Thanks @dmertz Im doing research and I have a hypothetical question similar to this situation, I’m hopeful you can help.
let’s say this year I file my normal tax return in march 2025. In early April, I notice that I missed something that increases my tax liability, but my return hasn’t been accepted yet. Since I know I shouldn’t file an amendment until the original return is processed, could I at least pay the amount I know I additionally owe online right away? Would this make it so I don’t have to pay interest - Even tho the date I submit my amendment is after April 15th? Or is the most important thing the IRS looks at the date of filing the amendment to if you owe interest?
