The short version
- Registration and a tax invoice are necessary but not always sufficient.
- The purchase must support taxable business activity.
- Private and exempt use can restrict credit.
- Evidence should connect invoice, receipt and payment.
Apply five tests
Check supplier validity, invoice validity, actual receipt, business purpose and connection with taxable activity. Then check whether the Act or Rules specifically restrict the category. Failure at one stage can block or reduce credit.
Substance matters
A VAT invoice does not by itself prove that goods arrived or services were performed. Keep purchase orders, delivery notes, stock entries, contracts, work output and payment evidence appropriate to the transaction.
Match use to credit
Inputs used wholly for taxable supplies may qualify, while exempt, private or non-business use can deny credit. Common overhead serving both taxable and exempt activities may need a reasonable, documented apportionment.
Review before claiming
Run duplicate invoice, supplier status, date, arithmetic and business-use checks before including the credit in a return. Correct unsupported claims promptly rather than carrying an unexplained balance for years.
A practical control to retain
Use a credit checklist at invoice entry, not only when the VAT return is due. Tag the supplier verification date, receipt evidence, business purpose, taxable-use category and any restriction review. Items that fail should move to a suspense or blocked-credit queue with an owner and resolution date. This creates a transparent trail and prevents an unsupported invoice from being repeatedly reclaimed after it was rejected once.
For vat registrants, accountants and internal reviewers, the sign-off should answer the guide's four core questions in writing: Registration and a tax invoice are necessary but not always sufficient. The purchase must support taxable business activity. Private and exempt use can restrict credit. Evidence should connect invoice, receipt and payment. 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.
