Results recalculate instantly on every keystroke. Nothing you type is transmitted.
What this result does not account for
- Results are a model, not a quotation — an institution's own figures govern.
- Every input is an assumption; change one and the answer changes with it.
- Rounding is applied only at the display layer, so totals may differ by a cent from a statement that rounds each line.
In short: On $120,000 of revenue with $18,000 of expenses, total federal tax is $23,579.27 — 23.12% of profit but only 19.65% of revenue, so set aside roughly a fifth of every invoice. A further $1,000 of deductible spending saves $304.86, meaning it truly costs you $695.14.
Formula
The set-aside is deliberately expressed against revenue rather than profit, because revenue is what actually arrives in your bank account when an invoice is paid.
Worked Example
- Reduce revenue to profit. $120,000 of revenue less $18,000 of expenses is $102,000 of net profit.
- Apply self-employment tax. Only 92.35% of profit is subject, giving $14,412.14 — half of which is deductible against income tax.
- Take the QBI deduction. 20% of qualified business income, capped by taxable income, gives $16,038.79 off the taxable base.
- Compute income tax. $64,155.14 of taxable income produces $9,167.13 of federal tax.
- Express it against revenue. $23,579.27 of total tax is 23.12% of profit but 19.65% of revenue — the number that matters when an invoice lands.
Freelancers routinely under-reserve because they think in terms of their tax bracket. The 22% bracket is irrelevant here: what matters is that SE tax, income tax and the QBI deduction all move together, making the true marginal value of a deduction 30.49%.
Strengths & Limits Of This Model
Where this engine is strong
- Runs entirely in your browser — no figure you type is transmitted or stored.
- Shows the full working, so every number can be traced and challenged.
- Free, unmetered and free of affiliate incentives.
Where it stops
- Generalised assumptions cannot capture every individual circumstance.
- Jurisdiction-specific rules and mid-year changes may not be reflected.
- A model output is not a substitute for a professional review of your position.
Practical Use Cases
Setting up a tax reserve account
Move 19.65% of every payment into a separate account the day it clears. That single habit removes the April cash-flow problem entirely.
Deciding whether to buy equipment before year end
A $1,000 purchase costs $695.14 after relief. That is the number to weigh, not the sticker price.
Pricing a new engagement
To keep $1,000 after tax you must invoice $1,244.53. Build the gross-up into your rate card rather than discovering it at filing.
Making quarterly estimated payments

Methodology & Editorial Standards
The engine computes self-employment tax on 92.35% of net profit, deducts the employer-half against income tax, applies the standard deduction and a 20% QBI deduction capped by taxable income, then taxes the remainder on 2024 single-filer brackets. The QBI deduction was made permanent at 20% by the One Big Beautiful Bill Act. The marginal-deduction figure is computed by re-running the entire calculation at a profit $1,000 lower, so it captures the SE tax, income tax and QBI interactions together rather than approximating with a bracket rate. Retirement contributions are treated as an above-the-line adjustment, which matches a SEP or solo 401(k) employer contribution but not a Roth. State tax is a flat rate on adjusted gross income and ignores state-specific deductions entirely. The engine implements the standard published formula for this calculation. Inputs are validated for domain and sign before evaluation, and any undefined case returns an em-dash rather than a spurious value.
Computation runs in IEEE-754 double precision at full internal precision; rounding to two decimal places occurs strictly at the display layer, so no cumulative drift enters the result. All monetary outputs use accounting presentation — grouped thousands, two decimals, negatives in parentheses — so figures can be transcribed directly into a model or working paper. Division-by-zero and out-of-domain inputs return an em-dash rather than a misleading number.
This engine was reconciled against an independent reference implementation and hand-verified for the worked example above before release. Our full five-stage review process is published on the About Us page.

Freelance Tax Calculator — 20 Expert FAQs
20 analyst-written answers to the questions practitioners actually ask — optimised for voice and answer-engine retrieval.
How much should I set aside for taxes as a freelancer?
About 19.65% of revenue at this income level — roughly a fifth of every invoice. Setting aside a percentage of revenue rather than profit is what prevents an April shortfall.
Why is my freelance tax rate higher than my bracket?
Because self-employment tax sits on top of income tax. You pay both halves of Social Security and Medicare, which a salaried employee splits with an employer.
What percentage of profit goes to tax?
23.12% of profit here, against 19.65% of revenue. The two figures differ because expenses reduce profit but not the revenue that hits your account.
How much does a business expense really save me?
$304.86 per $1,000 here, or 30.49%. That is far more than the 12% bracket suggests, because the deduction reduces SE tax and income tax at once.
Do I pay tax on revenue or profit?
Profit. But you should reserve against revenue, because that is the money arriving, and expenses are paid out of the same account.
What is the QBI deduction for freelancers?
A deduction of 20% of qualified business income, worth $16,038.79 here. It was made permanent at 20% by the One Big Beautiful Bill Act.
Can I deduct a home office?
Yes, either by the simplified $5 per square foot method up to 300 square feet, or by apportioning actual home costs by the business-use percentage.
Do I need to make quarterly payments?
Generally yes, once you expect to owe $1,000 or more. Missing them triggers an underpayment penalty even if you pay in full by April.
How much must I invoice to keep $1,000?
$1,244.53 at this income level. Build that gross-up into your rates rather than discovering it when you file.
Does a retirement contribution reduce freelance tax?
A SEP or solo 401(k) contribution reduces income tax but not self-employment tax, since SE tax is computed before that deduction.
Are health insurance premiums deductible?
Self-employed health insurance is deductible above the line against income tax, though like retirement contributions it does not reduce SE tax.
What if my income varies month to month?
Reserve the same percentage of each payment rather than a fixed amount. The percentage self-adjusts to whatever you actually earn.
Do I pay self-employment tax on all my profit?
On 92.35% of it. The 7.65% reduction represents the employer half that a business would have deducted before computing its own tax.
Should I incorporate to reduce freelance tax?
Possibly above roughly $60,000 of profit, where an S-corp election starts to save more payroll tax than the extra compliance costs.
What records do I need to keep?
Every receipt supporting a deduction, plus a clear separation between business and personal accounts. Mixed accounts are the fastest route to losing deductions on examination.
Is this freelance tax calculator free to use?
Yes. It is free, requires no account, and has no usage limits. ApexConverter is funded by contextual advertising, never by selling user data.
Is my data sent to a server?
No. The engine runs as Vanilla JavaScript inside your browser under our Zero-Server Client-Side Execution model. Your figures are computed locally and are never transmitted, logged, or stored.
How accurate is this calculator?
It applies the standard closed-form formula in IEEE-754 double precision, rounding only at the display layer. The engine is reconciled against an independent reference implementation before release.
Does it work on mobile?
Yes. The interface is mobile-first with numeric keypad hints and is tested down to a 320-pixel viewport with no horizontal scrolling.
Can I use it offline?
Largely, yes. Because computation is client-side, the page continues to calculate without a network connection once it has loaded.
