Where tax has been overpaid it can be reclaimed at the end of the tax year OR during a tax year if you are leaving the UK before the end of the tax year. You can claim back as far as six tax years. Tax years end on 5 April.

MainPay cannot give you tax advice or claim tax refunds on your behalf. However, we can offer a few guidelines on this process. You may either wish to use the services of a Tax Refund Agency or apply directly to HMRC for your refund.

Tax Refund Agencies will charge anywhere between 5% and 18% of your refund for completing a few forms. However, you are able to lodge a refund application for free yourself by calling HMRC or following the instructions on their website:


You can find all HMRC contact information for queries below:


Please note that MainPay will send you a P60 at the end of the tax year if you are still employed with us, or a P45 when your employment ceases. These are official tax documents and if any P45's or P60's are lost, they cannot be reissued. However you can find a Statement of Earnings, a sufficient replacement document, on your Financial Position page after logging in to your online personal MainPay account.
