IRS Notice CP21B: Adjusted Return — Balance Due

IRS CP21B 通知是什么意思？

A CP21B confirms the IRS made changes to your tax account — often from an amended return or a requested adjustment — and the result is a balance due. The notice details the adjustment and the amount owed, including any penalties and interest.

您为什么会收到 CP21B？

An amendment or correction to your return increased your tax liability, or an adjustment you requested had the side effect of creating a balance.

如何回应 CP21B 通知

If the change is correct, pay the balance by the due date or set up an installment agreement to avoid additional penalties. If you disagree with the adjustment, contact the IRS within 60 days with documentation supporting your position.

如果忽视会发生什么？

Penalties and interest accumulate and the account enters the normal collection cycle, eventually leading to levy notices if the balance remains unpaid.

常见解决方式
