1099 vs W-9: A Plain-English Guide for Small Business Owners

Blog Summary / Key Takeaways

• The W-9 is filled out by the person being paid, it gives you their tax information before you pay them
• The 1099 is filed by the business doing the paying, it reports to the IRS what you paid after the year ends
• Think of it this way: W-9 comes first, 1099 comes after
• You need a 1099 for any non-employee you pay $600 or more in a calendar year
• Getting these backwards or skipping the W-9 creates IRS problems every January
• Small business owners should collect W-9s at contractor onboarding, every time, without exception

If you have ever hired a freelancer, contractor, or any service provider who is not on payroll, you have probably heard the words W-9 and 1099 in the same conversation.

Most small business owners know they need both. Not as many know which one does what, who is responsible for each, or what happens when one gets skipped.

This guide explains both forms in plain English no jargon, no unnecessary complexity.

The One-Sentence Explanation

The W-9 is the form your contractor gives you. The 1099 is the form you send to the IRS and your contractor after you have paid them.

That is the whole thing. The rest of this guide is context.

What Is a W-9 Form?

A W-9 is a one-page IRS form called Request for Taxpayer Identification Number and Certification. It is filled out by the person or business you are paying not by you.

When you hire a freelancer or contractor, you send them a blank W-9. They fill it in with their legal name, business name if they have one, address, tax classification, and most importantly their Taxpayer Identification Number- either a Social Security Number or an EIN.

They give the completed W-9 back to you. You keep it on file. You do not send it to the IRS.

The W-9 is a form your contractor gives you so you have what you need to report their income at year end.

What Is a 1099 Form?

A 1099 is an IRS information return that reports income paid to someone who is not your employee. The most common version for small businesses is the 1099-NEC, which stands for Non-Employee Compensation.

You, the business owner, prepare the 1099 at the end of the year using the information from the W-9. It shows how much you paid that contractor during the year. You send one copy to the contractor and file another copy with the IRS by January 31.

The contractor uses their copy to report income on their tax return. The IRS uses their copy to verify that the contractor reported it.

1099 vs W-9: Which Comes First?

The W-9 always comes first. You cannot file the 1099 correctly without the information on the W-9.

Do You Always Need a 1099?

No, the 1099-NEC is required only when you pay a contractor $600 or more in a calendar year. But the W-9 should be collected regardless of how much you expect to pay, because:

• Payments can add up across a year faster than expected

• It is much harder to collect a W-9 after the work is done than before

• You need the W-9 to determine whether the 1099 exemption applies (for corporations, for example)

Who Does NOT Need a 1099?

What Happens If You Skip the W-9?

If you pay a contractor without a W-9 on file and they hit the $600 threshold, you have two problems.

First, you cannot file the 1099 accurately because you do not have their correct name and TIN. If you file with incorrect information, the IRS sends a CP2100 notice and may require backup withholding on all future payments at 24%.

Second, if the contractor refuses to provide a W-9 even when asked after the fact, you are required to withhold 24% from any future payments until they do.

The prevention is simple: no W-9, no payment. Make it a rule and stick to it.

Real Scenario: A Restaurant Owner Who Paid Contractors in Cash

A small restaurant owner in Phoenix hired a freelance graphic designer to create a new menu and website. He paid her $1,200 over three months - $400 cash each time. He did not collect a W-9 because he was paying cash and thought that meant no paperwork.

In January, his accountant told him he needed to file a 1099-NEC for the designer. He did not have her SSN or EIN. She had moved to a different city.

After two weeks of back-and-forth emails, she provided the W-9 information reluctantly. The 1099 was filed late. The IRS assessed a $60 penalty.

The accountant added a contractor onboarding step: collect the W-9 before approving the first payment, regardless of payment method.

FAQs

What is the difference between a 1099 and a W-9?

‍A W-9 is filled out by the contractor before work begins and gives you their tax identification information. A 1099 is prepared by you after the year ends and reports to the IRS what you paid that contractor. W-9 first, 1099 after.

Does my contractor fill out the W-9 or the 1099?

‍Your contractor fills out the W-9. You fill out the 1099. The contractor receives a copy of the 1099 from you but does not prepare it.

Do I need a W-9 from every contractor?

Yes, collect a W-9 from every contractor at the start of the relationship, before the first payment. You will need it if their total payments hit $600, and it is much harder to collect after the work is done.

What is the 1099 filing deadline?

January 31 of the year following payment. For contractors paid in 2025, the 1099-NEC is due January 31, 2026.

Can I pay a contractor without a W-9?

You can, but you should not. Without a W-9, you cannot file the 1099 accurately. If the contractor refuses to provide one, you are required to withhold 24% of payments as backup withholding.

Do I need a 1099 for a contractor I paid less than $600?

No, the filing threshold is $600 total per calendar year. But collect the W-9 anyway. Payments can add up and the threshold applies to cumulative annual payments, not individual transactions.

What is a 1099-NEC?

1099-NEC stands for Non-Employee Compensation. It is the specific 1099 form used to report payments to freelancers, independent contractors, and other non-employees. It replaced Box 7 of the 1099-MISC for this purpose starting in tax year 2020.

Conclusion

The 1099 vs W-9 confusion is one of the most common small business tax questions and one of the most avoidable sources of January stress for accounting firms.

The answer is straightforward: W-9 from the contractor before you pay them, 1099 from you to the IRS and the contractor after the year ends. In that order, every time.
