Can someone help me with my recent question please

THE QUESTION:

You have been put in charge of the taxation of the Mars colony. You need to decide how to tax the citizens of the colony.Will you institute a progressive, regressive, or a flat tax on income? Will you institute excise taxes? If yes, what goods and services will you tax and why? Will you institute sales taxes, property taxes, or VAT on goods?

Explanation:

I am not good at these terms, but

I would not use a flat tax, as I know that it would make lot's of people's life harder, from the middle class, to lower class, that might put people in financial struggles. Instead, I would charge different taxes on people, judged on their income. That would help lot's, and would be a good deed. Also, I will also use property taxes, because most of the time, if you didn't have money to spare, you wouldn't spend it on a house, right? I might have sale taxes, which I would say depends on how much I need as a government on MaRs! :|)
