Can non-US residents use Firstbase to form a company?

Firstbase works for non-US residents, and you do not need to be a US citizen or resident to form a US company through it. It explicitly supports a single-member LLC owned by a non-US person, and it handles the two things that normally trip up international founders: obtaining a US EIN and setting up a US business bank account (with Mercury).

That combination (EIN plus banking, arranged remotely) is what makes forming and actually operating a US company realistic from abroad. Without an EIN you cannot open a bank account or file taxes, and without a bankable US presence the company cannot transact, so bundling both into the setup removes the real obstacles.

What forming a US company does not do by itself is settle your tax obligations, and this is where non-resident founders must be careful: a foreign-owned US LLC has specific US filing requirements, and Firstbase offers tax filing to handle them, but the obligation exists regardless of which service you use. Forming is straightforward; staying compliant is the part to plan for.

This is general information, not tax or legal advice. Your obligations depend on your country, residency, and business activity, so confirm your specific situation with a qualified professional.
