I pay my taxes, not because I want to but because the state has right to licit first use of force and can throw me in jail if I don't. I personally have too much to lose so I comply. There's nothing moral about paying taxes because there is no consent involved. I'm not paying for things I'm using. I'm having money taken from me with no guarantee that I get something in return comensurate with how much is being taken from me with the threat of violence.
That being said, I'm not going to take exception with the people who are economically at the bottom and whose lives would be far worse if they didn't do what they can to avoid having their pockets picked by government. I wish my pockets weren't being picked but if someone else is able to avoid that fate, good for them.
It's far more moral for these people to keep the fruits of their own labor to make ends meet than for them to steal from other productive citizens trying to make a living, which is what we'd be forcing them to do if there was no way for them to avoid having their pockets picked by the government.
