Final answer:
The pay-as-you-go feature of the Federal income tax on individuals does not conform to Adam Smith's canon of convenience.
Step-by-step explanation:
The pay-as-you-go feature of the Federal income tax on individuals does not conform to Adam Smith's canon of convenience. According to Adam Smith's canon, taxes should be equitable, simple, and efficient. The pay-as-you-go feature, where taxes are withheld from a person's paycheck and sent directly to the Internal Revenue Service, may be efficient in terms of convenience and ease but may not necessarily be equitable or simple.
