@baldietax Thank you for a very thorough answer.
I believe you mean that to avoid a penalty, you must pay at least the smaller of :
1) 100% of your 2024 tax (110% if AGI > 150k or 75 if filing MFS), or
2) 90% of your 2025 tax
Correct?
Re the AI method. you said :
For the AI method you will need to calculate your AGI, withholding, Qualified Divs, LTCG etc by quarter (not even quarters tho - 3/31, 5/31, 8/31, 12/31) and that will show the uneven income in those buckets and that the estimated tax in Q4 was not late.
This seems very complex. Is there guidance on how to do that?
Thank you
