IRS Instruction W-9 – IRS Forms, Instructions, Pubs 2026 – In the ever-evolving landscape of tax compliance, understanding the IRS Form W-9 instructions is crucial for businesses, financial institutions, and anyone required to report payments to the IRS. Form W-9, officially titled “Request for Taxpayer Identification Number and Certification,” helps requestors obtain essential information from payees to ensure accurate reporting and avoid unnecessary withholding. This SEO-optimized guide breaks down the latest instructions for requestors (Rev. January 2026), highlighting key updates, requirements, and best practices to help you stay compliant.
What Is Form W-9 and Its Purpose?
Form W-9 is a critical IRS document used by requestors—such as payers, withholding agents, or financial institutions—to collect a payee’s Taxpayer Identification Number (TIN), which could be a Social Security Number (SSN), Individual Taxpayer Identification Number (ITIN), or Employer Identification Number (EIN). The form also includes certifications under penalties of perjury that confirm the TIN’s accuracy, the payee’s U.S. status, exemption from backup withholding due to underreporting, and any applicable Foreign Account Tax Compliance Act (FATCA) codes.
The primary purpose is to prevent backup withholding at a 24% rate on reportable payments, such as interest, dividends, nonemployee compensation, and sales of digital assets. Without a valid Form W-9, requestors must presume the payee is foreign and apply withholding under chapters 3 and 4 of the Internal Revenue Code. This form is exclusively for U.S. persons (including resident aliens); foreign individuals or entities should use the W-8 series instead.
Requestors use Form W-9 for various scenarios, including:
- Reporting income on information returns like Forms 1099-INT, 1099-DIV, or the new 1099-DA for digital assets.
- Real estate transactions, debt cancellations, or contributions to IRAs.
- Payments subject to withholding under sections 1441–1446, such as U.S. source income to partnerships or transfers of U.S. real property.
By obtaining a properly completed Form W-9, requestors can avoid liability for uncollected withholding taxes.
What’s New in the 2026 IRS W-9 Instructions?
The IRS has updated the instructions for Form W-9 (Rev. January 2026) to address emerging tax issues, particularly in digital assets and reporting thresholds. These changes reflect provisions from the One Big Beautiful Bill Act (OBBBA) and recent Treasury decisions. Here’s a breakdown of the key updates:
- Digital Asset Broker Certifications: A new checkbox in Part II allows U.S. digital asset (DA) brokers (excluding certain registered investment advisers) to certify their exempt status from information reporting under Regulations section 1.6045-1(c)(3)(i)(B)(12). This aligns with Treasury Decision 10000 and Notice 2024-56, facilitating exemptions for DA sales effective January 1, 2025.
- Exempt Payee Code Changes: New code 14 is designated for U.S. DA brokers. Transitional relief under Notice 2025-33 extends no backup withholding on DA sales through 2026 and penalty relief for good faith efforts in filing Forms 1099-DA through 2025 (extended to 2027 for certain TIN issues).
- Reporting Thresholds Increased: Backup withholding and information reporting thresholds under sections 6041 and 6041A rise to $2,000 for payments after 2025, with inflation adjustments starting in 2027.
- De Minimis Rule for Third-Party Networks: Under section 6050W, reporting is required for transactions exceeding $20,000 and 200 transactions after 2024. Backup withholding exceptions apply if prior-year transactions were reportable.
- Clarifications for Sole Proprietors and Disregarded Entities: Sole proprietors must use their SSN (or ITIN), not an EIN. Disregarded entities (e.g., single-member LLCs) must provide the owner’s TIN to reduce mismatch notices.
- Line 3 Updates: Line 3a clarifies tax classifications for LLCs, and line 3b requires flow-through entities to indicate foreign partners or beneficiaries.
- OBBBA-Related Reporting: New deductions for qualified car loans, cash tips, and overtime may require updated Forms W-9, with guidance in Notice 2025-57.
These updates ensure the form adapts to digital economy growth and recent tax law changes.
When Should Requestors Ask for Form W-9?
Request Form W-9 from any U.S. person before making reportable payments to establish their TIN and U.S. status. Key situations include:
- Paying nonemployee compensation over $600 annually.
- Reporting interest, dividends, or patronage dividends.
- Handling barter exchanges, third-party network transactions, or digital asset sales.
- Withholding on U.S. source income to partnerships or real property transfers.
For joint accounts, obtain a form from each U.S. holder. Participating foreign financial institutions (PFFIs) must request it from U.S. account holders. If no Form W-9 is provided, presume foreign status and withhold accordingly.
How to Request Form W-9: Tips for Requestors?
Requestors can use the official IRS Form W-9 or develop a substitute form that is substantially similar, including all required certifications. Highlight the perjury statements and avoid adding unrelated provisions.
- Electronic Submissions: Implement systems that verify accuracy, allow electronic signatures under perjury, and provide hard copies on request.
- Providing Instructions: Only furnish the full instructions if the payee asks or if backup withholding is required.
- Awaiting-TIN Procedures: If a payee is applying for a TIN, allow 60 days before starting backup withholding. Use reserve or alternative rules for large withdrawals.
- TIN Matching: Utilize IRS e-Services to validate TINs and names pre-filing to minimize notices.
Update records if a payee provides new information, such as a name change.
Key Requirements for Payees Filling Out Form W-9
While these instructions are for requestors, understanding payee obligations helps ensure compliance:
- Provide accurate name, TIN, and tax classification (e.g., individual, LLC).
- Check line 3b if the entity has foreign partners (for flow-throughs).
- Enter exempt payee or FATCA codes if applicable.
- Sign and date under penalties of perjury, including the new DA broker checkbox if qualifying.
ITINs expire after three years of non-use; renew via Form W-7.
Understanding Backup Withholding Rules
Backup withholding at 24% applies if:
- No TIN is provided.
- The TIN is incorrect (per IRS notices).
- Interest or dividends are underreported.
- No certification is given.
Exemptions include certain organizations (e.g., 501(c)(3) nonprofits, governments) and payments like wages or pensions. No backup withholding on digital asset sales through 2026. Requestors are liable for any unwithheld amounts, so diligence is key.
| Scenario | Backup Withholding Rate | Exemption Possible? |
|---|---|---|
| No TIN Provided | 24% | No, unless awaiting-TIN |
| Incorrect TIN | 24% | Yes, with valid Form W-9 |
| Digital Asset Sales (through 2026) | 0% (transitional relief) | N/A |
| Third-Party Networks (de minimis) | 24% if thresholds met | Yes, if prior-year reportable |
Penalties for Non-Compliance
Failing to obtain a Form W-9 or withhold backup taxes can lead to:
- Liability for uncollected withholding.
- Penalties under sections 6721–6724 for inaccurate or late information returns (up to $310 per form in 2026).
- Transitional relief for digital assets avoids penalties for good faith efforts through 2027.
Always report withheld amounts on Form 945 and deposit per IRS schedules.
