UK Income Tax Bands 2026-27
The UK income tax system uses progressive bands — you only pay the higher rate on income above each threshold, not on your entire income. Understanding this eliminates the common misconception that earning slightly more pushes all your income into a higher bracket. Use our tax calculator (switch to GBP) to see your exact tax and take-home pay.
On a GBP 60,000 salary: you pay 0 percent on the first GBP 12,570, 20 percent on GBP 12,571 to 50,270, and 40 percent only on GBP 50,271 to 60,000. Total tax: GBP 11,372 plus approximately GBP 3,804 National Insurance. Take-home: roughly GBP 44,824 per year.
The GBP 100K Tax Trap and How to Escape It
The personal allowance of GBP 12,570 is withdrawn at GBP 1 for every GBP 2 earned above GBP 100,000. Between GBP 100,000 and 125,140, your effective marginal rate is 60 percent (40 percent income tax plus 20 percent from lost personal allowance). The solution: make pension contributions to bring your adjusted net income below GBP 100,000. A GBP 10,000 pension contribution at this level saves GBP 6,000 in tax — an immediate 60 percent return.
Tax-Free Income Strategies
Maximise your ISA allowance (GBP 20,000 per year, all returns tax-free). Use salary sacrifice for pension contributions (saves income tax AND National Insurance). Claim the marriage allowance if one partner earns under GBP 12,570 (worth GBP 252 per year). If working from home, claim the flat rate allowance of GBP 6 per week (GBP 312 per year).
