I've just started to organise my personal finances - I have some money (~40k) depreciating away in a low interest savings account. I have a question that I've tried in vain to find an answer to on the googles.
My situation is that I'm a higher rate earner (I earn about 60k) working for the NHS. I have already maxed out my ISA allowance for this year, and I would like to move the rest into a SIPP.
Now, I know that as a higher rate earner, I can claim an extra 20% tax relief paying into a SIPP up to the amount I earn above the 40% tax bracket...
For some toy numbers similar to my situation, I quote an example from https://www.gov.uk/tax-on-your-private-pension/pension-tax-relief (but I increase where it said 15k to 40k, since that's closer to my situation):
You earn £60,000 in the 2024 to 2025 tax year and pay 40% tax on £10,000. You put £40,000 into a private pension. You automatically get tax relief at source on the full £40,000.
You can claim an extra 20% tax relief on £10,000 (the same amount you paid higher rate tax on) through your Self Assessment tax return.
You do not get additional relief on the remaining £30,000 you put in your pension.
So it seems to me I have two scenarios for moving this 40k into a SIPP:
A) I could move all 40k in a single go, and get the basic 20% (8k) and claim the extra 20% tax on 10k of that (2k). So in total I get 10k in tax relief.
B) I could move 10k into the SIPP each year, get the basic 20% (2k) and claim the extra 20% tax relief each time (2k), until the money is all in the SIPP. So in total I get 16k in tax relief.
It seems to me (perhaps naively?) that option B would net me an extra 6k in tax relief over 4 years? So it comes down to whether that extra 6k in tax relief would be more or less than the expected compound investment growth caused by less time in the market...
Happy to give any extra info that may be relevant! And thank you for any help you can give me!
