How Much to Set Aside for Taxes on 1099 Income?

Most independent contractors should set aside 25% to 30% of their gross 1099 income for taxes. That range covers federal self-employment tax, federal income tax, and state income tax for a typical contractor. Where you land inside it, or outside it, depends on how much you earn, your filing status, the deductions you claim, and whether your state taxes income at all.

No employer is withholding anything from your payments, so the money has to come from you. The safest habit is to move your set-aside percentage into a separate account every time a client pays you, and then send it to the IRS in quarterly installments.

What the 25% to 30% Actually Pays For

Three taxes stack on top of your 1099 income. Understanding each one is how you decide whether your personal number is closer to 22% or closer to 32%.

Self-Employment Tax

Every independent contractor owes self-employment tax, which funds Social Security and Medicare. The combined rate is 15.3%, made up of 12.4% for Social Security and 2.9% for Medicare.¹ Traditional employees split these contributions with their employer. As a 1099 worker, you pay both halves.

The rate does not apply to your full net profit. You first multiply net self-employment earnings by 92.35%, then apply 15.3% to that reduced figure.² On $100,000 of net profit, self-employment tax applies to $92,350, so the effective rate is closer to 14.1%.

The 12.4% Social Security portion only applies to earnings up to the annual wage base, which is $184,500 for 2026.³ Net earnings above that ceiling are subject only to the 2.9% Medicare portion. Self-employment tax kicks in once your net profit reaches $400 for the year.

You can deduct half of your self-employment tax as an adjustment to gross income on Form 1040. That does not lower the self-employment tax itself, but it does reduce the income subject to federal income tax.²

High earners owe an extra 0.9% Medicare tax on self-employment income above $200,000 for single filers, $250,000 for married filing jointly, and $125,000 for married filing separately.⁴ These thresholds do not adjust for inflation.

Federal Income Tax

Self-employment tax and federal income tax are separate. After calculating self-employment tax, you still owe income tax on your taxable income at graduated rates that range from 10% to 37% for 2026.⁵ Higher rates apply only to income within each bracket, not to your entire earnings.

For a single filer in 2026, the 10% bracket covers taxable income up to $12,400, 12% runs to $50,400, 22% runs to $105,700, and 24% runs to $201,775. The top 37% rate begins at $640,600 for single filers and $768,701 for married couples filing jointly.⁵

Taxable income is not the same as gross 1099 income. You first subtract the standard deduction, which for 2026 is $16,100 for single filers, $32,200 for married filing jointly, and $24,150 for heads of household.⁵

State Income Tax

Most states also tax 1099 income, adding roughly 2.5% to over 13% on top of federal obligations. A handful of states impose no personal income tax at all. Some use a flat rate; others follow a graduated system. Many require their own quarterly estimated payments on a schedule close to the federal one. If you live in a no-tax state, your total set-aside will run well below 25%. In a high-tax state, plan closer to 30% or above. Your state revenue department publishes the current rates.

Working Out Your Own Percentage

The IRS provides Form 1040-ES and its Estimated Tax Worksheet to walk through the full calculation.⁶ A simplified version:

Add up all the 1099 payments and other self-employment income you expect for the year.
Subtract business expenses to arrive at net profit.
Multiply net profit by 92.35%, then apply the 15.3% self-employment tax rate.
Subtract half of that self-employment tax, the standard or itemized deduction, and the qualified business income deduction if you qualify. What’s left is taxable income.
Apply the 2026 federal brackets to your taxable income.
Add your state’s rate.
Divide the total by expected gross income. That’s your personal set-aside percentage.

Two quick benchmarks: a single filer with $75,000 in net self-employment profit and no other income would owe roughly $10,600 in self-employment tax plus about $5,200 in federal income tax after the standard deduction, QBI deduction, and the SE tax adjustment. That totals around $15,800, or about 21% of gross profit before state taxes. At $150,000 in net profit, the combined federal burden climbs closer to 28%. Adding state income tax in the 3% to 5% range is what pushes most contractors into the 25% to 30% zone.

Deductions That Lower What You Actually Owe

Only your net profit is subject to self-employment tax and income tax. Federal law lets you deduct expenses that are ordinary and necessary to run your business.⁷ Supplies, software subscriptions, professional services, business travel, and advertising are common ones. Three deductions matter enough to call out separately, because they can shift your set-aside percentage by several points.

If you use part of your home regularly and exclusively for business, the simplified home office method gives you $5 per square foot of dedicated space, up to 300 square feet, for a maximum of $1,500.⁸ The regular method lets you deduct a proportional share of actual expenses (mortgage interest, utilities, insurance) and often produces a larger deduction for bigger spaces.

You can also deduct 100% of health insurance premiums paid for yourself, your spouse, and your dependents if the plan is established under your business. This adjustment lowers your income tax but not your self-employment tax, and it’s not available for any month you were eligible for a subsidized employer plan, including one through a spouse’s job.⁹

Retirement contributions cut taxable income the fastest. A SEP-IRA allows contributions up to 25% of net self-employment earnings, capped at $69,000 for 2026.¹⁰ A Solo 401(k) lets you contribute as both employer and employee, with a combined limit of $72,000 for 2026, plus catch-up amounts if you’re 50 or older.

Beyond those, many 1099 workers qualify for the qualified business income deduction under Section 199A, worth up to 20% of qualified business income. It applies to pass-through businesses, which includes the sole proprietorship structure most contractors default into. For 2026 the deduction is straightforward below roughly $201,750 for single filers and $403,500 for married filing jointly. Above those thresholds, restrictions phase in, and contractors in specified service fields like law, accounting, consulting, financial services, and health care lose the deduction entirely once income exceeds the upper limit of the phase-out range.¹¹ The QBI deduction reduces income tax only, not self-employment tax.

Paying What You Set Aside

The IRS expects estimated tax payments four times a year rather than one lump payment in April. The 2026 due dates:

First quarter (January through March): April 15, 2026
Second quarter (April through May): June 15, 2026
Third quarter (June through August): September 15, 2026
Fourth quarter (September through December): January 15, 2027

You can skip the January 15 payment if you file your 2026 return and pay the full balance by February 1, 2027.⁶

IRS Direct Pay transfers funds from your bank account without registration.¹² The Electronic Federal Tax Payment System (EFTPS) lets you schedule payments in advance and track history, but you need to enroll and wait five to seven business days for a PIN by mail.¹³ Check or money order works too, using the vouchers included with Form 1040-ES.

If your income swings hard through the year, the annualized income installment method calculates each quarter’s payment based on income actually earned in that period, instead of dividing an annual estimate into four equal chunks.¹⁴

What Happens If You Set Aside Too Little

The IRS charges a penalty when you don’t pay enough tax during the year. It’s calculated as interest on the underpayment for the time it stayed unpaid, at the federal short-term rate plus three percentage points. That was 7% for the first quarter of 2026 and 6% for the second.¹⁵

Three safe harbors let you avoid the underpayment penalty entirely:¹⁶

You owe less than $1,000 after subtracting withholding and credits.
You paid at least 90% of the tax shown on your current-year return.
You paid at least 100% of the tax shown on your prior-year return. If your adjusted gross income was above $150,000 ($75,000 for married filing separately), the threshold rises to 110%.¹⁷

The prior-year safe harbor is especially useful in your first strong year as a contractor. If last year’s tax bill was small, paying 100% (or 110%) of that smaller amount blocks the penalty even if your current income is much higher. That gives you room to fine-tune your set-aside percentage without getting punished for guessing wrong.
