Freelancing means nobody withholds tax for you. The money lands in your account looking like yours, and some of it isn’t. This calculator estimates your 2026 federal tax bill and tells you what percentage of each client payment to hold back, so April is boring instead of alarming.
It handles the two taxes self-employed people pay — self-employment tax and federal income tax — and shows the arithmetic behind both. Every figure it uses comes from an IRS or Social Security Administration document you can open and check.
This is an estimate for planning, not tax advice. It does not replace a qualified tax professional, and your actual liability may differ because of circumstances this tool does not model. It covers federal tax only. Not affiliated with or endorsed by the IRS.
How the Self-Employed Tax Calculator Works
Give it one number and it will work. Enter your net business profit — what’s left after your business expenses, not what your clients paid you — and you’ll get an estimate. Everything else refines it.
Behind the scenes it follows the same sequence as an actual tax return:
- Schedule C establishes your net business profit.
- Schedule SE applies self-employment tax to 92.35% of that profit.
- Schedule 1 subtracts your adjustments — half your self-employment tax, health insurance premiums, retirement contributions — to reach adjusted gross income.
- Form 1040 subtracts your standard or itemized deduction and your Qualified Business Income deduction to reach taxable income, then applies the 2026 rate schedule.
- Schedule 8812 applies the Child Tax Credit if you have qualifying dependents.
- Form 1040-ES turns what’s left into four quarterly payments.
Open any of the “how this was worked out” panels in the results and you’ll see each step with its own line, its own arithmetic, and a plain-English note explaining why it’s there.
What makes this different from a rate-times-income calculator. Three things that simpler tools get wrong, and that change the answer materially:
- The Social Security wage base is shared. If you have W-2 wages alongside freelance income, those wages fill the $184,500 Social Security cap first. Only the remaining room is charged on your self-employment earnings. Calculators that ignore this overstate the bill for anyone with a day job.
- The QBI deduction is capped by taxable income, not just by business income. It’s the lesser of 20% of qualified business income and 20% of your taxable income. For most freelancers taking the standard deduction, the second limit is the one that binds — which is why the deduction is usually smaller than “20% of profit.”
- Above the QBI threshold, a solo freelancer with no payroll loses almost all of it. The deduction is limited by W-2 wages your business pays. Pay none, and above roughly $277,000 of taxable income you’re left with the $400 statutory minimum. That’s a real cliff and most calculators don’t show it.

What Taxes Do Self-Employed People Pay?
Two separate federal taxes, calculated on different bases, stacked on top of each other. Understanding that they’re separate is most of the battle.
Self-employment tax
This is Social Security and Medicare. An employee pays 7.65% and their employer pays a matching 7.65%. When you work for yourself, you are both, so you pay the full 15.3%.
It applies from the very first dollar of profit — there is no standard deduction against it, no personal allowance, nothing. A freelancer with $30,000 of profit and no other income pays roughly $4,239 of self-employment tax and only about $942 of income tax. At that income level, self-employment tax is more than four times the income tax bill. This is the single biggest surprise for people who’ve only ever been employees.
Federal income tax
Ordinary income tax on your taxable income, at the same 2026 rates everyone else pays: 10%, 12%, 22%, 24%, 32%, 35% and 37%. Your standard deduction, your QBI deduction, and any above-the-line adjustments all reduce the amount this applies to.
The two together
| Net profit (single filer, no dependents) | Self-employment tax | Income tax | Total federal | Effective rate |
|---|---|---|---|---|
| $25,000 | $3,532 | $571 | $4,103 | 16.4% |
| $30,000 | $4,239 | $942 | $5,181 | 17.3% |
| $50,000 | $7,065 | $2,667 | $9,732 | 19.5% |
| $75,000 | $10,597 | $4,898 | $15,495 | 20.7% |
| $100,000 | $14,130 | $8,235 | $22,365 | 22.4% |
| $125,000 | $17,662 | $12,324 | $29,986 | 24.0% |
| $150,000 | $21,194 | $16,413 | $37,608 | 25.1% |
| $200,000 | $28,234 | $25,196 | $53,431 | 26.7% |
| $250,000 | $29,573 | $36,509 | $66,360 | 26.5% |
Two things worth noticing. Self-employment tax dominates until around $75,000, then income tax overtakes it as more profit lands in the 22% and 24% brackets. And the effective rate falls slightly between $200,000 and $250,000 — that’s the Social Security wage base cutting in, after which further profit only attracts the 2.9% Medicare portion.
What isn’t in these numbers
State income tax. Forty-one states and the District of Columbia tax earned income; nine don’t. If you’re in California, New York, or Oregon, add a meaningful amount on top. If you’re in Texas, Florida, Washington, Nevada, Tennessee, South Dakota, Wyoming, Alaska, or New Hampshire, the federal figure is close to your whole income tax picture. The calculator tells you which situation you’re in when you pick your state, but it does not estimate the state amount, because doing that accurately for 42 jurisdictions is a different project.
How Much Should a Freelancer Set Aside for Taxes?
You’ll see “set aside 30%” repeated all over the internet. For most freelancers it’s too much, and for some it’s not enough. The right number depends on your profit, your filing status, your dependents, and whether you have a job alongside the freelance work.
Here is what the math actually produces:
Single, no dependents
| Net profit | Set aside | Monthly | Per $1,000 invoiced |
|---|---|---|---|
| $25,000 | 16.4% | $342 | $164 |
| $50,000 | 19.5% | $811 | $195 |
| $75,000 | 20.7% | $1,291 | $207 |
| $100,000 | 22.4% | $1,864 | $224 |
| $150,000 | 25.1% | $3,134 | $251 |
| $200,000 | 26.7% | $4,453 | $267 |
Married filing jointly, two children, spouse has no income
| Net profit | Set aside | Total federal tax |
|---|---|---|
| $50,000 | 7.6% | $3,806 |
| $75,000 | 12.4% | $9,301 |
| $100,000 | 15.1% | $15,064 |
| $150,000 | 17.7% | $26,590 |
| $200,000 | 20.2% | $40,306 |
Head of household, one child
| Net profit | Set aside | Total federal tax |
|---|---|---|
| $40,000 | 11.2% | $4,494 |
| $60,000 | 14.9% | $8,958 |
| $80,000 | 17.0% | $13,569 |
| $120,000 | 19.2% | $23,034 |
The spread is enormous — from 7.6% to 26.7% across the same tool. A married freelancer with two children earning $50,000 who sets aside 30% is starving their own household of nearly $11,000 a year for no reason. A single freelancer at $200,000 who sets aside 25% is going to be short.
When 30% is roughly right
If you have a W-2 job alongside your freelance work, your freelance income stacks on top of your wages, so it’s taxed at your highest rate rather than an average one. It also attracts self-employment tax that your salary doesn’t:
| W-2 wages ($60,000, $7,000 withheld) plus freelance profit of | Balance after withholding | Set aside from freelance |
|---|---|---|
| $10,000 | $419 | 4.2% |
| $20,000 | $3,467 | 17.3% |
| $40,000 | $9,564 | 23.9% |
| $60,000 | $15,662 | 26.1% |
Notice how sharply this climbs. That’s the stacking effect. If your day job’s withholding already covers its own tax, the freelance side has to carry its full marginal cost.
Add a cushion, but choose it deliberately
The calculator offers a +10% or +20% cushion on top of the estimate. Reasons to take one: your income is lumpy and hard to forecast, you’re in your first year and don’t know your expenses yet, or you live somewhere with state income tax the tool doesn’t estimate. Reasons not to: you’re already saving diligently and a bigger cushion just means lending the government money interest-free.
A practical habit that beats any percentage: open a second checking account, move the set-aside percentage across the moment each client payment clears, and never touch it. The percentage matters less than the transfer being automatic.
How Self-Employment Tax Is Calculated
The formula has one step that surprises people, so it’s worth walking through properly.
Step 1 — Start with net profit, not revenue
Self-employment tax applies to your net business profit: revenue minus your ordinary and necessary business expenses. Every legitimate deduction you claim reduces both your income tax and your self-employment tax, which is why bookkeeping pays for itself.
Step 2 — Multiply by 92.35%
Only 92.35% of your net profit is subject to the tax. This isn’t arbitrary. An employee never pays tax on their employer’s half of FICA, so the law reduces your base by 7.65% to put you on comparable footing. 100% − 7.65% = 92.35%.
The result is your net earnings from self-employment. If it comes to less than $400, no self-employment tax is due at all.
Step 3 — Apply the two rates
- Social Security: 12.4%, but only on earnings up to the wage base, which is $184,500 for 2026. Any W-2 wages you have use up that allowance first.
- Medicare: 2.9%, on everything, with no cap.
Together, 15.3% — until you cross the wage base, at which point your marginal rate drops to 2.9%.
Step 4 — Deduct half of it
You can deduct one-half of your self-employment tax as an above-the-line adjustment. This reduces your income tax, not your self-employment tax. It’s a partial offset, not a refund.
Worked example: $80,000 of net profit
| Step | Calculation | Amount |
|---|---|---|
| Net business profit | Schedule C bottom line | $80,000 |
| Net earnings from self-employment | $80,000 × 92.35% | $73,880 |
| Social Security portion | 12.4% × $73,880 | $9,161 |
| Medicare portion | 2.9% × $73,880 | $2,143 |
| Self-employment tax | $11,304 | |
| Deduction for one-half | $11,304 ÷ 2 | $5,652 |
That $5,652 comes off income before the income tax calculation. Continuing:
| Step | Amount |
|---|---|
| Adjusted gross income ($80,000 − $5,652) | $74,348 |
| Less standard deduction (single, 2026) | −$16,100 |
| Less QBI deduction (20% of taxable income, the binding limit) | −$11,650 |
| Taxable income | $46,599 |
| Federal income tax | $5,344 |
| Plus self-employment tax | $11,304 |
| Total federal tax | $16,648 |
| Effective rate on $80,000 | 20.8% |
The Additional Medicare Tax
Once your combined wages and self-employment earnings pass $200,000 (single or head of household), $250,000 (married filing jointly) or $125,000 (married filing separately), an extra 0.9% applies to the excess. These thresholds are set in statute and are not adjusted for inflation, so more people cross them every year.
What Can Self-Employed People Deduct?
There are three different kinds of deduction, and confusing them is the most common source of wrong estimates.
Business expenses — the most valuable kind
These come off on Schedule C, before anything else. They reduce your net profit, which means they reduce both your self-employment tax and your income tax. A dollar of legitimate business expense is worth far more than a dollar of any other deduction.
Common ones for freelancers: software subscriptions, hardware, home office (either the simplified square-footage method or actual expenses), business mileage, professional insurance, contractor and subcontractor payments, business bank and payment-processor fees, advertising, professional development and courses, industry memberships, accounting and legal fees, business phone and internet apportioned to business use.
The test in IRC §162 is that the expense must be ordinary (common in your line of work) and necessary (helpful and appropriate). Records matter more than the category.
Above-the-line adjustments — reduce income tax only
These come off after your net profit is set, so they lower your income tax but leave your self-employment tax untouched:
- One-half of your self-employment tax — automatic, no action needed.
- Self-employed health insurance premiums — medical, dental and qualified long-term care for you and your family, limited to your net self-employment earnings.
- Retirement contributions — a SEP-IRA lets you contribute roughly 20% of your net earnings after the half-SE-tax deduction; a solo 401(k) can allow more because you make both employee and employer contributions.
- HSA contributions — $4,400 for self-only coverage or $8,750 for family in 2026, plus $1,000 if you’re 55 or over, provided you have a qualifying high-deductible plan.
- Traditional IRA contributions — $7,500 in 2026 ($8,600 if you’re 50 or over), though the deduction phases out if you’re also covered by a workplace retirement plan.
- Student loan interest — up to $2,500, phasing out between $85,000 and $100,000 of income for single filers and $175,000 to $205,000 for joint filers.
The standard deduction and QBI — reduce taxable income
The standard deduction for 2026 is $16,100 for single and married-filing-separately filers, $32,200 for married filing jointly, and $24,150 for head of household. Take it unless your itemized deductions come to more.
The Qualified Business Income deduction under §199A gives you up to 20% of your qualified business income. The One Big Beautiful Bill Act made it permanent, widened the phase-in ranges for 2026, and added a $400 minimum for active business owners with at least $1,000 of qualified income. Two limits catch freelancers out: the deduction can’t exceed 20% of your taxable income, and above $201,750 of taxable income ($403,500 if filing jointly) it’s restricted by the W-2 wages your business pays — which for a solo operator is usually zero.
What buying something actually costs you
A deduction is a discount, not a rebate. Spend $5,000 on something deductible when you’re in the 12% bracket with self-employment tax on top, and you’ll save roughly $1,300 — so the thing still costs you around $3,700. The calculator’s expense scenario tool works this out for your specific numbers. It’s genuinely useful for deciding whether to buy the laptop in December or January. It is not a reason to buy a laptop you don’t need.
Quarterly Estimated Tax Payments
Nobody withholds tax from a client payment, so the IRS asks you to pay through the year instead of all at once.
Who has to pay
Broadly, anyone expecting to owe $1,000 or more in federal tax after subtracting withholding and refundable credits. Most freelancers earning more than about $6,000 of profit will clear that bar.
2026 due dates
| Payment | Due | Covers |
|---|---|---|
| Q1 | April 15, 2026 | January 1 – March 31 |
| Q2 | June 15, 2026 | April 1 – May 31 |
| Q3 | September 15, 2026 | June 1 – August 31 |
| Q4 | January 15, 2027 | September 1 – December 31 |
They are not evenly spaced. Q2 covers two months, Q3 covers three, and Q4 lands in the following January. Diarize them.
The safe harbor — the most useful rule most freelancers don’t know
You avoid an underpayment penalty if your payments during the year reach the smaller of:
- 90% of your current year’s total tax, or
- 100% of last year’s total tax — or 110% if last year’s adjusted gross income was above $150,000 ($75,000 if married filing separately).
The second option is the useful one. It’s a fixed, known number from a return you’ve already filed. If you’re having a much better year than last year, paying 100% or 110% of last year’s tax protects you from any penalty even though you’ll still owe a balance in April. You get to keep the difference in your own account until then.
Enter last year’s figures in the calculator’s Payments and safe harbor section and it will tell you which of the two targets is lower.
Uneven income
If your income arrives in bursts — a large project in Q3, nothing in Q1 — equal quarterly payments can overstate what you owe early in the year. The annualized income installment method in IRS Publication 505 lets you match payments to when you actually earned. It’s more work, and it’s worth it if your income is genuinely lumpy.
How to pay
IRS Direct Pay from a bank account, EFTPS, your IRS online account, or a card (which carries a fee). Direct Pay is free and takes about two minutes.
Frequently Asked Questions
How much should a freelancer set aside for taxes?
Between roughly 15% and 27% of net profit for most freelancers, depending on income, filing status and dependents. A single freelancer with $50,000 of profit should set aside about 19.5%; the same profit for a married filer with two children works out closer to 7.6%. The common “30%” advice is too high for most people and too low for higher earners with a W-2 job alongside. Use the calculator with your own numbers rather than a rule of thumb, and remember to add something for state tax if your state has one.
How is self-employment tax calculated?
Multiply your net business profit by 92.35% to get your net earnings from self-employment. Apply 12.4% for Social Security on earnings up to $184,500 in 2026, and 2.9% for Medicare on all of it. That’s 15.3% combined below the wage base. You then deduct half the resulting tax from your income when calculating income tax. On $80,000 of profit, that’s $11,304 of self-employment tax with $5,652 deductible.
Do freelancers pay income tax and self-employment tax?
Yes, both, and they’re calculated separately. Self-employment tax funds Social Security and Medicare and applies from your first dollar of profit. Income tax applies to your taxable income after your standard deduction, QBI deduction and other adjustments. At lower incomes self-employment tax is usually the larger of the two; the balance flips somewhere around $75,000 of profit for a single filer.
How much tax do I pay on $50,000 of self-employed income?
For a single filer with no dependents taking the standard deduction, roughly $9,732 in 2026 — about $7,065 of self-employment tax and $2,667 of income tax, an effective rate of 19.5%. Married filing jointly with two children, the same $50,000 produces about $3,806 because the larger standard deduction and the Child Tax Credit absorb the income tax entirely and the refundable portion offsets part of the self-employment tax. State tax would be additional.
Do 1099 workers pay more taxes than employees?
On the same gross figure, yes — a 1099 worker pays the full 15.3% self-employment tax where an employee pays 7.65% and their employer covers the rest. But the comparison isn’t straightforward. Self-employed people can deduct business expenses that employees can’t, can claim the QBI deduction that wage income doesn’t qualify for, and can contribute far more to tax-advantaged retirement accounts. A contractor billing $100,000 with $20,000 of genuine business expenses is often in a comparable or better position than an employee on $80,000 — before accounting for the benefits an employer would otherwise provide.
Do freelancers have to pay quarterly taxes?
If you expect to owe $1,000 or more in federal tax after withholding and refundable credits, yes. Payments for 2026 are due April 15, June 15, September 15, and January 15, 2027. You can avoid an underpayment penalty by paying 90% of this year’s tax or 100% of last year’s (110% if last year’s income was above $150,000). If you also have a W-2 job, increasing your withholding there is an alternative — withholding counts as paid evenly across the year regardless of when it actually happened, which can retroactively fix an earlier shortfall.
What deductions can self-employed people claim?
Business expenses that are ordinary and necessary for your trade — software, hardware, home office, business mileage, professional insurance, subcontractors, advertising, professional development, accounting fees. These are the most valuable because they cut both your self-employment tax and your income tax. Separately, above-the-line adjustments including self-employed health insurance, retirement contributions, and HSA contributions reduce your income tax only. Then the standard deduction and the QBI deduction reduce taxable income.
Does this calculator include state taxes?
No. It estimates federal tax only. When you select your state it will tell you whether that state taxes earned income, but it does not calculate the amount. Nine states — Alaska, Florida, Nevada, New Hampshire, South Dakota, Tennessee, Texas, Washington and Wyoming — have no state income tax on earned income, so for residents there the federal figure is close to the complete picture. Everywhere else, budget additional funds.
Is this calculator accurate?
It’s accurate for what it models, and it’s explicit about what it doesn’t. Every 2026 parameter is taken from a primary IRS or Social Security Administration document, listed in the results with a link to the source. The calculation follows the sequence of the actual forms rather than approximating with a flat rate.
It does not model capital gains and qualified dividends at their preferential rates, the Alternative Minimum Tax, the Net Investment Income Tax, the Earned Income Tax Credit, education or childcare credits, the new deductions for tips and overtime, S-corporation elections, multi-state situations, or any state and local tax. If any of those apply to you, treat the result as a starting point and speak to a tax professional. It is an estimate for planning, not a substitute for a prepared return.
Should I become an S corporation?
Possibly, above roughly $80,000–$100,000 of consistent profit — but it’s a genuine trade-off rather than a free saving. An S corporation lets you split your income between a reasonable salary (subject to payroll tax) and distributions (which aren’t), which can reduce self-employment tax. Against that: payroll filings, a separate business return, state franchise fees, higher accounting costs, and the requirement that the salary be defensibly “reasonable.” It also reduces the earnings that count toward your future Social Security benefit. Worth modeling properly with an accountant rather than deciding from a blog post.
