IRS code 424: Examination request
- Effect:
- Exam indicator
Your return was referred to the IRS's examination or appeals function.
What code 424 means
Code 424 shows the return was referred to the IRS's Examination or Appeals function and opens examination inventory.
It can also be generated when an underreporter case, a review of income that doesn't match what was reported to the IRS, is referred to Examination.
Like 420, it can lead to a 570 hold if a credit posts while it's open. Code 421 reverses it.
