Executive Summary for the Taxpayer
A late 2025 return is still worth filing immediately, whether you expect a refund or owe the IRS. If earlier returns are missing, you can rebuild your filing history, replace any IRS-prepared returns, and evaluate First Time Abatement, reasonable-cause relief, and the IRS’s new Automatic Exemption from Penalty process.

Not filing does not make the tax issue disappear. It can delay refunds, increase penalties and interest, prevent accurate income reporting, and lead the IRS to prepare a return using incomplete information (IRC § 6651; IRS, Filing Past Due Tax Returns).

For New Jersey residents, federal and New Jersey filing obligations should be reviewed separately. A complete resolution plan may require federal Form 1040 returns, NJ-1040 returns, payment arrangements, and separate federal or state penalty requests (New Jersey Division of Taxation).

Part 1 : It’s Not Too Late : File Your 2025 Return ASAP

The 2025 federal individual income tax return was generally due April 15, 2026. If you requested a valid extension, the filing deadline is generally October 15, 2026, but an extension of time to file is not an extension of time to pay (IRS, When to File; IRS, Get an Extension to File).

If you did not file an extension, your return is already late. Filing late is still better than allowing another month of noncompliance to pass because the failure-to-file penalty generally accrues at 5% of unpaid tax per month or partial month, up to 25% (IRC § 6651(a)(1); IRS, Failure to File Penalty).

What to do now

  1. Gather your 2025 records. Collect Forms W-2, 1099-NEC, 1099-MISC, 1099-INT, 1099-DIV, mortgage interest statements, health insurance information, business records, and documentation for dependents and credits.
  2. Determine whether you have a balance due or expect a refund. The result affects the immediate financial consequences, but it does not change the need to file.
  3. File the correct 2025 return. Use the appropriate federal Form 1040 package and include all required schedules, including Schedule C for qualifying business activity.
  4. Pay what you can immediately if you owe. Payment reduces the amount subject to the failure-to-pay penalty and interest (IRC § 6651(a)(2); IRS, Topic No. 653).
  5. Request an IRS payment plan if necessary. An installment agreement does not erase the tax, but it can provide a structured way to address the balance (IRS, Online Payment Agreement).

If your properly prepared return shows that the IRS owes you a refund, the IRS generally does not impose a failure-to-file penalty because there is no unpaid tax on which to calculate that penalty (IRS, Filing Past Due Tax Returns). The greater risk is losing the refund or refundable credit by waiting beyond the applicable refund limitation period (IRC § 6511).

For a 2025 return filed without a prior extension, a refund claim is generally subject to the applicable three-year limitation measured from the return due date, subject to statutory exceptions. That makes filing now important even if you believe you owe nothing (IRS, Time You Can Claim a Credit or Refund).

Part 2 : Still Have Back Years? No Problem

Multiple unfiled years require organization, not avoidance. The IRS instructs taxpayers to file all returns that are due, even if they cannot pay the full amount immediately (IRS, Filing Past Due Tax Returns).

People often hear that they only need to file the “last six years.” Six years is a common administrative compliance period, but it is not a universal statute of limitations that automatically eliminates older filing obligations. The IRS may consider additional years depending on the taxpayer’s history, income, assets, business activity, and collection circumstances (IRS Policy Statement 5-133).

A practical reconstruction process

  1. List every year that may be missing. Review prior notices, mortgage applications, employer records, bank records, and any tax software accounts.
  2. Check your IRS account. Your Individual Online Account may show transcripts, payment history, and information-reporting documents (IRS, Get Your Tax Records and Transcripts).
  3. Order wage and income transcripts. Wage and income transcripts can help identify W-2s, 1099s, and other information reported to the IRS; Form 4506-T is one method for requesting transcript information (IRS, Form 4506-T).
  4. Contact employers, financial institutions, and payers. IRS transcripts may not contain every document needed to substantiate deductions or business expenses.
  5. Prepare each year using the law applicable to that tax year. Tax brackets, credits, deductions, filing thresholds, and forms can change from year to year.
  6. File the returns in an orderly sequence. Filing the oldest required year first can help clarify carryforwards, filing status, business losses, and later-year information.

The IRS may prepare a Substitute for Return, commonly called an SFR, when a taxpayer does not file. An SFR generally uses third-party income information but may not include deductions, exemptions, dependents, or credits that the taxpayer could have claimed on a properly prepared return (IRC § 6020(b); IRS, Filing Past Due Tax Returns).

The IRS may issue a Statutory Notice of Deficiency, such as CP3219N, before making the proposed assessment final. A taxpayer generally has 90 days from the date of the notice to petition the United States Tax Court, so a statutory notice should be reviewed immediately (IRC § 6213; IRS, Understanding Your CP3219N Notice).

Even after the IRS prepares an SFR, filing your own accurate original return is usually the correct step. The IRS states that it will generally adjust the account to reflect the taxpayer’s correct income, deductions, exemptions, and credits (IRS, Filing Past Due Tax Returns).

Refund limitations still matter. A late-filed return may reduce an assessed balance even when the refund statute has expired, but the taxpayer may be unable to receive a refund for an older year outside the applicable claim period (IRC § 6511).

Part 3 : There’s a Significant Penalty Abatement Opportunity Going On Now

Penalty relief is available, but it is not automatic for every taxpayer or every year. The correct strategy depends on the penalty type, the tax period, your filing and payment history, and the facts that caused the delay (IRS, Administrative Penalty Relief).

1. First Time Abate

First Time Abate, or FTA, is an administrative waiver that may remove certain failure-to-file, failure-to-pay, or failure-to-deposit penalties when the taxpayer has a qualifying compliance history. The IRS generally reviews whether required returns were filed, whether taxes were paid or arranged for payment, and whether the taxpayer had a clean penalty history for the prior three years (IRS, Administrative Penalty Relief).

FTA is not a blanket waiver for all 2022 or 2023 penalties. It is evaluated for the specific taxpayer, tax period, and penalty, and using it strategically may matter when several years carry different penalty balances (IRM 20.1.1).

2. Reasonable cause

If FTA is unavailable, the IRS may consider reasonable-cause relief. The taxpayer must generally show that they exercised ordinary care and prudence but were nevertheless unable to file or pay on time, and that the failure was not due to willful neglect (IRC § 6651(a); IRS, Penalty Relief for Reasonable Cause).

Examples the IRS may consider include:

  • Serious illness, death, or incapacity.
  • Fire, natural disaster, or civil disturbance.
  • Inability to obtain essential records.
  • Certain IRS or electronic filing system problems.
  • Other documented circumstances showing responsible efforts to comply.

Lack of funds alone generally does not establish reasonable cause for failing to pay. A request should explain what happened, when it happened, how it prevented timely compliance, what corrective steps were taken, and what documents support the explanation (IRS, Penalty Relief for Reasonable Cause).

3. The new Automatic Exemption from Penalty process

The IRS announced the Automatic Exemption from Penalty, or AEP, in August 2026. For eligible original returns, the process applies to 2025 tax-year returns, 2026 quarterly returns, and future tax periods when the taxpayer has filed and paid on time for the preceding three years, or for 12 consecutive quarters in the case of quarterly filers (IRS, Automatic Penalty Relief Process).

AEP may automatically prevent certain failure-to-file, failure-to-pay, and failure-to-deposit penalties. It does not eliminate unpaid tax, interest, or penalties outside the AEP rules, and the IRS sends a confirmation notice when relief is applied (IRS, Administrative Penalty Relief).

A critical clarification: there is no broad automatic IRS penalty waiver for all failure-to-file or failure-to-pay penalties from tax years 2022 and 2023. Those years generally require an individual evaluation for FTA, reasonable cause, or another specific relief provision (IRS, Administrative Penalty Relief).

For an unfiled 2025 return, filing now can help establish compliance and may allow AEP to apply if all eligibility requirements are met. Do not wait for automatic relief before filing; AEP is applied after an eligible original return completes processing, and it does not replace the obligation to file or pay (IRS, Automatic Penalty Relief Process).
