Self-Employment Tax Explained: How 1099 Taxes Work in 2026

Self-employment tax rate for 2026

You owe SE tax if your net earnings from self-employment are $400 or more. The calculation is done on Schedule SE.

How self-employment tax is calculated

Step 1: Find net profit (gross receipts minus business expenses) on Schedule C. Step 2: Multiply by 92.35% to get net earnings from self-employment. This mirrors the fact that employees do not pay FICA on the employer's half. Step 3: Multiply by 15.3% (or by 12.4% up to the Social Security wage base and 2.9% on the rest). Step 4: Deduct half of the SE tax as an adjustment to income on Schedule 1, which lowers income tax but not SE tax.

Example: $80,000 net profit. $80,000 x 0.9235 = $73,880 of net SE earnings. $73,880 x 15.3% = $11,303.64 of SE tax. Half of that, $5,651.82, is deductible.

Total 1099 taxes: a full 2026 example

Jordan is single, a full-time freelance designer with $80,000 of net profit in 2026, no other income.

• Self-employment tax: $11,304
• AGI: $80,000 - $5,652 (half of SE tax) = $74,348
• Taxable income before QBI: $74,348 - $16,100 standard deduction = $58,248
• Qualified business income deduction: 20% of the lesser of QBI ($74,348) or taxable income ($58,248) = $11,650
• Taxable income: $46,598, federal income tax about $5,344
• Total federal tax: about $16,647, or roughly 20.8% of profit, about $4,162 per quarter

High earners: the Social Security cap

The 12.4% Social Security portion stops at the wage base, $184,500 for 2026 (up from $176,100 in 2025). With $250,000 of net profit, net SE earnings are $230,875. Social Security tax is 12.4% of $184,500 = $22,878; Medicare is 2.9% of $230,875 = $6,695. The 0.9% Additional Medicare Tax applies to the $30,875 above $200,000 (single), adding about $278 on Form 8959. If you also have W-2 wages, those wages use up the Social Security cap first.

Quarterly estimated taxes

You generally must make estimated payments if you expect to owe at least $1,000 after withholding and credits. To avoid an underpayment penalty, pay the smaller of 90% of this year's tax or 100% of last year's tax (110% if last year's AGI was over $150,000, or $75,000 married filing separately), spread across the four due dates. Pay through IRS Direct Pay, your IRS Online Account or EFTPS.

Ways to lower self-employment tax legally

• Track every deductible business expense; each $1,000 of expenses saves about $141 of SE tax plus income tax.
• Use the home office deduction and actual or standard mileage for business driving.
• Retirement contributions (SEP-IRA, solo 401(k)) and self-employed health insurance cut income tax, though not SE tax.
• An S corporation election can reduce SE tax for profitable businesses that pay a reasonable salary, but it adds payroll and filing costs.

1099 forms: what you receive and what you report

Clients report payments to independent contractors on Form 1099-NEC, and payment apps and card processors use Form 1099-K. The One Big Beautiful Bill Act changed both thresholds. For payments made after 2025, the 1099-NEC and 1099-MISC reporting threshold rises from $600 to $2,000. The 1099-K threshold returns to more than $20,000 and more than 200 transactions.

These are only reporting thresholds for the payer. All self-employment income is taxable whether or not you receive a 1099, and the $400 self-employment tax threshold still applies. Keep your own income records, reconcile them with any forms you receive, and report gross receipts and expenses on Schedule C.

Side gig on top of a W-2 job: what the extra income costs

Most people who owe self-employment tax also have a regular job. Their W-2 wages already use up the low tax brackets, so side profit is taxed at their top bracket plus the full 15.3% SE tax.

Example: a single filer earns $60,000 in W-2 wages and makes $10,000 of net profit from weekend photography in 2026. SE tax is $1,413. After deducting half of it and taking the qualified business income deduction, the profit adds about $986 of federal income tax. Part of it is taxed at 12% and part at 22%, because it pushes taxable income over $50,400. The total extra federal tax is about $2,399, or 24% of the profit.

You do not have to send quarterly payments for this. You can ask your employer to withhold more by entering an extra amount in Step 4(c) of Form W-4. Federal withholding is treated as paid evenly through the year, no matter when it was taken out. That makes a late-year W-4 change a simple way to catch up and avoid an underpayment penalty.

Retirement plans that cut income tax for the self-employed

Self-employed people can shelter far more than a typical employee, which partly makes up for paying both halves of FICA. These plans lower income tax only, because SE tax is figured on net earnings before retirement contributions.

• In the full-time example above, a $10,000 solo 401(k) deferral would cut Jordan's federal income tax by about $960. That is a little under 12% because the contribution also trims the QBI deduction.
• A SEP-IRA can be set up and funded as late as your return due date, including extensions, so you can decide after the year ends. Solo 401(k) timing rules are stricter; check the IRS one-participant 401(k) page before relying on a late contribution.

Common 1099 tax mistakes

• Reporting only what appears on 1099 forms. Income below the new $2,000 1099-NEC threshold is still taxable.
• Treating the gross amount on a 1099-K as profit. Platform fees, refunds and personal transfers included in the gross amount must be backed out or deducted.
• Skipping the June estimated payment. It covers only April and May, so it falls due just two months after the April payment.
• Forgetting state estimated tax. Most income-tax states have their own quarterly payment rules.
• Mixing business and personal spending in one account, which makes deductions hard to prove in an audit.
