Business and Occupation (B&O) tax return

Sidr Tax will also file your Business and Occupation (B&O) tax return as part of the Autofile process for free. We assume that your business classification is Retail. If that is not the case, please let us know ahead of time.

Please note that the B&O tax is not visible in our tax reports, since the B&O tax is similar to the Corporate Income Tax and not collected from your customers.
