I just sold a vacation home (closed Nov 7) with a $90k profit. My only income is social security (received all year) and spouse part time work with $10k earnings since September. We file jointly and have not paid any tax over the course of the year. Do I need to make a 4th qtr tax payment? From January until September I did not think we would have earned enough to pay taxes. Will this keep us from paying a penalty?
