The difference between a 1099 and a W-9 comes down to direction and timing: a W-9 is the form an independent contractor gives to a business before getting paid, sharing their name and taxpayer ID; a 1099 is the form the business sends to the contractor and the IRS after year-end to report what it paid. One collects information at the start of the relationship, the other reports the money at the end.
Who Fills Out Which Form
The W-9 is filled out by the contractor and kept by the business. It never goes to the IRS.1IRS.gov. Form W-9 (Rev. March 2024) The business uses it as a data source: the contractor’s legal name, address, tax classification, and taxpayer identification number all live on that form so the business has what it needs when tax season arrives.
The 1099 runs the other direction. The business prepares it, sends one copy to the contractor and another to the IRS, and the numbers on it come straight from the W-9 the contractor turned in months earlier. If the W-9 has the wrong Social Security number or a misspelled name, that error carries onto the 1099 and can trigger an IRS notice when the contractor’s return doesn’t match.
When a Business Collects a W-9
A business should request a W-9 before making the first payment to any U.S. contractor, freelancer, or non-employee service provider. Federal law requires the payer to request the payee’s taxpayer identification number for any reportable payment.2Office of the Law Revision Counsel. 26 USC 6109 – Identifying Numbers Waiting until December to chase down W-9s is how filing deadlines get missed.
The form asks the contractor to:
- Provide their legal name as it appears on their tax return, plus any separate business name.
- Check a federal tax classification: individual/sole proprietor, C-corporation, S-corporation, partnership, trust/estate, or LLC (with the LLC’s own tax classification specified).
- Enter their Taxpayer Identification Number, usually a Social Security Number for individuals or an Employer Identification Number for entities.
- Sign under penalty of perjury that the information is accurate and indicate whether they are subject to backup withholding.1IRS.gov. Form W-9 (Rev. March 2024)
That signature is what shifts responsibility for the accuracy of the tax ID from the business to the contractor. If a contractor refuses to provide a W-9 or gives a bad number, the business must begin backup withholding of 24% on every payment and remit that to the IRS until the problem is corrected.3Internal Revenue Service. Backup Withholding
Foreign Contractors Use a Different Form
The W-9 is only for U.S. persons. A non-U.S. individual should complete Form W-8BEN instead; a foreign entity uses W-8BEN-E.4Internal Revenue Service. About Form W-8 BEN, Certificate of Foreign Status of Beneficial Owner for United States Tax Withholding and Reporting (Individuals) If you receive a W-9 request and aren’t a U.S. person, tell the payer and send the correct W-8 form.
When a Business Issues a 1099
After the calendar year ends, the business tallies what it paid each contractor. If the total for a non-employee reaches the reporting threshold, the business issues a Form 1099 that pulls the contractor’s information directly from the W-9 on file. The IRS gets a matching copy, which is how discrepancies between what a payer reported and what a payee reported on their tax return come to light.
For payments to independent contractors for services, the correct form is the 1099-NEC (Nonemployee Compensation).5Internal Revenue Service. About Form 1099-NEC, Nonemployee Compensation
1099-NEC vs. 1099-MISC
The 1099-NEC covers payments for services performed by a non-employee. A graphic designer, a bookkeeper, or a consultant paid above the threshold gets a 1099-NEC.6Internal Revenue Service. Reporting Payments to Independent Contractors
The 1099-MISC covers payments that aren’t for services: rent, royalties, prizes and awards, medical and health care payments, and crop insurance proceeds.7Internal Revenue Service. Instructions for Forms 1099-MISC and 1099-NEC (Rev. April 2025) A landlord receiving rent from a business tenant would get a 1099-MISC, not a 1099-NEC.
Attorney payments split across both. Legal fees for services go on the 1099-NEC. Gross proceeds paid to an attorney in connection with a settlement go on the 1099-MISC.7Internal Revenue Service. Instructions for Forms 1099-MISC and 1099-NEC (Rev. April 2025)
The $2,000 Threshold for 2026 Payments
For payments made after December 31, 2025, businesses must issue a 1099-NEC when total payments to a non-employee reach $2,000 or more during the calendar year. That’s up from the long-standing $600 threshold, changed by amendment to 26 U.S.C. ยง 6041.8Office of the Law Revision Counsel. 26 USC 6041 – Information at Source The same $2,000 threshold now applies to several 1099-MISC categories, including rent and medical payments.9Internal Revenue Service. Form 1099 NEC and Independent Contractors
The threshold only decides whether the business has a filing obligation. Contractors still have to report all income on their tax return, including amounts under $2,000. And the $10 threshold for royalties is unchanged.
The Corporate Exemption
The tax classification the contractor selected on the W-9 tells the business whether a 1099 is needed at all. Payments to C-corporations and S-corporations are generally exempt from 1099 reporting. If the “Corporation” box is checked, the business can typically skip filing.7Internal Revenue Service. Instructions for Forms 1099-MISC and 1099-NEC (Rev. April 2025)
Two exceptions cut through that exemption. Payments to attorneys must be reported even if the law firm is incorporated. So must medical and health care payments to corporations, including professional corporations.7Internal Revenue Service. Instructions for Forms 1099-MISC and 1099-NEC (Rev. April 2025)
Deadlines and Penalties
Both the contractor copy and the IRS copy of Form 1099-NEC are due by January 31 of the year after payment. For 2026 payments, that’s January 31, 2027. Both copies land on the same date.10Internal Revenue Service. Instructions for Forms 1099-MISC and 1099-NEC (04/2025) Businesses filing ten or more information returns in total must file electronically.11IRS.gov. Form 1096 Annual Summary and Transmittal of U.S. Information Returns
Penalties are assessed per form and grow with the delay: $60 per form if corrected within 30 days of the due date, $130 if corrected by August 1, and $340 if filed after August 1 or not at all. Intentional disregard runs $690 per form with no annual cap.12Internal Revenue Service. Information Return Penalties And these penalties can apply twice on the same missed 1099: once for the IRS filing failure and once for failing to furnish the contractor’s copy.
If You Received a 1099
Getting a 1099-NEC changes how you owe tax on that income. As an employee, your employer covers half of Social Security and Medicare. As an independent contractor, you owe both halves yourself, a combined rate of 15.3%.13Social Security Administration. 2026 Cost-of-Living Adjustment (COLA) Fact Sheet That’s 12.4% for Social Security on earnings up to $184,500 in 2026, plus 2.9% Medicare with no cap.14Social Security Administration. What Is the Current Maximum Amount of Taxable Earnings for Social Security Net self-employment income above $200,000 (or $250,000 for joint filers) carries an additional 0.9% Medicare surtax on the excess.
You can deduct half of the self-employment tax when calculating adjusted gross income, which reduces your income tax but not the self-employment tax itself.15Internal Revenue Service. Topic No. 554, Self-Employment Tax
Quarterly Estimated Payments
Since no employer is withholding taxes from your 1099 income, you pay estimated taxes yourself, four times a year. For 2026, the deadlines are April 15, June 15, and September 15 of 2026, plus January 15, 2027.16IRS.gov. 2026 Form 1040-ES Estimated Tax for Individuals You can skip the January payment if you file the full return and pay any balance by February 1, 2027. Missing the deadlines or underpaying triggers an estimated tax penalty that functions like interest.
Overlap With Form 1099-K
If clients pay you through PayPal, Venmo, or a credit card processor, the platform may also send you a 1099-K covering those same payments. The 1099-K threshold reverted to $20,000 in gross payments and more than 200 transactions per year.17Internal Revenue Service.
