Statutory Residence Test (SRT)

The UK’s SRT rules are detailed and nuanced. We’ll assess your day count, ties to the UK, work patterns and living arrangements to confirm whether you are a UK tax resident.

If you’re eligible for split-year treatment, we’ll make sure it’s applied correctly to avoid paying tax on overseas income unnecessarily.

Cross-Border Income

Have income from property, investments or pensions abroad? We’ll help you declare it correctly, avoid double taxation, and make sure your affairs are structured efficiently.

We’ll also guide you on when and how to report overseas assets and income, and support you through HMRC’s Worldwide Disclosure Facility if you need to catch up on undeclared income. While we only deal with UK tax, we can always put you in touch with tax experts from other countries.

FAQs

  • 1. How do I know if I'm a UK tax resident?

    Your UK tax residency is decided by the Statutory Residence Test. It looks at how many days you spend in the UK and your ties here, like family, a home, work and time spent in previous years. The rules are detailed and easy to get wrong, so we'll go through your circumstances and confirm your status clearly.

  • 2. I'm moving to or leaving the UK partway through the tax year. How am I taxed?

    You may qualify for split-year treatment. This divides the tax year into a UK part and an overseas part, so you're only taxed as a UK resident for the time you actually live here. It only applies in specific situations, so we'll check whether you qualify and make sure it's claimed correctly.

  • 3. Do I need to pay UK tax on my overseas income?

    UK residents are generally taxed on their worldwide income and gains. However, people arriving in the UK after at least 10 years of living abroad may be able to claim relief on foreign income and gains for their first four years here. Double taxation agreements can also stop you being taxed twice on the same income. We'll work out what applies to you and report it correctly.

  • 4. What happened to non-dom status?

    The non-dom regime and the remittance basis ended on 6 April 2025. They've been replaced by a new residence-based system, including the four-year foreign income and gains regime for new arrivals and changes to how Inheritance Tax applies to people with international connections. If you were previously taxed as a non-dom, we can review your position and help you plan under the new rules.

  • 5. What if I haven't declared overseas income in the past?

    HMRC's Worldwide Disclosure Facility lets you come forward voluntarily and bring your affairs up to date. Making a voluntary disclosure usually leads to lower penalties than waiting for HMRC to contact you. We can calculate what's owed, prepare the disclosure and deal with HMRC for you.
