Department of Revenue update on tax law changes for tax years 2017, 2018, and 2019

The department is reviewing the tax law changes that were signed into law in late May and their impact on our customers. We are working with tax software providers to ensure they have the resources and information necessary to update their systems to reflect the tax law changes for all affected tax years.

For tax years 2017 and 2018

You do not need to take any action at this time. Do not file or amend any returns relating to retroactive provisions for 2017 and 2018 in this year's legislation. 

• In early July we plan to post updated near final 2017 and 2018 individual and business tax forms for review. 
• In late August/early September software vendors will have updated software available for use in filing. The department will publish a list of vendors who have updated their filing software.

For tax year 2019

We will follow our usual timeframes for publication of forms, vendor certification and testing, and opening filing season. View the timeline for 2019.

We will also provide further guidance, resources, and answers to FAQs we’ve received as they become available on our website and through these Tax Law Change email updates.
