What Is Capital Gains Tax?

Capital Gains Tax (CGT) is a tax on the profit you make when you sell or dispose of an asset that has increased in value. It is the gain that is taxed — not the full sale price. The gain is the difference between what you paid for the asset (cost basis) and what you received when you sold it, minus any allowable costs.

Most countries apply different CGT rates depending on how long you held the asset (short-term vs long-term), the type of asset, and your overall income. Some countries — including Singapore, Hong Kong, and the UAE — charge no CGT at all, making them attractive for investors.

📅
Short-Term vs Long-Term In the US, assets held over 12 months qualify for preferential long-term rates (0%, 15%, or 20%). Short-term gains are taxed as ordinary income — as high as 37%.
🧾
Cost Basis Matters Your cost basis includes the original purchase price plus all allowable costs: brokerage fees, stamp duty, renovation costs for property, and legal fees. Higher cost basis = lower gain = lower tax.
📉
Losses Can Offset Gains Capital losses from other disposals can typically be used to offset capital gains in the same tax year, reducing your overall CGT bill. Unused losses may often be carried forward.

Why Calculating CGT Before You Sell Matters
01

Know Your Real Return

A 150% gain on paper may look impressive, but what matters is your after-tax return. CGT can significantly reduce net proceeds, particularly on short-term gains taxed as ordinary income.

✓ Investment Planning
02

Time Your Disposal Strategically

Waiting until you cross the 12-month threshold for long-term treatment can dramatically reduce your US tax rate — from up to 37% (short-term) to just 15% or 20% (long-term).

✓ Tax Efficiency
03

Maximise Cost Basis Deductions

Every allowable cost — brokerage, stamp duty, legal fees, renovation work — reduces your taxable gain. Correctly tracking your cost basis over years can save thousands in tax.

✓ Deduction Optimisation
04

Prepare for Your Tax Return

Having a clear CGT calculation ready makes tax filing faster and reduces errors. Export the detailed breakdown as CSV or PDF directly for your accountant or records.

✓ Compliance
05

Compare Cross-Country Tax Burden

Considering where to hold investments or relocate? Compare CGT across countries — from 0% in Singapore and Hong Kong to 30%+ in Sweden and France — and model the real impact.

✓ Global Strategy
06

Model Loss Harvesting

Use the calculator to understand how realising a capital loss can offset gains in the same year, reducing your overall CGT bill. A key strategy for managing year-end tax exposure.
