An invoice can agree with the amount paid and still leave an input VAT claim unsupported. The finance team needs to establish what was purchased, whether it qualifies for a deduction and whether the evidence meets Zambia’s VAT requirements.
Test eligibility before checking the invoice
Start with the business and the purchase. ZRA explains that VAT-registered businesses may claim input tax on eligible goods and services acquired for making taxable supplies. If a purchase serves both taxable and exempt activities, assess whether apportionment is required. Check for any applicable deduction restrictions and confirm the period in which the claim can be made.
Section 18 of Zambia’s Value Added Tax Act governs input tax deductions and supporting evidence. Keep the eligibility decision with the evidence so a reviewer can see why the purchase qualified and how any adjustment was calculated.
Match the evidence to the transaction
For an ordinary domestic purchase requiring a tax invoice, check the supplier and buyer details, registration particulars, invoice reference and date, description, quantities, currency and VAT information. Match the invoice to the purchase order, goods received note or service acceptance record, where applicable. These records explain what the business received and how it used the purchase.
A payment confirmation shows money moved. Keep it alongside the required tax document and supporting records. For imported goods, retain the applicable customs evidence and match it to the shipment and purchase. Link credit and debit notes to the original transaction so adjustments can be traced.
Verify the claim before filing
For domestic purchases, ZRA’s Practice Note No. 1 of 2025 explains that the invoice must come from Smart Invoice or be a prescribed invoice issued by a supplier exempt from using Smart Invoice. Check that the buyer and supplier details match the transaction. ZRA’s input tax guidance gives a general 90-day limit from the date of the invoice or other qualifying evidence to submission of the return, subject to specified exceptions.
Reconcile proposed claims to the purchase ledger. Investigate missing invoices, duplicate entries and mismatches before filing. For imports, ZRA identifies the CE 20 customs form, receipt and release order as supporting evidence. Keep the reconciliation and documents together for review.
Worked example for a Zambian distributor
A VAT-registered distributor buys cartons for its taxable sales and imports a batch of stock. It also returns damaged cartons from a previous domestic order. The accounts team reviews each transaction before preparing the return.
The cartons invoice matches the receiving record, but the buyer’s details on the Smart Invoice are incorrect. The team holds the claim and asks the supplier to correct the invoice through Smart Invoice. Once the team has qualifying evidence with the correct buyer details and confirms the claim is within the permitted period, it includes the eligible input VAT in the appropriate return.
For the imported stock, the team matches the bill of entry and evidence of import VAT to the shipment and prepares the supporting schedule or evidence required for filing. For the returned cartons, it matches the supplier’s credit note to the original invoice and checks whether the original input VAT was claimed. If it was, the team records the corresponding reduction under the applicable adjustment rules.
The review separates items ready to claim from those awaiting evidence and adjustments that reduce a previous claim. Each entry in the return can be traced back to the purchase records and the decision made by the reviewer.
