Four questions to answer separately
Begin with your personal tax residence under UK law and the rules of the destination country. Being resident in one country does not automatically mean you have ceased residence everywhere else.
Then examine where you physically work, where your company is controlled and whether its overseas activity creates a permanent establishment. Finally, confirm that your immigration status permits the work you intend to perform.
| Question | Why it matters | Evidence to retain |
|---|---|---|
| Where are you personally tax resident? | Determines the normal scope of personal taxation and access to treaty relief. | Travel calendar, homes, workdays and family ties. |
| Where is each income source? | Salary, directors’ fees, dividends, rent and gains can follow different rules. | Contracts, payslips, dividend vouchers and transaction records. |
| Where is the company managed? | Management abroad can create company-residence or permanent-establishment questions. | Board papers, decision records, contracts and authority limits. |
| What work may you legally perform? | A residence visa is not always a general permission to work or run a local business. | Visa conditions, work permit and professional advice. |
Do not plan from a single day-count rule
The UK Statutory Residence Test combines automatic tests with UK ties and day limits. A commonly repeated 183-day rule is only one part of the analysis.
Destination-country residence rules may use a different tax year and different counting method. A person can therefore be resident under both countries’ domestic rules before a tax treaty is considered.
Keeping a UK limited company
A UK company does not disappear when its owner leaves Britain. Companies House filings, Corporation Tax, accounts, records, banking and director duties continue.
The company may also acquire obligations in the country from which it is being managed or where staff, premises, customers or contract activity are located. Personal non-residence is not a shortcut that automatically changes the company’s tax residence.
Plan before the departure date
Record the expected departure date, UK visits, accommodation, work pattern and source of each payment. Review the structure before signing a long lease, taking local customers or hiring overseas staff.
For material decisions, use advisers who understand both countries and will coordinate their conclusions. Two isolated domestic opinions can leave the interaction between the systems unanswered.
- Model at least the departure year and the following full tax year
- Separate personal income from company revenue and cash transfers
- Document who makes strategic and day-to-day company decisions
- Check immigration and work rights before commencing activity
- Create an annual calendar for filings, payments and evidence

Frequently asked questions
Does moving abroad make me non-UK resident immediately?
Not automatically. Apply the Statutory Residence Test to the entire UK tax year and then consider whether split-year treatment applies.
Your departure date alone does not decide residence.
Can I keep my UK limited company after moving abroad?
Usually, yes. The company still has UK legal, filing and tax obligations, while the way it is managed and operated overseas may create additional obligations in the destination country.
Can I be tax resident in two countries?
Yes. Both countries’ domestic rules can treat you as resident.
A relevant tax treaty may then contain tie-breaker provisions and rules allocating taxing rights, but it does not erase all filing duties.
