How to File My Taxes Late and What Happens Next

Missing a tax deadline can feel overwhelming, but it is a common situation many taxpayers face. While the initial deadline for filing and paying taxes has passed, there are clear, actionable steps available to address the situation. Taking prompt action can help minimize potential penalties and interest that may accrue on unpaid taxes.

Understanding Late Filing Consequences

Failing to file a tax return by the due date, or an approved extended due date, can result in penalties and interest charges. The Internal Revenue Service (IRS) imposes a “failure to file” penalty under Internal Revenue Code Section 6651, which amounts to 5% of the unpaid taxes for each month or part of a month the return is late. This penalty is capped at a maximum of 25% of the unpaid tax.

Separately, a “failure to pay” penalty is assessed under Internal Revenue Code Section 6651 when taxes are not paid by the due date. This penalty is 0.5% of the unpaid taxes for each month or part of a month the tax remains unpaid, also capped at 25% of the unpaid taxes.

Interest also accrues on unpaid taxes and unpaid penalties, compounding daily. This interest rate is determined quarterly and is typically the federal short-term rate plus three percentage points for individuals. For example, for the first quarter of 2025, the interest rate for underpayments for individuals is 7% per year, compounded daily.

The failure-to-file penalty is generally much more substantial than the failure-to-pay penalty. For instance, if a return is more than 60 days late, the minimum failure-to-file penalty can be the lesser of $485 or 100% of the tax owed. This significant difference emphasizes the importance of filing a tax return, even if the tax liability cannot be paid in full by the due date.

Steps to File a Delinquent Return

When a tax return is past due, the immediate priority is to prepare and submit it accurately. Gathering all necessary income statements, such as W-2s and 1099s, and expense records is essential to ensure the return reflects the correct tax liability. Once the return is complete, the focus shifts to the proper submission method.

For the most recent past tax year, e-filing may still be an option through commercial tax software or a tax professional. This method often provides confirmation of receipt, which can be valuable. However, for older tax years, electronic filing capabilities generally become unavailable, necessitating a paper submission.

Mailing a paper return requires the return to be signed and dated, and it is crucial to send it to the correct IRS address. Using certified mail with a return receipt provides proof of mailing and delivery, establishing a record of compliance. This documentation can be helpful if any questions arise later regarding the timely submission of the delinquent return. Filing the return as quickly as possible helps stop the accrual of the significant failure-to-file penalty.

Addressing Unpaid Tax Liabilities

If a tax return is filed and a tax liability is determined, but immediate full payment is not possible, several options are available to address the unpaid amount. The simplest approach, if funds become available, is to pay the full amount owed. However, when this is not feasible, the IRS offers various arrangements to help manage the debt.

A short-term payment plan may be available for taxpayers who need a brief period, typically up to 180 days, to pay their tax liability in full. While this plan provides a temporary reprieve, interest and penalties continue to accrue during this period.

For those needing more time, an Installment Agreement under Internal Revenue Code Section 6159 allows for monthly payments over an extended period, generally up to 72 months. Setting up such an agreement involves a small fee, and taxpayers must remain compliant with future filing and payment obligations.

For taxpayers facing significant financial hardship, an Offer in Compromise (OIC) under Internal Revenue Code Section 7122 may be an option. An OIC is an agreement with the IRS to resolve a tax liability for a lower amount than what is originally owed. Eligibility for an OIC is typically based on doubt as to collectibility or doubt as to liability. This option requires a comprehensive financial disclosure and careful consideration, as it is generally for those with limited ability to pay.

Circumstances for Penalty Abatement

The IRS may reduce or remove penalties under specific circumstances, a process known as penalty abatement. This is a formal request that can be made through various channels, including by phone, letter, or by submitting Form 843, Claim for Refund and Request for Abatement. Form 843 can be used for requesting abatement of penalties and interest, particularly when related to IRS errors or reasonable cause.

One ground for penalty abatement is “reasonable cause,” as outlined in Internal Revenue Code Sections 6651 and 6724. This applies when a taxpayer can demonstrate they exercised ordinary business care and prudence but were still unable to comply with tax obligations due to circumstances beyond their control. Examples of situations that may qualify for reasonable cause include natural disasters, serious illness or death of the taxpayer or an immediate family member, unavoidable absence, or the inability to obtain necessary records. It is important to provide supporting evidence for any claims of reasonable cause.

Another common avenue for penalty relief is the First-Time Abate (FTA) policy. This administrative relief is generally available for failure-to-file, failure-to-pay, and failure-to-deposit penalties. To qualify for FTA, a taxpayer typically must have a clean compliance history for the preceding three tax years. Additionally, all required returns must have been filed, and any tax due must have been paid or arrangements made to pay it. While both reasonable cause and FTA can provide relief, they have distinct criteria that must be met for a successful abatement request.
