The honest version

Who this is, and isn't, for.

Freelancers rarely get Beckham.The regime is mainly for employees; freelancers generally can't use it. If you freelance, ask before you plan around it.
Registering as autónomo is different.Self-employed Digital Nomad Visa holders register with Social Security after approval. We guide you through the autónomo steps.
A consultation isn't a filing.Ongoing returns are a separate engagement with the firm.
Prefer to do it yourself?Xolo handles invoicing, taxes and accounting for freelancers.

Tax advice questions

How much does a consultation cost?

Premium consultations are €200–€350.

Can I use the Beckham Law?

It's mainly for employees relocating to Spain. Freelancers generally can't. GS Legal plans it with you before you arrive.

I'm a US citizen. Will I be taxed twice?

That's the firm's speciality: dual taxation and double-taxation relief between the US and Spain.

What is Form 720?

The declaration of assets held outside Spain. GS Legal prepares it, along with wealth tax filings.

Who registers me as autónomo?

Freelancers register with the tax office and Social Security after their visa is approved. On a Digital Nomad Visa with us, we guide you through the autónomo steps, and a tax advisor can file your returns. GS Legal is for planning and complex cross-border cases.

Plan your tax move before you make it.
