Does ADP File 1099s With the IRS for You?

Yes, ADP can file 1099s with the IRS on your behalf. It’s offered as part of ADP’s year-end tax compliance services, usually as an add-on to standard payroll rather than a default feature. ADP prepares the forms, prints and mails recipient copies, transmits the electronic file to the IRS, and handles most state submissions. What it will not do is verify your data. Every name, taxpayer identification number, payment total, and classification decision comes from you, and the IRS penalties for getting any of that wrong land on your business.

What ADP Actually Files

ADP’s 1099 service covers the mechanical work of year-end reporting: pulling contractor payment data from your payroll records, generating the forms, mailing recipient copies, and electronically transmitting the federal return.¹ It also handles state agency filings, either through direct submission or through the IRS Combined Federal/State Filing Program, which forwards your federal 1099 data to participating state tax agencies.²

To file on your behalf, ADP operates as an authorized reporting agent under IRS rules. Most businesses complete Form 8655 (Reporting Agent Authorization) to give ADP the authority to sign and file returns, make tax deposits, and receive related IRS notices.³

Before ADP transmits anything, you review and digitally approve a final proof of the 1099 data through the ADP portal. That sign-off is the moment responsibility for accuracy locks in on your side.

What You Still Have to Do

ADP files what you give it. It does not independently verify contractor names, addresses, or TINs, it does not decide whether a worker should be classified as an employee or a contractor, and it does not chase down missing W-9s.

Before you pay any contractor, get a completed Form W-9 on file. The W-9 gives you the contractor’s legal name, business name, tax classification, and TIN. If the name-and-TIN combination doesn’t match IRS records, you’ll face mismatch penalties later.⁴ The W-9 also tells you whether the payee is a corporation, and most corporate payments are exempt from 1099 reporting. The main exceptions are payments for medical and health care services and gross proceeds paid to attorneys, which must be reported even when the recipient is a corporation.⁵

The reporting threshold is $600 or more paid to a non-employee in a calendar year. Payments for services go on Form 1099-NEC. Other categories such as rent, prizes, and certain medical payments go on Form 1099-MISC.⁵

Payments you make outside the ADP platform, through direct bank transfers or checks written from a separate account, have to be entered or imported before ADP’s cutoff. If a payment slips through and you underreport a contractor’s compensation, the mismatch flag hits your business.

Exclude Card and Payment-App Transactions

One of the most common 1099 errors is double-counting payments made by credit card or through a third-party network like PayPal, Venmo, or Stripe. Those payments are reported on Form 1099-K by the payment processor, not on Form 1099-NEC by you.⁵ Payment processors are required to file a 1099-K when a payee receives more than $20,000 across more than 200 transactions in a calendar year.⁶ Whether or not a 1099-K actually gets issued for a given contractor, exclude those transactions from what you send ADP for the 1099-NEC.

If you paid a contractor $8,000 by check and $4,000 by credit card, only the $8,000 goes on the 1099-NEC. Getting this wrong inflates the contractor’s reported income and creates the exact kind of mismatch the IRS follows up on.

Reimbursed expenses, when properly documented and separated from service fees, should also be excluded from the reportable total.

ADP’s Deadline Is Earlier Than the IRS Deadline

The IRS deadline for both furnishing Form 1099-NEC to the contractor and filing it with the IRS is January 31. There is no automatic extension.⁵

ADP sets its own data submission cutoffs weeks before that, often in early to mid-January, so it has time to process forms across all clients. Treat ADP’s internal date as the real deadline. By the time January 31 arrives, your window to submit or correct data through ADP may already be closed.

Businesses filing 10 or more information returns in a calendar year, counting all types including W-2s, must file electronically.⁷ Most ADP clients easily cross that threshold.

Who Pays the Penalty When Something Goes Wrong

The IRS penalizes the business for each 1099 that is filed late, filed with wrong information, or not filed at all. For 2026, the per-return penalties are:⁸

Corrected within 30 days: $60 per return
Corrected by August 1: $130 per return
After August 1 or never filed: $340 per return
Intentional disregard: $680 per return, with no annual cap

Annual caps limit total exposure for non-intentional failures, and those caps are lower for small businesses with average annual gross receipts of $5 million or less.⁹

The division of labor with ADP matters here. If ADP files late because you missed its internal cutoff, the IRS penalizes your business. If ADP files on time but with a wrong TIN because you entered it incorrectly, the penalty still lands on you. ADP is the messenger.

Backup Withholding After a TIN Mismatch

When the IRS finds that a name-and-TIN combination on a filed 1099 doesn’t match its records, it sends a CP2100 or CP2100A notice to the payer. These notices list every payee with a missing, incorrect, or unissued TIN, and the response obligations fall on the business, not ADP.¹⁰

For a completely missing or obviously wrong TIN, you must begin backup withholding immediately at 24% of all future payments to that contractor.⁴ For a TIN that simply doesn’t match, you send the contractor a “B notice” requesting the correct information. If the contractor doesn’t respond, backup withholding must start no later than 30 business days after you received the CP2100 notice.¹⁰

Backup withholding is not optional. Failing to withhold when required makes the business liable for the uncollected tax.

Fixing Errors After ADP Has Filed

If you discover an error on a 1099 that ADP already submitted, you’ll need to file a corrected return. ADP can file corrections on your behalf, but the window through ADP’s platform may narrow after the initial filing season. The sooner you catch it, the smaller the penalty: correcting within 30 days of the filing deadline drops the per-return penalty from $340 to $60.⁸

You can also request penalty relief by showing “reasonable cause.” The IRS evaluates these requests case by case, weighing whether you acted responsibly before and after the failure. First-time filers, businesses with a clean compliance history, and companies that fixed the problem quickly tend to fare better.¹¹ Requests go through the number on your IRS penalty notice or in writing on Form 843.

State Filings Through ADP

Most states require a 1099 filing at the state level as well. ADP handles this either through direct submission to the state or through the IRS Combined Federal/State Filing Program, which forwards your federal 1099 data to participating states automatically.²

Not every state participates in CF/SF, and the IRS acts only as a forwarding agent with no responsibility for state compliance. Confirm with ADP whether your state is covered through the program or needs a direct filing. State penalties are separate from federal ones and stack on top when both filings are missed.
