FAQ

What is geo-arbitrage and why does it accelerate FIRE for IT freelancers?

Geo-arbitrage means earning income at one country's rates while living in a country with lower costs and, often, more favourable tax treatment. For software developers it can mean billing US or Western European clients while basing themselves in Portugal, Spain, or other lower-cost regions. The combination of higher revenue and lower expenses can lift savings rates above 60%, dramatically shortening the timeline to financial independence.

How long does it take to reach FIRE as an IT freelancer using geo-arbitrage?

Realistic timelines depend on income and savings rate, but aggressive paths often land in the 8–12 year range for high-earning freelancers with savings rates above 60%. Mid-range earners typically need 12–18 years, while early-career freelancers should plan for 15–25 years. Specialisation, premium pricing, and disciplined automation are the strongest accelerators.

What tax considerations matter most when relocating as a freelancer?

Tax residency rules, double-taxation treaties, social contribution obligations, and any special programs offered to incoming professionals are the four pillars to research before moving. Mistakes here can be expensive, so most freelancers consult a qualified cross-border tax advisor before changing residence. Treat the move as a structured project: plan invoicing, currency flows, and reporting before the relocation, not after.

How should an IT freelancer handle multiple currencies for income and investing?

A multi-currency business account keeps FX fees low and lets you hold revenue in the currency it was earned. Many freelancers convert on a fixed schedule rather than reacting to short-term rates, which reduces stress and prevents timing mistakes. For investing, choose ETFs that match your long-term spending currency to avoid layering unnecessary currency risk on top of market risk.

What's the best way to diversify client risk as a freelancer pursuing FIRE?

Cap any single client at roughly 30–50% of total revenue and spread the rest across industries, company sizes, and geographies. Combine project work with retainers, plus a small slice of recurring or passive income such as courses, templates, or SaaS. This mix protects your savings rate when one client churns or an industry slows down.
