Roth Conversion Safe Harbor Rule

The safe harbor rule in tax terms allows taxpayers to avoid penalties for underpayment if they meet certain payment criteria, such as:

 

  • paying at least 90% of their current year's tax
  • paying 100% (or 110% for high earners) of the previous year's tax liability

It looks like I fall under the second criteria  (I paid  100% of my 2024 withholding thru my ex-employer and got a refund at tax time).

 

Just wondering why TurboTax assessed a  penalty fee  for tax year 2025?  Though I already instruct TurboTax to let IRS calculate the penalty fee as instructed by a Level 15 community member.
