How much should you set aside for taxes when you're self-employed?
If you're a freelancer, 1099 contractor, or run your own small business, no one is withholding taxes from your pay. That job is now yours. The good news: you don't need a spreadsheet or a finance degree to get it right. You need a simple habit — set aside a slice of every payment — and a rough idea of how big that slice should be.
The short answer most people are looking for: set aside about 25–30% of your net self-employment income for taxes. That's a sound starting point for many people at low-to-moderate income. But "it depends" is the honest full answer, so this guide explains where that range comes from, when you'd want to go higher or lower, and how to land on a number that fits your situation.
Why 25–30% is the common rule of thumb
When you're self-employed, your tax bill is really two taxes stacked together:
- Self-employment (SE) tax — this funds Social Security and Medicare. As an employee you'd split these with an employer; on your own, you pay both halves. The SE tax rate is 15.3% on net earnings (12.4% Social Security up to an annual wage base, plus 2.9% Medicare), per the IRS Self-Employment Tax overview.
- Federal income tax — the same progressive brackets everyone pays, applied to your taxable income. This might be roughly 10–22% of a typical freelancer's income after deductions, but it climbs at higher incomes.
Stack a ~15% SE tax on top of a ~10–15% effective income tax rate and you land in the mid-to-high 20s — which is exactly why 25–30% is such a durable rule of thumb. It's not a law; it's arithmetic that happens to work out for a lot of people.
Set aside a percentage of profit, not revenue
This is the mistake that trips people up most. You are taxed on your net profit — what's left after deductible business expenses — not on everything that lands in your account. If you invoice $8,000 in a month but spent $2,000 on software, mileage, and supplies, your profit is $6,000, and that's the number to apply your set-aside percentage to.
A useful side effect of tracking expenses is that legitimate deductions lower both your income tax and your SE tax. Our guide to 1099 tax deductions walks through the write-offs freelancers miss most.
When to set aside more than 30%
Nudge your percentage up if any of these describe you:
- You live in a state with income tax. Most guides quote federal-only numbers. State income tax can add several percentage points on top. Check your state's rules.
- You have a high-earning household. If a spouse's W-2 income or your own high profit pushes you into higher federal brackets, your effective income-tax rate rises and 25% won't cut it.
- Your income jumped this year. A big year can mean a bigger bracket than last year's habits assumed.
- You have few deductions. Less to write off means more taxable profit.
When 20–25% may be enough
You might safely set aside a bit less if you have significant business deductions, a lower total household income, or you qualify for credits that reduce your bill. Even then, err on the side of over-saving. Setting aside a little too much simply turns into savings or a refund; setting aside too little turns into a stressful bill — and possibly a penalty — you didn't plan for.
Worked examples (illustrations only)
The tables below are simplified illustrations to show how the pieces fit together — not a promise of your result. They assume a single filer with no state income tax and standard simplifications, and they ignore credits, the deduction for one-half of SE tax, the qualified business income deduction, and other factors that would change real numbers. Your actual figures will differ. Verify with the IRS or a tax professional.
| Net profit (illustration) | Rough combined rate to set aside | Why |
|---|---|---|
| ~$30,000 | ~20–25% | SE tax applies, but income tax is low at this level after the standard deduction. |
| ~$60,000 | ~25–30% | The classic middle case — SE tax plus a moderate income-tax rate. |
| ~$100,000 | ~28–33% | Higher income-tax brackets start to lift the combined rate. |
| ~$150,000+ | ~30–35%+ | More income taxed at higher brackets; add state tax where applicable. |
Read these as directions on a map, not a GPS destination. The pattern to notice: the percentage rises as income rises, because income tax is progressive while SE tax is roughly flat. That's why a single fixed percentage can't be right for everyone — and why running your own numbers matters.
A simple system that actually works
The mechanics matter more than precision. A set-aside plan you follow beats a perfect number you ignore. Here's a calm, low-effort routine used by a lot of self-employed people:
- Open a separate savings account just for taxes — ideally high-yield, so the money earns a little while it waits. See our business banking guide.
- Every time you get paid, move your percentage (say 30%) into that account immediately. Out of sight, out of spending.
- Pay your quarterly estimates from it. The set-aside account funds your four estimated-tax payments, so deadlines don't sting.
- Reconcile once a year. Whatever's left after your tax bill is yours — savings, a buffer, or a head start on next year.
Because this money leaves for the IRS four times a year, our quarterly estimated taxes guide and the quarterly tax calculator are the natural next step once you know your percentage.
Frequently asked questions
How much should a 1099 worker set aside for taxes?
A common rule of thumb is 25–30% of your net self-employment income, which covers both SE tax and federal income tax for many people at moderate income. Your real number depends on your profit, other household income, deductions, and your state — so treat 25–30% as a starting point and refine it with a calculator.
Is 30% enough to set aside for self-employment taxes?
For many self-employed people at low-to-moderate income, 30% is a reasonably safe cushion. Higher earners, people in higher-tax states, or those with significant other income may need more. Setting aside slightly too much is usually better than too little — the surplus becomes savings or a refund.
Do I set aside a percentage of gross income or net profit?
Base it on net profit — business income after deductible expenses — not gross revenue. You're taxed on profit, so a percentage of gross would usually over-save. Track expenses so you know your true profit.
Where should I keep the money I set aside?
Many self-employed people move their set-aside into a separate high-yield savings account each time they're paid, keeping it out of sight until the quarterly deadline. Separating it from spending money reduces the temptation to dip in.
What if I set aside too little?
You may owe more than expected at filing and could face an underpayment penalty. If you catch it mid-year, raise your set-aside percentage and consider a larger next quarterly payment to catch up. A tax pro can help you avoid penalties.
