No Individual Tax Filing

No personal tax return: Individuals in Kuwait do not file any personal tax return. There is no requirement to report income, assets, or gains to the tax authorities.
No registration: Individuals do not need to register with the tax authorities or obtain a tax identification number (TIN). The civil ID number serves as the identification for the administrative purposes.
No reporting obligation: Even individuals with the foreign income, the investment income, or the crypto gains have no reporting obligation in Kuwait. The tax filing requirement does not exist for the individuals.

Corporate Tax Filing — Annual Deadline

Who must file: The corporate tax filing is required for: (a) the foreign companies operating in Kuwait (including the branches and the permanent establishments); (b) the Kuwaiti companies in the oil and gas sector; (c) the Kuwaiti companies with the foreign partners (the "mixed" entities).
Filing deadline: The annual corporate tax return must be filed within 6 months after the end of the fiscal year. The fiscal year is typically the calendar year (January to December), unless otherwise approved by the tax authorities.
Return form: The tax return is filed on the prescribed form issued by the Ministry of Finance — Tax Department (إدارة الضرائب بوزارة المالية). The return includes the financial statements, the tax computation, and the supporting schedules.

Filing with the Ministry of Finance (Tax Department)

Tax Department jurisdiction: The Tax Department of the Ministry of Finance is the primary tax authority in Kuwait. The corporate tax returns are filed and processed by the Tax Department.
Submission method: The tax returns are submitted in paper form (hard copy) to the Tax Department. The electronic filing (e-filing) system is not yet available for the corporate tax returns.
Tax assessment: After filing, the Tax Department may conduct a tax audit and issue a tax assessment. The assessment can be appealed to the Tax Appeals Committee and subsequently to the courts.

KFAS and NLST Separate Filings

KFAS contribution filing: Companies registered with the Kuwait Foundation for the Advancement of Sciences (KFAS) must file an annual KFAS return with the audited financial statements, calculating the 1% contribution on the net profits.
NLST contribution: The National Labour Support Tax (NLST) — ضريبة دعم العمالة الوطنية — is a 2.5% tax on the net profits of the Kuwaiti joint stock companies (KSC). The NLST return is filed separately with the Ministry of Finance.
Filing frequency: Both the KFAS and the NLST returns are annual filings, due within the same 6-month period after the fiscal year end as the corporate tax return.

Transfer Pricing Documentation

TP requirements: Transfer pricing (TP) documentation is required for the foreign companies with the related-party transactions in Kuwait. The documentation must follow the OECD Transfer Pricing Guidelines and the arm's length principle.
Master file and local file: The TP documentation includes the master file (the group-level overview) and the local file (the Kuwait-specific transactions), along with the country-by-country (CbC) report for the groups exceeding the threshold of EUR 750 million in the consolidated revenue.
Penalties: The failure to maintain or submit the TP documentation can result in the penalties of up to 1% of the value of the related-party transactions, in addition to the potential TP adjustments.

Public Auditor Requirement

Mandatory audit: All companies filing a tax return in Kuwait must have their financial statements audited by a licensed public auditor registered with the Ministry of Commerce and Industry.
Auditor's report: The audited financial statements and the auditor's report must be attached to the tax return. The auditor must be independent and licensed to practice in Kuwait.
Auditor's tax certificate: The auditor must issue a tax certificate confirming that the tax computation is prepared in accordance with the Kuwait tax law and that the declared income is accurate.

Simplified Process for 0-Tax Companies

Zero-tax companies: The Kuwaiti-owned companies (100% Kuwaiti) that are not in the oil and gas sector and have no foreign partners pay 0% corporate tax. These companies file a nil return or a simplified declaration.
Simplified filing: The simplified filing requires: (a) the basic company information; (b) the confirmation of the 100% Kuwaiti ownership; (c) the audited financial statements; (d) the declaration of the nil tax liability.
Exemption certificate: The companies with the 0% tax rate may obtain a tax exemption certificate from the Ministry of Finance, confirming that they are not subject to the corporate tax. This certificate is useful for the banking and the contract purposes.
