When Spain wins over a US LLC
- EU member
- LATAM connection
- You sell to customers in Europe and benefit from local market presence.
- UBO register is non-public — stronger privacy than US BOI requirement (which is at least internally accessible).
When a US LLC wins over Spain
- Banking: Mercury, Brex, and every US bank accept non-residents. Spain banking is 8/10.
- Stripe and payment rails: US has the most mature payment ecosystem in the world.
- Pass-through taxation: a US LLC owes 0% federal corporate tax on retained or distributed profits. Tax obligation falls on the owner personally — and if the owner is a non-resident with no US-source ECI, that's also often 0%.
- Filing cost: $162 year-1 in Wyoming vs $250 in Spain.
- Speed: Wyoming LLC in 1-2 days vs 10 days in Spain.
The hybrid approach many founders use
Many non-US founders form both entities:
- A US LLC (usually Wyoming) for Stripe, US customers, and US-facing brand.
- A local Spain entity for substance, local employment, and local market.
The US LLC bills the Spain entity or vice versa, with transfer-pricing documentation. This is common in SaaS and digital agencies. Talk to a cross-border CPA before structuring.
Decision matrix
- Selling globally / mostly US? → US LLC.
- Selling in Europe / locally? → Spain entity.
- Need both Stripe and EU/local presence? → Hybrid.
- VC fundraising plans? → Delaware C-Corp (not LLC, not Spain).
