Frequently asked questions

Can a non-US resident form a Delaware LLC?

Yes. Non-US residents can form a Delaware LLC without a Social Security Number, US address, or US presence. You need a passport for identity verification, an EIN for IRS purposes, and a Delaware Registered Agent. Delewarellc forms Delaware LLCs for non-resident founders for $297 plus the $110 Delaware state fee.

What does a Delaware LLC cost?

Delaware LLC year-one costs are $110 state filing fee plus registered agent fees ($50-$179/year depending on provider) plus optional service fees. Delewarellc charges $297 plus the state fee for full formation including registered agent for Year 1, EIN application, Operating Agreement, and bank account applications.

Do I need a US address to form a Delaware LLC?

No. You do not need a personal US address. The Delaware LLC needs a registered agent address (which Delewarellc provides) and an address for IRS correspondence (which can be your home address abroad).
