How much are employee pension contributions? The minimum pension contribution is 5% of your pensionable earnings between £6,240 and £50,270 p/a. It’s worth checking that we’ve got a note of your National Insurance Number. If we do, you’ll get tax relief on your contributions. These contributions, as well as employer contributions, are included in the daily or hourly rate agreed with your agency for your assignments. We recommend learning more about how your take-home pay is calculated and how these contributions fit into it. These figures are correct for the 2023/24 tax year.
