Are there any countries that don't have taxes?

That would be a strange situation to imagine, like a world with cars but no traffic laws, a world with computers but no programming, or a world with love but no emotions.  Humans usually organize their societies into large-scale entities, and these entities usually require taxes in order to function well.

Which tax do you mean?  Do you mean there aren’t any income or sales taxes?  I think most countries have some sort of tax.  Do you mean you want to travel to a tax-free country for your own taxes?  The US has such an option with the IRS, which means you can make voluntary tax payments to get a refund.  It’s been the most popular type of program that helps Americans legally avoid paying taxes, in part because it’s really easy to use.  
Can I ask why you’re asking this?  Is there something in particular you’re trying to accomplish?
