Are taxes that were withheld from my 1099R (RMD Distribution) treated as being withheld evenly throughout the year? In my case I took my RMD in late December and had custodian withhold taxes at that time. Until I took the RMD distribution I never really had much income that would trigger estimated tax payments during the year.
I plan on using the annualized income form to support that I actually had no taxable income (after deductions) until the 4th quarter. I'm I correct in thinking that the withheld taxes in December via my RMD distribution (which would cover an amount equal to or more than my actual tax) wouldn't create a "penalty" for underpayment during the year?
