Declaring side income
All income earned in Singapore must be declared to IRAS, including freelance work, gig economy earnings, rental income, and side business profits. Side income is added to your employment income and taxed at progressive rates. You can deduct expenses incurred to earn the side income.
MediSave for side earners
If your net trade income from self-employment exceeds S$6,000, you are required to contribute to MediSave. This applies even if you are already employed and contributing to CPF through your employer. The MediSave contribution is based on your net trade income.
GST obligations
If your total taxable turnover (including side income from taxable supplies) exceeds S$1 million, you must register for GST. This is calculated on a rolling 12-month basis or a forward-looking 12-month basis.

How IRAS taxes income from side hustles, freelance gigs, and part-time work
Is side income taxable in Singapore?
Yes. All income earned in Singapore is taxable, including side hustles, freelance gigs, part-time jobs, tuition, and online sales. If you have a full-time job and earn extra money on the side, the side income is added to your employment income and taxed at progressive rates. There is no minimum threshold below which side income is tax-free.
How does side income affect your tax bracket?
Side income is stacked on top of your main employment income. If your salary puts you in the 7% bracket (S$40,001 to S$80,000), your side income may be taxed at 7%, 11.5%, or even 15% depending on how much it adds. For example, a S$60,000 salary plus S$25,000 side income gives S$85,000 total — the top S$5,000 is taxed at 11.5% instead of 7%.
Do you need to pay MediSave on side income?
If your net trade income (income minus expenses) from self-employed activities exceeds S$6,000 per year, you must contribute to MediSave. This applies even if you already pay CPF through your main job. The MediSave rate is 8% to 10.5% depending on your age and income level. If your side income is from employment (a second job), the employer handles CPF.
What expenses can you deduct from side income?
If your side income is from a trade (freelancing, tutoring, selling products), you can deduct expenses directly related to earning that income. Examples: art supplies for illustration work, a laptop used for freelance writing, transport to clients, platform fees (Grab, Carousell), and marketing costs. Keep receipts and only claim expenses used for business, not personal use.
How do you declare side income on your tax return?
Report trade income from side hustles under "Trade, Business, Profession, or Vocation" on Form B. If your side income is from a second employer, it should appear on a separate IR8A form from that employer. For platform income (like Grab or food delivery), you may need to total up your own earnings. IRAS expects you to keep records even for small amounts.
Do you need to register a business for your side hustle?
If you are trading under a business name, you should register a sole proprietorship with ACRA (S$100 for one year). If you use your own name and the income is occasional, registration is not strictly required. However, registering makes your business look professional, gives you a UEN for invoicing, and separates business and personal finances cleanly.
How much tax will you pay on S$10,000 of side income?
It depends on your total income. If your main salary is S$50,000 and you add S$10,000 side income, the extra tax is roughly S$700 to S$1,150 (taxed at 7% to 11.5% marginal rate). If your salary is S$100,000, the same S$10,000 side income costs about S$1,500 in extra tax (at the 15% marginal rate). Higher earners pay more tax on the same side income.
