What happens if you don’t file your taxes? It’s a question many taxpayers ask when they miss the tax deadline, discover an old unfiled return, or simply can’t afford the amount they owe.

The most important thing to know is this: ignoring an unfiled tax return generally doesn’t make the problem go away. If you’re required to file, taking action sooner rather than later can help limit penalties, interest, and other potential consequences.

At AIM Financial, we help taxpayers understand their obligations and take practical steps to address outstanding tax issues.

Do You Have to File a Tax Return?

Not everyone is required to file a federal income tax return every year. Filing requirements depend on factors such as income, filing status, age, dependency status, and certain types of income.

For example, the IRS generally requires taxpayers to file when their gross income reaches the applicable filing threshold. Self-employed individuals may have a filing requirement when they have $400 or more in net earnings from self-employment.

Even if you aren’t required to file, submitting a return may still be beneficial. You could be entitled to a refund because of federal income tax withheld from your paycheck or because you qualify for certain refundable tax credits.

What Happens If You Miss the Tax Deadline?

If you’re required to file and don’t submit your return by the deadline, the IRS may charge a failure-to-file penalty.

For individuals and most business tax returns, the failure-to-file penalty is generally 5% of the unpaid tax for each month or partial month the return is late, up to a maximum of 25%.

There can also be a separate failure-to-pay penalty when taxes remain unpaid.

That means taxpayers who both fail to file and fail to pay can potentially face multiple charges, along with interest that continues to increase the amount owed.

What If You Can’t Afford to Pay Your Taxes?

One of the biggest misconceptions about taxes is that you shouldn’t file if you don’t have enough money to pay the balance.

That’s generally the wrong approach.

If you owe taxes but can’t afford to pay the entire amount, filing your return can help prevent additional failure-to-file penalties from continuing to accumulate. The IRS offers payment options for taxpayers who cannot pay their balance in full.

Depending on your circumstances, you may be able to establish an installment agreement or explore other available options.

The key is to address both parts of the problem: file the required return and develop a plan for the balance due.

What If You Haven’t Filed for Several Years?

If you’ve missed more than one tax return, don’t assume that the situation is hopeless.

The best course of action is generally to determine which returns you’re required to file, gather your financial records, and begin getting those returns completed.

The IRS may send notices requesting delinquent returns. If you receive one, read it carefully and follow the instructions and deadlines provided.

Getting professional assistance can be especially helpful when multiple years, missing documents, self-employment income, investments, or previous IRS notices are involved.

Could You Lose a Tax Refund?

Yes. Waiting too long to file can potentially cause you to lose the opportunity to claim a refund or certain tax credits.

The IRS notes that federal tax law establishes strict time limits for claiming refunds and certain credits.

So even if you think you might be due money, delaying a required tax return can work against you.

Is There Any IRS Penalty Relief?

Possibly.

The IRS has introduced a new Automatic Exemption from Penalty (AEP) beginning in summer 2026 for certain eligible taxpayers with a history of timely filing and payment. Eligible taxpayers generally don’t need to request the relief when it applies.

Other penalty-relief provisions may also apply depending on the taxpayer’s circumstances. The IRS states that reasonable-cause relief can be available for certain penalties when a taxpayer can demonstrate that they exercised ordinary care and prudence but were unable to meet their tax obligations on time.

What Should You Do If You Haven’t Filed?

If you’re behind on your taxes, don’t let fear keep you from taking the first step.

Start by gathering your W-2s, 1099s, business records, investment documents, previous returns, and IRS correspondence. Then determine which returns are missing and whether you owe taxes or may be entitled to a refund.

The sooner you address an unfiled return, the more options you may have.
