Selling an asset in Singapore? Estimating capital gains tax

Published April 21, 2026 · 2 min read

How to estimate capital gains tax on shares, property or other assets sold in Singapore: gain, costs, rate and net proceeds.

Working out the gain

The taxable gain is usually the sale price minus the purchase price and allowable costs, such as broker fees, legal fees or improvement costs. If the result is negative, you have a loss, which may be offset against other gains depending on the rules in Singapore.

Worked example

Here is the calculation with sample figures. Change any number in the Singapore Capital Gains Tax Calculator to run your own.

Rates, allowances and holding periods

Many countries tax gains at a different rate from salary, offer an annual tax-free allowance, or reduce the rate for assets held longer. Some exempt a main home. Because these rules differ so widely, the calculator uses an editable rate that you can set from current guidance in Singapore.

Keep the paperwork

Keep purchase contracts, statements and receipts for costs. Without them, proving your cost basis can be difficult years later.

Quick reference at 9%

Common amounts in Singapore, worked both ways: adding tax to a net price, and extracting it from a price that already includes tax.

How Singapore compares

Standard rates on file for other countries. A difference of a few points matters most on high-value purchases and on cross-border sales.

Using the calculator step by step

1. Open the Singapore Capital Gains Tax Calculator.
2. Type your figures into the numbered lines. Results update as you type.
3. Check the rate field. It starts at 9%; change it if a reduced rate, local surcharge or exemption applies to you.
4. Read the result on the receipt panel, and use the formula shown under it if you need to explain the figure to a client or colleague.
