How to Fill Out Form 1099-NEC: Box-by-Box Instructions and Deadlines

To fill out Form 1099-NEC, collect a completed W-9 from each independent contractor you paid $600 or more during the year, enter your business name, address, and EIN in the payer block, enter the contractor’s name, address, and taxpayer identification number in the recipient block exactly as shown on their W-9, put the total nonemployee compensation in Box 1, and file Copy A with the IRS while sending Copy B to the contractor by January 31.¹ The form itself is short. The parts that trip businesses up are the numbers going into Box 1, the copies going to the right places, and the deadline.

What You Need Before You Start

Three pieces of information have to be in front of you: the contractor’s details, your own business details, and a clean payment total.

A Signed W-9 From the Contractor

IRS Form W-9 is the source document for everything you put in the recipient block. It gives you the contractor’s legal name, business name, address, entity type, and taxpayer identification number, which can be a Social Security number, an EIN, or an ITIN.² Ask for it before you make the first payment. Keep the completed W-9 in your files and don’t send it to the IRS — the form says so at the top.

The W-9 also tells you the contractor’s entity type, which is how you know whether you owe a 1099-NEC at all. Payments to C-corporations and S-corporations (including LLCs taxed as corporations) generally don’t require a 1099-NEC. The exception is attorneys: legal fees are reportable no matter how the law firm is organized.³

Your Own Business Information

You’ll need your full legal business name, mailing address, and EIN. The name and EIN must match what you use on your other IRS filings. A sole proprietor without an EIN uses their Social Security number in place of one.

A Clean Payment Total

Add up every reportable payment to the contractor during the calendar year. Two things routinely throw the total off.

First, expense reimbursements. If the contractor gave you an adequate accounting for travel or other business expenses — receipts, dates, business purpose — exclude the reimbursed amounts. If they didn’t, roll the reimbursements into the total reported in Box 1.⁴

Second, payment method. Exclude anything you paid by credit card, debit card, or a third-party processor like PayPal or Venmo. Those go on Form 1099-K, filed by the processor, and reporting them again on a 1099-NEC would double-count the income.³ Include payments by check, cash, ACH, and wire.

Filling Out the Form, Box by Box

The top of the form is identification. The numbered boxes below are the financial detail.

In the upper-left area, enter your business name, address, phone number, and TIN (usually your EIN). In the upper-right area, enter the contractor’s name, address, and TIN exactly as they appear on the W-9. A mismatch between the name and TIN is one of the most common errors and can trigger an IRS notice or a penalty. The IRS offers a free TIN Matching service that lets you verify name-and-TIN combinations before you file, which is worth using if you’re filing for more than one or two contractors.⁵

Box 1: Nonemployee Compensation

This is the main box. Enter the total dollar amount you paid the contractor during the calendar year for services. It should match your accounting records and include fees, commissions, and any expense reimbursements that weren’t properly accounted for.³

Box 2: Direct Sales of $5,000 or More

Box 2 is a checkbox, not a dollar figure. Check it only if you sold $5,000 or more in consumer products to the recipient on a buy-sell or commission basis for resale outside a permanent retail establishment. Most businesses paying contractors for services leave it blank.⁶

Box 4: Federal Income Tax Withheld

Leave this blank in almost every case. You only enter an amount here if you withheld federal income tax under the backup withholding rules, which are covered further down. Contractors normally handle their own income taxes.

Boxes 5 Through 7: State Information

Box 5 is any state income tax you actually withheld. Box 6 is your state tax identification number. Box 7 is the amount of income subject to state tax, which usually matches Box 1. Many states don’t require withholding from contractor payments, so these often stay blank.

Which Copies Go Where

Each 1099-NEC prints in multiple copies, and they don’t all go to the same place.

Copy A goes to the IRS. If you’re filing on paper, it must be the official red-ink scannable version. Photocopies and PDF printouts won’t scan.
Copy B goes to the contractor for their tax return.
Copy C stays in your records.
Copies 1 and 2 go to the contractor for state and local filings, when applicable.

Filing Deadlines and Methods

The deadline for the 1099-NEC is January 31 following the calendar year of payment, for both Copy A to the IRS and Copy B to the contractor. There is no automatic extension, and unlike the 1099-MISC there’s no later electronic-filing deadline. If January 31 falls on a weekend or holiday, the due date moves to the next business day.⁶

Electronic Filing

If you file 10 or more information returns of any type during the year — counting your W-2s, 1099-NECs, 1099-MISCs, and other information returns together — you have to file electronically.⁷ The IRS runs a free web portal called the Information Returns Intake System (IRIS) that lets you key forms in manually or upload them in bulk, file them, and download copies to distribute.⁸

Paper Filing

If you’re under the 10-return threshold, you can file on paper. Mail the red-ink Copy A of each 1099-NEC along with Form 1096, the transmittal summary that has to accompany any batch of paper information returns sent to the IRS.⁹

Getting Copy B to the Contractor

Copy B has to reach the contractor by the same January 31 deadline. Mail is fine. Electronic delivery is also allowed, but only with the contractor’s written consent given in advance, and before you get that consent you have to tell them they can request a paper copy, explain how to withdraw consent, and confirm they have the hardware and software to open the electronic version.¹⁰ Keep proof of mailing or delivery.

State Filing

Many states want their own copy filed with the state tax department. Some states get their data through the IRS Combined Federal/State Filing Program, but that doesn’t always eliminate a direct state filing. Check your state’s Department of Revenue for its specific requirements and deadlines.

Fixing a Mistake After You File

If you catch an error after filing — a wrong amount, an incorrect TIN, a misspelled name — file a corrected 1099-NEC. Electronic filers use the correction procedures inside IRIS or FIRE. Paper filers submit a new form with the corrected information. Do not check the “VOID” box on the corrected form. Checking VOID tells the IRS scanners to ignore the form entirely, so the correction never lands.⁶ Send a corrected Copy B to the contractor as well.

When Backup Withholding Changes the Form

Backup withholding is the situation that puts a number in Box 4. It applies at a flat 24% rate when a specific problem arises with the contractor.¹¹ You must begin withholding when:

The contractor fails to give you a TIN.
The IRS notifies you that the TIN they gave you is incorrect.
The IRS notifies you that the contractor underreported interest or dividends.
The contractor fails to certify on the W-9 that they aren’t subject to backup withholding.

¹² If you withheld, put the withheld amount in Box 4 and deposit the tax using Form 945, the annual return for withheld federal income tax on nonpayroll payments.¹³

Penalties for Filing Late or Wrong

The IRS charges separate penalties for two different failures: not filing the correct form with the IRS on time, and not furnishing the correct statement to the contractor on time. For returns and statements due in 2026, both penalties scale the same way with how late you are:

Up to 30 days late: $60 per form.
31 days late through August 1: $130 per form.
After August 1 or never filed: $340 per form.
Intentional disregard: $680 per form, with no aggregate cap.

¹⁴ Because the penalties apply per form for each type of failure, a single 1099-NEC you never file and never send to the contractor can generate two separate penalties. Multiply across several contractors and the numbers climb fast. The intentional disregard penalty is the harshest: no cap, and it can be the greater of $680 or a percentage of the amount you were supposed to report.¹⁵ Even if you’ve already missed January 31, file as soon as you can. Sixty dollars beats three hundred and forty.

When a 1099-NEC Is the Wrong Form

A few situations look like they call for a 1099-NEC but don’t. You don’t file one for payments totaling under $600 to the contractor for the year. You don’t file one for payments to a corporation, except for legal fees. You don’t file one for anything paid by credit card, debit card, or a third-party processor — the processor reports those on a 1099-K. You don’t file one for purchases of merchandise, freight, or storage, because the form covers services. And you don’t file one for personal payments unconnected to your trade or business.¹

Some payments to non-employees do get reported, but on Form 1099-MISC instead: rent of $600 or more, royalties of $10 or more, prizes and awards not tied to services, and gross proceeds paid to an attorney in connection with legal services (Box 10 of the 1099-MISC, even though attorney fees for services go on the 1099-NEC).⁶
