Foreign Currency to USD Converter (IRS Yearly Average Rates)

IRS yearly average exchange rates, 2020 to 2025 (full table)

Rates are expressed as foreign currency units per 1 US dollar, exactly as the IRS publishes them. To convert income to US dollars, divide the foreign amount by the rate for the tax year the income was earned.

Treasury year-end exchange rates for FBAR and Form 8938, 2020 to 2025

This is a different dataset from the IRS yearly averages above: the Treasury Reporting Rates of Exchange as of December 31 each year. Use these for account balances, meaning the FBAR (FinCEN Form 114) maximum account value and Form 8938, not for income. Six years are published deliberately: a Streamlined catch-up filing requires six years of FBARs, so a filer catching up in 2026 needs year-end rates back to 2020.

Which exchange rate do you use for a US expat tax return?

The IRS has no single official exchange rate. It accepts any posted rate that is used consistently, and for convenience it publishes a yearly average for each currency. In practice that yearly average is what most US expats use to convert a full year of foreign salary, self-employment, pension, or interest income into US dollars on Form 1040. That is what the converter above does.

Two situations use a different rate, and mixing them up is a common mistake:

• Account balances (FBAR and Form 8938): use the Treasury Reporting Rates of Exchange for December 31 of the year, not the yearly average. The FBAR reports the maximum value of each foreign account, converted at the year-end rate.
• A specific transaction (a property sale, a single large payment, a stock vesting): you may use the spot rate on the date of that transaction, which can be more accurate than a yearly average for a one-off event.

How the conversion works

The IRS publishes each rate as the number of foreign currency units that equal one US dollar. To convert foreign income to US dollars you divide by that rate; to go the other way you multiply. For example, 1,000,000 Japanese yen of 2024 income at the 2024 average of 151.353 yen per dollar is 1,000,000 divided by 151.353, or about 6,607 US dollars.

Frequently asked questions

What exchange rate does the IRS require for foreign income?

The IRS does not mandate one source. It accepts any exchange rate that is used consistently, and it publishes yearly average rates for convenience. Most expats convert annual foreign income using the IRS yearly average for the tax year.

Do I use the yearly average rate for the FBAR?

No. FBAR (FinCEN Form 114) and Form 8938 report account balances and use the Treasury Reporting Rates of Exchange for the last day of the year, not the IRS yearly average. The yearly average is for income.

What if my currency is not on the list?

The IRS publishes averages for the major currencies above. If yours is not listed, use another verifiable published rate (such as the Treasury rate or your country's central bank) applied consistently, and keep your source.

Which year's rate do I use?

Use the rate for the tax year the income was earned. Income earned in 2024 is converted at the 2024 yearly average, reported on your 2024 return.
