Under Article 3 of Kuwait Income Tax Decree No. 3 of 1955, as amended by Law No. 2 of 2008, taxable income is determined after deducting all expenses and costs incurred to realise that income. Specifically, the article permits the deduction of several key expenditures. These include salaries, wages, end-of-service indemnities, and similar allowances for employees. Also deductible are taxes and fees, excluding the income tax payable under this law. The article allows for asset depreciation, donations to licensed Kuwaiti authorities, and head office overhead, with percentages and limits for these specified by the Executive Regulations.
