Step-by-step explanation:
The income tax system in the United States offers several filing statuses to taxpayers. There are five main filing statuses: single, married filing jointly, married filing separately, head of household, and qualifying widow/widower. These filing statuses determine how much tax a taxpayer is required to pay based on their income, marital status, and other factors. For example, a single taxpayer may have different tax obligations compared to a taxpayer who is married and filing jointly.
