Yes, it's a new revolution in the taxing business and soon, if this is attracting more people to use bitcoin, the other company will join and will use bitcoin too. Besides that, it is a good start for bitcoin especially that the company is in the US because the US is one of the giant country and maybe the other big country will do the same. And soon, the other business section will give time to research using bitcoin as the payment system (or they already had this). It is good news for people who have bitcoin so they can use bitcoin to pay the tax and they can save their money for another thing.
It is great but I wonder why would a company buy bitcoin and pay their taxes with it if their businesses have nothing to do with cryptocurrency? Bitcoin price is very unstable and very volatile, will it be preferable for them to buy bitcoin and pay their taxes with it or just pay the government with the money they have from their businesses. If it is me, why would I spend my bitcoin if I ever have in taxes, or why would I buy bitcoin to pay tax, what if bitcoin price suddenly rises or fall, will it still be better? I would rather safely hold my bitcoin instead of giving it to the government for my tax.
