FP - PM'd you. For others interested, the figure I've been given (2018/19) works out at about 48% of my net pay. I'll be using the new '63%' rate (see articles above) of my net wage to guess this years 'contribution' and then top-up SIPP but keeping below 40k total contributions. Not having live data for current year isn't ideal when you can't retrospectively add to your SIPP to maximise your pension (as the govt says it encourages us to do....).
