What is the current UK VAT registration threshold?
£90,000 of UK-taxable turnover in any rolling 12-month period. Once you exceed it — or reasonably expect to — you must register within 30 days. Non-UK-established businesses that make any taxable supplies in the UK must register from their first sale.
Should I register voluntarily below the threshold?
Sometimes. Voluntary registration lets you reclaim input VAT on purchases and can lend credibility to B2B invoicing. But it adds compliance and can make you less competitive with consumer-facing clients. Read our full guide before deciding.
