A year ago I sent out a simple questionnaire: 

(1) Do you want your tax return on paper, or electronically in the portal only (it's automatic for the portal) or both.

(2) Do you want your supporting documents returned, or electronically in the portal only (I combine all into one organized file and it's automatic in the portal), and

(3) Do you want your estimated and/or payment due vouchers on paper, in the portal or both.

I got less than 5% of the people respond to the questionnaire.  So asking them how they plan on paying would be a waste of time.
