AI Analysis
Why freelancers pay more tax than W-2 employees
When you work a regular W-2 job, your employer pays half your Social Security and Medicare contributions — 7.65% comes out of your paycheck and 7.65% comes from the company's pocket. As a freelancer or independent contractor, you're both the employee and the employer. You owe the full 15.3%— that's called self-employment tax, and it's on top of regular federal and state income tax.
On 2026 numbers: 12.4% of your net earnings goes to Social Security (capped at the wage base), and 2.9% goes to Medicare with no cap. The IRS gives you a small break — your SE tax is calculated on 92.35% of your net profit (not 100%), and half of the SE tax you owe is deductible from your federal income tax.
What counts as a deductible business expense
Almost anything you spend that's ordinary and necessary for your work: home office (a percentage of rent and utilities based on dedicated workspace square footage), software subscriptions, professional memberships, business mileage at the IRS standard rate, health insurance premiums (if self-employed full-time), continuing education, and equipment over $2,500 (which gets depreciated). Tracking these obsessively is the difference between a brutal tax bill and a manageable one.
The 20% QBI deduction (Section 199A)
Qualified Business Income (QBI) lets most self-employed people deduct an additional 20% of their net business income from their federal taxable income. It's a huge break — on $80k of net profit, that's a $16k deduction. But: the deduction phases out for higher earners (over roughly $201k single / $402k married filing jointly in 2026), and for "specified service businesses" like consulting, law, and medicine, it phases out entirely above the threshold. Our calculator applies the simplified 20% below the threshold and tapers it above; consult a CPA for exact figures if you're close to the phase-out.
Quarterly estimated taxes — pay 4 times a year, not once
The IRS expects to be paid as you earn — not all at once on April 15. If you owe more than $1,000 in tax for the year, you're required to make quarterly estimated payments by April 15, June 15, September 15, and January 15. Miss them and you'll owe an underpayment penalty (currently around 8% APR on the unpaid amount). Our calculator divides your total tax by 4 — that's your quarterly payment.

Frequently asked questions
Do I have to pay self-employment tax if I have a regular job too?
Yes — but only on your 1099 income. Your W-2 wages already had FICA withheld. If your W-2 income is high enough to hit the Social Security wage base ($184,500 in 2026), the SE Social Security portion of your 1099 income may be reduced or eliminated; Medicare still applies on every dollar.
Can I deduct my health insurance as a freelancer?
Yes. Self-employed health insurance premiums (for you, your spouse, and dependents) are deductible above the line — meaning you don't need to itemize. This calculator doesn't include that input yet, but it's a meaningful deduction.
What if I have an LLC or S-Corp?
A single-member LLC is taxed identically to a sole proprietor — same SE tax, same forms. An S-Corp election changes the math significantly: you pay yourself a 'reasonable salary' (W-2) and take the rest as distributions that aren't subject to SE tax. This calculator assumes sole proprietor / single-member LLC.
Why is my effective tax rate so high?
Because the 15.3% SE tax stacks on top of regular federal and state tax. A freelancer earning $60k in California easily pays a higher effective rate than a W-2 employee earning the same. The QBI deduction softens the blow, but the bottom line is the trade-off for the freedom of self-employment is a heftier tax bill.
