I have completed my 1040 and realize I owe money (<$500) (due to passive income) to the IRS, however, I will not have completed all the other forms, ie my 5471 in time for the April17th deadline. However, I will file by June 15th. Which payment voucher should I include with my check payment that I plan to mail today. I know I can send the check in June with my return but want to avoid interest charges. A 1040V or a 1040ES voucher. I assume a 2017 1040ES or is there something specific for overseas filers that I am unaware of.
