Buenos Aires grand boulevard at golden hour

Moving to Argentina
from the UK

Practical guides on visas, HMRC, NHS, banking, schools and the unglamorous end of Buenos Aires life. Written by someone who spent six weeks unpicking it for his sister.

My sister asked me, over a drink, whether she should move her family to Buenos Aires. Six weeks of research later, I wrote her a folder of notes. This is the folder.

Argentina is one of the odder moves a British person can make. Far enough to feel properly foreign, cheap enough to reset your finances entirely, and bureaucratic in ways Google Translate will not help you with. Most of the guides you find online split into two camps: travel pieces about a long weekend in Palermo, or forum threads about someone's Migraciones appointment going sideways at 9am on a Tuesday. Neither is much use if you are actually planning to live there.

My sister wanted to sell her flat in Lewisham and move her husband and two children to Buenos Aires for three years. The answer turned out to be yes, but it took me six weeks of reading into apostilles, HMRC form P85, frozen state pensions, the dólar MEP, Palermo rents in ARS at the parallel rate, British-curriculum schools in Olivos, prepaga tiers, and whether the UK triple lock survives if you give up UK tax residency. None of it was in one place. After three more friends asked me the same thing, I stopped emailing the folder and put it here.

I'm not a lawyer or an accountant — I spent a decade covering personal finance for national UK publications, which means I know how to read a primary source and spot when something has changed. Every guide starts with the actual gov.uk page, the actual HMRC manual, the actual Migraciones decree, and every guide is dated with the last time I checked it. When the answer genuinely needs a chartered accountant with international experience or a qualified immigration lawyer, I say so — and I point you at the kind of professional you should actually talk to, rather than pretending a spreadsheet is going to do the job.

The ones most people read first

Broadly, readers split into two camps. The ones who are still weighing it up want the visa overview, the money piece, and the cost-of-living comparison. The ones who already have a flight booked skip ahead to the apostille, the school-picking and the first-week checklist. Both groups tend to read the pensions guide eventually and look mildly alarmed.

Work it out on a screen before you work it out on a plane

Three small interactive things that save a fair bit of reading. Rough numbers only — they won't replace a proper accountant, but they will tell you whether the idea is roughly solvent before you start queuing at the FCDO.

Nobody told me about the Statutory Residence Test until I'd already filed my first Argentine tax return. Would have saved me about two grand in accountant fees if I'd read the HMRC guide first.

Palermo

Moved from Leeds with two kids and quietly terrified about all of it. The paperwork checker stopped me apostilling the wrong documents twice. The schools guide pointed us at St Andrew's. Sorted.

Belgrano

Came out here on the pension. Rent is a third of what I paid in Bristol. My only complaint is the Wi-Fi, and even that's getting better.

The ones I get asked most often

A few short answers. Each links through to a proper guide if you want the working-out.

Do UK citizens need a visa for Argentina?

British passport holders enter Argentina visa-free for 90 days. You can extend once for another 90 days at Migraciones. For longer stays, apply for residency — the Digital Nomad Visa, Rentista, or Temporary Residency depending on your circumstances.

How much does it cost to live in Buenos Aires vs the UK?

Day-to-day costs in Buenos Aires run 50–70% cheaper than the UK. A two-bedroom flat in Palermo costs £300–500/month (vs £1,400–2,200 in London). Dining out is 70–80% cheaper. Private healthcare runs £80–150/month for top-tier coverage.

What happens to my NHS entitlement?

Moving to Argentina means you leave the NHS system. You can return and re-register with a GP if you move back. While in Argentina, private healthcare (prepaga) is excellent and affordable — OSDE, Swiss Medical, and Galeno are the main providers at £80–150/month.

Do I need to tell HMRC I'm leaving?

Yes — complete form P85 (Leaving the UK) and understand the Statutory Residence Test for your UK tax status. The UK-Argentina double taxation agreement exists but is complex. Get professional advice from an accountant who knows both systems.

Is my UK State Pension frozen in Argentina?

Yes — Argentina is a frozen pension country. Your UK State Pension stays at whatever rate it was when you left, with no annual increases. This matters enormously for retirees planning long-term. You can still receive it, but the amount won't go up. See our pensions guide for the full picture and workarounds.

How do I apostille UK documents for Argentina?

UK documents need an apostille stamp from the FCDO Legalisation Office (£30–45 per document, 2–4 weeks). Common documents: birth certificate, police check (ACRO), degree certificates. The apostille confirms the document is genuine for use in Argentina.

When the answer really depends on your case

These guides cover the general shape of things. For the decisions where your personal paperwork decides the answer — residency categories, tax residence, inheritance — you want a qualified immigration lawyer who can look at your file.
