Tax, VAT & MTD

What has to be reported, when, and what Making Tax Digital changes.

These answers provide general information, not advice tailored to your circumstances. Rules can change and exceptions may apply — speak to the CASS team before making a tax, accounting or financial decision.

If you are VAT registered and the deposit is an advance payment for a taxable supply, VAT normally becomes due when you receive it or issue a VAT invoice, whichever happens first. A genuinely refundable security deposit can be different. The underlying supply and your VAT scheme also matter. CASS can check the arrangement so the deposit is recorded in the correct VAT period.
