My partner passed away last year , as his estate administrator I am attempting to file his taxes (personal and estate). His employer sent a (2024)1099 Misc form under his name for stocks (listed under Other Income, box 3). I also received a 1099B Supplemental statement for the same amount from the brokerage firm for when I sold the stock (needed to liquidate and transfer funds to daughter's Estate). Aren't the two forms reporting the same income? Wont I be taxed twice for the same funds? Do I need to have his employer correct the 1099 Misc form? Sorry, lots of questions!
If I understand correctly, your partner's employer issued him company stock and reported that as income. You then sold the stock and received a Form1099-B reporting the sale. If the cost basis on the 1099-B is zero, you will need to adjust it so that it is the same amount as the income reported on the Form 1099-B. Brokers typically report a zero cost basis when company stock is involved, requiring it to be adjusted when the sale is reported.
