Repeal the ratification of the 16th amendment, imposed in 1913, allowing congress to levy federal taxation on individual(s) income.
It is unconstitutional for Individual(s) to be taxed on monies received for trading, at equal value, skill, time and physical labor, as no income and/or profit is made from an equivalent trade of resources.
The value of an individual(s) skill, time and physical labor can not be monetarily measured, as there is no income and/or profit made from an equal trade of services or goods. Income and/or profit can only be made when a monetary gain can be measured against the original investment, ie., company sells a product or service for more than what the initial investment/costs for the company to retain such good or service. Thus creating a measurable income and/or profit.
