A CP2501 is an early inquiry. The IRS spotted income reported by a third party that does not appear to match your return, and it is asking for clarification.
Unlike a CP2000, a CP2501 does not usually propose a specific tax amount. It shows the item in question and asks you to explain or confirm it.
It sits one step ahead of the CP2000 in the same underreporter process. The notice describes the item, the year, and a date by which a reply is requested.
