Not tax advice. This guide explains commonly cited rules of thumb for planning purposes. Tax law varies by country, state and situation — confirm your actual obligations with a qualified tax professional.
The 25–30% rule and what it covers
When you work as an employee, your employer withholds income tax and pays half of your Social Security and Medicare contributions before the money reaches you. As a freelancer, you are both employer and employee — so both halves land on you. That is why the savings percentage runs so much higher than the withholding rate on a salaried paycheck.
The 25–30% rule stacks the two obligations together:
- Self-employment tax: 15.3% on net earnings — 12.4% Social Security plus 2.9% Medicare. (It applies to roughly 92.35% of net profit, and you deduct half of it when figuring income tax.)
- Income tax: 10% to 37% on taxable income after deductions — the actual rate depends on your bracket, the standard deduction and business deductions.
For a mid-range freelancer these combine to roughly 25–30% of net profit for federal taxes. The rule has held up across freelance tax guides for years because it absorbs the two real failure modes: forgetting self-employment tax exists, and assuming your effective tax rate equals your marginal rate (a freelancer in the 22% bracket is closer to 30% effective once self-employment and state taxes are added).
When to save more — or less
The 25–30% band is a default, not a law. Adjust it to your situation:
Lower profit, no state income tax
Under roughly $40,000 of annual net profit, total federal liability often lands under 20% after the standard deduction and the half-SE-tax deduction. If you also live in a state with no income tax, 20–25% is usually enough — but keep the habit strict, because the danger at low income is not the rate, it is skipping the transfer entirely.
Most freelancers, most situations
The safe default for year one, when you have no prior tax return to anchor on. It builds in a small cushion, which beats coming up short in April. If you want precision later: take last year's total tax bill, divide by last year's gross freelance income, and use that percentage — for most freelancers it lands between 25% and 33%.
High income or high-tax state
Above roughly $100,000–$150,000 of profit, more earnings land in higher brackets and the effective rate climbs. Add state income tax — from a few percent to over 10% depending on the state — and 30–35%, sometimes 40%, is the honest number. Marketplace commissions (which compound on top of tax) push it further for platform-heavy earners.
The transfer-on-every-payment system
The percentage matters less than the timing. The system that actually works:
- Every time money hits your account, transfer your percentage to a separate savings account you do not touch. Not at month end. Not "when I remember". Every payment.
- Calculate on net, true up quarterly. Apply the percentage to each payment as it arrives (simple, automatic), then reconcile against actual net profit at each quarter end and adjust the rate if you are consistently over or under.
- Never let the reserve mix with operating funds. A tax reserve that shares an account with spending money is not a reserve — it is a hope. Separation is the entire mechanism.
The classic freelancer tax disaster is not a wrong percentage — it is December arriving with a full year of income and an empty tax account. The transfer habit fixes the behaviour; the percentage only tunes the amount. Get the habit first.
Quarterly payments without the scramble
In the US, if you expect to owe $1,000 or more for the year, you generally must pay quarterly estimated taxes — typically due in mid-April, mid-June, mid-September and mid-January. Missing them can trigger underpayment penalties even if you pay in full at year end. With the transfer system running, each quarterly payment is just a transfer out of the reserve — the money was set aside months ago, and the deadline is a calendar event, not a crisis.
Track the reserve as one of your five core freelance numbers, and fold it into the irregular-income budget as the first slice of every payment. Tax stops being a season and becomes a line item.
Frequently asked questions
What percentage of income should freelancers save for taxes?
The widely used rule is 25–30% of net profit for federal taxes in the US, rising toward 35% or more in states with income tax. The percentage stacks self-employment tax (15.3%) and income tax together. Lower earners may need less; higher earners or those in high-tax states should save more.
Do freelancers have to pay quarterly estimated taxes?
In the US, yes — if you expect to owe $1,000 or more for the year. Payments are typically due in mid-April, mid-June, mid-September and mid-January. Missing them can trigger underpayment penalties even if you pay in full at year end.
Should I save tax on gross income or net profit?
Apply your savings percentage to net profit (income minus business expenses), since tax is calculated on profit, not gross. A practical approach: transfer 25–30% of each payment to a separate reserve immediately, then true it up against your actual profit at quarter end.
What happens if I under-save for freelance taxes?
You owe the shortfall at filing time, plus possible underpayment penalties if you skipped required quarterly payments. The fix going forward is the transfer habit: a slightly wrong percentage moved every payment beats a perfect percentage moved never.
