This is a corporate-tax comparison, not a personal-income-tax list. It uses 10 verified jurisdictions selected from our existing country tax and business registry data, then re-checked against PwC's corporate-tax summaries on 2026-08-16. A zero, deferred, or territorial result is never a substitute for checking management location, permanent-establishment, withholding, VAT, and home-country rules with a qualified adviser.
Which countries have zero or low corporate tax for a business?
If you are reinvesting rather than distributing profit, Estonia and Georgia are the clearest deferral cases. If your business can meet the relevant conditions, the UAE's 0% band and qualifying-free-zone income treatment are more targeted than a blanket free-zone promise. Territorial systems can suit genuinely foreign-source business income, but they do not make local-source operations tax-free.
| Jurisdiction | Corporate treatment | How to qualify | Caveat | Source |
|---|---|---|---|---|
| Estonia | 0% on undistributed corporate profit; 22% CIT at 22/78 of a net distribution. | Use an Estonian resident company or an Estonian-registered permanent establishment and retain the profit. | The deferral ends when profit is distributed or deemed distributed. | PwC sourceVerified 2026-08-16 |
| United Arab Emirates | 0% on taxable income up to AED 375,000 and on qualifying income of a Qualifying Free Zone Person; otherwise 9%. | Keep taxable income within AED 375,000 or meet the Qualifying Free Zone Person and qualifying-income rules. | Non-qualifying income of a Qualifying Free Zone Person is taxed at 9%; free-zone registration alone is not enough. | PwC sourceVerified 2026-08-16 |
| Georgia | 15% CIT is deferred while profits are retained under Georgia’s Estonian-model regime. | Retain profits rather than distribute them. | The 15% rate applies to the grossed-up value of profit distributions and certain non-business payments. | PwC sourceVerified 2026-08-16 |
| Hong Kong | Territorial profits tax: business profits arising in or derived from Hong Kong are taxable. | Establish that the relevant profits are not Hong Kong-sourced under the territorial rules. | Foreign-sourced disposal gains and dividends can be deemed taxable under the refined FSIE regime. | PwC sourceVerified 2026-08-16 |
| Costa Rica | Territorial system: Costa Rican-source income is taxable; standard corporate income is 30%. | Keep the relevant income outside Costa Rican source rules. | Foreign-source passive income can be taxed when multinational substance requirements are not met. | PwC sourceVerified 2026-08-16 |
| Panama | Territorial system: Panamanian-source income is taxable at 25%. | Keep income outside Panama-source rules and, for covered multinational passive income, meet the economic-substance requirements. | Foreign-source passive income without required substance can be taxed at 15%. | PwC sourceVerified 2026-08-16 |
| Bahrain | No general corporate income tax on income, sales, capital gains, or estates. | Operate outside Bahrain’s oil, gas, extraction, and refining exception. | Oil and gas businesses can face 46% tax; the domestic minimum top-up tax applies to covered large multinational groups. | PwC sourceVerified 2026-08-16 |
| Hungary | 9% flat CIT on the positive corporate tax base. | Use a Hungarian company or branch subject to the corporate-tax rules. | The tax base adjusts accounting profit and minimum-tax-base rules can apply. | PwC sourceVerified 2026-08-16 |
| Bulgaria | 10% flat corporate income tax. | Use a Bulgarian company or a taxable Bulgarian permanent establishment. | Bulgarian tax residents are taxed on worldwide income; Pillar Two rules can affect covered groups. | PwC sourceVerified 2026-08-16 |
| Singapore | 17% flat corporate income tax, with partial and qualifying three-year start-up exemptions. | Meet the conditions for the partial or qualifying start-up exemption. | The start-up exemption does not apply to property-development and investment-holding companies. | PwC sourceVerified 2026-08-16 |
Which structure fits your stage?
Bootstrapper verdict
Choose Estonia or Georgia if you plan to reinvest profit and can run a real operating company under their rules. Do not choose either merely for a mailing address: the useful feature is deferral while profit stays in the company, not a tax-free dividend.
VC-track verdict
Choose a conventional investor-ready structure first, then assess the UAE, Singapore, Hong Kong, or another operating location against where management and customers actually are. A headline rate does not solve investor, substance, or cross-border tax-residence requirements.
Solo-consultant verdict
Choose a territorial system only when the source of your work and the place you manage it can genuinely support that treatment. Panama, Costa Rica, and Hong Kong all show why “foreign income” needs a source and substance analysis before you invoice through a company there.
