How to fill out a 1099: a field-by-field walkthrough for payers

Who this page is for

This walkthrough is for bookkeepers, accountants, and business owners preparing Forms 1099-NEC. It covers the completion workflow: where each entry comes from, how names and TINs are entered, how paper copies are handled, and how the completed form moves to filing. For threshold analysis, the broader box-layout overview, and the electronic filing landscape, use our Form 1099-NEC instructions orientation.

Before you start: the W-9 and payment records

The Form W-9 supplies the payee-side information used on the return: the name, any business name, address, taxpayer identification number, and federal tax classification (https://www.irs.gov/forms-pubs/about-form-w-9, https://www.irs.gov/instructions/i1099gi). The IRS permits electronic Form W-9 collection systems that meet the General Instructions' requirements (https://www.irs.gov/instructions/i1099gi).

Your payment records supply the amount paid during the payment year. Remove amounts paid by credit card, payment card, or through a third-party payment network when the payment settlement entity reports those transactions on Form 1099-K (https://www.irs.gov/instructions/i1099mec, https://www.irs.gov/forms-pubs/about-form-1099-k). Keep this review at the payment-channel level. Form 1099-K dollar thresholds require separate, current primary-source verification.

Collecting the W-9 during onboarding reduces missing-name and missing-TIN cleanup during filing season. Our guide to requesting a W-9 from a vendor covers that workflow.

Complete the payer fields

Enter the payer's legal name, address, and TIN so the name and TIN match the payer information used on its other federal tax returns (https://www.irs.gov/instructions/i1099gi). A sole proprietor may use an SSN when the proprietor is not otherwise required to have an EIN (https://www.irs.gov/instructions/i1099gi).

For a single-member LLC that is disregarded as separate from its owner, enter the owner's name on the first name line and the LLC's name on the second line (https://www.irs.gov/instructions/i1099gi).

Complete the recipient fields

Use the completed W-9 and the recipient-name rules in the General Instructions (https://www.irs.gov/instructions/i1099gi).

For a sole proprietor, enter the individual's name on the first name line. A trade name or doing-business-as name may go on the second line. A trade name by itself is insufficient. The IRS prefers the proprietor's SSN, although the sole proprietorship's EIN is also acceptable (https://www.irs.gov/instructions/i1099gi).

For a single-member LLC that is disregarded as separate from its owner, enter the owner's name on the first line, the LLC's name on the second line, and the owner's TIN. An LLC taxed as a corporation or partnership uses the entity's name and EIN (https://www.irs.gov/instructions/i1099gi). Our LLC reporting guide explains how federal tax classification affects the reporting analysis.

Enter one recipient TIN. On paper forms, SSNs, ITINs, and ATINs use two hyphens, while EINs use one hyphen (https://www.irs.gov/instructions/i1099gi). When the payee did not provide a TIN, leave the TIN box blank instead of entering zeros. Backup withholding can apply when a payee fails to provide a correct TIN (https://www.irs.gov/instructions/i1099gi, https://www.irs.gov/businesses/small-businesses-self-employed/backup-withholding).

Complete the account number box when you file more than one information return of the same type for the same recipient. Use a unique number that distinguishes the account (https://www.irs.gov/instructions/i1099gi).

Enter the payment amounts

For payments made in 2025 and reported in early 2026, use the Rev. April 2025 form instructions for the payment-year layout (https://www.irs.gov/pub/irs-prior/i1099mec--2025.pdf).

Enter the 2025 nonemployee compensation amount in box 1. The 2025 instructions include fees, commissions, prizes and awards for services, directors' fees, and attorneys' fees for legal services in that field. Attorneys' fees for legal services can be reportable even when the law firm is incorporated. Cash purchases of fish for resale do not belong in this field (https://www.irs.gov/pub/irs-prior/i1099mec--2025.pdf).

For direct sales made in 2025, box 2 is a checkbox when sales of consumer products for resale totaled $5,000 or more during 2025. Do not enter a dollar amount in the checkbox (https://www.irs.gov/pub/irs-prior/i1099mec--2025.pdf).

Box 3 carries excess golden parachute payments, box 4 carries federal income tax withheld under the backup withholding rules, and boxes 5 through 7 carry state information under the 2025 payment-year layout (https://www.irs.gov/pub/irs-prior/i1099mec--2025.pdf). When backup withholding occurred, report it without applying the ordinary nonemployee-compensation payment threshold (https://www.irs.gov/pub/irs-prior/i1099mec--2025.pdf).

On paper forms, use black type, include the decimal point and cents, omit dollar signs, and leave unused money boxes blank instead of entering zero (https://www.irs.gov/instructions/i1099gi).

Prepare the copies and Form 1096

For a paper filing, send Copy A to the IRS with Form 1096. Use a separate Form 1096 for each type of information return included in the paper submission (https://www.irs.gov/instructions/i1099gi). The remaining copies go to the recipient, the applicable state when required, and the payer's records (https://www.irs.gov/instructions/i1099gi).

Do not file Copy A printed from the IRS website. The IRS requires an official scannable Copy A for paper filing, and photocopies are unacceptable (https://www.irs.gov/instructions/i1099gi). Order official forms at https://www.irs.gov/orderforms. The online recipient copies may be printed and used for recipient statements (https://www.irs.gov/instructions/i1099gi).

Do not cut or separate Copies A that are printed multiple to a sheet. Submit the full page, and do not staple the forms to Form 1096 (https://www.irs.gov/instructions/i1099gi).

The recipient statement must show a telephone number for a person who can answer questions about the statement (https://www.irs.gov/instructions/i1099gi). The payee's TIN may be truncated on the payee statement so that only the last four digits appear. Do not truncate the payee TIN on a copy filed with the IRS, and do not truncate the filer's TIN on any copy (https://www.irs.gov/instructions/i1099gi).

Complete the filing handoff

For 2025 payments, Form 1099-NEC is due to the IRS and the recipient on February 2, 2026 because January 31 falls on a weekend. For 2025 Form 1099-MISC filings, the IRS filing dates are March 2, 2026 on paper and March 31, 2026 electronically (https://www.irs.gov/instructions/i1099gi).

The 1099 filing deadlines calendar keeps the federal filing, recipient-statement, extension, Form 945, and IRIS transition dates in one season-specific reference.

The 2025 General Instructions do not provide an automatic extension for filing Form 1099-NEC (https://www.irs.gov/instructions/i1099gi). This page does not cover extension procedures.

For 2025 payment-year returns filed in 2026, electronic filing is required when the filer must submit 10 or more information returns in aggregate across the covered return types (https://www.irs.gov/instructions/i1099mec, https://www.irs.gov/instructions/i1099gi). When an original return was required to be filed electronically, a correction to that return must also be filed electronically (https://www.irs.gov/instructions/i1099gi). The Form 1099-NEC instructions orientation covers the electronic filing landscape.

What this page does not cover

This page leaves threshold depth, the broader box-layout overview, and IRIS detail to the Form 1099-NEC instructions orientation. For correction procedures, use our corrected 1099 guide. This page does not cover late-filing penalty amounts or extension procedures. Use the official General Instructions for those topics (https://www.irs.gov/instructions/i1099gi).
