Installment agreement with new balance
On 6/10 I filed an amendment for 2024 which resulted in an extra $4100 (I know there will be additional penalties and interest). The amendment is still processing and I plan to set up an installment agreement for about 12 months. When I was reviving my transcript I saw a small 1099 that I missed which will result in about $400 additional taxes.
I know that I will need to file a second amendment when the first finishes processing but my question is, what happens to my installment agreement? I know that any new balance will cause it to default but will I have the opportunity to modify my current agreement before that happens?
I know a cp523 will eventually be sent out if I don’t pay the balance, but will I have time to modify the agreement before this letter is generated?
