Do the Export of Services Sales count towards my VAT registration threshold?
No (well, not usually), you do not need to add export services to business customers when computing your turnover for the mandatory VAT registration threshold (that is £85,000 for 2022-23). This is because the export of services is considered to be out of scope for VAT.
Most of the time you do not need to add VAT to your invoices for services to overseas business customers
Warning: if your customers are not businesses, it is likely you will need to charge UK VAT at the applicable rate.
Always ensure to speak to a tax professional when computing your taxable turnover and ensure you consider HMRC's place of supply rules in respect of all your export sales https://www.gov.uk/guidance/vat-how-to-work-out-your-place-of-supply-of-services
