Unfiled returns

Washington, DC unfiled tax return matters.

Mr. Powell handles unfiled return matters nationwide, from the first IRS missing-return letter through any substitute return the IRS has already prepared. Review each unfiled year separately for assessment and refund limits. If no return is filed, section 6501(c)(3) permits the IRS to assess tax at any time. An IRS substitute return under Internal Revenue Code section 6020(b) does not start that assessment limitations period. Section 6511 separately governs refund claims; section 6511(b)(2) limits the amount recoverable by reference to when the tax was paid, subject to exceptions. Filing an old return does not by itself establish a right to a refund. This page does not calculate a deadline.

The firm has an office at 1629 K Street NW, Suite 300 in Washington, DC and represents individuals and closely held businesses in matters involving unfiled returns.

Each matter begins with the unfiled years, any IRS missing-return letter, and whether the IRS has already prepared a substitute return.

The filing procedures on this page were checked on the cited official sources on September 7, 2026. The questions and answers below were rewritten on September 10, 2026 from those same sources. Read the notice together with the governing law and any applicable deadline relief. This page does not calculate an individual deadline.

What happens if I have not filed for several years?

A year with no return filed does not close on its own. Internal Revenue Code section 6501(c)(3) permits the IRS to assess tax at any time for that year, and section 6020(b) lets the IRS prepare a substitute return without you. The IRS tells taxpayers to file all required returns that are due, whether or not the tax can be paid in full. Filing can limit additional failure-to-file penalty, preserve a refund claim within the time the law allows, and put the account on a collection path that requires current filings.

Prepare your own return even if the IRS has prepared a substitute return. IRS guidance explains that the substitute may omit tax benefits you are entitled to claim and that the IRS will generally adjust the account to reflect the correct figures when you file. Check the income shown against your records. If a payer reported incorrect income, the IRS instructs taxpayers to contact that payer for a corrected wage or income statement and attach it to the completed return. If a Notice of Deficiency has arrived, review that notice before choosing a response.

Extension, amendment, and a year that was never filed.

The IRS tells taxpayers who have not filed to file the returns that are due. That instruction is not the same as an extension and not the same as an amendment.

Form 4868 is an application for an automatic extension of time to file a U.S. individual income tax return. It extends time to file. It does not extend time to pay.

Form 1040-X is an amended U.S. individual income tax return. The IRS says to use it to correct a Form 1040, 1040-SR, or 1040-NR already filed, to make certain elections after the deadline, to change amounts the IRS previously adjusted, or to claim a carryback.

Check whether you already filed the return before responding to a missing-return notice. If you have not filed, IRS guidance directs you to send the past-due return to the location stated in the notice. Without a notice, the IRS says to use the same filing method and location as for an on-time return. If you already filed the past-due return and received a notice, the IRS says to send a copy to the address indicated. Read the notice before sending anything.

The work

Inventory the years.

  1. Inventory the years

    Identify each unfiled year, the type of return, and any IRS letter already received, including a missing-return notice such as CP59.

  2. Gather the records

    Collect wage statements, information returns, bank records, and prior filings that show income, deductions, and filing status for each year.

  3. File the returns that are due

    The IRS position is to file required returns whether or not the tax can be paid in full. Payment options are a separate question after the return is filed.

  4. Address what the IRS has already done

    If the IRS prepared a substitute for return or issued a Notice of Deficiency, the next step follows that document, not a general filing checklist.

When foreign reporting is also missing.

The IRS Voluntary Disclosure Practice and the Streamlined Filing Compliance Procedures address different circumstances. Streamlined procedures require a certification of non-willful conduct and have additional eligibility requirements, including restrictions for taxpayers under examination or criminal investigation. The Voluntary Disclosure Practice addresses willful noncompliance and requires a timely disclosure; it does not guarantee immunity from prosecution. Assess eligibility and the filing approach before submitting returns or a disclosure. Read FBAR and foreign-account reporting when foreign accounts are part of the years at issue.

Questions

Common questions.

  • What should a taxpayer do about unfiled tax returns?

    The IRS tells taxpayers to file all required returns that are due, whether or not the tax can be paid in full. Filing can limit additional failure-to-file penalty, preserve a refund claim within the time section 6511 allows, and put the account on a collection path that requires current filings. A year with no return filed does not close on its own, because Internal Revenue Code section 6501(c)(3) permits the IRS to assess tax at any time for that year. The firm represents individuals and closely held businesses in matters involving unfiled returns.

  • What is an IRS substitute for return?

    Where no return is filed, Internal Revenue Code section 6020(b) lets the IRS prepare a substitute return without the taxpayer. That substitute may omit deductions and credits the taxpayer could have claimed on an original filing, and it does not start the assessment limitations period, so section 6501(c)(3) continues to permit assessment at any time. A substitute for return can be followed by a Notice of Deficiency, which opens the Tax Court petition period under section 6213(a). Filing an original return for the year is still the step the IRS asks for.

  • Can the IRS consider a payment plan if returns are unfiled?

    Most payment plans and relief options require that the required tax returns are filed, so the filing comes before the payment question. Once the returns are in, an individual owing $50,000 or less in combined tax, penalties, and interest can request a payment plan online, and larger balances or a partial-payment agreement run through a financial disclosure instead. If the IRS has already billed the years, the collection notice in hand sets the next step and the date.

  • How are unfiled income tax returns different from a missing FBAR?

    Past-due income tax returns are a filing problem on the federal income tax return, worked through Internal Revenue Code sections 6501 and 6511. The FBAR is a separate Treasury report on FinCEN Form 114, required under 31 U.S.C. section 5314 when foreign financial accounts exceeded $10,000 in the aggregate at any time during the calendar year, and it is filed with FinCEN rather than with the return. A person can have one problem, the other, or both.

  • What IRS letter means the IRS has no record of a required return?

    CP59 tells the taxpayer the IRS has no record of a required return for a year. CP88 tells the taxpayer the IRS is holding a refund because of unfiled returns. Each prints the year at issue and the response instructions, and IRS guidance directs a past-due return to the location stated in the notice. Where the IRS has already prepared a substitute return under section 6020(b), the next paper is usually a Notice of Deficiency instead.

  • What is the difference between Form 4868, Form 1040-X, and an unfiled year?

    The IRS tells taxpayers who have not filed to file the returns that are due, and that instruction is neither an extension nor an amendment. Form 4868 extends time to file a U.S. individual income tax return. It does not extend time to pay. Form 1040-X amends a Form 1040, 1040-SR, or 1040-NR already filed. An extension request does not supply a missing return. For an unfiled year, the questions are which original return is required and whether the IRS has already prepared a substitute return or adjusted the account.

If the IRS has already assessed or billed the years.

A balance-due series such as CP14 is a collections problem. Read IRS collections. A Notice of Deficiency is a Tax Court problem. Read U.S. Tax Court. Use the IRS Letter Check for a supported notice code.

For a Maryland resident, a Chapter 13 plan can also pay priority tax debt over time under court supervision; see Chapter 13 for IRS back taxes.
