Withholding Tax: The Hidden Tax Risk in Daily Business Payments

Written by: Adel Khelifi on October 23, 2026

Every month, a Tunisian company’s accounts payable department pays rents, fees, services, and contracts. In each of these payments lurks a tax obligation that is often treated as a mere administrative gesture. Yet this obligation engages the company’s financial responsibility, sometimes far beyond the initial amount.

An ancient mechanism that structures the entire system

Withholding tax has been practiced in Tunisia for more than half a century, and its financial effectiveness for the State is such that the tax system would be difficult to conceive without it. This mechanism makes every company a tax collector on behalf of the Treasury.

Salaries, fees, rents, commissions, contracts, and sums paid to non-residents are involved. The risk arises from this delegation. The company is not the taxpayer, but it becomes the debtor to the State as soon as the withholding is not carried out correctly.

When a one-day error becomes the company’s debt

The logic is harsh and constant: any failure or error in withholding places the tax on the company’s shoulders. Let’s take a simulation. A company pays 20,000 dinars in fees without withholding, while the 15% rate applied.

The evaded withholding amounts to 3,000 dinars. The company must pay them from its own funds, without being able to recover them from the service provider once full payment is made. It then incurs a penalty, detailed below.

Ordinary payments, tricky classifications
