Questions
Tonga capital gains tax questions
Does Tonga have a capital gains tax?
No. Section 11 of the Income Tax Act makes gross income the total of business income, employment income, property income and any other income, and the gain on a private capital asset is none of these. Whether you sell shares after a week or land after twenty years, the gain itself is not taxed.
When is a gain taxed?
When the asset is a business asset. Section 12(1)(c) makes the gain on disposing of a business asset business income, worked out as the consideration less the cost. The Act counts shares in a company, or an interest in a partnership or trust, as a business asset when they derive 50% or more of their value, directly or indirectly, from immovable property.
What rate applies to a taxed gain?

Not as a capital gain. Crypto held as a personal investment is a private capital asset like any other, and no provision of the Income Tax Act taxes the gain on one.

How the calculator works and is tested
Every rate, threshold and date on this page comes from 21 dated records covering 2021 to 2027. Each record names the page it was read from and the day it was retrieved. The site uses the record in force on the day and stops with an error when none is, instead of showing an estimate.
Every country has a calculation engine with its own test file of worked cases. Type checks, linting, unit tests and backend tests run on every change, and English page renders are compared with stored snapshots.
