Why £100,000 is a cliff edge
Above £100,000 you lose £1 of personal allowance for every £2 you earn, until it's gone at £125,140. That creates an effective Income Tax rate of 60% in that band.
The same line matters for families. If either parent's adjusted net income goes over £100,000, you can't get Tax-Free Childcare, which can be worth up to £2,000 a year for each child.
A pension contribution can bring adjusted net income back down. See what that costs on £110,000.
