Why 1099 pay-stub math is different from W-2
W-2 employees split FICA 50/50 with their employer (7.65% each). 1099 contractors pay both halves — 15.3% on the first ~$168k of net self-employment earnings, then 2.9% Medicare on every additional dollar. That's why a freelancer earning $100k gross typically nets less than a W-2 employee earning $85k. The fix isn't to charge less — it's to set up retirement vehicles and entity structures W-2 employees can't touch.
- • Half the SE tax is deductible — most calculators get this wrong.
- • QBI (Section 199A) can knock 20% off taxable business income for many freelancers under the phase-out thresholds.
- • Quarterly estimated taxes are due April 15, June 15, Sept 15, Jan 15 — see our quarterly tax tool below.
The S-corp election crossover
Once net business income clears roughly $80–$100k, electing S-corp taxation (Form 2553) usually saves 5–15% of take-home by letting you pay yourself a 'reasonable salary' (subject to FICA) and take the rest as distributions (not subject to SE tax). Below ~$60k net, the payroll/accounting overhead usually outweighs the savings.
Freelancer take-home is brutal math: you pay both halves of FICA, your own income tax, your own state tax, quarterly estimated payments, and you fund your own retirement and health insurance. This calculator runs the full stack from gross 1099 income down to the dollars actually hitting your checking account — so you stop being surprised in April.
What each input means
Get these inputs right and the output is reliable. Get them wrong and the calculator just multiplies bad assumptions.
Gross 1099 income
Total invoiced revenue for the year, before any deductions.
Typical range: $60k–$200k for solo freelancers; $200k+ once you specialize or staff up.
Business deductions
Legitimate Schedule C expenses: software, equipment, home office, mileage, contractors.
Typical range: $3k–$15k for solos; $25k+ once you have ad spend, contractors, or co-working.
Federal effective tax rate
Blended federal income tax rate after standard deduction and bracket math. NOT your top bracket.
Typical range: 10–14% on $50–80k taxable; 15–20% on $80–150k; 22–28% above.
State tax rate
Effective state income tax. Use 0 if you're in TX/FL/WA/NV/TN/SD/AK/WY/NH.
Typical range: 0–13% depending on state. CA top blended ~10%, NY ~8%, IL ~5%.
Retirement contribution
Solo 401k or SEP-IRA deduction. Reduces taxable income dollar-for-dollar.
Typical range: $5k–$30k for most solos; up to $69k via Solo 401k for high earners.
Worked examples
Real scenarios with the math walked through line by line.
Solo designer, $120k gross in California
Scenario: $120k revenue, $8k expenses, ~16% federal effective, 8% CA effective, $12k SEP-IRA.
Math: Net SE income = $112k. SE tax = $112k × 0.9235 × 0.153 = $15,827. SE tax deduction = $7,914. Taxable income = $112k − $7,914 − $12k = $92,086. Federal = $14,734. State = $8,800. Total tax = $39,361. Take-home = $120k − $8k − $39,361 = $72,639. Effective take-home rate = 60.5%.
Outcome: Roughly 40% of gross goes to taxes + expenses. Plan for it monthly, not annually.
Senior dev consultant, $250k in Texas
Scenario: $250k revenue, $15k expenses, 24% federal effective, 0% state, $40k Solo 401k.
Math: Net SE = $235k. SE tax = $235k × 0.9235 × 0.153 ≈ $33,212 (but capped on SS portion above $168.6k base in 2026). Use ~$22k as cleaner estimate. Half deductible = $11k. Taxable = $235k − $11k − $40k = $184k. Federal = $44,160. Total tax ≈ $66k. Take-home ≈ $169k.
Outcome: TX residency + Solo 401k saves ~$25k/yr vs CA. Worth modeling explicitly before relocating.
Common mistakes
Where this calculation usually goes wrong in the real world.
- Forgetting self-employment tax. 15.3% on top of income tax is the #1 surprise for new freelancers.
- Not deducting half of SE tax above the line. That's a real deduction the IRS gives you — take it.
- Treating gross 1099 income like a W-2 salary. A $100k 1099 ≠ $100k W-2; it's roughly equivalent to a $70–80k W-2 with benefits.
- Skipping retirement contributions because cashflow is tight. Solo 401k contributions are the single biggest legal tax shelter for freelancers.
- Missing the QBI 20% deduction. Most service freelancers under the income threshold get a 20% pass-through deduction on net business income.
When to use this calculator
- Setting freelance rates so your take-home actually matches your salary target.
- Deciding whether to relocate to a no-income-tax state.
- Planning quarterly estimated payments so you don't get an underpayment penalty.
- Comparing freelance income vs. a W-2 job offer on real take-home terms.
- Sizing how much to contribute to a Solo 401k or SEP-IRA before year-end.

More questions answered
Why is my take-home so much lower than a W-2 at the same gross?
Three big drags: (1) you pay both halves of FICA (15.3% vs 7.65% for W-2); (2) you fund your own health insurance and retirement; (3) you have no employer-paid benefits like PTO. A useful rule of thumb: 1099 take-home is roughly 70–80% of an equivalent W-2 salary after all costs.
Should I form an LLC or S-corp to save on taxes?
LLC alone gives you no tax savings — single-member LLCs are taxed identically to sole proprietors. The savings come from electing S-corp status, which can reduce SE tax once your net income consistently clears ~$80–100k. Use the LLC vs S-corp calculator for the breakeven math.
How much should I set aside for taxes from each invoice?
Default rule of thumb: 25–30% of every invoice into a separate savings account. Bump to 35% if you're in a high-tax state or above the 24% federal bracket. Adjust after your first full year when you have a real effective rate.

FAQ
How much should a freelancer withhold for taxes?
Rule of thumb: set aside 25–35% of every invoice into a separate tax account. The exact rate depends on bracket and state — use this calculator to dial in the percentage. For high-income freelancers in CA/NY, 40%+ is realistic.
Do freelancers pay more tax than W-2 employees?
Yes, on equivalent gross — primarily because of the 7.65% employer-side FICA you absorb as 'self-employment tax'. But freelancers have access to far bigger pre-tax retirement contributions (Solo 401(k) up to ~$70k vs $23k for W-2 401(k)) and broader business deductions, which typically reverse the gap above ~$120k gross.
What's the standard deduction for 1099 income?
1099 income flows to Schedule C; you take the standard deduction (or itemize) on the 1040 just like W-2 income. The 'standard deduction' for 2026 is approximately $15,000 single / $30,000 MFJ. Business expenses on Schedule C are separate and reduce SE tax too.
Does this calculator handle S-corp salary + distribution math?
No — this tool models pure 1099/Schedule C income. For S-corp comparison, use our LLC vs S-corp tax calculator linked below, which models reasonable salary, FICA on salary only, and distribution treatment.
