If my wife moves to the UK for 9 months in the same calendar year and becomes UK tax resident is she liable for our USA worldwide investment income by HMRC?
She does not work, I work in USA. We both live in US (2 homes) are US & UK dual citizens. We are originally from UK. We do not own any home in UK.
Typically we visit UK for 30 days a year. We have been tax resident in USA for 14 years. Investments are predominantly USA. We did not have any issue in past as the visits were limited in number of days.
My worry is that despite myself continuing to live and work in the USA whilst my wife is planning to move to UK for 9 months to look after a dying parent. Does the 183 day rule apply, my wife will [may?] become UK tax resident.
As I understand, due to our marriage, all my working income, capital gains on home or investment sale and investment income (bonds and dividends) in the USA will be recognized by HMRC as worldwide income and therefore taxable in UK.
The plan would be to transfer 10K or so into the UK for my wife to live on whilst is is there. She will not be working. Most US investments are typically in joint accounts. Thx
