During the 17-18 tax year, my husband had no income in Hong Kong. Therefore when I completed my 17-18 tax return in May 18, I declared this and got the benefit of his personal allowance. I think my 18-19 provisional tax assumes this status quo.
My husband started a new job in HK in May 2018. This is the first time he has been employed in HK, and so he's now received a notice from the Revenue asking him to complete a provisional tax return for 18-19. Is it going to confuse the Revenue if he completes this now as requested and pays his provisional tax next January, before I complete my 18-19 actual tax return in May 19 which I assume will result in me getting a balancing bill as I'll no longer be able to claim his provisional allowance?
We'll both be earning over the personal allowance threshold so would there be a benefit to filing jointly?
