Effective Tax Rate by Income Level

How your effective federal income tax rate changes as your income moves through the 2025 brackets (single filer, standard deduction).

Key findings

  • Effective rate is always lower than marginal rate. A single filer earning $100,000 has a marginal rate of 22% but an effective rate around 14.2% — because the first $11,925 is taxed at 10%, the next chunk at 12%, and only the amount above $48,475 at 22%.
  • The standard deduction lowers the starting point. In 2025, the $15,000 standard deduction for single filers means the first $15,000 of income is untaxed. Someone earning $50,000 only pays tax on $35,000.
  • Effective rates rise slowly at first, then steeply. From $50K to $100K, the effective rate rises about 6 percentage points. From $200K to $500K, it rises about 9 points — the 32% and 35% brackets accelerate the climb.
  • Even top earners don't pay 37% on everything. A filer at $1 million has an effective rate around 32.8% — well below the 37% top marginal rate. The progressive structure means every dollar is taxed at its own bracket rate, not the top rate.

Methodology

Effective rate is calculated as total tax divided by gross income. These figures use the 2025 single-filer brackets from IRS Rev. Proc. 2024-40, with the $15,000 standard deduction applied. Tax owed at each bracket boundary is computed by summing the tax in each bracket up to that point. For joint filers, the bracket thresholds roughly double, which changes the effective rate at the same gross income — use the Federal Tax Calculator for exact figures.
