It was easy to fill out but I had trouble finding information on 'other' in the first section. I didn't quite understand exactly if I was to put "nonprofit organization" on the line.

Not sure yet why the W2 would not send to IRS. the button was not lit up after I completed all of my information into the W2 forms. I doubt that I will be able to afford your product due to it billing annually. Also, the price is too high for my budget. -EPOC Bookings

This is the best PDF program Ive used
This is the best PDF program Ive used. Ive long wanted something to compete with Adobe and this is it. I love the ease of using all features, especially the editing/adding text option. This program is top tier! As a healthcare provider who has to often complete forms for patients, this program exceeds my expectations.

A feature that is critical to my business broke on Friday. I was able to interface and get updates about the fix over the entire weekend and had the problem solved by the dev team before Monday morning. Awesome teamwork from the folks at PDFiller from end to end. Highly recommend.

Immediate refund received
I had thought I had cancelled my subscription so was very surprised to get a notification from PayPal that I had been charged $96. I immediately contacted pdfFiller and the matter was sorted out, and a refund received, within a couple of hours. Friendly and efficient service, with no arguments. Very impressed.
