Independent Contractor Tax Forms: W-9, 1099-NEC, and How They Work Together

When you work as an independent contractor, two forms drive most of your tax paperwork: the W-9 you hand to clients before you get paid, and the 1099-NEC you receive after the year closes. For a broader look at how all 1099 variants fit together, see 1099 Tax Form.

The W-9: Your Starting Point With Every New Client

The W-9 gives your client the taxpayer information they need before they can issue you a 1099-NEC — see W-9 Form for a complete walkthrough.

If you skip the W-9, your client is required to apply backup withholding — holding back 24% of each payment and sending it to the IRS — until you provide the form.

The 1099-NEC: What You Receive After the Year Ends

If a client paid you $600 or more for services during the calendar year, they're required to send you a 1099-NEC by January 31. Box 1 (nonemployee compensation) flows to Schedule C; net profit is then subject to self-employment tax at 15.3%. For how the $600 threshold works across entity types, see 1099-Nec Vs 1099-Misc.

Before filing, verify Box 1 against your own records — payers occasionally misreport, and the IRS receives Copy A directly, so a mismatch can trigger an automated notice. For deeper guidance on reconciling 1099 figures, see the 1099-Misc Form reference.

How to Issue a 1099 to an Individual

If you run a business and paid a contractor $600 or more during the year, the obligation runs the other direction: you're the one issuing the form. The process has four concrete steps.

• Collect a completed W-9 before the first payment — chasing it in January is the most common mistake payers make.
• Track payments across the full calendar year — the $600 threshold is an annual total across all transactions with that individual, not per invoice. Full threshold rules are at 1099 Nec Threshold 2025.
• Confirm the recipient qualifies — the 1099-NEC applies to individuals, sole proprietors, and single-member LLCs, but generally not C-corps or S-corps. Full entity-type rules are in the 1099 Nec Threshold 2025 guide.
• File Copy A with the IRS and send Copy B to the contractor by January 31. Filing late triggers penalties that scale with the length of the delay.

If the payment was for rent, royalties, or prizes rather than contractor services, a different form applies. See 1099-Nec Vs 1099-Misc for which form covers which payment type and what the deadline differences are.

Planning Around the Tax You'll Owe

Because no employer withholds taxes from contractor payments, the IRS generally expects quarterly estimated payments if you'll owe $1,000 or more annually. For how 1099 income feeds into your overall tax liability, see 1099 Tax Form.
