Which countries have the lowest corporate tax rate?

Lowest corporate tax rates

Headline corporate income tax rates among low-tax jurisdictions:

• Cayman Islands — 0%
• United Arab Emirates — 9% (on business profits above AED 1 million)
• Hungary — 9%, the lowest standard rate in the European Union
• Bulgaria — 10%
• Ireland — 12.5% on trading income
• Switzerland — roughly 11.85%–21% depending on canton

Context

These headline rates are statutory; effective rates can differ once allowances, group reliefs and incentives are applied. The UAE’s 9% rate only applies above an AED 1 million profit threshold, and large multinationals there now face a 15% domestic minimum top-up tax under the OECD Pillar 2 framework.

Ireland’s 12.5% trading rate has long anchored its position as a corporate hub, though it too applies a 15% minimum to in-scope multinationals. Within the EU, Hungary (9%) and Bulgaria (10%) offer the lowest standard rates.
