The economy,
in human terms.
What we pay, who pays it, and where the money goes.
Filing status changes the income ranges taxed at each federal rate. In the IRS’s 2025 schedule, head-of-household brackets generally extend farther than single brackets, but a status change does not make all taxable income subject to one lower rate.
Federal income tax brackets apply to taxable income, which comes after deductions reduce income. Brackets are layered, so crossing a threshold raises the rate only on income in the higher layer.
Federal filing status affects the tax brackets applied to taxable income, along with deductions and some credits. Two households with the same income can therefore face different calculations. The relevant status depends on tax rules and circumstances; income by itself does not determine the result.
A marginal rate applies to the next taxable dollar within a bracket; an effective rate compares total tax with income. Deductions and credits can change taxable income or tax owed, so neither rate alone tells every part of a household’s tax story.
