How Singapore income tax is calculated: a YA 2027 worked example

Rates checked 2 November 2026 · Go Home Early

Singapore taxes income earned in a calendar year in the following Year of Assessment (YA). Income earned in 2026 is assessed in YA 2027. Salary is paid in full each month, with only CPF taken out, and the tax is billed after filing. This guide takes one salary of S$96,000 through the IRAS steps for a citizen or PR, a tax-resident foreigner and a non-resident foreigner.

The resident rates

IRAS labels its resident rates "YA 2024 onwards", so they cover YA 2027. Tax is charged on chargeable income, which is income less reliefs, band by band.

The first S$20,000 of chargeable income is taxed at 0%. Each rate applies only to the part of income inside its own band, so moving into a higher band never lowers the pay after tax.

Step 1: reliefs

Two reliefs apply to almost every employee. Earned Income Relief is S$1,000 under age 55, S$6,000 from 55 to 59 and S$8,000 from 60, using the age at 31 December, and it cannot be more than earned income. CPF relief equals the compulsory employee CPF, and only citizens and PRs get it. All reliefs together are capped at S$80,000 a year. Many other reliefs exist (spouse, children, parents, course fees, SRS and others) and this calculator does not include them. The IRAS pages read show YA 2026 amounts, and the same amounts are used for YA 2027.

Step 2: a worked example

A salary of S$96,000, age 30, paid as S$8,000 a month, no bonus. A citizen or PR pays S$19,200 of employee CPF (20% of S$96,000, since S$8,000 is exactly the ceiling).

For the citizen, reliefs of S$20,200 bring S$96,000 down to S$75,800. The tax by band:

The last dollars are taxed at 7%, but the tax as a share of salary is 3.18%. The tax-resident foreigner has no CPF relief, so the chargeable income is S$95,000 and the tax S$5,075.00, though the foreigner also paid no CPF out of pay.

Age changes the relief

Earned Income Relief rises with age. On the same salary:

The employee CPF also changes with age (see the first guide), and CPF relief follows it, so the chargeable income moves by more than the Earned Income Relief alone.

Non-residents

A foreigner who spends fewer than 183 days in Singapore in the year is a non-resident for that year. IRAS taxes the employment income of a non-resident at the flat rate of 15% or the progressive resident rates, whichever gives the higher tax, and a non-resident gets no personal reliefs. On S$96,000 that is S$14,400.00 (the flat rate S$14,400.00 against S$5,190.00 at resident rates). On S$60,000 it is S$9,000.00, and on S$400,000 the resident rates win, S$62,150.00 against S$60,000.00 flat.

When the tax is paid

The employer does not withhold income tax from the monthly salary. The tax is assessed after the year, so a monthly salary calculation such as the CPF guide is before it. A fair planning figure is the yearly tax divided by twelve: S$255 a month in this example. This payment arrangement is how the calculator is built, and it was not read from an IRAS page in this check.

Not included: personal income tax rebates and any measure announced in Budget 2026, reliefs other than the two above, and rounding of chargeable income by IRAS.
