Civil ID numbers in Kuwait are readily accessible on individual's Civil ID cards. For Kuwaiti nationals, this crucial identifier can also be located on the photo page of their passports. Additionally, Civil ID numbers are featured on Tax Certificates issued by the Tax Department for individuals.

Frequently Asked Questions
What documents does a foreign company need to register with Kuwait's Department of Income Tax, and how long does registration take?
Foreign companies must register with the Department of Income Tax (DIT) within 30 days of signing a contract in Kuwait or commencing activities — whichever is earlier. [1] The DIT registration package requires: a completed registration form, a financial-period approval request, a tax-card application, an approved-auditor form (per Article 13 of Income Tax Law No. 3 of 1955), copies of the company's memorandum of association, a commercial registration certificate, and details of any local agent and agency agreement. [2] All documents originating abroad must be translated into Arabic and undergo full embassy legalisation — Kuwait is not a signatory to the Hague Apostille Convention, so a three-step process (home-country notarisation → home Ministry of Foreign Affairs → Kuwait Embassy attestation) is required before submission. Registration is a physical in-person process at the Tax Liability and Planning Department, Ministries Complex, Al-Merqab, Block 1, Building 14, 1st floor. Companies that miss the 30-day window face penalties under the Executive Bylaws of Law No. 2 of 2008.
Why is 5% of every payment to our company being withheld by our Kuwaiti client, and how do we get it released?
Kuwait does not operate a conventional withholding tax. Instead, the Executive Bylaws of Law No. 2 of 2008 impose a 5% tax retention mechanism: every Kuwaiti public body and private entity is legally obliged to withhold 5% of each payment made to any incorporated body — foreign or domestic — until that company presents a Tax Clearance Certificate (TCC) issued by the Kuwait Tax Authority (KTA). [3] The retained amounts sit in trust for the State Treasury. To release them, the foreign contractor must: (1) register with DIT, (2) file tax returns for all periods of Kuwait activity, (3) settle any CIT assessed, and (4) apply for a TCC from the Ministry of Finance. [4] Critically, if a Kuwaiti payer fails to apply the 5% retention, the KTA disallows the entire related cost from that payer's deductible expenses — imposing an effective 15% penalty on the gross payment value. Foreign companies with short-term contracts should factor full retention-release timelines into project cash-flow planning.
Does the Kuwait DMTT replace existing CIT and Zakat for large MNE groups, or do both regimes apply simultaneously?
The Kuwait Domestic Minimum Top-up Tax (DMTT), enacted as Decree Law No. 157 of 2024 and effective for fiscal years starting 1 January 2025, is a complete substitution — not an add-on. MNE groups with consolidated global revenues of EUR 750 million or more in at least two of the four preceding fiscal years are removed entirely from the scope of: Kuwait Corporate Income Tax (Decree No. 3 of 1955), the Neutral Zone Tax (Law No. 23 of 1961), NLST (Law No. 19 of 2000), and Zakat (Law No. 46 of 2006). [5] The DMTT imposes a 15% minimum effective tax rate computed using GloBE rules. Critically, the July 2025 Executive Regulations explicitly state that existing Kuwait CIT, Zakat, and NLST payments are not accepted as "covered taxes" for DMTT credit offset — a deliberate deviation from the GloBE Model Rules. [5] All in-scope constituent entities must register via the KTA DMTT electronic portal; the initial deadline was 30 September 2025, with a KD 3,000 per-entity penalty for late registration. [6]
Our Kuwaiti KSCC was incorporated three months ago and we have not registered for Zakat — are we already non-compliant?
Yes. All publicly listed (KSC) and closed (KSCC) Kuwaiti shareholding companies must register with the Ministry of Finance and obtain a Zakat taxation card within 30 days of incorporation. [7] Missing this window means the company is in default from the 31st day onward. Zakat is assessed at 1% of net annual profit (before board remuneration and other specified deductions), and an audited declaration must be filed no later than the 15th day of the fourth month after year-end (105 days). [7] Penalties for non-payment reach KD 5,000 and/or up to 3 years' imprisonment under Law No. 46 of 2006. Companies reporting a loss are exempt from payment but must still file. Zakat registration is also separate from KFAS (1% of net profit, all Kuwaiti shareholding companies except government-owned) and NLST (2.5% of net profit, KSE-listed companies only) — those are distinct filing obligations. [8]
Can our foreign company's staff make a short site visit to Kuwait without creating a permanent establishment?
Not safely. The Kuwait Tax Authority applies an exceptionally broad PE interpretation: even short-term visits by employees or representatives can be treated as creating a taxable establishment for the foreign company — a position the KTA takes "to the widest possible interpretation in order to tax all income from Kuwait." [9] Where a PE is found, the KTA may assess tax on the full contract value including work performed outside Kuwait, not just the Kuwait-sourced portion. [9] Foreign companies should analyse applicable double tax treaties before sending any personnel to Kuwait, designate a local tax representative, and register with DIT within 30 days of contract signing regardless of whether a PE determination has been finalised. Failure to register also exposes the Kuwaiti client to the 5% retention obligation on every payment made to the foreign company. [1]
