Paying your taxes is considered a civic duty, although doing so is also a requirement of the law. If you do not pay your taxes, the government agency that oversees taxes the Internal Revenue Service or IRS will require you to pay your taxes or else face penalties, such as fines or going to jail. We must obey the regulations in our government to prevent penalties.
I know for most government workers in my country anyway, tax is being deducted from their pay anytime, which makes them automatically subjected, however, for business people, tax law is there and you are to stick by it, but the law is not strict and the targets are usually the big companies who evade tax anyway.
Nevertheless, if I am even seeing the usefulness of the tax they have been collecting, I would have at least been a good citizen being an entrepreneur, but I do not care. They are just some bunch of thieves, why give them the little that I have left ?
