Tonga Capital Gains Tax Guide: No CGT, Gains as Ordinary Income 2026
Tonga does not impose a separate capital gains tax. Capital gains from the sale of assets are generally treated as ordinary income and taxed at progressive PIT rates (10-20%) for individuals or CIT (25%) for companies. There are no specific CGT exemptions or holding period rules. Here is how capital gains are taxed in 2026.
Capital gains taxation in Tonga is governed by the Income Tax Act 2007. Unlike many countries that maintain a separate capital gains tax regime with preferential rates, Tonga treats most capital gains as ordinary income. This means gains from property sales, share disposals, and asset sales are included in the taxpayer's assessable income and taxed at standard rates. Property tax guide →
Real-world example: An individual sells a piece of land in Tongatapu for TOP 200,000, originally purchased for TOP 150,000. Gain: TOP 50,000. This is added to their other income and taxed at progressive PIT rates. If their total income is TOP 80,000: PIT = 10% on first TOP 30,000 + 20% on TOP 50,000 = TOP 3,000 + TOP 10,000 = TOP 13,000. Effective rate on the gain alone would be approximately 14%. A company selling the same asset would pay CIT at 25% on the TOP 50,000 gain = TOP 12,500. Corporate tax rates →
Taxation of Capital Gains
- No separate CGT: Tonga does not have a standalone capital gains tax regime
- Real estate gains: Treated as ordinary income — taxed at progressive PIT rates (10-20%) for individuals or CIT (25%) for companies

Calculating the Gain
The taxable gain is calculated as:
- Sale price: The price received on disposal
- Minus cost basis: The original purchase price plus allowable costs (acquisition costs, improvements)
- Equals gain: Included in assessable income
If the sale price is lower than the cost basis, a capital loss arises. Capital losses may be offset against capital gains in the same year or carried forward (subject to limitations).
Exemptions and Reliefs
- Primary residence: Gains from the sale of a primary residence may be exempt under specific conditions
- Personal assets: Gains from the sale of personal use assets (vehicles, household goods) are generally not taxable
Exemptions require documentation and may need confirmation from the TRC.

Yes. Non-residents selling Tongan real estate or other Tongan assets are subject to tax on the gain at standard PIT or CIT rates. The buyer may be required to withhold tax at the time of sale.
How are capital gains collected?
For real estate transactions, the gain is declared in the annual tax return. For certain transactions, the TRC may require withholding at source. Capital gains on shares are reported through the annual filing process.
