What should expats financially organize in the first 30 days in Germany?

Germany runs on paperwork, and your first month sets the rhythm for everything that follows. The single most important step is the Anmeldung — registering your residential address at the Bürgeramt, which usually has to happen within two weeks of moving in. It triggers your Steuer-ID (tax identification number), which arrives by post a few weeks later. Without these, your employer can't put you on payroll properly and most banks won't fully open an account for you.

Once the Anmeldung is done, the rest follows in a fairly natural order: open a German bank account (your IBAN is what your employer needs for salary and what landlords expect for rent), make sure your health insurance is active from your first day of work (your employer usually handles the initial registration if you're going public), and double-check your employment contract for any tax-class details that affect your monthly net pay.

One small step that's easy to forget but really worth doing early: take out personal liability insurance (Privathaftpflichtversicherung). It's cheap — usually around €5 per month — and in Germany you can be held personally liable, without limit, for accidental damage you cause to others. It's the kind of thing you set up once and never have to think about again.

Anything beyond this — investments, retirement, additional insurances — can wait until your basics are stable. The first month is just about laying solid foundations.
