Understanding 1099 Income and Self-Employment Taxes
As an independent contractor receiving income reported on Form 1099-NEC (Nonemployee Compensation) or 1099-MISC, you are considered self-employed by the IRS. This means you are responsible for paying both income tax and self-employment tax on your net earnings.
What is Self-Employment Tax?
Self-employment tax is the Social Security and Medicare tax for individuals who work for themselves. It's analogous to the Social Security and Medicare taxes withheld from the pay of most wage earners. The self-employment tax rate is 15.3% on the first $168,600 (for 2024, $160,200 for 2023) of net earnings from self-employment, consisting of:
- 12.4% for Social Security
- 2.9% for Medicare
For earnings above the Social Security limit, only the 2.9% Medicare tax applies.
Calculating Net Earnings for Self-Employment Tax
You don't pay self-employment tax on your entire gross income. First, you subtract your deductible business expenses from your gross 1099 income. This yields your net earnings from self-employment. However, for tax purposes, you can deduct one-half of your self-employment tax liability. This means:
- Calculate gross income minus business expenses to get preliminary net earnings.
- Calculate the self-employment tax on 92.35% of these preliminary net earnings.
- Deduct one-half of the calculated self-employment tax from your taxable income.
The formula for the amount subject to self-employment tax is typically 0.9235 * (Gross Income - Business Expenses).
Calculating Income Tax
Your income tax is calculated based on your taxable income. Taxable income is your Adjusted Gross Income (AGI) minus your deductions (either the standard deduction or itemized deductions). For a self-employed individual, your AGI includes your net earnings from self-employment after the deduction for one-half of your self-employment tax. The actual income tax is then determined by applying the progressive tax brackets for your specific filing status and the tax year.
