Filing Status and Dependents

Filing status and dependent rules shape the return before most line-by-line calculation work even begins. They affect which rate schedule applies, which Standard Deduction framework the return starts from, and which household-based credits may be available later.

This section is built to help readers answer the practical question first: which household label belongs on the return, and how do dependent facts change that answer?
