ABOUT APEXTAX
ApexTax designs your tax, visa and employment move to Spain — then coordinates the vetted professionals who execute it. Built and led by Gerard Martínez, Founder & Cross-Border Relocation Strategist.

FOUNDER
I'm Gerard Martínez, founder of ApexTax. I've spent my career in cross-border employment — helping over 100 people from more than 15 countries work legally in Spain and build their move here.
ApexTax is where that experience becomes a service: a single strategist who designs your move and coordinates the specialists who carry it out, so you deal with one person instead of five disconnected advisors.
Get in touchTHE GAP WE FILL
On one side, generic relocation agencies that treat tax as a footnote — fine for paperwork, out of their depth on residency, Beckham or wealth structuring.
On the other, law firms: expert, but expensive, rigid, rarely English-first, and with no one coordinating the whole picture for you.
ApexTax sits deliberately between the two. Tax-first depth, an English-first experience, and a single point of contact who holds the whole plan together — from first call to fully set up.
EXPERIENCE & EXPERTISE
My background is in the global Employer of Record industry, where I've spent years helping international companies and professionals navigate cross-border employment into Spain — contracts, compliance, residency and the tax questions that come with moving.
That's the angle most relocation services miss: they handle the visa, then leave the tax and employment structure as an afterthought. I lead with it, because it's where the costly mistakes happen.
I hold the IBFD Certificate of Professional Training in Principles of International Business Taxation, awarded by the International Bureau of Fiscal Documentation (IBFD), strengthening the technical foundation behind ApexTax's strategy work.
ApexTax is a strategy and coordination consultancy — not a law firm or a licensed tax advisor. The technical filings are handled by qualified, regulated professionals we coordinate.
HOW IT WORKS
Three steps. One point of contact throughout.
Diagnostic
We map your situation — tax residency triggers, visa eligibility, employment structure and timeline — before anything is filed.
Strategy
We design your tax position, visa pathway and work setup as one coordinated plan, not three separate engagements.
Execution
The right specialists file and execute — and you deal with one point of contact throughout.
The specialists behind the work are independent, regulated professionals selected and coordinated by ApexTax: international tax advisors, immigration lawyers, gestores, EOR partners and umbrella companies, plus regulated financial and investment advisors where wealth structuring is involved.
