The working behind Delaware

Filing work in the price put Mainstay Filing first. That term is 27% of the formula, and calculated three-year cost, renewal change, break-even year and input clarity make up the remainder.

DE Registered Agent.org calculates lower over three years, but you would file the Annual LLC Tax yourself.

Count the EIN application and DE Registered Agent.org calculates lower from year 2.

How Delaware describes its LLC filing fee and filing requirements

$110 and the Certificate of Formation of a Limited Liability Company, delivered to the Delaware Secretary of State, create the LLC. Every LLC must name a registered agent with an in-state street address.

Without a service

File alone and Delaware still bills $910 over three years, with every form on your desk. A service charging $397 to $597 removes that work.
