What is this calculator?
HMRC publishes official monthly exchange rates for converting foreign currency into Pound Sterling (GBP). You'll need these for a number of UK tax purposes: Self Assessment returns, foreign employment income, dividends, rental income, capital gains, VAT on foreign invoices, Inheritance Tax valuations and foreign currency entries in company accounts.
This tool automatically calculates the GBP equivalent of your foreign income using the exact HMRC Monthly Exchange Rate for the period your payment was received.
Our complete historical dataset supports conversions all the way back to January 2015.
If tax was deducted at source in the foreign country, enter the gross amount before any deduction, and record the withheld tax separately.
100% Private & Secure: All calculations happen directly on your device. None of your financial data, amounts, or descriptions are ever sent to a server or saved anywhere but your own browser.
