If Discover has sent you an IRS consent form, they are asking your permission to pull your tax transcript directly from the IRS to confirm the income you reported. The form is IRS Form 4506-C, and federal law requires your signed authorization before any lender can see your return data. Your signature must reach the IRS within 120 days or the request expires. Refusing or ignoring the request can mean a denied application, a lowered credit limit, a frozen account, or a closed one, depending on what triggered the ask.
Why Discover Is Asking
Discover doesn’t request tax consent on every account. The ask is triggered by specific situations where the income figure you entered isn’t enough on its own to satisfy underwriting or lending regulations. Common triggers include:
- A new student loan or personal loan application that requires independent income confirmation before approval.
- A credit limit increase you requested, or one Discover is considering offering you.
- A periodic account review. Discover has been running batch verification of existing cardholders, so you can receive a request even if nothing about your account changed recently.
- An income update you entered that differs significantly from what you previously reported.
- A hardship or debt relief request, where Discover needs to confirm your actual financial situation before adjusting terms.
The common thread is independent verification. A transcript pulled straight from the IRS is the most reliable source, and responsible lending rules effectively require it in many of these situations.
What Form 4506-C Actually Authorizes
Form 4506-C is titled “IVES Request for Transcript of Tax Return.” It authorizes an approved participant in the IRS Income Verification Express Service (IVES) to receive a summary of your filed return data.1Internal Revenue Service. Income Verification Express Service The IRS does not send Discover a copy of your actual return. It sends a transcript, which is a standardized summary showing figures like adjusted gross income, wages and other income reported to the IRS, filing status, and basic identifying information. Itemized deduction detail, bank account numbers, and asset information are not part of it.
The legal ground is Section 6103 of the Internal Revenue Code, which makes tax returns confidential and blocks outside access unless you consent.2Office of the Law Revision Counsel. 26 US Code 6103 – Confidentiality and Disclosure of Returns and Return Information Section 6103(c) is what lets you designate a third party like Discover to receive it. The authorization is narrow: Discover can use the transcript only for the purpose stated on the form, and any unauthorized use or redisclosure carries penalties.3Internal Revenue Service.

It’s also time-limited. The IRS must receive your signed form within 120 days of the signature date, and once the transcript is delivered, that authorization is spent. Discover cannot use one signed 4506-C to keep pulling records indefinitely. If they need updated information later, they need a new signed form.
How to Fill It Out Without Getting Rejected
You’ll usually sign the form electronically through Discover’s secure portal or a verification partner. Before you sign, verify that the details on the form match what the IRS has on file. Mismatched information is the most common reason the IRS rejects these requests, and a rejection means starting over.
- Legal name: use the exact spelling on your most recent tax return. If you changed your name and haven’t updated the Social Security Administration, use the name SSA still has on record.
- Social Security Number or ITIN: check every digit. One transposed number causes a rejection.
- Mailing address: match the address on your most recent filed return, not necessarily your current address.
- Tax years: confirm the years listed are ones you’ve actually filed. If Discover wants 2024 and 2025 but you haven’t filed 2025 yet, the IRS has nothing to send for that year.
If you filed a joint return, both spouses’ information may need to appear on the form. Discover or its verification partner should have already filled in their IVES participant details on line 5a. Glance at that section to make sure it’s complete, but you shouldn’t need to enter anything there yourself.3Internal Revenue Service. Form 4506-C – IVES Request for Transcript of Tax Return
What Happens After You Sign
Once submitted, Discover or its IVES-authorized partner transmits the form to the IRS. Using the IVES faxing option, transcripts are typically returned in about two to three business days, excluding weekends and holidays.4Internal Revenue Service. Income Verification Express Service Faxing for Participants The total turnaround from your signature to a decision on your application or review can run a bit longer depending on Discover’s internal review.
The IRS charges IVES participants $4 per transcript.5Internal Revenue Service. Income Verification Express Service for Participants Discover pays this, not you. You should never be asked to pay out of pocket for the verification.
If the IRS rejects the request because of mismatched information, Discover comes back to you with a corrected form. That resets the 120-day clock and adds processing time to whatever triggered the request in the first place.
What Happens If You Refuse
You are not legally required to consent. But the practical consequences depend on why Discover asked.
For a new application, refusing means Discover can’t verify your income through official channels, and they will either deny the application or send a notice of incompleteness. Under federal credit rules, if you’re denied you’re entitled to a specific reason, either automatically or on request within 60 days.6Consumer Financial Protection Bureau. Regulation B – Notifications
For an existing account, the stakes are higher than most people expect. When Discover flags an existing account for verification and you don’t comply, they can freeze the account, lower your credit limit, or close it. Cardholders who’ve gone through this report that Discover locks online access and declines transactions while the verification is pending, and closes accounts when the form isn’t returned by the deadline. If you do provide consent and the transcript shows income much lower than what you reported to Discover, the account can also be closed or the limit reduced.
Privacy Protections Once the Transcript Is Shared
The protections on your tax data are unusually strong compared to most financial information you share with a bank. Section 6103(c) restricts Discover to using the transcript only for the purpose you consented to. That restriction has teeth: under 26 U.S.C. ยง 7213, willful unauthorized disclosure of tax return information is a felony, punishable by a fine up to $5,000, imprisonment up to five years, or both.7Office of the Law Revision Counsel. 26 US Code 7213 – Unauthorized Disclosure of Information Federal law also gives you a civil cause of action for damages if your transcript is improperly inspected or shared. Discover cannot legally take a transcript pulled to verify credit card income and route it to an unrelated department.
Canceling or Letting the Authorization Expire
Because Form 4506-C is a one-time transcript pull with a built-in 120-day expiration, revocation is less involved than with an ongoing authorization. If the IRS hasn’t yet processed the request, contact Discover directly to withdraw your consent, since they’re the ones transmitting the form. If you decide to comply, the authorization does not linger on your IRS file or grant Discover future access beyond the transcript specifically requested.
A different form, IRS Form 8821, grants ongoing access to your tax information rather than a single transcript, and revoking it involves filing a new Form 8821 or using its line 5 to delete the prior authorization.8Internal Revenue Service. Instructions for Form 8821 That process doesn’t apply to a 4506-C request from Discover, which is the form nearly all cardholders will see.
