Not all states allow electronic estimates especially with clients on extension.

Lacerte will not determine/verify this for you.

Intuit will allow you to set-up electronic estimates payment without Critical Diagnostic. Check all the possible boxes, force dates and amounts -- and even the Letter will change. And then... nothing. Client will need revert to mailing paper vouchers and manual checks. 

Be sure to check the FinTrans Summary in Forms to double check if electronic is possible. All electronic transactions scheduled will appear there. If it does not show Estimates, they're not an available option for that taxpayer.*

(*electronic payment, especially Estimates is fairly "new" for my firm, we tend to not change things until broken. If I am mistaken in my explanation, I beg leniency in your retaliation. I finally had enough of hand crafting out of state vouchers so I am now all in on electronic payments when possible! And I'm all for dropping out of state clients but that's another discussion.)
