Well, here in Brazil you pay taxes even for breathing, but for example, here with my salary, I pay rent and food, and for everything else here, in your annual tax return, you deduct your expenses for doctors, physical therapists, psychologists, etc.

Since the company gives you a tax discount when you declare them, and you add up your previous expenses, they give you money back. So I've been declaring them these last two years and they give me a portion of the money back, haha. Even if it's a little, it's extra money coming in.

Here in Brazil, you pay a tax called IPTU, which applies if you own land, a house, or an apartment; you can't escape that.

On the other hand, if you have a new car or one less than 20 years old, you pay another tax called IPVA, which you can only escape if you have a car that's over 20 years old.

Otherwise, the idea is, as mentioned above, to live as "legally" as possible. I bought some stocks and real estate funds, received my dividends, and declared them on my taxes. I also bought Bitcoin via P2P. There are some apps that help you spend those BTC if you want.

In addition to that, it would be good to get a second citizenship in another country. Perhaps you have an Italian or Spanish grandparent there, etc. Or, if you live in the US, find a country where you can easily obtain residency.
