Hi there, I work across eu for a uk company, I have an office in belgium and home in both uk and brux. Belgium want me to pay belgium tax for the days I don't work in the uk. Ok so far. But my advice is that the double taxation treaty won't apply and that I will need to pay full belgium tax on income that i have already paid uk tax on. As this relates to 2009 I think the chances of getting the UK tax back are nil. Has anyone had any experience of this - will the belgium tax authorities give me a credit for the UK tax already paid and I pay the difference?
