How Much to Save for Taxes as a 1099 Contractor
A common rule of thumb is to set aside 25–30% of your net self-employment income for taxes, because as a 1099 contractor you owe both income tax and the full self-employment tax (about 15.3% for Social Security and Medicare) that an employer would normally split with you. The exact percentage depends on your income, state, and deductions, so a lower earner might land near 20% and a higher one above 30% — but automatically moving 25–30% of each payment into a separate account keeps you from being caught short at tax time.
Why a 1099 owes more than a W-2
As a contractor, you’re both the employee and the employer for tax purposes. That means you pay the full self-employment tax — roughly 15.3% for Social Security and Medicare — that a boss would normally split with you, plus your regular income tax on top. Under-saving is the classic first-year 1099 mistake.
The 25–30% rule
Set aside 25–30% of your net income (what’s left after business expenses) from every payment. Lower earners may land closer to 20%; higher earners above 30%. When in doubt, save toward the top of the range — over-saving just means a refund to yourself.
Do it automatically
Move the set-aside the moment you get paid, into a separate account you don’t touch. A percentage swept off each payment turns tax season from a scramble into a transfer, because the money’s already there.
Remember quarterly estimates
The IRS generally wants quarterly estimated payments, not one April lump. If you’ve been setting aside 25–30% all along, each quarterly payment comes straight from that account without denting your operating cash.
Deductions lower the real number
Mileage, tools, supplies, phone, and home office all reduce taxable income, so your actual bill may be less than you saved. Keeping clean records of income and expenses all year is what lets you — or your accountant — claim them and keep the difference.

Frequently asked questions
Why is it more than a regular employee pays?
As a 1099 contractor you pay self-employment tax — the full ~15.3% for Social Security and Medicare — on top of income tax, because there's no employer covering half of it like there is on a W-2. That's why 25–30% is a safer set-aside than the smaller amount many first-year contractors assume.
Do I pay taxes once a year or quarterly?
If you'll owe a meaningful amount, the IRS expects quarterly estimated payments, not one lump sum in April. Missing them can mean penalties. Setting aside money from each payment makes those quarterly payments painless because the cash is already waiting.
Does saving 30% mean I actually owe 30%?
Not necessarily — it's a buffer. Deductions (mileage, tools, supplies, home office, phone) lower your taxable income, so you may owe less and keep the difference. Saving 25–30% and adjusting with an accountant beats under-saving and scrambling.
