Kazakhstan's tax authorities have significantly expanded reporting obligations for foreign entities operating in the country. The changes – which came into force at the start of 2025 – affect corporate income tax filings, withholding tax declarations, and disclosures tied to permanent establishment status. Foreign companies that have so far relied on simplified reporting procedures may now find themselves out of compliance.
Kazakhstan's updated tax legislation introduced mandatory enhanced reporting for foreign legal entities deriving income from Kazakhstani sources, effective from 1 January 2025. The changes impose new disclosure obligations relating to corporate income tax, withholding tax, and permanent establishment determinations. The primary compliance deadline for the first reporting period under the new rules is 31 March 2026.
This alert explains who is affected, which thresholds apply, and what immediate steps foreign entities should take to avoid penalties under Kazakhstan's tax legislation.
What changed – the regulatory development and effective date
Kazakhstan's tax legislation was amended to bring the country's reporting standards closer to international norms, including OECD-aligned disclosure requirements. The changes took effect on 1 January 2025 and apply to the 2025 tax year in full.
Three principal changes are relevant to foreign entities. First, the threshold for mandatory corporate income tax registration has been lowered. Foreign legal entities that previously fell below the registration threshold must now assess whether their Kazakhstani-source income triggers an obligation. Second, withholding tax declarations must now include more granular counterparty information. Payers of Kazakhstani-source income to non-residents are required to identify each beneficiary, the applicable tax treaty rate, and the legal basis for any exemption claimed. Third, the criteria for determining a postoyannoe uchrezhdeniye (permanent establishment) have been broadened. Preparatory and auxiliary activities that were previously excluded from the permanent establishment definition are now subject to closer scrutiny under the revised rules.
Practitioners advising foreign clients in Kazakhstan note that the revised rules reduce the practical scope of tax treaty protection unless the foreign entity can demonstrate genuine tax residency in the treaty partner jurisdiction and produce a valid tax residency certificate at the time of payment. not merely upon request during an audit.

Who is affected – threshold criteria and business categories
The new obligations apply primarily to four categories of foreign entity.
- Foreign legal entities earning income from Kazakhstani sources without a registered branch or representative office in Kazakhstan.
- Non-resident companies providing services remotely to Kazakhstani counterparties, where the engagement exceeds defined duration thresholds over a rolling 12-month period.
- Holding structures and intermediate entities receiving dividends, royalties, or interest from Kazakhstani subsidiaries or associated enterprises.
- Foreign entities that have employees or agents operating in Kazakhstan, even on a temporary or project basis, which may create a permanent establishment under the expanded criteria.
The duration threshold for service-related permanent establishment has been reduced. Foreign entities providing services – including management, consulting, and technical services – for an aggregate period that crosses the revised threshold within any 12-month window are now deemed to have a permanent establishment. This is a material change for project-based businesses.
Withholding tax obligations fall on the Kazakhstani payer, but the foreign recipient bears the risk of tax treaty benefits being denied if documentation is insufficient. Under Kazakhstan's tax legislation, a tax treaty exemption or reduced rate is only available if the foreign entity provides a valid tax residency certificate before the income is paid. Certificates produced retroactively do not automatically cure a withholding tax underpayment.
Foreign holding companies channelling income through intermediate jurisdictions face additional scrutiny. Kazakhstan's tax legislation now includes anti-avoidance provisions that look through conduit structures when the intermediate entity lacks genuine economic substance. The beneficial ownership test has been made more stringent, and tax authorities may disregard treaty benefits where the intermediate entity cannot demonstrate that it retains decision-making control over the relevant income.

What to do now – immediate actions and compliance timeline
Foreign entities with any Kazakhstani-source income or operational presence should take the following steps before the 31 March 2026 deadline for the 2025 reporting period.
- Conduct a permanent establishment review. Map all personnel, agents, and service activities in Kazakhstan against the revised permanent establishment criteria. Identify whether any combination of activities – even if individually below the threshold – cumulatively creates an exposure.
- Verify tax residency certificates. Confirm that valid tax residency certificates are on file for each payment stream attracting a tax treaty rate. Certificates must be current for the relevant tax year and issued by the competent authority of the treaty partner jurisdiction.
- Review withholding tax declarations. Ensure that all Kazakhstani counterparties who make payments to your entity are aware of their enhanced declaration obligations. Gaps in counterparty compliance can trigger joint liability risks for the foreign recipient.
- Assess beneficial ownership documentation. For holding structures, prepare substance documentation demonstrating genuine decision-making at the level of the treaty-protected entity. This includes board resolutions, management accounts, and evidence of local operational capacity.
- Register if required. Foreign entities that now meet the registration threshold under the revised rules must file for corporate income tax registration in Kazakhstan. Failure to register on time carries penalty exposure that accrues from the date the threshold was first met.
Engaging a lawyer in Kazakhstan with cross-border tax experience is strongly recommended for entities that have not previously been required to file in Kazakhstan. The revised rules are being actively enforced, and the first audit cycle under the new regime is expected to begin in the second half of 2026.
