Head of household at $100,000
An unmarried person who pays more than half the cost of a home for a qualifying child or dependent files as head of household and keeps $77,919 at $100,000 in South Carolina: wider brackets and a larger standard deduction than single, though not as wide as joint filing. Child tax credits come on top and are not part of this payroll view. State tax for head of household is modelled on the single schedule here; a few states, notably California and New York, have slightly wider head-of-household brackets, so state tax there can be modestly lower.

Frequently asked questions
Does this assume one income or two?
One salary of $100,000 for the whole household. When both spouses earn, each paycheck is taxed closer to the single schedule and the joint advantage shrinks; run each salary separately in the South Carolina calculator for a dual-income picture.
Why do married couples keep more on the same salary?
The 2026 joint standard deduction and every joint bracket are exactly twice the single amounts, so one income is spread across much wider low-rate bands. Social Security and Medicare do not change with filing status.
What assumptions does this page make?
Tax year 2026 annual view, standard deduction, no dependents or credits, no pre-tax benefits. State notes: South Carolina: Top rate scheduled to revert to 6.2% on 1 July 2026 per statute, not yet reflected. See the US methodology.
