You need a non-electronic way to bill land owners for property taxes. That's it. Physical snail-mail is the de-facto way for the government to legally serve property taxes and other bills to private citizens. Yes we live in 2026 and everyone has email, but there's no legal requirement to give the government your email address, or even have one. You are however, legally required to provide a mailing address for your property tax bill to be sent to.

Sure, by that standard we could probably reduce to weekly or even monthly mail service. It's been suggested since at least 2008 we drop Tuesday mail service as almost nobody sends mail on Saturdays and there's no mail service on Sundays.

Who says anything about e-mail? Government could legislate specific government electronic inboxes, with e-mail and SMS notifications of delivery, as has been happening in several, if not all EU countries.

I haven't got a snail mail from my government for years at this point, nor did I needed to send one that way.

I pay all of my property taxes online.
