Businesses that are registered for UK VAT but do not have a business address in the UK (known as NETPs) and are due a VAT repayment, automatically receive a payable order from HMRC in respect of the refund. However, the impact of Brexit and COVID-19 has resulted in an increase in banks and countries no longer accepting payable orders.
To address this issue HMRC are now making available the option for NETPs to request repayments by bank transfer.
