Every year HMRC conduct a tax reconciliation process for taxpayers who are mainly taxed under PAYE. If a refund is due, or more tax is payable, this is reported on Form P800.
This year, refunds won’t be automatically dispatched as a cheque. Instead the P800 will ask you either to sign into your Personal Tax Account and submit your bank details online or to ring HMRC. The refund will then be made by bank transfer.
If you take no action for 45 days, your refund will be issued by cheque. If we are authorised to receive the tax refund on your behalf, you won’t be able to use the online tax refund service.
