IRS Notice CP134B – Adjusted Amount Due
IRS Notice CP134B is sent to taxpayers to notify them that there is a discrepancy in the amount of tax due from what was reported on their tax return.
Why Did I Receive IRS Notice CP134B?
You received notice CP3134B because the IRS detected a difference between the tax deposits credited to your account and the amount reported on your tax return. This typically happens with estimated quarterly tax payments or Form 941.
Next Steps
Carefully review your IRS C134B notice. It will detail the adjusted balance, including any penalty and interest fees. Next, you should:
- Compare Your Records. Look at your payroll records, bank statements, and tax deposit receipts, matching them against the tax period outlined on the notice.
- Review Your Tax Transcripts. Pull your transcripts from your IRS account to see how and when the IRS credited your payments. Check to make sure they are not misapplied to the wrong quarter or tax year.
If you agree with the amount assessed:
- Submit payment for the total due. Make sure payment is made by the due date listed on your CP134B notice to avoid additional penalties and interest fees.
- If you can’t pay the amount in full, pay as much as you can and contact the IRS at the number listed on your notice to discuss your payment options for the remaining balance.
If you think there’s a mistake:
- Contact the IRS at the number listed on the CP134B notice or contact them by mail. Just complete the enclosed Contact Information section, detach it, and send it to the IRS with any relevant documentation and statements.
Failure to pay or respond will result in additional penalty and interest fees. Ongoing non-compliance will also result in escalation of enforcement actions, such as wage garnishment, liens, and levies.
