How to Pay Self-Employment Tax in 2026 — Step-by-Step Guide

Self-employment tax is the #1 surprise for new freelancers. When you leave a W-2 job, your employer was secretly paying half your Social Security and Medicare taxes. Now you pay both halves — 15.3% on top of regular income tax. Here's exactly how to handle it.

What Is Self-Employment Tax?

Self-employment (SE) tax = Social Security (12.4%) + Medicare (2.9%) = 15.3%

It applies to net self-employment income — that's your gross freelance income minus business expenses.

Important: SE tax is separate from federal income tax. You pay both. This is why freelancers often need to save 25–35% of every payment they receive.

SE Tax Rate Breakdown

The 92.35% rule: SE tax doesn't apply to 100% of your net income — it applies to 92.35% (because employees don't pay SE tax on the employer's share). So multiply your net income by 0.9235 first, then by 15.3%.

The example below is a single filer with no other income.

Step 1: Calculate Your Net Self-Employment Income

Gross freelance income:          $75,000
Minus business deductions:      -$12,000
= Net self-employment income:    $63,000

Common deductions: home office, mileage (72.5¢ a mile for January to June 2026, 76¢ from July), software subscriptions, professional development, equipment. Self-employed health insurance is not one of them: it is an adjustment on Schedule 1 that lowers income tax only, not SE tax.

Step 2: Calculate Your SE Tax

Net SE income:              $63,000
× 92.35%:                   $58,181
× 15.3%:                    $8,902 SE tax owed

You can deduct half of your SE tax ($4,451) from your net profit when calculating federal income tax. Schedule SE works it out, and it goes on Schedule 1.

Step 3: Calculate Federal Income Tax

Income tax starts from net profit, not from what you invoiced.

Net profit:                 $63,000
Minus half of SE tax:       -$4,451
Minus standard deduction:   -$16,100
Minus QBI deduction:        -$8,490
= Taxable income:            $33,959

Federal income tax (2026 brackets):
  10% on $12,400:           $1,240
  12% on $21,559:           $2,587
= Federal income tax:        $3,827

The QBI deduction is 20% of net profit minus half of SE tax, capped at 20% of taxable income before it ($42,449 here): the lesser of $11,710 and $8,490.

Step 4: Determine Your Total Tax Bill

SE tax:                     $8,902
Federal income tax:         $3,827
= Total federal:            $12,729 (20.2% of net profit)

State income tax comes on top, worked out on the state's own brackets: none in Texas, $1,552 in California on the same income.

Step 5: Pay Through Estimated Quarterly Taxes

The IRS doesn't wait until April — they want taxes paid as you earn. Make four quarterly payments:

How much to pay each quarter: Total tax estimate ÷ 4. Or use last year's total tax as your baseline (the "safe harbor" method).

How to Actually Make the Payment

Option 1: IRS Direct Pay (Recommended — Free)

1. Go to irs.gov/payments
2. Click "Make a Payment"
3. Select "Estimated Tax" as the reason
4. Enter your bank account info
5. Confirm and save your confirmation number

Option 2: EFTPS (Electronic Federal Tax Payment System)

Best for recurring quarterly payments. Sign up at eftps.gov — schedule all four payments at once.

Option 3: Mail a Check

Make check payable to "United States Treasury." Include your SSN and "2026 Form 1040-ES" in the memo. Mail with the 1040-ES voucher to the IRS address for your state.

Option 4: IRS2Go App

Mobile payments for Direct Pay — same as Option 1, just on your phone.

How to File SE Tax at Year-End

SE tax is reported on Schedule SE (Form 1040). You'll also need:

• Schedule C — profit or loss from your business
• Form 1040 — your main tax return

If you used software (TurboTax, TaxAct, etc.) or a CPA, they handle Schedule SE automatically once you enter your freelance income and expenses.

4 Legal Ways to Reduce Your SE Tax

1. Maximize Business Deductions

Every dollar of legitimate business expense reduces your net SE income — and therefore your SE tax. Track everything: home office, software, mileage, phone. (Health insurance premiums do not count here: they reduce income tax only.)

2. Contribute to a Retirement Account

Solo 401(k) and SEP-IRA contributions for yourself reduce your taxable income but not your SE tax: a sole proprietor deducts them on Schedule 1, after SE tax is figured on the Schedule C profit.

3. Elect S-Corporation Status

Once you earn $50,000+ consistently, an S-Corp can save thousands. You pay yourself a "reasonable salary" (which has SE tax) and take the rest as distributions (no SE tax). Use our S-Corp Tax Savings Calculator to see if it makes sense.

4. Hire a Spouse or Family Member

Paying legitimate wages to a spouse or child shifts income and may reduce SE tax liability. Requires actual work performed and fair-market wages.

Frequently Asked Questions

Q: Do I owe SE tax if I only made $500 freelancing? A: SE tax applies if your net self-employment income is $400 or more. Below that threshold, you don't file Schedule SE.

Q: What if I have both a W-2 job and freelance income? A: You only pay SE tax on your freelance income. For Social Security, the W-2 withholding counts toward the $184,500 cap — so if you're close to the cap at your day job, your SE tax may be lower.

Q: Can I deduct SE tax from my taxes? A: Yes — you can deduct 50% of SE tax from your adjusted gross income on Form 1040. This is an "above-the-line" deduction and happens automatically on your return.

Q: What if I can't pay? A: File your return on time even if you can't pay. Then set up an IRS installment agreement at irs.gov/payments. Interest and late-payment penalties are smaller than failure-to-file penalties.
