Should I use the tax payment stub for state taxes that says form not final, do not file?

I wouldn't but that's just me.

Other options:

Check your won state's tax wesite:

1) IF you want to actually do a Direct Debit form a checking account, some states have a payment site in their own tax pages taht allow you to do a D.Debit and jsut dump the form.

2)  IF you still want to pay by check in the mail, the state's tax sites usually also have a voucher form you can download and print out as a PDF document.

Why does the voucher have Do Not File on it???

....Well........

a)  Some states allow E-filing before they allow any state forms to be prepared and mailed in on paper...sticking a DO Not File on those forms at that point in time, keeps people form mailing them in before their staff are ready for paper form processing.

b)  You might try downloading a NEW pdf of your tax file and see if it's still printing out that voucher the same way...sometimes TTX updates the forms in an account after-the-fact to take off the Do Not File  (but I can't know if they did so in every/any case)
