When to File Previous Year or Late Federal Tax Returns

There is no IRS deadline for overdue previous year tax returns, but in order to claim a tax refund for a certain year, you must file a tax return for that year within 3 years of the original due date. If you wait longer than 3 years, any tax refund is forfeit.

On the other hand, past due taxes do not disappear. If you owe taxes for a previous tax year, the IRS may charge you late filing and late payment penalties plus interest on taxes owed.

After April 15, 2019, you can still prepare and efile a 2018 Tax Return on until October 15, 2019 (after that date, the IRS will no longer accept 2018 returns electronically, and you will need to paper file your 2018 return).

If you owe taxes and you file or efile late without getting a tax extension, the IRS will generally charge penalties based on the amount you owe. There are also penalties for paying your taxes late, even if you got an extension. However, the late filing penalties are more severe, so you should try to file on time even if you owe taxes and can't pay.

If you owe taxes and are already late, you should file a tax return immediately and explore your options to pay tax.

If you expect a tax refund and you file late, there is no real penalty other than the effective delay of your refund.

When to File an Amended Tax Return (Tax Amendment)

If an amended return results in you owing tax, there is no deadline for the tax amendment. However, if you're expecting a refund, you must file your return within 3 years of the original tax return deadline in order to claim your refund.

Tax Tip: Submit your 2018 Tax Return by April 15, 2019 to avoid penalties and interest!
