A tax exemption undertaking is a written commitment issued by the Governor-in-Council of the Cayman Islands, under the Tax Concessions Act, confirming that no future legislation imposing taxes on profits, income, gains, or capital appreciation will apply to the company for a specified period. For exempted companies, the undertaking is typically granted for 20 years and can be extended for a further 10 years, providing up to 30 years of statutory tax certainty.
What the undertaking covers
A tax exemption undertaking issued under the Tax Concessions Act is a binding commitment by the Cayman Islands government that no law enacted after the date of the undertaking imposing taxes on profits, income, gains, or capital appreciation shall apply to the company or its operations during the undertaking period. It also confirms that no tax in the nature of estate duty or inheritance tax shall be payable on the company’s shares or other obligations, and that no withholding tax shall apply to dividends or other distributions paid to shareholders.
Why it matters
The Cayman Islands at the time of writing (June 2026) imposes no income tax, capital gains tax, withholding tax, or corporate tax of any kind. The undertaking does not exempt the company from current taxes, since no such taxes exist, but provides a contractual and statutory assurance against any such taxes being introduced during the undertaking period. For institutional investors and fund structures with long investment horizons, this long-term certainty is a material and distinctive feature of the Cayman Islands as a domicile.
Duration: exempted companies versus limited partnerships
For exempted companies, the undertaking is granted for a period of up to 20 years from the date of approval by the Governor-in-Council, and can be extended for a further 10 years upon application, providing a maximum of 30 years of protection.
This is confirmed by PwC’s Worldwide Tax Summaries (last reviewed February 2026). For exempted limited partnerships, the Tax Concessions Act provides for a longer undertaking of up to 50 years.
How to apply
An application for a tax exemption undertaking is made through the company’s licensed registered agent in the Cayman Islands. The registered agent submits the application to the Governor-in-Council on behalf of the company. The application requires confirmation that the company is duly incorporated, in good standing, and has complied with all relevant filings, including annual returns, beneficial ownership obligations, and economic substance requirements where applicable. A government fee is payable on application, and the undertaking is issued in the form of a certificate.
Is it mandatory?
A tax exemption undertaking is not mandatory. However, it is standard practice to obtain one at or shortly after incorporation. The cost is minimal, and it is routinely requested by institutional investors, fund administrators, and tax counsel during due diligence. Obtaining it at incorporation eliminates the need to address future tax certainty questions in every subsequent investor or counterparty negotiation.
In an environment of increasing global fiscal uncertainty, the Cayman Islands tax exemption undertaking remains one of the most tangible and long-dated tax certainty commitments any jurisdiction offers to international investors, and is one of the simplest to obtain.

No. A tax exemption undertaking must be applied for separately through the company’s licensed registered agent. It is not issued automatically on incorporation, but it is standard practice to apply at the time of or shortly after incorporation given the minimal cost and the long-term certainty it provides.
Not exactly. The Cayman Islands currently (as at June 2026) imposes no taxes on income, capital gains, or corporate profits, so the undertaking does not exempt a company from any current taxes as none apply. Its purpose is to provide a binding government commitment that no such taxes will be introduced during the undertaking period, regardless of future changes in Cayman Islands legislation.
