Not filing taxes is illegal if you owe money or meet the filing threshold

If your income exceeds the filing threshold set by the IRS for your age and filing status, you are required by law to file a tax return. The threshold varies by year and depends on whether you are claimed as a dependent, your age, and your type of income. Not filing when you are required to do so is a violation of federal tax law, even if you do not owe any tax.

The IRS distinguishes between two separate violations: failing to file and failing to pay. Failing to file carries its own penalties and can result in criminal charges if the IRS determines the failure was willful. Failing to pay — when you file but do not pay what you owe — carries different penalties. Both can accumulate interest and lead to wage garnishment, bank levies, or liens against your property.

The consequences depend on how long you have not filed, whether the IRS has contacted you, and whether you owe money. A person who has not filed for one year faces different consequences than someone who has not filed for five years.

Key Takeaways

  • You must file a tax return if your income exceeds the IRS threshold for your age and filing status, even if you expect to owe nothing.
  • The IRS can assess a failure-to-file penalty of up to 5 percent per month of unpaid tax, capped at 25 percent, separate from penalties for not paying.
  • If you have not filed in multiple years, the IRS will eventually contact you, and the longer you wait the larger the accumulated penalties and interest become.
  • Criminal prosecution for tax evasion is rare but possible if the IRS finds evidence of willful intent to break the law, not simple negligence or inability to pay.
  • Filing late, even years late, stops additional penalties from accruing and is always better than continuing not to file.

Who is required to file a tax return

The IRS sets a filing threshold each year based on your filing status, age, and type of income. For 2024, a single person under 65 with only wage income must file if their gross income was $14,600 or more. A single person 65 or older must file if their gross income was $18,150 or more. These thresholds are higher for married couples filing jointly and lower for dependents.

The threshold is different if you are self-employed. If you had net earnings from self-employment of $400 or more, you must file even if your total income is below the standard threshold. This applies whether you are a sole proprietor, freelancer, or gig worker.

You must also file if you had tax withheld from your paychecks or made estimated tax payments, even if your income falls below the threshold. Filing allows you to claim a refund of that withheld money. If you received income from sources other than wages — such as interest, dividends, or rental income — the threshold may be lower or different.

Civil penalties for not filing

The IRS assesses a failure-to-file penalty if you do not file by the deadline and you owe tax. The penalty is 5 percent of the unpaid tax for each month or part of a month that the return is late, up to a maximum of 25 percent. This penalty is separate from the failure-to-pay penalty and separate from interest.

If you file more than 60 days late, the minimum penalty is the smaller of $435 (for 2024) or 100 percent of the unpaid tax. This means that even if you owe a small amount, a very late filing can result in a penalty equal to what you owe.

Interest accrues on unpaid tax from the original due date until you pay. The interest rate is set quarterly by the IRS and is currently in the range of 8 to 9 percent per year. Interest compounds daily. A person who has not filed for five years will owe not only the original tax but also five years of accumulated interest and penalties.

These penalties do not apply if you did not owe any tax. If your income was below the filing threshold and you had no tax withheld, there is no penalty for not filing — though you may still want to file to claim a refund if you had tax withheld or are due a refundable credit like the Earned Income Tax Credit.

What happens when the IRS contacts you

The IRS does not immediately pursue every person who does not file. If you owe a small amount or have no income, you may not hear from them for years. However, the IRS has computer systems that match income reported by employers and financial institutions to filed returns. If you received a W-2 or 1099 form and did not file, the IRS will eventually notice.

The IRS typically begins with a notice by mail asking you to file. This notice includes the amount the IRS calculated you owe based on the income it has on record. You have a deadline to respond — usually 30 days. If you do not respond, the IRS can file a substitute return on your behalf using only the income it knows about. A substitute return does not include deductions or credits you could claim, so it often results in a higher tax bill than you would owe if you filed yourself.

After a substitute return is filed, the IRS can begin collection actions. This includes sending your account to a collection agency, placing a lien on your property, garnishing your wages, or levying your bank account. These actions continue to accrue interest and penalties until the debt is paid or resolved through a payment plan or settlement.

Criminal prosecution for tax evasion

Criminal prosecution for not filing is rare. The IRS pursues criminal cases only when it finds evidence of willful intent to break the law — meaning you knew you were required to file and deliberately chose not to. Simple negligence, inability to pay, or not understanding the rules is not enough for criminal charges.

Tax evasion — the criminal charge most commonly associated with not filing — requires proof that you took deliberate steps to hide income or deceive the IRS. Examples include operating an unreported cash business, hiding income in offshore accounts, or destroying records. Not filing alone, without evidence of active concealment, is less likely to result in criminal charges than other tax crimes.

If the IRS does pursue a criminal case, it is typically after years of non-filing and after civil collection efforts have failed. Criminal prosecution is more common for high-income individuals or those with complex financial situations. A person convicted of tax evasion can face up to five years in prison and fines up to $250,000.

How to resolve unfiled tax years

If you have not filed for one or more years, the first step is to gather your documents: W-2 forms, 1099 forms, receipts for deductions, and any notices the IRS has sent you. You can request transcripts of the income the IRS has on record by calling the IRS at 1-800-829-1040 or using the IRS website.

File all unfiled years in order, starting with the oldest. You can file by mail or electronically if you use tax software or a tax professional. Filing late does not require special forms or procedures — you file the same return you would have filed on time, with the understanding that penalties and interest will be added.

If you cannot pay the full amount owed, you can set up a payment plan with the IRS. A short-term plan (120 days or less) has no setup fee. A long-term installment agreement has a setup fee of $31 to $225 depending on how you pay. The IRS will work with you on a monthly payment amount based on your income and expenses.

If you are in financial hardship, you may be able to request Currently Not Collectible status, which temporarily pauses collection efforts while interest and penalties continue to accrue. This is not forgiveness — it is a pause that allows you to stabilize your finances before resuming payments.

Frequently Asked Questions

Can the IRS put me in jail for not filing taxes?

Criminal prosecution for not filing alone is uncommon. Jail time requires proof of willful intent to evade taxes, not simple failure to file. Civil penalties — fines, liens, and wage garnishment — are far more common. Criminal charges are typically pursued only in cases involving deliberate concealment of income or years of non-filing after the IRS has made repeated collection attempts.

What if I owe money but cannot pay right now?

File the return anyway. Filing stops the failure-to-file penalty from accruing and allows you to set up a payment plan. The IRS offers installment agreements with monthly payments as low as $25 in some cases. You can also request Currently Not Collectible status if you are in severe financial hardship, which pauses collection efforts temporarily.

How far back can the IRS go if I have not filed?

The IRS can go back as far as it wants to assess penalties and interest, but it typically focuses on the last six years. However, if you owe a large amount of tax, the statute of limitations is 10 years from the date the tax is assessed. Filing old returns does not erase the debt, but it stops additional penalties from accruing and may reduce the total amount owed.

Do I have to file if I made very little money?

If your income was below the filing threshold for your age and filing status, you are not required to file. However, if you had taxes withheld from your paychecks or made estimated payments, filing allows you to claim a refund. You may also be due refundable credits like the Earned Income Tax Credit, which requires filing to receive.

What if the IRS already filed a substitute return for me?

File your own return anyway. Your return will replace the substitute return, and you can claim deductions and credits the substitute return did not include. This may reduce the amount you owe. The IRS will adjust your account once your return is processed.
