Self-employment tax is the self-employed equivalent of FICA taxes—Social Security and Medicare—and it is one of the largest tax obligations for freelancers and sole proprietors. At 15.3% of net earnings, it can be a shock if you have not planned for it. This calculator breaks down the math clearly.
The good news is that you can deduct the employer-equivalent portion (7.65%) of SE tax as an above-the-line deduction on your income tax return. This template calculates that deduction for you, which reduces your adjusted gross income and, in turn, your income tax. Many self-employed individuals miss this deduction.
How to Use This Template
Enter Net Self-Employment Income
Input your total Schedule C net profit (or Schedule K-1 self-employment income). The template applies the 92.35% factor to determine your SE tax base.
Review the Tax Calculation
The template calculates Social Security tax (12.4% up to the wage cap) and Medicare tax (2.9% with no cap) separately so you can see each component.
Plan for Payments
Check the quarterly breakdown to see how much SE tax you owe each quarter. The template also shows your deductible employer-equivalent portion for income tax purposes.
Frequently Asked Questions
How is self-employment tax calculated?
Multiply your net self-employment income by 92.35%, then apply 15.3% (12.4% Social Security + 2.9% Medicare). Social Security tax caps at the annual wage base ($168,600 for 2024). Above $200,000, an additional 0.9% Medicare tax applies. This template handles all calculations.
Can I reduce my self-employment tax liability?
The best strategy is to maximize deductible business expenses to lower your net self-employment income. For higher earners, incorporating as an S-corp can reduce SE tax by paying yourself a reasonable salary. This template calculates your liability so you can evaluate whether an S-corp election makes sense.
