To complete a W-9 online, match the taxpayer’s reporting name, federal tax classification and identification number, then review the applicable certification. The Check Stubs Online builder prepares the March 2024 certificate and instructions. Give the reviewed W-9 to the person or business requesting it; it is not an IRS tax-return submission.
Reviewed October 29, 2026 · U.S. taxpayer-identification certificates using the current March 2024 revision. The identity examples are fictional and assume the stated ownership and federal tax treatment.
The W-9 online generator brings the certificate’s entries into one preview. Start with the actual taxpayer record: a business’s public name, its legal organization and its federal tax identity do not always produce the same entries.
What does the W-9 requester need from you?
A W-9 supplies taxpayer-identification information for the requester’s reporting process. The IRS’s explanation of Form W-9 covers requests connected with payments, certain property transactions, debt cancellation and other information-return situations. It is not limited to freelancers sending an invoice.
Confirm which person or organization is requesting the certificate and which account or payment relationship it concerns. For example, the company buying services and the payment processor handling a separate account may have different onboarding procedures. Follow the verified requester’s instructions for its own record.
The form is not a record of how much a customer has already paid. Our 1099-NEC preparation guide explains a payer’s separate annual payment-reporting workflow. A W-9 helps establish the payee information used in that process; it does not replace the payment ledger or resulting information return.
If an employer is asking for employee withholding instructions, check whether the intended document is W-4. The W-9 and W-4 comparison can help identify that difference before you enter sensitive information into the wrong tool.
Which records should you collect before opening the builder?
Gather the taxpayer’s reporting name, any separate business name, the applicable federal classification, mailing address and correct TIN. Resolve a mismatch in the underlying records before trying to make the preview look complete.
| Entry | Useful source information | Question to resolve |
|---|---|---|
| Reporting name | The name associated with the taxpayer’s tax record. | Is this the taxpayer, or only the public business name? |
| Federal classification | The actual ownership and tax treatment, including an applicable election. | How is the named taxpayer classified for federal tax purposes? |
| Identification number | The correct number for that taxpayer and permitted ID type. | Does the number belong with the reporting name? |
| Address | The mailing information intended for this reporting relationship. | Can the requester use it for the intended correspondence? |
| Certification | Relevant IRS notices and the facts behind any exemption. | Which statements and codes actually apply? |
The tool separates SSN, EIN, ITIN and ATIN choices. Seeing an option in a menu does not make it suitable for every taxpayer. Use the type permitted for the particular record rather than choosing whichever accepts the number you happen to have nearby.
Do not use a customer account number in place of a TIN. The builder has a separate optional account-number field. Keeping these entries distinct also makes the final review easier: a reference used by one requester should not be mistaken for a federal identifier.
How do you match the taxpayer name and federal classification?
The builder asks whether the taxpayer is a U.S. person for federal tax purposes before you choose a classification. This is broader than citizenship, and possession of a U.S. address or identification number does not settle the question. Foreign persons generally need the appropriate W-8 form or Form 8233 instead; check the circumstances with the requester. The IRS requester instructions address the relevant status and withholding distinctions.
For a U.S. sole proprietor or disregarded entity, the current interface directs you to enter the owner on Line 1 and the separate business name on Line 2. Keep the two fields distinguishable in the preview. Adding a trade name to Line 2 does not change who owns the taxpayer identification number.
Select the classification that describes the Line 1 taxpayer. The tool offers individual/sole proprietor, corporate, partnership, trust/estate, LLC and other entries. Its LLC selection requires the applicable C, S or P tax classification. A disregarded single-member LLC follows its owner’s classification instead of selecting LLC simply because those letters appear in its business name.
The IRS’s single-member LLC guidance specifically distinguishes the owner’s number used for W-9 income-reporting purposes from an EIN belonging to the disregarded LLC. That distinction can matter even when the business already has an EIN for another purpose.
Read the complete pairing on the preview: the Line 1 name, the classification and the selected number. If an entry disagrees with the records, correct the source information or obtain clarification rather than choosing a different classification merely to proceed.
How can two LLCs produce different W-9 entries?
Consider two fictional U.S. businesses. Taylor Reed owns Reed Field Studio LLC, assumed to be disregarded for federal income tax purposes with a U.S. individual owner. A different business, Alder Lab LLC, is assumed to have valid S-corporation tax treatment. The table illustrates why the same state-law label does not answer every W-9 question.
| Certificate entry | Reed Field Studio LLC | Alder Lab LLC |
|---|---|---|
| Assumed tax treatment | Disregarded entity owned by Taylor Reed. | LLC taxed as an S corporation. |
| Line 1 | Taylor Reed. | The entity’s actual tax-reporting name. |
| Line 2 | Reed Field Studio LLC. | A separate business name, if applicable. |
| Classification | The individual owner’s classification. | LLC with tax classification S. |
| TIN pairing | The owner’s permitted SSN or EIN. | The EIN corresponding to the entity’s reporting name. |
The first example follows the cited single-member LLC rule. The LLC selection and C/S/P codes are shown in the current W-9 instructions and classification chart. Neither example supplies an invented identification number. In an actual certificate, check the real ownership, election and taxpayer records before adopting an entry.
Use this comparison as a review method: establish the assumed facts, identify the taxpayer and then match the fields. Do not copy the first business’s treatment just because your business also has one owner, or the second business’s treatment because an S-corporation election is being considered rather than already applicable.
How should the address, additional checkbox and exemption codes be reviewed?
Enter the mailing address in the corresponding fields and check the full address on the certificate. The builder separates the street, city, state and postal information, with additional location fields where relevant. Optional requester details and account references should describe the actual relationship without changing the taxpayer identity.
Line 3b has a particular ownership context. It concerns relevant partnerships, partnership-classified LLCs, trusts or estates with foreign partners, owners or beneficiaries when supplying the form to a partnership, trust or estate in which they hold an ownership interest. It is not a general checkbox for having an overseas customer. Read the line-specific instructions if those conditions might apply.
The exemption menus contain numbered exempt-payee codes and lettered FATCA-reporting codes. Leave a code unset unless the instructions support that exemption for the actual taxpayer and situation. FATCA exemption codes concern accounts maintained outside the United States; they are not a general business credential.
Before selecting a code, be able to explain which instruction applies. A business name or a desire to avoid withholding is not a sufficient basis. The preview can display a chosen code without deciding whether the underlying exemption exists.
What should you check before certifying or signing?
Read the certification as a statement about your actual circumstances. The builder’s notice checkbox is specifically about being currently subject to backup withholding after an IRS notice concerning unreported interest or dividends. It crosses out certification item 2. It is not intended for every IRS letter or every unresolved tax issue.
The IRS backup-withholding overview describes a current 24% rate and different triggers, including incorrect taxpayer information and interest/dividend reporting issues. A checkbox or newly downloaded PDF does not by itself resolve an existing notice or establish that a payer has corrected its records.
Check the form’s Part II instructions for the applicable signature requirement. Certain situations require a signed certification; some specified payments generally require the correct TIN without the same signature requirement, subject to the instructions. A requester may also ask for a signature. Do not treat every use of W-9 as having identical certification steps.
The current tool offers printing and signing later, or drawing a signature and explicitly applying it after reviewing the certification and signing date. If you choose to sign later, inspect the blank signature and date areas and complete the required signing process before delivery. Apply only the appropriate person’s authorized signature.
How do you review the PDF and give it to the requester?
The builder uses the March 2024 revision rather than asking you to choose an annual tax-return year. Its current packet contains six IRS pages, including the completed certificate and instructions. Inspect the certificate itself and distinguish it from the explanatory pages in the preview.
- Check the identity chain. Read the reporting name, classification and TIN together. Review the optional business name separately.
- Review the remaining entries. Confirm the address, applicable codes, ownership checkbox and any account reference.
- Inspect the certification. Check the notice setting and the signature/date choice against what is required.
- Review the order. Check the current price, delivery email and terms before purchasing the PDF. The IRS also provides a blank W-9 without a purchase.
- Arrange requester delivery. Use the recipient’s verified process and retain an appropriate copy or confirmation.
The product’s private order link is for accessing the prepared document. Keep it restricted to the intended people. It is not an instruction to publish the certificate, and completing checkout does not automatically deliver it to the business requesting your W-9.
Ask the requester which delivery method it accepts. The IRS requester instructions describe requirements for electronic W-9 systems; a saved PDF alone does not establish that every possible submission method meets those requirements. Keep the preparation and delivery steps distinct.
W-9 online generator questions
Is a separate 2026 W-9 required just because the year changed?
The current tool uses the March 2024 revision. W-9 is an identification certificate, not an annual income-tax return. Check the latest IRS revision and whether the requester needs updated taxpayer information.
Should I choose LLC whenever my business name ends with LLC?
Determine the actual federal treatment first. The builder distinguishes a disregarded entity using its owner’s classification from an LLC using a C, S or P classification.
Does a W-9 show the income I have earned?
It supplies identification and certification information. Payment statements and applicable information returns serve different purposes. See how W-9 differs from W-2 for another common document distinction.
Can I use the requester’s account reference as the tax ID?
No. The tool provides a separate optional account field. Review the actual taxpayer number and its permitted type before completing the certificate.
Can I leave the signature blank in the builder?
The print-later option leaves signing fields blank. Check the applicable certification requirements and requester instructions, then complete the necessary signature process before sharing.
Does buying the PDF send the W-9 to the IRS?
No. This is PDF preparation. Give the reviewed certificate to the verified requester through its intended process.
