I have Capital Gains Tax to pay.
Luckily my previous years RA contributions that have rolled over and my increased 2016 contributions will cancel out half the CGT amount owed. I will only calculate and save, but not submit, I have until 24 November 2017 to build up the required funds (or see what bonus is like in Sept) and submit
Good luck!
I have never had a job with a bonus, never mind one in September :crylaugh:
