By November 2025, the Central Bank of Libya had financed roughly $14 billion in documentary credits. The original analysis asked a second question after the dollars were allocated: what should an import economy of that scale have generated in taxable profit?

The calculation translated $14 billion at an assumed effective funding rate of 6.4 dinars to the dollar, producing a dinar cost base of approximately LYD 89.6 billion.

Applying a deliberately simple 20% commercial mark-up placed estimated sales at LYD 107.52 billion and the implied gross margin at LYD 17.92 billion.

LYD 2.6bn

was the modelled gap between a theoretical tax yield and the state’s recorded tax revenue through November.

The calculation, line by line

At a 20% corporate income-tax rate, the assumed margin would imply LYD 3.584 billion in tax. The November statement recorded approximately LYD 1 billion in total tax revenue. The difference was LYD 2.584 billion, rounded in the original headline to LYD 2.6 billion.

This was a public-finance stress test, not a tax audit. It showed the scale of the reconciliation authorities should be able to perform across foreign-currency allocations, customs declarations, company accounts and tax receipts.

What the scenario cannot prove

A mark-up is not taxable profit. Importers incur freight, insurance, duties, banking charges, salaries, storage and distribution costs. Different goods carry different margins, and tax collection can lag the underlying trade.

The figure therefore cannot establish evasion or identify an offender. It is a diagnostic question built from explicit assumptions.

A dated snapshot, not a timeless total

The analysis was based on information available through 30 November. The later full-year statement recorded LYD 2.8 billion in 2025 tax revenue. That later figure belongs to a different reporting cut-off; it should be shown as an update, not used to rewrite what the November snapshot measured.

A complete answer requires linked records for each executed credit, customs arrival, declared sales, taxable profit and tax paid.

Gross margin is not the corporate tax base

The original model deliberately applies one 20% mark-up to the dinar cost of all credits. That creates a transparent benchmark, but it collapses wholesale, retail and industrial inputs into one margin and assumes the entire financed value becomes sales within the same reporting window. Imports still in transit or inventory do not generate the same-period taxable result.

Corporate income tax is levied on net taxable income after allowable expenses and adjustments, not on gross mark-up. Turnover taxes, customs duties, wage taxes and taxes paid by sectors outside importing also sit inside the state’s total tax line. The comparison is therefore a reconciliation alarm, not an estimate of an unpaid assessment.

A better sensitivity range

A stronger model would show several gross-margin scenarios—5%, 10%, 20% and 30%—then deduct documented sector costs before applying the tax rate. It would separate food staples, medicine, machinery, consumer goods and industrial inputs because their margins, inventory cycles and exemptions differ materially.

The result should also be aligned by tax year. Credits approved late in 2025 may produce sales or tax in 2026; accumulated losses and instalment schedules may defer payment. Showing these timing effects would make the benchmark more demanding and more defensible at the same time.

The reconciliation institutions should run

Each executed credit already produces records in several institutions: the commercial bank, Central Bank, customs authority, commercial registry and tax authority. A stable transaction identifier would allow them to test whether value and quantity arrived, which company booked the inventory, how it was sold and what taxable result was declared.

Risk scoring could then focus on cases with large official-dollar access but no customs arrival, implausible unit values, repeated losses, negligible sales, inactive tax files or networks of related companies. Such indicators would trigger review; they would not become automatic findings of evasion.

Publish the denominator, not only the revenue

A tax-revenue headline is impossible to interpret without the underlying tax base. Authorities should publish active corporate taxpayers, declarations filed, assessed profit, losses carried forward, arrears, collections by tax type and sector, and the share attributable to importers financed through official foreign exchange.

That disclosure would show whether the apparent gap reflects weak compliance, legal deductions, collection delay, a narrow base or a modelling assumption. It would also let later annual data update the result without erasing what the November 2025 snapshot actually measured.
