How to check what you owe the IRS

You can learn about you owe the IRS by logging into your account on IRS.gov, calling the IRS directly, or checking the mail for a notice. The IRS sends notices when you owe, and these notices include the amount, what tax year it covers, and how to pay or dispute it. If you have not received a notice but think you might owe, the IRS online account tool is the fastest way to see your balance.

To use the IRS online tool, go to IRS.gov and select "View your tax account" under the "Taxes" section. You will need to verify your identity — usually with your Social Security number, date of birth, and filing status. Once you log in, you can see any balance owed, payment history, and notices the IRS has sent you. This tool updates daily and shows your current balance in real time.

If you prefer to speak with someone, you can call the IRS at 1-800-829-1040. Wait times are often long, especially during tax season, but the IRS can tell you your balance over the phone. Have your Social Security number, filing status, and any recent tax documents ready when you call.

What an IRS notice means

An IRS notice is an official letter that tells you the IRS believes you owe money. The notice includes the tax year, the amount owed, the reason (such as unpaid taxes, penalties, or interest), and a important date to respond. Most notices give you at least 30 days to act, though some allow longer. The notice also explains your options: you can pay, set up a payment plan, or request that the IRS review the amount.

Different notices mean different things. A Notice of Tax Due means you did not pay all the tax you owed when you filed. A Notice of Deficiency means the IRS examined your return and found additional tax owed. A Notice of Federal Tax Lien means the IRS has a legal claim on your property because of unpaid taxes. If you receive any notice, read it carefully and follow the instructions, because ignoring a notice can lead to wage garnishment or bank levies.

The notice will have a phone number and a reference number. If you do not understand the notice or disagree with it, you can call that number to ask questions. You can also request a Collection Due Process hearing if you want the IRS to review the debt before they take collection action.

Reasons the IRS says you owe

The most common reason is that you did not pay all the tax you owed when you filed your return. This happens when you did not have enough withheld from your paychecks or did not make estimated tax payments if you are self-employed. The IRS calculates what you should have paid based on your income, deductions, and credits, and if the amount you paid (through withholding or estimated payments) was less, you owe the difference.

The IRS may also say you owe because they examined your return and found errors. This is called an audit. The IRS might find that you claimed deductions you were not may have access to to, reported income incorrectly, or made a math error. If the IRS finds you owe more tax, they will send you a notice explaining what they found and how much additional tax you owe.

You may also owe penalties and interest. Penalties are charges for filing late, paying late, or underpaying estimated taxes. Interest is charged on any unpaid tax, starting from the original due date. Interest compounds daily, so the longer you wait to pay, the more you owe. The IRS charges interest at a rate set by law, which changes quarterly.

What to do if you disagree with the amount

If you believe the IRS made an error, you can request a review. The notice you receive will explain how to do this. Most notices give you the option to request a Collection Due Process hearing, which is a chance to tell the IRS why you disagree before they take collection action like garnishing your wages or levying your bank account. You must request this hearing within the important date shown on the notice, usually 30 days.

You can also contact the IRS directly to discuss the debt. Call the number on your notice and explain why you think the amount is wrong. Have any documents that support your position ready — such as receipts, bank statements, or copies of payments you made. If the IRS made a math error on your return, they may correct it without needing a hearing.

If you want professional help reviewing the debt, you can hire a tax professional, accountant, or attorney. Some offer free initial consultations. The IRS also has a Taxpayer Advocate Service, which is a free service within the IRS that can help if you are having trouble resolving a dispute or if the IRS is not responding to your requests.

Payment options if you owe

If you owe and want to pay right away, you can pay in full online, by phone, or by mail. The IRS accepts credit cards, debit cards, electronic bank transfers, and checks. You can pay online at IRS.gov under "Payments" — this is usually the fastest method. If you pay by phone, call 1-800-829-1040. If you mail a check, make it payable to "United States Treasury" and include your Social Security number and the tax year on the check.

If you cannot pay the full amount right now, you can set up a payment plan. The IRS offers two types: a short-term extension (up to 180 days to pay) and an installment agreement (monthly payments over a longer period). You can request a payment plan online, by phone, or by mail. The IRS charges a setup fee and may charge interest and penalties while you are paying, but a payment plan stops the IRS from taking collection action like wage garnishment.

If you are having serious financial hardship, you may be able to request Currently Not Collectible status. This temporarily pauses collection action while you work to improve your financial situation. Interest and penalties still accrue, but the IRS will not garnish your wages or levy your bank account. You will need to show the IRS that you cannot pay without causing hardship.

What happens if you do not pay

If you owe and do not pay or set up a payment plan, the IRS can take collection action. This starts with notices and phone calls, but can escalate to wage garnishment (the IRS tells your employer to send part of your paycheck to the IRS), bank levies (the IRS takes money directly from your bank account), or a tax lien (the IRS places a legal claim on your property). These actions can seriously damage your finances and credit.

The IRS also charges failure-to-pay penalties and interest while the debt sits unpaid. The failure-to-pay penalty is usually 0.5% of the unpaid tax per month, up to 25% total. Interest is charged daily and compounds, so the longer you wait, the more you owe. If you owe a large amount and do not act, the debt can grow significantly.

If the IRS places a tax lien on your property, it becomes public record and can harm your credit score. A lien means the IRS has a legal claim on your home, car, and other assets. Even if you sell the property later, the IRS can claim the proceeds to pay the debt. A lien stays on your record for 10 years unless you pay the debt sooner or reach an agreement with the IRS.

Getting help from the Taxpayer Advocate Service

The Taxpayer Advocate Service is a free service within the IRS that helps people who are having trouble with the IRS. You can contact them if the IRS is not responding to your requests, if you disagree with a debt and cannot resolve it on your own, or if you are facing financial hardship because of the debt. The Advocate Service is independent from the IRS collection division, so they can look at your situation objectively.

To reach the Taxpayer Advocate Service, call 1-877-777-4778 or visit taxpayeradvocate.irs.gov. You can also ask for help from your local Advocate office — there is one in every state. The Advocate Service can request that the IRS pause collection action while they review your case, and they can help you understand your options and rights.

Frequently Asked Questions

How do I know if the IRS actually sent me a notice or if it is a scam?

The IRS always sends notices by mail, never by email, text, or phone call. If someone calls claiming to be from the IRS and threatening arrest or when ready payment, it is a scam. Real IRS notices have your name, address, a reference number, and specific details about your tax account. If you are unsure, call the IRS directly at 1-800-829-1040 using the number on your notice or on IRS.gov — do not use a number from the suspicious message.

Can the IRS take my tax refund if I owe?

Yes. If you owe back taxes or other federal debts, the IRS can use your refund to pay what you owe. This is called offset. The IRS will send you a notice explaining this before it happens. If you are owed a refund but the IRS offsets it, you will receive a notice showing how much was taken and why.

What if I cannot afford to pay and do not have a payment plan?

Contact the IRS and explain your situation. You may be able to request Currently Not Collectible status, which pauses collection action temporarily. You can also ask about a payment plan that fits your budget, or contact the Taxpayer Advocate Service for help. The key is to contact the IRS before they take action — ignoring the debt makes it worse.

Does owing the IRS hurt my credit score?

A tax debt itself does not appear on your credit report. However, if the IRS places a tax lien on your property, that becomes public record and can harm your credit. Also, if the IRS sends your debt to a collection agency, that collection account will appear on your credit report and lower your score.

How long does the IRS have to collect a debt from me?

The IRS generally has 10 years from the date they assess the tax to collect it. However, certain actions — like filing for bankruptcy or requesting a Collection Due Process hearing — can pause this time limit. After 10 years, the IRS can no longer collect the debt, though you may still owe it to the state or other creditors.
