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
