My HHNK and Accessibility: Taxes on September 28

On Monday, September 28, major maintenance will be performed on the billing system. As a result, you will be temporarily unable to access My HHNK that day. 

Since the tax system is also unavailable to HHNK employees, we may not be able to assist you by phone as well as you are accustomed to. Therefore, please ask your questions on another day or fill out the contact form at .  

Starting Tuesday, September 29, we will once again be available by phone to answer all your questions, and you will also be able to use My HHNK again.
