some forms are not as well created. would be nice to be able to tab between fields. or when clicking in fields that should all be within the same horizontal line it would be nice if they automatically lined up rather than having to be moved like individual text boxes.

Some of the fill ins didn't exactly fill in right, but this was my first time using PDF Filler, so maybe it is just part of the learning curve for me. Thanks.

This program is very useful for filling out tax forms. Although my returns are not complicated, getting the credit that I am due for foreign taxes is too much for tax programs like HR Block and too much for most accountants. I have returned to my old habit of doing my returns manually. This PDFfiller program makes it feasible.

I am happy with the selection of forms, but it could be easier to locate forms I need to complete. Also, your connection is pretty slow. I thought it was my internet the first couple of times, but the connectivity only takes eons when trying to access my docs on your site.
