Enter every income source. See your total tax, quarterly payments, effective rate, and where every dollar goes, in one view.
The problem: Nearly one-third of the US workforce earns independent income, but every existing tax calculator handles only one source at a time. Freelance calculators ignore gig income. Reseller profit calculators stop at platform fees. Nobody connects the full pipeline: what you earned → minus fees → minus expenses → what you actually owe → what you should set aside quarterly.
This tool gives you: the complete picture. Toggle on every income source, freelance, gig, resale, crypto, W-2, and see your total tax, quarterly payment amount, effective rate, take-home, and where every dollar goes. The first free multi-source tax calculator for independent earners.

Disclaimer: This calculator provides estimates for educational purposes only. It is not tax, legal, or financial advice. Calculations use simplified models, actual liability may differ due to AMT, NIIT, itemized deductions, tax credits, and other factors. State tax calculations use 2026 approximations and may not reflect all local taxes or surcharges. Always consult a qualified tax professional for advice specific to your situation.
The Income-to-Tax Pipeline aggregates up to five income sources (freelance 1099, gig platform, reselling, crypto gains, and W-2 employment) into a single unified tax calculation. It starts by computing your total net self-employment income after deducting business expenses and mileage (at the 2026 IRS standard rate of $0.70/mile). Self-employment tax is calculated at 15.3% on 92.35% of net SE income per Schedule SE, with the Social Security portion capped at the $178,200 wage base.
The tool then computes your adjusted gross income by subtracting the above-the-line deduction for half of SE tax, applies the standard deduction for your filing status, and calculates the Section 199A QBI deduction on qualifying business income. Federal income tax is computed using 2026 marginal brackets, and state income tax uses state-specific approximations for all 50 states plus DC. Your quarterly estimated payment is the total remaining tax (after subtracting any W-2 withholding) divided by four, matching the IRS Form 1040-ES safe harbor method.
Priya works a W-2 day job earning $55,000 per year with $8,000 already withheld in federal taxes. On the side, she freelances as a UX consultant earning $30,000 with $4,000 in business expenses. She also drives for DoorDash, bringing in $12,000 with $2,000 in expenses and 8,000 miles driven (a $5,600 mileage deduction). She files as single in Illinois.
The pipeline combines all sources: $55,000 W-2 plus $26,000 net freelance plus $4,400 net gig income equals $85,400 in total gross. After the SE tax deduction, standard deduction, and QBI deduction, her taxable income lands around $54,200. Total tax comes to approximately $17,800, including $4,630 in self-employment tax, $6,350 in federal income tax, and $2,680 in Illinois state tax. After subtracting her $8,000 W-2 withholding, she owes about $9,800 more, which breaks down to roughly $2,450 per quarter. Without this combined view, Priya might have missed the SE tax on her gig income entirely.
Run this calculator at the beginning of each quarter before making your estimated tax payment to the IRS. It is especially important if you have multiple income streams, since each source interacts with the others through your marginal tax bracket and the Social Security wage base cap. Use it after any significant income change: starting a side gig, losing a W-2 job, or adding crypto gains to your portfolio. You should also run it in December to plan for year-end and decide whether to accelerate expenses or defer income into the next year. The quarterly payment output links directly to the IRS Direct Pay portal so you can submit immediately.
Your W-2 withholding only covers the tax on your W-2 wages. Any additional income from freelancing, gig work, reselling, or crypto is not withheld for, so you owe taxes on it separately. Additionally, your side income may push you into a higher marginal tax bracket, meaning even some of your W-2 income is effectively under-withheld. The quarterly estimated payment amount this tool calculates covers that gap.
The IRS allows you to deduct $0.70 per business mile driven in 2026. This covers gas, insurance, depreciation, and maintenance in a single rate. For gig drivers (Uber, DoorDash, Instacart), miles driven while on a delivery or ride count. Miles commuting to a regular workplace do not. The mileage deduction reduces your net self-employment income, which lowers both your income tax and your self-employment tax. Keep a log or use a mileage tracking app for documentation.
The Qualified Business Income (QBI) deduction under Section 199A lets eligible self-employed filers deduct up to 20% of their qualified business income from taxable income. Most freelancers, gig workers, and resellers with taxable income under the phase-out threshold ($191,950 for single filers in 2026) qualify for the full deduction. Certain specified service trades (law, accounting, consulting, health) face limitations above the threshold. This tool automatically calculates and applies the QBI deduction when applicable.
Crypto gains from selling, swapping, or spending cryptocurrency are taxed as capital gains. Short-term gains (assets held less than one year) are taxed at your ordinary income tax rate. Long-term gains (held over one year) benefit from lower capital gains rates of 0%, 15%, or 20% depending on your income. This calculator treats crypto gains as ordinary income for simplicity, which provides a conservative (higher) estimate. Consult a tax professional for precise long-term capital gains treatment.
The W-2 equivalent is the gross salary a traditional employee would need to earn to take home the same amount you do from your combined independent income. It adds back costs that employers cover for W-2 workers but that you pay out of pocket: the employer half of FICA (7.65%), health insurance premiums, and the value of paid time off. This number helps you benchmark your total independent earnings against salaried job postings in your field, giving you a fair comparison when evaluating whether the self-employed path is financially competitive.
