Moving Back to the UK from Abroad: Argentina Checklist

If you are moving back to the UK from Argentina, first secure the right of each person to enter and live in the UK, then fix your departure and arrival dates for tax, healthcare, freight and school admissions. A British citizen can return on a valid British passport; an Argentine partner without British or Irish citizenship will usually need the appropriate UK immigration permission before travelling to settle. Start 8–12 weeks before the move if you have a home to surrender or goods to ship, and keep your Argentine bank and phone usable until the final payments clear.

The return timetable

These windows are planning targets, not government processing guarantees. A UK tax year runs 6 April to 5 April; Argentina generally uses a calendar tax year. Put both date ranges on one timeline before you give up the flat.

1. Confirm who can actually move

1. Check every passport. A British citizen should travel with a valid British passport; arrange renewal before booking if expiry or damage could prevent boarding. Keep old passports and your Argentine DNI (Documento Nacional de Identidad, national identity card) as evidence of where you lived and travelled. See renewing a British passport from Argentina if you cannot wait until you land.
2. Separate a partner's status from yours. Marriage to a British citizen does not itself grant an Argentine citizen UK residence. Check the family-visa requirements, including relationship evidence, financial requirement, English and accommodation, and apply through the correct route before the proposed move. A visitor route is not a substitute for permission to live or work. The UK visa for Argentine partners guide covers the decision in more detail. Fees and decision times depend on route, location and priority service: obtain the live amount and timescale from GOV.UK before paying for non-refundable travel.
3. Check children separately. A child born in Argentina may be British, but that depends on the parent's citizenship and how it was acquired; a UK birth certificate alone is not the only possible proof. Arrange the correct passport or entry permission for the child rather than assuming their parent's document covers them. Carry birth and custody documents, especially when one parent travels without the other.
4. If a pet is coming, start before you book flights. Great Britain's rules depend on species, country of origin, microchip, rabies vaccination and approved route. Argentina's rabies-document route must be checked against the current GOV.UK country list; dogs can also face tapeworm-treatment requirements. Get the vet and carrier to agree the timetable, certificate and flight route in writing. A pet travel document accepted for Argentina-to-UK travel is not the same thing as an airline booking.

This page assumes a return to the UK, not an Argentine tourist visit to Britain. If you will continue living in Argentina and merely visit, the UK immigration, NHS and tax position can be different.

2. Close out the Argentine household without losing evidence

1. Give notice under your own lease. After DNU 70/2023, rent currency, adjustment dates and term are negotiated rather than fixed by the old rental law. Check the actual early-exit clause and written notice channel. Book a joint inspection; record meters and the condition of each room with dated photographs. Request a signed handover and a deposit-accounting date, including expensas (building service charges).
2. Make a final-bills list. Name the landlord or agent, building administrator, electricity, gas, water, internet, mobile and any prepaga (private prepaid medical plan). Note the account holder, meter or customer number, billing cycle and cancellation reference. Do not cancel health cover ahead of your departure or any necessary care; do not assume a utility stops billing on the day you hand back keys.
3. Collect employment and tax paperwork. Obtain final payslips, proof of salary settlement, work contract termination and any Argentine tax or social-security records. ARCA (Agencia de Recaudación y Control Aduanero, Argentina's revenue agency, formerly AFIP) is the tax authority. If you registered a CUIT (tax identification number), monotributo (simplified small-business tax regime) or local self-employment activity, review formal deregistration and outstanding returns with an accountant who handles your particular registration. Simply leaving the country does not cancel filings or establish a new tax residence date.
4. Keep access to your money. Save statements, tax payment receipts, proof of the origin of savings and evidence for moving larger balances. Transfer proceeds by a regulated bank or transfer provider after comparing the amount received in sterling and fees. The September 2026 reference rate was about ARS 1,545 per US$, not a promise of the rate you will receive when you leave. Keep an Argentine payment method until the landlord's deposit, final invoices and any tax refund or liability are accounted for. Preserve the Argentine SIM or change bank two-factor settings before disconnecting it.
5. Check your residence record if you plan to come back. Argentine temporary or permanent immigration status, DNI validity and Argentine tax residence are not interchangeable. A long absence can affect your immigration status; record your exit date and check the specific rules attached to your residence category with Dirección Nacional de Migraciones (national migration authority). Do not discard your DNI merely because you have moved.

If you own an Argentine property or keep Argentine rental income after leaving, retain the title, purchase and improvement records and arrange a local contact for bills and declarations. A UK return can change how foreign rent and gains are reported to HMRC; the UK–Argentina double taxation treaty guide explains the two-country starting point.

3. Ship possessions, or travel light

HMRC's Transfer of Residence (ToR) relief can exempt qualifying personal goods from import duty and VAT when you transfer your normal home to Great Britain. Broad conditions include normally living outside the UK for at least 12 consecutive months and having possessed and used the goods for at least 6 months before the move; exclusions and different rules apply to some items. Submit the ToR1 application to HMRC and give the approval reference to your mover or customs agent before clearance. It is relief for eligible goods, not a general permission to bring restricted items.

For each consignment, make a numbered inventory in English with estimated values, description, ownership dates and any serial numbers. Keep invoices for recent electronics and receipts for valuable goods; flag anything new, commercial, alcoholic or motorised to the carrier for separate customs treatment. Compare three costs rather than only the freight quote: collection and packing in Argentina, customs/handling on arrival, and delivery to your eventual UK address. A small shipment can be uneconomic if you will be in temporary accommodation for months.

The GB customs route is not automatically the route for Northern Ireland: use the relevant HMRC guidance for your destination before making the application. A household that left Britain less than 12 months ago should not budget for relief without checking the exception or paying the estimated charges. Store an electronic copy of your inventory and immigration evidence somewhere accessible without your Argentine phone.

4. Re-establish healthcare, housing and school

1. Arrange continuity of treatment before flying. Ask your Argentine clinician for a summary with diagnosis, test results, vaccination history and drug names in their generic form, plus an adequate lawful travel supply. UK prescriptions and brands are not interchangeable automatically; a UK GP must assess ongoing prescriptions. For urgent care in England, NHS 111 can direct you; call 999 for a life-threatening emergency. Healthcare arrangements differ in Scotland, Wales and Northern Ireland.
2. Register with a GP after arrival. NHS entitlement is based on being ordinarily resident in the UK, not simply holding a British passport or having once paid National Insurance. When you move back to live in the UK you can access NHS care on the ordinary-residence basis; bring evidence of your move and identity if requested. In England you can register with a GP even if you do not yet have standard proof of address or ID; ask the practice for its registration process rather than postponing treatment. A visitor's entitlement is different. An Argentine prepaga does not transfer into the NHS.
3. Get an address and apply for school places. Speak to the local council's school admissions team in England, or the corresponding education authority elsewhere in the UK, as soon as your address and arrival date are known. An in-year place is not guaranteed at the nearest school. Bring the child's passport or immigration status, address evidence, previous reports, vaccination record and any special educational needs documentation. The academic year normally starts in September, unlike Argentina's March-to-December cycle; ask the receiving school how it will place a child crossing mid-year.
4. Restore your administration. Tell your bank, insurer, employer, council and DVLA of the new UK address where relevant. Check your driving entitlement before driving on an Argentine licence: it depends on licence type, when you became resident and which UK nation you settle in. If you claim means-tested benefits, confirm the residence and habitual-residence conditions of that specific benefit; British citizenship alone does not remove a waiting or eligibility test.

If you are still deciding whether to leave rather than already returning, see the moving to Argentina from the UK guide for the opposite direction.

5. Fix the UK and Argentine tax timeline

Do not file a second P85 on return. P85 reports leaving the UK; it does not grant non-resident status and is not the form for coming back. For a return, update your HMRC contact details, tell your employer or pension payer your correct details and complete Self Assessment if required. The Statutory Residence Test (SRT) determines UK tax residence separately for each UK tax year, using UK days, work, homes and ties. Split-year treatment is available only when you meet a specific case; it is not automatic merely because you landed in October. See the Statutory Residence Test guide.

A useful starting worksheet has four columns: date, country at midnight, income received, and source of income. Add the date your Argentine home ceased to be available and the date a UK home became available. Keep payslips, rental statements, pension statements and travel records for both countries. If Self Assessment applies, the residence pages SA109 are normally where you give residence and split-year information alongside the main return. The UK–Argentina tax convention exists, but it does not exempt everything from tax: the tax treatment of salary, pensions, rent and gains differs. Match relief claims to the correct income type and residence period rather than paying twice and hoping for an automatic refund.

If you retain UK property, update your letting agent about your return. The Non-Resident Landlord scheme may have permitted rent without tax deducted under an NRL1 approval while you lived abroad; tell HMRC and the agent when you stop being a non-resident landlord, then include taxable rental profit in any required UK return. If you sell UK residential property while still non-resident, a UK property disposal return can be due within 60 days of completion, even if you expect little or no tax. Your return date matters: do not assume a sale in the transition month falls wholly under the rules for UK residents.

Tell DWP's International Pension Centre if you receive a UK State Pension abroad and change residence or bank details. Argentina is a country where annual State Pension increases are normally frozen while you live there; once you are living in the UK, ask DWP to reassess the rate from the appropriate date. The full new State Pension is £241.30 a week in 2026/27, but your own award depends on your National Insurance record and pension category; that figure is not a guarantee of what DWP will pay you.

Worked return: an October move

Take two British citizens and their nine-year-old child who have rented in Buenos Aires for two years. They plan to land in Manchester on 1 October 2026 and own their furniture, bought 18 months earlier. The adults check three passports, obtain the child's school reports and vaccination record, give notice under the signed Argentine lease and seek a deposit-accounting date before closing anything. Because the household has lived outside Britain for more than 12 months and used the furniture for more than 6 months, it starts a ToR1 application and prepares an itemised inventory; that does not make new purchases automatically eligible.

One adult receives a hypothetical £200 a week UK State Pension at a frozen overseas rate: £10,400 a year, or roughly £867 a month before any reassessment on UK residence. They tell DWP the actual arrival date rather than assuming the published full-rate figure applies. They also retained a UK flat let for £900 a month, or £10,800 gross annually. They notify their agent and HMRC of their return and obtain the rental expense and tax-deduction statements; gross rent is not taxable profit. For tax they log UK days from 6 April 2026 to 5 April 2027, check whether a split-year case fits and separately review Argentine receipts for the 2026 calendar year. The school admissions team, not the airline or the former school, decides what local place is available after the move.

Avoid the expensive shortcuts

• Do not use an Argentine partner's visitor entry as a trial settlement route. Sort the relevant UK permission before committing to freight and a tenancy.
• Do not assume ToR covers every box. Six months' use, twelve months abroad and item exclusions matter; newer goods can attract charges.
• Do not equate entry, NHS access and tax residence. They follow different rules and different evidence.
• Do not close every Argentine account at the airport. Leave a route for tax, deposit and billing settlements, then close it deliberately with retained statements.
• Do not assume the tax treaty or an Argentine tax payment eliminates UK reporting. Work through the income categories and dates on both returns.

If you are returning to Northern Ireland or moving with a non-British partner, check the separate customs or immigration route before relying on the Great Britain goods and British-citizen assumptions above. For a return to Argentina after a short UK visit rather than a permanent move, this checklist's healthcare and tax-reset steps may not apply.
