Filing taxes in Delaware 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. Delaware is the top choice for startups raising capital, with the most developed business-court system and a flat $300 LLC franchise tax. 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 Delaware state tax filing

Delaware has a state personal income tax (2.2%–6.6%), so you'll typically file a Delaware 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.

Sales tax and nexus in Delaware

If you sell goods, Delaware's base sales-tax rate is effectively zero at the state level, though local rules may still apply, and you may have a collection obligation if you cross a nexus threshold, in-state or in other states you ship to or store inventory in. Check yours with our sales-tax nexus checker. We register you where you actually owe and fold filing into your bookkeeping.

Why file with a CPA & EA in Delaware?

"Tax preparer" isn't a protected title. A licensed CPA or Enrolled Agent can not only prepare your Delaware 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.
