Investors will soon be able to plow recently realized capital gains into projects or companies based there, slowly erase the tax obligations on a portion of those gains and, more significantly, have those proceeds grow tax-free. There are almost no limits. No limits on how much you can put in, how much tax you can avoid and, for most of the country, the types of taxes you can avoid, whether federal, state or local. No limits on how long those proceeds compound tax-free. And precious few limits on what types of investments you can make."
Let's dig into this new tax law and figure out how bitcoiners with high capital gains can take advantage of this legal gift from Washington.
This has been implemented in other countries recently as well to try and stimulate new business. I think Russia, Turkey, Germany, and a handful of Latin American countries have created special economic zones so corporations can build factories on the cheap.
Key word there is corporations. I'm not sure if these tax benefits apply to individuals or limited liability companies. You'd have to dig through the law itself with a keyword search to find out for sure.
In regards to cashing out, depending on how strict the tax laws are enforced in Puerto Rico, there's a chance you can live off of those gains without declaring them as personal income. Or make a "service payment" to another entity in bitcoin (yourself)
