief amounts are: S$1,500 for inactive NSmen (no in-camp training in 2025); S$3,000 for active NSmen (attended at least one in-camp training in 2025); S$5,000 for NSmen holding key appointment positions. Additionally, wives and parents of NSmen can each claim S$750. All NSman reliefs count toward the S$80,000 aggregate cap.

IRAS applies the S$80,000 cap to the total of all your personal reliefs combined. For example, if your CPF/Provident Fund Relief is S$19,200 and your WMCR totals S$18,000 (two children), that’s S$37,200 of cap used before any other reliefs. Your remaining cap space is S$42,800 for EIR, NSman, SRS, CPF top-up, course fees and other reliefs. If total reliefs exceed S$80,000, IRAS disallows the excess — typically starting from the lowest-priority or most recently entered reliefs on your Form B1.

Foreign Maid Levy (FML) Relief is available exclusively to female Singapore taxpayers who employ a foreign domestic worker. The relief is twice the total levy paid during the year. At the current FDW levy rates for a first helper (S$300/month basic or S$450/month concessionary), a full year’s levy of S$3,600 gives S$7,200 in FML relief. This is inside the S$80,000 cap. The relief recognises the additional cost burden on working mothers and caregivers who employ domestic help to support their professional roles.

Donations made to approved Institutions of a Public Character (IPCs) qualify for a 250% (2.5×) tax deduction under the Singapore Income Tax Act. This deduction is applied at the assessable income level — before the S$80,000 cap is computed. A S$2,000 cash donation to an IPC gives S$5,000 in deductions from your assessable income. At a 15% marginal rate, this saves S$750 in tax — effectively a 37.5% return on your donation. The 2.5× deduction has been extended until 31 December 2026.

If your total personal reliefs exceed S$80,000, IRAS limits your total claimable relief to S$80,000. The excess is automatically disallowed — you do not receive any additional tax reduction beyond the cap regardless of how many reliefs you qualify for. IRAS applies reliefs in the order they appear on your Form B1 / myTax Portal filing. To optimise, prioritize reliefs that are harder to control (mandatory CPF, fixed family reliefs) first, then use flexible reliefs like SRS to fill the remaining cap space precisely.

You may amend your income tax return for the current year or the two preceding years via myTax Portal (log in with Singpass). For example, in 2026 you can amend YA 2026, YA 2025, or YA 2024 returns. To amend, log into myTax Portal, select “Object to Assessment” or “Amend Assessment” for the relevant year, and include the missed reliefs. IRAS will reassess your tax and issue a revised Notice of Assessment (NOA). Note that time-sensitive reliefs like SRS contributions and CPF Cash Top-Ups cannot be backdated — they must be made in the relevant calendar year.

Log into myTax Portal at mytax.iras.gov.sg using Singpass. Under “Individuals,” select “File Income Tax Return” for YA 2026. Many reliefs are pre-filled via the Auto-Inclusion Scheme (AIS) from your employer’s IR8A submission — including employee CPF contributions and EIR. For additional reliefs (SRS, CPF top-up, parent, course fees), scroll to the “Tax Reliefs” section and enter amounts manually. The portal shows a running total and alerts you if reliefs approach the S$80,000 cap. File by 18 April 2026 for e-filing (15 April for paper). Tax payable is then reflected in your NOA.
