Taxes? You fill in the form in on your computer and can file it digitally. And if you print it it‘s encoded in a format similar to QR codes.
Tax offices are fully digital since at least 10 years. If you file with paper it‘s scanned and destroyed. Your local tax office receives all the documents digitally. Of course this could vary by canton.
What they send out (and yes, in the canton of Zürich) is two A3 pages (printed on both sides) a form informing you how to extend sending it in and, most ironically, an A4 page informing, why they send out less paperwork
It's right in front of me. So feel free to prove me wrong.
You should check your envelope again. If you did your taxes online in the past you don’t even have to snail mail the receipts anymore, they accept digital copies/photographs now.
In backward Wallis, I've been receiving a single folded A3 page for at least 5 years. And since last year, I could even snapshot the substantiating documents with my mobile and attach them to my digital tax form if I wanted to.
