Effective Rate by Income Level: A Reference Table

Single filer, 2026, standard deduction. The combined column adds Social Security and Medicare. State income tax comes on top; section 4 explains how to add it.

§ 1

The shape of the curve

Steep climb from $20K to $70K. Gradual climb from $70K to $200K. Slow grade above.

The effective federal income tax rate rises steeply between $20,000 and $70,000 (from 1.9 percent to 9.4), then more gradually from $70,000 through $200,000, and slowly above. This shape comes from two compounding effects: the standard deduction is proportionally large at low incomes and small at high incomes, and the bracket steps grow taller as income rises. FICA is flat at 7.65 percent up to the Social Security wage base, then drops sharply because the Social Security portion stops collecting.

2026 standard deduction $16,100 single (IRS Revenue Procedure 2025-32). FICA = SS 6.2% (cap $184,500) + Medicare 1.45% + Additional Medicare 0.9% above $200,000. No state tax.

§ 3Filing Status Comparison

Married filing jointly roughly doubles the standard deduction and most of the bracket widths. A couple earning a combined $150,000 has an effective federal rate near 10.2 percent, while a single filer at $150,000 sits at 16.5. The six-point gap is the structural advantage of marriage in the tax code at this income, primarily from the wider 10 percent and 12 percent brackets.

Head of household sits between the two. The standard deduction is $24,150 in 2026, and the 10 and 12 percent brackets are wider than the single filer's (they run to $17,700 and $67,450); from the 22 percent bracket up, the thresholds are at or near the single filer's. A head of household earner at $75,000 has an effective federal rate of roughly 7.7 percent, compared to 10.2 for a single filer at the same income.

The marriage penalty in the 2026 brackets is narrow. Every joint threshold up to the 35 percent bracket is exactly double the single threshold, and so is the standard deduction, so two equal earners pay the same income tax married as single until their combined taxable income passes $768,700. That is where the joint 37 percent bracket starts, well short of double the single filer's $640,600. For one-earner couples and couples with unequal incomes, joint filing usually lowers the bill.

§ 4State Income Tax Comes on Top

Every rate on this page is federal. State income tax is charged on top, and the spread between states is wide. Texas, Florida, Tennessee and a handful of others tax no wage income, so a Texas earner's combined rate is the federal-plus-FICA figure in the table above. Illinois taxes income at a flat 4.95 percent after a personal exemption (Illinois Department of Revenue, 2026 withholding tables, IL-700-T).

California and New York tax income on graduated schedules with their own standard deductions, so a single headline rate misleads. Work your state figure from the California Franchise Tax Board 2026 rate schedules or the New York State tax tables, then add it to the federal-plus-FICA rate here.
