Not filing taxes is very bad, leading to significant financial penalties (5% monthly failure-to-file penalty plus interest, up to 25% of unpaid taxes), potential liens and levies on wages/assets, loss of refunds/credits, and even criminal prosecution for willful evasion, including fines and jail time, plus the IRS can file a substitute return for you, creating a tax bill you'd still owe penalties on. It's crucial to file, even if you can't pay, to avoid severe consequences.

What happens if you don't file taxes?

If you don't file taxes when required, the IRS imposes significant penalties and interest, starting with a 5% late-filing penalty (up to 25% of tax owed), plus a failure-to-pay penalty (0.5% per month), and interest on the total amount due, which can lead to wage garnishment, tax liens on property, seizure of assets, and even criminal charges in severe cases, though the primary consequences are financial penalties and collection actions. If you're owed a refund, there are no penalties for filing late, but you must file to claim it.

Will the IRS catch me if I don't file?

Yes, the IRS will come after you for not filing taxes, eventually leading to penalties, interest, collections like liens or levies, and potentially criminal prosecution if you persistently refuse, as there's no statute of limitations for unfiled returns, allowing them to pursue you indefinitely. They can even file a Substitute for Return (SFR) for you, creating a tax bill, and begin a 10-year collection period. 

How long can you legally go without filing taxes?

There's no official limit to how many years you can go without filing taxes, but the IRS expects you to file if required, and the statute of limitations on the IRS assessing tax or collecting never starts until you actually file, meaning they can pursue unfiled returns from any year, even decades old. While the IRS often focuses on the last six years, waiting increases penalties and interest, and you risk losing any potential refunds after three years; proactively filing past-due returns is always best. 

Does IRS catch all mistakes?

No, you generally cannot skip a year of filing taxes if you meet the IRS filing requirements (income thresholds, self-employment earnings, etc.), as it's a legal obligation that can lead to significant penalties and interest if you owe taxes, though you might not need to file if your income is below the standard deduction and you have no other filing triggers.
