Why £19?

Some high-volume tax-refund agents charge a percentage of any refund they recover, often between 25% and 50%, which can run into hundreds of pounds.[1] The PayslipIQ Pro Report is a flat £19 because we do not take a cut of your refund: you keep 100%. We are a tool, not a tax agent and not a regulated tax adviser.

You also do not need a paid agent to claim a refund: HMRC will pay any genuine refund directly through your personal tax account at gov.uk/personal-tax-account or by phone on 0300 200 3300, free of charge.
