Set aside roughly 25-30% of your net self-employment income for taxes. That covers self-employment tax (about 15.3% of net) plus federal and, in most states, state income tax. If you earn a lot, live in a high-tax state, or have little in deductions, aim closer to 30-35%; if your income is modest and deductions are strong, low 20s can be enough.
The percentage isn’t a mystery, but it does move around based on how much you make, where you live, and what you can write off. The 25-30% rule is a safe default that keeps most freelancers out of trouble. Below is where that number comes from, a worked example with actual dollars, and how to stop guessing.
Why self-employed taxes hit harder than a W-2
When you worked for someone else, your employer quietly paid half of your Social Security and Medicare taxes. As a 1099 contractor, you’re both the employer and the employee, so you pay the whole thing. That’s self-employment tax: 15.3% of your net profit (12.4% Social Security up to the annual wage cap, plus 2.9% Medicare with no cap).
Self-employment tax is calculated on 92.35% of your net earnings, and you get to deduct half of it when figuring income tax. Small mercies. But the headline number stands: before a dollar of income tax, you already owe about 15 cents on the dollar. Stack federal income tax (10-24% for most freelancers) and state income tax (0% in states like Texas and Florida, up to ~9-13% in California) on top, and the 25-30% set-aside makes sense fast.
A worked example: $50,000 in net profit
Say you’re a single freelance designer who cleared $50,000 in net profit (that’s revenue minus business expenses) in a no-income-tax state.
| Line | Amount |
|---|---|
| Net profit | $50,000 |
| Self-employment tax (15.3% of $46,175) | ~$7,065 |
| Taxable income after half-SE and standard deductions | ~$25,000-$31,000 |
| Federal income tax (roughly 10-12% brackets) | ~$2,800 |
| Total federal tax | ~$9,900 |
That’s about 20% of net profit in a state with no income tax. Add a typical 4-6% state rate and you’re right in the 24-26% zone. Push that income to $90,000 or add California, and the effective rate climbs toward 30% or more because more of your money falls into higher brackets. This is exactly why a flat 25-30% works as a default and why the top of that range is the safer bet the more you earn.
Watch out: Set aside a percentage of net profit, not gross revenue. If you bill $80,000 but spend $30,000 on software, contractors, and mileage, your tax is calculated on the $50,000 that’s left. Setting aside 30% of the full $80,000 would over-save by thousands and starve your cash flow.
Quarterly estimated taxes: the part people forget
The IRS doesn’t want to wait until April. If you expect to owe $1,000 or more for the year, you’re generally supposed to pay estimated taxes four times a year. Miss them and you can get hit with an underpayment penalty even if you pay in full by the deadline.
The 2026 due dates follow the usual pattern:
- Q1 (Jan-Mar income): mid-April
- Q2 (Apr-May income): mid-June
- Q3 (Jun-Aug income): mid-September
- Q4 (Sep-Dec income): mid-January of the next year
The cleanest system: open a separate savings account, move your 25-30% into it every time a client pays you, and send a check from that account each quarter. When the money never touches your checking account, you’re never tempted to spend it, and quarterly payments stop feeling like a surprise. Some free tax and income tools for the self-employed can help you estimate each quarter’s payment so you’re not flying blind.
How deductions lower the number you owe
Every legitimate business expense reduces the net profit your taxes are based on, which lowers both self-employment tax and income tax. Common ones for 1099 workers:
- Home office (a portion of rent, utilities, and internet)
- Business mileage or vehicle costs
- Software, subscriptions, and tools of your trade
- Health insurance premiums (self-employed health insurance deduction)
- Half of your self-employment tax
- The qualified business income (QBI) deduction, which can knock up to 20% off qualifying business income
Here’s the practical takeaway: strong deductions can drop your effective rate several points, which is why disciplined tracking often matters more than the exact percentage you choose. If you earn tips or a mix of income types, run the numbers with a Tip Income Tax Calculator and other free self-employed tools before assuming a flat rate covers you.
Adjusting the percentage to your situation
Use this as a starting grid, then refine as you see your real numbers:
| Your situation | Set aside |
|---|---|
| Lower income, no state tax, solid deductions | 20-25% |
| Most freelancers, average state tax | 25-30% |
| Higher income or high-tax state (CA, NY) | 30-35% |
One honest caveat: these are ballpark ranges, not a filing. A spouse’s W-2 income, kids, retirement contributions, and state quirks can all shift your real number. Once a year, it’s worth confirming your rate with a tax pro, especially your first year self-employed or after a big income jump. The set-aside habit is what keeps you solvent between those check-ins.
Frequently asked questions
Is 30% enough to set aside for 1099 taxes?
For most freelancers, yes. 30% comfortably covers self-employment tax plus federal and typical state income tax at moderate income levels. If you’re a high earner or live in a state like California or New York, budget 30-35% to be safe.
Do I set aside on gross or net income?
Net. Your taxes are based on profit after business expenses, not total revenue. Save your percentage of what’s left once you subtract deductible costs, or you’ll dramatically over-save.
What happens if I don’t pay quarterly estimated taxes?
You can owe an underpayment penalty plus interest, even if you pay the full balance in April. If you expect to owe $1,000 or more for the year, plan to make the four quarterly payments.
Does the 25-30% include state taxes?
In states with average income tax rates, yes. If you live somewhere with no state income tax, you can lean toward the lower end. In high-tax states, add a few points on top.
How do deductions change how much I should save?
More deductions mean lower net profit, which lowers both self-employment and income tax. Strong, well-tracked deductions can pull your effective rate down several points, but only if you’re actually recording them throughout the year.
Should I open a separate account for taxes?
It’s the single easiest habit that works. Move 25-30% of every client payment into a dedicated savings account, and pay each quarter from there. The money you never see is the money you never accidentally spend.
