Estimate your 2024 Social Security and Medicare taxes with confidence.
If you work for yourself, you're considered both an employee and an employer. This means you are responsible for paying the full Social Security and Medicare taxes that are typically split between an employee and their employer. This is known as the self-employment (SE) tax. Calculating this tax can be confusing, but our Self-Employment Tax Calculator is designed to simplify the process.
This guide will explain how to use our calculator, break down the components of the SE tax, and help you understand your tax obligations as a self-employed individual in the USA.
How to Use the Self-Employment Tax Calculator
Our calculator provides a quick and accurate estimate of your SE tax liability based on the 2024 IRS rules. Follow these simple steps:
- Enter Your Net Earnings from Self-Employment: This is the most important field. Enter your total business income minus your ordinary and necessary business expenses. This is the profit you made from your business.
- Enter W-2 Wages (Optional but Recommended): If you also have a traditional job where you receive a W-2 form, enter your total wages from that job here. This is crucial for accurately calculating the Social Security portion of your tax, as there is an annual income limit for Social Security contributions.
- Click "Calculate Tax": Once your information is entered, click the button to see your estimated tax breakdown.
- Review Your Results: The calculator will provide a detailed summary, including your taxable earnings, the amount of Social Security and Medicare tax you owe, the total SE tax, and the portion of that tax you can deduct from your income tax.
Breaking Down the Self-Employment Tax
The self-employment tax is not an additional income tax; it is the Social Security and Medicare tax for individuals who work for themselves. Let's break down how it's calculated.
Step 1: Determine Your Taxable Earnings
Not all of your net earnings are subject to SE tax. You can only be taxed on 92.35% of your net earnings from self-employment.
Formula:
Taxable Earnings = Net Earnings × 0.9235
Step 2: Calculate Social Security and Medicare Taxes
The SE tax is composed of two parts:
- Social Security Tax: The rate is 12.4%. For 2024, this tax only applies to the first $168,600 of your combined earnings (from both self-employment and any W-2 jobs). Our calculator automatically accounts for this limit.
- Medicare Tax: The rate is 2.9%. Unlike Social Security, there is no wage base limit for Medicare tax; it applies to all of your taxable earnings.
Formulas:
Social Security Tax = Taxable Earnings (up to limit) × 0.124
Medicare Tax = Taxable Earnings × 0.029
Step 3: Calculate the Total SE Tax and Deduction
The total SE tax is simply the sum of the Social Security and Medicare taxes. The good news is that you can deduct half of your total SE tax when calculating your adjusted gross income (AGI) for income tax purposes.
Formulas:
Total SE Tax = Social Security Tax + Medicare Tax
Deductible Portion = Total SE Tax / 2
This deduction is an "above-the-line" deduction, meaning you can take it even if you don't itemize deductions on your tax return. Keywords: self employment tax rate 2024, calculate FICA tax, 1099 tax calculator.
Who Needs to Pay Self-Employment Tax?
According to the IRS, you generally must pay SE tax if you had net earnings of $400 or more from self-employment. This applies to you if you are a:
- Freelancer or Independent Contractor: Such as writers, designers, consultants, and developers who receive 1099-NEC forms.
- Small Business Owner: Including sole proprietors and partners in a partnership.
- Gig Economy Worker: Such as drivers for ride-sharing services or delivery drivers.
