VAT registration threshold: Currently £90,000 taxable turnover in a 12-month rolling period triggers mandatory registration.

Registration deadline: You have 30 days from the end of the month you exceed the threshold to register with HMRC.

Voluntary registration: Available if turnover is below £90,000, useful for reclaiming VAT on startup costs or improving credibility.

VAT schemes: Options include Standard VAT, Flat Rate Scheme (simpler accounting), and Cash Accounting Scheme for better cash flow.

Accounting method: Choose between cash accounting or invoice accounting based on your business model and preferences.

Online registration process: Use HMRC's online service with your Government Gateway ID; it typically takes about 2 weeks to complete.

VAT number: Upon registration, you'll receive a unique VAT number to include on all invoices and official documents.

VAT returns: Submit quarterly or monthly returns online, detailing VAT charged on sales and VAT paid on purchases.

Making Tax Digital (MTD): VAT-registered businesses must use MTD-compatible software for returns, as per HMRC requirements.

Record-keeping: Maintain detailed records of all sales, purchases, and VAT transactions for at least six years for compliance.
