If you're an independent contractor, freelancer, or self-employed individual, you likely receive income reported on Form 1099-NEC (Nonemployee Compensation) or other 1099 forms. Unlike traditional employees, no taxes are withheld from your 1099 income, meaning you're responsible for calculating and paying your own taxes, often through estimated quarterly payments.
What is Self-Employment Tax?
Self-employment tax is a combination of Social Security and Medicare taxes for self-employed individuals. For 2023, the self-employment tax rate is 15.3% on your net earnings from self-employment. This rate consists of 12.4% for Social Security (up to an annual earnings limit) and 2.9% for Medicare (no earnings limit). You pay self-employment tax on 92.35% of your net earnings from self-employment.
Business Expenses and Deductions
A significant advantage of being self-employed is the ability to deduct ordinary and necessary business expenses. These expenses reduce your net earnings, which in turn lowers both your self-employment tax and your income tax liability. Common deductible expenses include home office deductions, business supplies, professional development, health insurance premiums (under certain conditions), and more.
The Half Self-Employment Tax Deduction
The IRS allows you to deduct one-half of your self-employment tax from your gross income when calculating your Adjusted Gross Income (AGI). This deduction helps reduce your overall income tax burden.
Estimated Income Tax
In addition to self-employment tax, your 1099 income is also subject to federal income tax (and state income tax, if applicable). The amount of income tax you owe depends on your total income, filing status, deductions, and credits. This calculator provides an estimate based on a marginal tax rate you provide, but for precise income tax calculations, consulting a tax professional or using tax software is recommended.
