UK Tax Burden by Salary 2026/27

The detail

People conflate marginal tax rates (the rate on your last pound) with effective rates (total tax ÷ total gross). The UK headline marginal rates are 20%/40%/45% for Income Tax plus 8%/2% NI. But because the £12,570 Personal Allowance is tax-free, the effective rate is always lower than the marginal — except in the £100k–£125,140 PA-taper band, where it spikes to 60%.

At £30,000 (below the higher-rate threshold), effective = ~18%. At £60,000 you're partly in the 40% band, effective rises to ~28%. At £100,000 you hit the taper (60% marginal on the next £25,140), effective = ~32%. At £150,000 (fully taper-complete, 45% additional rate), effective = ~38%.

These figures use our salary calculator with standard PA and no pension — the actual tax burden can be reduced by pension contributions (up to 42% relief at higher rate, 47% at additional), Gift Aid, and ISA-wrapped investment income.

Note: these are England/Wales/NI figures. Scottish rates diverge above £27,491 (intermediate 21%, advanced 45%, top 48%) — Scottish high earners face higher effective rates than rUK counterparts.
