Window Tax.

Window tax was a historical property tax imposed on the number of windows in a house and no evidence of the existence of this type of tax can be found in Doha, Qatar. This form of tax is not included in the form of modern tax in Qatar. The taxation system of Qatar is more oriented on corporate taxation and taxes called excise collected on particular goods. The authority charged with the responsibility of making sure that tax laws are administered in the country is called the General Tax Authority (GTA). Other important elements of the Qatari tax system involve a 10 percent flat tax on corporate income tax due on the taxable income of the wholly or partially foreign owned businesses. Oil and gas income is taxed under a different and high rate of tax involving a rate of 35 per cent.

also, Qatar has an excise tax which is a consumption tax on selected products believed to be harmful to the body of a human being like tobacco products and energy drinks. worth noting, Qatar does not impose personal income tax on the sectors of salaries, wages, and allowances to working people. But a self employed individual can also become payable to the income tax as he/she can get qualifying income through sources available in Qatar.
