Penalty Truth: After three years, you can no longer claim a tax refund for that year (but you may still file a tax return). However, if you owe taxes, you’ll need to file your return as soon as possible as well as owe back taxes and penalties (late filing penalties for each month your return is not filed).

There is usually no penalty for failure to file, if you are due a refund. But, if you wait too long to file a return or otherwise claim a refund, you risk losing your refund altogether. In most cases, an original return claiming a refund must be filed within three years of its due date for the IRS to issue a refund.

What happens if I don’t file my taxes by April 15?

If the government owes you, you’ll lose your refund if you don’t file within 3 years of the April tax filing deadline date. This means that for tax year 2019 returns, you’ll need to file by April 15, 2023 to claim your refund (October 15, 2023 if you filed an extension).

What happens if you file taxes 3 years overdue?

Bad news: for any year more than three years overdue, you cannot file a tax return and claim the refund. Still have questions? Visit an H&R Block office near you for help catching up on back tax returns.

What happens if I don’t file my 2020 taxes?

If the government owes you, you’ll lose your refund if you don’t file within 3 years of the tax filing deadline date. This means that for tax year 2020 returns, you’ll need to file by May 17, 2024 to claim your refund (October 15, 2024 if you filed an extension).

What happens if you haven’t filed your taxes for 2012?

However, if you have not yet filed a return for 2012, 2013 or 2014, you can still file and receive any refund due. You will need to file the returns on paper, which means the processing takes a little longer, but you can get that refund and not pay any penalties.
