Tips and Help
  • Free Assistance through The Piton Foundation. Find a site near you.
  • Save time and file online! You may use the Department's free e-file service Revenue Online to file your state income tax. You do not need a Login ID to File a Return. After you file, you have the option of setting up a Login ID and Password to view your income tax account in Revenue Online. Or, you may opt to e-file through a paid tax professional or purchase tax software to complete and file returns. NOTE: If you are a first-time filer, you cannot use Revenue Online. You must either submit a paper return or use a third-party software to file electronically. You may use Revenue Online after you’ve filed your first tax return with the Department.
