CP23

[daisy6060]

I received a CP23 saying that my tax return was changed to match their record of payments made.  They say I owe $1337.25 which makes no sense.  The payment forms were printed to pay $954 and that is what I have paid twice now.  They say I should be paying $986.  A penalty of $128 was listed on Line 38 on my return and a different total was listed.  However, I used the forms printed by you for my quarterly payments.  Why do they say that I owe the above amount that must be paid by June 23?  What is the penalty for and why are the payment amounts different?  Because of illnesses and surgeries, I forgot to send in my January 2025 payment for 2023 taxes.  However, I did send that payment of $626 in April 2025 when I realized my mistake.  I don't know if that figures in in any way.  I believe the calculations must be a mistake and I do not understand why I should owe what they say, which they say I must pay immediately.  Please help me!

How did you send in the payments?  Did you send them in with a 1040V voucher?  If you used a 1040ES slip that was for quarterly estimated payments for NEXT year 2025 so it didn't get applied to the 2024 tax due.  The current tax due should be 1 payment due by April 15 on the 1040-V.   

You should look up your IRS account and see what year they applied all your payments to, like the one you paid in Jan 2025.   Probably call the IRS to straighten it all out.
