1. vehicle tax
Obliged to pay once a year, but there are also those who do not pay and the authorities also do not come to the taxpayer's house and in the end it is left abandoned
Impossible, when someone want to bought a vehicle he need to give his identity and it will recorded if he has a vehicle. So after a year, the tax employee can just contact him through his phone number or come into his house.
No. If they do not report their taxes, they are breaking the law. If it were as you say, no self-employed person would declare them.
You don't have to swear. Maybe you should tell us where you live to see if we can clarify.
No, they're not entirely breaking the law if they didn't self reporting their jobs and earning to the tax department, except they're have an intention to escape from tax and create fake story. A self employed person is submitting his identity on the freelance website, so the site already collected all of his identity and how much he make for every day/month/year. I believe the site is working together with the government.
If the bank account of those self employed person receive the money which exceed from the minimum income should be taxed, of course the bank will ask him where he get the money and he should report it to the tax department.
