In itself, the taxation is not theft, but the officials dispose of the taxes it's definitely theft. If the money is not stolen it would be possible to reduce the percentage of taxation.
Here in my place, what the government officials are doing is stealing the taxes that the people pay and then, they use it to themselves or the people to make them look good or very kind who is in the position, they use taxes to make the people believe that they are really good and kind but they are not. Taxation is the most corrupted money in the government.
