Accuracy Checks

Validation checks

Our AI performs these checks on every W-9 form to ensure accuracy and compliance.

Name-TIN Match

Ensures the legal name on Line 1 matches IRS records exactly. Flags mismatches between name and TIN before submission.

Tax Classification

Confirms exactly one classification box is checked on Line 3 and that it is correct for the entity type. Validates LLC code letters.

TIN Format

Validates the TIN format: SSN as 9 digits or EIN as XX-XXXXXXX. Detects transposed digits and common input errors.

Signature Required

Verifies the form is signed and dated in Part II. A W-9 is invalid without a signature under penalty of perjury.

Common Mistakes

Errors to avoid

These are the most common mistakes when filling out W-9 forms.

Name does not match IRS records

The most common error. Your name on Line 1 must match exactly what the IRS has on file. A mismatch can trigger backup withholding for the payer.

Wrong TIN

Confusing SSN with EIN, or transposing digits, causes processing failures. Verify your TIN against your Social Security card or IRS CP 575 letter.

Wrong tax classification for LLC

A single-member LLC uses the owner's SSN and should check "Individual/Sole Proprietor," not the LLC box with an entity EIN.

Missing signature and date

The form is legally invalid without a signature and date in Part II. This is a frequent oversight that forces re-submission.

Leaving Line 1 blank

Your legal name is required. Leaving it blank or using a nickname instead of your full legal name will cause the form to be rejected.

Sending W-9 to the IRS

You do not send a W-9 to the IRS. Give it to the payer who requested it. The payer keeps it on file for their records.

FAQ

Frequently asked questions

What is a W-9 form?
IRS Form W-9 (Request for Taxpayer Identification Number and Certification) is used by businesses to collect taxpayer information from vendors, contractors, and freelancers. The payer uses the TIN provided on the W-9 to prepare IRS Form 1099 for year-end tax reporting.
Who needs to fill out a W-9?
Any US person (citizen, resident alien, or entity) who receives reportable payments must provide a W-9 to the payer. This includes independent contractors, freelancers, consultants, vendors, and other non-employee payees. If you earn $600 or more in a tax year from a single payer, they will need your W-9 to file a 1099-NEC.
What is the difference between W-9 and W-4?
A W-9 is for independent contractors and vendors. It collects your Taxpayer Identification Number (TIN) so the payer can report payments on a 1099. A W-4 is for employees. It tells the employer how much federal income tax to withhold from each paycheck. They serve completely different purposes and are filled out by different types of workers.
What information is required on a W-9?
A W-9 requires: Line 1: your full legal name. Line 2: your business name (if different). Line 3: federal tax classification (individual, C Corp, S Corp, Partnership, Trust/Estate, LLC, or Other). Line 4: any applicable exemptions. Lines 5 and 6: your address. Line 7: your account numbers (optional). Part I: your TIN (SSN or EIN). Part II: your signature and date. The form is invalid without a signature.
What is a Taxpayer Identification Number (TIN)?
A TIN is the number the IRS uses to identify taxpayers. For individuals, the TIN is typically a Social Security Number (SSN) consisting of 9 digits. For businesses, it is an Employer Identification Number (EIN) in the format XX-XXXXXXX (9 digits with a hyphen). Resident aliens without an SSN may use an Individual Taxpayer Identification Number (ITIN).
How do I fill out Line 3: Federal tax classification?
Line 3 offers seven classification options: Individual/Sole Proprietor, C Corporation, S Corporation, Partnership, Trust/Estate, LLC (with a code letter), and Other. Check only one box. For LLCs, also enter a code letter after the LLC box: C for C Corporation, S for S Corporation, P for Partnership, or leave blank if disregarded as an entity separate from its owner.
What is backup withholding?
Backup withholding is a 24% tax the IRS requires payers to withhold from payments when a payee's TIN is missing, incorrect, or the IRS has notified the payer of underreporting. If backup withholding applies, the payer withholds 24% of each payment and sends it to the IRS. You can avoid backup withholding by providing a correct TIN on your W-9 and certifying that you are not subject to backup withholding.
Do I need to send a W-9 to the IRS?
No. You do not send a W-9 to the IRS. You give the completed W-9 to the business or individual who requested it (the payer). The payer keeps it on file for at least four years after the tax year in which payments were made. The payer uses the TIN from your W-9 to file Form 1099 with the IRS.
How often do I need to submit a new W-9?
There is no annual requirement to submit a new W-9. You only need to provide a new W-9 when your legal name changes, your business entity structure changes, your TIN changes, or when a payer requests a fresh certification. Otherwise, the W-9 you previously submitted remains valid.
What happens if I don't provide a W-9?
If you refuse to provide a W-9 or provide an incorrect TIN, the payer may be required by the IRS to apply backup withholding at a rate of 24%. This means 24% of your payments will be withheld and sent to the IRS until you provide a valid TIN. You may also face penalties from the IRS for intentionally supplying false information.
Can I fill out a W-9 online?
Yes. You can fill out a W-9 online with DocuQueue. Enter your information, review the filled form, and download the completed PDF in seconds. No software installation required. You can also use our AI form filler to auto-populate fields from a photo or document scan.
What is the difference between W-9 and 1099?
A W-9 is a form you fill out and give to a payer to provide your Taxpayer Identification Number. A 1099 is a form the payer files with the IRS at the end of the tax year to report how much they paid you. The payer uses the TIN from your W-9 to complete the 1099. You receive a copy of the 1099 for your own tax filing.
