If you don’t pay your federal taxes, the IRS starts charging penalties and daily-compounding interest the day after the return was due, sends a series of escalating notices, and eventually gains the power to file liens against your property, seize money from your bank account, garnish your wages, and block your passport once the debt exceeds $66,000. In rare willful cases, unpaid taxes can also lead to criminal charges. The agency has 10 years from the date of assessment to collect, and several formal programs can pause enforcement and resolve the debt along the way.
Penalties and Interest Start Immediately
Two separate penalties apply to late taxes, and they stack. The failure-to-file penalty is 5% of the unpaid tax for every month or part of a month the return is late, capped at 25%. The failure-to-pay penalty is smaller but relentless: 0.5% per month on any unpaid balance, also capped at 25%. When both apply in the same month, the filing penalty is reduced by the payment penalty, so the combined charge is 5% per month during those early months.1Office of the Law Revision Counsel. 26 U.S.C. 6651 – Failure to File Tax Return or to Pay Tax
Once you’re more than 60 days late, the minimum failure-to-file penalty jumps to the lesser of $525 or 100% of the tax owed.2Internal Revenue Service. Failure to File Penalty That floor means even a small balance can generate a disproportionate hit if it sits long enough. Both penalties can be waived only for “reasonable cause,” so being busy or forgetting doesn’t qualify.
Interest runs on top of all of this from the original due date of the return. The rate resets each quarter and equals the federal short-term rate plus three percentage points.3Office of the Law Revision Counsel. 26 U.S.C. 6621 – Determination of Rate of Interest For the first half of 2026, the underpayment rate was 7% in Q1 and 6% in Q2.4Internal Revenue Service. Quarterly Interest Rates Interest compounds daily and applies to accumulated penalties as well as the original tax, so a few months of inaction on a moderate balance can add hundreds or thousands of dollars.
The Notices You’ll Receive Before Anything Is Taken
The IRS doesn’t seize anything without warning. Collection starts with a CP501 balance-due reminder giving you a chance to pay or set up an arrangement.5Internal Revenue Service. Understanding Your CP501 Notice If you don’t respond, a CP503 restates the amount owed. Ignore that too, and a CP504 arrives labeled a Final Notice of Intent to Levy, warning that the IRS may begin seizing certain property, including state tax refunds.6Taxpayer Advocate Service. Notice CP501 – 1st Notice – Balance Due
The most important letter in the sequence is Letter 1058 (or its equivalent, LT11), a formal Final Notice of Intent to Levy and Your Right to a Hearing. You have 30 days from the date on that notice to file Form 12153 and request a Collection Due Process hearing. That request pauses enforcement and lets you propose alternatives. Miss the 30-day window and you lose the right to challenge the levy decision in Tax Court.7Taxpayer Advocate Service. Collection Due Process (CDP) Between 30 days and one year out, you can still request an equivalent hearing, but the result isn’t appealable to a court.
Liens Against Your Property
A federal tax lien is the government’s legal claim on everything you own. It arises automatically once the IRS assesses a tax, sends a demand for payment, and you don’t pay within the required period. The lien covers all property and rights to property, including real estate, vehicles, bank accounts, and even assets you acquire after it attaches.8Office of the Law Revision Counsel. 26 U.S.C. 6321 – Lien for Taxes
The lien itself doesn’t mean anything has been taken. The real damage comes when the IRS files a Notice of Federal Tax Lien in the public record. That filing alerts lenders, buyers, and credit agencies that the government has a senior claim, which makes getting a mortgage, refinancing, or selling a home extremely difficult.
A release is different from a withdrawal. A release means the debt itself is resolved: paid in full, settled through an Offer in Compromise, secured by a bond, or expired under the collection statute. A withdrawal only removes the public notice; the underlying lien remains and so does the debt. The IRS may withdraw a notice if you enter an installment agreement, if withdrawal helps you pay faster, or if the IRS didn’t follow proper filing procedures.9CCH AnswerConnect. IRS Publication 594 – The IRS Collection Process
Levies: When the IRS Actually Takes the Money
A levy is the seizure itself. The IRS can levy bank accounts, wages, retirement accounts, and physical assets like vehicles and real estate once it has followed the required notice procedures.10Office of the Law Revision Counsel. 26 U.S.C. 6331 – Levy and Distraint
Bank Account Levies
When the IRS levies a bank account, your bank freezes the funds up to the amount owed and holds them for 21 calendar days. You cannot withdraw the money during that period. If the IRS doesn’t release the levy within those 21 days, the bank sends the frozen funds on the next business day.11eCFR. 26 CFR 301.6332-3 – The 21-Day Holding Period Applicable to Property Held by Banks That 21-day window is your best chance to contact the IRS, show hardship, or arrange payment. Once the funds are gone, recovering them is far harder.
Wage Garnishments
A wage levy is continuous rather than one-time. The IRS notifies your employer and a portion of every paycheck goes straight to the IRS until the debt is paid or the levy is released. Unlike private creditors, the IRS doesn’t need a court order. The amount left to you depends on your filing status and number of dependents, and for many people it barely covers basic living expenses.
Physical Property
In the most extreme cases, the IRS can seize vehicles, real estate, and other tangible property for forced sale. Seizing a primary residence requires additional approval from a federal judge, and the agency generally reserves this for large, long-standing debts where the taxpayer has refused all other options. The statute exempts certain property from levy altogether, including a limited amount of personal belongings, unemployment benefits, workers’ compensation, and a portion of wages needed for basic living.
Your Passport Can Be Denied or Revoked
If your total tax debt, including penalties and interest, exceeds a threshold that adjusts for inflation each year, the IRS certifies you as “seriously delinquent” to the State Department. The threshold was $64,000 for 2025 and the IRS currently lists it at $66,000.12Internal Revenue Service. Revocation or Denial of Passport in Cases of Certain Unpaid Taxes Once certified, the State Department denies new passport applications and renewals.13Office of the Law Revision Counsel. 22 U.S.C. 2714a – Revocation or Denial of Passport in Case of Certain Unpaid Taxes
The government can also revoke an existing passport or limit it to return travel to the United States. The restriction stays until the IRS notifies the State Department that the debt is no longer seriously delinquent, which happens when you pay in full, enter a qualifying installment agreement, or reach another accepted resolution.
When Unpaid Taxes Become Criminal
Most people who fall behind face civil penalties, not criminal charges. But if the IRS believes you willfully tried to cheat, the consequences shift. Tax evasion, meaning deliberately underreporting income, hiding assets, or falsifying deductions, is a felony carrying up to five years in prison and a fine of up to $100,000 for individuals ($500,000 for corporations).14Office of the Law Revision Counsel. 26 U.S.C. 7201 – Attempt to Evade or Defeat Tax Willful failure to file a return is a separate misdemeanor with up to one year in prison.
“Willful” is doing the heavy lifting. Forgetting, making honest mistakes, or being negligent doesn’t typically trigger criminal prosecution. The IRS must prove you knew what the law required and deliberately chose to break it. Ignoring repeated notices and making no effort to resolve a debt does make willfulness easier for prosecutors to argue. Criminal tax cases are relatively rare, but the consequences are severe when they happen.
The 10-Year Collection Deadline
Federal law gives the IRS 10 years from the date a tax is assessed to collect it through levies or court proceedings. After that, the statute of limitations expires and the debt becomes legally unenforceable.15Office of the Law Revision Counsel. 26 U.S.C. 6502 – Collection After Assessment
The clock pauses in several situations, though. An installment agreement extends the collection period by the length of the agreement plus 90 days. Filing for bankruptcy, requesting a Collection Due Process hearing, or submitting an Offer in Compromise also suspends the countdown while those processes are pending. Actions taken to get relief can add years to the collection window, so it’s worth knowing when your 10-year clock started and what may have paused it before assuming a debt will expire on its own.
How to Stop the Escalation
The IRS would rather get paid something than chase you indefinitely. Qualifying for one of these formal programs also stops most enforcement while your case is under review.
Installment Agreements
If you owe $50,000 or less in combined tax, penalties, and interest, you can often qualify for a streamlined installment agreement without detailed financial statements.16Taxpayer Advocate Service. Owe Taxes But Can’t Pay the IRS in Full? Don’t Panic – You Have Options Monthly payments run over a set period, and the IRS holds off on levies and liens while the agreement is in place, though interest and penalties keep accruing. For larger debts, or when you can’t clear the full balance before the collection deadline, a Partial Payment Installment Agreement lets you pay what you can afford monthly, with any remaining balance written off when the 10-year period expires.17Taxpayer Advocate Service. Partial Payment Installment Agreement All required tax returns must be filed before the IRS will consider any installment agreement.
Offer in Compromise
An Offer in Compromise lets you settle for less than you owe. The IRS evaluates income, expenses, assets, and future earning potential to determine what it considers a reasonable collection amount. If the agency concludes it can’t collect the full balance within the remaining collection period, it may accept a reduced lump-sum or periodic payment. Low-income taxpayers can have the application fee and initial payment waived based on household size and income.18Internal Revenue Service. Form 656 Low-Income Certification Guidelines Acceptance rates are low, and offers that look like lowball attempts get rejected, so realistic financial documentation matters.
Currently Not Collectible Status
If paying anything toward the debt would prevent you from covering basic living expenses, the IRS can place your account in Currently Not Collectible status. You provide a financial statement (Form 433-A for individuals) showing your income and assets leave nothing available for payment. The IRS may waive the financial statement for debts under $50,000 if you’re terminally ill, incarcerated, living solely on Social Security or unemployment benefits, or have no income at all.19Internal Revenue Service. Currently Not Collectible Procedures Active collection stops, but interest and penalties keep accumulating, and the IRS reviews your situation at least every two years.
Getting Penalties Removed
Two paths exist to remove penalties even after they’ve been assessed. First Time Abate applies if you had a clean record for the prior three tax years, meaning all required returns filed and no penalties. The clean history itself qualifies you for a one-year waiver of the failure-to-file, failure-to-pay, or failure-to-deposit penalty; you don’t need to have paid the full balance first.20Internal Revenue Service. Administrative Penalty Relief
Reasonable cause is the other route. You argue that your failure was due to circumstances beyond your control rather than neglect. Serious illness, natural disasters, the death of an immediate family member, or a system failure preventing timely electronic filing generally qualify. Arguments that typically fail include not knowing the law, relying on a preparer who dropped the ball, simple mistakes, or lack of funds. Lack of funds alone is never reasonable cause for failing to pay, though it can be considered alongside other factors.21Internal Revenue Service. Penalty Relief for Reasonable Cause Neither path affects the underlying tax or interest.
Rights and Help Available
Federal law guarantees specific protections during collection. The Taxpayer Bill of Rights establishes ten fundamental rights, including the right to challenge IRS decisions and be heard, the right to appeal in an independent forum, and the right to finality — meaning the IRS must tell you the maximum time it has to audit a year or collect a debt.22Internal Revenue Service. Taxpayer Bill of Rights
The most powerful procedural right in collection is the Collection Due Process hearing. When you receive a Final Notice of Intent to Levy or a Notice of Federal Tax Lien filing, you have 30 days to request a hearing with the IRS Office of Appeals by filing Form 12153. Filing pauses enforcement and lets you propose alternatives; if you disagree with the Appeals decision, you can take the case to Tax Court. That court option disappears entirely if you miss the 30-day deadline.
If you’re facing economic harm, have waited more than 30 days for the IRS to resolve an issue, or believe an IRS system isn’t working properly, the Taxpayer Advocate Service can intervene. TAS operates independently from the rest of the IRS and can sometimes cut through delays that regular channels can’t.23Internal Revenue Service. Who May Use the Taxpayer Advocate Service Low-income taxpayers who can’t afford professional representation can also get free help from Low Income Taxpayer Clinics, which are funded by the IRS but run independently.
