Once I figured how to use PDFiller it was great. It worked as I hoped and it served is intent. If the occasion arises again I will definitely use PDFiller. Thanks for your customer service attitude and your expeditious response to my requests and clarification.

I found that PDFfiller allowed me to fill out & print tax forms that were not supported by my tax software.I do wish that your service was bit more straight forward in the pricing. I almost didn't sign up because I felt tricked into using the form thinking it was free. A free form or 2 and I would have signed up 100% no questions. Allowing me to fill it out first then charging me was more like a 50% chance I was going to sign up & pay.

I complete 1099Misc for my office annually. I just discovered your site which is handy as far as anticipated amending and last minute entries. I am having trouble with the How To's of IRS submitting and multiple entries.

You need t tell people that if they enter numbers with commas, the IRS filing process does not work. After lots of time and trial/error, I stumbled across that as the cause of my problems.

Excellent Software and a great price Very good and have used it for years. PDF filler works so well and make it so easy to fill out forms online. It works and the price is very reasonable.

To get the best resolution when printing, you need to signal to your printer how many pixels per inch PPI you want it to print. If you send too few pixels to the printer it will just make pixels up in an effort to fill the page. JPG is destructive to image quality and the more you save over it the worse it gets.
