All British expats need to be aware of this test and how it applies to them. It is possible for the taxman to determine that you are UK resident, even though you believe you are resident elsewhere. The test is a definite process to determine your UK residence status – a status that applies for income tax, capital gains tax and inheritance tax purposes.

To assess your residence status, you need to work through the following three tests in order. If you are non-UK resident under the first test, the other two will not apply. If the second applies, the third is ignored.

Whether you are an ‘arriver’ or ‘leaver’ plays an important part, and this is based on your residence status the previous three years. To determine residence for years prior to 2013/2014, the old rules continue to apply.

Note that all references to ‘years’ are a UK tax year, and a day in the UK is counted if you are there at midnight.

1. Automatic overseas test 

 If you meet any of the following conditions, you are automatically treated as not resident in the UK:

• You were not resident in the UK in any of the previous three UK tax years, and are present in the UK for fewer than 46 days in the current year.
• You were resident in one or more of the previous three years, and present for fewer than 16 days in the current year.
• You work overseas full time and spend no more than 30 days working in the UK (work day = three or more hours), and no more than 90 days in the UK in the relevant year.

2. Automatic residence test

You are automatically treated as resident in the UK if you meet any of the following conditions:

• You spend at least 183 days in the UK in the current tax year.
• Your only or main home is in the UK.
• You work full time in the UK for at least 365 days without a significant break from work of 31 days or more, subject to certain conditions.

An ‘only or main home’ is property available to be used by you for at least 91 days, if you have actually used it for 30 separate days or more.

3. Sufficient ties test

 If your residence position is not determined by the above two tests, the number of days you can spend in the UK in the tax year without being UK resident depends on if you are an arriver or leaver, and the number of connecting ties you have with the UK. These are:

• Family – spouse and/or minor children live in the UK
• Accessible accommodation – if available to you for at least 91 days and you spend just one night there
• Work – if you spend 40 or more days working in the UK
• 90 days – if you spent 90 days or more in the UK in either of the two previous tax years
• Country – if you spend more days in the UK than any other single country (only applies to ‘leavers’).

This test operates on a sliding scale, so the more ties you have with the UK, the less time you can spend onshore without becoming UK resident. Conversely, the fewer ties you have, the more days you can spend there before becoming UK resident.
