I'm a 40% tax payer, who jumped down a rabbit hole trying to work out what the impact on take-home would be if I bumped my work pension contributions up by £250 a month. Now I'm wondering if I have been missing out on a massive chunk of change via Self-Assessment for the past few years. Please can somebody wiser than I am set me on the right track?
I pay into two pots every month: my workplace pension (£400 matched by employer, plus an additional voluntary contribution of £350). I also pay £100 into a small personal pension.
Now I am reading online that, in addition to getting 20% tax relief at source / via my payslip, I should have been actively claiming an additional 20% via my annual SelfAssessment form for HMRC.
Does this this sound right? Would it not have been credited automatically?? Either via my payslip or the online self-assessment form?
If you know anything about this and can point me in the right direction, thank you!
