OK, thanks.
Approximately 1/3 of the $70,000 lump sum (i.e., $23,000), can be attributed to each of the 3 prior years.
So, if in 2016, for example, 85% of my SS benefits were taxable, does this mean that I will have to pay taxes on $20,000 (85% of $23,000) on my 2019 return?
Does if matter if we filed jointly in 2016 and my wife had no SS benefits in that year?
