What Happens When You Miss an IRS Deadline: Practical Next Steps

Immediate consequences: penalties, interest, and timeframes

If you miss an IRS deadline you may face three linked problems: a late-filing penalty, a late-payment penalty, and interest on any unpaid tax. The late-filing penalty is generally 5% of the unpaid tax for each month (or part of a month) the return is late, up to a 25% maximum. The late-payment penalty is usually 0.5% per month up to 25% (both applied to unpaid tax). Interest accrues on unpaid tax and penalties and compounds daily; the IRS sets the rate quarterly as the federal short-term rate plus 3% (IRS, Interest Rates).

• Source: IRS, “Penalties” and IRS, “Interest rates” pages (see https://www.irs.gov and https://www.irs.gov/fees/interest-rates).

Note: specific minimum penalties apply if a return is filed more than 60 days late. The minimum late-filing penalty is the lesser of a set dollar amount or 100% of the tax due; amounts change periodically, so check the IRS penalties page for the current dollar thresholds.

What to do first (short checklist)

1. File immediately — even if you can’t pay. Filing halts the growing late-filing penalty and preserves options such as refunds or credits. If you are due a refund, there’s no penalty for filing late, but you must file within three years to claim it (IRS, Time Limits).
2. Pay as much as you can now. That reduces the base that penalties and interest are calculated on.
3. Review the notice. If the IRS sent a notice, read it carefully — it usually states what happened, any balances, and the next steps.
4. Set up a payment method. Online payment options include Electronic Federal Tax Payment System (EFTPS), Direct Pay, and credit/debit cards.
5. Contact a tax professional if the amount or complexity is significant. In my practice I’ve seen timely professional help prevent liens and lower long-term costs.

Filing late vs. not filing: different outcomes

• If you owe taxes and don’t file: you face both late-filing and late-payment penalties plus interest. The late-filing penalty is usually larger, so file the return even if you can’t pay in full.
• If you don’t owe taxes (refund due): file as soon as possible; there’s no penalty, but you must file within three years to claim the refund.
• If you’re due a small refund but miss the deadline by a long time, you may forfeit the refund after the three-year window.

Extensions and when they help

Filing an extension (Form 4868 for individuals) extends the time to file the return but does NOT extend the time to pay tax due. If you file for an extension, estimate and pay any expected tax by the original due date to avoid the late-payment penalty. See IRS Form 4868 and instructions: https://www.irs.gov/forms-pubs/about-form-4868.

Payment relief and options

If you can’t pay in full, the IRS offers several options:

• Short-term payment plan: typically 120 days or less; no setup fee in many cases but interest and penalties continue.
• Long-term installment agreement: monthly payments; setup fees may apply unless you qualify for a streamlined or low-balance agreement. See details and online application guidance in FinHelp’s guide on applying for an installment agreement: How to Apply for an Installment Agreement Online: Step-by-Step.
• Offer in Compromise (OIC): an agreement to settle tax liability for less than the full amount. Qualification is strict and based on ability to pay, income, assets, and future earning potential.
• Currently Not Collectible (CNC) status: if you can show you have no ability to pay, the IRS may temporarily suspend collection but interest and penalties continue to accrue.

Penalty relief: reasonable cause and first-time abatement

Two common relief paths are First-Time Abatement (FTA) and reasonable cause penalty relief.

• First-Time Abatement: If you have a clean compliance history (no penalties for the prior three years) you may qualify for FTA for certain penalties. This is an administrative relief and is often granted when requested.
• Reasonable Cause: You can ask the IRS to waive penalties if you can show reasonable cause — examples include serious illness, natural disaster, death in the family, or inability to obtain records despite reasonable efforts. Documentation is critical: doctor’s notes, hospital records, insurance claims, or other proof strengthens the claim.

How to request relief: follow the instructions on the IRS notice or attach a written statement to your filed return explaining the facts. Professional representation can improve success rates.

Notices, liens, levies, and appeals

If the IRS doesn’t receive payment or acceptable arrangements, it will continue collection efforts. Common steps: Notice CP14 (balance due), repeated notices, then Notice of Intent to Levy, federal tax liens, and levies on bank accounts or wages.

• A lien is a public claim against your property. A levy is the actual seizure of assets or income.
• You have rights: the right to appeal collection actions and to request a Collection Due Process (CDP) hearing in many cases.

If you receive a notice, respond promptly. Ignoring notices accelerates enforcement and reduces your options.

Business and nonprofit considerations

• Businesses: payroll taxes are treated more severely. Trust fund recovery penalties and accelerated collection can apply; payroll tax liabilities are often a priority for the IRS.
• Nonprofits: failing to file required annual returns (e.g., Form 990) can lead to loss of tax-exempt status. Address late filings immediately to limit organizational damage.

Statute of limitations — assessment vs. collection

• Assessment: The IRS generally has three years from the date you file to assess additional tax. If you understate income by more than 25%, the window extends to six years. Fraud has no time limit.
• Collection: Once the IRS assesses a tax, it generally has 10 years to collect (collection statute expiration date or CSED). These timelines matter when negotiating resolution or when balancing negotiation vs. waiting for CSED.

Sources: IRS pages on assessment and collection timelines; confirm the specific dates on https://www.irs.gov if you face a case-specific timeline.

Practical examples and my experience

In practice I’ve seen two patterns: taxpayers who file late but communicate early, and those who ignore notices. The first group usually avoids liens and often secures manageable installment agreements. The second group commonly faces levies or higher fees. For example, a client missing two tax years who immediately filed and applied for a streamlined installment agreement avoided a bank levy and kept interest and penalties from growing worse.

How to prepare to negotiate with the IRS

• Gather documentation: returns, wage statements, bank statements, bills, and proof of hardship.
• Create a clear budget showing income, expenses, and ability to pay.
• Be honest and consistent in communications.
• Consider professional representation for complex or high-dollar accounts.

Common mistakes to avoid

• Waiting to file because you can’t pay. Filing protects you from larger late-filing penalties.
• Ignoring IRS notices. Silence removes options and speeds enforcement.
• Relying on inaccurate online calculators for penalties; use IRS notices and official calculators when possible.

Final checklist (action plan)

1. File the missing return(s) immediately. 2. Pay what you can now. 3. Set up an online payment agreement or request relief. 4. Compile supporting documents if you’ll request penalty abatement. 5. Respond in writing to IRS notices and keep copies. 6. Seek professional help for complex matters.
