To file a previous year's tax return online, use reputable tax software (e.g., FreeTaxUSA, H&R Block, or TaxAct) to prepare the forms for the specific tax year, then print and mail them, as the IRS generally does not allow e-filing for most prior-year returns. For the two most recent prior years, specialized software or tax professionals may be able to e-file.
Yes, you can file back taxes online for the current year and the two prior years using tax software like TaxAct, TurboTax, or FreeTaxUSA. However, for years beyond that, you generally must print, sign, and mail the returns to the IRS, as most self-preparation sites don't support e-filing older returns, though some tax professionals can e-file them for the last two years.

How to file previous years' taxes
The biggest tax mistakes people make include filing late, math errors, incorrect personal info (like Social Security numbers), forgetting deductions/credits (like EITC), misreporting income, not signing forms, and making errors with bank details for direct deposit, all leading to delays, penalties, or missed savings, with using tax software or professionals helping avoid these common pitfalls.
You can generally file back taxes to claim a refund within three years of your original return's filing date or two years of paying the tax, whichever is later; however, for unreported income (especially significant amounts or foreign income) or failure to file, the IRS can often go back six years or even longer, requiring you to file all missing returns to avoid penalties and interest, with deadlines extended for specific exceptions like bankruptcy or large omissions.
Even so, the IRS can go back more than six years in certain instances. Unfortunately, there is a limit on how far back you can file a tax return to claim tax refunds and tax credits. This IRS only allows you to claim refunds and tax credits within three years of the tax return's original due date.
You can't get a credit or refund if you don't file the claim within 3 years of filing your original return, or 2 years after paying the tax, whichever is later, unless you meet an exception that allows you more time to file a claim.
Yes, you can e-file back taxes, but typically only for the current year and the two prior years, using specialized software or a tax professional; returns older than that or filed through most self-prep sites usually need to be printed and mailed, though some software offers e-filing for older years if you have an IP PIN. You must use the correct year's Form 1040 (e.g., a 2024 Form 1040 for the 2024 tax year).
As of December 26, 2023 the IRS will no longer accept electronically filed returns for years 2020 and older. When paper filing an older tax year, such as 2020, write at the top of the return, “the IRS no longer accepts electronic filing of the tax year 2020 returns after December 26, 2023”.

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. It's always better to file a late tax return (even if you can't pay immediately) to avoid penalties, especially if you're owed a refund, which you can lose if you file more than three years late.
The IRS one-time forgiveness program, or first-time penalty abatement, is a good option if you received an IRS penalty and have a solid history of filing and paying taxes on time.
You can typically e-file your current tax return and the two prior years through the IRS Modernized e-File (MeF) system; for example, during the 2025 filing season, you can e-file 2025, 2024, and 2023 returns, but returns older than that must generally be paper-filed, though some professional software might extend this window slightly for specific forms. There are also annual IRS e-filing shutdown periods (blackout dates) when e-filing is unavailable.
