Planning for taxes

Filing tax returns

Once you have registered your business you will receive a letter from the Department of Revenue with your UBI/account ID number and filing frequency.

You must file and pay excise taxes electronically. For more information, visit our mandatory e-file page.

Businesses who have received a waiver from the mandatory e-file/e-payment requirement

If your business has received a waiver, keep in mind:

• Pre-printed returns will be mailed before the due date. 
• The due date is printed on your tax return.
• You are required to file and pay taxes by the due date even if you do not receive a tax return.
• If the due date falls on a weekend or legal holiday, the due date for the return is the next business day.
• Your nine-digit Account ID  is printed above your name and address on the tax return. Write this number on:
  • the deduction detail pages (if reporting deductions on your tax return)
  • any related forms
  • your check

The easiest way to file and pay your taxes is online using My DOR.
