How can you help the government better than the tax we paid dully? As a responsible citizen and obedient one, paying our taxes help the governments to raise more money and with more money, they can execute more project for people that are lacking, without these taxes been paid, we will both suffer for it because the government wouldn't be able to do much.
Furthermore, if the citizens are helping the government to put taxes together, I hope they also put it in good use and not spend it unnecessary things or loot it for their own family and encourage corruption activities.
There is one simple and quality option - not only to pay taxes (obligations of a citizen) but also to demand from the authorities to use them reasonably, not to violate the law, and to fulfill obligations to the citizens of the country.
The authorities are not mythical demigods, they are hired managers who are entrusted by the population of the country to do some work for their wages, which we all pay by taxes.
PS Unless, of course, you live in a totalitarian country or a country led by religious fanatics.
