How Much Should You Withhold for 1099 Taxes? The 25-30% Rule

Most independent contractors should set aside 25% to 30% of their net 1099 income for federal taxes. That range is where the answer to how much to withhold for 1099 taxes lands for the majority of self-employed filers, because you’re covering two taxes at once: the 15.3% self-employment tax that funds Social Security and Medicare, and federal income tax at your marginal bracket. Nobody is holding this money back from your payments, so you have to do it yourself and send it to the IRS in quarterly installments.

The exact percentage depends on your bracket, your deductions, and whether you have other income. Someone in the 12% bracket with heavy business expenses might get away with 22%. A single filer clearing $200,000 in profit should be closer to 33%. Start with 30% if you have no other information; adjust from there once you’ve run your own numbers.

The Two Taxes Stacked on Your 1099 Income

Forgetting self-employment tax is the single most common reason new freelancers get blindsided in April. It sits on top of income tax, not inside it.

Self-Employment Tax: A Flat 15.3%

W-2 employees split FICA with their employer, each side paying 7.65%. You pay both halves, for a combined 15.3%: 12.4% for Social Security and 2.9% for Medicare.¹

The tax runs on net earnings, not gross revenue. Subtract business expenses to get net profit, then multiply by 92.35% to get “net earnings from self-employment.” The 92.35% factor exists because employees don’t pay FICA on the employer’s share of the tax, and this adjustment gives you similar treatment.¹

The 12.4% Social Security portion stops at a wage base limit, set at $184,500 for 2026.² If you also earn W-2 wages, those wages count toward the cap first. The 2.9% Medicare portion has no cap. An extra 0.9% Medicare surtax applies to earnings above $200,000 for single filers or $250,000 for joint filers.³

Federal Income Tax on Top

Your net 1099 profit also flows into your adjusted gross income and gets taxed at ordinary rates. One built-in break: you deduct half of your self-employment tax when figuring AGI.⁴ That reduces income tax, not self-employment tax.

The 2026 brackets for single filers are 10% up to $12,400, 12% to $50,400, 22% to $105,700, 24% to $256,225, 32% to $640,600, and 37% above that. Married-filing-jointly thresholds roughly double. The 2026 standard deduction is $16,100 for singles and $32,200 for joint filers.⁵

Most states tax self-employment income too, and most require their own quarterly estimates. Rates and thresholds vary; check your state tax authority and add that percentage on top of your federal set-aside.

What 25% to 30% Looks Like on Real Numbers

A single freelancer with $80,000 in net profit for 2026 and no other income runs the math like this:

Net earnings from self-employment: $80,000 × 92.35% = $73,880
Self-employment tax: $73,880 × 15.3% = about $11,304
Half of SE tax deducted from gross: $5,652
Taxable income after standard deduction: roughly $58,248
Federal income tax through the brackets: about $8,017
Combined federal tax: about $19,321, or just over 24% of net profit

Setting aside 25% each time you get paid would leave you slightly ahead. This example ignores extra business deductions, the QBI deduction, and state tax, each of which will move the number. It’s meant to show how the two taxes stack to land in that 25%–30% zone.

Deductions That Lower the Percentage You Need to Withhold

Every dollar of legitimate deduction cuts both income tax and, when taken on Schedule C, self-employment tax. Tracking them well is the most reliable way to bring your set-aside closer to 25% than 30%.

Schedule C Business Expenses

Ordinary and necessary expenses come off before self-employment tax hits: supplies, software, subscriptions, advertising, professional services, business insurance, rent. The 2026 standard mileage rate is 72.5 cents per business mile.⁶ A dedicated home office qualifies for the simplified $5-per-square-foot deduction up to 300 square feet ($1,500 cap), or you can calculate actual expenses for potentially more.⁷

Self-Employed Health Insurance

If you pay your own premiums and aren’t eligible for coverage through a spouse’s employer plan, 100% of premiums for you, your spouse, and your dependents is deductible. It comes off on Schedule 1 as an adjustment to income, so it reduces income tax but not self-employment tax. You get it whether or not you itemize.

Retirement Contributions

A SEP IRA allows up to 25% of net self-employment earnings, capped at $72,000 for 2026.⁸ A solo 401(k) adds an employee elective deferral of up to $24,500 ($32,500 if you’re 50 to 59 or over 64, and $35,750 if you’re 60 to 63), with the same $72,000 combined ceiling under 50. These contributions reduce taxable income dollar for dollar.

Qualified Business Income (QBI) Deduction

Section 199A lets eligible self-employed filers deduct up to 20% of qualified business income from taxable income, and the One Big Beautiful Bill made this deduction permanent starting in 2026. The full 20% is available if your 2026 taxable income before the QBI deduction is $201,750 or less for single filers, or $403,500 or less for joint filers. Above those thresholds the deduction phases out, and specified service businesses (law, accounting, consulting, health care, financial services) face tighter limits.⁹ Below the threshold the math is simple: 20% off your QBI, reducing income tax only.

Turning the Percentage Into Quarterly Payments

The IRS requires estimated payments if you expect to owe $1,000 or more after any withholding and refundable credits. Under that threshold, you can settle up at filing time.¹⁰ Above it, you have two ways to size each payment.

Prior-Year Safe Harbor

Take the total tax on last year’s return, multiply by 100% (or 110% if your 2025 AGI was over $150,000, or $75,000 married filing separately), and divide by four.¹¹ Meeting that number guarantees no underpayment penalty regardless of what you actually earn this year. You’ll still owe any remaining balance in April, but the IRS won’t charge you for it.

The safe harbor works best when income is stable or rising modestly. If your income is climbing fast, you can meet the safe harbor and still face a large April bill. That’s cash-flow surprise, not penalty, but it’s worth planning for.

Current-Year Estimate

If last year’s tax doesn’t exist (no liability) or doesn’t reflect this year, project your 2026 income and deductions, calculate combined SE tax and income tax, and pay at least 90% of that across four installments.¹⁰ The worksheet in Form 1040-ES walks through the calculation. If your income arrives unevenly, the annualized income installment method (Schedule AI of Form 2210) lets each quarter’s required payment reflect what you actually earned in that period.

2026 Deadlines and How to Pay

Four federal deadlines cover 2026 income:¹²

April 15, 2026, for income earned January 1 through March 31
June 15, 2026, for April 1 through May 31
September 15, 2026, for June 1 through August 31
January 15, 2027, for September 1 through December 31

The second period is only two months, which catches people every year. Deadlines that fall on a weekend or holiday shift to the next business day. You can skip the January 15 payment if you file your full return and pay the balance by February 1.¹⁰

IRS Direct Pay is the simplest route. It’s free, no registration, and you can schedule from a bank account up to a year ahead.¹³ Your IRS Online Account handles the same payments and keeps a history in one place. EFTPS is still available if you enrolled before October 17, 2025, but new individual enrollments are no longer accepted; the IRS now points new users to Direct Pay or IRS Online Account.¹⁴

Card payments go through IRS-authorized processors and carry fees of 1.75% to 2.95%.¹⁵ On a $5,000 payment, that’s $87 to $147. Those fees are deductible as a business expense, but a free bank transfer is usually the better call. Check or money order with a 1040-ES voucher still works; the slower processing just makes timely delivery harder to verify. IRS2Go offers Direct Pay and card options from your phone.¹⁶ State payments go through your state’s tax authority separately.

What Happens If You Underpay

If your withholding plus estimated payments falls short, the IRS charges an underpayment penalty that works like interest on the shortfall, calculated at the federal short-term rate plus three points and compounded daily. The rate was 7% for the first quarter of 2026 and 6% for the second quarter.¹⁷ It runs separately for each quarter’s shortfall from that quarter’s due date until you pay or file.

No penalty applies if any of these hold:¹¹

Your total tax owed after withholding and credits is under $1,000
You paid at least 90% of your current-year tax
You met the prior-year safe harbor (100% or 110% of last year’s tax)

The IRS usually calculates this penalty and bills you, so most filers don’t need Form 2210. You’d file it to request a waiver or to show that annualized installments were properly timed.¹⁸ The IRS can waive the penalty for casualty, disaster, or other unusual circumstances where charging it would be unfair.¹¹ Worth knowing: the first-time penalty abatement program the IRS offers for late filing and late payment does not apply here, and this penalty generally can’t be waived for reasonable cause. The safe harbor rules are your only reliable protection.

Two Situations That Change the Answer

Backup Withholding

There is one case where tax actually is withheld from a 1099 payment before it reaches you. When a client asks you to complete Form W-9, they’re certifying your taxpayer identification number. If you fail to provide a correct TIN, or the IRS notifies the payer that yours is wrong, the payer must withhold a flat 24% from your payments.¹⁰ That 24% is a blunt figure that may be more or less than your actual rate, and undoing it means resolving the TIN issue with the IRS. Get your W-9 right the first time.

Mixed W-2 and 1099 Income

W-2 withholding counts toward your total tax payments and, unlike estimated payments, is treated as paid evenly throughout the year no matter when it was actually withheld. If you have a day job with a side 1099 business, increasing your W-4 withholding at the day job can replace some or all of your quarterly payments and eliminate the timing risk on shortfalls.

Making the Set-Aside Stick

The math is only half the job. Move your withholding percentage into a separate savings account every time a client pays you, on the same day if possible. Automation removes the temptation to spend it. If your income swings month to month, the prior-year safe harbor is usually easier than recalculating projections every quarter: you know the number on January 1, divide by four, and pay the same amount each time. Save the current-year approach for years when your income has genuinely shifted by a large margin.
