Yes, you should include your IP (Identity Protection) PIN when filing an amended return. The IP PIN is a six-digit number assigned to eligible taxpayers to help prevent the misuse of their Social Security number on fraudulent federal income tax returns.
According to the retrieved information, if you have an IP PIN, you must provide it on your return, including any amended return you file. Failure to include the IP PIN will result in the electronic return being rejected and the paper return being delayed. This requirement is reiterated multiple times across various IRS publications and instructions, emphasizing its importance.
For electronic returns, the IP PIN must be included along with other required information such as your PIN, last name, date of birth, and adjusted gross income (AGI) from the prior year’s federal income tax return. For paper returns, the IP PIN should be entered on the Form 1040, which must be submitted along with the amended return.
Therefore, to ensure your amended return is processed without unnecessary delays, it is crucial to include your IP PIN.
