mistycoven: Your state/country changed their laws to require digital stores to collect tax, I would presume. Or your state/country always required it and GOG simply wasn't in compliance with their laws. You could try googling (your state name) digital tax for more information.

A tax on digital media like movies and audiobooks could be added to your paid subscriptions as a way to support public transit across the state, at least that's what members of New York's Assembly Majority are proposing.
...
Other media or "digital product" that is "electronically or digitally delivered, streamed or accessed" would also be subject according to the Assembly's proposal. Cable and satellite television as well as newspapers or periodicals would be excluded.
mistycoven: Seems like this is meant to cover public transport.
Public transport is basically a black hole for money to disappear into in this place; every year they cry not enough money, cannot get self funded, much less in budget and service is only getting worse. No surprise though that the public transport system is the excuse given.
Thank you for the response, and apologies for the rant above.
