Form 8840 closer connection statements let a non-US citizen who meets the IRS substantial presence test still be treated as a nonresident. You qualify only if you spent fewer than 183 days in the US during the year, kept a tax home abroad all year, had a closer connection to that country and never applied for a green card. You must file Form 8840 on time.

British and Emirati professionals who split time between London or Dubai and New York, Florida or Texas often trip the substantial presence test without realising it. Once that happens, the IRS treats you as a US tax resident and taxes your worldwide income. Form 8840 is the cheapest and simplest way back out, but only if you meet every condition and file by the deadline. This guide explains who qualifies, how to complete the form and what happens if you miss it.

What the Form 8840 closer connection exception does

Form 8840, Closer Connection Exception Statement for Aliens, is a statement you file with the IRS. It tells the IRS that although your day count makes you a resident under section 7701(b) of the Internal Revenue Code, your real life sits in another country. If the IRS accepts it, you remain a nonresident alien and pay US tax only on US-source income.

The substantial presence test it overrides

You meet the substantial presence test for 2025 if you were in the US for at least 31 days in 2025 and 183 days across 2023 to 2025. The 183-day total counts every day in 2025, one third of the days in 2024 and one sixth of the days in 2023, according to the IRS Form 8840 (2025). Consequently, someone who spends 120 days in the US every year reaches only 180 weighted days (120 + 40 + 20), while 122 days a year reaches 183 and triggers US residency. Our guide to the substantial presence test for UK citizens walks through the day-counting rules in detail.

Why the exception matters for UK and UAE residents

US residency brings a full Form 1040, worldwide income, FBAR reporting and possibly Form 8938. For a UK resident, that means reporting a UK salary, ISA income and pension growth to the IRS. For a Dubai resident, it means paying US tax on income the UAE does not tax at all. Therefore, the exception can save a five-figure compliance burden every year.

Who qualifies for the closer connection exception

The IRS sets four conditions on its closer connection exception page. You must meet all of them for the same calendar year.

Condition (IRS, 2025 Form 8840)What it means in practice
Fewer than 183 days in the US in the current yearCount the current year only, not the weighted three-year total
Tax home in a foreign country for the whole yearYour main place of business or work is in the UK, UAE or another country
Closer connection to that country than to the USHome, family, belongings, bank accounts and licences sit abroad
No green card application or pending status changeFiling Form I-485, I-130 or I-140, for example, disqualifies you

The tax home test

Your tax home is generally your regular or main place of business, wherever your family home happens to be. For instance, a London-based consultant who flies to Boston for project work keeps a UK tax home. In contrast, a person with no regular place of work has a tax home where they regularly live. Specifically, the tax home must exist for the entire year, so a mid-year move to the US usually breaks the exception.

Proving the closer connection

The IRS weighs where you keep your permanent home, family, personal belongings, cars, bank accounts and social ties. It also looks at your driving licence, voter registration, charitable giving and the country you name on forms such as Form W-8BEN. Moreover, Part IV of Form 8840 asks these questions directly, so your answers become evidence. Keep a UK council tax bill, a UAE tenancy contract registered with Ejari, or school enrolment records in case the IRS asks.

Who cannot claim it

Green card holders cannot use Form 8840. Neither can anyone who applied, or took steps to apply, for lawful permanent residence during the year. Additionally, a person with 183 days or more in the current year is excluded, however strong their foreign ties. Those taxpayers need a different route, usually the treaty tie-breaker covered below.

How to file Form 8840

Form 8840 is a four-part statement. Part I covers your identity and visa, Part II your days of presence, Part III your tax home and Part IV your closer connection facts. You sign it under penalties of perjury.

Form 8840 closer connection deadlines

If you file a Form 1040-NR, attach Form 8840 to it. If you have no US filing requirement, mail Form 8840 on its own to the Department of the Treasury, Internal Revenue Service Center, Austin, TX 73301-0215, by the Form 1040-NR due date including extensions. For 2025 that is generally 15 April 2026 if you received US wages subject to withholding, and 15 June 2026 if you did not, per the IRS Form 1040-NR instructions.

What happens if you file late

Late filing is costly. The Form 8840 instructions state that a person who does not file on time is not eligible for the exception and may be treated as a US resident. The only relief applies if you show, by clear and convincing evidence, that you took reasonable steps to learn the rules and made significant efforts to comply. As a result, a missed Form 8840 can turn a simple nonresident year into a full resident return.

Form 8840 versus the treaty tie-breaker

Form 8840 is not the only way to stay nonresident. Article 4 of the UK-US tax treaty contains tie-breaker rules for people resident in both countries. However, the two routes work very differently.

FeatureForm 8840 closer connectionTreaty tie-breaker (Form 8833)
Legal basisIRC section 7701(b)(3)(B)UK-US treaty Article 4
Day limit in current yearFewer than 183 daysNo fixed limit
UAE residentsAvailableNot available, as there is no US-UAE income tax treaty
Return neededStatement only, if no US incomeForm 1040-NR with Form 8833
Status for other US rulesNonresident for all purposesResident for some reporting rules, such as FBAR

Notably, UAE residents rely on Form 8840 alone, because the US and UAE have no comprehensive income tax treaty. Our article on the UK-US treaty tie-breaker rule explains when the treaty route works better for UK residents.

A worked example

Consider an illustrative client, a British software director living in Manchester. She spent 150 days in the US in 2025, 140 in 2024 and 130 in 2023. Her weighted total is 150 + 46.7 + 21.7 = 218.4 days, so she meets the substantial presence test. However, she spent fewer than 183 days in 2025, works for a UK company, owns her Manchester home and has never applied for a green card.

She therefore files Form 8840 by 15 June 2026, since she received no US wages. In our experience, clients in this position often assume they are safe because they "never stayed six months". The weighted count catches them, and the deadline then decides whether they stay nonresident. Furthermore, she keeps her flight records, because the IRS can ask for day counts years later.

Frequently Asked Questions

What is Form 8840 used for?

Form 8840, Closer Connection Exception Statement for Aliens, lets a non-US citizen who meets the IRS substantial presence test claim to be a nonresident alien. The person must have spent fewer than 183 days in the US that year, kept a foreign tax home all year and had a closer connection to that country.

When is Form 8840 due for the 2025 tax year?

Form 8840 for 2025 is due by the Form 1040-NR due date, including extensions. That is generally 15 April 2026 for people with US wages subject to withholding and 15 June 2026 for everyone else. People with no US return to file mail it alone to the IRS Service Center in Austin, Texas.

Can a UK citizen use the closer connection exception?

Yes, a UK citizen can use the closer connection exception if they spent fewer than 183 days in the US in the year, kept a UK tax home for the whole year and had closer ties to the UK. A UK citizen who applied for a US green card during the year cannot claim it.

Can a UAE resident file Form 8840?

Yes, a UAE resident who is not a US citizen or green card holder can file Form 8840 if they meet the IRS conditions. Form 8840 is especially important for UAE residents, because the US and UAE have no comprehensive income tax treaty, so the UK-US style treaty tie-breaker is not available to them.

What happens if I do not file Form 8840 on time?

If you do not file Form 8840 on time, the IRS treats you as ineligible for the closer connection exception and you may be taxed as a US resident on worldwide income. The IRS grants relief only if you show, by clear and convincing evidence, that you took reasonable steps to learn and meet the filing requirement.

Does filing Form 8840 affect my UK tax position?

No, Form 8840 is a US filing and has no direct effect on UK tax residence. HMRC decides UK residence under the Statutory Residence Test, which uses its own day counts and ties. A person can be UK resident under the Statutory Residence Test and nonresident for US purposes under Form 8840 in the same year.

Is Form 8840 the same as Form 8843?

No, Form 8840 and Form 8843 serve different purposes. Form 8840 claims the closer connection exception for people who meet the substantial presence test. Form 8843 is used by exempt individuals, such as certain students, teachers and people with a medical condition, to exclude days from the substantial presence count.
