A rough guide to paying taxes in Portugal for US immigrants
First the critical disclaimer
If you only read one thing on this web page, make it this section. This is 100% not tax advice. This is meant to help people understand what they might pay in taxes in Portugal, and highlight a few of the many things people need to consider. By design, this is an over-simplification. Taxes are complicated. The important details that will determine your specific tax situation would make this explanation extremely complicated, so I’ve intentionally simplified things to paint a broad picture. You need to work with a qualified Portuguese tax professional to understand your actual situation. So do not take this as tax advice, but rather a simplified tool to help you understand some important tax concepts.
Who is this for?
This article, and the tax estimator tool are intended for US citizens who have immigrated to Portugal, or plan to do so in the near future. US citizens face some very unique circumstances. First, the US is (for all practical purposes) the only country with citizenship-based taxation. Eritrea has a form of this, but only the US applies it broadly. This is a critical concept to understand, and important to keep in mind when looking for a Portuguese tax professional. No other immigrant population in Portugal is subject to income tax in 2 countries. This makes the US-Portugal Tax Treaty unique, too.
The other complicating factor is the incredibly complex number of options the US has for retirement funding. The traditional pension, still the dominant option in most developed economies, has largely faded away in the US, replaced with individual savings options with unique tax advantages, such as the IRA, 401(k), and Roth IRA. This presents some challenges when aligning US retirement income to Portuguese income categories. Yet another reason to consult with a qualified Portuguese tax person.
Why write this guide?
I frequently see people struggle to understand how taxes work in Portugal, especially Americans who are used to the US system. For many people considering moving to Portugal, understanding your tax obligations will be one of the more important parts of your plan. We all know that the income tax burden in the US is fairly low, and that EU countries, including Portugal, have higher taxes on income. Some people see the top-end 48% bracket and lose their minds. “I can’t afford to pay half my income in tax!” For others, the taxes here are even less defined; some amorphous blob of risk. Unknown, but it has to be bad, right?
So, taxes will be higher here in Portugal. No escaping that. But how much higher? Hopefully, the estimator below can help you understand that a bit more clearly. No one will ever hand over half of their income to the Portuguese tax authorities. I see far too many people think that’s the case, but that just isn’t how graduated income taxes work. Hopefully, this will help people get a better understanding of what they might face in Portugal, and be able to work better with their Portuguese tax person.
Other things to consider before diving in
Everything is in Euros. You will need to convert USD to EUR before starting this. Portugal taxes all of your worldwide income. Yes, there are some limited and narrowly-defined exceptions, but for purposes of estimating, a reasonable person should assume that every income source is subject to income tax in Portugal unless your Portuguese accountant or tax attorney specifically says otherwise. Yes, that even includes freelance clients in other countries. No, that LLC you set up last month likely won’t change this.
The big one: a couple vs. single taxpayer. This is a big difference with the US system. In the US, the threshold for each tax bracket essentially doubles for couples. In the US, the 22% tax bracket starts at $48,476 for a single person, or twice that, $96,951, for a couple filing jointly.
Portugal takes a different approach that roughly achieves the same thing, but if you are not specifically aware of this approach, you can reach wildly incorrect conclusions. In Portugal, for a married couple, the household income is split in half, and taxes are calculated for each person’s half, then the resulting tax obligation is added back together. For a couple with €60,000 in household income, that means almost all of their income is taxed at 31.1% or lower, and none of the income would get taxed at 44.6%. The estimator tool below specifically shows that.
There are a lot of factors that impact how this plays out, and this estimator tool has simplified the calculations to help illustrate the broader point. So, once again, consult a qualified Portuguese tax professional to understand your situation.

How your income fills the tax brackets
The same income, taxed as a single person and as a couple. A couple's income is split in two, and each half climbs the brackets on its own.
- 12.5%

- 21.2%
- 24.1%
- 31.1%
- 34.9%
- 43.1%
- 44.6%

How the calculation works
The calculator follows four steps:
- Add up all income. Every income type adds to one total.
- Subtract deductions. Salary income and pension income (which includes Social Security and IRA/401(k) withdrawals here) each get a fixed deduction. Only 75% of self-employment income is taxed under the simplified regime.
- Split in two for couples. When a couple files jointly, taxable income is divided by two and each half is taxed separately using the brackets below.
- Fill the brackets. Each slice of income is taxed at its bracket's rate. The effective rate is total tax divided by total income.

| €0 – €8,342 | 12.5% |
| €8,342 – €12,587 | 15.7% |
| €12,587 – €17,838 | 21.2% |

What this doesn't cover
- Rates are for continental Portugal. Madeira and the Azores have their own rates.
- Tax credits (personal, dependents, health, education) aren't included. They would lower the tax shown.
- For couples, the calculator assumes the checkbox setting for whether both partners get their own salary or pension deduction.
- US Social Security is included as pension income. How it's actually taxed depends on the US–Portugal tax treaty and your citizenship.
Additional considerations
There are other types of income that is taxed differently, and typically will NOT impact your income tax calculations
- Capital gains tax, both for the sale of real property and for securities
- There are a LOT of options for calculating capital gains, well beyond the scope of this estimator too. At some point, I'll try to share some more information on capital gains taxes in Portugal, which are typically 28%. But what you actually pay will depend on many factors. Which is why (say it with me now...) you need to consult a qualified Portuguese tax professional.
- Dividend and interest income - also very complex. Can be taxed at 28%, or as regular income. For estimating purposes, you could treat it as regular income. But, if you rely heavily on dividends in your retirement portfolio, (say it with me now...) you should consult a qualified Portuguese tax professional to determine the best way to handle dividends.
- Rental income - also excluded from the estimator, and it can be taxed at a flat rate of either 25% or 28%. To be honest, I'm not sure. I don't have rental income, so I've never really bothered to check. If you have rental income.... by now you should know what to do.
Some things to look for in a Portuguese accountant
The US-Portugal tax treaty
By now, hopefully, you are well-aware of the unique tax situation faced by US citizens who've immigrated to Portugal. Because we remain subject to tax in the US, our situation is unique. The tax treaty has to account for a lot, and the impact of our "dual" tax obligations must always be accounted for by anyone working on our taxes. You could read it yourself, you can download the US-Portugal tax treaty as a PDF from the Internal Revenue Service website. More importantly, though, you need to find a tax professional who has significant experience and understanding of the tax treaty and how it can shape your tax obligations in Portugal.
Portuguese income categories
Portugal taxes income in 6 categories, shown below. When you bring income from the US, you need to figure out how to map that income to one of these 6 categories. Sometimes it is pretty simple; freelance income maps to Category B, for example.
| Category | Description | Common examples |
|---|---|---|
| Category A | Employment income (Trabalho Dependente) |
|
| Category B | Business & professional income (Trabalho Independente) |
|
| Category E | Investment income (Rendimentos de Capitais) |
|
| Category F | Rental income (Rendimentos Prediais) |
|
| Category G | Capital gains & asset increases (Mais-valias) |
|
| Category H | Pensions (Pensões) |
|
But US retirement income can be pretty tricky. Portugal doesn't have 401(k) or IRA accounts. Generally, they would map to Category H, pension income. But, if you take a lump-sum withdrawal, that could be seen as Category G. When trying to map US income sources to Portuguese income categories, the guidance can often be unclear or ambiguous.
The CIRS, which stands for Código do Imposto sobre o Rendimento das Pessoas Singulares(the Personal Income Tax Code) has rules and guidelines. The tax treaty also shapes how this works. But in some cases, that isn't enough. Sometimes, this could go to court or an arbitration hearing to get specific guidance. Again, another great reason to work with a Portuguese tax professional, so you can have someone who knows the system guide you through it. Even then, there can be disagreements and different interpretations of the tax code and tax treaty, without much clear guidance until a court/arbitration case settles things. Based on my research, I think Roth IRAs fall into this category. I've seen differing views on the tax treatment of Roth IRA withdrawals, and so far, I've not seen anything I'd consider "definitive" on what to expect.
