I'm kind of like Lisa, except I give ALL my clients that owe the voucher. Never had a client request to have an automatic payment come out, In fact it took years to talk most of them into using Direct Deposit of their refunds.

Other then the (someday) IRS stopping taking checks for payments, I have no problem with using the mail to make the payments. I seriously can not recall any instances in 45 years of doing taxes where a client complained that the IRS didn't get their payment because it got lost in the mail.

I know I do have some that use the voucher for the amount and make their payments through one of the online methods, and that's great. I just don't want to be responsible for making sure it happens for them.
