It looks like I'm starting a tax return, but I only want to pay estimated quarterly tax at this point. How do I do that?
Go to this IRS website for payment options. Indicate that you want to use Form 1040-ES for tax year 2016 - https://www.irs.gov/payments
The fourth quarter 2016 payment has to be paid on or before January 17, 2017.
