I was happy to know I could use a blank form to enter my new figures when I had to file an amended form for both the Federal and State Taxes for 2014. Thank you.
Just what I was looking for. Liked the smart software that figured out what fill-ins of IRS forms were in teh wrong spatial location in a box and which ones needed to be copied to later pages.
Needed a pdf file filled in online
Needed a pdf file filled in online, that in and of itself was not the issue. The issue was not being able to recreate the form in that most environments you would need to build the form from scratch. PDFfiller allowed me to upload the form and use their platform to publish it to the public. May I add how quick and easy it was. Saved a ton of time which I don't have.
Saves so much time
I like this software because it is so easy to use. It saved me time and allowed me to quickly complete the necessary document
The only con I have with this software was that when printed it did not print all of the words typed in
My expectations were actually exceeded.
At first, I was overwhelmed by the many functionalities of the site but in a few minutes I got a hang of it. It's actually easy to use and quite handy to say the least. Well done!
