A 1099 form reports income you earned as a contractor, not as an employee

When you work for a company but are not on their payroll, they report what they paid you on a 1099 form instead of a W-2. The company sends you a copy, sends a copy to the IRS, and files a copy with the Social Security Administration. The form shows your name, address, tax ID (usually your Social Security number), and the total amount paid to you during the year. You then report that income on your tax return.

The key difference from a W-2 is that no taxes are withheld from your pay. The company does not take out federal income tax, Social Security tax, or Medicare tax. You are responsible for paying those taxes yourself, either through quarterly estimated tax payments or when you file your annual return. The company's only obligation is to report what they paid you.

Different types of 1099 forms exist for different kinds of income. The most common is the 1099-NEC (Miscellaneous Income), which reports payments for services. A 1099-MISC reports other types of income like royalties or rents. A 1099-INT reports interest income, and a 1099-DIV reports dividends. This guide focuses on 1099-NEC, which is what most contractors receive.

Key Takeaways

  • A company files a 1099-NEC to report money paid to you for work, and you must report that income on your tax return even if you do not receive the form by tax day.
  • No taxes are withheld from 1099 income, so you owe federal income tax, Social Security tax, and Medicare tax on the full amount reported.
  • You can deduct business expenses (supplies, equipment, a home office) from your 1099 income to lower your taxable profit.
  • The IRS matches the 1099 the company files with the one you report on your return, so mismatches trigger audits or notices.
  • A company must file a 1099-NEC for any contractor they paid $600 or more during the year, though some industries have different thresholds.

When a company must file a 1099-NEC for you

A business files a 1099-NEC when they pay you $600 or more in a calendar year for services. This threshold applies to most industries. However, payments for medical and health care services, and payments made through a credit card or payment app, have different rules — those must be reported even if the amount is under $600.

The company must send you a copy of the 1099-NEC by January 31 of the following year. They file the same form with the IRS and the Social Security Administration by the same date. If you do not receive a 1099-NEC by early February, contact the company and ask them to send it or confirm they filed it. If they say they did not file one, ask why — they may have misclassified you as an employee, or they may have paid you less than $600 and were not required to file.

You are responsible for reporting 1099 income on your tax return whether or not you receive the form. If the company filed it with the IRS but did not send you a copy, the IRS will have a record of it. If you do not report it, the IRS will notice the mismatch and send you a notice or bill.

How 1099 income affects your tax bill

1099 income is taxed as self-employment income. You owe federal income tax on the profit (income minus deductible expenses), plus self-employment tax, which covers Social Security and Medicare. Self-employment tax is 15.3 percent of your net profit — 12.4 percent for Social Security and 2.9 percent for Medicare. You also owe state income tax if your state has one.

Because no taxes are withheld, you may owe a large bill when you file your return. Many contractors make quarterly estimated tax payments to avoid this. You calculate what you expect to earn, estimate your tax bill, and send it to the IRS four times a year (April, June, September, and January). The IRS provides a worksheet to help you calculate the amount.

If you underpay your estimated taxes, you may owe a penalty when you file. If you overpay, you receive a refund. The goal is to pay roughly what you will owe so there is no large surprise at tax time.

What business expenses you can deduct from 1099 income

You can subtract business expenses from your 1099 income to lower the amount you owe tax on. Common deductions include supplies, equipment, software subscriptions, vehicle mileage (if you use your car for work), home office space, and professional services like accounting or legal fees. You can only deduct expenses that are ordinary and necessary for your work — personal expenses do not count.

Keep receipts and records for everything you deduct. The IRS does not require you to attach them to your return, but you must have them if the IRS asks. A straightforward spreadsheet or folder of receipts is enough. If you claim a home office, you can use either the actual expense method (deduct a percentage of rent, utilities, and repairs based on the square footage of your office) or the simplified method (deduct $5 per square foot, up to 300 square feet).

The difference between your 1099 income and your deductible expenses is your net profit. That is the amount you owe income tax and self-employment tax on. If your expenses exceed your income in a year, you have a loss, which you can carry forward to reduce taxes in future years.

How the IRS matches your 1099 to your tax return

When you file your tax return, you report your 1099 income on Schedule C (Profit or Loss from Business). The IRS receives the same 1099 from the company and compares the two. If the amounts match, nothing happens. If they do not match — for example, you reported $8,000 but the company reported $10,000 — the IRS sends you a notice asking why.

A mismatch can happen for several reasons. You may have made an error when entering the amount. The company may have made an error on the 1099. You may have received a corrected 1099 (called a 1099-X) after filing your return. Or the company may have reported a payment you did not actually receive. Whatever the reason, the IRS will ask you to explain or pay the difference.

If you receive a notice, do not ignore it. Respond with documentation — a copy of your 1099, a bank statement showing the actual payment, or a letter from the company explaining the error. If the company made the mistake, ask them to file a corrected 1099-X. The IRS will update their records once they receive it.

Corrected 1099 forms and what to do if yours is wrong

If a company discovers they filed a 1099-NEC with the wrong amount, they file a corrected form called a 1099-X. They send you a copy and file it with the IRS. You do not need to amend your tax return just because you received a 1099-X — the IRS will match the corrected form to your return. However, if the correction changes your reported income significantly, you may want to file an amended return to make sure your tax bill is correct.

If you received a 1099-NEC with an error — for example, the wrong Social Security number or an amount you did not earn — contact the company when ready and ask them to send a corrected 1099-X. Do not wait until tax time. The sooner they correct it, the less likely you are to have problems with the IRS.

If a company refuses to correct an obvious error, you can file your return with the correct amount and include a note explaining the discrepancy. Keep documentation of your communication with the company. If the IRS contacts you, you can show them the evidence.

1099 income and self-employment tax explained

Self-employment tax is the Social Security and Medicare tax that employees and employers normally split. When you are self-employed, you pay both halves — 15.3 percent of your net profit. This is in addition to federal income tax. For example, if you earn $50,000 in 1099 income and have $10,000 in deductible expenses, your net profit is $40,000. You owe federal income tax on $40,000 (the rate depends on your total income and filing status) plus self-employment tax of about $5,656.

You report self-employment tax on Schedule SE (Self-Employment Tax), which is part of your tax return. The form calculates how much you owe. You can deduct half of your self-employment tax from your income before calculating federal income tax, which reduces your overall tax bill slightly.

If you have multiple 1099s from different companies, you add them all together and pay self-employment tax on the total. If you also have W-2 income from an employer, you do not pay self-employment tax on that — your employer already withheld Social Security and Medicare tax.

Frequently Asked Questions

Do I have to report 1099 income if I did not receive the form?

Yes. You must report all income you earned, whether or not you receive a 1099. If the company filed it with the IRS but did not send you a copy, the IRS will have a record of it. If you do not report it on your return, the IRS will notice and send you a bill or notice.

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

Yes, if you have a net loss from self-employment, you can use it to reduce your overall taxable income. You report the loss on Schedule C, and it flows through to your main tax return. This can lower your federal income tax bill, though the rules are complex if your loss is large.

What if a company paid me in cash and did not give me a 1099?

You still owe tax on it. Cash income is taxable whether or not it is reported to the IRS. If you have no documentation, keep a record of when and how much you were paid. If the IRS asks, you can show your bank deposits or other evidence of the income.

Do I need to file quarterly estimated taxes if I have 1099 income?

Not required, but recommended. If you do not pay estimated taxes and owe more than $1,000 when you file your return, you may owe a penalty. Quarterly payments help you avoid a large bill and a penalty. Use IRS Form 1040-ES to calculate what to pay.

What happens if the 1099 amount is higher than what I actually earned?

Contact the company and ask them to file a corrected 1099-X. If they refuse or do not respond, report the correct amount on your tax return and include a note explaining the discrepancy. Keep documentation of your communication with the company in case the IRS asks.
