Most people struggle to Remember under 50k NI is a massive jump. Roughly the marginal bands are 32%/42%/62%/45%. Add 10% if you have kids between 60k and 80k, add 9-15% over 27% if you have student loan. The 62% marginal rate at 100k is a big kicker. Basically means most people pay far higher marginal rate between 50k and 120k than above 120k.
