One of the most common surprises for newly self-employed beauty professionals is the self-employment (SE) tax. When you were an employee at a salon, you paid 7.65% in FICA taxes (Social Security + Medicare) and your employer paid another 7.65% on your behalf.
When you work for yourself, you pay both sides. That's 15.3% on top of your regular income tax.
What Is Self-Employment Tax?
Self-employment tax is the IRS's way of collecting Social Security and Medicare contributions from people who don't have an employer doing it for them. It consists of:
- Social Security: 12.4% on net self-employment income up to $168,600 (2026 limit)
- Medicare: 2.9% on all net self-employment income (no cap)
- Additional Medicare: 0.9% if your income exceeds $200,000 (single) or $250,000 (married)
For most beauty professionals earning under $168,600/year, the effective SE tax rate is 15.3%.
What Is SE Tax Calculated On?
SE tax is calculated on your net self-employment income — that's your gross income minus your deductible business expenses. This is why tracking and claiming all your deductions is so important: every deductible dollar reduces not just your income tax, but also your SE tax.
Example: You earn $60,000 in gross income and have $15,000 in deductible expenses (booth rent, supplies, mileage, education). Your net SE income is $45,000. Your SE tax would be approximately $6,358.
How SE Tax Stacks With Income Tax
Here's where beauty professionals often get caught off guard. Your total federal tax bill includes both SE tax AND income tax on the same income. Let's look at a real example:
| Item | Amount |
|---|---|
| Gross income | $55,000 |
| Business expenses (deductions) | – $12,000 |
| Net self-employment income | $43,000 |
| SE tax (15.3%) | – $6,579 |
| SE tax deduction (half of above) | – $3,290 |
| Adjusted gross income | $39,710 |
| Standard deduction (single, 2026) | – $15,000 |
| Taxable income | $24,710 |
| Federal income tax (12% bracket) | ≈ $2,820 |
| Total federal tax owed | ≈ $9,399 |
On $55,000 of gross income, this beauty professional owes roughly $9,400 in federal taxes — about 17% of gross income. State taxes are on top of this.
How to Set Aside the Right Amount
Given SE tax plus income tax, the general rule is to set aside 25–30% of your net income for taxes. If you're in a higher income bracket or live in a high-tax state like California or New York, lean toward 30–35%.
- Set aside money after every client payment, not at the end of the month
- Keep it in a separate savings account — make it hard to touch
- Pay quarterly to avoid underpayment penalties
- Track every deductible expense to reduce your net income
The Role of Deductions
Every dollar you can legitimately deduct reduces your net SE income — which reduces both your SE tax and your income tax. A $1,000 deduction might save you $150 in SE tax plus $120 in income tax, for a total saving of $270. This is why detailed expense tracking is worth every minute.
SuitesBooks tracks your income and expenses in real time and shows you your current estimated SE tax on your dashboard — so there are never any surprises.
When to Talk to a Tax Professional
While SuitesBooks helps you track everything and estimates your quarterly payments, a licensed CPA or enrolled agent who works with self-employed clients can help you structure your business, maximize deductions, and potentially save thousands. Consider booking a session with a tax pro at least once — especially in your first year of self-employment.
