Frequently Asked Questions
Q
What is self-employment tax?
Self-employment tax is 15.3% (12.4% Social Security + 2.9% Medicare) on net self-employment income. This is both the employer and employee portions of FICA that W-2 employees split with their employer.
Social Security portion (12.4%) applies only up to the $184,500 wage base cap for 2026
Medicare portion (2.9%) has no income cap and applies to all net earnings
Additional 0.9% Medicare surtax kicks in above $200,000 (single) or $250,000 (married filing jointly)
You can deduct half of your SE tax from gross income, saving roughly $1,000 per $13,000 of SE tax paid
Q
How do I pay 1099 taxes?
Make quarterly estimated tax payments by April 15, June 15, September 15, and January 15. Use IRS Form 1040-ES. Underpaying may result in penalties.
Pay at least 90% of current-year tax or 100% of prior-year tax (110% if AGI exceeds $150,000) to avoid penalties
Use IRS Direct Pay or EFTPS for free electronic quarterly payments
Underpayment penalty rate is the federal short-term rate plus 3 percentage points (7% for the quarters beginning July 1 and October 1, 2026)
Set aside 25–30% of every payment you receive into a separate savings account for taxes
Q
What expenses can I deduct?
Common deductions: home office, equipment, software, internet, phone, travel, health insurance, retirement contributions, professional services, and supplies. Keep receipts for all business expenses.
Home office simplified deduction: $5 per sq ft up to 300 sq ft ($1,500 max)
Vehicle mileage: 72.5 cents per mile through June 30, 2026, then 76 cents from July 1
SEP-IRA contributions: up to 25% of net SE income, maxing at $72,000 for 2026
Self-employed health insurance premiums are 100% deductible above the line
Equipment under $2,500 per item can be expensed immediately under the de minimis safe harbor
Q
What is the QBI deduction?
The Qualified Business Income deduction allows eligible self-employed individuals to deduct up to 20% of net business income from taxable income. Income limits and business type affect eligibility.
Saves up to $1 in taxes for every $5 of qualified business income
Phase-out begins at $201,750 (single) or $403,500 (married filing jointly) for 2026
Specified service trades (law, medicine, consulting) lose the deduction above phase-out thresholds
On $85,000 net income, the QBI deduction is $17,000, reducing your federal tax by roughly $2,000–$4,000
Q
Do I need to file if I made under $400?
If net self-employment income is $400 or more, you must file a tax return and pay self-employment tax. Below $400, you may not need to file unless you have other income.
The $400 threshold applies to net income (gross minus expenses), not gross receipts
Even at $400 net, your SE tax is about $57 (15.3% × $400 × 0.9235)
You may still owe income tax if your total income from all sources exceeds the standard deduction ($16,100 single)
Platforms like Venmo and PayPal report payments over $600 via 1099-K, but filing is based on net income
Q
1099 vs W-2: which pays more taxes?
1099 contractors typically pay more in total FICA taxes (15.3% vs 7.65% for W-2). However, 1099s can deduct business expenses and half of SE tax, which may offset some of the difference.
A W-2 employee earning $100,000 pays $7,650 in FICA; a 1099 contractor pays $14,130 in SE tax on the same gross
The SE tax deduction (half of $14,130 = $7,065) and QBI deduction ($20,000) reduce the gap significantly
Business expense deductions (home office, equipment, mileage) can save $3,000–$10,000+ annually
1099 contractors should charge 15–25% more than comparable W-2 rates to cover SE tax and benefits
Net income = $100,000 - $15,000 = $85,000. SE taxable = $85,000 x 0.9235 = $78,498. SS tax = $78,498 x 12.4% = $9,734. Medicare = $78,498 x 2.9% = $2,276. SE tax = $12,010. SE deduction = $6,005. QBI deduction = $85,000 x 20% = $17,000. Taxable income = $85,000 - $6,005 - $16,100 - $17,000 = $45,895. Federal tax on $45,895 through the 2026 brackets = $1,240 + $4,019 = $5,259. State = $85,000 x 5% = $4,250. Total = $21,520. Quarterly = $5,380.
Net income = $60,000 - $5,000 = $55,000. SE taxable = $55,000 x 0.9235 = $50,793. SS tax = $50,793 x 12.4% = $6,298. Medicare = $50,793 x 2.9% = $1,473. SE tax = $7,771. SE deduction = $3,886. QBI deduction = $55,000 x 20% = $11,000. Taxable income = $55,000 - $3,886 - $16,100 - $11,000 = $24,014. Federal tax on $24,014 = $12,400 x 10% + $11,614 x 12% = $1,240 + $1,394 = $2,634. Total = $10,405.
Formulas Used
Net Self-Employment Income
Net Income = Gross 1099 Income - Business Expenses
Deductible business expenses reduce your taxable self-employment income.
Where:
Gross 1099 Income= Total income received on 1099 forms
Business Expenses= Deductible expenses like home office, equipment, software, travel
Self-Employment Tax
SE Tax = (Min(Net Income x 92.35%, $184,500) x 12.4%) + (Net Income x 92.35% x 2.9%)
Self-employment tax covers both employer and employee portions of Social Security (12.4%) and Medicare (2.9%).
Where:
92.35%= Adjustment factor (100% - half of 15.3% SE tax rate)
$184,500= 2026 Social Security wage base cap
Federal Income Tax (for 1099)
Taxable Income = Net Income - (SE Tax / 2) - Standard Deduction - QBI Deduction
Federal tax is calculated on income after deducting half of SE tax, the standard deduction, and the QBI deduction (20% of net income).
Where:
SE Tax / 2= Deductible half of self-employment tax
Standard Deduction= $16,100 (single) or $32,200 (married) for 2026
QBI Deduction= Qualified Business Income deduction: 20% of net self-employment income
Total Tax & Quarterly Payment
Total Tax = SE Tax + Federal Income Tax + State Tax; Quarterly = Total Tax / 4
Total annual tax obligation divided into 4 quarterly estimated payments.
Where:
State Tax= Net income x state tax rate
Quarterly Payment= Due April 15, June 15, September 15, January 15

The 15.3% Self-Employment Tax Explained
15.3% of net self-employment income goes to self-employment (SE) tax — 12.4% for Social Security and 2.9% for Medicare. On $85,000 net income, that’s $12,010 in SE tax alone, before any federal or state income tax. W-2 employees split this cost with their employer (each paying 7.65%), but 1099 contractors bear both halves.
The calculation applies to 92.35% of net income, not the full amount. This adjustment (100% minus half of 15.3%) exists because W-2 employers don’t pay FICA on the employer’s portion. For $85,000 net: $85,000 × 0.9235 = $78,498 is the SE tax base. Social Security tax: $78,498 × 12.4% = $9,734. Medicare tax: $78,498 × 2.9% = $2,276. Total SE tax: $12,010.
Social Security tax applies only up to the $184,500 wage base cap (2026). Once your SE-taxable income exceeds this threshold, only the 2.9% Medicare portion continues. An additional 0.9% Medicare surtax kicks in above $200,000 (single) or $250,000 (married filing jointly), bringing the effective Medicare rate to 3.8%.

Quarterly Estimated Tax Payments
Quarterly payments are due April 15, June 15, September 15, and January 15, and must total at least 90% of your current-year tax or 100% of your prior-year tax (110% if AGI exceeds $150,000) to avoid underpayment penalties. On $85,000 net income with $21,520 total tax, each quarterly payment is $5,380.
The IRS underpayment penalty rate is the federal short-term rate plus 3 percentage points — 7% for the quarters beginning July 1 and October 1, 2026. Missing a single quarterly payment of $5,380 by 6 months would cost roughly $188 in penalties. Use IRS Direct Pay or EFTPS (Electronic Federal Tax Payment System) for free electronic submissions.
The safest approach: set aside 25–30% of every payment you receive into a separate savings account. For a freelancer earning $8,333/month ($100,000/year gross), that means automatically transferring $2,083–$2,500/month to a tax savings account. This covers SE tax, federal income tax, and state tax with a small buffer.
Set aside 25–30% of every client payment into a dedicated tax savings account immediately. Quarterly payment deadlines are April 15, June 15, September 15, and January 15.

Key Deductions That Reduce Your 1099 Tax Bill
The SE tax deduction alone saves $6,005 on $85,000 net income — you deduct half of your $12,010 SE tax directly from gross income, reducing your federal taxable base before bracket calculations. This is an above-the-line deduction that requires no itemizing.
The Qualified Business Income (QBI) deduction allows eligible self-employed individuals to subtract 20% of net business income from their taxable income. On $85,000 net, that’s a $17,000 QBI deduction, saving approximately $2,000–$4,000 in federal tax depending on your bracket. Phase-out begins at $201,750 (single) for specified service trades like law, medicine, and consulting.
Common business expense deductions can reduce net income by $10,000–$25,000 annually: home office ($5/ft² up to 300 ft² = $1,500 max simplified), vehicle mileage (72.5 cents/mile through June 2026, 76 cents after), SEP-IRA contributions (up to 25% of net SE income, max $72,000), and self-employed health insurance premiums (100% deductible above the line).
Half of SE tax — $6,005 deduction on $85,000 net income (above-the-line, no itemizing needed)
QBI deduction (20%) — $17,000 on $85,000 net, saving $2,000–$4,000 in federal tax
Home office simplified — $5/ft² × up to 300 ft² = $1,500 max deduction
Vehicle mileage — 72.5 cents/mile through June 30, 2026 and 76 cents after, e.g., 10,000 business miles in the second half = $7,600 deduction
SEP-IRA — up to 25% of net SE income ($21,250 on $85,000), reduces taxable income dollar-for-dollar
Health insurance — self-employed premiums are 100% deductible above the line

Using the 1099 Tax Calculator Step by Step
Enter your gross 1099 income and total business expenses. The calculator computes net income, then applies the 92.35% adjustment, Social Security tax (capped at $184,500), Medicare tax (uncapped), and the half-SE deduction automatically. Federal income tax runs through the 2026 bracket schedule after subtracting the standard deduction ($16,100 single / $32,200 married) and QBI deduction.
State tax is simplified as a flat percentage of net income. Enter your state’s approximate rate (0% for Texas, Florida, Wyoming; 5% for many states; 9–13% for California, New York). The calculator shows total annual tax, quarterly payment amount, effective tax rate, marginal rate, and take-home pay.

1099 vs. W-2: The Real Tax Difference
A W-2 employee earning $100,000 pays $7,650 in FICA taxes (7.65%), while a 1099 contractor with the same gross pays approximately $14,130 in SE tax (15.3% of 92.35%) — an $6,480 annual difference that is the single biggest tax disadvantage of independent contracting.
However, the gap narrows significantly after deductions. The SE tax deduction ($7,065), QBI deduction ($20,000 on $100,000 net), and business expense deductions ($10,000–$25,000) can save $8,000–$15,000 in taxes that W-2 employees cannot claim. A 1099 contractor also has access to SEP-IRA limits of $72,000 versus $24,500 for a W-2 employee’s 401(k).
The rule of thumb: 1099 contractors should charge 15–25% more than comparable W-2 rates to cover the SE tax difference, lack of employer-provided benefits (health insurance, retirement match, paid time off), and the administrative cost of self-employment. The freelance rate calculator and self-employment tax calculator provide more detailed rate comparisons.
