If you don't file taxes for four years, the IRS can assess penalties and interest, file a Substitute for Return (SFR) on your behalf (which often costs you deductions), seize assets through liens and levies, and even pursue prosecution for willful evasion, though the latter is rare; you lose any potential refund, and your tax bill grows with penalties (up to 25% of tax owed) and interest, with the IRS having a long time to collect, potentially up to 10 years or more after assessment.
Willful failure to file a tax return is a crime, which could lead to your arrest, prosecution, and, if you are convicted, penalties including jail time and tens of thousands of dollars in fines. You will also gain a criminal record, which could have untold damage to your career and reputation.
According to Section 139(8A) of the Income Tax Act, you are allowed to do so within four years from the end of the relevant assessment year. The IT department can issue a notice under Section 142(1) or 148 for non-filing. Heavy penalties, interest, and even prosecution may apply.
If you haven't filed taxes in years, gather your financial documents (income statements, receipts) for those years, request wage and income transcripts from the IRS to ensure accuracy, and file all missing returns ASAP, as the IRS prefers compliance over pursuing criminal action, even if you can't pay immediately; file to claim refunds (within 3 years) and avoid bigger penalties, and then contact the IRS for payment options like installment agreements if needed.
You risk losing your refund if you don't file your return. If you are due a refund for withholding or estimated taxes, you must file your return to claim it within 3 years of the return due date. The same rule applies to a right to claim tax credits such as the Earned Income Credit.
The 7 year rule
No tax is due on any gifts you give if you live for 7 years after giving them - unless the gift is part of a trust. This is known as the 7 year rule.

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.
If you don't file taxes for five years, you will forfeit all refunds that are over three years old (if applicable).
