I think that the letters pull the date from the return data. If the return won't allow a date in the payment date field past 4/30 without an error, the problem isn't in the letter. It's in the software. However, we had a similar problem last year when the due date was wrong because MD hadn't updated the e-file system due dates. When MD fixed their error, ProSeries could change the date and fix the problem in the software. It was a problem within the e-file programs, not the return software. I'm not sure what the problem is. I'm grasping for solutions along with everyone else. But last year on the filing deadline of 7/15, the software wouldn't allow any e-filing of extensions and the problem was at the Comptroller's office. They fixed it and then ProSeries would allow for the e-filing of extensions. I'm very frustrated with this whole system this year. So if we keep doing the same thing and it isn't working, maybe we should try something else!
