A tax waiver is one of two things depending on context: an IRS decision to remove a penalty it assessed against you, or a state-issued clearance certificate confirming that taxes owed on a deceased person’s assets have been paid. For IRS penalties, you can request a waiver by phone, by filing Form 843, or in a written letter, and you generally qualify under one of three grounds — a clean compliance history (First-Time Abatement), reasonable cause, or an IRS error that caused the problem. For estate matters, the waiver is issued by a state revenue department and is what banks, brokerages, and title companies wait for before releasing a deceased person’s property.
Which type applies to you determines everything else about the process, so it’s worth separating them from the start.
First-Time Abatement: The Easiest Waiver to Get
If a late-filing or late-payment penalty is your first in several years, the First-Time Abatement program is usually the fastest way out. You don’t need an excuse. You need a clean record.1Internal Revenue Service. Administrative Penalty Relief
Three conditions have to be met:
- No penalties were assessed in the three tax years before the year at issue (or any that were assessed were removed for a valid reason other than First-Time Abatement).
- You filed the same type of return in each of those three prior years when required.
- You’ve filed the return that triggered the penalty, or at least filed a valid extension.
A point that trips people up: you do not have to have paid the underlying tax to qualify. You can request First-Time Abatement while still carrying a balance.1Internal Revenue Service. Administrative Penalty Relief
The program covers failure-to-file penalties, failure-to-pay penalties, and business failure-to-deposit penalties. It does not cover estimated tax penalties, event-based filing penalties, or information reporting penalties.1Internal Revenue Service. Administrative Penalty Relief If you underpaid quarterly estimated taxes, you need the reasonable-cause route instead.
Reasonable Cause: When Something Genuinely Got in the Way
Reasonable cause is the broader path. The statute requires you to show your failure to comply wasn’t due to willful neglect.2Office of the Law Revision Counsel. 26 USC 6651 – Failure to File Tax Return or to Pay Tax In practice, the IRS wants to see that you used ordinary care and still fell short because of something outside your control.
Circumstances the IRS recognizes include:
- Death or serious illness of you or an immediate family member.
- Natural disasters or fires that destroyed your records.
- Inability to obtain records despite genuine effort.
- System outages that prevented electronic filing or payment.3Internal Revenue Service. Penalty Relief for Reasonable Cause
What the IRS Actually Wants to See
A one-line explanation will not work. The Internal Revenue Manual sets out what examiners weigh in each type of claim.4Internal Revenue Service. IRM 20.1.1 Introduction and Penalty Relief
For illness or death, the examiner looks at the dates and severity, how the event actually prevented filing or paying, whether your other obligations were disrupted during the same period, and whether you handled taxes promptly once you were able. Attach hospital records, a doctor’s note with dates, or a death certificate, and pair them with a timeline showing when you resumed normal affairs.
For missing records, the examiner considers what steps you took to obtain them, when you realized they were gone, whether you explored alternatives, and why you didn’t file using estimates. Copies of letters requesting records and any responses you received carry weight. Simply waiting and hoping does not.4Internal Revenue Service. IRM 20.1.1 Introduction and Penalty Relief
Lack of Funds by Itself Is Not Enough
Inability to pay, standing alone, is not reasonable cause for the failure-to-pay penalty. You also have to show you exercised ordinary business care in providing for payment — that you tried to secure funds, considered borrowing, and paid as soon as money became available.4Internal Revenue Service. IRM 20.1.1 Introduction and Penalty Relief One narrow exception: if you filed for bankruptcy before the payment was due, the IRS will treat inability to pay as a relevant factor.
Accuracy-Related Penalties Use a Different Standard
If the penalty was for understating income or claiming deductions you weren’t entitled to, the standard shifts from ordinary care to “reasonable cause and good faith.”3Internal Revenue Service. Penalty Relief for Reasonable Cause The IRS weighs the complexity of the issue, your background with tax matters, the effort you made to report correctly, and whether you sought professional help. If you relied on an advisor, expect scrutiny of whether you gave that advisor all relevant information and whether the advisor was competent for your situation. Handing documents to a preparer and hoping for the best will not carry this claim.
How to Request the Waiver
There are three routes, and the right one depends on how complex your claim is.
By Phone
For straightforward requests, especially First-Time Abatement, call the toll-free number on your IRS notice. Have the notice, the specific penalty, and your reasons in front of you. The agent can approve relief on the call. If they cannot, they’ll tell you to submit a written request.5Internal Revenue Service. Penalty Relief
By Mail Using Form 843
For reasonable-cause claims that need documentation, put it in writing. Use IRS Form 843, Claim for Refund and Request for Abatement, if you’ve already paid the penalty and want a refund. The form asks for the tax period, the type of tax, and the exact dollar amount you’re challenging.6Internal Revenue Service. Instructions for Form 843 Attach a letter that walks through your circumstances and everything supporting them — medical records, a disaster declaration, correspondence showing your attempts to obtain records, whatever fits your claim. Current versions of federal forms are available at irs.gov.7Internal Revenue Service. About Form 843, Claim for Refund and Request for Abatement
Send everything by certified mail to the address on your notice. Keep the receipt. Processing usually takes around 60 days, though complex cases can run to three months.
Deadlines
If the penalty is unpaid and you’re asking for it to be abated, there’s no statutory deadline. You can request relief at any time. If you’ve already paid and want a refund, the window is three years from the date you filed the return or two years from the date you paid the penalty, whichever is later.8Internal Revenue Service. IRM 25.6.1 Statute of Limitations Processes and Procedures After that, the IRS cannot legally issue the refund.
What Happens to Interest
Interest accrues on penalties from the date they’re assessed. When a penalty is reduced or removed, the interest on that penalty is automatically reduced or removed too. You do not need a separate request.5Internal Revenue Service. Penalty Relief
Interest on the underlying unpaid tax is different. Even if every penalty is wiped clean, interest on the tax itself keeps accruing until you pay the balance. A waiver lowers the bill; it does not freeze it.
In narrow situations, the IRS can also abate interest on the underlying tax when an IRS employee’s unreasonable error or delay caused it to accumulate. This applies only to ministerial or managerial acts — procedural tasks — not to how the tax law was applied to your case. The abatement covers only the period after the IRS first contacted you in writing about the deficiency, and no significant part of the delay can be your fault.9Internal Revenue Service. Abatement and Suspension of Underpayment Interest Separately, if the IRS gave you incorrect written advice in response to a specific question, any penalty from following that advice must be abated.10Office of the Law Revision Counsel. 26 USC 6404 – Abatements Keep the original letter.
If the IRS Denies Your Request
A denial is not the end. The rejection letter will spell out your appeal rights, and you generally have 30 days from the date on that letter to request a hearing with the IRS Independent Office of Appeals.11Internal Revenue Service. Penalty Appeal
Your written appeal should include a copy of the denial letter and a detailed explanation of why the penalty should come off. If you’re arguing that you filed on time, include proof such as a certified mail receipt. If you’re arguing reasonable cause, provide the same kinds of records described above, and sharpen the letter to directly answer whatever the IRS gave as its reason for denial.
For interest abatement specifically, if the IRS denies your claim or doesn’t respond within 180 days, you can petition the U.S. Tax Court to review whether the agency abused its discretion. The petition must be filed within 180 days of the IRS’s final determination letter.10Office of the Law Revision Counsel. 26 USC 6404 – Abatements
Estate Tax Waivers Are a Different Animal
When someone dies, the federal government and certain states may have a claim against the estate’s assets. An estate tax waiver, sometimes called a clearance certificate or tax release, is the document that confirms those obligations have been settled or that none are owed. It is what banks and title companies wait for before releasing accounts, transferring securities, or closing on real estate.
At the federal level, the estate tax applies to estates valued above $15,000,000 in 2026, a threshold set by the One, Big, Beautiful Bill Act signed into law on July 4, 2025.12Internal Revenue Service. What’s New – Estate and Gift Tax If the estate must file Form 706, a federal lien attaches to the property, and selling real estate from the estate may require applying for a lien discharge before closing.13Internal Revenue Service. Sell Real Property of a Deceased Person’s Estate
At the state level, a handful of states impose their own inheritance or estate taxes, and several require a waiver before assets can be released. The forms, thresholds, and procedures vary widely. Some states require waivers on every estate regardless of value; others only above certain thresholds. Financial institutions in these states typically freeze accounts and refuse to transfer securities until they receive the state-issued clearance.
If you’re administering an estate, contact the department of revenue or treasury in the state where the deceased person lived. That agency will tell you which forms to file and whether the estate falls under the threshold. Finding out about a waiver requirement at the moment you’re trying to close on a property sale or access funds for funeral expenses is a common and avoidable problem.
Preparing Your File Before You Submit
Whichever waiver you’re pursuing, preparation is what separates approvals from denials. For a penalty request, pull the specific tax period, the type of tax, and the exact penalty amount off the IRS notice before you start writing.6Internal Revenue Service. Instructions for Form 843 Your explanation should tie your circumstances directly to the legal standard: for reasonable cause, show exactly how the event blocked compliance and what you did as soon as you could act; for First-Time Abatement, a short letter is fine, since you’re relying on your record. For estate clearance, gather the death certificate, the estate’s tax returns, and proof of payment for any taxes owed before you approach the state agency.
