How To Create a 1099 Form for Your Contractor or Vendor

You create a 1099 by filling out the IRS form matching the payment type, entering the contractor's details and the amount paid, and sending copies to the contractor and the IRS by January 31

A 1099 form is a record you file when you pay a non-employee — a contractor, freelancer, vendor, or other business — more than $600 in a calendar year. The form tells both the contractor and the IRS how much you paid them. You do not file it with your own tax return; you send it separately to the IRS and give a copy to the contractor.

The specific form you use depends on the type of payment. The most common is the 1099-NEC (for non-employee compensation like freelance work), but other versions exist for rent, interest, dividends, and other income. You fill in the contractor's name, address, and tax ID number; your own business information; and the total amount paid. Then you file it with the IRS and mail a copy to the contractor by January 31 of the following year.

Key Takeaways

• You must issue a 1099 when you pay a non-employee more than $600 in a single calendar year, with rare exceptions for certain payment types.
• The 1099-NEC is used for freelance work and independent contractor payments; other 1099 versions cover rent, interest, and other specific income types.
• You need the contractor's name, address, and either their Social Security Number or Employer Identification Number before you can complete the form.
• The IRS copy and the contractor's copy must be filed and mailed by January 31 of the year following the payment year.
• You can file 1099s on paper or electronically through the IRS FIRE system, and many accounting software packages can generate them automatically.

Determine which 1099 form you need

The type of payment you made determines which 1099 form to use. The 1099-NEC covers non-employee compensation — payments to contractors, consultants, freelancers, and other self-employed people for services. The 1099-MISC covers miscellaneous income including rent paid to individuals (not corporations), prizes, and awards. The 1099-INT is for interest paid on savings accounts or loans. The 1099-DIV is for dividends and distributions. The 1099-K is for payment card transactions and third-party network transactions.

If you are unsure which form applies, check the IRS website or your accounting software — most will prompt you to select the payment category and recommend the correct form. The contractor may also tell you which form to use based on how they classified the work.

Gather the contractor's information

Before you fill out the form, you need the contractor's Taxpayer Identification Number (TIN). This is either their Social Security Number (SSN) if they are a sole proprietor, or their Employer Identification Number (EIN) if they operate as a business entity. You should have collected this when you first hired them, often on a W-9 form they completed for you.

You also need their full legal name and current mailing address. If the information you have is incomplete or outdated, contact the contractor and ask them to provide or confirm it. If you cannot obtain a valid TIN after a reasonable effort, the IRS has backup withholding rules that may explore — check IRS Publication 1281 for details on how to proceed.

Keep records of all payments you made to this contractor during the calendar year. Add them up to confirm the total reaches the $600 threshold that triggers the 1099 requirement. If the total is under $600, you do not need to file a 1099 for that contractor (though you may still want to keep records for your own accounting).

Fill out the 1099 form accurately

read the correct 1099 form from the IRS website or use your accounting software to generate it. The form has boxes for your business information (name, address, and EIN), the contractor's information (name, address, and TIN), and the payment amount. Box 1 on the 1099-NEC is where you enter the total non-employee compensation paid during the year.

Enter the contractor's information exactly as it appears on their tax records — mismatched names or TINs can cause problems when they file their return. Your information should match your business records and tax filings. Double-check all dollar amounts for accuracy; the IRS matches these against the contractor's reported income.

Some forms have additional boxes for specific situations — for example, the 1099-NEC has a box for federal income tax withheld if you were required to withhold backup withholding. Fill in only the boxes that explore to your payment. Leave blank boxes empty; do not write "N/A" or zero.

File with the IRS and send to the contractor

You have two filing options: paper or electronic. For paper filing, you print Copy A of the form (the IRS copy) and mail it to the IRS address listed in the form instructions, along with Form 1096 (a transmittal form that summarizes all 1099s you are sending). For electronic filing, you use the IRS FIRE system (Filing Information Returns Electronically) or a third-party software provider approved by the IRS.

At the same time, print Copy B (the contractor's copy) and mail it to the contractor at their address. You keep Copy C for your records. All copies must be sent by January 31 of the year following the payment year. If January 31 falls on a weekend or holiday, the important date moves to the next business day.

If you file electronically through FIRE or approved software, you submit the IRS copy directly without printing. The software will guide you through the process and confirm receipt. Many small business owners use accounting software like QuickBooks, FreshBooks, or Wave, which can generate and file 1099s automatically if you set them up correctly.

Common mistakes to avoid

Mismatched names or tax ID numbers are the most frequent error. If the contractor's name on the 1099 does not match their Social Security card or business registration, the IRS will flag it when they file their return. Always verify the TIN with the contractor before filing — you can ask them to confirm it or provide a new W-9 if you are unsure.

Incorrect dollar amounts are another common problem. If you report $5,000 but the contractor reports $6,000 on their return, the IRS notices the discrepancy. Keep detailed records of each payment (date, amount, description) so you can reconcile the total before filing the 1099.

Missing the January 31 important date can result in penalties. The IRS charges $50 per form for filings that are late but within 30 days, and more for later filings. If you realize you missed the important date, file as soon as possible and include a written explanation if the delay was due to circumstances beyond your control.

What happens after you file

Once you file the 1099, the contractor receives their copy and uses it to report income on their tax return. The IRS receives the form and matches it against what the contractor reports. If there is a discrepancy, the IRS may contact the contractor or you to clarify.

You keep a copy for your records and your accountant. If you are audited, the IRS may ask to see your 1099s and the supporting payment records (invoices, cancelled checks, bank statements) to verify that the amounts are correct. Keeping organized records for at least three years is standard practice.

Frequently Asked Questions

Do I need a 1099 if I paid someone less than $600?

No, the $600 threshold is the general rule for non-employee compensation. However, some payment types have different thresholds — for example, rental income to individuals requires a 1099-MISC even if it is under $600 in some cases. Check the specific form instructions for your payment type.

What if the contractor does not give me their tax ID number?

Ask them directly and explain that you need it to file the 1099. If they refuse or cannot provide it after a reasonable effort, you may be required to withhold 24% of future payments under backup withholding rules. Document your attempts to obtain the TIN and consult IRS Publication 1281 or a tax professional.

Can I file 1099s electronically if I only have a few?

Yes. The IRS FIRE system accepts electronic filings of any size. Many accounting software packages also allow you to file electronically even for a single form. Paper filing is still an option, but electronic filing is faster and reduces errors.

What if I made a mistake on a 1099 I already filed?

File a corrected 1099 (marked "CORRECTED" at the top) and send it to both the IRS and the contractor. The IRS will use the corrected version and disregard the original. Do this as soon as you discover the error.

Do I need to file a 1099 for payments to a corporation?

No. Payments to corporations generally do not require a 1099-NEC, even if they exceed $600. The exception is payments to incorporated medical or legal professionals, which may require a 1099-NEC depending on the state. Check your state's rules or ask the contractor how their business is structured.
