Section 13 - Time of supply of services.

Time of supply of services determines tax liability at earliest of invoice, receipt of payment, provision or recipient books.

Time of supply of services fixes tax liability at the earliest of: invoice issuance (if timely) or receipt of payment; provision of service (if invoice not timely) or receipt of payment; or the date the recipient records receipt in its books when earlier rules do not apply. Receipt of payment is the earlier of book entry or bank credit. For reverse charge supplies the earlier of recipient payment or the date immediately following sixty days from invoice applies, with fallbacks; vouchers trigger supply on issue if identifiable or on redemption otherwise; additions to value take effect when received.
