Why forms create friction

People often know they need to do something, but the form names make everything feel more technical than it really is. A forms library lowers that friction.

How to use it

Start with the form itself, then move to the related deadline or tax-help page so the form becomes part of a clear action sequence instead of one more confusing acronym.
