Streamlined Non-Residency Requirement: The 330-Day Test Explained

To use the penalty-free foreign streamlined route you need at least 330 full days outside the United States in one of the last three tax years.

The streamlined non-residency requirement decides whether you pay no penalty or a 5% penalty under the IRS Streamlined Filing Compliance Procedures. A US citizen or green card holder meets it if, in at least one of the most recent three years for which the return due date has passed, they had no US abode and were physically outside the United States for at least 330 full days. On a joint return, both spouses must pass.

The Streamlined Foreign Offshore Procedures let Americans abroad catch up on missed returns and FBARs with no penalty. The Streamlined Domestic Offshore Procedures do the same job with a 5% charge. The only thing that separates them is where you lived. Therefore, the streamlined non-residency requirement is the first test to check, before any return is prepared. This guide explains the test, how days are counted, and the cases that fail unexpectedly.

What the streamlined non-residency requirement says

The IRS sets out the rule on its page for U.S. taxpayers residing outside the United States. There are two versions, depending on your status.

US citizens and green card holders

You must look at the most recent three tax years for which the US return due date, or properly extended due date, has passed. In any one or more of those years, you must have had no US abode and have been physically outside the United States for at least 330 full days. One qualifying year is enough. The other two years can fail.

People who are neither citizens nor green card holders

A different test applies to someone who became a US tax resident only by presence. You meet the requirement if, in any one or more of the same three years, you did not meet the substantial presence test in section 7701(b)(3) of the Internal Revenue Code.

Joint filers

The IRS states that for joint return filers, both spouses must meet the applicable requirement. Consequently, one spouse who spent long periods in the US can prevent the couple from using the foreign procedures on a joint submission.

How the 330 full days are counted

The test looks simple, but the detail matters. A year has 365 days, so 330 days abroad leaves a maximum of 35 days in the United States, or 36 in a leap year.

Full days only

A full day is a 24-hour period spent outside the United States. The day you land in the US and the day you leave are not full days abroad. Therefore, a ten-night trip to see family costs eleven days, not ten. You should count from passport stamps, airline records and calendar entries, and keep that evidence.

It is a calendar-year test

The streamlined test measures each tax year separately. It is not the same as the physical presence test for the Foreign Earned Income Exclusion, which uses any period of 12 consecutive months and counts days in foreign countries. As a result, you can qualify for the exclusion and still fail the streamlined test for the same year, or the reverse.

The US abode condition

The IRS applies the meaning of abode used in section 911 of the Internal Revenue Code. Your abode is where your home, family and economic life are centred. Owning a US property that is let out does not usually create a US abode. However, keeping a US home ready for your use, with your family living there, can.

Foreign or domestic: what the result means

Passing or failing does not decide whether you can use the Streamlined Filing Compliance Procedures at all. It decides which version applies. The IRS describes both on its Streamlined Filing Compliance Procedures page.

Who fails the streamlined non-residency requirement

Most long-term residents of the UK or UAE pass without difficulty. The failures come from a few recurring patterns.

Recent movers

If you moved abroad part-way through a year, that year will not contain 330 full days outside the US. You need a later, complete year, and its return due date must have passed. For example, someone who moved to London in March 2025 first has a qualifying year in 2026, and that year only counts once the 2026 return deadline has gone by in 2027.

Long visits home

A single extended stay can break a year. Caring for a parent, a family emergency or a long US work assignment can each take you past 35 days. The procedures contain no exception for the reason. However, because only one year in three must qualify, an isolated long visit is rarely fatal.

Rotational and commuting workers

People who split their time, such as offshore workers on rotation or executives who commute to a US office, often exceed 35 US days every year. They generally fall under the domestic procedures, even if they consider themselves resident abroad.

How you certify the requirement

You certify non-residency on Form 14653. The form asks you to state, for each of the three years, whether you were outside the United States for at least 330 full days, and to explain your failure to file in a narrative. You sign under penalty of perjury. Our guide to Form 14653 and the non-wilful certification explains how to write the statement, and our guide to which years a streamlined filing covers explains the three-year window.

UK residence is a separate question

The test uses US concepts only. Whether HMRC treats you as UK resident under the Statutory Residence Test does not decide it. GOV.UK explains the UK rules in its guidance on UK residence and tax. In practice, a person who is UK resident all year normally passes, but the streamlined test still has to be met on its own terms. Our US expat tax returns page covers the returns that go into the submission.

An illustrative case

Consider an illustrative US citizen who has lived in Glasgow since 2015 and has never filed a US return. The figures are illustrative. She prepares a submission in late 2026, so the relevant years are 2023, 2024 and 2025. In 2023 she spent 48 days in Ohio helping her mother move. In 2024 she spent 21 days in the US, and in 2025 she spent 14. Her home, job and family are in Glasgow. She fails for 2023 but passes for 2024 and 2025. One year is enough, so she meets the streamlined non-residency requirement and files under the foreign procedures with no penalty.

If you are unsure which procedure applies, book a consultation with our team. We count the days, test the streamlined non-residency requirement for each year and prepare the full submission.

Frequently Asked Questions

What is the streamlined non-residency requirement?

It is the test that decides whether a taxpayer uses the Streamlined Foreign Offshore Procedures. A US citizen or green card holder meets it if, in at least one of the most recent three years for which the return due date has passed, they had no US abode and were physically outside the United States for at least 330 full days.

How many days can I spend in the US and still qualify?

You can spend up to 35 days in the United States in a 365-day year, or 36 in a leap year, because you need 330 full days outside. Days of arrival and departure are not full days abroad, so they count against you.

Do I need to meet the 330-day test in all three years?

No. The IRS requires the test to be met in any one or more of the most recent three years for which the US tax return due date, or properly extended due date, has passed. One qualifying year is sufficient.

What happens if I fail the non-residency requirement?

You can still use the Streamlined Domestic Offshore Procedures if your conduct was non-wilful. That route carries a miscellaneous offshore penalty of 5% of the highest aggregate year-end balance of the relevant foreign financial assets, and you certify on Form 14654 instead of Form 14653.

Does being UK tax resident mean I automatically pass?

No. HMRC's Statutory Residence Test is a UK rule and is not part of the IRS test. The streamlined requirement looks only at whether you had a US abode and how many full days you spent outside the United States in each year.

I work in the UAE on rotation and spend six weeks a year in the US. Do I qualify?

Probably not for those years. Six weeks is 42 days, which leaves fewer than 330 full days outside the United States. Unless one of the three relevant years had 35 or fewer US days and no US abode, the Streamlined Domestic Offshore Procedures apply instead.
