However, IRS officials deny that filing an amended return increases your audit chances. Amending your return will likely not result in an audit unless there is a substantial change in your taxable income without a reasonable cause.

How often are amended tax returns audited?

In most cases, the IRS is limited to the same three-year period you have for amending your taxes to audit the original return, but once you amend it, the agency gets an additional three years to audit the amended return.

Is it worth filing an amended tax return?

You don't need to file an amended return if you discover a simple math or clerical error on your return. The IRS can correct those types of mistakes on its own. An amended return isn't necessary if you forgot to attach a certain form or schedule to your return, either.
