I’d like to start taking monthly income from a SIPP but also have the possibility of some work via a Brolly.

Obviously, taking monthly income from the SIPP reduces the MPAA to £10k. But – at least this side of the budget – we know that Brolly income is best served with a large helping of salary sacrifice to pension.

I’m analysing the options under two scenarios (and have ignored brolly margin since it’s the same in both cases).

(Annual) Minimum Wage Basis Pension limit set to £10k
Fee Income £30,000 £30,000
Apprentice Levy £31 £88
Employer NI £173 £1905
Employee NI Nil £410
Gross Salary £6,175 £17,706
Pension £23,338 £10,000
Pension Input Charge £5,335 (40%) nil
Tax on Brolly Income £2,463 (40%) £7,082 (40%)
Total Tax £8,002 £9,487

Does this look correct – have I got it right that the charge for exceeding pension input amount is simply ‘contribution exceeding £10k’ multiplied by ‘marginal tax rate’?

The other issue of course is that there’s tax when removing the funds from pension later, but 25% of that becomes tax exempt.

There’s also the option of reducing SIPP income so that the marginal tax rate is 20% but this only changes the tax difference from £1484 to £1824 so there’s not much in this overall.

The only other thing I can think of is that the reduced MPAA only kicks in once the SIPP income starts, so leaving taking this until later in the tax year could be a good call.

Any thoughts?
