Is the income tax unconstitutional?

Some people say the income tax is unconstitutional. It was not in the original constitution, that is true. But it was put in 1913 by Congress. And the constitution does say that the congress has power to impose taxes on the population. So even though it's not explicitly in the constitution and congress has a right to raise money through taxes and therefore they have created the Internal Revenue Service and do charge taxes that is completely a legal kind of thing. A lot of people will say that they are part of some religion that doesn't believe in paying taxes or they're part of some obscure Indian tribe that's exempt from taxes. People try all kinds of things to avoid paying taxes. But all that is illegal, the tax code has been upheld by the Supreme Court many times and it is constitutional.
