TL;DR
Leaving the UK after a period of residence involves a sequence of tax, financial, immigration and practical decisions: tax residence status, pension treatment, property and investment positions, NHS and council services, and timing of departure. This guide explains each in order and the dependencies between them.
Key facts
- UK tax residence is determined by the Statutory Residence Test, not by visa status or physical departure alone.
- Split-year treatment may apply to the year of departure if HMRC's conditions are met.
- Indefinite Leave to Remain lapses after 2 years of absence from the UK; British citizenship does not.
- UK pensions, ISAs and investment products have specific cross-border treatment depending on the country of new residence.
The order of decisions before departure
Departure planning typically begins 6-12 months before the move. The first decisions are usually around tax: when is the UK tax residence position changing, will split-year apply, what are the disposal positions on UK assets. The second tier is financial: pensions, ISAs, investment accounts, property.
Immigration considerations are next: ILR holders need to plan for the 2-year absence rule, British citizens can leave without immigration consequence, those still on a visa need to consider whether they will return or end the visa cleanly.
Practical matters (NHS, council, utilities, schools) sit on the same timeline. Most can be addressed in the final month before departure; some (school exit, property sale) need longer.
UK tax residence and the Statutory Residence Test
The Statutory Residence Test (SRT) in Finance Act 2013 determines UK tax residence. The test has automatic UK tests, automatic overseas tests, and sufficient ties tests. The number of days spent in the UK in the tax year combines with other factors (family, work, accommodation) to determine residence.
For most departures, becoming non-resident is a function of leaving for work abroad or substantially reducing UK days. Split-year treatment applies in some circumstances, treating the year as a UK part (resident) and a non-UK part (non-resident). HMRC's guidance manuals cover the detail.
Pensions, ISAs and investment accounts
UK workplace pensions remain in place after departure; the holder can continue receiving them at retirement. Some pensions can be transferred to overseas pension schemes (Qualifying Recognised Overseas Pension Schemes, or QROPS) but transfers are heavily restricted by HMRC and often subject to charges.
ISAs can be retained but no new contributions can be made after the holder ceases to be UK resident. Investment platforms vary in their approach to non-resident accounts; some restrict service, others continue. Some accounts are closed by the provider.
Property and other UK assets
UK property held at departure remains a UK-source asset for tax purposes. Capital gains on UK residential property are charged to non-residents under the Non-Resident Capital Gains Tax rules. Rental income is taxable as UK-source income; the Non-Resident Landlord Scheme governs collection.
Selling UK property before departure simplifies the tax position. Keeping the property and letting it requires registration under the NRL scheme. Other UK assets (shares in UK companies, UK bank accounts) generally remain accessible after departure.
Immigration status on departure
British citizens face no immigration consequence from departure. ILR holders need to be aware of the 2-year absence rule: absence of more than 2 years leads to lapse of ILR, requiring a Returning Resident visa to re-enter. Visa holders who do not intend to return should not renew or extend; visa expiry is the clean end of UK status.
Some departing residents naturalise as British citizens before leaving to remove the absence-related risks. Naturalisation requires 12 months of ILR (or earlier for spouses of British citizens), good character, and the Life in the UK test and B1 English.
Practical departure tasks
Final month: cancel utilities, set up mail forwarding, notify HMRC of departure on form P85, deregister from local authority for council tax, GP record transfer or exit, school exit forms for children, bank account decisions (close, keep, or convert to non-resident).
Shipping belongings: international moving company quotes, customs documentation, marine insurance. The Shipping Belongings article on this site covers options and timing. Pets: reverse of arrival rules; the destination country's import requirements apply.
Country-specific receiving rules
Each receiving country has its own tax residence, import and immigration rules. Tax residence in the destination often coincides with becoming UK non-resident, with the Double Taxation Treaty between the UK and the destination allocating taxing rights.
Returning to a country of citizenship usually has the simplest immigration position. Moving to a new country requires its own visa or residence permit, with its own evidence and process. Most major destinations have established routes for skilled workers and family migration.
Pre-departure: 6-12 months out
Tax planning: review UK tax position with a qualified adviser. The Statutory Residence Test determines when UK tax residence ends; split-year treatment can apply in the year of departure. Decisions about timing of property sales, pension actions, and major financial events affect the tax position significantly.
Pension review: assess what to do with UK workplace and personal pensions. Most pensions can be left in the UK to grow; QROPS transfers are restricted and often subject to the Overseas Transfer Charge of 25%. Specialist regulated advice is essential.
Property decisions: sell or keep? Selling before becoming UK non-resident keeps any gain within UK CGT with potential PPR relief; selling after triggers Non-Resident CGT with 60-day return filing. Renting through the Non-Resident Landlord Scheme is the alternative for keeping the property.
Investment account review: which UK accounts to keep, which to close? ISAs continue tax-free in the UK but the foreign country may tax them. UK brokerages vary in their treatment of non-resident customers; some restrict service.
Document collection: gather UK records that may be hard to access later: P60s, tax returns, pension statements, ISA documents, property deeds, education certificates of children.
3-6 months out: the practical move
Notify HMRC of intended departure: form P85 is the main notification. Personal tax account should also reflect the departure address. Tax codes adjust accordingly.
Council tax: notify the local council of the move-out date. The council bills cease from move-out; any overpayment is refunded. Single-occupier discount or empty-property treatment may apply for any gap before the property is reoccupied.
Utilities: contact gas, electricity, water and broadband suppliers to give notice. Most require 30 days; final readings are taken on the move-out day with final bills issued shortly after.
Shipping arrangements: get quotes from international removers. The Transfer of Residence (TOR) application via HMRC's online service should be made before goods arrive at the UK port (or destination for outbound goods).
Pet arrangements: if pets are travelling, start the reverse-of-arrival process. Microchip, vaccination, and destination country's import requirements have their own timelines.
Final month: closing UK life
Property handover: tenancy end and deposit return, or property sale completion. The deposit protection scheme returns deposits within 10 days of agreement; disputes go to the scheme's ADR.
Cancel direct debits: at the merchant level for each subscription, not just at the bank. Subscriptions continue to attempt collection until they are cancelled at source.
Final tax submissions: prepare for the year-of-departure self-assessment (filed in the following tax year). Split-year claim and the UK-source income reporting are part of this.
Final NHS arrangements: notify GP of departure; medical records can be transferred internationally with the holder's request. NHS dental and ongoing treatments should be completed or transferred.
Goodbye logistics: final social arrangements, return of work equipment, school exit forms for children, club and membership cancellations. The final week typically involves practical and emotional handovers.
Cross-border tax position in the year of departure
UK tax in the year of departure: depends on the SRT. Split-year treatment can apply, treating the year as a UK part (resident) and an overseas part (non-resident). Cases 1-8 of Part 3 of Schedule 45 FA 2013 specify when each split-year case applies.
Country of new residence: typically taxes from the date of arrival (or earlier under their domestic rules). The interaction with UK tax depends on the bilateral Double Taxation Treaty.
Specific income types: UK employment income up to departure is taxable in the UK; income after departure (where work was done abroad) is typically not. UK rental income remains UK-taxable throughout. UK pensions follow the relevant DTT provisions; most allocate to the country of residence with credit for UK tax.
Capital gains: assets held at departure that are sold during a short non-residence period (less than 5 complete tax years) can be brought back into UK tax under the temporary non-residence rules. Longer absences clear this risk.
Immigration status considerations
British citizens: no immigration consequence from departure. Citizenship cannot lapse through absence.
ILR holders: 2-year absence rule. If leaving for more than 2 years continuously, ILR lapses; Returning Resident visa needed to re-enter and restore. Naturalising as a British citizen before extended absence removes this risk.
Visa holders during the visa: leaving permanently typically means not extending. The visa expires; the person is treated as having ended UK residence. Returning later requires a new visa application from abroad.
Family considerations: where some family members are British and others are visa holders, each is in a different immigration position. Coordinated departure planning accounts for each person's status.
Country-specific receiving rules and integration
Visa for new country: most receiving countries require a visa or residence permit. The new country's immigration rules apply; the UK has no role beyond providing the documentation (passport, criminal record certificates, qualifications evidence) the new country needs.
Returning to country of nationality: typically the simplest immigration position. The returning citizen has full rights; some countries require registration of return for specific purposes (tax residency, electoral roll, social security).
Tax residence in the new country: most countries determine tax residence by physical presence and connection tests similar to the UK SRT. The new country typically becomes the primary taxing jurisdiction shortly after arrival.
Banking and financial setup: opening accounts in the new country, transferring funds from the UK, setting up payment methods for ongoing UK obligations (rental income receipt, pension receipt). FX considerations affect timing of transfers.
Social integration: schools for children, social and community networks, healthcare provider registration. The reverse of arrival in the UK; each country has its own onboarding patterns.
Records and documentation for the leaving process
Document organisation: a structured folder system (physical or digital) for immigration documents reduces friction across the years of the visa. Categories: identity (passports, BRPs, eVisa records), employment (CoS, payslips, employer letters), finances (bank statements, tax returns), relationships (where applicable), education (where applicable), travel (boarding passes, hotel receipts).
Digital preservation: scan and back up all documents to secure cloud storage. Multiple backups (separate cloud, USB drive, family member's copy) protect against loss. Encryption is sensible for sensitive documents (tax records, financial statements).
Long-term retention: documents from the visa period are needed at extension, ILR, and potentially naturalisation. Keep documents for at least 6 years after the visa period; immigration records are often referenced years later.
Records during the qualifying period: from day one of the initial visa, track UK presence and absences for the eventual settlement calculation. Travel logs, employer travel records, and supporting evidence all build the documentary picture.
Using GOV.UK and official sources effectively
GOV.UK as the primary source: the UK government's single online portal for most public services. Immigration Rules, caseworker guidance, current fees and IHS rates, application forms, and updates are all on GOV.UK. The site is the authoritative reference for any current rule or process.
Subscribing to updates: GOV.UK allows email subscriptions to specific topics including immigration. Updates arrive when guidance is amended or new Statements of Changes are published. Practitioners and engaged applicants commonly subscribe.
Statements of Changes (SoCs): published on GOV.UK as PDF documents. Each SoC has a HC number identifying it; recent SoCs HC 590 of 2023, HC 1496 of 2023, HC 246 of 2024 introduced significant changes. The consolidated Immigration Rules on GOV.UK reflect the current text after all SoCs.
Modernised caseworker guidance: published separately from the Rules. Covers practical application; not binding but highly influential. Updates flow through new versions with effective dates.
ONS, HMRC and other primary data: GOV.UK aggregates data from across government. ONS migration statistics, HMRC tax and customs data, sectoral statistics from departments. The data underlies policy decisions and is publicly accessible.

Frequently asked questions
How do I leave the UK officially?
Notify HMRC by filing form P85 on departure (or via the self-assessment tax return covering the year of departure). Notify your local council to end council tax. Inform employers, banks, and other UK service providers. Hand back the BRP if no longer needed.
What happens to my UK ILR if I leave for more than 2 years?
ILR lapses after 2 continuous years of absence from the UK. To return, a Returning Resident visa is needed; if granted, ILR is restored. Naturalising as a British citizen before extended absence removes this risk.
Do I still pay UK tax after leaving?
Depending on the Statutory Residence Test. Becoming UK non-resident usually means UK-source income (rental, employment, pension) is still taxable in the UK; non-UK-source income is not. The country of new residence usually taxes worldwide income.
Can I keep my UK pension after leaving?
Yes. UK workplace and state pensions can be received at retirement regardless of where the holder lives. Some pensions can be transferred to overseas QROPS schemes but transfers are heavily restricted and often subject to charges; specialist advice is common.
How long before leaving should I start planning?
6-12 months for tax-efficient departures (split-year planning, pension transfers, property sales). 3-6 months for standard departures. Most practical tasks (utilities, council, schools) can be addressed in the final month.
