Business Taxes

Businesses come in all sizes — from large multinational corporations to sole proprietorships. The pages in this section have the information you need to fulfill your business tax obligations to the Commonwealth.

There’s more to business taxes than registering, filing, and paying with MassTaxConnect. Although this page will help you to do that, we’ll also point you toward other helpful information. You can learn how to apply for an Employee Identification Number (EIN), request a motor vehicle sales or use tax abatement, or learn more about business tax credits. From verifying a sales and use tax resale certificate to finding the latest information on corporate excise tax, we look forward to working with you.
