I'm a long term permanent resident of the UK, but still a Canadian passport holder, and don't have a UK passport yet (by choice, I am eligible) When I receive a hand pay, I've tried to offer my UK drivers licence as ID, but the casino has always insisted on my passport, after which seeing it is issued by Canada, I'm taxed 30%. For those who don't know, the UK has a tax treaty with the USA where no tax is payable on gabling wins. So, given that I haven't lived in Canada for over 10 years, and have no taxable assets in Canada, and therefore haven't filed tax there, but do file tax returns in the UK: 1. Am I eligible for the UK tax treaty? 2. If so, do I have to file to get it back at the end of the year, or is there something I can do to mitigate this now, and be treated as a UK taxpayer?
