Hi,
The guidance below advises that an individual will have an accommodation tie for a tax year if they have a place to live in the UK and it is available for a continuous period of 91 days or more and they spend 1 night there during that tax year, or, if it is the home of a close relative, they spend 16 or more nights there during the year.
Your wife living in her home does not count as an accommodation tie for you. However, if you meet the criteria in the following guidance you will have an accommodation tie.
RDRM11550 - Residence: The SRT: Accommodation tie
Thank you.
