Behind on US taxes and contacted by the IRS: what to do
What to do if behind on taxes
If the IRS already contacted you, do not ignore the notice. Check the deadline, the tax year, and what the IRS is asking for. If you are behind on taxes, the safest first move is usually to file the missing returns even if you cannot pay in full right away.
Some expats may qualify for the Streamlined Filing Compliance Procedures, but that is not the answer for every case.
The IRS may offer payment plans, and penalty relief may be available in the right facts, but interest relief is much narrower.
Getting an IRS letter after falling behind can feel worse than the problem itself. The good news is that most cases can still be brought under control with a clear sequence: understand the notice, stop the delay, gather the right records, file the missing returns, and then address payment or relief options.
This guide keeps the original TFX tone and explains the process in plain English for expats and other US taxpayers. It also reflects current IRS guidance on notices, late returns, payment plans, penalty relief, transcripts, and the Streamlined procedures.
What to do first if the IRS already contacted you
Start with the letter itself. The IRS notice will usually tell you the tax year involved, what the IRS believes is missing, whether a response is required, and when that response is due. If the notice asks for a reply, the IRS says you should respond by the due date on the letter.
Use the IRS notice guidance page to understand the notice number and next steps before you react.
- Confirm the notice number and the response deadline.
- Check whether the IRS wants a missing return, supporting documents, payment, or just confirmation.
- Match the notice to the right tax year before you send anything.
- Do not assume the IRS is always correct. Sometimes the agency is working from incomplete records.
If you are behind in filing taxes, you usually still have a path to get caught up
Falling behind does not automatically mean the situation is beyond repair. In many cases, the fix begins with filing the missing returns and correcting any missing foreign reporting. The IRS specifically tells taxpayers to file all past-due returns that are due, even if they cannot pay immediately.
For expats, that may mean standard late filing, or it may mean evaluating the Streamlined Filing Compliance Procedures if the failure was non-willful and the eligibility rules are met.
That distinction matters. A normal late-filing case and a Streamlined case are not the same thing. Some Americans abroad qualify for Streamlined treatment, but not every taxpayer who is behind in filing taxes should assume that program applies.
Behind on taxes - what to do: choose the right path instead of the fastest path
One of the biggest mistakes in this area is treating every late-filing situation as if there is one universal fix. There is not. The right approach depends on whether you live abroad, whether you were non-willful, whether FBARs are missing, and whether the IRS has already started an examination.
| Situation | Best next step | What usually gets filed |
|---|---|---|
| You missed returns but there is no special offshore issue | File all overdue returns that are due and address payment separately | The missing federal returns for each year involved |
| You lived abroad, were non-willful, and foreign reporting was missed | Review Streamlined Foreign Offshore eligibility carefully | Most recent 3 years of tax returns and 6 years of FBARs |
| You live in the US and may qualify for Streamlined | Review Streamlined Domestic Offshore rules and the 5% penalty framework | Most recent 3 years of tax returns and 6 years of FBARs |
| The IRS has already opened a civil examination | Get case-specific professional advice before assuming Streamlined is available | Case-specific response, not a standard one-size-fits-all filing |
The IRS says the Streamlined procedures generally involve the most recent 3 years of delinquent or amended returns plus 6 years of delinquent FBARs. Just as important, the IRS also says those procedures are not available if it has already started a civil examination, no matter whether the examination relates to the delinquent returns.
See the IRS pages for taxpayers residing outside the US and taxpayers residing in the US for the detailed rules.
Respond to the IRS early, even if you still need time
Silence makes a bad tax issue harder to fix. If you received a notice and need more time to collect records or prepare missing filings, the better move is to communicate rather than disappear. In practice, this helps preserve options and lowers the chance that the case escalates unnecessarily.
This section should stay human. Many expats delay because they feel embarrassed, overwhelmed, or stuck abroad without easy access to documents. That is common. But from a practical standpoint, the IRS will care more about whether you acted than whether you felt ready.
Behind on my taxes: gather records in the right order
Document gathering is where late-filing cases either speed up or stall. Start with the records that define the return, not the records that are merely nice to have. For many taxpayers, that means wage and income information, account transcripts, prior-year returns, and foreign account data.
The IRS now pushes taxpayers first toward Online Account for Individuals and Get Transcript. Form 4506-T is still a fallback, but it should not be your only plan.
- Get wage and income records for the years involved.
- Pull account transcripts to see balances, penalties, and some filing history.
- Collect prior returns, if any, because carryovers may affect later years.
- For expats, gather foreign bank statements and prior FBAR-related information.
- If foreign tax credits may apply, collect local tax returns and payment evidence.
If you are years behind on taxes, filing the oldest year first can be important because items such as capital loss carryovers and some credits flow forward into later years.

What to do if behind on taxes and the IRS has made assumptions for you
Sometimes the IRS builds a case from incomplete information. It may think a return is missing, or it may have created a substitute return based only on income documents it received from third parties. When that happens, deductions, exclusions, credits, and foreign reporting context may be missing from the IRS view.
That is one reason late filers should not panic when the notice amount looks too high. The number may reflect a rough IRS estimate rather than the final liability once a real return is filed.
The IRS explains this general process in its pages on filing past-due returns and notices for past-due tax returns.
Behind on filing tax returns: file even if you cannot pay yet
For most taxpayers, filing and paying are two separate problems. The IRS generally wants the return first. Waiting to file because you cannot pay usually makes the situation more expensive, not less.
The current IRS late-filing rules are blunt: the failure-to-file penalty is generally 5% of unpaid tax for each month or part of a month the return is late, up to 25%. The failure-to-pay penalty is generally 0.5% per month, also up to 25%. For returns required to be filed in 2026, the minimum late-filing penalty for a return over 60 days late is generally the lesser of $525 or 100% of the tax required to be shown on the return.
That is why filing first usually saves money, even before you solve the payment side. If you are behind on filing tax returns, the return itself is often the first lever you can still pull today.
| If you owe | What it means | Best use case |
|---|---|---|
| Pay in full | Stops balance growth fastest | You can clear the issue without ongoing collection risk |
| Installment plan | You pay over time under IRS-approved terms | You can file now but need time to pay |
| Offer in Compromise | Possible settlement for less than full amount | You cannot pay in full and the facts support it |
The IRS says an Offer in Compromise may be an option if you cannot pay your full tax liability or doing so would create financial hardship. The IRS says it considers your ability to pay, income, expenses, and asset equity. Many taxpayers who do not qualify for an offer still qualify for payment plans or installment agreements.
Behind on taxes and need help: know when DIY stops making sense
Some late-filing cases are manageable without a professional. Others are not. Once you add foreign accounts, FBAR exposure, missed Forms 8938 or 8621, substitute returns, multiple countries, or a live IRS notice, the risk of choosing the wrong path gets much higher.
The IRS has its own pages on choosing a tax professional and understanding tax preparer credentials. For expat cases, specialized international tax experience matters more than generic return-prep volume.
- DIY is more realistic if your case is limited to one or two missing simple returns with no foreign reporting problems.
- Professional help becomes much more valuable if you are handling foreign accounts, FBARs, multiple missed years, or an active IRS notice.
- For complex cases, the real value is often not just preparing forms. It is choosing the right compliance path before you file anything.
Can the IRS waive penalties or interest?
Relief is possible, but this is where many articles overpromise. Penalty relief and interest relief are not the same thing.
The IRS says reasonable-cause relief may be available in some cases. It also provides administrative penalty relief in certain situations, including first-time abate in some cases. Interest abatement is much narrower and generally depends on unreasonable IRS error or delay rather than on the taxpayer simply having a good explanation.
See reasonable cause penalty relief, administrative penalty relief, interest abatement, and Form 843 for the current IRS framework.
- Penalty relief can be realistic if you have a credible, documented reason and the facts fit IRS rules.
- Interest relief is harder. A sincere explanation alone usually is not enough.
- Do not ask for relief before the filing record is clear. In most cases, you first need the missing returns processed.
A practical checklist for expats who are behind on taxes
- Read the notice carefully and mark the response date.
- Identify every missing year, not just the one named in the notice.
- Pull transcripts and supporting records.
- Decide whether this is standard late filing or a possible Streamlined case.
- File the missing returns even if full payment is not possible.
- Review payment-plan or Offer in Compromise options only after the filing path is clear.
- Consider penalty relief after the returns are processed and the facts are documented.

FAQs on what to do after IRS contact if you are behind on taxes
Usually start by understanding the letter and the deadline, then move quickly toward filing the missing returns. If the case is simple, the filing itself often solves the main issue. If the notice is complex, or foreign reporting is involved, get advice before choosing a path.
Focus on triage, not perfection. Confirm the years involved, gather transcripts and income records, and stop the delay. If you are overwhelmed, the best help is often someone who can tell you whether the case is standard late filing, Streamlined, or something that needs direct IRS-notice handling.
No. The six-year idea is often misunderstood. Under the Streamlined procedures, the IRS generally asks for the most recent 3 years of returns and 6 years of FBARs. Outside that program, the IRS says taxpayers should file all past-due returns that are due.
File anyway. Late filing can trigger steeper penalties than late payment. Once the returns are filed, you can review payment plans or, in harder cases, whether an Offer in Compromise is realistic.
Start with transcripts, wage and income records, prior returns, and foreign account information. IRS Online Account and Get Transcript are usually the fastest starting points. Form 4506-T can still help in some situations.
That misunderstanding is common among Americans abroad. The US taxes citizens and many other US taxpayers on worldwide income. In some cases, exclusions or credits may reduce the tax, but they do not erase the filing requirement.
