Thank you, baldietax. I appreciate your detailed reply and will continue to work on the details of the calculation.
I'm also in VA, so thank you for that tip about how the state breaks down the year. I did not know that.
Coincidently, I was talking with my wife about this yesterday and we've decided to do the same as you from now on and make quarterly tax payments of 100% of our prior year's total tax owed.
