Letter 4800C is mailed to taxpayers informing them that the IRS is proposing a deficiency or disallowing a claim for refund or a credit for a subsequent period’s estimated tax.
This notice or letter may include additional topics that have not yet been covered here. Please check back frequently for updates.
The first thing to do is to check the return address to be sure it’s from the IRS and not another agency.
Call the IRS immediately as you may be a victim of tax-related identity theft. Someone else may have used your personal information to file this return.
Note: Authorized third parties may assist taxpayers, but the taxpayer must be present on the phone or in-person.
Complete and send the IRS a Form 2848, Power of Attorney and Declaration of Representative, to authorize someone (such as an accountant) to contact the IRS on your behalf.
To support the entries on your return and complete processing of your tax return you may need to submit documents and information requested in the Letter 4800C, for example:
Do Not file a Form 1040-X , Amended U.S Individual Income Tax Return, at this time. Your account will be corrected based on the review of documents submitted.
The review process could take anywhere from 45 to 180 days. If you have not received your refund or heard from the IRS after that time, contact the IRS at the toll-free number listed at the top right corner of your notice.
If the IRS accepts your documentation, the IRS will send you a letter stating that it accepts your return as filed. If your documentation is not accepted, you will receive a letter explaining why. If you disagree, you may request a conference with the IRS Independent Office of Appeals (Appeals).
If you disagree, in the enclosed envelope, send the statement and photocopies of your original documents that support your position. If you’re unable to verify an amount you claimed, explain the issue and how you determined the amount. Include the Response Form or a complete copy of this letter.
If you have submitted all of your documentation and do not agree with the proposed changes to your account, request your case be forwarded to Appeals for review.
If you agree with the proposed changes to your account, sign and return the enclosed form. You will receive a bill advising you of the amount owed. The amount owed will include interest and penalties that will continue to accrue until the balance is paid in full.
If the IRS doesn’t accept the documentation submitted, you will receive a letter explaining why. If you disagree with the decision, you may request an Appeals conference. Appeals is independent from the IRS office that sent you this letter. If you don’t wish to appeal or you disagree with the Appeals decision, you may have the right to take your case to court.
