Singapore is famous for having no capital gains tax, but that doesn’t mean all profits from selling assets are automatically tax-free. Under certain conditions, the Inland Revenue Authority of Singapore (IRAS) can treat your gains as income in nature — making them taxable. This guide explains when that happens, key IRAS criteria, and how you can plan to keep your gains tax-free.

📌 1. Capital Gains vs. Income in Singapore
By default, capital gains — profits from selling investments like shares, property, or collectibles — are not taxable in Singapore. However, if IRAS deems your gains to be of an income nature, they will be taxed as personal or business income.
📌 2. The IRAS “Badges of Trade” Test
IRAS uses several criteria (often called the badges of trade) to determine if your transactions amount to trading:
- Frequency of transactions – Regular buying and selling suggests trading activity.
- Holding period – Short-term ownership of assets points to profit-making intent.
- Nature of asset – Assets typically acquired for resale (e.g., development properties) may attract taxation.
- Method of financing – Use of short-term loans may indicate intent to flip quickly.
- Supplementary work – Renovating, marketing, or improving assets before sale can be a sign of trading.
- Business relationship – If your job or business relates to the asset, gains may be taxable.
📌 3. Examples of Taxable Capital Gains
| Scenario | Likely Tax Treatment |
|---|---|
| Buying and selling 10 properties in 2 years | Taxable as business income |
| Day trading stocks daily for profit | Taxable as trading income |
| Buying rare watches and reselling regularly | Taxable as business income |
| Selling your family home after 15 years | Tax-free capital gain |
📌 4. Special Case: Property Transactions
Even when capital gains from property are generally exempt, IRAS may tax your profits if:
- You buy multiple units and sell them quickly.
- Your property activity resembles a business.
- You actively market and develop properties for resale.
Additionally, Sellers’ Stamp Duty (SSD) applies if you sell certain properties within the prescribed holding period.
📌 5. Share & Investment Gains Becoming Taxable
Selling shares or crypto for a one-off gain is normally tax-free. However, your profits may be taxable if:
- You trade frequently with the intent to profit from short-term price changes.
- Your trading volume is high and systematic.
- You borrow funds to finance short-term trades.
💡 6. How to Keep Gains Tax-Free
- Hold investments for longer periods.
- Avoid frequent, high-volume trading unless you accept tax implications.
- Maintain clear records of your investment intent.
- Structure investment activity to appear as capital investment, not a trade.
📍 Final Thoughts
While Singapore’s no-capital-gains-tax policy benefits most investors, the income in nature rule is a key exception. If your investment activity resembles a business, your profits can be taxed. By understanding IRAS’s criteria and structuring your transactions wisely, you can maximise tax efficiency while staying compliant.
