It is not unusual for a taxpayer to leave a deduction or credit off his original tax return, or find other reasons to amend a tax return, only to learn of it after the return is filed. If that happens, the procedure for correcting the original return is to file a Form 1040X. This form contains a summary of your original and corrected information, with an explanation of the change. The tax is computed under both scenarios and the difference, in the case of an overpayment with the original return, is refunded.

Reasons to Amend a Tax Return

If you discover that your tax return is incorrect, whether you owe the Internal Revenue Service money or it owes you money, you should file an amended return. You can amend taxes after a refund or after paying a tax bill, and the IRS will either issue you an additional refund if the government owes you money or collect your payment if you owe the government money. If you file an amended tax return and owe money, you may be required to pay interest or penalties depending on the circumstances.

If you file an amended tax return and do not include evidence for the amendment, you may increase your chances of being audited. If, for example, you forgot to deduct your real estate taxes, you should send a copy of the real estate tax bill with the amended return. The greater the amount of the refund, the more likely it is you will be audited.

The IRS normally has three years to audit a tax return, except in cases of fraud or failure to file. You also have three years in which to file an amended return. If you discover your omission of real estate taxes four years after you filed your original return (including extensions), you are out of luck. But filing an amended return does not extend the three-year statute. So if you file your original return on April 15, 2016, and your amended return on July 15, 2019, the IRS still has only until April 15, 2019 to audit you.

State Taxes and Amended Returns

If you live in a state that has an income tax, don't forget that you may need to file an amended state tax return as well to reflect the same changes that motivated you to change your federal return. You may be due an additional refund from the state as well if you're due one from the federal government.

When in doubt, consult with a tax professional or your state's tax authority.

2018 Tax Law Changes and Older Returns

As of tax year 2018, tax brackets and a number of deductions are changing, so make sure you understand the current tax situation when filing or you may be more likely to need to amend your return later on.

Generally in 2018, you can file amended returns for years going back to 2015.

2017 Tax Law and Amended Returns

If you are filing an amended return for a previous year such as 2017, remember to file according to that year's tax law, not the current year.
