Singapore Side Income Tax Guide 2026: How to Report Freelance and Gig Earnings to IRAS
Last updated: June 2026 | SeaMoneyTips
Whether you drive for a ride-hailing platform, sell crafts online, or provide freelance consulting on weekends, any income you earn in Singapore is subject to tax. The Singapore side income tax rules apply to all residents who earn income beyond their primary employment. In this comprehensive guide, we break down everything you need to know about reporting freelance and gig economy earnings to the Inland Revenue Authority of Singapore (IRAS) for the 2026 tax year.
Ringkasan
In Singapore, all forms of income including side earnings from freelance work, gig economy jobs, rental income, and investment gains are taxable. If your total annual income exceeds S$20,000, you are required to file a tax return with IRAS. The key deadline is April 18 each year for paper filing, or April 18 for electronic filing via the myTax Portal. Side income is taxed at the same progressive rates as employment income, ranging from 0% to 22% for 2026. You can reduce your taxable income by claiming legitimate business expenses and applicable personal reliefs.
What Counts as Side Income in Singapore?
Side income refers to any earnings you receive outside of your primary employment. Under Singapore tax law, the following are considered forms of side income that must be declared:
- Freelance income: Earnings from freelance work such as graphic design, writing, photography, consulting, programming, or tutoring. This includes payments received from both local and overseas clients.
- Gig economy income: Earnings from platforms such as GrabFood, Deliveroo, Gojek, Foodpanda, or any other gig economy service. This also includes income from peer-to-peer services like TaskRabbit.
- Rental income: Money earned from renting out a room, a whole property, or even a parking lot. This includes short-term rentals such as those listed on Airbnb or similar platforms.
- Investment income: Dividends, interest, and gains from the sale of investments (though Singapore does not tax capital gains on investments held personally, dividend income is taxable if received through a trade or business).
- Part-time employment income: Wages from a second job or part-time position. This is taxed separately but combined with all other income for the year.
- Social media or content creation income: Sponsorship payments, affiliate commissions, ad revenue from YouTube, TikTok, or Instagram, and any income from content creation activities.
It is important to note that while CPF contributions from your employer are not considered taxable income, any side income you earn is subject to income tax regardless of whether you contribute CPF voluntarily.
Who Needs to File Taxes on Side Income?
Understanding who needs to file is crucial for staying compliant with Singapore tax regulations:
Employees with Side Income
If you are employed full-time and also earn side income, your employer already deducts tax via the No-Filing Service (NFS). However, if your total income exceeds S$20,000 and includes self-employment or freelance income, you must still file a tax return to declare those additional earnings.
Self-Employed Individuals
Freelancers, gig workers, and self-employed individuals must file a tax return if their total net trade income exceeds S$6,000. Even if your total annual income is below S$20,000, the self-employment income threshold of S$6,000 triggers a filing requirement.
Threshold Rules
- Employees earning more than S$20,000 in total income must file
- Self-employed individuals earning more than S$6,000 in net trade income must file
- Individuals with rental income must file regardless of amount
- Non-residents earning income in Singapore must file
How to Report Side Income to IRAS: Step by Step
Step 1: Determine Your Tax Residency
Before filing, confirm your tax residency status. You are considered a Singapore tax resident if you are a Singapore citizen, permanent resident, or have stayed in Singapore for 183 days or more during the year. Non-residents are taxed at a flat rate of 15% (or the progressive resident rate, whichever is higher) on income earned in Singapore.
Step 2: Calculate Net Trade Income
For self-employment and freelance income, you need to calculate your net trade income. This is your gross income minus allowable business expenses. Keep detailed records of all income received and expenses incurred throughout the year. Allowable expenses include:
- Cost of raw materials and goods sold
- Rental of equipment, office space, or co-working space
- Utilities and internet (proportional business use)
- Professional fees and subscriptions
- Travel expenses directly related to your business
- Insurance premiums for business-related coverage
- Depreciation of business assets
Step 3: File via myTax Portal
Log in to the IRAS myTax Portal using your SingPass. Follow these steps:
- Select Form B (for self-employed individuals) or Form B1 (for employees with additional income)
- Enter your employment income details from your IR8A
- Navigate to the self-employment or trade income section
- Enter your gross income from freelance or gig work
- Claim your business expenses to arrive at net trade income
- Review all sections for accuracy
- Submit your tax return before the deadline
The filing deadline for paper returns is April 15, while electronic filing via myTax Portal extends to April 18 each year.
Tax Rates for Side Income in Singapore 2026
Side income in Singapore is taxed at the same progressive rates as employment income. Here are the tax brackets for the Year of Assessment 2026:
| Chargeable Income (S$) | Tax Rate | Gross Tax (S$) |
|---|---|---|
| First 20,000 | 0% | 0 |
| Next 10,000 | 2% | 200 |
| Next 10,000 | 3.5% | 350 |
| Next 10,000 | 7% | 700 |
| Next 10,000 | 11.5% | 1,150 |
| Next 20,000 | 15% | 3,000 |
| Next 30,000 | 18% | 5,400 |
| Next 30,000 | 19% | 5,700 |
| Next 30,000 | 19.5% | 5,850 |
| Next 30,000 | 20% | 6,000 |
| Next 30,000 | 22% | 6,600 |
For example, if your combined employment income and freelance income totals S$80,000, your side income is combined with your salary to determine the applicable tax bracket. The progressive rates apply to the total chargeable income, meaning higher side income may push you into a higher tax bracket.
Deductions and Reliefs for Side Income Earners
As a side income earner in Singapore, you can reduce your tax liability through various deductions and reliefs:
Business Expenses
- Cost of goods sold: Raw materials, inventory, and packaging costs
- Workspace expenses: Proportional share of rent, utilities, and internet for your home office
- Equipment and tools: Laptops, cameras, software subscriptions used for work
- Professional development: Courses and certifications directly related to your freelance work
- Marketing costs: Website hosting, advertising, and promotional materials
- Transportation: Travel expenses for client meetings and business trips
CPF Reliefs
Self-employed individuals can claim CPF relief for voluntary contributions made to their MediSave account. This can significantly reduce your taxable income. You can contribute up to the annual MediSave contribution cap and claim the corresponding relief. Learn more about CPF self-employed schemes for details.
NSman Relief
If you are a Singaporean male who has completed National Service, you may be eligible for NSman relief. This relief is automatically assessed by IRAS for most individuals.
Working Mother’s Child Relief
If you are a working mother with side income, you may qualify for additional child relief that can further reduce your tax bill.
SRS Contributions
Contributions to the Supplementary Retirement Scheme (SRS) can also help reduce your taxable income. You can contribute up to S$15,300 per year (for Singaporeans and PRs) and enjoy tax relief on the contributed amount.
Common Mistakes to Avoid
Avoid these common pitfalls when reporting your Singapore side income tax:
- Late filing penalties: IRAS imposes a S$200 late filing penalty, and additional penalties of up to 200% of the unpaid tax can be imposed. File on time to avoid unnecessary costs.
- Under-reporting income: Always declare all sources of income. IRAS has access to data from banks, employers, and platforms. Discrepancies will trigger audits and penalties.
- Missing CPF contributions: Self-employed individuals must contribute to MediSave. Failure to do so means missing out on tax relief and potential penalties.
- Not keeping records: Maintain all income records, invoices, and expense receipts for at least 5 years. IRAS may request documentation during audits.
- Confusing capital and revenue expenses: Capital expenditure (like buying a laptop for business use) is treated differently from revenue expenses. Consult a tax professional if unsure.
- Ignoring overseas income: If you are a Singapore tax resident earning income from overseas clients, that income is generally taxable unless it was received in Singapore through an approved channel.
