United States vs Marshall Islands

Federal corporate income tax: 21%. State CIT generally ranges from 1% to 10% (although some states do not impose CIT) and is deductible for federal CIT purposes.

Within 10,000 US dollars, a corporate income tax of 80 US dollars is collected. Any excess amount is subject to a 3% tax. However, Non-resident companies not conducting business within the Marshall Islands are exempt from corporate income tax. This makes the jurisdiction attractive for offshore business activities as they do not have to pay taxes on income earned outside the Marshall Islands​​​. https://internationalwealth.info/en/offshore-taxes/everything-you-need-to-know-about-the-tax-system-in-the-marshall-islands/
