Your Kansas filing status must be the same as your federal filing status. If your federal filing status is ‘Qualifying Widow(er) with Dependent Child,’ select ‘Head of Household’. If you and your spouse file a joint federal return, you must file a joint Kansas return, even if one of you is a nonresident. If you and your spouse file separate federal income tax returns, you must file separate Kansas returns.

Select YES to amend your 2023 return. For previous years, complete the appropriate Form K-40 from the Kansas Department of Revenue for the year you are amending.

• 2022 Form K-40
• 2021 Form K-40
• 2020 Form K-40
• 2019 Form K-40

Amended returns must be filed within three years of when the original return was filed. If the amended return will result in a refund to you, it may be filed within three years from the original filing, or within two years from when the tax was paid. You must file an amended Kansas return if:

• An error was made on your Kansas return; (OR)
  
• There is a change on another state's return (error or adjustment); (OR)
  
• There is a change on your federal return (error or adjustment)

If you are filing an amended return, you cannot change the filing status from 'joint' to 'separate' after the due date has passed for filing a separate return. If you did not file a Kansas return when you filed your original federal return, and the federal return has since been amended or adjusted, use the information on the amended or adjusted federal return to complete your Kansas return.

If a previous return was not correct, or if your original return was adjusted by the IRS an amended return MUST be submitted within 180 days of the date the federal adjustments are paid/agreed to/become final (whichever is earlier). Failure to properly notify the Director of Taxation within the 180-day period will cause the statute of limitation to remain open (The Kansas Department of Revenue could make assessments for as many years back as necessary.)

If you know that a previously filed return was not correct, or if your original return was adjusted by the IRS, an amended return MUST be submitted within 180 days of the date the federal adjustments are paid/agreed to/become final (whichever is earlier). Failure to properly notify the Director of Taxation within the 180-day period will cause the statute of limitation to remain open (The Kansas Department of Revenue could make assessments for as many years back as necessary.)

Check 'Yes' if someone other than the taxpayer is completing this return. This includes professional tax preparers, family members, friends, etc. Later in the return you will have the opportunity to enter more information about the tax preparer.
