Yes bitcoin has a tax everytime you are going to make an transcation using pear to pear or person to person as you can see every time you are going to send bitcoin the tax are input in the transaction details or every time you are going to withdraw your money or exchange it into fiat currency. Hoping that goverment will not impose taxes soon.
Well that's not truly tax. You should know that tax is something Government charge to its people in order to build public building, road, improve medical, school, education, etc. And what you have to pay when you make a transaction is called fee. Fee is different from tax.
Yeah that is not even a tax, that is what we called 'fee' for every transaction we are making and the government is not benefiting with those fees. But the miners are the ones who are getting paid for their job for confirmation of our transaction. And bitcoin will be taxed if this is going to be accepted and advertised by our local government.
