These are the questions we hear most from 1099 contractors, freelancers, and gig workers. Every answer reflects IRS rules for the 2026 tax year and links to the calculator or source behind it. When a topic is fact-specific — multi-state income, an entity election, or a large income swing — the right move is still to confirm with a licensed CPA or enrolled agent.

SE tax is 15.3% (12.4% Social Security + 2.9% Medicare) on your net self-employment earnings. Unlike W-2 employees, whose employers pay half of these taxes, self-employed individuals must pay both the employer and employee portions. However, you can deduct 50% of your SE tax on your federal return as an above-the-line deduction. If your net earnings are under $400, you generally do not owe SE tax.
Yes, if you expect to owe $1,000 or more in federal income tax after subtracting withholding and credits. The IRS requires quarterly estimated tax payments to avoid underpayment penalties. The 2026 due dates are: April 15, June 15, September 15 (2026), and January 15 (2027). If a due date falls on a weekend or holiday, the deadline moves to the next business day. Use our Quarterly Estimate Calculator to calculate your payment amounts.

See our Privacy Policy for full details.The Qualified Business Income (QBI) deduction allows eligible self-employed individuals to deduct up to 20% of their qualified business income from their taxable income. This deduction was made permanent by recent tax law extensions. However, eligibility depends on your total taxable income, business type, and whether you are in a "specified service trade or business" (SSTB). High earners (above $191,950 single / $383,900 joint in 2026) face phase-out restrictions. Use our Base SE Tax Calculator to estimate your QBI deduction.
S-Corp election typically saves on SE tax when net profit exceeds $60,000-$80,000. You pay yourself a "reasonable salary" (subject to payroll tax) and take the remaining profit as distributions (not subject to SE tax). However, S-Corp status adds $1,000-$3,000 per year in administrative costs (payroll, tax filings, state fees). Use our S-Corp vs Sole Prop Calculator to find your break-even point. The salary must be "reasonable" — typically 50%-70% of net profit for most freelancers.
Nine states have no state income tax: Texas, Florida, Washington, Tennessee, Wyoming, South Dakota, Nevada, Alaska, and New Hampshire (NH only taxes interest and dividends, not earned income). If you live in one of these states, you only owe federal SE tax — a significant savings. Use our State SE Tax Calculator to compare your tax burden across states.
Common deductible expenses include: home office (simplified: $5/sq ft, max 300 sq ft); business mileage (70¢/mile in 2026); equipment and software (computers, furniture, tools); professional services (CPA, legal, bookkeeping); marketing and advertising; business insurance premiums; and continuing education and certifications. Keep receipts for all expenses — the IRS may require proof if you are audited. Use our Business Write-Off Builder to track all your expenses.
Use IRS Form 1040-ES to calculate and pay quarterly estimated taxes. You can pay: (1) Online via IRS Direct Pay; (2) By phone via the IRS2Go app; (3) By mail with a check and payment voucher. The IRS recommends paying at least 90% of your current year's tax or 100% of last year's tax (110% if AGI > $150,000) to avoid underpayment penalties. Use our Quarterly Estimate Calculator to determine your payment amounts.
The IRS requires you to file Schedule SE and pay self-employment tax if your net self-employment earnings (gross 1099 income minus business expenses) are $400 or more. If your net earnings are below $400, you generally do not owe SE tax — though you may still need to file a federal income tax return if your total income exceeds the standard deduction ($16,100 for single filers in 2026). Note: some states have different thresholds for state income tax filing.
Yes, if you are self-employed and not eligible for an employer-subsidized health plan (including through your spouse's employer), you can deduct 100% of your health insurance premiums for yourself, your spouse, and your dependents. This is an above-the-line deduction, meaning it reduces your AGI directly. The deduction is reported on Schedule 1 (Form 1040) and is subject to net profit limitations. Use our Full Freelance Tax Calculator to estimate your tax savings from health insurance deductions.
High-earning self-employed individuals may be subject to an Additional Medicare Tax of 0.9% on earned income above $200,000 for single filers (or $250,000 for married filing jointly). This brings the total Medicare tax rate to 3.8% for high earners. Unlike the regular Medicare tax, there is no employer portion for the Additional Medicare Tax — you pay the full 0.9% via Form 8959. Use our Medicare Surtax Calculator to check if this applies to you.
Report 1099-NEC and 1099-MISC income on Schedule C (Form 1040) as "Gross receipts or sales". You can deduct business expenses on Schedule C, then transfer the net profit to Schedule SE to calculate your SE tax. If you have expenses of $5,000 or less, you may be able to file Schedule C-EZ (though this form was discontinued after 2025; use Schedule C for 2026). Keep all receipts and records to substantiate your expense deductions in case of an IRS audit.
