Income tax and National Insurance are set nationally, so £100,000 in London delivers exactly the same £68,557 take-home as it would in any other English city. What changes between cities is cost of living — chiefly rent. As a Higher Rate taxpayer, pension contributions attract 40% tax relief — every £600 contributed costs you only £360 net. A pension contribution of £49,730 would drop your taxable income back to the £50,270 Basic Rate boundary, eliminating your 40% liability.
