Kansas residents who qualify for Other State Tax Credit (which includes KCMO earnings tax) are required to attach copies of the returns for which they are claiming a credit. For tax year 2023, KCMO returns must be efiled. However, if the correct 1% earnings tax is withheld by the employer, no return is required. In prior years, the return was completed, even if not needed for filing, to attach to the Kansas return, to maximize the Other State Tax Credit. In 2023, you can prepare the KCMO Form 108 within ProSeries, but it cannot be printed to attach to the Kansas return. Neither can the return be prepared online since no return is required. What are others doing to resolve this & allow taxpayers to get their full credit owed?
