Moving from the UK to Mexico (2026): Complete Guide

Relocating from the United Kingdom to Mexico means clearing two separate customs systems that don’t talk to each other: HM Revenue & Customs (HMRC) on the way out of Great Britain, and Mexico’s Agencia Nacional de Aduanas de México (ANAM, operating under SAT) on the way in. This guide is written for a UK resident — British national or foreign resident of the UK — planning a household move to Mexico, and covers both halves of the journey: what HMRC and UK authorities require before you leave, and what Mexican customs and immigration (INM) require before your belongings, pets, or vehicle can legally enter the country. A short final section covers the reverse move, Mexico back to the UK.

Key takeaways

• Whether Mexican customs will let your household goods in duty-free depends on your immigration status. A tourist FMM permit does not qualify at all. Residente permanente holders get a definitive, duty-free menaje de casa import; residente temporal holders also get duty-free treatment, but on a temporary basis tied to their visa — in principle you commit to re-exporting the goods (or regularising them) if you later leave Mexico or your status lapses. The visa must generally be obtained at a Mexican consulate before you travel (SRE, Visa de residencia temporal; ANAM, Menaje de casa).
• On the UK side, there is no blanket "personal effects" exemption for a household shipment: it needs a standard customs export declaration to HMRC, normally lodged electronically by your removals company or a customs agent acting as your indirect representative (gov.uk, Export goods from the UK: step by step).
• Telling HMRC you’re leaving (form P85, or the residence pages of your Self Assessment return) does not by itself make you non-UK tax resident — that is determined separately by the Statutory Residence Test (gov.uk, P85 guidance; gov.uk, Tax if you leave the UK).
• Mexico’s menaje de casa relief runs on a strict clock: goods must have been owned for at least 6 months, and the import must happen within 3 months before, or 6 months after, your qualifying entry to Mexico (ANAM, Menaje de casa; ANAM, Trámites menaje de casa).
• Carrying £10,000 or more in cash into or out of Great Britain must be declared to Border Force; Mexico separately requires declaration of cash and negotiable instruments over US $10,000 on arrival or departure, using ANAM’s official cash-declaration forms (gov.uk, Take cash in and out of the UK; ANAM, Declaración de dinero).
• Pets need microchipping, rabies vaccination and an Export Health Certificate (EHC) — signed off by an Official Veterinarian — to leave the UK for a non-listed country such as Mexico, then a Certificado Zoosanitario para Importación (CZI) issued by SENASICA on arrival (gov.uk, travelling to a non-EU country; SENASICA, Tu mascota viaja contigo).
• Your own car cannot travel under the menaje de casa exemption — vehicles are explicitly excluded — and instead need a Banjercito Temporary Vehicle Import Permit whose validity, for foreign residents, tracks your immigration status (Banjercito TIV system, gob.mx; ANAM, Menaje de casa).
• If you ever move back, HMRC’s Transfer of Residence relief (ToR1) allows duty- and VAT-free import of your belongings into the UK (gov.uk, Transfer of residence to Great Britain).

1. How your Mexican immigration status determines your customs treatment

Everything on the Mexican side flows from your visa. Arriving as a tourist on an FMM (up to 180 days) gives you no entitlement to import household goods duty-free — you’re treated as a visitor bringing personal luggage, not someone transferring residence. To use the menaje de casa exemption you need a residente temporal (temporary resident, valid roughly 6 months to 4 years) or residente permanente visa issued by Mexico’s Instituto Nacional de Migración (INM), applied for at a Mexican consulate outside the country before you travel, then exchanged for a physical resident card at an INM office within 30 days of entering Mexico (SRE, Visa de residencia temporal).

It’s worth understanding that the two visa routes are not treated identically. A residente permanente visa gives you a definitive, permanent duty-free import of your household goods. A residente temporal visa gives you duty-free treatment too, but on a temporary basis tied to the length of your visa status: in principle you are committing to re-export the goods, or regularise their status, if you later leave Mexico or your residency lapses, rather than owning them free and clear the way a permanent resident does (ANAM, Menaje de casa; ANAM, Trámites menaje de casa).

Because the menaje de casa inventory must also be validated at a Mexican consulate before your goods ship, the practical sequence for someone moving from the UK is: secure the resident visa first, then process the household-goods paperwork, then ship. Arriving with a container already in transit before your visa is approved risks losing the duty-free exemption entirely.

2. The UK export side: HMRC, deregistration and tax exit

The relevant UK authority is HMRC, with Border Force enforcing controls at the point of export. There is no single "moving abroad" office — instead, several separate notifications:

• Tell HMRC you’re leaving using form P85 ("Leaving the UK – getting your tax right"), or via the residence section (SA109) of your Self Assessment return if you already file one (gov.uk, P85 guidance).
• Tax residency is not decided by P85 alone. Your status is governed by the Statutory Residence Test, with split-year treatment potentially applying for the tax year you leave (gov.uk, Tax if you leave the UK).
• Tell your local council so you stop being charged Council Tax, and review your position on the electoral register and NHS entitlement as part of the standard moving-abroad checklist (gov.uk, Moving, living or retiring abroad).
• Export declarations: since Brexit, exports from Great Britain require a customs declaration to HMRC, whatever the goods. There is no general exemption for "personal effects" — a full household shipment needs a proper export declaration, normally lodged electronically on your behalf by your removals company or a customs agent acting as your indirect representative, using an EORI number (gov.uk, Export goods from the UK: step by step).
• Cash: if you or your household are carrying £10,000 or more (or the equivalent, including combined family totals) out of Great Britain, it must be declared to Border Force before travel (gov.uk, Take cash in and out of the UK).

3. Ports and transit — real routings, industry estimates

For sea freight, UK removals shipments to Mexico are typically consolidated or containerised through Felixstowe (the UK’s largest container port), Southampton, or London Gateway, with Tilbury used by some operators for smaller loads. Airfreight typically routes through London Heathrow. On the Mexican side, sea shipments usually land at Veracruz or Altamira on the Gulf coast, or Manzanillo on the Pacific, while airfreight clears through Mexico City International Airport (AICM) or the newer Felipe Ángeles International Airport (AIFA).

The following transit times are freight-industry estimates only, not published by any government agency, and vary by carrier, season and consolidation schedule: full-container sea freight from a UK port to Veracruz or Altamira typically runs 6–9 weeks door-to-door once customs clearance and menaje de casa formalities are included; less-than-container-load (shared groupage) shipments often add several weeks for consolidation. Airfreight is faster but far more expensive for a full household — typically 1–2 weeks including Mexican customs clearance.

4. The Mexico import side: customs form and process

On arrival, every passenger completes the Declaración de Aduana para Pasajeros Procedentes del Extranjero (customs declaration for passengers arriving from abroad) and passes through a randomised selection system — commonly known as the "semáforo fiscal" — used at many ports of entry to decide whether baggage is physically inspected (ANAM, Pasajeros). For your household shipment specifically, the menaje de casa process runs through your Mexican consulate and then a customs broker (agente aduanal) at the point of entry: you present an itemised inventory, in Spanish, in the required format, together with proof the goods were owned for at least 6 months, and the shipment must enter within the 3-months-before/6-months-after window tied to your qualifying entry date (ANAM, Menaje de casa; ANAM, Trámites menaje de casa). As covered above, whether that exemption is definitive or temporary depends on whether you hold residente permanente or residente temporal status. Goods used for commercial or industrial purposes abroad, and vehicles, are explicitly excluded from the relief. Separately, any merchandise you bring that exceeds your personal duty-free allowance is subject to declaration and duty (ANAM, Declaración de mercancía).

5. Pets: rules at both ends

Leaving the UK: your dog or cat must be microchipped and vaccinated against rabies. Because Mexico is not on the UK’s list of countries covered by the simpler "GB pet health certificate" route, you instead need an Export Health Certificate (EHC): an Official Veterinarian confirms your pet meets Mexico’s entry requirements, and the paperwork is arranged through the export health certificate application process before you travel — check for any additional country-specific requirements before booking your vet appointment (gov.uk, travelling to a non-EU country).

Entering Mexico: Mexico recognises only dogs and cats as pets for import purposes. On arrival you request a Certificado Zoosanitario para Importación (CZI) from SENASICA staff at the port, airport or border crossing, and present a certificate of good health (valid no more than 15 days from issue) from a vet confirming rabies vaccination status — animals under 3 months old are exempt from the vaccine requirement. Your pet is also physically inspected on arrival (SENASICA, Tu mascota viaja contigo).

6. Vehicles, money, and things people forget

Vehicles: your UK car cannot travel under menaje de casa — it is explicitly excluded from that relief (ANAM, Menaje de casa). Instead, foreign-plated vehicles need a Temporary Vehicle Import Permit (TIV) issued through Banjercito, applied for online, at a Mexican consulate up to six months ahead, or at the border; for foreign residents, the permit’s validity tracks your immigration status rather than the fixed multiple-entry period given to short-term visitors (Banjercito TIV system, gob.mx).

Money: declare £10,000+ leaving Great Britain (gov.uk) and US $10,000+ arriving in or leaving Mexico. On arrival this is declared on the passenger customs form itself; amounts over the threshold require an additional detailed cash-declaration form (ANAM, Declaración de dinero).

What people forget: the menaje de casa entry window is calculated from your first qualifying entry to Mexico, not from when your visa was issued — arrive, then delay shipping for more than 6 months, and you lose the duty-free exemption. Equally, shipping your container before your resident visa is approved leaves you with no relief to claim against. And people also assume a temporary resident’s duty-free import is identical to a permanent resident’s — it isn’t: temporary status carries an in-principle obligation to eventually re-export or regularise the goods, which a residente permanente import does not. On the UK side, people often assume "personal effects" are automatically exempt from export paperwork — in practice a household shipment still needs a standard export declaration lodged through a customs agent or your removals company, because there is no blanket personal-effects exemption from the declaration requirement itself (gov.uk, Export goods from the UK: step by step).

How Flyto handles your UK to Mexico move

Flyto operates its own offices, warehouses, teams and vehicles across Northern, Central and Southern Europe, so the UK collection, packing and export documentation on your move are handled in-house rather than handed off blind. For the ocean crossing and the Mexican side, we work through a carefully vetted network of subcontracted carriers and trusted local partners on the ground in Mexico, who handle the menaje de casa consulate process, customs brokerage and last-mile delivery — so you get one point of contact managing both halves of a move that legally involves two entirely separate customs systems.

Frequently asked questions

Do I need a Mexican residency visa before I can ship my household goods duty-free?
Yes. The menaje de casa exemption is only available to holders of a residente temporal or residente permanente visa; a tourist FMM does not qualify. Note that a permanent resident gets a definitive, permanent duty-free import, while a temporary resident gets duty-free treatment tied to their visa status (SRE; ANAM).

Does filing form P85 make me non-UK tax resident?
No — P85 notifies HMRC you’re leaving, but your actual tax residence status is determined by the Statutory Residence Test, independently of the form (gov.uk).

Can I bring my car to Mexico permanently?
Not under household-goods relief — vehicles are excluded from menaje de casa. You’ll instead need a Banjercito temporary import permit, and its validity is linked to your residency status, not permanent import (Banjercito, gob.mx).

How much cash can I carry without declaring it?
Under £10,000 leaving Great Britain, and under US $10,000 entering or leaving Mexico. Above those thresholds, declaration is mandatory in both directions (gov.uk; ANAM).

What paperwork does my dog or cat need?
Leaving the UK: microchip, rabies vaccination, and — since Mexico isn’t on the UK’s listed-country route — an Export Health Certificate (EHC) signed off by an Official Veterinarian (gov.uk). Entering Mexico: a SENASICA Certificado Zoosanitario para Importación, obtained on arrival, backed by a recent vet health certificate (SENASICA).

If I later move back to the UK, do I pay duty on my belongings again?
Not necessarily — HMRC’s Transfer of Residence relief (ToR1) lets returning residents import personal belongings free of duty and VAT, subject to ownership and use conditions (gov.uk; gov.uk, ToR1 application).
