What Paperwork Do I Need for a 1099 Employee?

The paperwork needed for a 1099 employee comes down to four things: a completed Form W-9 collected before you pay anything, a signed independent contractor agreement, clean records of every invoice and payment, and Form 1099-NEC filed at year’s end for any contractor who crossed the reporting threshold. For tax year 2026, that threshold rose from $600 to $2,000, so fewer contractors will trigger a 1099-NEC than in past years.¹ One quick note on terminology: a “1099 employee” isn’t actually an employee. The label is common shorthand for an independent contractor, and the distinction matters for every piece of paperwork below.

Collect Form W-9 Before the First Payment

Form W-9 is where the contractor gives you the information you’ll need to report their income to the IRS: legal name, business name if different, federal tax classification, and taxpayer identification number.² The form asks the contractor to check a box for their classification (individual or sole proprietor, C corporation, S corporation, partnership, trust or estate, or LLC) and to provide either a Social Security Number or an Employer Identification Number.³

The contractor signs Part II under penalty of perjury, certifying that the TIN is correct and that they aren’t subject to backup withholding. If a contractor refuses to complete a W-9 or won’t certify, you may be required to withhold 24 percent of every payment and remit it to the IRS as backup withholding.³

Get the W-9 in hand before the first check goes out. Chasing contractors for tax paperwork after the job ends is one of those avoidable problems that shows up every January. Keep each W-9 on file for at least four years after the date the related tax becomes due or is paid, whichever is later.⁴

Put the Independent Contractor Agreement in Writing

A written contract isn’t just good practice. It’s one of the factors the IRS weighs when deciding whether a worker is genuinely a contractor or a misclassified employee, and it’s the document that spells out what you and the contractor actually agreed to.

The agreement should state clearly that the worker is an independent contractor, not an employee, and that your business will not withhold taxes or provide benefits such as health insurance, retirement contributions, or paid leave. Beyond that, it should cover:

Scope of work: what the contractor will deliver and by when, described specifically enough to prevent disputes but without dictating hour-by-hour methods, which can look like employment.
Payment terms: the agreed rate, whether flat fee or hourly, and the payment schedule.
Intellectual property: who owns the work product once it’s delivered.
Confidentiality: how the contractor handles sensitive information.
Termination: how either party can end the relationship and what notice is required.

Some businesses also require contractors to carry general liability insurance and to provide a certificate of insurance before work starts. Whether that’s worth insisting on depends on the work, but for anything physical or on-site, it’s a reasonable ask.

Track Every Invoice and Payment

Keep a dedicated file for each contractor with every invoice, payment date, dollar amount, and payment method. Without that, you can’t reliably tell at year’s end who crossed the reporting threshold or whether the numbers on your 1099-NEC match what actually went out.

Payment method matters more than most businesses realize. Payments made by credit card, debit card, or through a third-party payment app like PayPal or Venmo are reported by the payment processor on Form 1099-K, not by you on Form 1099-NEC.⁵ The 1099-K threshold is $20,000 and 200 transactions per payee.⁶ If you pay a contractor entirely by card or app, you likely don’t file a 1099-NEC for them at all. Tag each payment method in your records so you know at year’s end which contractors need a 1099-NEC from you and which are covered by their processor.

File Form 1099-NEC by January 31

Form 1099-NEC reports nonemployee compensation paid during the calendar year.⁷ For tax year 2026, you must file one for every contractor who received $2,000 or more in nonemployee compensation.¹ The threshold sat at $600 for decades, so update your internal cutoffs if you haven’t already. The $2,000 figure will be adjusted for inflation starting in 2027.

The deadline is January 31 for both the copy filed with the IRS and the copy sent to the contractor, whether you file on paper or electronically.⁸ Different copies go to different places. Copy A goes to the IRS. Copy B goes to the contractor for their tax return. Copy 1 goes to the state tax department if your state requires it. Copy C stays in your files.

Electronic Filing Threshold

If your business files 10 or more information returns of any type in a calendar year, you’re required to file electronically.¹ The count aggregates across form types, so four Forms 1098 plus six Forms 1099 hits ten and triggers the e-file rule. The IRS is transitioning from its legacy FIRE system to a newer portal called IRIS, with FIRE targeted for retirement after filing season 2027.⁹

Fixing an Error After Filing

If you find a mistake on a 1099-NEC you already filed, correct it promptly. Check the “CORRECTED” box on a new form, enter the correct information, and submit it with a new Form 1096. Corrections to an e-filed return must also be e-filed.¹⁰

A wrong TIN or name takes two filings: one return that zeroes out the incorrect version and a second with the correct information filed as an original. Note in the bottom margin of Form 1096 whether you’re correcting a TIN, a name, or a return.¹⁰ Getting corrections in by August 1 can meaningfully reduce penalties, so don’t sit on known errors.

State Filing

Many states also want a copy of your 1099-NEC. The IRS runs a Combined Federal/State Filing program that automatically forwards your electronically filed 1099-NEC data to participating states, which can spare you a second filing.¹¹ Some participating states still require separate notification that you’re using the program, and the IRS acts only as a forwarding agent. Check the rules in each state where your contractors work.

What It Costs to Skip the Paperwork

Filing penalties for late or incorrect information returns are tiered under IRC Section 6721. The per-return penalty is lowest if you correct within 30 days of the deadline, higher if corrected by August 1, and highest after that. Annual caps apply, with lower caps for businesses with gross receipts under $5 million.¹² The dollar amounts in the statute are adjusted for inflation each year.

Missing paperwork also weakens your position if the IRS ever questions whether your “contractor” was really an employee. When the IRS reclassifies a worker, your business can owe back employment taxes, including the employer share of Social Security and Medicare plus income tax withholding you should have collected. Independent contractors normally pay a combined 15.3 percent self-employment tax themselves, covering both the employer and employee portions of Social Security (12.4 percent) and Medicare (2.9 percent).¹³ On reclassification, your business picks up the employer half plus penalties and interest.

A limited safe harbor exists under Section 530 of the Revenue Act of 1978. If you filed all required 1099s consistently, never treated a similar worker as an employee, and had a reasonable basis for treating the worker as a contractor, the IRS may relieve you of the back employment taxes.¹⁴ That relief hinges on having filed those 1099s on time. Skipping the paperwork doesn’t just trigger filing penalties. It can take your best defense off the table if the classification itself is ever challenged.
