I have a somewhat messy tax situation for a taxpayer whose father passed away in January of 2021. For 2021, the father had W2 and investment income, along with a trust that has investment income and a vacant land sale after his passing. So, there is a final 1040 filing and a trust return filing to be done for 2021. Seems fairly straightforward so far, as no distributions were made and the trust will owe some taxes. On the father's original W2, there were also some company stock included in Box 1 wages, with federal and state taxes withheld. To put some figures to it, the original 2021 W2 showed roughly $400k in wages, $90k in federal tax withholdings, and $20k in state withholdings. That $400k was roughly $100k in salary and $300k related to company stock. After getting the original W2, it was determined that the father's stock plan (the taxpayer calls it stock options, and I'm trying to confirm it wasn't RSU/Grants instead) had no beneficiary and had to go through probate and, therefore, an estate tax filing is also required for capturing that income. So, a 'corrected' W2 was issued that shows just the $100k of salary, however it didn't correct the withholdings and kept the full $90k federal tax withholdings under the taxpayer's SSN which will lead to a large refund if that is entered on his final 1040 filing. Along with the corrected W2, there is a 1099-B under the estate tax ID, now, that shows the other roughly $300k of short-term capital gains related to the stock options that had originally been shown on the W2 form. That 1099-B shows the same date for the 'acquire' and 'sold' date of the stock, which is November 18, 2021, so it's a STCG as shown on the 1099. So, there are now 3 returns to be filed (1040, trust, estate) and some things I'd like any thoughts on:
1. For filing the father's final return, it seems like the corrected W2 did not properly account/adjust for the tax withholdings (ie- W2 Box 2 for federal withheld and Box 17 for state withheld) that were related to the stock that is being reported on the estate return, and if I file using that W-2c information then there will be a large 1040 refund, but a large estate tax balance owed (plus penalty/interest). I have the deceased father's final paystub that shows about $20k of that federal withholding was taken from his paychecks, which would leave about $70k that could be related to the stock income to be reported on the estate return. Should another W-2c be requested to correct the federal/state withholdings? If so, part of me thinks the returns should be filed now using the withholdings as they should have been reflected on the 1040/estate returns ($20k on 1040 and $70k on estate), as it took over 6 months for this corrected W-2c to be received.
2. If the stock received were stock options, wouldn't those ordinarily not be run through your paycheck? It seems like only RSUs or grants would be run through the employee's W2, with withholdings taken out? If these were truly stock grants/RSUs, instead of stock options, should they possibly have remained on the W2 as income reported on the taxpayer's final return, and then just the small capital gain/loss would be reported on the estate return when those were later sold in November 2021?
3. The vacant land that the father owned and that the trust later sold was purchased one month before the father passed away. I'm not sure if there is a step-up/down in basis, but absent any other figure would it be reasonable to just use the purchase price as cost-basis for the land sold by the trust, since it was purchased so close to the date of passing?
Thoughts on any other considerations here? Thanks
