A 1099 is a record of income you earned that wasn't subject to payroll withholding

A 1099 form reports money you received for work or services where you were not an employee on a company's payroll. Instead of your employer withholding taxes from each paycheck, you received the full amount and are responsible for paying taxes on it yourself. The IRS receives a copy of every 1099 issued to you, so the income must be reported on your tax return.

The most common type is the 1099-NEC (Nonemployee Compensation), which reports payments for services. A 1099-MISC (Miscellaneous Income) covers other types of payments like rent, royalties, or prizes. There are also specialized forms like the 1099-INT for interest income or 1099-DIV for dividends. Each one tells the IRS a different category of income you received.

You are typically sent a 1099 by January 31 of the year following the one in which you earned the income. The company or person who paid you must also send a copy to the IRS. This is why it matters: the IRS already knows about that income before you file your return.

Key Takeaways

  • A 1099 reports income paid to you without payroll withholding, and the IRS receives a copy automatically.
  • The 1099-NEC is used for self-employment and contract work; the 1099-MISC covers rent, royalties, and other miscellaneous payments.
  • You must report all 1099 income on your tax return, even if you did not receive the form or disagree with the amount.
  • Income reported on a 1099 is subject to self-employment tax (Social Security and Medicare), which can be significantly higher than payroll tax.
  • Keeping records of expenses related to 1099 income can reduce your taxable profit through deductions for supplies, equipment, and home office use.

How 1099 income differs from W-2 wages

When you receive a W-2, your employer withheld federal income tax, Social Security tax, and Medicare tax from your paychecks throughout the year. Your employer also paid half of your Social Security and Medicare taxes on your behalf. A 1099 means none of that happened—you kept all the money, but you owe all the taxes.

This creates two major differences. First, you must pay self-employment tax, which covers both the employee and employer portions of Social Security and Medicare. For 2024, that is 15.3% of your net self-employment income (12.4% for Social Security on income up to a cap, plus 2.9% for Medicare on all income). Second, you do not have taxes withheld automatically, so you may owe a large amount when you file unless you make quarterly estimated tax payments.

A W-2 employee earning $50,000 might owe roughly $6,000 in federal income tax plus payroll taxes already withheld. A 1099 contractor earning the same gross amount owes federal income tax plus self-employment tax of around $7,065, and must pay it in installments or in full at tax time.

What you must report on your tax return

Every 1099 you receive must be reported on your tax return. The IRS matches the 1099s they receive from payers against the income you report. If you do not report a 1099, the IRS will notice the mismatch and may send you a notice demanding payment plus penalties and interest.

If you received a 1099 but believe the amount is wrong, report what you actually received and keep documentation of the error. If the payer issued a corrected form (a 1099-X), report the corrected amount instead. Do not straightforward ignore a 1099 you disagree with; that creates a compliance problem with the IRS.

1099 income is reported on Schedule C (Profit or Loss from Business) if you are self-employed, or on the appropriate line of your Form 1040 if it is investment or other income. The form you use depends on the type of 1099 and your situation.

Deductions you can claim against 1099 income

One major advantage of 1099 income is that you can deduct legitimate business expenses, which reduces the amount of income you owe tax on. If you earned $60,000 on a 1099 but had $15,000 in deductible expenses, you owe tax on $45,000 of profit instead.

Common deductions for 1099 contractors include supplies and materials, equipment (subject to depreciation rules), vehicle mileage if you use your car for business, home office expenses, professional services like accounting or legal fees, and health insurance premiums if you are self-employed. You must keep receipts and records showing what the expenses were and that they were ordinary and necessary for your work.

The home office deduction is available if you use part of your home regularly and exclusively for business. You can deduct either a simplified rate (currently $5 per square foot, up to 300 square feet) or actual expenses like rent, utilities, and insurance allocated to that space. This deduction is common for people who work from home on 1099 contracts.

Quarterly estimated tax payments and planning

If you expect to owe more than $1,000 in federal income tax for the year, you should make quarterly estimated tax payments to avoid penalties. These are due on April 15, June 15, September 15, and January 15 of the following year. You calculate them based on your expected annual income and file Form 1040-ES with the IRS.

Underestimating your quarterly payments can result in an underpayment penalty, even if you ultimately owe no tax or get a refund. The penalty is calculated based on how much you underpaid and when. Making quarterly payments also spreads the tax burden across the year rather than creating a large bill in April.

If your 1099 income is irregular or you are unsure how much to pay, a tax professional can help you calculate the right amount. Some people set aside a percentage of each 1099 payment (often 25% to 30%) in a separate account to cover taxes and quarterly payments.

What to do if you did not receive a 1099

If someone paid you $600 or more for services and did not send you a 1099-NEC by January 31, you still owe tax on that income. The threshold for 1099-MISC varies by type of payment. You must report the income whether or not you have a form.

Contact the payer and ask for the 1099. If they do not send it, you can file Form 8275 (Disclosure Statement) with your return explaining that you reported income without a corresponding 1099. Keep any documentation you have—emails, invoices, bank deposits—showing the payment was made and what it was for.

If the payer issued a 1099 to the IRS but sent it to the wrong address and you never received it, the IRS will still have it on file. You will discover this when you file your return or receive a notice. Report the income on your return to match what the IRS already knows about.

State and local tax obligations

In addition to federal taxes, 1099 income is subject to state income tax in most states and local income tax in some cities. Some states have a lower threshold than the federal $600 for issuing a 1099, and some require 1099s for payments to corporations or LLCs even if the federal threshold is not met.

You may also owe self-employment tax to your state. Some states tax self-employment income at the same rate as wages; others have a separate calculation. A few states have no income tax at all. Your state tax return will ask about 1099 and self-employment income, and you should report it consistently with your federal return.

If you work in multiple states, you may owe tax in each one. This is especially common for remote contractors or people who travel for work. A tax professional familiar with your state can advise on filing requirements and whether you can claim credits for taxes paid to other states.

Frequently Asked Questions

Do I have to report a 1099 if I did not make a profit?

Yes. You must report all 1099 income on your return. If your expenses exceeded your income, you report a loss, which can offset other income or carry forward to future years. The IRS still needs to see the income reported.

What happens if the 1099 amount is wrong?

Report the actual amount you received and keep documentation of the error. If the payer issues a corrected 1099-X, report that instead. If the IRS contacts you about a mismatch, you can provide evidence of what you actually earned. Do not ignore the discrepancy.

Can I deduct business losses from 1099 income against my W-2 wages?

Yes. If you have a loss from self-employment on Schedule C, it reduces your overall taxable income for the year. This can lower your federal income tax bill even if you also have W-2 wages. State rules vary, so check your state's treatment of business losses.

Am I required to have a business license or register as self-employed to report 1099 income?

Federal tax law does not require a business license to report 1099 income. However, some states and cities require registration or a license if you are operating a business. Check your local requirements. You must report the income on your federal return regardless of licensing status.

What is the difference between a 1099-NEC and a 1099-MISC?

A 1099-NEC reports nonemployee compensation for services (freelance work, consulting, contract labor). A 1099-MISC covers miscellaneous income like rent, royalties, prizes, or payments for use of property. The type of 1099 depends on what the payment was for, not your choice.
