Business Taxes

Businesses come in all sizes — from large multinational corporations to sole proprietorships. This page has the information you need to fulfill your business tax obligations to the Commonwealth.

Learn how to register your business with MassTaxConnect — DOR's web-based application for filing and paying taxes. You can also learn how to apply for an Employee Identification Number (EIN), request a certificate of good standing, or find out about the latest business tax credits.

From verifying a sales and use tax resale certificate to finding the latest information on corporate excise and withholding tax — we look forward to working with you.
