Massachusetts State Taxes

CINTAX does not provide assistance with state tax returns. The HIO has hired noted tax attorney Paula Singer to create a web site for us that would address the issues not covered by CINTAX. These include Massachusetts state returns for residents and non-residents, as well as federal resident returns and dual status returns. The site includes sample tax returns but does not complete the forms for individuals. It is available to anyone with a valid Harvard ID and PIN. Users will need their HUID and PIN to access the site.

You may also go to the Massachusetts Department of Revenue websites listed below for forms and information.
