When I started my apprenticeship as assistant tax adviser in 2016, I used the fax regularly to send stuff to the IRS equivalent. I was also in charge of printing certain thing because the setup for those to come out right was unholy. In the company I am in now, we are pushing for digital solutions but still have a lot of clients with a listed fax number. One of our digital partners had fax: we don’t do that here written in their signature.
