Self-employment tax in 2024
Self-employment income carries 15.3% in SE tax on top of income tax — 12.4% Social Security and 2.9% Medicare — charged on 92.35% of net earnings. For 2024 the Social Security portion stops at $168,600.00 of earnings; the Medicare portion has no ceiling. Half of what you pay is deductible against income tax, and the calculator applies that automatically.
2024 safe harbor: what stops a penalty
You avoid an underpayment penalty for 2024 by meeting either safe harbor: 90% of your final 2024 tax, or 100% of your total 2023 tax. The prior-year figure rises to 110% if your 2023 adjusted gross income was above $150,000.00 ($75,000.00 married filing separately).
2024 estimated tax questions
- When are 2024 estimated tax payments due?
- The four 2024 installments are due Apr 15, 2024, Jun 17, 2024, Sep 16, 2024, Jan 15, 2025. A deadline that falls on a weekend or legal holiday moves to the next business day, and the dates above already account for that.
- What is the 2024 standard deduction?
- For 2024 it is $14,600.00 single, $29,200.00 married filing jointly, $14,600.00 married filing separately, $21,900.00 head of household. The calculator applies it automatically unless your itemized deductions come to more.
- How much do I need to pay to avoid a 2024 underpayment penalty?
- Meet one of the two safe harbors: pay at least 90% of your final 2024 tax, or 100% of your total 2023 tax — 110% if your 2023 adjusted gross income was over $150,000.00 ($75,000.00 if married filing separately). The calculator tests both and tells you which is cheaper.
- What is the 2024 Social Security wage base for self-employment tax?
- $168,600.00. Self-employment income above that is no longer subject to the 12.4% Social Security portion, though the 2.9% Medicare portion continues with no cap.
- Can I use the annualized income installment method for 2024?
- Yes. If your 2024 income arrives unevenly, Schedule AI of IRS Form 2210 lets you size each installment to the income you had actually earned by that point in the year, rather than paying four equal amounts. This calculator supports it in full.
