Belize
You might be interested in Belize since it offers the Qualified Retired Persons Programme, which enables eligible people to live in Belize tax-free. Naturally, you will have up to 50% more to play with without the erosion of taxing on your money!
You are eligible to join the program if you are 45 years of age or older and make a minimum of $2,000 per month. Your application can also list your spouse and any dependents you have. The program's drawback is that the time spent in the nation as a Qualified Retired Person will not contribute toward the time needed to submit an application for permanent residency. Additionally, you are not allowed to look for work, but investing in businesses is strongly advised.
The benefit of this scheme is that retirees can import their personal belongings duty-free in addition to living tax-free. Belize is well protected internationally, this time by the UK, like Panama is. British visitors are welcomed in Belize, where English is the official business language. You will see how far your tax-free money may take you if you leave the busiest tourist attractions and the most populated places.
