Frequently Asked Questions: UK VAT & Cross-Border Invoicing
What is the mathematical formula to extract 20% VAT from a gross price?
To extract 20% VAT from an inclusive gross price, divide the total by 1.20 to calculate the net base, and then subtract the net from the gross. Alternatively, multiply the gross price by the fraction 1/6 (or 0.16667) to calculate the exact VAT amount immediately.
How do Pakistani IT exporters handle UK VAT when billing British clients?
Under UK VAT Notice 741A (Place of Supply of Services), business-to-business (B2B) digital services supplied by a foreign supplier to a UK business are treated as supplied where the customer belongs. The Pakistani agency issues a 0% VAT invoice with the mandatory note: "Reverse charge applies: Customer to account for VAT under Section 55A of the VAT Act 1994." The UK customer then self-accounts for output and input VAT on their VAT return.
When must a business register for VAT in the United Kingdom?
UK-established businesses must register for VAT if their rolling 12-month taxable turnover exceeds £90,000 (threshold updated by HMRC), or if they expect to exceed the threshold in the next 30 days. Non-established taxable persons (NETPs) trading in the UK have a £0 threshold and must register immediately upon making any taxable sales.
