Assumptions

  • Relief at source: you pay 80% of the gross contribution, basic-rate relief is added to the pot, and extra higher-rate relief reduces tax without being added again.
  • The annual allowance is shown as context. Carry forward and the money purchase annual allowance are not calculated.
  • Annual allowance taper is not applied here. If your income is near the taper, check the pension annual allowance rules before relying on the contribution.

Questions

Why can the pot and the tax relief differ by method?

Sacrifice and net pay give relief by reducing taxable pay. Relief at source puts basic-rate relief in the pot and gives further relief through the tax calculation.
