How many days does a business have to inform HMRC after reaching the VAT registration threshold?

A business is required to inform HMRC within 30 days after its taxable turnover exceeds the VAT registration threshold. This timeline is crucial because it ensures that the business can comply with tax obligations and avoid any penalties for late registration. Timely notification allows HMRC to update records and ensures that the business is charged VAT correctly moving forward.

The requirement to notify within this specific period underlines the importance of proactive tax management for businesses, as exceeding the VAT threshold triggers additional responsibilities, such as the need to charge VAT on sales and file VAT returns.
