How Much Should You Set Aside From Your 1099 Income for Taxes

The basic rule: set aside 25 to 30 percent of what you earn

If you are a 1099 contractor, you should set aside roughly 25 to 30 percent of your gross income for federal taxes, self-employment tax, and state income tax combined. This is not a legal requirement — the IRS does not mandate a specific percentage — but it is a practical target based on how 1099 taxes actually work.

The reason the range is wide is that your exact obligation depends on three things: your total income for the year, your state's income tax rate (which ranges from zero to over 13 percent depending on where you live), and whether you have business expenses you can deduct. A freelancer in Florida with $40,000 in income and $8,000 in deductible expenses will owe far less than a freelancer in California with $40,000 in income and no deductions.

The 25 to 30 percent figure assumes you have some deductible business expenses and live in a state with moderate income tax. If you live in a state with no income tax, you can aim lower. If you have no business expenses, you should aim higher.

Key Takeaways

• Set aside 25 to 30 percent of your gross 1099 income for all taxes combined, but adjust this based on your state's income tax rate and whether you have business expenses.
• Self-employment tax (Social Security and Medicare) is 15.3 percent of your net profit and is the largest tax bill most 1099 workers face.
• Federal income tax varies by your total income and filing status, so your actual rate could be 10, 12, 22 percent or higher depending on your tax bracket.
• Quarterly estimated tax payments are required if you expect to owe $1,000 or more in federal taxes for the year, and missing them can result in penalties.
• Tracking your income and expenses throughout the year makes it much easier to calculate what you actually owe instead of guessing.

Why self-employment tax is your biggest expense

When you are a W-2 employee, your employer pays half of your Social Security and Medicare taxes. When you are a 1099 contractor, you pay both halves yourself. This is called self-employment tax, and it totals 15.3 percent of your net profit (your income minus deductible business expenses).

For example, if you earn $50,000 as a 1099 contractor and have $5,000 in deductible business expenses, your net profit is $45,000. Self-employment tax on that is roughly $6,900. That alone is 13.8 percent of your gross income. Add federal income tax (which depends on your bracket but is typically 10 to 22 percent of taxable income) and state income tax, and you can easily reach 25 to 30 percent of gross income.

You can deduct half of your self-employment tax when you calculate your federal income tax, which reduces the total slightly. But self-employment tax is still the largest single tax bill most 1099 workers face.

How federal income tax changes with your total earnings

Federal income tax is not a flat percentage — it uses tax brackets, which means different portions of your income are taxed at different rates. In 2024, the federal brackets for a single filer range from 10 percent on the first $11,600 of taxable income to 37 percent on income above $578,100.

Your taxable income is your gross income minus your standard deduction (which is $14,600 for a single filer in 2024) and any deductible business expenses. So if you earn $50,000 as a 1099 contractor with $5,000 in business expenses, your taxable income is roughly $30,400 ($50,000 minus $14,600 standard deduction minus $5,000 in expenses). That puts you in the 12 percent bracket, meaning you owe federal income tax of roughly $3,600.

The brackets change every year, and they are higher for married filers and lower for heads of household. The IRS publishes the current brackets on its website each January. If you are unsure which bracket you fall into, you can use the IRS tax withholding estimator tool to get a rough number.

State income tax varies dramatically by location

Nine states have no income tax at all: Alaska, Florida, Nevada, South Dakota, Tennessee, Texas, Washington, Wyoming, and New Hampshire (which taxes only dividends and interest, not wages). If you live in one of these states, you can subtract 0 percent from your 25 to 30 percent target.

Most other states tax income between 3 and 6 percent. California, Hawaii, and Oregon tax at rates above 10 percent. If you live in a high-tax state and earn a significant income, you may need to set aside 35 to 40 percent instead of 25 to 30 percent.

Some states also have local income taxes on top of state income tax. New York City, for example, adds roughly 3.9 percent on top of New York State's income tax. Check your state's revenue department website to find your exact rate.

How to calculate what you actually owe instead of guessing

The most accurate way to know what to set aside is to calculate your actual tax liability using your real numbers. You will need three pieces of information: your year-to-date gross income, your year-to-date business expenses, and your filing status.

Start by subtracting your business expenses from your gross income to get your net profit. Multiply your net profit by 0.9235 (this accounts for the self-employment tax deduction). Then subtract your standard deduction. The result is your taxable income. Use the current year's federal tax brackets to calculate your federal income tax. Multiply your net profit by your state's income tax rate to get your state income tax. Add federal income tax, state income tax, and self-employment tax (net profit × 0.153) to get your total tax bill.

This calculation is tedious to do by hand, which is why many 1099 contractors use tax software or a spreadsheet. Some accounting software for freelancers (like QuickBooks Self-Employed or FreshBooks) can calculate estimated taxes automatically if you log your income and expenses as you go.

Quarterly estimated tax payments and penalties for missing them

If you expect to owe $1,000 or more in federal taxes for the year, the IRS requires you to make quarterly estimated tax payments on April 15, June 15, September 15, and January 15. Each payment should cover roughly one-quarter of your expected annual tax bill.

If you do not make these payments and you owe more than $1,000 at tax time, you will face an underpayment penalty. The penalty is not huge — it is based on the federal interest rate, which is currently around 8 percent per year — but it adds up if you owe a large amount. For example, if you owe $5,000 in taxes and make no quarterly payments, the penalty could be $200 to $400.

You can make estimated tax payments through the IRS website using the Electronic Federal Tax Payment System (EFTPS), or you can mail a check with Form 1040-ES. Many tax software packages also allow you to pay directly. If your income is uneven throughout the year, you can adjust your quarterly payments to match — you do not have to pay exactly one-quarter each time.

What counts as a deductible business expense

The more business expenses you can deduct, the lower your taxable income and the less you owe in taxes. Common deductible expenses for 1099 contractors include home office space (either a percentage of your rent or mortgage, or a flat $5 per square foot up to 300 square feet), equipment and supplies, software subscriptions, professional development, and vehicle mileage.

You can only deduct expenses that are ordinary and necessary for your business. Personal expenses do not count. For example, you can deduct the cost of a laptop you use for work, but not the cost of a laptop you use for personal browsing. You can deduct internet if you use it partly for work, but you have to calculate the percentage that is work-related.

Keep receipts and records for all expenses you deduct. The IRS does not require you to submit them with your tax return, but if you are audited, you will need to prove that the expenses were real and business-related. Many contractors use accounting software or a straightforward spreadsheet to track expenses throughout the year.

Frequently Asked Questions

Do I have to set aside exactly 25 to 30 percent, or is it just a guideline?

It is a guideline, not a legal requirement. The IRS does not mandate a specific percentage. But if you set aside less and owe more than $1,000 at tax time, you will face an underpayment penalty. Setting aside 25 to 30 percent protects you from that penalty in most cases.

What if I set aside too much and overpay my taxes?

You will receive a refund when you file your tax return. The refund will be mailed to you or deposited into your bank account, depending on how you file. There is no penalty for overpaying — the IRS straightforward returns the excess.

Can I change my quarterly estimated tax payment if my income changes mid-year?

Yes. If your income is higher or lower than you expected, you can adjust your remaining quarterly payments to match your new estimate. You do not have to pay the same amount each quarter — you only have to pay enough by the end of the year to avoid an underpayment penalty.

What if I have a loss instead of a profit?

If your business expenses exceed your income, you have a loss. You do not owe self-employment tax on a loss, and you can use the loss to reduce your other income (if you have a W-2 job, for example). You may not need to make quarterly estimated tax payments if you do not expect to owe anything.

Should I hire an accountant or use tax software?

Tax software is sufficient for most 1099 contractors with straightforward income and expenses. An accountant is worth considering if your situation is complex (multiple income streams, significant business expenses, rental property income) or if you want someone else to handle the calculations and quarterly payments.
