Mastering the Self-Employment Tax

Self-employment tax is a key aspect of taxation for U.S. freelancers, independent contractors, and small business owners. Unlike traditional employees, who have taxes withheld by employers, self-employed individuals must pay both the employee and employer portions of Social Security and Medicare taxes.

This guide will break down what self-employment tax is, how it's calculated, and strategies to manage it efficiently.

1. What is Self-Employment Tax?

Self-employment tax covers Social Security and Medicare taxes that self-employed individuals must pay on their net earnings. For employees, these taxes are split between the employer and employee. However, self-employed individuals are responsible for paying the full amount themselves.

• Social Security Tax Rate: 12.4%
• Medicare Tax Rate: 2.9%

Together, these taxes total 15.3% of net earnings. This combined amount is referred to as the self-employment tax.

Who Pays Self-Employment Tax?

• Freelancers
• Independent Contractors
• Sole Proprietors
• Partners in Partnerships
• Members of LLCs taxed as partnerships

If your net earnings from self-employment exceed $400 in a year, you must file Schedule SE and pay self-employment tax.

2. How is Self-Employment Tax Calculated?

Follow these basic steps to determine your self-employment tax:

Step 1: Calculate Net Earnings

Net earnings are calculated by subtracting business expenses from your gross income. Use Schedule C to list income and deductible business expenses.

Step 2: Apply the Self-Employment Tax Rate

You pay self-employment tax on 92.35% of your net earnings, as the IRS allows a small deduction to account for paying both the employee and employer portions.

Step 3: Self-Employment Tax Formula

Self-Employment Tax = (Net Earnings × 92.35%) × 15.3%

For example, if your net earnings are $50,000:

Self-Employment Tax = (50,000 × 92.35%) × 15.3% = 46,175 × 15.3% = $7,062.78

Step 4: Additional Medicare Tax

If your net earnings exceed $200,000 (or $250,000 for married couples filing jointly), you may be subject to an additional 0.9% Medicare tax on the excess.

3. Deducting Half of the Self-Employment Tax

One benefit for self-employed individuals is that the IRS allows a deduction for 50% of the self-employment tax when calculating Adjusted Gross Income (AGI). This deduction helps reduce your taxable income.

For example, if your self-employment tax is $7,062.78, you can deduct $3,531.39 on your 1040 tax form as an adjustment to income.

4. Estimated Tax Payments

Self-employed individuals don’t have taxes withheld from their earnings, so they must make quarterly estimated tax payments to cover income and self-employment taxes.

• Payments are due on April 15, June 15, September 15, and January 15.
• If you expect to owe $1,000 or more in taxes, you must pay estimated taxes.

How to Calculate Estimated Tax Payments:

1. Estimate your total annual income.
2. Subtract business expenses to find your net income.
3. Multiply your net income by 92.35% to get the amount subject to self-employment tax.
4. Apply the 15.3% self-employment tax rate.
5. Add any federal income tax you expect to owe.
6. Divide the total by four for your quarterly payments.

5. How to Reduce Your Self-Employment Tax Liability

There are several strategies to reduce the self-employment tax burden.

A. Maximize Business Deductions

Deducting business expenses lowers your net earnings, which reduces your self-employment tax. Common deductions include:

• Home office expenses
• Internet and phone bills
• Business supplies
• Travel and meal expenses
• Vehicle mileage

B. Contribute to a Retirement Plan

Contributing to a Solo 401(k) or SEP-IRA can lower your taxable income, as these contributions are tax-deductible.

• SEP-IRA: Contribute up to 25% of net earnings or $66,000 (for 2023), whichever is lower.
• Solo 401(k): Contribute up to $22,500 (or $30,000 if age 50+) as an employee, plus an additional 25% of net earnings as the employer, for a total of $66,000.

C. Form an S-Corporation

If your earnings reach a certain level, forming an S-corporation may reduce self-employment taxes. You can pay yourself a salary (subject to self-employment tax) and take the remaining profits as distributions, which are not subject to self-employment tax.

D. Health Insurance Deduction

If you pay for your own health insurance, you can deduct premiums for yourself, your spouse, and dependents, which helps reduce taxable income.

6. Self-Employment Tax for Different Business Structures

Different business structures affect how self-employment tax is calculated:

• Sole Proprietorships and Single-Member LLCs: Income is reported on Schedule C and subject to self-employment tax.
• Partnerships and Multi-Member LLCs: Partners are subject to self-employment tax on their share of income.
• S-Corporations: Shareholders pay self-employment tax only on wages, not distributions.

7. Self-Employment Tax vs. Income Tax

It’s important to differentiate between self-employment tax and income tax. Self-employment tax covers Social Security and Medicare, while income tax applies to all your income, including wages, interest, and dividends.

You must pay both self-employment tax and income tax, but you can deduct half of the self-employment tax from your taxable income.

Conclusion

Understanding self-employment tax is essential for freelancers, contractors, and small business owners to avoid surprises. Knowing how it’s calculated, taking advantage of deductions, and planning for estimated payments can help minimize your tax burden.

• Self-employment tax covers both Social Security and Medicare for the self-employed.
• The tax rate is 15.3% on 92.35% of net earnings.
