What Is the General Tax Authority (GTA)? Qatar's Tax Regulator, Explained

What the GTA is

The General Tax Authority was established in 2018 under Amiri Decision No. 77 of 2018 to apply Qatar's tax laws, assess declarations, collect tax, administer double taxation agreements and pursue tax crimes. Everything it does for taxpayers runs through Dhareeba, its e-services portal, live since 1 July 2020: registration, tax cards, returns, contract declarations, payments, certificates and objections all originate there.

The substance sits in Law No. (24) of 2018, as amended by Law No. 11 of 2022, plus its Executive Regulations and a series of GTA President circulars. The circulars matter as much as the law: several thresholds exist only there.

What the GTA administers

As of August 2026 the GTA lists five taxes on its own site.

Tax	Rate	Legal basis
Income tax	10%; minimum 35% for petroleum and petrochemical agreements	Law 24/2018, Art. 9
Withholding tax	5% of gross royalties, interest, commissions and service fees to non-residents	Art. 9(2)
Capital gains tax	10% on qualifying disposals	Cabinet Resolution 3/2026 for restructuring reliefs
Excise tax	Tobacco, energy drinks, goods of special nature 100%; carbonated drinks 50%	Law 25/2018 Exec. Regs, Art. 2
Global and domestic minimum tax	Pillar Two, fiscal years from 1 January 2025	Cabinet Resolution 2/2026

Withholding tax applies to services performed wholly or partly in Qatar. From 6 July 2026 sweetened drinks moved onto a tiered volumetric excise model based on sugar content. [NEEDS SOURCE: the exact per-litre bands under that model]

On VAT, be precise. Qatar is party to the GCC Unified VAT Agreement and the GTA's laws page still carries it, but VAT is not among the taxes the GTA administers and Dhareeba has no VAT registration or return service. Treat Qatar as a pre-VAT jurisdiction. [NEEDS SOURCE: any GTA or Ministry of Finance announcement of a Qatar VAT implementation date]

Who must register

Registration is not limited to taxpaying entities. Under Article 10 and Articles 25 to 26 of the Executive Regulations, a taxpayer must register and apply for a tax card within 60 days of the earliest of: approval to carry on the activity, commercial register registration, the first day income is realised, or registration for another tax purpose. Circular No. (3) of 2020 removed the in-person step, so the card issues alongside commercial register registration at the Ministry of Commerce and Industry. Exempt Qatari and GCC-owned entities still register, hold a card and file (Circular No. (2) of 2021).

What it requires

Obligation	Deadline	Source
Register, obtain a tax card	60 days from the first triggering event	Exec. Regs Art. 25 to 26
Annual income tax return	4 months after the tax year end	Exec. Regs Art. 29
Extension request, up to 4 further months	60 days before the deadline	Exec. Regs Art. 29
Audited statements, exempt entities at capital QAR 1m or revenue QAR 5m and above	With the return	Circular 2/2021
Simplified return, exempt entities below both	With the return	Circular 2/2021
Withholding tax statement and payment	16th of the month after payment	Exec. Regs Art. 24
Capital gains return	30 days from contract or disposal	GTA taxes information
Excise return and payment	Quarterly, 15 days from period end	Excise Exec. Regs Art. 13

For the 2025 tax year the GTA extended the general deadline to 30 June 2026, announced on 22 April 2026, holding petroleum and petrochemical companies to 30 April 2026. Extensions of this kind are announced, never assumed.

What happens if you do not comply

Article 24, as amended in 2022, sets the financial penalties: QAR 500 per day for a late return, capped at QAR 180,000; 2% of the tax due per month for late payment, capped at the tax due; QAR 20,000 for failure to register; QAR 30,000 for failure to keep the required accounting records; 15% of net income for lack of substantial activity. [NEEDS SOURCE: the QAR 10,000 contract-notification penalty cited in the GTA investor guide, against the current Article 24 text]

Two consequences bite harder than the amounts. Circular No. (10) of 2019 prohibits issue or renewal of a tax card where the taxpayer owes tax differences or sanctions, unless enforcement is suspended by the Tax Appeal Committee or a court, so an unpaid daily penalty can stall a commercial register renewal. And under Article 37 the right to assess expires five years after the year the return was filed, but ten years where no return was filed. Objections run 30 days from notification (Article 17); the GTA then has 60 days to respond, silence counting as implicit rejection (Article 18).

Mainland Qatar and the QFC are different regimes

An entity licensed by the Qatar Financial Centre is not a GTA taxpayer in the ordinary sense. The QFC runs its own regime and tax department, applying 10% corporation tax on local source profits with a 0% concessionary rate for certain activities and for firms at least 90% Qatari-owned. QFC registration, returns and rulings go through QFC systems, not the mainland Dhareeba income tax service.

FAQ

Does Qatar have VAT? Not as at August 2026. Qatar is party to the GCC Unified VAT Agreement, so implementation remains possible, but the GTA has published no date and Dhareeba carries no VAT service.

Do exempt Qatari-owned companies still have to file? Yes. Circular No. (2) of 2021 confirms they file through Dhareeba, with audited financial statements above the capital and revenue thresholds and a simplified return below them.

When is the Qatar tax return due? Four months after the tax year end, so 30 April for a calendar year end. The 2025 tax year deadline was extended to 30 June 2026 for most taxpayers. Up to four further months can be requested, at least 60 days before the original deadline.

How long is a tax compliance certificate valid? Since 22 June 2025 it runs for one year rather than one month. The change-of-ownership no objection certificate runs 180 days and the commercial register cancellation certificate 90 days.

Where a system helps

For a practice the load is not knowing the rate. It is holding registration status, tax card expiry, thresholds and deadlines for every client entity in one place. That is what Daftar is built for.
