Late Filings, Amendments
& IRS Notices

Support with prior-year returns, catch-up filings, amended returns, streamlined compliance questions, and practical responses to IRS or state notices.
Tax problems rarely begin with one dramatic mistake. More often, they build quietly: a missed filing year, an incorrect return that needs to be fixed, a foreign account that was never reported, or an IRS notice that arrives without clear context. What makes these cases stressful is not only the tax itself, but the uncertainty around what should be corrected, what can still be amended, and how quickly the issue needs to be addressed.
We help with prior-year tax returns, catch-up filings, amended returns, streamlined compliance questions, and practical responses to IRS or state notices.
For individual returns, corrections are generally made on Form 1040-X, and the IRS states that Form 1040-X can be e-filed for the current year and up to two prior tax periods in supported cases. The IRS also notes that refund claims are generally time-sensitive, with the usual rule being three years from the date the original return was filed or two years from the date the tax was paid, whichever is later.

Late filings should not be ignored just because the year has passed. The IRS specifically instructs taxpayers to file past-due returns and explains that failure-to-file penalties can grow quickly. In general, the failure-to-file penalty is 5% of the unpaid tax for each month or part of a month the return is late, up to 25%, and if a return is more than 60 days late, a minimum penalty may apply.

Not every notice means the same thing, and not every notice requires the same response. The IRS says notices may be issued because of a balance due, a changed refund, questions about a return, identity verification, or corrections the IRS made during processing. That is why the right first step is usually analysis, not panic.
Our role is to turn a messy filing history into a clear action plan: identify what is missing, determine what should be amended, evaluate deadlines and penalty exposure, and prepare a practical response that is technically sound.
We also assist with streamlined compliance questions where missed international filings may need to be corrected. The IRS maintains separate Streamlined Filing Compliance Procedures for eligible taxpayers, and those procedures can intersect with amended or delinquent returns in ways that need to be handled carefully.


Important disclosure: late filings, amendments, notice responses, and streamlined compliance issues are highly fact-specific. The correct approach depends on the tax year involved, whether tax is due or a refund is claimed, the nature of the error, prior filing history, and whether domestic or international reporting obligations are affected.

FAQ
In many cases, yes. The IRS states that U.S. citizens and resident aliens living abroad are generally subject to U.S. tax on worldwide income and may still need to file U.S. returns even when they live and work outside the United States. Many expats may also qualify for relief such as the Foreign Earned Income Exclusion (FEIE) or the Foreign Tax Credit (FTC), but those benefits generally must be claimed on a filed return.
