Message from Secretary Casey

​​​​​​​​​​​​​​​​Secretary David CaseyWe know January is a whirlwind month for business owners, and we're here to help you get ahead of the rush. To keep things stress-free, we encourage you to log into My Tax Account (MTA) early to beat the February 2 deadline. Just a friendly reminder: even if you didn't have sales this period, you'll still need to file a "0" return if you had an active account in 2025. Check out our video series​ for more information on how to file.​
