Yes. If you carry out a business activity in Qatar or derive taxable income from sources within the country, Article 10 of Law No. 24 of 2018 requires you to register with the General Tax Authority (GTA). This obligation applies regardless of your nationality or residency status — it covers any taxpayer conducting an activity in Qatar.
Beyond initial registration, Article 10 also requires you to notify the Authority of any change that may affect your tax status. This means that if your business structure, ownership, or income sources change, you must inform the GTA promptly to remain compliant.
Practically speaking, if you are an expat who owns a company, operates a sole establishment, or is a partner in a business registered in Qatar, you should register with the GTA as early as possible. Failure to comply can expose you to penalties. The GTA provides registration services and guidance — it is advisable to work with a local accountant or tax consultant familiar with Qatari tax regulations to ensure your registration is completed correctly.
