The IP Pin will change each and every year. Are you using your IP Pin for 2024?
You can get an Identity Protection pin here, or if you lost your IP PIN, you can go here to Retrieve IP PIN.
Here's how you can fix a reject:
Sign in to your account and select the Fix my return button. Follow any “fix it” instructions to update the information causing the rejection.
Note: Not all rejections will have explicit guides to fix the information. You’ll need to navigate to the program area to address the cause of the rejection.
Time-saving Tip: If what you originally entered is correct, you won't be able to e-file. There's probably a data mismatch at the government, a dependent that's already been claimed, or some other situation beyond your control that prevents your return from being e-filed. In this case, your only option would be to print and mail in your return. This article will give you instruction on how to print and mail your return.
