Combined marginal rates of income tax and National Insurance contributions, 2024–25

Note and source

Note: Horizontal axis shows labour cost (gross earnings + employer NICs) for employment and gross profits (earnings) for self-employment; marginal rates are expressed as a percentage of that labour cost / profit. The charts assume all income is from earnings. Employment lines assume earnings are stable throughout the year and ignore the employment allowance.
