Vetinari's solution: tax the rat farms.
Be afraid, be very afraid. I think there's some merit to charging maybe a premium for large energy users to cover infrastructure upgrades. But that sort of happens give those costs are meant to be included in our energy bills anyway. CO2 emissions is just greenwashing it. The more alarming part is-
Gen AI will turn classic tax theory upside down and urge a rethink of the old ways of doing things. It may, for instance, usher in the design of a personalized progressive value-added tax, an income tax based on lifetime income, or a real-time market-value-based property tax."
VAT is a pretty regressive tax. Personalising it could imply tracking spending to vary any rate. Obviously that has privacy concerns, not to mention making shopping confusing. UK generally doesn't allow ex-VAT prices to be displayed so people might have to get used to US-style pricing where VAT/sales tax gets added at the checkout. But it could be used to make VAT less regressive by creating VAT bands based on income. Then again, there has been a lot of noise about creating individual carbon allowances that could replace, or more likely supplement VAT.
Tax based on lifetime income seems a bit pointless given income is already taxed, along with additional taxes like capital gains. It sounds like a variation on US proposals to tax assets as a 'wealth tax' and tax unrealised income. Real-time property tax also seems a bit pointless and risky given propert taxes are usually annual charges.
But other than using AI to generate new tax models, it doesn't sound like it really needs AI. Plus it'd need HMRC to spend billions to implement and manage any dynamic taxing models. Like a lot of AI hype, it seems to be a soluton looking for a problem, although I guess an AI might be able to help monitor for tax evasion and fraud.
