2644C Letter from IRS for 2025

[mknagorka]

I have 3 notification letter from the IRS. The first was a 'IRS Notice CP05'. The second notice was 'IRS LTR 2645C'. The most recent was 'IRS LTR 2644C'.  Each notice/letter informs me that there is nothing I need to do, but states that they need an additional 60 days to complete their response.

The most recent letter states that they are  waiting for my tax account information to be available on 'their computer system'.

Can anyone tell me what tax account information they are waiting on? Also why is it not on their system?

They are  probably verifying income or withholding. Possibly your employer or broker didn’t send the required forms.

If you register through ID.Me or already have an account, you may be able to review your 2025 account transcript to see what the IRS has 

ID.ME 

or you may want to contact the Taxpayer Advocate Service to see if they can speed things up,
