Mostly good - had a little difficulty when the app decided I could only answer 1 category when I needed to respond to all 5 subcategories of a question. Also, messed with the date - it changed to a different format.

I filled in IRS 990, Schedules A & O but didn't know I was using PDFfiller and when I tried to print I found I was locked out, so I had to subscribe and still have filled our forms that are locked out. Need timely hep in unlocking these documents. Since this experience and subscribing to PDFfiller (annual Suscrition) I have found it works very well. I contract for a Jazz club's 5 venues sites and have to fill out two cities' forms that I found easy to get using PDFfiller. I also became the treasurer of the Jazz Club again and had to bring out IRS 990s up to dat--non-profit. Again fond using PDFfiller to get fillable forms easy, better than going to IRI.gov.

Very easy and intuitive, the learning curve is very small. Tiny differences in the drawing between what you see on the screen and in the printed document.
