Request W9 Forms from vendors

Key Takeaways

  • Collect Form W-9 when a vendor is onboarded so there is time to check the information and fix any issues before filing season.
  • Form W-9 gives the payer the vendor’s legal name, TIN, tax classification, exemption details, and certifications needed for 1099 reporting.
  • The vendor’s tax classification and exemption details help determine whether certain payments need to be reported on a Form 1099.
  • The TIN and certifications on Form W-9 also help the business determine when backup withholding may apply.

Hiring a contractor or adding a new vendor creates more than an accounts payable record. If the vendor subsequently receives a reportable payment, your business will need to know the vendor’s correct legal name, Taxpayer Identification Number and federal tax classification to prepare an information return.

That’s why companies routinely request a W-9 from vendors when they join a company instead of waiting until January. Form W-9 helps provide information about the payee, the federal tax classification of the payee, and which TIN should be used for reporting. It also helps in making backup withholding decisions when necessary.

Why Should Businesses Request Form W-9 From Vendors?

The main purpose of a W-9 for vendors is to give the payer reliable tax information before a reporting obligation arises.

Verify the vendor’s name and TIN

A Form W-9 includes the taxpayer’s name and TIN that might be used on a Form 1099 or other information return.

The wrong name/TIN combination can result in IRS mismatch notices and further vendor follow-up. The advantage of collecting the information directly from a signed W-9 is that a business will have a documented source from which to obtain the information to use in their vendor records.

Determine the vendor’s federal tax classification

A completed W-9 can identify the payee as an individual or sole proprietor, C corporation, S corporation, partnership, trust or estate, or an LLC with the appropriate federal classification.

This is important because it can determine whether a payment is reportable or not, based on federal tax classification. For example, an LLC label alone does not indicate to the payer if the entity is taxed as a corporation, partnership or disregarded entity.

Document possible reporting exemptions

Some payments, including certain legal and medical payments, may still need to be reported. However, many other payments to corporations are generally exempt from Form 1099-NEC and Form 1099-MISC reporting.

The W-9 provides tax classification, exemption code, and TIN information that should be used to help determine whether or not the payee is exempt.

Support backup-withholding decisions

The vendor’s TIN and certifications also help determine whether W-9 backup withholding rules apply.

Qualifying reportable payments may be subject to the 24% federal backup withholding rate if a payee fails to furnish a TIN or an IRS notice requires backup withholding due to a TIN issue.

When and From Whom Should a Business Request Form W-9?

Knowing when to request a W-9 can help avoid year-end filing delays.

Ask for it at the time of vendor onboarding

As a general rule, businesses should seek tax information prior to making potentially reportable payments.

For example, you hire an independent consultant in February, but only request a W-9 in January next year. When this happens, a consultant might be hard to find by the time you need to fill out a 1099.

It is collected at onboarding, which allows the accounts payable and tax teams time to validate the information.

Request updated information when something changes

A new W-9 may be appropriate when the vendor reports a change involving its:

  • Legal name
  • TIN
  • Federal tax classification
  • Exemption status
  • Information that affects reporting or withholding

If the information in the W-9 is the same for a business, they do not need a new W-9 every calendar year.

Use Form W-9 for U.S. persons

Form W-9 is generally used to obtain a TIN and certifications from a U.S. person, including a U.S. resident alien.

Instead, a foreign vendor generally supplies the appropriate Form W-8.

What Information Should Businesses Review on Form W-9?

Review the entries while the vendor is still available to correct mistakes.

W-9 Information Why It Matters
Legal name The taxpayer whom the TIN belongs to
Business/disregarded entity name Connects an operating name with the tax owner
Federal tax classification Helps determine reporting treatment
Exemption codes Documents exemptions for reporting or withholding
Address Helps to maintain records for both payers and recipients
SSN, ITIN, or EIN Provides the TIN used for reporting
Certification Confirms applicable TIN and backup-withholding statements

For a disregarded entity, the name and TIN rules require the tax owner’s information instead of just the operating LLC name. Checking the form will ensure that the payer doesn’t transfer incorrect entity information to a Form 1099.

Keep the W-9 in your records

The vendor gives Form W-9 to the requesting business. Typically, the payer retains the form and does not submit the W-9 to the IRS.

How Does Form W-9 Support 1099 Reporting?

While W-9 and 1099 reporting are connected, a W-9 does not necessarily mean that the vendor will receive a Form 1099.

The business still needs to determine:

  1. What the payment was for.
  2. If that category of payment is subject to reporting.
  3. Whether the relevant reporting threshold was met or not.
  4. If the payee’s classification results in an exemption.
  5. If the method of payment alters the reporting of the transaction.

After answering those questions, the W-9 includes information the payer should use to prepare an appropriate Form 1099-NEC, Form 1099-MISC, or other information return.

This is another reason why it may be advantageous to collect a W-9 from a corporation even if many of the payments were not reportable. The form includes the payee’s federal tax classification, which helps support the reporting decision.

What Should a Business Do if a Vendor Does Not Provide a Valid W-9?

Do not wait until filing season just to resolve missing information.

Request the missing or corrected details

If the vendor fails to include a necessary TIN, or leaves out any information or offers information that seems inconsistent, contact the vendor and ask for a corrected form.

Apply backup withholding when required

When the rules apply, backup withholding is typically 24%. Situations include when the payee has not provided the required TIN or the IRS informs the payer of a name/TIN issue and requires the payer to take action.

A business should follow the applicable IRS backup-withholding and B-notice procedures rather than inserting a guessed TIN just to complete a Form 1099.

Common Form W-9 Scenarios for Businesses

Business Scenario What to Do Why It Matters
Business hires a U.S. independent contractor Have the contractor complete Form W-9 during onboarding The name and TIN are ready if Form 1099-NEC is required
Business begins paying rent to a U.S. property owner Collect Form W-9 from the property owner or landlord The information is available if the rent must be reported on Form 1099-MISC
Vendor identifies itself as a corporation Keep the vendor’s W-9 and review the type of payment being made Some payments to corporations are exempt from 1099 reporting, while others are still reportable
Contractor does not provide a valid TIN Follow up with the contractor for the missing or corrected TIN Backup withholding may apply to reportable payments
Vendor confirms foreign status Use the appropriate Form W-8 instead of Form W-9 Form W-9 is generally not used to document foreign status

How Tax1099 Helps Businesses Manage Vendor W-9s

Tax1099 can move vendor W-9 requirements into the onboarding and filing workflow rather than leaving them as a year-end task.

Tax1099 allows businesses to electronically request vendor W-9 and W-8 information, to manage recipient information, and perform real-time or bulk vendor TIN verification. The TIN matching feature can validate many name/TIN records and flag records requiring follow-up with the vendor.

With vendor information in place, the same process can be used to prepare and e-file appropriate Forms 1099.
