salary contributions before tax

A more detailed explanation of why pension additions are tax efficient.  To do this we'll look at an example.

If you earn £40,000 a year, and live in England,  you would expect to pay:
  • £5,484.20 in Income Tax.
  • £3,291.60 in National Insurance.
Your take-home pay is £31,224.20 (not including other deductions or allowances).

If you decided to contribute £2,000 to your pension, you would expect to pay:
  • £5,084.20 in Income Tax (you are paying £400 less because the £2,000 isn't taxed).
  • £3,291.60 in National Insurance (pension contributions still have National Insurance contributions).
Your take-home pay is £29,624.20 (not including other deductions or allowances).  However, you have also contributed £2,000 to your pension so with your take-home pay and pension contribution you have gained £31,624.20, so you are £400 better off.
