1099 income is taxed as self-employment income, not as wages

When you receive a 1099 form instead of a W-2, you owe taxes on that income in two ways: income tax and self-employment tax. The income tax rate depends on your total income and filing status — it follows the same federal tax brackets as everyone else. But self-employment tax is the additional piece: you pay both the employer and employee portions of Social Security and Medicare, which adds roughly 15.3% on top of your income tax.

The IRS does not treat 1099 income differently from wages for income tax purposes. What changes is that you are responsible for calculating and paying all of it yourself, usually in quarterly installments, rather than having an employer withhold it from each paycheck.

Key Takeaways

  • Self-employment tax in 2023 is 15.3% (12.4% for Social Security on income up to $160,200, plus 2.9% for Medicare on all income).
  • You also owe regular income tax on your 1099 income at the federal rate that matches your total income and filing status, ranging from 10% to 37% in 2023.
  • You can deduct half of your self-employment tax from your income before calculating income tax, which reduces your overall tax burden.
  • If you expect to owe $1,000 or more in taxes on 1099 income, you must make quarterly estimated tax payments to avoid penalties.

Federal income tax brackets for 1099 income in 2023

Your 1099 income is added to any other income you have — wages, interest, capital gains — and taxed according to the 2023 federal tax brackets. The rate you pay depends on your total income and whether you file as single, married filing jointly, head of household, or another status.

For 2023, the federal income tax rates are 10%, 12%, 22%, 24%, 32%, 35%, and 37%. A single filer with $50,000 in 1099 income, for example, would owe income tax at rates ranging from 10% to 22% on that income, not a flat rate. The exact amount depends on how much of that income falls into each bracket.

State income tax also applies to 1099 income in most states. The rate varies by state — some states have no income tax, while others tax 1099 income at rates between 3% and 13%. You will owe both federal and state income tax on the same 1099 income.

Self-employment tax: the additional 15.3%

Self-employment tax covers Social Security and Medicare for people who work for themselves. In 2023, the rate is 15.3%: 12.4% for Social Security and 2.9% for Medicare. You calculate it on your net self-employment income — your 1099 income minus business expenses and a deduction for half of your self-employment tax itself.

The Social Security portion (12.4%) only applies to income up to $160,200 in 2023. Income above that threshold is not subject to the Social Security portion, though it is still subject to the 2.9% Medicare tax. If you have 1099 income of $200,000, you would pay the full 15.3% on the first $160,200 and only 2.9% on the remaining $39,800.

Self-employment tax is separate from income tax. You owe both. A person with $40,000 in 1099 income owes roughly $5,700 in self-employment tax (15.3% of $40,000 minus the self-employment tax deduction), plus whatever income tax applies based on their total income and tax bracket.

How to calculate what you owe on 1099 income

Start with your net 1099 income: the amount on the 1099 form minus any business expenses you can deduct (office supplies, equipment, mileage, home office, professional services). The IRS allows you to deduct legitimate business costs, which lowers your taxable income.

Next, calculate self-employment tax on 92.35% of that net income (the other 7.65% is already accounted for in the formula). Multiply by 15.3%. That is your self-employment tax. You can then deduct half of that self-employment tax from your income before calculating income tax.

Finally, add your 1099 income (minus business expenses and minus half of self-employment tax) to any other income you have, and apply the 2023 federal tax brackets for your filing status. That gives you your income tax. Add the income tax and self-employment tax together to find your total federal tax on 1099 income.

Form 1040 Schedule C is where you report 1099 income and business expenses. Schedule SE is where you calculate self-employment tax. Both are filed with your annual tax return.

Quarterly estimated tax payments

If you expect to owe $1,000 or more in federal income tax and self-employment tax combined for 2023, you must make quarterly estimated tax payments. These are due on April 18, June 15, September 15, 2023, and January 16, 2024. Paying late or underpaying can result in penalties and interest.

To calculate your quarterly payment, estimate your total 1099 income for the year, subtract business expenses, calculate the income tax and self-employment tax you expect to owe, and divide by four. If your income is uneven across the year, you can pay more in quarters when you earn more and less in quarters when you earn less.

You make estimated payments using Form 1040-ES, which you can file online through the IRS website or by mail. Many people use tax software or a tax professional to calculate the correct amount, since underpaying triggers penalties even if you ultimately owe less than expected.

Deductions and credits that reduce 1099 taxes

You can deduct business expenses directly from your 1099 income before calculating taxes. Common deductions include office rent or a home office deduction, equipment and supplies, vehicle mileage (58.5 cents per mile in 2023), professional services, insurance, and education related to your work. Keeping receipts and records is essential — the IRS can ask for proof of any deduction you claim.

The standard deduction also applies to 1099 income. In 2023, the standard deduction is $13,850 for single filers and $27,700 for married filing jointly. This reduces your taxable income before income tax is calculated, though it does not reduce the income subject to self-employment tax.

Tax credits like the Earned Income Tax Credit (EITC) may also reduce what you owe if your 1099 income is below certain thresholds. Unlike deductions, credits reduce your tax dollar-for-dollar. A tax professional can help you identify which credits you may be may have access to to claim.

Frequently Asked Questions

Do I owe taxes on 1099 income if I made less than $12,000?

You owe self-employment tax on 1099 income of $400 or more, regardless of how much you earned overall. Income tax depends on your total income and filing status. If your only income is $12,000 in 1099 income and you are single, you would owe self-employment tax but likely little or no income tax because $12,000 is below the standard deduction.

What if I received a 1099 but the amount is wrong?

Contact the person or business who issued the 1099 and ask them to file a corrected form (1099-X) with the IRS and send you a copy. You should receive the corrected form before you file your tax return. If you file before receiving it, you may need to file an amended return once you get the correct amount.

Can I deduct my home office if I have 1099 income?

Yes. You can use the simplified method (claiming $5 per square foot, up to 300 square feet) or calculate actual expenses like rent, utilities, and insurance. The deduction reduces your net self-employment income and therefore reduces both self-employment tax and income tax.

What happens if I do not pay quarterly estimated taxes?

The IRS charges penalties and interest on underpayment. The penalty is typically 3% to 5% of the amount you should have paid. If you owe a large amount at tax time, the penalty can be substantial. Paying quarterly, even if your estimate is slightly off, usually avoids or minimizes the penalty.

Is 1099 income taxed differently if I am retired or on Social Security?

1099 income is taxed the same way regardless of your other income sources. However, 1099 income can affect how much of your Social Security is taxed. If your combined income (including half your Social Security benefits plus your 1099 income) exceeds certain thresholds, up to 85% of your Social Security may become taxable.
