OHADA-zone deductible VAT: the supporting evidence that secures your deduction

The principle: deductible upstream VAT

Under the VAT regimes applicable across OHADA states (each having its own General Tax Code), a VAT-liable taxpayer may deduct VAT paid on purchases from VAT collected on sales. The net result is remitted to the tax authority or carried as a credit.

This deductibility is not automatic. It is subject to substantive conditions (link with the taxable activity) and formal conditions (compliant supporting documents). Failing either condition triggers tax-authority rejection on audit, with recovery and penalties.

The baseline documents

The vendor's invoice must carry the mandatory mentions: full identification of both parties (corporate name, address, trade register, tax ID), invoice number and date, precise description of goods or services, unit price and quantity, ex-tax amount, VAT rate and amount, total inc-tax, specific legal mentions per regime in force.

Without the vendor's IFU or NIF, the invoice is void for VAT deductibility. It's the most common error seen by OHADA-zone external auditors.

Specific e-invoicing regimes

In Bénin the MeCEF system, and in Côte d'Ivoire the FNE, impose additional conditions. An invoice issued outside the normalised circuit no longer opens VAT deduction, even if it is otherwise compliant on mandatory mentions.

For a Bénin vendor subject to MeCEF or an Ivorian vendor subject to FNE, verifying the unique identifier or FNE QR code is a mandatory control before posting the invoice.

Common traps to avoid

First trap: invoice without IFU/NIF. Second trap: invoice billed to an entity different from the payer (intra-group invoicing). Third trap: invoice for a purchase unrelated to the taxable activity (gifts, lavish spend). Fourth trap: proforma invoice or quote presented for VAT deduction, which is not allowed.

Fifth, more subtle trap: foreign-currency invoice with incorrect conversion. The rate to use is generally the one on the transaction day, set by BCEAO or BEAC. A wrong conversion misstates deductible VAT.

Tooling the control in the procurement software

On receipt of a vendor invoice, modern procurement software automatically checks mandatory mentions, verifies the IFU/NIF against the vendor master, recomputes VAT and compares with the amount on the invoice, and blocks posting on any anomaly.

Procura ships these controls in its Comptia accounting module, turning VAT from a permanent tension with the tax authority into a defensive and automated process.
