Chile Will Make You Get a Tax Number Before You Can Get a Debit Card; Britain Will Make You Prove You Live Somewhere Before It Believes You Exist

🇨🇱 Chile 🇬🇧 United Kingdom By Suki Nakamura, Out of Office

In Chile, you cannot meaningfully participate in the economy — open a bank account, sign a lease, get paid properly — without a RUT, a national tax identification number that functions as the master key to adult life, and getting one as a foreigner involves a pilgrimage to the Servicio de Impuestos Internos with a folder of documents you were not warned you'd need. In Britain, you cannot open a bank account without proof of address, and you cannot get proof of address without, functionally, already having a bank account, a circular bureaucratic trap so infamous that entire expat forums exist solely to trade workarounds for it.

Both countries have built financial systems that assume you already have the thing you're trying to obtain. It's bureaucracy as a Zen koan. Let's unpack the absurdity.

Do's & Don'ts: Chile

Do's & Don'ts: United Kingdom

Chile: The RUT Is the Rosetta Stone

Nothing in Chile happens without a RUT — Rol Único Tributario — the tax identification number that functions less like a tax number and more like a passport to modern life. Want a bank account? RUT. Want to sign a rental lease? RUT. Want a phone contract, a gym membership, or to be paid legally by an employer? RUT, RUT, RUT. For citizens, it's assigned at birth. For foreigners, obtaining one means a trip to the Servicio de Impuestos Internos armed with your passport, your visa or residency documentation, and often a notarized address confirmation you didn't know you needed until the clerk asked for it, at which point you get sent away to obtain it and told, politely, to come back.

Once you clear that hurdle, Chilean banking itself is reasonably navigable — BancoEstado's Cuenta RUT is a genuinely useful entry-level account many expats use as their first foothold, requiring less red tape than a full current account. But the broader Chilean bureaucratic culture still runs heavily on physical paper and in-person processes; digital banking has improved dramatically, but core account-opening steps, document notarizations, and certain tax matters still require you to show up, in person, with a folder, and wait your turn at a ventanilla the way generations of Chileans have before you. English-language support thins out fast once you leave Santiago's business districts, so patience and at least survival Spanish are not optional extras, they're the actual toolkit.

The upside, once you're through the gate, is a banking system that's stable, modernizing steadily, and considerably less circular than its British counterpart — Chile doesn't ask you to prove you bank before it lets you bank.

United Kingdom: The Address Paradox

Britain's system contains a genuinely absurd catch-22 that has become a rite of passage for every newcomer: to open a traditional bank account, you typically need proof of address — a utility bill, council tax statement, or similar official document in your name. But to get most utilities put in your name, or a tenancy agreement processed, landlords and providers often want to see... a UK bank account. New arrivals spend weeks caught in this loop, phoning banks who want a utility bill, phoning utility companies who want a bank account, and slowly losing their minds.

The workaround, well known in every UK expat forum, is the rise of digital-first challenger banks — Monzo, Starling, Revolut — which will open an account with considerably less friction, sometimes just a passport and a UK mobile number, precisely because they built their onboarding without the assumption that you'd already cracked the address paradox elsewhere. Many newcomers now use one of these as a bridge account, building enough of a financial footprint — a few months of transaction history, an address slowly established through employer or university letters — before a traditional high-street bank will even consider them.

Beyond banking, British bureaucracy runs on an obsession with paper trail and institutional footprint: registering with a GP, getting on the electoral roll, receiving official post addressed to you at your current address — all of it slowly builds the invisible dossier that eventually convinces institutions you're real. It's not fast. A traditional account can take two to six weeks to fully activate even once accepted, and heaven help you if you move flats twice in your first year, because you'll be proving your existence all over again each time.

The Verdict

Chile's bureaucracy is intense but linear — get the RUT, and doors open in a predictable sequence. Britain's bureaucracy is a circle with no clear entry point, solved mostly by clever fintech startups filling a gap the traditional banks never bothered to close. I'd rather face Chile's one hard gate than Britain's maddening loop — at least the SII tells you exactly what document is missing. British banks, historically, just say no and let you figure out why.

What Nobody Warned You About

Reddit r/chile — a newcomer describes being sent away from the SII three separate times for three separate missing documents, none of which were on the original checklist.

Quora — a UK-based commenter explains they solved the address paradox entirely through a Monzo account and a university enrolment letter, in that order.

expat.com — a Santiago-based expat notes that having a Chilean friend co-sign or vouch at the bank branch dramatically speeds up account approval.

Conclusion

Chile and Britain both make you earn your financial existence, just via different obstacle courses. Chile demands one specific, well-defined document — the RUT — and then largely leaves you alone. Britain demands a circular proof of belonging that only resolves once a fintech app quietly does what the high-street banks refused to. Arrive prepared for either, and bring patience, photocopies, and, in Britain's case, a genuine willingness to trust an app with a cartoon logo over a three-hundred-year-old institution.
