Delaware Corporation Doing Business in California: Qualification and Tax Basics

Written byPatrick Moumiet

A Delaware charter does not exempt you from California if you operate there. Here is what FTB says and what to check.

Key takeaways:

  • FTB says foreign corporations that qualify in California, or do business there without qualifying, are subject to the franchise tax.
  • The $800 minimum applies to corporations incorporated, registered, or doing business in California.
  • Newly incorporated or qualified corporations have had a first-year exception since January 1, 2020.
  • Track both states’ deadlines and ask a professional about what counts as doing business.

Qualifying versus not qualifying in California

1. The short version

A company formed in Delaware but run from California is a foreign corporation in California’s eyes. According to FTB, a foreign corporation that qualifies with the California Secretary of State becomes subject to the franchise tax, and so does one that “does not qualify with the SOS, but does business in California.”

Start with the comparison in incorporating in California vs. Delaware.

2. Qualifying vs. not qualifying

If you qualify, you file the forms; if you do not qualify but do business in California, tax can still apply; plan for the $800 minimum and ask a professional

Skipping the qualification paperwork does not make the tax go away if you do business in the state. It only means the registration side is missing too. Do not read this as legal advice on whether your activity counts as doing business; that is a fact question for a professional.

3. The usual steps

Qualifying in California: get a good standing certificate from the home state, prepare the statement and designation, file with the California Secretary of State, then calendar yearly obligations

The general sequence is to get proof of good standing from the home state, prepare California’s registration paperwork, file it with the Secretary of State, and then calendar your recurring obligations. Check the Secretary of State’s current forms and fees before you file, since they depend on entity type.

4. What it costs each year

FTB states the $800 minimum franchise tax applies to corporations incorporated, registered, or doing business in California, with a first-year exception for newly incorporated or qualified corporations since January 1, 2020. You may also owe Delaware’s franchise tax; see Delaware franchise tax for startups.

5. Seven checks
