"In what circumstances would I become non-resident?
A3. Normally if you leave the UK to work abroad full-time, you will become not resident and not ordinarily resident in the UK if:
- your absence and employment from the UK covers a complete tax year (that is 6 April to 5 April)
- you spend less than 183 days in the UK during the tax year
- your visits to the UK do not average 91 days or more a tax year over a maximum of four years
From 6 April 2008, days when you are in the UK at the end of the day, that is midnight, are normally counted as days spent in the UK".
