Nomad Capitalist R&D: How to Lower Your Tax Bill as UK Citizen

If you are a UK tax resident planning to leave the country, the key to a tax‑efficient exit is understanding how HMRC determines residency and how to handle any UK‑based business interests.

How HMRC decides residency

HMRC applies three sequential tests:

1. Automatic non‑resident test – you are automatically non‑resident if any of the following apply:

   • You were not a UK resident in any of the previous three tax years and you spend fewer than 46 days in the UK in the current tax year.
   • You were a UK resident in at least one of the previous three tax years and you spend fewer than 16 days in the UK in the current tax year.
   • You work full‑time abroad, are present in the UK for fewer than 91 days, and spend no more than 30 days working in the UK.

2. Automatic resident test – you are automatically resident if any of the following apply:

   • You spend 183 days or more in the UK in the tax year.
   • You have only one home, and that home is in the UK.
   • You carry out full‑time work in the UK.

3. Sufficient ties test – if neither of the above tests is met, HMRC looks at the number of “ties” you maintain with the UK. The more ties you have, the more likely you will be treated as resident. Relevant ties include:

   • Family – a spouse, civil partner, or minor children who remain in the UK.
   • Accommodation – having a place to live in the UK that you use during the tax year.
   • Substantial work – 40 workdays (or more than three hours per day) of UK employment or self‑employment.
   • Previous UK presence – more than 90 days in either of the two preceding tax years.
   • Comparative presence – spending more days in the UK than in any other single country during the tax year.

Other connections that may be considered are UK bank accounts, credit cards, brokerage accounts, insurance policies, registered vehicles, storage facilities, mail‑box services, phone contracts, and similar subscriptions.

Intent matters. HMRC expects a genuine, permanent move rather than a temporary vacation or gap year. A common practical guideline is to remain non‑resident for at least five years before returning, to avoid retroactive tax assessments on earlier earnings or gains.

Handling a UK company when you become non‑resident

If you own a UK‑registered company, you have several options:

• Make the company dormant or liquidate it.

  • As a non‑resident you can extract cash via dividends or a capital‑gain‑type liquidation.
  • Dividends received as a non‑resident are generally free of UK tax; capital gains on the liquidation are also exempt for individuals.

• Keep the company operating but step down as director.

  • Remain only as a shareholder.
  • Dividends taken as a shareholder are taxed in the UK, but they will be subject to tax in your new country of residence, so you must consider double‑taxation relief.

• Create an offshore (foreign) company and invoice the UK company for services.

  • Invoices must reflect arm‑length market value; HMRC may challenge amounts that appear artificially high.
  • Proper documentation and transfer‑pricing justification are essential to avoid anti‑avoidance investigations.

Tax implications of the move

• No exit tax for individuals. The UK does not levy a “departure tax” on personal assets when you cease residency.
• Corporate exit taxes may apply. Before liquidating a UK company you may need to settle corporation tax on any gains realized.
• Cryptocurrency and other personal investments. For individuals, capital gains on crypto, stocks, options, etc., are not subject to an exit charge. If those assets are held in a company, normal corporation‑tax rules apply.
• Dividends. Non‑resident individuals are not subject to UK dividend withholding tax, but the receiving country may tax the dividend.

Practical steps to minimise risk

• Count days precisely. HMRC treats any day you are present in the UK at midnight as a full day. Build a buffer of several days below the relevant thresholds.
• Sever ties where possible.
  • Move family members abroad.
  • Cancel or sell UK accommodation.
  • Close or transfer UK bank accounts and credit facilities.
  • End UK‑based contracts (phone, internet, storage, etc.).
• Document your intent. Keep records of the move (e.g., lease termination, school enrolment for children abroad, employment contracts overseas).
• Seek professional advice. The residency tests are fact‑specific; a tax adviser can model different scenarios, especially when you have complex structures or significant assets.

By applying the automatic tests, managing the sufficient ties, and handling any UK corporate interests with arm‑length transactions, you can achieve a clean, tax‑efficient departure from the UK.
