To calculate your VAT bill, you must first determine the total amount of VAT collected from customers during the VAT accounting period. This includes VAT charged at the standard, reduced, and zero rates. Next, subtract the VAT you have paid on eligible business expenses and purchases, known as input VAT. The remaining amount, called the output VAT, is what you are required to pay to HMRC.
Businesses can use different VAT accounting schemes to simplify the process of calculating their VAT bills, such as the Flat Rate Scheme or the Cash Accounting Scheme. These schemes are designed to make it easier for businesses to manage their VAT obligations and may result in reduced administrative burdens.
