Hi everyone,

I’m trying to understand whether my case is really an entity choice issue or more of a Spain/U.S. tax residency and transition timing issue.

My situation

• I live in Spain
• I have a U.S. Green Card
• I will likely remain Spanish tax resident in 2026 because I will spend more than 183 days in Spain
• My likely full move to Florida would be in 2027

My business

• Self-employed in Spain
• Consultant, mostly online
• Clients currently 100% Spanish
• Revenue around €150k–€170k
• Expenses around €20k
• In Spain, roughly 50% of profits currently go to taxes/social contributions

My question

I’m considering opening a U.S. entity before the full move and gradually moving my most important clients there.

But my concern is that if I am still fully tax resident in Spain, and the activity/management is still effectively Spain-based, then opening a U.S. LLC may not really solve the actual problem.

So I’m trying to understand whether:

• a simple LLC is just adding complexity too early,
• a S-Corp or C-Corp would make any sense before the move,
• or whether the cleanest option is simply to keep operating personally in Spain until I actually relocate in 2027, and then restructure properly

I’m not trying to avoid taxes everywhere. I’m trying to avoid a bad mismatch, bad timing, or an unnecessary structure during the transition.

Would you see this mainly as:

1. a residency / treaty / timing issue, or
2. an entity choice issue?

Thanks.
