I got confused a couple of times when using PDFfiller, but their customer support was outstanding; they immediately responded and were very helpful. PDFfiller is a solid solution for filling out yearly tax paperwork on my Mac. I'll be using it every year now.

I like the online webpage. However, I have trouble using the app. It doesn't have my saved signatures and it won't link to my OneDrive (Office 365) properly.

needed to print out applications, employment verifications and a background questionaiire that required it be typed, printed out and sent via US mail. Most online PDF's will not supply editing capabilities. Thanks PDFillier!

desde un inicio debería estar la indicación de que la aplicación es de pago para contemplarlo, en cuanto el funcionamiento es excelente, solo tengo duda acerca de la leyenda de que solo 5 documentos... al día al mes o a que se refieren? agradezco de antemano su atención.

So Easy to Use Anybody Could Do It I have had a great experience with this program so far it has eliminated my need for some of the other programs I have tried which ultimately has saved a lot of money while also making my job a little easier. PDFiller is so easy to use that you anybody can do it. It walks you through everything but you may not even need to do that its very clear and easy to navigate. This program also has saved me so much time and money on other options in which you would have to get more than one program to accomplish what just this one program does. Once in a while I have to exit out of it because it freezes up, but I'm always able to go right back into it without having to wait.

Well I am finding this to be quite convenient and plus having all types of forms, but since most things come in PDF I am loving it for my small business, I can duplicate the state tax for for each company and only fill in the "seller" info and that is so time saving! I think I am going to absolutely love this, its my first day here and already feel super pleased!
