Easy to use
I couldn't find what I was looking for on the CRA site and this popped up in my search. I have used it before for Real Estate forms. I didn't know I could use it for CRA forms too.
I love how easy it is to use.

It's a bit soon to rate pdfFiller
It's a bit soon to rate pdfFiller, because I've only had a little bit of time to get familiar with it, and I've never had experience with anything else that has allowed me to edit a pdf file as this s/w has enabled me to.

I signed up originally to utilise this service. Whilst I did not wish to continue with the service (just wouldnt need it again) I did struggle to cancel the service. I sent an email outlining my issue and got the quickest response back and my account fixed and funds returned. Great service if you do require all the time. Easy to use. Highly recommend.

What gives to pdfFiller the edge over its competitors?
pdfFiller is not basically a PDF reader or editor. It’s an all-purpose platform for centralized document management. It enables you to do anything the competitors do and goes beyond that, providing benefits you’d normally get in several tools. With pdfFiller, you get all you may need for setting up effective document workflows.
Simple document management'
No need to download or set up things. Just set up an account, upload your documents, and begin working right away: rearrange, convert, split, annotate, edit, and more you can do to document the way you want. Then, send copies by using email, fax, SMS, or even USPS.
Unparalleled time-efficiency
As opposed to quite a couple of our competitors, we appreciate your time and want you to be as productive as possible. Make templates for the most regularly used documents to avoid retyping data, fill out as much as 1,000 uniform documents at a time, or extract data from forms in bulk.
Extensive library of forms and templates
Need a standardized, fillable form here and now? Discover it in the pdfFiller online library. Or generate a form on your own by basically adding fillable fields to your document. You are able to host or share forms in seconds, enabling anybody to fill them out online from any device.
Very simple e-signing and tax reporting
Due to the integrated signNow functionality, you are able to e-sign documents on the go, collect signatures from a number of people, track the signing progress of a document, set a signing order, etc.
Safety and lots of storage space
We care about the security of the assets and think that storage limits shouldn't distract you from your perform. That’s why pdfFiller allows you to keep your documents safe inside the cloud with limitless storage. On top of that, you’ll be able to protect sensitive information with two-factor authentication and passwords.
