Good experience but unfortunately, I don't need this product at the moment so I will not be renewing my subscription. If I decide to work on taxes in the coming year, I will subscribe.

It served my purposes It served my purposes. There were a few instances where it would not properly let me check a box. Also, inputting dates, did not always work as expected. I was not always able to manually type in a date. It forced me to use the calendar. Sometimes. It's a good tool.

Great services with an excellent customer care policy I enjoyed great services provided by pdfFiller through an annual plan. I used their service in all my dealings with pdf documents. Then for professional reasons, I had to cancel my subscription, and pdfFiller team was extremely kind in offering me a full refund of my subscription fee. Just after 3 minutes of sending them a message, they responded back explaining the details of my refund process. That is what I call a great customer care and professionalism! Once again thanks a lot!
