No VAT line, gross equals net

Surveyors moving to Qatar from a VAT or GST jurisdiction reach for the tax line out of habit. There is not one. Qatar does not levy VAT on construction, so the value of work certified in the Interim Payment Certificate is the value payable. Gross equals net. It is a genuine simplification, and understanding what it removes helps you see what it does not.

What the missing tax line takes away

In a VAT regime every certificate carries an arithmetic layer: net measure, tax at the prevailing rate, gross total, with the tax point and the invoice mechanics to manage alongside the payment dates. Errors creep in at the gross-up, reconciliations have to prove the tax fraction as well as the measure, and the final account has to tie the cumulative tax as well as the cumulative value.

None of that exists here. The IPC runs on a single figure: work properly executed to date, plus Variations valued under Clause 13, less retention, less the previous certificates. There is no tax fraction to check and no tax reconciliation to carry. The certificate is shorter and the audit is cleaner.

What still moves the figure

Gross equalling net does not mean the certificate is only a measure. The FIDIC deductions and additions still apply, and they are where attention should go now that tax is not competing for it.

• Retention. Deducted under Sub-Clause 14.3 at the contract percentage, released in two halves under 14.9. This is the deduction that most affects the payable figure.
• Advance payment. Where the contract provides an advance payment, it is repaid by deductions from the certificates on the agreed schedule. That repayment reduces the payable sum and has to be tracked against the balance outstanding.
• Amounts previously certified. The gross-to-date figure less everything certified before, which governs what is actually due this cycle.

Subcontractor payments

The same simplicity flows down. A subcontractor account under a Qatar FIDIC job carries no VAT either, so the main contractor certifying down the chain values the subcontractor work net, with the subcontractor retention and any set-off, and pays that figure. The absence of tax removes the reconciliation between the main certificate tax and the subcontractor tax that a VAT regime forces on the payment run.

Use the room it frees

The practical takeaway is not that the certificate is easy. It is that the effort you would spend on tax can go into the measure, the Variations and the retention, which are the parts that decide the number. On a Qatar FIDIC job the payable figure is the valuation, so the valuation is where the discipline belongs.
