I had an unexpected large short term capital gain in 2016 from the sale of a stock. As such, I received notification to make estimated payments for 2017. I am currently retired, and all of my income is derived from investments. As such, there is no guarantee that I will have any income to report for 2017, except for dividends. I sincerely doubt that I will have anywhere near the gain I had in 2016. I am just questioning the need to make the estimated payments, and if not made how to determine the potential amount of penalties I may incur if I fail to do so and do exceed the $1000 penalty threshold. Thanks.
