VAT on Advances, Deposits and the Time of Supply

Map the transaction dates

List contract, advance receipt, invoice, delivery, acceptance and final settlement dates. Apply the current tax-point rule to the actual sequence rather than automatically using the accounting revenue date.

Advance versus deposit

An amount applied against the price differs from a genuinely refundable security deposit. Contract wording, control of funds and later application matter more than the account name.

Milestones and continuous supplies

Construction, retainers, subscriptions and staged services can create multiple supply points. Align billing, work certification and VAT reporting so one milestone is neither omitted nor taxed twice.

Reconcile at completion

When the final invoice is issued, reconcile total consideration, advances already taxed, adjustments and remaining VAT. Keep a contract-level schedule.

A practical control to retain

For each major contract, keep a schedule of contract value, tax point, invoices, advances, work certificates, VAT reported and balance remaining. Reconcile customer statements and deferred revenue without assuming accounting recognition controls VAT timing. Clearly identify refundable securities and the event that converts them into consideration. Review variations and retention releases when they occur rather than waiting for final completion.

For contractors, service businesses and accountants, the sign-off should answer the guide's four core questions in writing: Tax timing is not always the final delivery date. An advance can trigger VAT consequences. Refundable deposits need factual separation. Milestone contracts need consistent invoicing. Record who checked those answers, the source date and any unresolved fact. If a later invoice, contract or Schedule amendment changes one answer, reopen the classification or return treatment instead of silently carrying the old assumption forward.
