What to know before you go
Carnival is not optional background — plan your February around it
CriticalKarneval peaks in the week before Lent, and Weiberfastnacht and Rosenmontag effectively close the city: offices shut or empty, public transport reroutes, and the streets fill from morning. It is genuinely joyful and genuinely inescapable. Do not schedule anything important, do not expect shops or offices to behave normally, and if you have no interest in it, plan to be elsewhere — half the city does exactly that.
Register within two weeks, and Cologne's appointments are easier than Munich's
CriticalThe Anmeldung must be done at a Bürgeramt within two weeks of moving in, gating your tax ID, bank account, health insurance and residence permit. Cologne's availability is considerably better than Munich's, but the deadline is real and everything downstream waits on it. Book online as soon as you know your move date.
Church tax in North Rhine-Westphalia is 9%
CriticalDeclaring membership of a recognised church at your Anmeldung triggers automatic deduction of church tax at 9% of your income tax liability in NRW — as in most German states, against 8% in Bavaria and Baden-Württemberg. Declaring no affiliation means no church tax. The question is asked in a short appointment most newcomers do not realise carries an annual cost.
Health insurance is compulsory and the choice is near-irreversible
CriticalEveryone in Germany must hold health insurance. Employees below an income threshold join the statutory system; above it, private becomes available. Private is often cheaper when young and healthy, considerably more expensive later, prices each family member separately, and is very difficult to leave. Statutory covers dependants free. Decide on the thirty-year view.
This is the cheapest and most relaxed of Germany's big cities
ImportantCologne's rents sit well below Munich's and Frankfurt's, and the city has a reputation — earned — for being socially open, informal and easy to make friends in. It has one of Germany's largest queer communities and a genuinely welcoming temperament that the Kölsches Grundgesetz half-jokingly codifies. For a newcomer worried about German reserve, this is the softest landing of the big five.
You are in the middle of a dense rail corridor
ImportantCologne sits on the Rheinschiene: Bonn is 20 minutes away, Düsseldorf 25, and the Ruhr cities beyond that, all on regional rail covered by the Deutschlandticket. Living in one and working in another is entirely normal. It also means Brussels, Amsterdam and Paris are all direct high-speed trains, which materially changes what a weekend can be.
