Filing taxes in Connecticut means getting both your federal return and your state obligations right, prepared and signed by a licensed professional who can represent you if the IRS or the state Department of Revenue ever has questions. Connecticut charges an $80 annual report fee for LLCs. Whether you are a resident, an expat filing from abroad, or a business owner facing an IRS notice or audit, here's what filers in the state need to know.

Federal and Connecticut state tax filing

Connecticut has a state personal income tax (2%–6.99%), so you'll typically file a Connecticut state return alongside your federal one. Whether you're an individual, a freelancer, an LLC, an S-corp, a C-corp or a foreign-owned business, the return has to reconcile income, deductions and credits correctly, and be filed by the deadline to avoid penalties and interest. We prepare and e-file both layers, and a second licensed professional reviews every line before anything is signed.

Why file with a CPA & EA in Connecticut?

"Tax preparer" isn't a protected title. A licensed CPA or Enrolled Agent can not only prepare your Connecticut and federal returns but also represent you before the IRS if a notice arrives, something a PTIN-only preparer can't fully do. Our tax filing service covers both, year-round, at a flat fee, so the person who files your return in April is the same one who answers the IRS in September.
