Singapore eCommerce tax matters more than ever as more people turn their side hustles into real income. If you sell, stream, or provide services online, knowing when your income becomes taxable and how the Goods and Services Tax (GST) applies can save you from unexpected bills later.
Many creators and small sellers don’t realise that once their online work becomes regular and profit-driven, it’s treated like any other business activity in Singapore.
This guide helps you understand:
- When your online income becomes taxable, and what counts as a business activity.
- When and how to file your tax return, even if you’re earning part-time.
- How GST works for online sales, exports, and digital services under Singapore’s eCommerce tax rules.
- What records to keep so you stay audit-ready and avoid IRAS penalties.
- What to do if you pause or close your online business, including GST and MediSave steps.
What is “Singapore eCommerce Tax” and why does it matter
If you make money online, whether by selling products, offering services, or creating content, Singapore eCommerce tax rules may apply to you. This includes:
- Renting or selling goods on platforms such as Carousell, Shopee, Lazada, or Shopify
- Providing services such as design, tutoring, virtual assistance, delivery, household help, webinars, or consulting
- Earning from content through ads, subscriptions, affiliate links, or commissions
If you carry out these activities regularly and with the intention of making a profit, your income is considered taxable, even if it is part-time or a side hustle.
If you use overseas platforms such as Amazon US but do most of the work from Singapore, for example, choosing products or managing fulfilment, that income is still considered Singapore-sourced and taxable here.
However, selling your own used personal items that you originally bought for yourself and are not reselling for profit is generally not taxable.
Skip the confusion.
When online sellers must file a tax return in Singapore
You need to file an individual tax return if any of the following apply:
- You receive a letter, form, or SMS from the Inland Revenue Authority of Singapore (IRAS) asking you to file.
- Your annual net trade income (gross income minus deductible expenses from online activities) exceeds S$6,000.
- Your total annual taxable income (including any employment income) exceeds S$22,000.
When to file Singapore eCommerce tax
You must file for income earned in a calendar year by logging in to the myTax Portal between 1 March and 18 April the following year. Missing the deadline is an offence.
Examples:
- If your net trade income is S$4,000 and your employment income is S$20,000, your total taxable income is S$24,000. Since this is above S$22,000, you must file a return.
- If you are on the No Filing Service (NFS) through your employer’s Auto-Inclusion Scheme but also earn online income (for example, from tutoring or freelancing), you still need to file a return to report that income.
- If you are under 21 and earn more than S$6,000 from online work (such as affiliate marketing), you must file a return. Your parent or guardian will be responsible for the filing and will receive the Notice of Assessment.
Note: If you run your online business through a registered company, you must follow corporate tax filing requirements instead of individual filing.
How to file your Singapore eCommerce tax return (step-by-step)
1. Keep proper records
- Record every sale and expense related to your online business.
- Keep these records for at least five years.
- You can use Simplified Record Keeping if you meet IRAS conditions.
- Use IRAS-approved accounting software and a separate business bank account to track transactions easily.
- If you cannot support your numbers with documents, IRAS may increase your declared income.
- At the end of your financial year, prepare a Profit and Loss statement and a Balance Sheet to use when filing your return.
2. Report your income correctly
In your tax return, declare income under “Trade, Business, Profession or Vocation.”
Most online sellers will use a 4-line statement:
- Revenue: All income from your online activities, such as sales, ad revenue, and commissions. No estimates allowed.
- Gross Profit or Loss: Revenue minus cost of goods sold.
- Allowable Business Expenses: Only expenses directly related to earning income, such as product costs, platform fees, advertising, or content production. Personal or private costs are not allowed.
- Adjusted Profit or Loss: The result after deducting expenses.
If your revenue is below a certain level, you may file a 2-line statement showing only:
- Revenue
- Adjusted Profit or Loss
Examples:
- A seller earning S$50,000 from antiques and S$20,000 from ad revenue must declare S$70,000 in total income.
- A tutor who earns S$20,250 must report the exact amount, not a rounded estimate.
- If your business spent S$32,000 on products and S$8,000 on ads, you can deduct S$40,000 in total. Personal trips or private car costs cannot be claimed.
3. Include other income & claim reliefs
- Add any other taxable income, such as rental earnings.
- If your employer is on AIS, salary may be auto-included. Check and add anything missing.
- Claim all eligible personal reliefs and rebates before submitting your return.
Compulsory MediSave for self-employed eCommerce sellers in Singapore
If you are self-employed and earn income from online selling or services, you must contribute to MediSave once your net trade income (after deducting business expenses) is more than S$6,000 a year.
The CPF Board will inform you when this applies to you, based on your income reported to IRAS.
What this means for you
- If you sell products on Shopee, Lazada, or Shopify, or provide online services like tutoring or design work, set aside money for MediSave along with your income tax and GST payments (if registered).
- Keep your records accurate so your MediSave contributions are calculated correctly. This helps you avoid penalties and unexpected payments later.
- If you are new to online business, include MediSave planning when reviewing your Singapore eCommerce tax and GST obligations.
Closing or pausing your online business: Tax steps for eCommerce sellers
If you stop or take a break from selling, you still have some Singapore online shopping tax steps to complete.
Before you close or pause:
- Report all income earned up to the date you stopped in the correct Year of Assessment.
- If you are a foreign seller, inform IRAS immediately when your business activities in Singapore end.
- If your business is registered with the Accounting and Corporate Regulatory Authority (ACRA), you must also submit a cessation filing there.
- Keep all records for at least five years, in case IRAS needs to check them.
- If you are GST registered, submit your final GST return and apply to cancel your GST registration if you are eligible.
Why this matters:
Finishing these steps properly helps you avoid late filings, estimated assessments, or penalties, and makes it easy to restart your business later if you choose to.
IRAS compliance checks and voluntary disclosure
IRAS regularly checks online business records to make sure sellers report their income correctly. They compare information from marketplaces, payment platforms, and shipping companies to verify what you have declared.
If your income or GST reports are inaccurate, IRAS can issue additional tax bills, apply business penalties, or, in serious cases, take legal action.
How to stay audit-ready:
- Keep source documents (invoices, platform statements, shipping/export proofs) for 5 years.
- Reconcile sales across all channels (marketplaces, webstore, social).
- Separate local vs export sales for accurate Singapore online shopping tax and GST treatment.
If you find an error in your past filings, use the IRAS Voluntary Disclosure Programme. Reporting mistakes early helps you correct them and may reduce penalties.
Common reasons to make a disclosure:
- You forgot to report income from an online marketplace.
- You applied the wrong GST rate or did not have documents to support export sales.
- You claimed expenses that are not tax deductible.
GST basics for eCommerce and online services in Singapore
The Singapore eCommerce tax applies the same way whether you sell through a marketplace, your own website, or even offline. If your goods or services are supplied in Singapore, you need to follow local GST rules.
Current GST rate in Singapore
- The GST rate is 9%, effective from 1 January 2024.
- It applies to most goods and services sold locally, unless a special zero-rated or out-of-scope rule applies.
When do online sellers register for GST?
- If your annual revenue exceeds S$1 million in any calendar year, you must register for GST.
- Use the GST Registration Calculator on the IRAS website to check.
- Register on time to avoid penalties or having to pay backdated GST.
How GST applies to physical goods sold online
- Local deliveries (within Singapore): Charge 9% GST on all orders delivered to Singapore addresses.
- Exports (outside Singapore): You can charge 0% GST if you keep the required export documents, such as a courier note and invoice.
- Outside-to-outside shipments: If goods are delivered from one overseas location to another, the sale is out of scope and you do not charge GST.
Low-value goods (under the OVR regime):
- From 1 January 2023, GST also applies to low-value goods worth S$400 or less that are delivered to Singapore by air or post.
- Both local and overseas sellers, marketplaces, and delivery agents may have to register for GST and charge it on these items.
How GST applies to services and digital services
- Services for customers in Singapore: Usually charged at the standard GST rate of 9%.
- International services: You can charge 0% GST only if:
- The service is provided to someone outside Singapore or a GST-registered business in Singapore.
- The service is not directly linked to land or goods in Singapore.
- You have proper evidence, such as contracts or customer details.
Imported remote services (under OVR):
- Since 2020, GST applies to imported digital services (like streaming or software).
- From 2023, it also covers non-digital services provided remotely to Singapore customers.
- Some overseas suppliers and online marketplaces must register for GST and collect it on behalf of customers.
Determining where your customer belongs:
- To decide whether GST applies, check if your customer is in Singapore.
- You can use practical clues such as a Singapore address, a .sg email, or a Singapore IP address.
- If you are registered under the OVR regime, follow the rules in the official IRAS e-Tax guides for confirmation.
Common eCommerce items (Quick GST guide)
Software
- Standard (off-the-shelf) software: GST treatment depends on how it is delivered. If it is sold as a physical product (like a CD), it is treated as goods. If it is downloaded online, it is treated as a digital service.
- Custom software: Always treated as a digital service, so GST rules for services apply.
Virtual items in games
- Items such as in-game currency, clothing, or upgrades are considered digital services.
- If you sell them for real money or digital payment tokens as part of a business, you must charge GST.
Online advertising, hosting, and server services
- Services such as web advertising, website hosting, or server co-location can be zero-rated (0% GST) if they qualify as international services.
If they do not meet those conditions, you must charge standard GST (9%).
GST return for eCommerce sellers: Easy filing checklist
Before you file your GST return, make sure you have completed these steps:
- Confirm your GST registration: Check whether you are GST registered and know your filing cycle (usually quarterly).
- Combine your sales data: Include revenue from all channels such as marketplaces, your webstore, and social media.
- Separate local and export sales: Keep export documents to support zero-rated (0%) sales.
- Check for OVR exposure: This includes low-value goods and remote services.
- Work out your GST:
- Output tax is the GST you charge customers.
- Input tax is the GST you paid on business purchases that you can claim back.
- File your return on time through myTax Portal (usually every quarter).
- Keep all records for 5 years, including invoices, platform reports, and shipping documents.
Tip: GST rules for online sellers can be detailed and sometimes confusing, especially when you sell across different platforms or countries. Getting help from a qualified professional or a trusted partner can make your filings easier, more accurate, and stress-free.

FAQs on Singapore eCommerce tax
Do online sellers in Singapore have to pay tax?
Yes. Income from online activities undertaken for profit (whether part-time or full-time) is taxable. If your core business operations are in Singapore, income earned through overseas platforms (e.g., Amazon US) is generally Singapore-sourced and taxable here.
When must an eCommerce seller file a tax return in Singapore?
File an individual return if IRAS asks you to, if net trade income exceeds S$6,000, or if total taxable income exceeds S$22,000. File via myTax Portal between 1 Mar and 18 Apr for the prior calendar year.
What is the current GST rate for online sales in Singapore?
The GST rate is 9% (effective 1 Jan 2024). It applies to most local supplies to Singapore customers unless a specific zero-rating or out-of-scope rule applies (e.g., qualifying exports or outside-outside supplies).
When do online sellers need to register for GST?
Register if your taxable turnover exceeds S$1 million in any calendar year (or is expected to). Use the GST Registration Calculator, register on time, and then charge 9% GST on standard-rated local supplies and file quarterly GST returns for eCommerce sellers.
I sell used personal items in Singapore. Do I pay tax or GST?
Occasional sales of used items primarily bought for personal use (not for resale) are generally not taxable. GST treatment depends on your registration status and whether you are in business; casual, one-off sales of personal goods typically fall outside business activity.
Do minors or side-hustlers need to file income tax in Singapore?
Yes, if net trade income > S$6,000 or total taxable income > S$22,000, you must file, regardless of age or part-time status. For minors, a guardian is responsible for filing. Employment income on AIS may be auto-included, but online income still needs reporting.
What records should eCommerce sellers keep for tax and GST?
Keep invoices/receipts, platform statements, shipping/export evidence, bank and payment gateway records for five years. Good records support income tax reporting and GST treatments (standard-rated vs zero-rated) and reduce audit risk.
