How Portuguese Banks Assess Your US Income
Dollar income is accepted. Here is what banks actually look at.
“Will a Portuguese bank accept my dollar income?” is the first question most American buyers ask us. The short answer is yes. Income in US dollars is accepted, as long as it is documented and consistent.
The longer answer is that a bank reads a dollar income differently from a euro income. Not because dollars are a problem, but because the mortgage will be in euros. That single fact shapes how your file is analyzed.
The three questions behind every analysis
When a credit analyst opens a file with US income, the questions are always the same:
- Is this income stable? Will it still be there in 10, 20, 30 years?
- Can it be proven and traced? Can the bank verify it with documents it understands?
- Is it exposed to currency risk? What happens to the payment if the dollar moves?
The third question is the one that is specific to you. Let’s start there.
1. Currency risk, in plain terms
Your Portuguese mortgage will be paid in euros. Your income is in dollars. If the dollar weakens against the euro, the same monthly payment costs you more dollars. The loan didn’t change. Your purchasing power did.
A simple illustration (the exchange rates are hypothetical):
- Monthly payment: €1,500
- When €1 = $1.10, you pay about $1,650 a month
- When €1 = $1.25, you pay about $1,875 a month
Same loan, $225 more per month, and your salary hasn’t moved.
The bank carries this risk too, because a borrower under pressure is a borrower who may struggle to repay. That is why banks tend to read dollar income more conservatively than euro income. There is no single published formula, and the method varies from bank to bank. Depending on the bank and your profile, the caution can show up in several ways: a more prudent conversion of your income into euros, a lower share of the purchase price financed, or a more careful look at your savings and reserves.
Some banks also state this risk openly in their own materials: if you live outside the euro area, exchange rate movements can increase the amount you pay in euros.
2. Stability: what banks want to see
Banks are looking for income that is regular, recurring and likely to continue. Here is how different US income profiles are typically read:
| Your income | How a bank typically reads it |
|---|---|
| Salaried (W-2), permanent position | The easiest profile. Recent payslips, employer letter, tax return. Seniority in the job helps. |
| Salaried with bonus, commission or stock compensation | The base salary is the solid part. Variable pay is usually looked at over a track record (often two years) and may only be partly counted. |
| Self-employed, business owner, 1099 | Analyzed over several years of tax returns and profit & loss statements. Steady or growing income reads well. Irregular income is harder. |
| Retired (pension, Social Security) | Stable and predictable. Documented with benefit statements and tax returns. |
| Rental or investment income | Often considered, but treated with more caution and documented with leases, statements and tax returns. |
Two details matter more than people expect:
- Net, not gross. The Banco de Portugal framework measures income net of taxes and mandatory social contributions. Your US payslips and returns will be read with that in mind.
- A US tax return can look complicated to a system built around the Portuguese one. A clear, well-organized file, and sometimes a short summary of how your income is made up, makes the analyst’s job easier. That is part of what a broker does.
3. The ratio that decides everything: your debt-to-income
Since August 1, 2026, the Banco de Portugal recommends that your total monthly debt payments (the new mortgage plus every existing loan) stay below 45% of your net monthly income. The limit was 50% before. Banks have limited room to go above it, and some work with a stricter internal limit for non-resident profiles.
The bank also tests your file against a higher interest rate, to check that you could still pay if rates rose.
A simple illustration (hypothetical exchange rate of €1 = $1.20):
- Net income: $6,000 a month, about €5,000
- 45% cap: €2,250 of total monthly payments
- Existing car loan: €300
- Room left for the mortgage payment: about €1,950
Everything is calculated in euros, and existing debts count, even when they are in the US. This is why a more conservative exchange rate in the bank’s calculation directly reduces how much you can borrow.
4. The down payment: where currency risk really shows up
For non-residents, banks typically finance a lower share of the property than for residents. Depending on the bank, your residency and your profile, the financing level is often somewhere between 60% and 80% of the property value, which means a down payment of roughly 20% to 40%. Buyers earning outside the euro area tend to sit nearer the cautious end of the range.
The down payment is your best lever. A larger one reduces the loan, which reduces the monthly payment, which reduces both your debt ratio and your exposure to the dollar.
5. How to strengthen a file with dollar income
- Show stability early. Employer letter, tenure, contract type. If part of your pay is variable, be ready to show it over two or more years.
- Keep your documents consistent and current. Statements that are too old, or names that differ from one document to another, slow files down.
- Bring a larger down payment if you can. It is the single most effective way to offset currency risk.
- Keep a euro reserve. Holding part of your savings in euros, ideally in a Portuguese account, shows the bank you can absorb a bad exchange-rate period.
- Open your Portuguese bank account early. You will need one anyway to pay your installments, and it lets you build a track record of dollar-to-euro transfers.
- Settle or reduce your existing debts before applying. They come straight out of your 45%.
- Plan your own buffer. Even when the bank approves, budget a margin of around 10% on your monthly payment for exchange-rate swings. This is your own risk management, not a bank requirement.
6. Common mistakes
- Assuming dollar income is a problem. It isn’t. It is simply analyzed with more care.
- Underestimating existing US debts, which count in the ratio.
- Stretching to the maximum payment the bank allows, with no margin if the dollar weakens.
- Applying with variable or irregular income that isn’t documented the way a Portuguese bank expects.
- Moving large sums right before applying without being able to explain where they came from.
7. How a broker helps
Each bank reads dollar income a little differently. Some are more comfortable with US tax returns, some are more flexible on variable pay, some offer a better financing level for non-euro profiles. A broker knows which bank fits your profile, presents your income the way the analyst expects to see it, and checks the file for gaps before it reaches the bank. The service is free for the borrower in Portugal: the broker is paid by the bank.
In summary
- ✔ Dollar income is accepted when it is stable and documented
- ✔ The mortgage is in euros, so banks read dollar income with extra caution
- ✔ Your total monthly debt payments are capped at 45% of net income, all debts included
- ✔ A larger down payment and a euro reserve are your best tools
- ✔ The right bank for your profile makes a real difference
