Quarterly VAT & WHT checklist
- Reconcile VAT collected vs VAT paid in the period.
- Validate every supplier's TIN — payments to suppliers without TIN attract higher WHT.
- Confirm WHT certificates are issued on time.
- Cross-check the VAT declaration with your general ledger.
- Archive supporting invoices in a way that survives an audit.
Run this every quarter and audits become routine.
