The state's side of the math, Delaware

Term Value Where it comes from
Formation charge $110 delcode.delaware.gov (checked October 2026) as the source
Annual LLC Tax $400 every year legis.delaware.gov (checked October 2026) as the source
Cost of missing the deadline $200 legis.delaware.gov (checked October 2026) as the source
State side, 3 years $910 Filing + reports + any tax

Our state figure adds three things: the filing, two years of reports and a minimum tax where there is one. Variable costs like publication stay out.

Why row one is row one

Mainstay Filing scored above DE Registered Agent.org on items covered per dollar, a 28% term.

Delaware wants the Annual LLC Tax every year, so a price that files it scored above a lower price that does not.

Include the EIN application in the math and Mainstay Filing passes DE Registered Agent.org in year 2.

Delaware LLC filing fee and rules, from the source

The LLC exists once the Delaware Secretary of State accepts the Certificate of Formation of a Limited Liability Company along with $110. Every LLC must name a registered agent with an in-state street address.
