Higher Rate Tax Threshold

One or both salaries cross the higher rate threshold (£50,271.00). Above this, you pay 40% tax on additional earnings, so the actual take-home difference is smaller than it appears.

  • Pension contributions above £50,271 save 40% tax - very valuable
  • Consider salary sacrifice schemes for electric cars or cycle-to-work
  • Above £60k, child benefit starts being clawed back (if applicable)
  • Equity or bonus structures may be more tax-efficient than base salary
