Perhaps a follow up as I owe an Underpayment despite my seasonal income which happens in Q4 and flat overall income 2022 vs 2023 - yet I still owe the underpayment penalty (first time owing this despite using TT for 6 years with nearly identical income / seasonality).
More specifically, when using the annualization method, what exactly impacts the penalty? The options are:
1. AGI?
2. itemized deductions on Schedule A
3. Net Capital Gains
4. Deductions on Qualified Business Income
I've never had this issue in the past and the tax rules appear to be similar (I am getting a refund, as per past) so this seems like a TT issue (one of many it seems this year, doh!)
