Faced with the daunting task of filling in the complete IRS 990 (due to the dissolution of a 501c7 non-profit corporation of which I was the treasurer) I have found that the PDFfiller program is a real godsend -- so much so that I almost regret not having an excuse to continue as a subscriber once the trial-period expires. But I will highly recommend the program to anyone I might know who regularly is faced with filing long or complicated tax forms.

Easy to Use but Not Free
This is a typical program that is easy to use as long as you are familiar with PDF editing programs. They do provide tips when you first begin in case you need them. My only complaint and it is for all these "free" programs, is that there are no free programs. All of them make you sign up with your info for a trial period and if you don't like it you better be sure to cancel before the intro period is up or you will be hit with an annual fee.

It's the best experience on pdf editors, the only thing is that i passed 10 minutes just to find how to change the color of the text, i suggest to modify the icon of the text color for better user experience and as a back-end developer I thank you for the work you are doing, work for your project, believe on it and you will have more success. I hope you share my comment with all your team, this will motivate them to do more effort for pdfFiller. have a nice day, stay positive and good luck.
