What happens when the IRS denies or reduces your refund

The IRS can reduce your refund, deny it entirely, or offset it against other debts you owe — and when they do, you have the right to challenge that decision. The appeal process is free and does not require a lawyer, though it moves slowly. Most appeals take between four months and two years, depending on the complexity of your case and how backed up the IRS office handling it happens to be.

You cannot appeal a refund decision until you have received a formal notice from the IRS. That notice will be either a CP notice (a computer-generated letter about a specific issue) or a 30-day letter (which gives you 30 days to respond before the IRS closes the case). If you have received neither, contact the IRS at 800-829-1040 to confirm the status of your return.

The reason for the denial matters. Common reasons include a mismatch between your tax return and IRS records (W-2s, 1099s, income reported by employers), a claim for a refundable credit you do not meet the requirements for, or an offset to cover back taxes, child support, or federal student loan debt. Each reason has a different appeal path.

Key Takeaways

  • You must receive a formal IRS notice before you can appeal — either a CP notice or a 30-day letter — and you have 30 days from the date on that letter to respond.
  • The IRS Office of Appeals is a separate division from the office that denied your refund, and they will reconsider your case if you submit a written protest within the 30-day window.
  • If the IRS offset your refund to cover a debt you do not believe you owe, you can request a hearing through the Federal Offset Program, which has different timelines than a standard appeal.
  • You can represent yourself in an appeal, but if your case involves complex tax law or large amounts, a tax professional or attorney may improve your chances.
  • If you disagree with the Appeals Office decision, you can file a case in Tax Court, District Court, or the Court of Federal Claims — but you must exhaust the IRS appeal first in most situations.

How to file a written protest within 30 days

When you receive a 30-day letter, the clock starts when ready. You have 30 calendar days from the date on the letter to submit a written protest to the IRS Office of Appeals. Do not wait — if the 30 days pass, you lose the right to appeal within the IRS system and your only option becomes filing in court.

Your protest must be in writing. A phone call or email to the IRS does not count. Send a letter to the address listed on your 30-day notice (it will be a specific Appeals Office, not the main IRS office). Your letter should include your name, address, Social Security number or employer identification number, the tax year in question, and a clear statement that you are requesting an appeal to the Office of Appeals.

Explain why you disagree with the IRS decision. This does not need to be a legal argument — it can be a straightforward explanation of the facts as you understand them. For example: "The IRS says I claimed a child tax credit for a dependent who does not meet the requirements, but my daughter lived with me for the entire year and I provided more than half her support." Include copies of any documents that support your position: pay stubs, receipts, bank statements, letters from employers, custody agreements, or anything else that backs up your claim.

Mail your protest certified mail with return receipt requested. Keep a copy for your records. The IRS will send you a confirmation letter within a few weeks acknowledging receipt and assigning your case to an Appeals Officer.

What to expect during the Appeals Office review

The Appeals Office is separate from the IRS office that denied your refund. An Appeals Officer will review your case from scratch, looking at both the IRS position and yours. They are not bound by the original decision, and they do have authority to reverse it or reduce the amount owed.

You may be asked to provide additional documents or to participate in a conference — either in person, by phone, or by video. The Appeals Office will tell you what they need. If you are asked to attend a conference, you can bring a representative (a tax professional, attorney, or accountant) or attend alone. You do not need to hire anyone; the conference is meant to give you a chance to explain your side.

The Appeals Officer will issue a written decision, called a Notice of Appeals Conference Decision or a Notice of information. This decision explains the reasoning and tells you whether your refund is being restored, partially restored, or denied. If you disagree with this decision, you then have the option to file in court.

If the IRS offset your refund to pay another debt

An offset is different from a denial. The IRS took your refund and applied it to a debt — usually back taxes, unpaid child support, or defaulted federal student loans. The IRS does this automatically without asking your permission first.

You can challenge an offset through the Federal Offset Program. You have 60 days from the date the IRS notifies you of the offset to request a hearing. The hearing is conducted by an independent hearing officer, not by the IRS office that made the offset decision.

To request a hearing, send a written request to the address listed on your offset notice. State that you dispute the debt or that you believe you are not responsible for it. For example, if the offset is for child support you believe you have paid, include proof of payment. If the offset is for back taxes from a year you believe you do not owe, explain why.

The hearing officer will review the evidence and issue a decision. If they find that you do not owe the debt, the IRS will restore your refund. If they find that you do owe it, the offset stands, but you may then have other options depending on what the debt is (for instance, you can request a payment plan for back taxes, or you can contest a child support information through family court).

Filing in court if you disagree with the Appeals decision

If the Appeals Office denies your refund and you still disagree, you have three options: Tax Court, U.S. District Court, or the U.S. Court of Federal Claims. Each has different rules about timing, cost, and what types of cases they hear.

Tax Court is the most common choice for refund disputes. You must file a petition within 90 days of receiving the Appeals Office decision. Tax Court does not require you to pay the disputed amount first, and you do not need a lawyer. You can represent yourself, though the process is formal and involves written briefs and oral arguments. Filing a petition costs nothing, but if you lose, you may be ordered to pay the IRS's court costs.

U.S. District Court requires you to pay the full disputed amount first, then file a refund suit. You have two years from the date you paid the tax to file. District Court cases are more expensive and more formal than Tax Court, and most people hire an attorney. The advantage is that you can have a jury trial if you want one.

U.S. Court of Federal Claims also requires you to pay first, and you have two years to file. This court specializes in money claims against the federal government. Like District Court, it is formal and most people hire an attorney.

Before filing in any court, confirm that you have exhausted the IRS appeal process. If you filed a protest and received an Appeals Office decision, you have exhausted it. If you filed a protest but never received a decision (sometimes the IRS takes years), you may be able to file in court anyway — consult a tax attorney about your specific situation.

How long the process takes and what it costs

The IRS appeal process is free. You do not pay a fee to file a protest or to have the Appeals Office review your case. However, if you hire a tax professional or attorney to help you, you will pay their fees.

Timing varies widely. A straightforward case — for example, a mismatch between your return and a W-2 that you can resolve with one document — might be decided in four to six months. A complex case involving multiple issues or missing documents can take one to two years or longer. The Appeals Office is chronically understaffed, and backlogs are common.

If you file in court, the timeline depends on which court and how busy it is. Tax Court cases typically take one to three years from filing to decision. District Court and Court of Federal Claims cases often take longer.

During the appeal process, the IRS will not take further action on your case — they will not send collection notices or garnish your wages. However, if you owe back taxes (as opposed to a refund dispute), interest and penalties continue to accrue while you appeal.

When to hire a tax professional or attorney

You can handle a refund appeal yourself. Many people do, especially if the issue is straightforward and the amount is not large. However, a tax professional or attorney may be worth the cost if your case involves complex tax law, if the IRS is claiming you owe a large amount, or if you have already tried to resolve the issue and gotten nowhere.

A Certified Public Accountant (CPA) or Enrolled Agent (EA) can represent you before the IRS and the Appeals Office. They charge hourly rates that vary by location and experience, typically between $150 and $400 per hour. A tax attorney can do everything a CPA or EA can do, plus represent you in court. Attorneys usually charge more, but if your case goes to court, their informed in legal procedure becomes more valuable.

If you cannot afford a professional, you may be able to get free or low-cost help from a Low Income Taxpayer Clinic (LITC). These are nonprofit organizations funded by the IRS to help people with limited income. You can find one in your area at the IRS website or by calling 211.

Frequently Asked Questions

What if I missed the 30-day important date to file a protest?

If you missed the important date, you have lost the right to appeal within the IRS system. Your only option is to file a case in court — either Tax Court (within 90 days of the Appeals Office decision, if you received one), District Court, or Court of Federal Claims. You will need to pay the disputed amount first if you choose District Court or Court of Federal Claims. Consult a tax attorney about your options.

Can I appeal if the IRS says I owe money instead of getting a refund?

Yes, the same process applies. If the IRS says you owe additional tax, you will receive a 30-day letter and can file a written protest to the Appeals Office. The appeal process is identical whether the dispute is about a refund or about money owed.

What if I disagree with the Appeals Office decision?

You can file a case in Tax Court, District Court, or Court of Federal Claims. Tax Court is usually the best choice because you do not have to pay the disputed amount first and you do not need a lawyer. You have 90 days from the date of the Appeals Office decision to file a Tax Court petition.

Does the IRS have to respond to my protest letter?

Yes. The IRS must acknowledge receipt of your protest within a few weeks and assign your case to an Appeals Officer. If you do not hear from them within 30 days, contact the Appeals Office listed on your 30-day letter to confirm they received it.

Can I appeal an offset if I do not think I owe the debt?

Yes. You have 60 days from the offset notice to request a hearing before an independent hearing officer. You do not go through the standard Appeals Office process for an offset — the Federal Offset Program has its own hearing system. Submit your request in writing to the address on your offset notice and explain why you believe you do not owe the debt.
