Foreign income for a mortgage is pay from a foreign employer or government, in a foreign currency, and lenders verify it mainly through the borrower's US federal tax returns. The amount is converted to US dollars, often with a cushion for exchange-rate swings. Overseas deposits on bank statements then confirm the pay still arrives and matches what the returns report.
What counts as foreign income for a mortgage?
Foreign income is pay earned from a foreign corporation or a foreign government and paid in a foreign currency. That is the definition used in agency guidance, and most lenders share it. Pay that only travels through a foreign bank, or a US salary earned while living abroad, is a different case and is verified like any other wage.
The Fannie Mae Selling Guide section on standards for employment-related income uses that definition and sets two conditions: the borrower provides signed federal income tax returns for the most recent two years that include the foreign employment income, and all income is converted to US dollars.
Cases that sit near the line
- A US citizen paid in pounds by a UK company. Foreign income.
- A US employee seconded to Singapore, still paid in dollars by the US employer. Not foreign income. It is ordinary salary.
- A consultant invoicing a German client from the US. Self-employment income, paid from abroad. The self-employed rules apply, with the currency step added.
- A pension from a foreign government. A retirement benefit, verified under pension rules, then converted.
The sorting matters because it picks the rulebook. Getting the category right first saves a second round of document requests.
Tax returns that report the foreign employment income
US federal tax returns are the anchor document for foreign income, because they show what the borrower declared to the IRS across two full years. Overseas payslips and employer letters support the returns but cannot replace them on an agency loan. A borrower who has not filed US returns that show the income will usually not qualify on it.
What to read on the returns
- Find the foreign wages, which usually appear on the wage line and sometimes on supporting forms for foreign earned income.
- Compare year one with year two. A drop needs an explanation, just as it would for domestic pay.
- Check that the employer named in the file matches the employer behind the reported wages.
- Note any foreign tax paid. It does not change gross income, but it explains why deposits are lower than the returns suggest.
A borrower who claimed an exclusion for foreign earnings still lists them on the return, so the wages are visible. Lenders differ on how they treat excluded pay when they calculate qualifying income, so ask the lender before quoting a figure.
Non-agency lenders sometimes accept foreign income without two years of US returns, often with an employer letter, translated payslips and statements. Those programs price the extra risk, and each one sets its own document list.
Which exchange rate converts foreign income to US dollars?
The exchange rate is chosen by the lender or the loan investor, not the borrower. Lenders commonly use a published rate from a recognized source on a recent date, and some apply a cushion below the current rate so a weaker currency later does not break the debt ratio. Ask which source, which date and which cushion before running numbers.
Agency guidance requires conversion to dollars but leaves the method to lender policy, so practice varies. The same choice comes up when converting foreign account balances, covered in currency conversion on foreign account balances.
Worked example
The figures below are an example for a borrower paid a monthly salary of €6,000 by a company in Ireland. Assume a spot rate of 1.08 dollars per euro and a lender that applies a 5 percent cushion.
| Line | Example figure |
|---|---|
| Monthly salary, euros | €6,000 |
| Spot rate, dollars per euro | 1.08 |
| Salary at spot rate | $6,480 |
| Rate after 5% cushion | 1.026 |
| Qualifying salary at cushioned rate | $6,156 |
| Average monthly net deposit into US account, last 3 months | $4,390 |
| Euro amount sent each month, converted at that month's rate before fees | $4,410 to $4,470 |
The cushion takes $324 a month off the qualifying figure. The deposits are lower again because they are net of foreign income tax and social charges. That gap is expected; what matters is that each month's net deposit is consistent with the payslip for the same month.
Picking the date
A rate from a single day can be unusually high or low. Some lenders average the rate over several months to smooth that out. Whatever the method, write the source, date and rate into the file so a reviewer can rebuild the number.
Overseas salary deposits on the borrower's bank statements
Overseas salary reaches a borrower's statements in one of two ways: into a foreign account in the local currency, or by wire or transfer service into a US account in dollars. The lender reads both, because the foreign account shows the employer paying and the US account shows the money arriving where the mortgage payment will come from.
What the deposits should show
- The employer, every month. In the foreign account, the payroll credit should name the employer or its payroll agent.
- Regular transfers to the US. A borrower who moves a set amount each month leaves a pattern that is easy to follow.
- Fees and rate spreads. Wire fees and conversion margins explain why the dollar amount is slightly lower than a straight conversion.
A borrower paid into a foreign account must supply statements from that bank, often with a translation. Translation, verification of the foreign bank and the seasoning of wired funds are covered in the guide to foreign bank statements for mortgage files.
Cash that leaves a foreign account and arrives as cash in a US account breaks the trail. Lenders treat unexplained cash with the same suspicion as any cash-heavy file, a topic covered in cash business income verification for lenders.
How stable must foreign income be for a mortgage?
Foreign income must meet the same stability tests as domestic pay: a reliable history, normally two years, and a reasonable expectation that it continues. For foreign pay, lenders also weigh whether the borrower will keep the job after buying a US home, and whether the currency has been volatile enough to threaten the converted figure.
Questions that test stability
- Will the job continue after the move? A borrower buying a US primary residence while keeping an overseas job needs a remote work agreement or similar proof.
- Is the contract fixed term? A contract ending within a year or two weakens continuance.
- Has the currency moved sharply? A currency that lost a large share of its value against the dollar in the past two years makes even a cushioned figure uncertain.
- Is there a gap? A break in the foreign job inside the history needs the same written explanation a gap in domestic employment would.
Commission-heavy foreign pay adds a second layer, because the commission rules apply on top of the currency rules. The way variable commission pay is averaged is set out in real estate agent income verification for loans, and the same averaging logic carries over to other commission earners.
When foreign income should stay out of the qualifying figure
Foreign income should stay out of the qualifying figure when the borrower cannot show it on US tax returns for an agency loan, when the job will not survive the move, or when the deposits do not match the declared pay. In those cases, counting it creates a figure the file cannot defend at review.
Signals to leave it out
- No US returns showing the income. An agency loan cannot use it. A non-agency program may.
- An employer letter that limits remote work. The job may end when the borrower relocates.
- Deposits far below the payslip net. Points to a second account, a salary cut or a payslip that is not genuine.
- Pay in a currency the lender will not convert. Some lenders limit the currencies they accept.
A file that failed on the deposits
The following is an example. A borrower's returns show about $78,000 a year of foreign wages, and the employer letter confirms a salary at that level. The foreign account, though, shows payroll credits that dropped by a quarter four months ago. The borrower explains that the employer moved her to a four-day week. The returns describe last year; the deposits describe now. The lender recalculates on the reduced salary, and the file still qualifies at a lower loan amount. Counting the old figure would have meant a debt ratio built on pay that no longer exists.
A late surprise is the worst outcome. If a currency drop or a new employer letter arrives in the final week, the converted figure may need to be redone. That is one reason to run the foreign income again in the final checks before clear to close.
