If you owe federal taxes and don’t pay by the filing deadline, the IRS immediately starts adding a failure-to-pay penalty of 0.5% per month plus interest that compounds daily, currently at 7% a year. From there, the agency sends a series of notices, and if you ignore them, it can file a public tax lien, garnish your wages, seize bank accounts, and even have your passport revoked. What happens if you owe taxes depends almost entirely on whether you engage: the IRS has several formal ways to work with you, and it would rather set up a payment arrangement than chase you through enforcement.
How Fast the Balance Grows
The failure-to-pay penalty runs at 0.5% of your unpaid tax for each month or partial month the balance is outstanding, up to a maximum of 25%.1Office of the Law Revision Counsel. 26 USC 6651 Failure to File Tax Return or to Pay Tax On top of that, interest accrues from the original due date of the return at the federal short-term rate plus three percentage points, set quarterly.2Office of the Law Revision Counsel. 26 USC 6621 Determination of Rate of Interest For the first quarter of 2026, that rate is 7%, compounded daily.3Internal Revenue Service. Quarterly Interest Rates Interest also accrues on unpaid penalties, so a modest tax bill can grow well past its original size in a couple of years.
Not filing is punished much more harshly than not paying. The failure-to-file penalty is 5% per month, also capped at 25%, and if your return is more than 60 days late, the minimum penalty for returns due in 2026 is $525 or 100% of the tax owed, whichever is less.4Internal Revenue Service. Failure to File Penalty5Internal Revenue Service. Topic No. 653, IRS Notices and Bills, Penalties and Interest Charges So if you owe money you can’t pay, file anyway. Filing without paying costs you 0.5% a month. Not filing costs you ten times that.
Two rate adjustments are worth knowing about. If the IRS sends a final notice of intent to levy and you still don’t act, the failure-to-pay rate doubles to 1% per month.1Office of the Law Revision Counsel. 26 USC 6651 Failure to File Tax Return or to Pay Tax But if you filed on time and set up an installment agreement, the rate drops to 0.25% per month for the duration of that agreement.
The Notice Sequence Before Enforcement
The IRS doesn’t skip straight to seizing anything. It sends a structured series of notices, and knowing where you are in the sequence tells you how much time you have.
The first is a CP14, the official demand for payment showing the tax owed plus any accrued penalties and interest and a deadline to pay.6Internal Revenue Service. Understanding Your CP14 Notice If the CP14 goes unanswered, follow-up reminders (CP501, then CP503) arrive over the following months with progressively firmer language.
The one that should stop you cold is the CP504. It’s the final notice of intent to levy, meaning the IRS is telling you it will begin seizing assets if you don’t respond. The CP504 is also what triggers the penalty rate increase from 0.5% to 1% per month, and it starts the clock on your right to request a formal hearing before the IRS can move against your property.
Federal Tax Liens
Once the IRS makes demand for payment and you don’t pay, a federal tax lien automatically attaches to everything you own, including real estate, vehicles, financial accounts, and any assets you acquire while the debt remains unpaid.7Office of the Law Revision Counsel. 26 USC 6321 Lien for Taxes The lien exists by operation of law. The IRS then files a public Notice of Federal Tax Lien to alert other creditors.
Since 2018, tax liens no longer appear on credit reports from the three major bureaus, so a lien alone won’t sink your credit score. But the public filing shows up in title searches, which can block you from selling or refinancing property, and lenders doing due diligence will find it. Getting a mortgage while a federal tax lien is active is extremely difficult.
Levies, Wage Garnishment, and What’s Protected
A lien is a legal claim. A levy is the IRS actually taking your property. If the debt remains unresolved after the notice sequence, the IRS can seize funds from your bank account, garnish your wages, and sell real estate or vehicles.8Office of the Law Revision Counsel. 26 USC 6331 Levy and Distraint A bank levy freezes the funds in your account on the date the levy hits. Wage garnishment continues every paycheck until you satisfy the debt or reach a resolution.
Federal law exempts some property from levy, including necessary clothing and schoolbooks, household goods and personal effects up to $6,250, tools of your trade up to $3,125, unemployment and workers’ compensation benefits, court-ordered child support you pay from wages, and certain public assistance and disability payments.9Office of the Law Revision Counsel. 26 USC 6334 Property Exempt from Levy Your principal residence is also protected, though the IRS can override that exemption with written approval from a senior official. A portion of your wages is exempt as well, calculated from the standard deduction and the number of dependents you claim.
Passport Revocation
If your total tax debt (including penalties and interest) exceeds $66,000, the IRS can certify you to the State Department as seriously delinquent. The State Department will then deny a new passport application and may revoke your existing passport.10Internal Revenue Service. Revocation or Denial of Passport in Cases of Certain Unpaid Taxes The threshold is adjusted annually for inflation.11Office of the Law Revision Counsel. 22 USC 2714a Revocation or Denial of Passport in Case of Certain Unpaid Taxes
You won’t be certified if you’re on a payment plan, have a pending offer in compromise, or have requested a Collection Due Process hearing. If you’ve already been certified and then enter into one of those arrangements, the IRS will reverse the certification. In emergencies or humanitarian situations, the State Department retains discretion to issue a limited passport for return travel to the United States.
How to Stop the Escalation
Several formal resolution paths exist, and picking one halts collection activity.
Installment Agreements
A payment plan is the most common resolution. A short-term plan gives you up to 180 days to pay in full with no setup fee, available for balances under $100,000 in combined tax, penalties, and interest. A long-term installment agreement lets you make monthly payments over a longer period and is available online for balances of $50,000 or less.12Internal Revenue Service. Payment Plans; Installment Agreements
Setup fees vary by application method and payment type. Applying online and paying by direct debit is the cheapest route at $22, and low-income taxpayers can have the fee waived entirely. For balances above $50,000, or terms the online tool can’t accommodate, you file Form 9465 with a Collection Information Statement detailing your income, assets, and expenses.13Internal Revenue Service. About Form 9465, Installment Agreement Request The IRS then uses national and local standards to decide what monthly payment you can afford.14Internal Revenue Service. Collection Financial Standards Once your agreement is active and if you filed on time, the failure-to-pay penalty drops to 0.25% per month.
Offer in Compromise
An offer in compromise lets you settle your tax debt for less than the full amount. The IRS considers each offer case by case, weighing your income, expenses, and asset equity against how much it could realistically collect.15Internal Revenue Service. Offer in Compromise The agency rejects more offers than it accepts and will only agree when collecting the full amount is unlikely or would cause genuine hardship.
To apply, you have to be current on all required filings and estimated payments, and you can’t be in an active bankruptcy. The application costs $205 plus an initial payment (20% of the offer for a lump-sum, or the first monthly installment if you’re paying periodically). Low-income taxpayers are exempt from both. Review typically takes six months to a year, during which most collection activity is paused. If your offer is rejected, any payments you made are applied to your balance and not returned.
Currently Not Collectible Status
If your income barely covers basic living expenses, you may qualify for Currently Not Collectible status. This pauses all IRS collection activity on your account. You still owe the debt, and interest and penalties continue to accrue, but the IRS won’t levy wages or seize accounts while the status is in effect.16Internal Revenue Service. 5.16.1 Currently Not Collectible Procedures You’ll need to submit a financial statement showing that any payment would prevent you from meeting reasonable living expenses. The IRS periodically reviews these accounts and can reactivate collection if your income rises.
Penalty Relief
Penalties themselves can sometimes be removed. First-Time Abatement is available if you filed the same type of return for the three prior years, had no penalties during that period, and are current on all required filings.17Internal Revenue Service. Administrative Penalty Relief You request it by calling the IRS or writing a letter. Reasonable cause relief is separate and requires documentation of a legitimate reason (fire, natural disaster, serious illness or death in the family, inability to obtain records, or a system failure that delayed an electronic filing).18Internal Revenue Service. Penalty Relief for Reasonable Cause Interest, unlike penalties, is rarely waived and generally runs until the balance is paid.
The 30-Day Hearing Right
Before the IRS files a lien or levies your property, it must notify you and tell you about your right to a Collection Due Process hearing. You have 30 days from that notice to request the hearing by filing Form 12153.19Internal Revenue Service. Collection Due Process (CDP) FAQs Collection activity is suspended while your request is pending.
At the hearing, held by the IRS Office of Appeals independently of collections, you can challenge whether procedures were followed, propose an installment agreement or offer in compromise, and in some cases dispute the underlying tax. If you disagree with the outcome, you can petition the U.S. Tax Court. Miss the 30-day window and you can still request an equivalent hearing, but you lose Tax Court access and collection isn’t paused. Put the deadline on a calendar.
The 10-Year Collection Deadline
The IRS doesn’t have unlimited time. Once a tax is assessed, the agency has 10 years to collect through levy or court action.20Office of the Law Revision Counsel. 26 USC 6502 Collection After Assessment After that Collection Statute Expiration Date passes, the debt is legally unenforceable and the IRS must stop pursuing it.21Internal Revenue Service. Time IRS Can Collect Tax
The clock can pause. Bankruptcy, a pending offer in compromise, a Collection Due Process hearing request, or six continuous months living outside the country all suspend the 10-year period. An installment agreement can extend it by the length of the agreement plus 90 days. If the deadline expires while you’re in Currently Not Collectible status, the debt simply goes away. That makes running out the clock a real strategy for some people, but only if you know exactly when the clock started and what has paused it.
