I know that the Motor Tax website has been pushing people towards electronic correspondence for some time, but it has always been possible to complete a transaction without giving an email address. I'm taxing Mrs D's car at the moment and it now looks like it is obligatory.

Anyone know when that happened? I taxed a couple of cars at the beginning of March and I don't recall being obliged to provide an email address.

I work in IT, so I tend to be a bit conscious of privacy, data security, EU GDPR, etc. and prefer to not provide more Personally Identifiable Information to anyone than is absolutely necessary. They already have name and address information for mailing the disc, etc. I don't see anywhere to explicitly consent to providing it to them. Taxing online has been a great service, but I'll revert to going to the tax office, or doing it by post in the current situation, if necessary.
