I know that most IRS forms are free and can be saved to my files, however sometimes trying to download the forms is difficult to do. PD Filler is much more user friendly and easy to follow.

At first, I didn't understand what I needed to do first. I filled out the form I pulled up and then submitted it, but was sent to a page to choose which plan I wanted. When I realized I needed to choose a plan, I chose one, but then I had to fill out the form all over again! Then I submitted it, but the form again, but it wouldn't appear on my list of filled forms. My list only lhad a previous form from 7/15/2015. I chatted with a representative and she helped me get my second version on my list. This rep was extremely patient and nice, and did all she could to help me. I'm very happy I spoke with her.

So far it has been frustrating ( just because I am not tech savvy) I am just trying to reprint a pay stub that I have lost from a former employer and I just keep running into problems. However after watching a video I figured it out without a problem. Customer service is A1.

What do you like best?
The program is very quick and easy to use. Uploads your documents very fast. You can type or alternate any pdf or word file. It saves it in no time. You can go back and look at any file you have uploaded. Everything is saved. I also love the fact I can use it on my phone as well through the app. It is extremely convenient. I can fill out new vendors forms very quick which saves me time.
What do you dislike?
I haven't come up with any problems for as long as I have used it...over 2 years now.
What problems are you solving with the product? What benefits have you realized?
It saves me a lot of time. It is a very convenient and fast way to fill out forms or alternate them. Adding a signature on any form is so easy to do through pdffiller. I don't have to print the form, chase my husband to sign, scan it and then email it. Imagine just uploading your form, adding the signature which is already saved and you're DONE :D

Excellent and modern convenience I used PDF filler for just about everything- I am constantly needing to fax things and being able to do it digitally and get confirmation that it was received is great. I also use the form filler to easily electronically sign and send documents back and forth! Nothing, to be honest, the platform is super user-friendly, the cost is reasonable and the product always works!

Work & covid has been occupying me so much that I forgot to cancel my free trial. I sent in a ticket and spoke to a staff named Phoebe. She replied extremely fast, understood my situation and proceeded to help me with my refund. I am very satisfied with the outcome & would recommend pdfFiller to everyone as their customer support is top notch.

Great services with an excellent customer care policy I enjoyed great services provided by pdfFiller through an annual plan. I used their service in all my dealings with pdf documents. Then for professional reasons, I had to cancel my subscription, and pdfFiller team was extremely kind in offering me a full refund of my subscription fee. Just after 3 minutes of sending them a message, they responded back explaining the details of my refund process. That is what I call a great customer care and professionalism! Once again thanks a lot!

I received pdf's from an online class that the asked me to print out, complete, scan back. I just did not want to print mostly but the entire process ... you know. pdfFiller helped out a lot, especially with the symbols (might want to add music notes).
