"Our new Montana Adoption Credit form will be available and your software provider will have it for the 2023 filing season. You can tell your 2022 credit-eligible clients that they can apply for the credit on their 2023 Montana state income tax return. Any adoption finalized between July 1, 2022 and December 31, 2023 will potentially be eligible for the credit in 2023. Taxpayers will need to provide (along with the adoption credit form) court documents or other proof of the adoption; or, in the cases of foster care adoptions, a certification letter from our Department of Health and Human Services.

We will have an updated webpage with this information by the end of the month. Thanks for your patience and have a good weekend."
