Does all the following sound correct? In mid-January 2026, I “converted IRA to ROTH (cIRA2ROTH)” in the amount of $330k paying $80k in estimated tax. Note all my IRAs are converted from 401ks and not considered traditional IRAs. There are no after-tax contributions within my IRAs, only in my ROTHs. I will file Married filing Jointly (MFJ), where I am not labeled an HCE for this year, but was last year for 2025. As of my mid-January’s cIRA2ROTH, I know my final tax bracket will be 32%, if I do no more cIRA2ROTHs. Projecting my 2026 W4 withholdings plus the $80k estimated tax, this will be at least 101% of my 2026 total tax bill. Therefore the 90% is Safe Harbor rule for 2026 will protect me from penalty, even if I do additional cIRA2ROTHs before the end of this year. It was also recommended I calculate my maximum estimated tax rate for 2026 then divide this by 4, making four Quarterly payments of this amount (a little tricky since I need to consider Qtrly W2 withholdings, but doable). Provided I pay the estimated tax at the same time of the next cIRA2ROTH at my final estimated tax rate. using Form 2210 Schedule AI as a guideline where I can’t rely on the various MFJ tax brackets levels like I did for the mid-Jan cIRA2ROTH, must do this at my final tax rates will get penalized after the fact (post-15Apr2027) for underpayments the whole year. My main concern is I have made some bad assumptions above where in mid-Jan I needed to pay a higher estimated tax than the 25% I did on the $330K (this was due to the MFJ Tax Bracketing) where all year I will be considered making underpayments (Form2210 AI)
