Unfortunately, this nation taxes worldwide income. This, of course, is most undesirable for retirees since their income is offshore derived and not taxed by many more favourable countries to retire in. Brazil also has state and city taxation. There is also VAT which runs between 18% and 25% which is going to make that TV or refrigerator very expensive. What you should be looking for is a country like Panama that does not tax offshore derived income at all. This means your retirement cheques are not taxed and there is only a 5% sales tax, no VAT plus capital gains are not taxed.

In Brazil corporate taxes run about 34% with all of them combined. Personal income tax runs up to about 27% in steps. They have inheritance taxes. Brazil is in 25 tax treaties. Most of you will be discouraged at this point and rightly so. On the other side Brazil is a large highly advanced country. Some parts are full of crime, others not so crime ridden. Cost of living is going to vary.

Portuguese is the spoken language. Brazil is a Mercosur country so all the Mercosur advantages are in place. You should plan on dealing with a large bureaucratic government probably not very much unlike the country you are moving away from. Residency is not that hard to obtain but of course you can plan on giving them a lot of your money in various taxes. Real estate prices will be all over the charts due to the various cities and regions. Unless there are extenuating circumstances most of you will skip Brazil.
