Streamlined Filing Compliance Procedures: The Complete Checklist

Streamlined filing compliance procedures: an introduction

The streamlined filing compliance procedures are the IRS route for US taxpayers who missed returns, income or FBARs through non-wilful conduct. You file three years of tax returns and six years of FBARs, sign a certification, and pay the tax and interest due. Americans living abroad usually pay no penalty, while those living in the United States pay a 5% penalty.

This article is the practical checklist: what to gather, what to send, in what order, and where submissions go wrong. Our full guide to IRS Streamlined Filing from the UK explains the background and the wider choices.

Why a checklist for the streamlined filing compliance procedures helps

The IRS gives precise instructions, and it says returns that do not follow them are processed in the normal course without the favourable terms. Therefore, small slips matter. A missing label or an unsigned form can cost you the penalty relief you were filing for. Working through the steps in order avoids that.

Two versions of the same programme

There are two versions. The Streamlined Foreign Offshore Procedures are for taxpayers who meet a non-residency test. The Streamlined Domestic Offshore Procedures are for those who do not. Our article on Streamlined Foreign vs Domestic Offshore covers that choice in depth, so this checklist only flags where the steps differ.

Are you eligible for the streamlined filing compliance procedures?

You are eligible if your failures were non-wilful, the IRS has not opened an examination of your returns, and you have a valid taxpayer identification number. You must also meet the residency rules for the version you use.

Non-wilful conduct

Non-wilful conduct is conduct due to negligence, inadvertence or mistake, or a good-faith misunderstanding of the law. The IRS streamlined filing compliance procedures page uses that definition. You certify it under penalties of perjury. Consequently, if you knew about the rules and chose to ignore them, this is the wrong route. The IRS points such taxpayers to its Criminal Investigation Voluntary Disclosure Practice instead.

No examination or investigation under way

You cannot use the procedures if the IRS has opened a civil examination of your returns for any year. The same applies if you are under criminal investigation. However, people who made an earlier quiet disclosure can still apply. Any penalties already assessed for those years are not cancelled.

A valid taxpayer identification number

Every return must carry a valid taxpayer identification number. A US citizen or green card holder needs a Social Security number. If you are not eligible for one and have no ITIN, you send a complete ITIN application with the returns. An ITIN is a nine-digit IRS number for people who need a US tax number but cannot get a Social Security number, applied for on Form W-7. The IRS FAQs warn that someone eligible for a Social Security number who files without one loses the favourable penalty terms.

The residency test for each version

For the foreign version, a citizen or green card holder must have been outside the United States for at least 330 full days in one or more of the last three years. They must also have had no US abode in that year. Others must have failed the substantial presence test in one or more of those years. Anyone who fails the test uses the domestic version, which also requires that you already filed returns for those three years.

Which years do the streamlined filing compliance procedures cover?

You cover the three most recent tax years whose return due date has passed, and the six most recent years whose FBAR due date has passed. The window therefore moves forward each year.

Three years of tax returns

The tax return years are the most recent three for which the due date, or a properly applied-for extended due date, has passed. As of late October 2026, that normally means 2023, 2024 and 2025. Under the foreign version you file late original returns or amended returns. By contrast, the domestic version accepts only amended returns on Form 1040-X.

Six years of FBARs

An FBAR is the yearly report of foreign financial accounts filed with FinCEN. The IRS FBAR page says it is due on 15 April, with an automatic extension to 15 October. So as of late October 2026, the six years are 2020 to 2025. You file an FBAR for any year in which your foreign accounts together exceeded $10,000.

Information returns for the same years

Each return must include the information returns it should have had. For Americans in Britain, the common ones are Form 8938 for foreign assets and Form 8621 for UK funds. Additionally, Form 3520 covers some trusts and gifts, and Form 5471 covers certain UK companies you own.

Which documents should you gather first?

Gather statements for every foreign account for six years, your UK tax records for three years, and the facts behind why you did not file. Everything else is built from these.

Account statements for six years

For each FBAR year you need the maximum value of every account. That includes current accounts, savings, ISAs, pensions with an account value and any account you could sign on. Many UK banks keep only a few years of statements online. Therefore, request older statements early, because they can take weeks to arrive. Our article on the FBAR exchange rate explains how to convert each balance.

UK income and tax records for three years

Your US returns need your worldwide income for each calendar year. The UK tax year runs from 6 April to 5 April, so you split UK figures across two US years. Payslips, your P60 and your Self Assessment returns supply most figures. You also need the UK tax paid, because it usually funds the foreign tax credit.

The facts for your certification

Write down when you moved, when you first learned of the rules, and what you did next. Note the source of the money in each foreign account. In addition, record any adviser you relied on, with their details. These facts become the narrative on your certification, so collect them before drafting.

What do you submit, and in what order?

You prepare the returns, file the FBARs online, sign the certification, mark every return, pay, and then post the paper package to Austin. The order below keeps the figures consistent.

Step one: prepare the returns and information returns

Start with the returns, because they fix the income and asset figures everything else must match. Include every required information return for each year. Each return also claims your foreign tax credit or other relief for UK tax. The IRS FAQs for the foreign version cover special cases such as joint returns where one spouse will not sign.

Step two: file six FBARs electronically

The FBARs are filed separately, through FinCEN's BSA E-Filing System, not with the paper package. On the cover page, you select "Other" as the reason for filing late. Then you enter "Streamlined Filing Compliance Procedures" in the explanation box. Keep the confirmation for each one.

Step three: sign the certification

Foreign filers sign Form 14653, and domestic filers sign Form 14654. You send the signed original and attach a copy to each return and information return. However, you do not attach it to the FBARs. Form 14654 also shows your working for the 5% penalty.

Step four: mark every return

Write "Streamlined Foreign Offshore" or "Streamlined Domestic Offshore" in red at the top of the first page of each return. The label also goes on each information return. The domestic instructions call this critical to routing your returns through the special procedures. Consequently, it is the single easiest step to get right and the costliest to forget.

Step five: pay the tax, interest and any penalty

You pay all the tax shown on the returns plus statutory interest. If you pay by cheque, the IRS asks for your taxpayer identification number on it. Domestic filers also pay the miscellaneous offshore penalty. It equals 5% of the highest year-end total of the foreign assets that should have been reported, or whose income was left out. Foreign filers pay no such penalty. Our article on the Streamlined Domestic Offshore Procedures walks through that calculation.

Step six: post the package to Austin

The returns cannot be filed electronically under these procedures. Both versions go to Internal Revenue Service, 3651 South I-H 35, Stop 6063 AUSC, Austin, TX 78741. The attention line reads "Attn: Streamlined Foreign Offshore" or "Attn: Streamlined Domestic Offshore". Use a tracked service. That address is only for these submissions, so later returns go through normal channels.

Which mistakes cost you the favourable terms?

The common mistakes are a missing red label, a generic certification, missing information returns and the wrong years. Each can push returns into normal processing or invite questions.

A thin or generic certification

The IRS FAQs ask for specific reasons, the whole story, and both favourable and unfavourable facts. They also ask you to explain the source of funds in each foreign account. A one-line statement that you "did not know" rarely meets that standard. Furthermore, if spouses had different reasons, each should explain their own.

Missing forms or the wrong years

Leaving out Form 8621 for UK funds is common, because many people do not realise UK funds are caught. Equally, counting the years from the wrong due date can leave a gap. Our article on PFIC rules for UK funds explains which investments need the form.

Mixing up the two versions

Sending amended returns with the foreign label when you fail the 330-day test is a serious error. Likewise, a domestic filer cannot send late original returns. Therefore, settle your version first, using the day counts for all three years. Our article on the Streamlined Foreign Offshore Procedures covers the test in full.

How to correct a mistake

If the returns are not under examination, the FAQs let you send amended returns or an amended certification. You mark them "amended" in red and post them to the same Austin address. FBAR errors are corrected by filing amended FBARs online with FinCEN.

What does a full submission look like?

A worked example shows the checklist from start to finish. It is an illustration, not a real client.

An example: a teacher in Bristol

Consider a typical case. Rachel is a US citizen who moved to Bristol in 2016 and has never filed a US return. She has a current account, a savings account, a stocks and shares ISA and a workplace pension. She learned of the rules from a letter from her bank.

Rachel has spent every year in Britain, so she meets the 330-day test. First, she files late returns for 2023, 2024 and 2025, claiming credit for her UK tax. Next, she files FBARs for 2020 to 2025 online, with the streamlined explanation. Finally, she signs Form 14653, marks each return and posts everything to Austin.

What the example shows

Rachel's UK tax covered most of her US liability, so she owed little. Because she used the foreign version, she paid no 5% penalty. Her ISA, however, held UK funds, so her returns needed Form 8621. That single form is where many submissions fall short.

What happens after you submit?

Usually nothing visible happens: the IRS processes the returns like any others and does not confirm receipt. You then file normally every year from then on.

No acknowledgement and no closing agreement

The IRS does not acknowledge streamlined submissions, and the process does not end with a closing agreement. Returns can still be selected for audit like any other. Nevertheless, the relief for accuracy-related, information return and FBAR penalties generally still applies unless an examination finds fraud or wilful conduct.

Late FBARs on their own are not a safe route

The IRS removed its Delinquent FBAR Submission Procedures page in July 2026. Therefore, filing late FBARs on their own should not be treated as penalty-free. The IRS still describes separate delinquent international information return procedures, which have their own conditions. For most people with unreported income as well, the streamlined filing compliance procedures remain the main route.

Staying compliant afterwards

The IRS expects you to comply in every later year. Your next return and FBAR are filed in the normal way, not to the Austin address. In our experience, setting a yearly routine for statements and day counts keeps this simple.

How US UK Tax Experts can help

We prepare streamlined submissions for Americans in the UK and work through this checklist with you. First, we confirm your version from your day counts and gather the records. Next, we prepare the returns, information returns, FBARs and certification from one file. Finally, we assemble the marked package for you to sign and post. Our streamlined filing service sets out what is included.

Because we prepare your UK returns too, the figures on both sides agree. Our guide to FBAR and FATCA reporting covers the yearly filings that follow the streamlined filing compliance procedures.

Conclusion

In summary, the streamlined filing compliance procedures ask for three years of returns, six years of FBARs, a signed certification and full payment. Confirm you are eligible and which version applies before anything else. Then gather six years of statements and the facts behind your narrative. Above all, mark every return, file the FBARs online and post the package to the right address.
