My husband and wife elderly clients both died in 2018. I have always prepared MFJ returns for them in the past, but the representatives for both estates want a MFS return prepared for 2018 because different people will be entitled to the refunds. (This was a second marriage for both.) They also sold their house in 2018 before they died with a gain of less than $250,000. The 1099-S was issued in the husband's name for the full amount of the sale price. If I put the full amount on the husband's MFS return (so that there will be no matching problem with the IRS), there will be no tax due since the gain is less than $250,000. I'm not sure if this is the proper way to handle this situation and if the husband's estate might complain that the entire amount is on his return (even though there is no tax consequence.) Do you know how this should properly be handled?
