Common questions

Frequently asked questions.

LLC suits most freelancers, side hustles, and small operating businesses - flow-through taxation and minimal formality. S-Corp works when net profit exceeds roughly $80K and you can take a reasonable salary plus distributions to reduce self-employment tax. C-Corp is the right answer if you plan to raise from US VCs, issue stock options, or operate cross-border with a UK parent. We assess the right structure as part of formation, not after.

Delaware for C-Corps raising venture capital (predictable corporate law, Court of Chancery, what investors expect). Wyoming for single-member LLCs prioritising privacy and low fees. Your home state for most operating businesses where you actually have employees, customers, or premises - registering out-of-state adds a foreign qualification fee in the home state and no real benefit.

State filing fee for your chosen state, Certificate of Incorporation, EIN registration with the IRS, customised Operating Agreement (LLC) or Corporate Bylaws (Corp), organisational resolutions, registered agent for the first year, and a US mailing address. Expedited filing in all 50 states is included as standard - most certificates come back within days, not weeks.

Yes - the US has no residency or citizenship requirement for owners or directors of LLCs and C-Corps. You will need an EIN (we obtain it for you via Form SS-4, which takes 4-6 weeks for non-residents without an SSN) and a US registered agent and mailing address (both included). US bank accounts can be opened remotely through Mercury, Relay, or Wise Business once the EIN is issued.

Annual report and franchise tax filing in your state of formation (varies by state - Delaware C-Corps from $225, Wyoming LLCs from $60), federal tax return (1120, 1120-S, or 1065 depending on entity type), state tax returns where applicable, and BOI reporting under the Corporate Transparency Act for most small entities. We send reminders and handle filings as part of our ongoing US compliance package.
