How to Fill Out Form W-9: A Step-by-Step Guide for Business Owners

If your business hires freelancers, independent contractors, or vendors who aren’t on payroll, you need to file Form W-9. Filing this ensures your business stays compliant with IRS rules when preparing year-end tax reports like Form 1099. In this guide, we’ll walk you through how to file for a W-9 step by step and show you the safest ways to submit it. Getting it right from the start avoids confusion, errors, and tax season delays.

Steps to file form W-9

Step 1: Get the Official W-9 Form

Always download the W-9 form from the IRS website. Avoid third-party sources to ensure the version is current. The form itself is just one page, followed by a few pages of instructions. Print a few copies or fill it out digitally, depending on your process.

Step 2: Fill in the Payee’s Legal Name (Line 1)

This should match exactly what appears on their federal tax return. For individuals, this will be their full legal name. If the payee is a single-member LLC or sole proprietor, they should still enter their legal name here.

Step 3: Add Business Name or DBA (Line 2)

If the person or business operates under a different name (like a "Doing Business As" name), it should be entered on Line 2. This is optional for individuals without a separate business name.

Step 4: Choose the Correct Federal Tax Classification (Line 3)

This part determines how the IRS views the payee for tax purposes. Only one box should be checked:

Individual or Sole Proprietor – for self-employed individuals or single-member LLCs
C Corporation – if the business is taxed as a standard corporation
S Corporation – if the business has elected pass-through taxation
Partnership – for businesses with multiple owners that are not corporations
Trust or Estate – only if you're filling the form on behalf of a trust or estate
Limited Liability Company (LLC) – if applicable, enter the tax classification code:
C for C Corp
S for S Corp
P for Partnership

If the entity is a single-member LLC, the "Individual/sole proprietor" box is typically checked.

Step 5: Complete the Exemption Codes (Line 4, if needed)

Most individuals and small businesses can leave this blank. This line is for entities that are exempt from backup withholding or FATCA reporting. If someone is unsure whether this applies, they should check with their tax advisor.

Step 6: Enter the Address (Lines 5 & 6)

This is where the IRS tax documents will be sent. Make sure the address is complete and accurate:

Line 5 – Street address
Line 6 – City, state, and ZIP code

Step 7: Fill in the Taxpayer Identification Number (TIN) – Part I

This is one of the most important parts of the form. The person must provide either:

Social Security Number (SSN) – if they’re an individual or sole proprietor
Employer Identification Number (EIN) – if they operate under a registered business

Choose either SSN or EIN based on your classification. Do not enter both.

Step 8: Sign and Date – Part II

A handwritten or digital signature confirms that:

The information provided is accurate
The signer is not subject to backup withholding.
They are a U.S. person (citizen or resident)

Without a signature, the form is invalid and should not be accepted.

How to Submit a W-9 Form Securely

Your W-9 includes sensitive information like your SSN or EIN. To protect it, choose a secure delivery method:

Digital Options

Secure Portals: If the business has an encrypted upload system, use it.
Password-Protected Files: Save the W-9 as a PDF with a password, then share the password separately via phone or text.
Digital Signature Services: Platforms like DocuSign and Adobe Sign add an extra layer of security and validation.
Encrypted Email: Only use email services with strong encryption—never send an unprotected form.

Physical Options

Hand Delivery: Still one of the most secure options when possible.
Certified Mail: USPS tracking helps confirm safe delivery.

Avoid sending W-9s via public Wi-Fi, unprotected email, or text. Also, don’t leave hard copies in shared spaces like printers or fax trays. Pro tip: After sending the form, ask the recipient to confirm receipt and clarify how they’ll store the document.

How Businesses Use the W-9

Once you collect the completed form, don’t send it to the IRS. Instead, keep it on file for at least four years. The information on the W-9 is used to prepare:

Form 1099-NEC for contractor payments
Form 1099-MISC for miscellaneous payments
Form 1099-DIV for dividends
Form 1099-INT for interest

Having the right information early helps ensure accurate year-end tax filings.
