Freelance Taxes: How Much to Set Aside
August 4, 2026
Most freelancers should set aside somewhere between 20% and 40% of each payment for taxes — and the reason that range is so wide is that the right number depends on three things the popular advice ignores: your federal marginal rate, your state, and how much of the payment disappears into deductible business costs. Someone at the 12% bracket in Texas with heavy material costs and someone at 24% in California with none are both freelancers, and their correct set-aside differs by more than twenty percentage points.
This is the arithmetic behind that, and how to turn it into a habit that takes ten seconds per invoice.
Why doesn’t the 30% rule work?
The 30% rule works for exactly one person: a single filer at the 12% federal bracket, in a state with no income tax, with almost no deductible expenses. Everyone else is either over-saving — which quietly starves the business of cash — or under-saving, which is the expensive direction.
The rule survives because it is memorable and because being wrong in the safe direction is invisible. Nobody notices that they set aside $4,000 more than they needed; they just feel poor all year. The people who notice are the ones who set aside 30% while sitting in the 24% bracket in a 5% state, and who find in April that the real figure was closer to 40%.
What actually goes into the number?
Three separate taxes stack on freelance income, and they stack in a specific order that changes the total.
Self-employment tax comes first. It is 15.3% — 12.4% Social Security plus 2.9% Medicare — charged on 92.35% of your net profit, which works out to roughly 14.1% of profit. Employees split this with an employer; you are both halves. The Social Security portion stops applying above the annual wage base, so very high earners pay a lower effective rate on income above it.
Federal income tax comes next, and this is where the marginal rate matters. The seven federal rates for 2026 are 10%, 12%, 22%, 24%, 32%, 35% and 37%. You get to deduct half your self-employment tax before this is calculated, which is a small mercy most rules of thumb skip.
State and local income tax comes last, and ranges from zero to over 10% depending on where you sit. Nine states levy no income tax on wages at all.
| Situation | Net profit share | Roughly what to set aside |
|---|---|---|
| 12% federal, no state tax, no expenses | 100% of payment | ~25% |
| 22% federal, 5% state, no expenses | 100% of payment | ~40% |
| 22% federal, 5% state, 40% costs | 60% of payment | ~24% of the gross payment |
| 24% federal, no state tax, 20% costs | 80% of payment | ~29% of the gross payment |
The last two rows are the point. Two freelancers with identical tax rates can need very different set-aside percentages purely because one of them buys materials.
When are freelance taxes actually due?
If you expect to owe $1,000 or more when you file, the IRS expects estimated payments four times a year, not once in April. The payment periods end 31 March, 31 May, 31 August and 31 December, with payments due 15 April, 15 June, 15 September and 15 January.
That schedule is the real reason a tax pot matters. Tax on money you received in February is due in April of the same year, long before the annual return exists. A pot that gets raided in March is not a pot.
How do you avoid an underpayment penalty?
The IRS provides a safe harbor: pay at least 90% of what you end up owing this year, or 100% of what you owed last year, whichever is smaller. If your adjusted gross income last year was over $150,000 — $75,000 if married filing separately — the prior-year figure rises to 110%.
The prior-year safe harbor is the useful one for freelancers with unpredictable income, because it is a known number in January rather than a guess about a year that hasn’t happened. Hit it, and a good year cannot generate a penalty even if your final bill is much larger.
What to do the day a client pays you
The habit that works is small and immediate: when the money lands, calculate the set-aside, move it to a separate account, and log it. Not weekly, not monthly — the same session, because the transfer is the thing that makes the number real.
Our free Freelance Tax Set-Aside Calculator does the arithmetic from your own rates, then keeps a running log of every payment and a monthly chart of what you have set aside. It runs entirely in your browser: your income figures are never uploaded, because a website has no business knowing what you earn.
The log has a second use most people don’t expect. After six months it is the clearest evidence you have of what your year actually looks like — which invoices came in, how large they were, how much of your gross income was never yours. That is exactly the information you need when deciding whether your rates should go up.
Common questions
Should I set aside from gross or net income?
Calculate from net — gross payment minus the deductible costs of doing that work — but express the answer as a percentage of the gross payment, because gross is what actually arrives in your account. That is the number you can act on without doing a second calculation.
What if my income varies wildly month to month?
Set aside a percentage of each payment rather than a fixed monthly amount. A percentage self-adjusts: a quiet month moves less, a huge month moves more. If your income is genuinely unpredictable, the prior-year safe harbor is your friend, because it fixes the target in advance.
Do I still need to do this if freelancing is a side hustle?
Yes, if you expect to owe $1,000 or more overall. Self-employment tax applies to freelance profit regardless of whether you also have a W-2 job, though extra withholding from the day job is an alternative to quarterly payments for some people. Our Side Hustle Hourly Rate Calculator is worth a look if you’re still working out whether the side work pays what you think it does.
Is this tax advice?
No. This is arithmetic and publicly available IRS rules, written to stop you spending money that was never yours. Rates, thresholds and deadlines change, and your situation may include credits, deductions or other income that changes the answer. Confirm the real figure with a tax professional before you file.
