If it was an option in your country, would you pay your taxes with Bitcoin?
Or would that not make any sense to you at all, especially if you hold BTC as an asset whose value you hope to see increasing over time...?
I personally pay my taxes with EUR and will probably continue to do so even if I can pay with BTC
That is not good actually if you pay taxes, here in my country every time there is a transaction that I wanna make, I only pay for the fee then that its. But in your place I think the government in your place they to implement the segwit so that if that happen everything will centralize so they can control anything in bitcoin, but for now its only a speculation and impossible to be happen. Cross fingers

What is the relationship of the government and segwit, it has no relationship at all. Even if the government will allow bitcoin to be used in paying taxes and other government services like Switzerland does it does not mean that the government will push through Segwit. If we talk about the government placing taxes in bitcoin it is already happening today already, the exchangers that we use to trade money to bitcoin and vice versa is paying taxes to the government and that is included in the fees that we give to the site.
