Taking off the other person @tonytins
If we had a flat tax that would work for reported income. But there’s unreported/underreported income, deductions, weird tax situations. Which is why there are many many confusing forms.
@tonytins sales taxes, excise taxes, and property taxes (consumption taxes) are considered to be regressive taxes which means they have greater impact on lower-income.
Income tax is progressive, and ideally should be taxed at a rate higher if the person is a high earner. This helps create an equitable distribution on the tax burden.
Income taxes are typically spent on specific government services, typically on the federal level.
Fees for tax preparation may be deductible.
