Under Article 11 of Qatar's Income Tax Law No. 24 of 2018, every taxpayer — including those who benefit from a tax exemption — must submit a tax return to the General Tax Authority (GTA) using the official prescribed form. The return must state the taxable income and the amount of tax due for the relevant tax year.
The taxable year is generally the accounting period of the business, which under Article 5 defaults to the calendar year. However, with GTA approval, a taxpayer may adopt a different accounting period. Tax returns are typically due within four months after the end of the taxable year, though you should verify the current deadline directly with the GTA or through a tax adviser, as administrative rules can specify exact dates.
Importantly, Article 14 states that the submitted tax return itself is treated as a tax assessment, meaning the tax becomes due and payable on the day you submit the return. Under Article 20, payment of the tax due must be made on the same day as the return submission. This makes timely and accurate filing critical — late or incorrect filings can trigger penalties, so engaging a local accountant well before the deadline is strongly recommended.
