How To Send a 1099 Form to Someone

The Basic Steps for Sending a 1099

You send a 1099 by filing it with the IRS and mailing a copy to the person who earned the income. The IRS requires you to file Copy A (the official red-ink version) with the Social Security Administration by January 31 of the year after payment. At the same time, you mail Copy B to the recipient at their address on file. You keep Copy C for your own records.

The exact method depends on how many 1099s you're sending. If you're sending just one or two, you can file by mail or use IRS e-file. If you're sending more than 250 forms in a year, the IRS requires you to file electronically through the Filing Information Returns Electronically (FIRE) system or through a third-party software provider.

The important date is firm: January 31. If you miss it, you face penalties starting at $50 per form, though the IRS may waive penalties if you file within 30 days of the important date and show reasonable cause.

Key Takeaways

• You must file Copy A with the IRS and mail Copy B to the recipient by January 31 of the following year.
• Forms with 250 or more 1099s must be filed electronically through FIRE or approved software; fewer than 250 can be mailed.
• The recipient needs their correct name, address, and tax ID (usually Social Security number) on the form.
• You keep Copy C for your records and should retain documentation of all payments for at least three years.

Getting the Recipient's Information Right

Before you send anything, you need the recipient's full legal name, current mailing address, and tax identification number. For most people, that's their Social Security number. If they're a business, it's their Employer Identification Number (EIN). If the information is wrong, the IRS will reject the filing or the recipient won't be able to match it to their tax return.

Ask the recipient to fill out a Form W-9 if you don't already have their information. This form gives you their name, address, and tax ID in the format the IRS expects. Keep the W-9 on file for at least three years. If someone refuses to provide a W-9 and you still pay them, you're required to withhold 24 percent of the payment for backup withholding and send that to the IRS instead.

If the recipient's address changes after you've issued the form, you don't need to reissue it. The IRS uses the address on file with them, not the one on your 1099.

Choosing Between Mailing and Electronic Filing

If you have fewer than 250 forms to file, you can mail Copy A to the Social Security Administration and mail Copy B to each recipient. You'll need to include a Form 1096 (a cover sheet) with your mailed Copy A forms. The SSA address for mailing is on the Form 1096 itself and changes by state.

If you have 250 or more forms, you must file electronically. You can use the IRS FIRE system directly, or you can use approved third-party software like tax preparation programs or payroll services. These services handle the formatting and transmission for you. The cost varies—some charge per form, others charge a flat fee. Many payroll providers include 1099 filing as part of their service.

Electronic filing is faster and has fewer rejection errors than mailing. If you're mailing, allow extra time for postal delays and SSA processing.

What Information Goes on the Form

A 1099 requires specific boxes to be filled depending on the type of income. For a 1099-NEC (nonemployee compensation), you report the total amount paid in Box 1. For a 1099-MISC (miscellaneous income), different types of payment go in different boxes—royalties in Box 2, rent in Box 1, and so on. If you withheld taxes, that amount goes in Box 4.

You also need your own name, address, and tax ID on the form. Double-check that all dollar amounts match your records and that you're using the correct form type for the income you paid. Using the wrong form type can delay the recipient's tax return or trigger an IRS notice.

If you made a mistake after sending the form, you can file a corrected 1099 (marked "CORRECTED" at the top) with the same important date as the original. Send the corrected version to both the IRS and the recipient.

Mailing Copies to Recipients

You must mail Copy B to the recipient by January 31. Use their address from the W-9 or the most recent address you have on file. The form can be mailed in a regular envelope—there's no special requirement. Many people send them in January along with a cover letter explaining what the form is and how to use it on their tax return.

Keep a record of when you mailed the forms. If a recipient claims they never received theirs, you'll have proof you sent it. Some businesses mail 1099s by certified mail for this reason, though it's not required.

If a recipient's address is unknown or they've moved and you can't locate them, you still must file Copy A with the IRS by the important date. Make a reasonable effort to find their current address, but don't delay your filing waiting for it.

Filing Copy A With the IRS

Copy A goes to the Social Security Administration, which processes it for the IRS. If you're mailing, you'll include a Form 1096 cover sheet listing all the forms in your batch. The SSA address varies by state—check the Form 1096 instructions for the correct address for your location.

If you're filing electronically through FIRE, you'll upload the forms directly through the IRS website. You'll need an IRS e-services account and a PIN. The system validates your forms before you submit them and tells you when ready if there are errors.

Once the IRS receives and processes your filing, you won't hear anything unless there's a problem. If there is, they'll contact you by mail. Keep copies of your filing confirmation (if electronic) or your mailing receipt for your records.

Common Mistakes to Avoid

The most common error is using the wrong form type. A 1099-NEC is for independent contractors and self-employed people. A 1099-MISC is for other types of income like rent, royalties, or prizes. Using the wrong one delays processing and can confuse the recipient's tax filing.

Another frequent mistake is mismatching names or tax IDs. If the name on the 1099 doesn't match the name the recipient uses on their tax return, the IRS computer system won't match them up, and the recipient may get a notice asking them to explain the discrepancy.

Missing the January 31 important date is also common, especially for people filing by mail. The important date is strict, and penalties start when ready. If you know you'll miss it, file what you can electronically by the important date and follow up with corrections or late filings as soon as possible.

Frequently Asked Questions

Do I have to send a 1099 to someone I paid less than $600?

It depends on the type of income. For most 1099-NEC payments, the threshold is $600 in a calendar year. For 1099-MISC, the threshold varies by category—rent is $600, but royalties are $10. Check the instructions for the specific form type you're using.

What if the recipient says they never got their copy?

You can mail a duplicate Copy B to them at any time. There's no important date for sending duplicates to the recipient, though the IRS important date for filing Copy A is still January 31. Keep a note that you sent a duplicate.

Can I send a 1099 electronically to the recipient instead of by mail?

The IRS does not allow electronic delivery of Copy B to the recipient. You must mail it. However, some states and some recipients may have different rules, so check your state's tax authority if you're unsure.

What happens if I file the 1099 late?

The IRS charges a penalty of $50 per form if you file after January 31, though the penalty may be reduced if you file within 30 days and show reasonable cause. Penalties can add up quickly if you're filing many forms late.

Do I need to keep the W-9 after I file the 1099?

Yes. Keep the W-9 and all payment records for at least three years in case the IRS audits you or the recipient disputes the amount reported.
