The penalty for not paying your federal taxes starts at 0.5% of your unpaid balance every month, plus interest that compounds daily from the original due date until the debt is gone. That is only the opening move. Left alone, an unpaid tax bill can grow past 25% in penalties, attract a federal tax lien on everything you own, trigger seizure of your bank account or paycheck, cost you your passport, and in the worst cases lead to criminal charges. Almost all of that is avoidable if you deal with the IRS before it escalates.
The Monthly Penalty and How It Grows
If you owe tax and don’t pay by the filing deadline, the IRS charges a failure-to-pay penalty of 0.5% of the unpaid balance for each month or partial month the debt sits.1Office of the Law Revision Counsel. 26 USC 6651 – Failure to File Tax Return or to Pay Tax – Section: (a) Addition to the Tax On a $10,000 balance that’s $50 a month. The penalty keeps stacking until it hits 25% of the original unpaid amount, which on that same $10,000 tops out at $2,500.
Two things change the rate. If the IRS sends a notice of intent to levy and you still don’t pay, the monthly rate doubles to 1%.2Office of the Law Revision Counsel. 26 USC 6651 – Failure to File Tax Return or to Pay Tax Going the other direction, if you set up an installment agreement and filed your return on time, the rate drops to 0.25% per month. That reduced rate alone can save hundreds of dollars over the life of a moderate balance, which is why calling the IRS early is one of the most underrated moves in tax debt management.
You can escape the penalty entirely if the failure was due to reasonable cause rather than neglect, and the IRS also offers a one-time waiver called First Time Abate for taxpayers who have filed on time and stayed penalty-free for the prior three years.3Internal Revenue Service. Administrative Penalty Relief If you qualify, the penalty is wiped as if it never existed.
Interest That Never Stops
On top of penalties, the IRS charges interest on every unpaid dollar starting from the original due date of the return, whether or not you got a filing extension.4Office of the Law Revision Counsel. 26 USC 6601 – Interest on Underpayment, Nonpayment, or Extensions of Time for Payment, of Tax Unlike penalties, interest has no cap and compounds daily. The longer you wait, the faster the balance grows.
The rate is set quarterly and equals the federal short-term rate plus three percentage points.5Office of the Law Revision Counsel. 26 USC 6621 For the second quarter of 2026 the individual underpayment rate was 6% per year.6Internal Revenue Service. Internal Revenue Bulletin 2026-8 Because the rate adjusts every three months, a debt carried across several years accrues interest at several different rates along the way.
Interest also runs on unpaid penalties once the IRS sends you a bill and 21 days pass without payment. Compounding then works on the full stack: the tax, the penalty, and interest on both. This is the single biggest reason tax debts spiral. A modest balance left alone for a few years can grow by 50% or more before any collection action even starts.
File Even If You Cannot Pay
Skipping the return itself is treated far more harshly than skipping the payment. The failure-to-file penalty runs at 5% of the unpaid tax for each month your return is late, capped at 25%.2Office of the Law Revision Counsel. 26 USC 6651 – Failure to File Tax Return or to Pay Tax That is ten times the failure-to-pay rate.
When both penalties apply in the same month, the IRS reduces the filing penalty by the 0.5% payment penalty, so the combined charge is 5% per month for the first five months.7Internal Revenue Service. Failure to File Penalty After five months the filing penalty maxes out at 25% and the payment penalty keeps accruing on its own. The practical takeaway: filing a return you can’t fully pay is dramatically cheaper than ignoring the deadline.
When the IRS Takes Your Property
Two different tools let the government reach your assets, and they work in sequence.
The first is a federal tax lien. Once the IRS assesses your tax, sends a bill, and you don’t pay within the required timeframe, a lien automatically attaches to everything you own, including property you acquire later.8Office of the Law Revision Counsel. 26 USC 6321 – Lien for Taxes That covers real estate, vehicles, bank accounts, and business equipment. The lien itself is automatic, but the IRS can also file a Notice of Federal Tax Lien in your local public records, which can wreck your ability to get a mortgage, sell property, or qualify for credit. Once you pay in full, the IRS must release the lien within 30 days.9Internal Revenue Service. Understanding a Federal Tax Lien
The second tool is a levy, which is the IRS actually taking property rather than just claiming a legal interest. After sending a final notice of intent to levy and waiting at least 30 days, the IRS can seize bank accounts, garnish wages, and take physical assets without going to court.10Office of the Law Revision Counsel. 26 USC 6331 – Levy and Distraint
Bank levies freeze the funds in your account on the day they hit. The bank holds that money for 21 days, giving you a narrow window to contact the IRS before it’s turned over.11Internal Revenue Service. Information About Bank Levies Wage levies are continuous: a portion of every paycheck is diverted to the IRS until the debt is cleared or you reach an agreement.12Internal Revenue Service. Levy Social Security benefits and retirement accounts can also be levied, with certain amounts exempt for basic living expenses.
If you receive a levy notice, you have 30 days to request a Collection Due Process hearing, which pauses the seizure while your case is reviewed.13Internal Revenue Service. Collection Due Process (CDP) FAQs Missing that window doesn’t kill your appeal rights entirely, but it does cost you the ability to challenge the levy in Tax Court afterward.
Losing Your Passport
A large enough tax bill can ground your international travel. When your seriously delinquent tax debt exceeds $66,000 (the inflation-adjusted threshold for 2026), the IRS certifies your account to the State Department.14Office of the Law Revision Counsel. 26 USC 7345 – Revocation or Denial of Passport in Case of Certain Tax Delinquencies15Internal Revenue Service. Revocation or Denial of Passport in Cases of Certain Unpaid Taxes That figure includes assessed penalties and interest, so an underlying tax well below $66,000 can push you over once the extras pile on.
Once certified, the State Department will generally refuse to issue or renew your passport, and may revoke an existing one. To reverse the certification you need to pay the balance in full, enter an approved installment agreement, or have the IRS accept an Offer in Compromise. When the underlying issue is resolved, the IRS decertifies your account and notifies State to lift the restriction.
When Nonpayment Becomes Criminal
Most tax disputes stay civil. The IRS refers cases for prosecution when it can prove willful behavior, meaning you deliberately tried to cheat rather than simply fell behind. The distinction between “I couldn’t pay” and “I hid income to avoid paying” is the line between a penalty letter and a federal indictment.
Tax evasion is the most serious charge. It is a felony carrying up to five years in federal prison and fines up to $100,000 for individuals ($500,000 for corporations), plus the costs of prosecution.16Office of the Law Revision Counsel. 26 USC 7201 – Attempt to Evade or Defeat Tax The government has to prove you knew you owed taxes and took deliberate steps to avoid paying.
A lesser charge, willful failure to pay, is a misdemeanor punishable by up to one year in prison and fines up to $25,000 for individuals.17Office of the Law Revision Counsel. 26 USC 7203 – Willful Failure to File Return, Supply Information, or Pay Tax Either conviction creates a permanent criminal record. The criminal penalties don’t replace the civil ones. You still owe the tax, interest, and civil penalties on top of any criminal fines.
How Long the IRS Can Chase You
The IRS generally has 10 years from the date it assesses your tax to collect what you owe, including penalties and interest. This is called the Collection Statute Expiration Date.18Internal Revenue Service. Time IRS Can Collect Tax Once that window closes, the debt is legally uncollectible and any remaining liens must be released.
Certain actions pause the clock. Filing for bankruptcy, submitting an Offer in Compromise, requesting a Collection Due Process hearing, or living outside the country can all suspend the 10-year period. Each tax assessment carries its own separate expiration date, so if you owe for several years, some debts may expire before others.
How to Stop the Meter
The IRS would rather collect something than chase you through liens and levies. Several formal programs exist for taxpayers who can’t pay in full.
Short-Term Payment Plans
If you can pay within 180 days, you can set up a short-term plan with no setup fee when you apply online. Penalties and interest still run on the outstanding balance, but more aggressive collection is off the table. Individual taxpayers who owe less than $100,000 in combined tax, penalties, and interest can apply online.19Internal Revenue Service. Payment Plans; Installment Agreements
Long-Term Installment Agreements
For larger debts, a monthly installment agreement spreads payments over a longer period. Online applications are available for individual taxpayers who owe $50,000 or less in combined tax, penalties, and interest.19Internal Revenue Service. Payment Plans; Installment Agreements Setup fees depend on how you apply and how you pay:
- Direct debit from a checking account: $22 online, $107 by phone or mail
- Manual monthly payments: $69 online, $178 by phone or mail
- Low-income taxpayers: the fee is waived for direct debit plans and reduced to $43 for manual plans
Setting up an installment agreement carries a bonus. As long as you filed on time, the monthly failure-to-pay penalty drops from 0.5% to 0.25%.2Office of the Law Revision Counsel. 26 USC 6651 – Failure to File Tax Return or to Pay Tax
Offer in Compromise
An Offer in Compromise lets you settle for less than you owe. The IRS accepts these when the offered amount represents the most it can realistically expect to collect from you. Eligibility requires that you’ve filed all required returns, aren’t in bankruptcy, and have made any required estimated tax payments.20Internal Revenue Service. Offer in Compromise The application costs $205, and you must include an initial payment (either a lump-sum deposit or your first monthly installment). Low-income taxpayers who meet certain guidelines are exempt from both the fee and the initial payment.
Currently Not Collectible Status
If paying anything at all would leave you unable to cover basic living expenses, you can ask the IRS to designate your account Currently Not Collectible. Active collection pauses, though interest and penalties keep accruing and the IRS may still file a lien to protect its claim. Importantly, the 10-year collection clock keeps running during this time.
Getting Penalties Removed
Penalties aren’t always final. If you’ve filed the same type of return for the past three tax years, received no penalties during that period, and are current on all filings, you can request First Time Abate.3Internal Revenue Service. Administrative Penalty Relief It’s an administrative waiver, requested by phone or letter, that applies to failure-to-pay, failure-to-file, and failure-to-deposit penalties.
When you don’t qualify for First Time Abate, you can still ask the IRS to remove penalties by showing reasonable cause. The IRS evaluates circumstances like serious illness, natural disasters, the death of an immediate family member, inability to access records, or system issues that blocked timely electronic filing.21Internal Revenue Service. Penalty Relief for Reasonable Cause The standard is showing that you exercised ordinary care and prudence and still couldn’t meet the deadline. “I forgot” and “I didn’t have the money” generally don’t qualify.
One boundary worth knowing: penalty abatement removes penalties only. Interest on the underlying tax isn’t eligible for abatement outside very narrow exceptions for IRS errors, and it will keep running until the balance is paid.
