The VAT Cash Accounting Scheme can help businesses improve cash flow by allowing VAT to be accounted for when customers actually pay invoices, rather than when invoices are issued. This can be particularly beneficial for businesses that offer credit terms or experience delays in customer payments.

Under normal VAT accounting rules, VAT is payable to HMRC once an invoice has been raised, even if payment has not yet been received. Using cash accounting helps reduce the risk of businesses funding VAT liabilities from their own resources.

Businesses can normally join the scheme if their estimated VAT taxable turnover is no more than £1.35 million in the next 12 months. Once using the scheme, businesses may continue to do so until turnover exceeds £1.6 million.

However, the scheme is not available in certain situations, including when a business has outstanding VAT returns or payments, has committed a recent VAT offence or is already using the Flat Rate Scheme.

There is no formal approval process required to join. Eligible businesses can start using the scheme from the beginning of a VAT accounting period or from the date of VAT registration if newly registered.

Businesses may also leave the scheme voluntarily at the end of any VAT period and can rejoin later if the eligibility conditions continue to be met.
