Many people think that avoiding taxes is an inappropriate criminal act, but in my opinion the tax that we pay certainly must be proportional, the facts in my country that business tax, income and so on are very burdensome so that many businesses are made to avoid taxes. And in my opinion as long as we have the right reason to avoid taxes, this is certainly not a problem.
Well, it's true that when you actually have a right reason to do something even if what you are about to do is bad, you are not wrong. So in the case of paying taxes, it totally depends on the government of the country and how the law and order of the country. If there are strict laws and government officials are not corrupt to the core and don't use tax money for personal purposes, in such a country, you shouldn't avoid paying taxes as the taxes will be used for good causes.
On the other hand, when a country is full of corrupt people, politicians are all corrupt to their core and you know that the money you are going to pay in taxes will be divided and eaten by those politicians instead of using it for the betterment and development of the country, you better not pay them.
