10 Costly Mistakes Expats in Europe Make in Their First Year — And How to Avoid Them in 2025
Last month, Sarah from Toronto lost €2,400 in her first six months in Lyon. Not to scams or bad decisions — but to administrative mistakes she didn't even know she was making. She's not alone. In 2025, the average expat loses between €1,800 and €4,200 in their first year through delayed registrations, missed deadlines, overpayments, and rejected applications. The worst part? These mistakes are 100% avoidable — but only if you know what to watch for. European administrative systems are designed for locals, not newcomers. They're fragmented, unforgiving, and full of invisible traps that cost you time, money, and peace of mind. This guide reveals the ten most expensive first-year mistakes expats make in Europe in 2025 — and gives you the exact step-by-step solutions to avoid every single one.
