the government is going to take his taxes even with force, it doesn't matter what currency you are using for your business. as long as you are running a business in a country you have to abide by law, you can't just say i stop paying taxes because i am using bitcoin!
I totally agree. The idea of tax free bitcoin is completely false.
I am not aware of any law on the planet that allows for a loophole when using crypto-currency. The tools which will allow anyone to audit the blockchain are soon to be usable by governments around the world. They will simply throw you in jail for not paying. Asking if bitcoins are taxable is exactly the same question as "Is money taxable"? Yes, yes it most certainly is.
You will be greatly disappointed. There is no such law, but if Bitcoin itself is not allowed (or recognized as an asset), you can't possibly impose taxes on the income obtained from using it, since any operation with it will be considered as illegal. You simply can't levy taxes on something illegal, since that would instantly make it legitimate. For example, you can't collect taxes from income earned by drug trafficking or child pornography. But if it is not banned either, you essentially get your "loophole"...
And I'm not just theorizing about what
might happen, since this is exactly the case with Bitcoin in Russia, as I have already said
