How Much Should Freelancers Set Aside for Taxes? The 2026 Rule of Thumb (and the Real Math)

Published: May 29, 2026 · Reading time: 8 min

TL;DR: Set aside 25–30% of your net profit as a starting rule of thumb, and adjust up to 30–40% if you're a high earner or in a high-tax state. The number is high because freelancers stack three taxes: the 15.3% self-employment tax (you pay both halves), your federal income-tax bracket, and any state income tax. Save on net profit, not gross revenue — taxes are on profit, so good expense tracking lowers what you set aside. The mechanics: move your percentage into a separate account every time you're paid, make quarterly estimated payments, and use the safe-harbor rule (pay 100% of last year's tax, 110% if prior-year AGI > $150k) to avoid penalties.

"How much should I save for taxes?" is the first real question every new freelancer asks — usually right after their first big invoice clears and they realize nobody withheld anything. The honest answer is "it depends," but there's a defensible rule of thumb and a clear way to refine it. Here's both.

The Quick Answer: 25–30% of Net Profit

For most lower-to-middle-income freelancers, set aside 25–30% of your net profit — the money left after business expenses. That range is built to cover:

Stack those and a 25–30% reserve is a sound default. Two adjustments:

• Higher federal bracket or high-tax state? Lean toward 30–40%.
• Modest income in a no-income-tax state? The low-to-mid 20s may be enough.

Why the Number Is So High: Self-Employment Tax

The shock isn't income tax — it's self-employment (SE) tax. Employees split Social Security and Medicare with their employer: 7.65% each. As a freelancer, you're both halves, so you pay the full 15.3% on 92.35% of your net profit, before a dollar of income tax.

The relief: half of your SE tax is deductible above the line, which lowers your income-tax base. But the headline stands — on the same income, a freelancer owes more than a W-2 employee. Full explainer: self-employment tax explained.

Save on Net Profit, Not Gross Revenue

The single biggest mistake is saving a percentage of gross receipts. Taxes hit profit, not revenue. If you bring in $100,000 but have $30,000 of legitimate expenses, you're taxed on $70,000 — saving 30% of the full $100k needlessly locks up cash.

That's why expense tracking is tax strategy: every deduction you capture lowers the base you're saving against. See tax deductions for freelancers and the self-employed deductions people miss. The cleaner your books, the lower and more accurate your set-aside.

Deductions and QBI Pull the Number Down

Two levers shrink your taxable base:

1. Ordinary business deductions — everything on Schedule C Lines 8–30 reduces net profit directly.
2. The 20% QBI deduction — qualifying freelancers deduct up to 20% of qualified business income on top of their expenses. See the QBI deduction for freelancers.

A freelancer who tracks deductions well and qualifies for QBI can land near the bottom of the 25–30% range; one who tracks nothing and forgets QBI lands at the top — or worse, under-saves.

Worked Example

Priya freelances and nets $80,000 in profit (after $20,000 of expenses on $100,000 of revenue), single, in a state with ~5% income tax:

That's roughly 29% of her net profit — squarely in the rule-of-thumb range. Had she ignored her $20,000 in deductions, she'd have over-saved on phantom income all year.

The System: Bucket + Quarterly

Knowing the percentage is useless if the money isn't there in April. Two habits make it automatic:

1. The separate-account bucket

Every time a client pays you, immediately move 25–30% of the profit into a separate savings account you don't touch. Don't save "whatever's left" — there's never anything left. Treat the transfer as part of getting paid.

2. Quarterly estimated payments

The IRS wants the money four times a year (roughly mid-April, mid-June, mid-September, and mid-January), because no employer is withholding for you. Pay from your tax bucket. See quarterly estimated taxes: a freelancer's guide and the quarterly tax checklist for 1099 contractors. To size the payments, use the estimated tax payments calculator.

The Safe Harbor: Your Penalty Shield

You don't have to predict your tax perfectly to avoid an underpayment penalty. The safe harbor protects you if you pay in at least:

• 90% of this year's total tax, or
• 100% of last year's tax (110% if your prior-year AGI exceeded $150,000).

Hit either and the IRS can't charge an underpayment penalty even if you owe more at filing. This is the freelancer's safety net — full detail in the estimated-tax safe harbor for freelancers.

Start at 30% in your first year when you don't yet know your numbers, then recalibrate once you have a real net-profit figure and a prior-year return to anchor the safe harbor.

How CentSense Makes the Set-Aside Accurate

Your set-aside is only as good as your knowledge of your net profit — and that depends on capturing every deduction. CentSense scans each business receipt, tags it to the right Schedule C line, and logs mileage at the 2026 rate, so you always know your real profit, not just your revenue. That turns "save 30% and hope" into "save 28% of a number I can actually see," and the categorized export makes your quarterly estimates and year-end filing fast.

Frequently Asked Questions

What percentage should freelancers set aside for taxes?

A common rule of thumb is 25–30% of net profit. That covers the 15.3% self-employment tax plus a typical federal bracket. High earners or high-tax states should lean toward 30–40%; modest earners in no-tax states may need only the low-to-mid 20s.

Do freelancers pay more taxes than employees?

On the same income, yes — because of self-employment tax. Employees split the 15.3% Social Security/Medicare tax with their employer; freelancers pay all 15.3% themselves on 92.35% of net profit. You can deduct half of it above the line, but you still owe more than a W-2 employee on identical earnings.

Should I save based on gross income or net profit?

Net profit. Taxes are on profit, not revenue, so saving a percentage of gross over-saves. Track deductible expenses as you go to know your real net profit, then set aside your percentage of that.

How often do freelancers pay taxes?

Quarterly — roughly mid-April, mid-June, mid-September, and mid-January — via estimated tax payments, since no employer withholds for you. The safe-harbor rule (90% of this year's tax or 100%/110% of last year's) avoids underpayment penalties.

What's the easiest way to avoid a surprise tax bill?

Move your tax percentage into a separate savings account every time you're paid, rather than saving leftovers at year-end. Combine that with quarterly payments and accurate expense tracking, and April becomes a formality.
