Filed 22 state extensions for one S corporation.

A few through ProSeries.  Some online via website since ProSeries doesn't support. Some only require Federal extension.  Some mail in.  Some require payment but don't have state charter so no clue what to do.  (1) ProSeries needs to support all states, it's 2022, not 1989. (2) States need consistency - took hours to figure this crap out.  Some have income tax, franchise tax, business privilege tax, PTE tax, composite tax, annual filing fee, etc., etc.

Last year shipped this client off to a big firm.  They gave no service so client came back to me.  ProSeries is not designed for this.
