IRS Exchange Rates: Which Rate Goes on Which Form?

Freelancer counting U.S. dollars beside a laptop and charts, reflecting the currency conversions often needed when using IRS exchange rates.

There’s no single IRS exchange rate for every expat tax situation. The right rate depends on what you’re reporting: regular income, a foreign account, an asset sale, or foreign taxes.

At Bright!Tax, we help U.S. expats get those conversions right. Here’s when to use an annual average, a transaction-date rate, or a year-end rate—and why they aren’t interchangeable.

📋 Key Updates for 2026

  • For 2025 returns filed in 2026, the IRS annual-average pound rate changes from £0.783 to £0.759 per U.S. dollar.
  • The IRS annual-average euro rate for 2025 returns changes from €0.924 to €0.886 per U.S. dollar.
  • For tax year 2026, the Foreign Earned Income Exclusion increases to $132,900.

What are IRS exchange rates?

“IRS exchange rates” is a useful search term, but the Internal Revenue Service does not prescribe one universal official rate for every U.S. tax situation.

Instead, the conversion rule depends on what taxpayers are reporting on their U.S. tax return or information return.

What you’re reportingWhy the conversion method matters
Foreign salaryA reasonable annual average can suit regular payments
A one-time bonusThe receipt-date rate captures that particular payment
A foreign financial accountReporting rules specify the value and conversion date
A property or investment salePurchase, sale, and basis adjustments can require different historical rates
Foreign taxes paidPaid-basis and accrued-basis credit claims follow different rules
A foreign tax refundThe refund-date rate is not automatically the correct rate

The IRS’s yearly average currency exchange rates can be useful for recurring income. They are not a shortcut for converting every number on your return.

The starting point is the applicable rule. Consistency and good records support that rule; they don’t replace it.

What is a spot rate?

A spot rate is the exchange rate prevailing at a particular time. For many individual income-tax items, the starting rule is to use the rate when the item is received, paid, or accrued.

Daily exchange rates can help establish a historical transaction-date rate. Annual averages serve a different purpose: representing appropriate recurring amounts over a year.

💡 Pro Tip:

Before searching for an “IRS foreign exchange rate,” identify the form and the item. “Which rate applies to this salary?” is a more useful question than “What’s the IRS rate for euros?”

Why exchange rates matter for U.S. expats

Your financial life may happen in pounds, euros, yen, or pesos. Your individual U.S. tax return reports amounts in dollars.

U.S. citizens and resident aliens report taxable worldwide income on required returns. That means foreign salary, rental income, pensions, interest, dividends, and other income need the appropriate dollar calculation.

Currency exchange rates can affect:

For our Bright!Tax clients, the biggest differences often arise around property sales, investments, and foreign tax payments. A local tax return may show the correct result under local rules without supplying the correct dollar figures for the U.S. return.

There’s also a difference between a reporting conversion and actually exchanging money. You can have a dollar amount to report even if you never converted the foreign currency into dollars.

Which exchange rate should you use?

The exchange rate needs to match the income, transaction, or reporting requirement.

What you’re reportingConversion starting point
Regular salary or pension payments throughout the yearPayment-date rates, or an annual average that reasonably represents the receipts
One-time bonus or lump-sum receiptReceipt-date rate for a cash-basis taxpayer
Freelance or business incomeReceipt/accrual rules, with reasonable averaging where appropriate and separate rules for some businesses
Foreign rental incomeReceipt-date rates or a reasonable representative average
Foreign taxes claimed on a paid basisPayment-date or withholding-date rate
Foreign taxes claimed on an accrued basisUsually the average for the year to which the taxes relate, subject to exceptions
FBAR account valuesCalendar-year-end Treasury rate applied to each account’s maximum foreign-currency value
Form 8938 asset valuesUsually the tax-year-end Treasury rate, subject to the form’s exceptions
An ordinary purchased asset sold laterRelevant historical rates for acquisition, disposal, and basis adjustments
Earlier-year returnsRates appropriate to that earlier year or transaction

These are starting points, not permission to choose whichever method produces the smallest number.

A note for business owners and QBUs

Some qualified business units (QBUs) use a foreign functional currency under separate rules. A QBU is a separate, clearly identified business unit that maintains its own books and records.

If your business falls into that category, translating every receipt as though it were personal salary may be the wrong approach. The IRS guidance on foreign currency and currency exchange rates, within its international-taxpayers resources, explains the functional-currency starting rules.

When an annual average makes sense

A yearly average can reasonably represent income received regularly throughout the year.

For example, suppose Claire, a U.S. citizen in the U.K., received a £60,000 salary in equal monthly payments throughout 2025. Using the IRS’s 2025 average of £0.759 per $1, the conversion is:

CalculationAmount
Salary received£60,000
Foreign-currency units per dollar0.759
Dollar calculation£60,000 ÷ 0.759
Salary expressed in dollarsApproximately $79,051

Before using that approach, we would check whether the average reasonably represents her receipts. A salary earned during only part of the year, or payments concentrated around a sharp currency movement, deserves closer attention.

When to use a transaction-date rate

A one-time receipt or asset transaction needs a rate connected to the relevant event.

If Kenji, a U.S. citizen in Japan, receives a substantial bonus in November, we would look at the receipt-date conversion rather than automatically applying the same annual average used for his regular salary.

Likewise, if he sells investments and converts the proceeds into dollars three months later, that later bank conversion does not replace the rate required for the investment disposal. Holding and later disposing of the currency can raise a separate tax question.

💡 Pro Tip:

Keep both the event date and any later currency-conversion date. A sale, a payment, and a transfer between accounts are not necessarily the same tax event.

How to read exchange-rate tables without reversing the calculation

Check which way the rate is quoted before reaching for the calculator.

The IRS annual-average table lists foreign-currency units per U.S. dollar. To convert a foreign amount into dollars, divide by the listed rate.

Other sources may quote dollars per unit of foreign currency. In that case, multiply.

Rate quotationConversion into dollars
£0.759 per $1Divide the pound amount by 0.759
$1.25 per £1Multiply the pound amount by 1.25
¥150 per $1Divide the yen amount by 150
$0.006667 per ¥1Multiply the yen amount by 0.006667

The last three rates illustrate quotation formats; they are not prescribed rates for a particular reporting date.

Reversing the calculation can turn an otherwise careful return into a very expensive calculator mistake.

Exchange rates for FBAR, FATCA, and foreign asset reporting

Foreign account reporting has its own rules. Start by separating FBAR from Form 8938.

RequirementWhat it coversValue and conversion method
FBAR / FinCEN Form 114Reportable foreign financial accountsDetermine each account’s maximum value in its currency, then convert using the calendar-year-end Treasury rate
Form 8938 under FATCASpecified foreign financial assetsReport maximum annual values under the form’s valuation rules, usually converted using the tax-year-end Treasury rate
Income-tax reportingIncome, deductions, taxes, and transactionsApply the conversion rule for the particular item

FBAR: maximum value, year-end exchange rate

A U.S. person with the relevant financial interest or signature authority must assess FBAR when the aggregate value of reportable foreign accounts exceeds $10,000 at any time during the calendar year, subject to exceptions.

For each reportable account:

  1. Determine its maximum value during the year in the account’s currency.
  2. Convert that value using the Treasury reporting rate of exchange for the final day of the calendar year.
  3. If Treasury provides no rate, use another verifiable rate and identify the source.

The maximum balance and the exchange rate therefore come from different points in time.

For example, suppose Elena’s euro account reached a maximum of €25,000 in June but held only €4,000 at year-end. If the applicable year-end rate were €0.80 per dollar, the reported maximum would be:

€25,000 ÷ 0.80 = $31,250

We would not substitute the €4,000 closing balance or use June’s rate simply because the maximum occurred then.

FinCEN’s instructions allow periodic statements to establish the maximum if they fairly reflect the highest value.

Form 8938: don’t confuse the value with the rate date

FATCA/Form 8938 reporting covers specified foreign financial assets and accompanies your annual return.

The form reports maximum annual asset values under its valuation rules. Its thresholds consider values at year-end and at any time during the year.

For foreign-currency conversion, the Form 8938 instructions ordinarily require the Treasury rate from the final day of the tax year—even if you closed the account or disposed of the asset earlier.

If Treasury has no rate, use another publicly available rate and disclose the source. The instructions also allow reliance on certain financial-account statement conversion rates.

Your filing status and whether you qualify as living abroad affect the thresholds. And if you do not have to file an income-tax return, you do not have to file Form 8938, even above the asset threshold. A separate FBAR obligation can still apply.

What about Form 3520?

Foreign-currency amounts can also matter when assessing reportable foreign gifts or foreign-trust transactions on Form 3520.

This is a separate reporting requirement—not another name for FBAR or Form 8938. Follow the Form 3520 instructions for the transaction and valuation involved rather than automatically importing an account-reporting conversion method.

💡 Pro Tip:

Closing an account does not erase its reporting history. Include accounts closed during the year when collecting records for FBAR and Form 8938.

How exchange rates affect capital gains and foreign assets

The U.S. gain on a foreign asset can differ from the gain shown in local currency.

For an ordinary purchased asset, calculate dollar proceeds and dollar basis separately. Don’t simply calculate the local gain and translate that one number.

A property-sale example

Suppose Marcus, a U.S. citizen living in Canada, buys an investment property for C$300,000 and later sells it for C$400,000.

Assume these transaction-date rates:

ItemCanadian-dollar amountRateDollar amount
Purchase priceC$300,000C$1.20 per $1$250,000
Sale proceedsC$400,000C$1.40 per $1Approximately $285,714
Difference before other adjustmentsC$100,000Calculated separately in dollarsApproximately $35,714

Converting the C$100,000 local gain at the sale-date rate would produce approximately $71,429—a different answer.

This simplified example excludes improvements, transaction costs, depreciation, and other adjustments. A complete property-sale calculation must include the relevant items using their appropriate historical rates.

Purchase price isn’t always your basis

CircumstanceWhat needs attention
Purchased investmentAcquisition cost and subsequent basis adjustments
Rental or business propertyImprovements, depreciation, and other adjustments
Inherited assetsOften fair market value at death, subject to exceptions
Gifted assetsSpecial gift-basis rules
Assets bought before moving abroadHistorical basis does not automatically reset when you move

For our Bright!Tax clients selling long-held assets, old purchase and improvement records can be just as important as the current sale statement.

I wouldn’t start with the local tax return’s final gain and assume the U.S. number follows from it. The dollar calculation needs to be built from the underlying records.

Which exchange rate applies to foreign taxes and refunds?

Foreign tax credit reporting has specific conversion rules. “Use the payment date” is not the complete answer for every claim.

SituationConversion rule
Claiming taxes on a paid basisRate when paid or withheld
Claiming taxes on an accrued basisUsually the average for the tax year to which the taxes relate
Accrued taxes falling within an exceptionApply the specific rule, which may require payment-date conversion
Refund of taxes previously claimed on a paid basisOriginal payment-date rate, not the refund-date rate

The Form 1116 instructions identify exceptions to the accrued-tax average rule, including certain early or late payments and inflationary currencies.

A foreign tax refund example

Suppose Priya paid £8,000 of foreign income tax and claimed it on a paid basis. At the payment date, the rate was $1.25 per pound, giving a $10,000 dollar amount.

She later receives a £2,000 refund when the rate is $1.35 per pound.

For the paid-basis foreign tax credit adjustment, the refund converts at the original rate:

£2,000 × $1.25 = $2,500

It is not translated as $2,700 merely because that is its dollar value at the refund date.

The refund can also require a foreign tax redetermination. Keep the original payment records and the refund notice together so the earlier credit can be reviewed correctly.

💡 Pro Tip:

Tell your preparer about foreign tax refunds even when they relate to an earlier year. The relevant U.S. adjustment may reach back to the credit originally claimed.

Where to find exchange rates for IRS tax reporting

Use the reporting rule to choose the source—not the other way around.

SourceUseful for
IRS yearly average currency exchange ratesAppropriate recurring-income conversions
Treasury Reporting Rates of ExchangeRequired year-end conversions for FBAR and, ordinarily, Form 8938
Federal Reserve H.10 dataHistorical daily exchange rates for covered currencies
Bank and broker recordsEvidence of transaction dates, amounts, and relevant rates
Payroll and pension recordsEstablishing when and how much income was received
OANDA or XEHistorical posted rates where appropriate

The Federal Reserve publishes daily bilateral exchange-rate observations in its H.10 releases. The Federal Reserve Bank of St. Louis also provides access to exchange-rate series through its FRED database.

These are useful sources, but a Federal Reserve rate does not replace a prescribed Treasury rate for a form that requires one.

The IRS also lists OANDA and XE among its external currency resources. Where source selection is permitted, choose a suitable posted exchange rate, apply it consistently, and keep the supporting record.

Treasury now directs users to Fiscal Data for its reporting-rate dataset and converter. These reporting rates should not be mistaken for a daily market-rate service.

Which year’s rates should you use?

Match the rate to the reporting year or transaction.

As of November 3, 2026, the IRS annual-average table runs through 2025. A completed 2026 annual average and the December 31, 2026 reporting rate are not yet available.

Work you’re completingAppropriate approach
A 2025 return filed during 2026Use the applicable 2025 or historical transaction rates
A 2026 transaction-date calculationUse the relevant 2026 transaction date
Planning for the full 2026 yearUse clearly identified estimates where necessary
Final 2026 year-end account conversionUse the prescribed December 31, 2026 rate once available
Catching up on back taxesUse the rules and historical rates for each reporting period

The latest published annual average is not automatically the correct rate for the year you are preparing.

What records should you keep?

RecordWhat to save
Underlying amountOriginal currency and amount
Relevant dateReceipt, payment, acquisition, sale, or reporting date
Rate sourceDownloaded table, statement, screenshot, or other reliable record
Rate quotationWhether it shows foreign units per dollar or dollars per foreign unit
CalculationThe conversion and any rounding
Reporting purposeThe form or tax item to which it applies

For multiple-rate currencies, document why the chosen rate applies to your circumstances.

Can exchanging currency itself create taxable income?

An exchange rate is not a tax rate. But disposing of foreign currency can create a separate gain or loss.

Business, investment, and foreign-currency debt transactions can fall under section 988 or other applicable rules. Repaying a foreign-currency loan, for example, deserves a separate review from the property or investment it financed.

For a qualifying personal disposition of foreign currency, exchange-rate gain is excluded if it does not exceed $200. If the gain exceeds $200, that exclusion does not apply—it is not an annual $200 deduction.

The section 988 rules distinguish personal transactions from business and investment arrangements. Don’t assume that every movement between currencies is taxable, or that currency gains never matter.

When to get help with IRS exchange rates

A regular salary and clear records may make conversion straightforward. Other situations need more attention.

Consider a review when you have:

  • A foreign property or investment sale.
  • Multiple currencies or exchange-rate systems.
  • Foreign business income or functional-currency questions.
  • Accrued foreign tax credits or tax refunds.
  • Foreign pensions and investments.
  • FBAR, Form 8938, or Form 3520 reporting.
  • Earlier-year returns or Streamlined Filing Compliance Procedures.
  • Foreign-currency loans or potentially taxable currency gains.

The challenge is often deciding which rule applies before doing the arithmetic. Once that is clear, the conversion itself becomes much easier to explain and document.

Frequently Asked Questions

What exchange rate should I use for the IRS?

There is no single IRS exchange rate for every situation. The right rate depends on what you are reporting, whether that is income, a foreign bank account, foreign taxes paid, or a capital gain. In general, use a reasonable posted rate, apply it consistently, and keep a record of the source.

Does the IRS have an official exchange rate?

Not one universal rate for every tax situation. The IRS provides yearly average exchange rates on IRS.gov, but taxpayers may also use other reliable posted rates when appropriate. For official guidance, use the IRS official website or another trusted gov website, not a random currency page with suspicious pop-ups and strong opinions.

Can I use the IRS yearly average exchange rate?

Often, yes, especially for regular income received throughout the year, such as salary or pension income. But an average rate may not be right for a one-time payment, property sale, investment sale, or foreign tax payment tied to a specific date.

Which exchange rate should I use for FBAR?

For FBAR, you generally report the maximum value of your foreign financial accounts during the year and convert that value into U.S. dollars using the year-end Treasury rate when available. This is different from reporting income on your tax return, because FBAR is focused on account value, not taxable income.

Are FBAR and Form 8938 the same thing?

No. FBAR and Form 8938 are separate filing requirements. FBAR is filed through FinCEN and focuses on foreign financial accounts, while Form 8938 is attached to your tax return and is linked to FATCA reporting rules. Depending on your accounts, assets, filing status, and dollar amount, you may need one, both, or neither.

How do I report income earned in a foreign country?

You generally convert the foreign income into U.S. dollars before reporting it on your U.S. tax return. This can apply to salary, freelance income, rental income, pension payments, dividends, interest, and self-employed income earned abroad. The exchange rate should match the timing and type of income you are reporting.

Is there a tax rate for currency exchange?

Not exactly. The exchange rate is not the tax rate. Currency exchange rates convert foreign amounts into U.S. dollars; after that, the usual U.S. tax rules decide what happens next.

Simply exchanging money for personal use is not always taxable. But foreign currency gains and losses can matter in some business, investment, debt, or foreign-loan situations, so a small business owner, investor, or expat with foreign loans should speak with a CPA before assuming currency movement is irrelevant.

Where can I find historical exchange rates for previous years?

You can use IRS yearly average tables, Treasury rates, bank or broker records, payroll statements, pension records, or reputable historical exchange-rate sources such as OANDA or XE. The best source depends on what you are reporting and whether you need an annual average, year-end rate, or transaction-date rate.

Do exchange rates affect foreign tax credits?

Yes. If you paid tax to a foreign country, that amount usually needs to be converted into U.S. dollars before it can be used on your U.S. return. The timing can matter, especially if the tax was paid in a different year from when the income was earned.

Should I ask a CPA about IRS exchange rates?

It depends on the size and complexity of the return. If you have regular salary income and clear records, the exchange-rate work may be straightforward. But if you are self-employed, selling foreign property, reporting a large foreign account, filing for previous years, claiming foreign tax credits, or dealing with multiple currencies, a CPA who understands expat tax, such as our experts at Bright!Tax, can help make sure the numbers hold together.
