What to Do If the IRS Says You Owe Them Money

If the IRS says you owe money, start by confirming the notice is genuine, then check the amount against your own return before deciding whether to dispute it or pay. The IRS contacts taxpayers about balances due by mail, not by email, text, or social media, so anything arriving through those channels is a scam.¹ Once you know the letter is real, the deadline printed on it is the thing to protect. Missing it costs you appeal rights and opens the door to bank levies and wage garnishments.²

Check the Numbers Before You Do Anything Else

Every IRS notice has a code in the upper right corner that tells you what the agency thinks happened and what your response window is. A CP14 says you filed but underpaid.³ A CP2000 says the income on your return doesn’t match what employers or banks reported.⁴ A CP3219N is a formal Notice of Deficiency, which starts a 90-day clock to petition the U.S. Tax Court.⁵ Different codes carry different deadlines, so identify yours before you plan a response.

Pull your return for the year in question and compare it line by line. Does the adjusted gross income match? Are your credits and deductions reflected? Was every payment you made during the year applied to the right period? If the notice flags unreported income, gather your W-2s, 1099s, and brokerage statements and check whether a form went to the IRS that never reached you. Mistakes cut both ways. Employers file corrected forms that the IRS misses, and payments get applied to the wrong tax year.

If the IRS Is Wrong

Most notices come with a tear-off response page. Mark the items you disagree with, write a clear explanation, and attach copies (never originals) of bank statements, corrected 1099s, canceled checks, or whatever supports your position. Mail it to the address on the notice. Most notices give you 30 days.⁶

If the IRS reviews your response and still disagrees, you can ask for a supervisor or a conference with the IRS Independent Office of Appeals. If that also fails, the agency will issue a formal Notice of Deficiency. That notice gives you 90 days to file a petition with the U.S. Tax Court, or 150 days if you’re outside the country.⁵ Petitions are filed through the court’s DAWSON system or by mail.⁷ The important consequence of filing on time: while your case is pending in Tax Court, the IRS cannot collect the disputed amount. Miss the 90 days and you lose that shield.

If the IRS has already sent a Notice of Intent to Levy or filed a federal tax lien, you have a separate right to challenge those collection actions. File Form 12153 within 30 days of the notice date to request a Collection Due Process hearing with the Office of Appeals. Miss that window and you can still request an equivalent hearing within one year, but you lose the option to take the case to Tax Court afterward.⁸

If the Amount Is Right but You Can’t Pay in Full

The IRS offers two payment plans, and setting one up matters beyond the convenience of monthly payments: once you enter an approved installment agreement and are current on filing, the failure-to-pay penalty rate drops by half.⁹

Short-Term Payment Plan

If your combined balance of tax, penalties, and interest is under $100,000, you can get up to 180 extra days to pay in full at no setup cost.¹⁰ Penalties and interest keep accruing during the extension, but there is no fee to enter the plan, and you can apply online.

Long-Term Installment Agreement

For balances up to $50,000, you can spread payments over as many as 72 months.¹⁰ The monthly amount has to be large enough to pay off the balance within that window. This qualifies for streamlined processing, so the IRS won’t demand detailed financial disclosures. You propose a payment amount and a start date.¹¹

Setup fees depend on how you apply and pay:

Online with direct debit: $22
Online without direct debit: $69
Phone, mail, or in-person with direct debit: $107
Phone, mail, or in-person without direct debit: $178
Low-income taxpayers: $43, and may be reimbursed

The cheapest path is online with direct debit.¹⁰ Direct debit also protects you from a missed payment, which can default the agreement and trigger immediate collection. The IRS Online Payment Agreement tool sets up either plan without a phone call or mailing. If you owe more than $50,000, or want to apply on paper, use Form 9465.¹²

If You Can’t Pay Anything Right Now

Payment plans assume you can afford a monthly payment. When even a small amount would leave you unable to cover rent or groceries, there are two options that don’t require monthly payments.

Currently Not Collectible Status

Ask the IRS to place your account in Currently Not Collectible status if paying anything would prevent you from meeting basic living expenses. The IRS will require a Collection Information Statement listing income, expenses, and assets. If the numbers confirm genuine hardship, collection activity pauses: no levies, no garnishments. The debt itself doesn’t disappear. Interest and penalties keep accruing, and the IRS reviews your finances periodically to see whether things have improved. The 10-year collection deadline continues to run in the background, which sometimes works in the taxpayer’s favor.¹³

Offer in Compromise

An Offer in Compromise settles your tax debt for less than the full amount when the IRS concludes that’s the most it can reasonably expect to collect. Applications use Form 656 along with Form 433-A (OIC), a detailed disclosure of every asset, account, and income source in your household.¹⁴ 15 The IRS measures your expenses against its published Collection Financial Standards, which cap allowable costs for food, housing, and transportation by family size and location.¹⁶ Anything above those standards needs documentation.

The application fee is $205, plus an initial payment with your offer. Low-income taxpayers can skip both. Thresholds for that waiver are $37,650 for a single person and $78,000 for a family of four in the contiguous states.¹⁷¹⁸ The IRS rejects most offers, and incomplete financial disclosures are the fastest way to a denial.

Penalties and Interest

The number on your notice is almost never just the original tax. Two penalties and interest stack on top:

Failure-to-file penalty: 5% of the unpaid tax per month or partial month, up to 25%. If the return is more than 60 days late, the minimum is $525 or 100% of the tax, whichever is less.¹⁹
Failure-to-pay penalty: 0.5% of the unpaid tax per month, capped at 25%. Drops to 0.25% per month once you enter an approved installment agreement, if the return was filed on time.⁹
Interest: charged on both unpaid tax and accumulated penalties. For 2026, the rate for individual underpayments is 7% per year, compounded daily. Interest cannot be waived; it runs from the original due date until the balance is paid.²⁰

Penalties, unlike interest, can often be reduced or removed, and this is where most taxpayers leave money on the table because they don’t know to ask.

First-Time Abatement

If you filed all required returns on time and had no penalties during the previous three years, you can ask the IRS to waive your failure-to-file or failure-to-pay penalty for the current period.²¹ It applies regardless of the amount, and you request it by calling the number on your notice or writing a letter. The IRS won’t offer it on its own.

Reasonable Cause Relief

If first-time abatement isn’t available, you can still request relief by showing you had a legitimate reason for not complying. The IRS considers whether you exercised ordinary care and prudence and was still unable to meet your obligations. Situations that typically qualify include serious illness, a death in the family, destruction of records by fire or natural disaster, or reliance on incorrect advice from the IRS itself. Send documentation with the request.

If Your Spouse Caused the Problem

If you filed a joint return and your spouse understated income or claimed bogus deductions without your knowledge, you may not be responsible for the resulting balance. There are three forms of relief, all requested through Form 8857:²²

Innocent Spouse Relief, if the understatement came from errors you didn’t know about and a reasonable person in your position wouldn’t have caught.
Separation of Liability Relief, if you’re now divorced, legally separated, or no longer living with your spouse, so you’re responsible only for your share.
Equitable Relief, a catch-all where neither of the other two fits but holding you responsible would be unfair.

Requests must be filed within two years of the IRS’s first collection attempt for the understated amount. Victims of domestic abuse who signed under pressure may qualify even if they technically knew about the errors.²²

If the Notice Looks Like Identity Theft

If the balance is based on income from an employer you’ve never worked for, someone likely used your Social Security number to file. The IRS sometimes flags suspicious filings itself with Letters 5071C, 4883C, or 5747C. If you get one, use the online verification tool or call the number on the letter to confirm your identity and tell the IRS you didn’t file that return.²³

If you discover the theft on your own, file Form 14039 (Identity Theft Affidavit) and attach it to a paper return. Don’t file Form 14039 if you already received a Taxpayer Protection Program letter, because that verification process handles it. Identity theft cases currently take an average of 623 days to resolve.²³

When to Bring in Help

Most balance-due and income-mismatch notices can be handled without a professional. An Offer in Compromise, a large disputed assessment, or an audit that keeps escalating usually changes that calculus. Attorneys, certified public accountants, and enrolled agents can represent you before the IRS once you file Form 2848 (Power of Attorney).²⁴ Enrolled agents are licensed by the IRS itself, specialize in tax matters, and typically cost less than attorneys or CPAs for collection work. Rates vary; get quotes from more than one.

If you’ve exhausted the normal IRS channels or the agency’s actions are causing real financial hardship, the Taxpayer Advocate Service is an independent office within the IRS that can step in. Request assistance with Form 911. TAS help is free, and advocates can escalate cases, override certain actions, and move stalled matters forward.²⁵ Every state has at least one local TAS office, and it’s the right destination when you’ve been waiting months on a case and can’t get answers through the regular phone lines.
