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 both residents and non-residents, as well as federal resident returns and dual status returns. This site includes sample tax returns but does not complete the forms for you. It is available to anyone with a valid Harvard ID and PIN. Users will need their HUID and PIN to access the site [HERE]

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