How self-employed in Singapore is calculated
Singapore’s resident rate scale is one of the gentlest in this catalog through the range most freelancers occupy: nothing on the first 20,000 SGD, and still only 7% at 80,000. The top rate of 24% arrives only above a million, so the effective rate on a good professional income remains strikingly low by international comparison.
The compulsory saving is where the self-employed differ from employees. A self-employed person contributes to MediSave only — not to the Ordinary and Special CPF accounts an employee accumulates — so the mandatory deduction is far smaller, and retirement provision beyond healthcare is left entirely to you. The rate is age-banded and phases in between 6,000 and 18,000 SGD of net trade income.
Worked example
| Annual net trade income (SGD) | 90000 |
|---|---|
| MediSave contribution ✓ | 7200 |
| Income tax ✓ | 4500 |
| Net income / year ✓ | 78300 |
Every row is computed by the engine from the inputs above. Rows marked ✓ are additionally pinned by a published self-test vector.
Frequently asked questions
How much tax on 90,000 SGD of net trade income?
About 4,500 SGD of income tax under the resident rates, plus roughly 7,200 SGD of MediSave at the under-35 rate — leaving about 78,300 SGD before personal reliefs.
Do self-employed people pay CPF in Singapore?
Only MediSave. The Ordinary and Special accounts that employees build are not funded for the self-employed, which is why the compulsory deduction is much smaller and why retirement adequacy is your own responsibility.
What is the MediSave rate?
Age-banded, from 8% below 35 to 10.5% at 50 and above, phasing in between 6,000 and 18,000 SGD of net trade income and capped in practice. This model applies the flat under-35 rate.
