US Expat Taxes for Americans Living in Portugal – Everything You Need to Know

US Expat Taxes for Americans Living in Portugal

There are an estimated several thousand Americans living in Portugal.

Living in Portugal is an wonderful experience for many reasons, including the friendly locals, the climate, the beaches, and the quality of life. Many Americans have chosen to take advantage of Portugal’s Golden and D7 visas in recent years. As an American expatriate living in Portugal though, what exactly do you need to know regarding filing US expat (and Portuguese) taxes?

All US citizens and green card holders who earn more than $12,550 (in 2021, or just $400 of self-employment income or just $5 if you’re married to a foreigner) anywhere in the world are required to file a US federal tax return and pay taxes to the IRS, regardless of where in the world they live or where their income originates.

The good news is that there are various exclusions and credits available to reduce your US tax bill.

US taxes – what you need to know

If you earned more than US$12,550 (in 2021, or $400 of self-employment income etc), you are required to file Form 1040. While taxes are still due by April 15, expats get an automatic filing extension until June 15, which can be extended further online until October 15.

If you had a total of at least US$10,000 in one or more foreign bank and/or investment accounts at any time during the tax year, you also have to file FinCEN form 114, otherwise known as a Foreign Bank Account Report or FBAR.

If you have overseas assets worth over US$200,000 per person, excluding your home if it is owned in your own name, you also have to file form 8938 to declare them.

If you pay income tax in Portugal, there are several exemptions that allow you to pay less (or no) US income tax on the same income to the IRS. The main one is the Foreign Tax Credit, claimed on Form 1116, which gives you a $1 tax credit for every dollar of tax you’ve paid in Portugal. Alternatively, the Foreign Earned Income Exclusion, claimed on Form 2555, lets you exclude the first US$108,700 of foreign earned income from US tax if you can prove that you are a Portuguese resident. These exemptions can be combined if necessary, although not applied to the same income.

There is a US-Portugal Tax Treaty, however it doesn’t prevent expats from having to file US taxes. Some expats may be able to claim a provision in it though on specific types of income, such as dividends and royalties. If also contains a clause allowing the US and Portuguese governments to share taxpayer information, and Portuguese banks pass on US account holders’ account info to the IRS too, so it’s not worth not filing or omitting anything on your return or FBAR. The penalties for incorrect or incomplete filing for expats are steep, to say the least.

If you’re a US citizen, green card holder, or US/Portuguese dual citizen, and you have been living in Portugal but you didn’t know you had to file a US tax return, don’t worry: there’s a program called the IRS Streamlined Procedure that allows you to catch up on your filing without paying any penalties. Don’t delay though, as the program is only available before the IRS contacts you.
