Are You Exempt From Backup Withholding? Rules, W-9, and Refunds

If you’re a U.S. citizen or resident alien, you’re exempt from backup withholding as long as you give each payer a correct taxpayer identification number and the IRS hasn’t notified that payer you underreported interest or dividends on a past return.¹ Certain organizations — corporations, government agencies, tax-exempt entities, and others listed by statute — are categorically exempt no matter their filing history. When someone isn’t exempt, the payer takes a flat 24% out of payments like interest, dividends, and contractor fees before the recipient sees a cent.²

Who Qualifies as Exempt

For individuals, the rule is short. Provide a correct Social Security number or ITIN to the payer, report all your interest and dividends on your returns, and you stay exempt. “U.S. person” for this purpose covers U.S. citizens, resident aliens, domestic partnerships and corporations, most estates, and certain domestic trusts.³

For entities, the exemption is categorical. The Internal Revenue Code and its regulations list types of organizations that don’t get 24% withheld regardless of anything else, and Form W-9 pairs each type with a numbered code you enter on Line 4.⁴ The exempt payee codes are:³

Code 1: Tax-exempt organizations under section 501(a), IRAs, and custodial accounts under section 403(b)(7)
Code 2: The United States or any of its agencies or instrumentalities
Code 3: A state, the District of Columbia, a U.S. territory, or any of their political subdivisions and agencies
Code 4: A foreign government or any of its political subdivisions and agencies
Code 5: A corporation
Code 6: A dealer in securities or commodities registered in the United States
Code 7: A futures commission merchant registered with the Commodity Futures Trading Commission
Code 8: A real estate investment trust
Code 9: An entity registered under the Investment Company Act of 1940
Code 10: A common trust fund operated by a bank
Code 11: A financial institution as defined under section 581
Code 12: A nominee or custodian known in the investment community as a middleman
Code 13: A trust exempt from tax under section 664 or described in section 4947

One caveat trips corporations up. The corporate exemption (Code 5) doesn’t cover every payment type. Corporations remain subject to backup withholding on attorney fees and on payments reported on Form 1099-K, so a corporation receiving legal settlement proceeds or payment card transactions still needs a correct TIN on file. The exempt code doesn’t override those specific reporting categories.³

Wages paid to employees don’t fall under backup withholding at all. They’re already covered by regular income tax withholding through Form W-4. Payments to foreign persons that fall under separate withholding rules or tax treaties are also excluded, so the same income isn’t taxed through two systems.

What Can Knock You Out of Exempt Status

Backup withholding kicks in when someone doesn’t cooperate with basic tax identification requirements. A payer must start withholding 24% in any of these situations:²

You didn’t give the payer a TIN in the required way, or the number you gave doesn’t match IRS records.
The IRS determined you underreported interest or dividends on a prior return. Before withholding starts for this reason, the IRS must mail you at least four notices over a period of at least 120 days, so it doesn’t come out of nowhere.
You didn’t certify that you’re not subject to backup withholding when opening an account or starting to receive payments.

The verification loop works like this. The IRS matches what a payer reports against what shows up on your return. If there’s a mismatch, the payer gets a CP2100 or CP2100A notice and sends you a “B notice” asking you to fix it. Ignore the B notice and withholding begins. If the same mismatch reappears within three years, the second B notice requires more than a fresh W-9: you’ll need a copy of your Social Security card, or an IRS Letter 147C for an EIN.⁵

Payers who fail to withhold when they should can be held liable for the tax themselves, which is why banks and businesses treat W-9 requests seriously.

How to Certify Your Exemption on Form W-9

Form W-9 is where you tell a payer you’re exempt. The form is available on the IRS website and functions as your official certification.⁶

For individuals: enter your legal name, address, and Social Security number, then sign. That signature makes three declarations under penalty of perjury — that the TIN is correct, that you’re a U.S. person, and that you aren’t currently subject to backup withholding for underreporting.³ If the IRS has already told you you’re subject to backup withholding for underreporting, cross out the certification about not being subject to backup withholding before you sign. You can’t certify something that isn’t true.

For an exempt entity, Line 4 is where the exempt payee code from the list above goes. A separate FATCA code sits in the adjacent field if applicable, though U.S. financial institutions with domestic accounts can leave FATCA blank or mark it “N/A.”³

The completed W-9 goes to the payer, not the IRS. Financial institutions often accept it through a secure online portal; smaller businesses may ask for a mailed or emailed copy. If your legal name or TIN changes, send a new form so your exemption stays current.

How to Stop Backup Withholding Once It Has Started

If 24% is already coming out of your payments, the fix depends on why it started. The IRS runs two separate programs.

Incorrect or Missing TIN (the “B” Program)

After a first B notice, submit a properly completed Form W-9 with the correct number to the payer, and withholding stops. On a second B notice within three years, a fresh W-9 isn’t enough. You need a copy of your Social Security card, or an IRS Letter 147C confirming an EIN.⁵

Underreported Interest or Dividends (the “C” Program)

Here, you have to fix the underlying tax problem: file any missing returns with the correct figures, or amend earlier returns to report the right amounts.⁷ You don’t need to contact the IRS separately to say you’ve corrected it. Filing the return is the notice. Once the IRS processes the corrected return and confirms the issue is resolved, it tells the payer to stop withholding.

Don’t wait either way. Every payment that goes out while you’re subject to backup withholding loses 24% at the source, and the payer can’t refund that money to you directly. You’ll wait until you file your annual return to get it back.

Recovering Amounts Already Withheld

Money withheld during the year isn’t lost. It works like an estimated tax payment. When you file your federal return, report the withheld amount as federal income tax withheld. Your Form 1099 — whether 1099-INT, 1099-DIV, 1099-NEC, or another variant — shows the backup withholding figure in the relevant box.²

If you’re a partner or shareholder in a partnership or S corporation that had backup withholding applied to its payments, the individual partners or shareholders claim their respective shares on their own returns. The entity itself doesn’t get the credit.² Withholding often exceeds what you’d actually owe, so the extra comes back as a refund. It’s slow money, though. Until you file, you’ve effectively made the IRS an interest-free loan.
