How Much Tax You Pay on 1099 Income

Self-employment tax on a 1099 is 15.3 percent of your net earnings, split between Social Security and Medicare

When you receive a 1099, you owe self-employment tax in addition to regular income tax. Self-employment tax covers Social Security and Medicare — the programs that W-2 employees and their employers split the cost of. Because you are both employee and employer on a 1099, you pay both sides yourself.

The self-employment tax rate is 15.3 percent: 12.4 percent for Social Security and 2.9 percent for Medicare. You calculate it on your net earnings — what you made minus your business expenses — not on the full 1099 amount. You can deduct half of what you pay in self-employment tax from your income tax, which reduces the total tax you owe.

Your regular income tax on top of self-employment tax depends on your total income for the year and your tax bracket. The IRS does not set a single percentage for income tax the way it does for self-employment tax. Two people earning the same 1099 income can owe different amounts of income tax based on other income they have, their filing status, and deductions they claim.

Key Takeaways

• Self-employment tax is 15.3 percent of your net 1099 earnings, calculated after you subtract business expenses.
• Income tax on 1099 money varies by your total income and tax bracket, not by a fixed percentage.
• You can deduct half of your self-employment tax payment from your income, which lowers your overall tax bill.
• Quarterly estimated tax payments are usually required if you expect to owe $1,000 or more in taxes for the year.
• The 1099 issuer does not withhold taxes, so you are responsible for setting money aside and paying on your own schedule.

How self-employment tax is calculated step by step

Start with the total amount on your 1099. Subtract all business expenses you paid during the year — supplies, equipment, mileage, home office, software, anything directly tied to earning that income. The result is your net earnings.

Multiply your net earnings by 92.35 percent. This accounts for the fact that you can deduct half of your self-employment tax, and the IRS lets you calculate that deduction upfront. Take that number and multiply it by 0.153 (the 15.3 percent rate). That is your self-employment tax.

You report this on Schedule SE, a form you file with your tax return. The IRS uses Schedule SE to calculate how much self-employment tax you owe and to figure out the deduction you can take on your main tax return.

Income tax is separate from self-employment tax

After you know your self-employment tax, you calculate income tax on your net earnings using the standard tax brackets. For 2024, if you are single and your net 1099 income is $11,600, you fall into the 12 percent bracket. If your net income is $47,150, you move into the 22 percent bracket. These brackets change every year.

Your income tax also depends on whether you have other income — a W-2 job, investment income, or a spouse's income if you file jointly. If you have a W-2 job and 1099 income, the 1099 income is taxed on top of your W-2 income, which can push you into a higher bracket.

You can reduce your income tax by claiming the standard deduction (a flat amount based on your filing status) or by itemizing deductions. Many 1099 workers also claim a home office deduction or deduct a portion of their health insurance premiums, which lowers their taxable income.

Quarterly estimated tax payments

Because no employer withholds taxes from a 1099 payment, you are responsible for paying the IRS throughout the year instead of waiting until April. If you expect to owe $1,000 or more in federal taxes, the IRS requires you to make quarterly estimated tax payments.

Quarterly payments are due on April 15, June 15, September 15, and January 15 of the following year. You calculate each payment by estimating your total income, expenses, and tax for the full year, then dividing by four. If your income is uneven across the year, you can adjust each quarter's payment to match what you actually earned.

You can pay estimated taxes online through the IRS website, by mail, or through your bank. If you underpay, you may owe a penalty. If you overpay, the IRS refunds the difference when you file your return.

State and local taxes on 1099 income

In addition to federal self-employment and income tax, you may owe state income tax and local taxes depending on where you live and work. Some states have no income tax. Others tax 1099 income at rates ranging from about 1 percent to over 13 percent, depending on your income level.

A few states also require self-employment tax payments similar to federal self-employment tax. California, for example, taxes self-employment income but does not have a separate self-employment tax — it is included in the state income tax calculation. New Jersey has a self-employment tax on top of income tax.

If you work in a city with a local income tax — such as New York City, Philadelphia, or Columbus — you may owe local tax as well. Check your state and local tax authority websites to understand what you owe where you live and work.

Deductions that lower your 1099 tax bill

The more business expenses you deduct, the lower your net earnings and the less self-employment and income tax you owe. Common deductions for 1099 workers include office supplies, software subscriptions, equipment, mileage, meals and entertainment related to business, professional development, and a portion of your home if you have a dedicated workspace.

You can deduct half of your self-employment tax payment directly on your tax return, which reduces your taxable income. This is automatic — you do not need to itemize or meet any threshold.

If you are self-employed, you can also deduct health insurance premiums you pay yourself, contributions to a SEP-IRA or Solo 401(k), and half of your self-employment tax. Keep receipts and records for all expenses you claim, because the IRS may ask to see them if you are audited.

How a 1099 differs from a W-2 in tax treatment

A W-2 employee has taxes withheld from each paycheck by their employer. The employer also pays half of Social Security and Medicare taxes. By the time you file your return, most or all of your tax obligation is already paid.

A 1099 worker receives the full payment with no withholding. You are responsible for calculating and paying both your income tax and self-employment tax on your own schedule. This means you have more control over deductions and timing, but also more responsibility to set money aside and pay on time.

A 1099 worker can also deduct business expenses that a W-2 employee cannot. W-2 employees can only deduct unreimbursed work expenses if they itemize deductions and meet a high threshold. A 1099 worker deducts expenses directly from income before calculating tax.

Frequently Asked Questions

Do I have to pay quarterly estimated taxes if I only have one 1099?

Only if you expect to owe $1,000 or more in federal taxes for the year. If your 1099 income is small or you have other income with withholding that covers most of your tax bill, you may not be required to pay quarterly. Calculate your expected total tax for the year to know whether you must pay quarterly.

What happens if I do not pay quarterly estimated taxes?

The IRS charges a penalty on the amount you underpaid each quarter. The penalty rate changes quarterly and is based on the federal interest rate. If you owe a large amount and pay it all when you file your return, the penalty can be significant. Paying quarterly, even if your estimate is not perfect, usually costs less than paying everything at once.

Can I deduct my home office if I work from home on a 1099?

Yes. You can use the simplified method (deduct $5 per square foot, up to 300 square feet) or calculate actual expenses like rent, utilities, and internet. You must have a dedicated space used regularly and exclusively for work. Keep records of your home office square footage and expenses in case the IRS asks.

If I receive multiple 1099s, do I add them all together for tax purposes?

Yes. You report all 1099 income on your tax return and calculate self-employment tax on the combined total of your net earnings from all sources. Each 1099 issuer reports only their portion to the IRS, but you are responsible for reporting all of it, even if you receive 1099s from multiple companies.

Is the 15.3 percent self-employment tax the same every year?

The rate stays at 15.3 percent, but there is a cap on the Social Security portion. In 2024, you pay the 12.4 percent Social Security tax only on earnings up to $168,600. Earnings above that amount are not subject to Social Security tax, though they are still subject to the 2.9 percent Medicare tax. The cap changes each year based on wage growth.
