UK Capital Gains Tax on Mantle

HMRC treats MNT as a capital asset. Every time you sell, swap, or spend your Mantle, it's a taxable disposal. For the 2025/26 tax year, you have a £3,000 annual exempt amount. Gains above that are taxed at 10% for basic-rate taxpayers and 20% for higher-rate taxpayers. CryptoLens scans your on-chain history to calculate your exact liability using Section 104 pooling, with an optional HMRC-ready PDF export for paid members.

The Fumble Checker analyses your wallet for any MNTyou sold before it reached its all-time high. It compares your sell transactions against ATH prices and shows you the profit you left on the table. Share your fumble score on Twitter/X to compare with friends — it's become one of our most viral features.
