The reward made by the taxpayer to his employees and exceeding the limit accepted by the Authority as a limit for considering it a deductible expense does not, in essence, represent a documentary dispute related to the submission of documents proving the truth of the amounts that were disbursed as bonuses, as setting the limit for it as a deductible expense is not based on significant evidence of invalidity. Deducting what exceeds that limit as an expense may be deducted when calculating the zakat base, as long as the dispute was not in dispute over the truth of that expense.
