2024 Standard Deductions
Single filers: $14,600. Married Filing Jointly: $29,200. Head of Household: $21,900. These amounts reduce your taxable income before brackets are applied.
Effective vs. Marginal Rate
Your marginal rate is the rate applied to your last dollar of income. Your effective rate is your total tax divided by your total income — it is always lower than your marginal rate.
