My vote is for higher taxes on things that are bad for society as a whole, ie things that in the long run cause society harm, or drive inefficiency. So, a few ideas that hopefully make society healthier, cause behaviour changes to be more environmentally friendly and efficient.
Increase fuel duty, starting with the reinstatement of the 5p / litre cut, another 5p a year later, then increase per inflation minimum (we have just about the cheapest petrol in western europe).
Road distance travelled tax, applying to all powered vehicles that are registered for use on public rosds; 2p/mlie for the first 10k miles, 3p/mile thereafter.
Double Air Passenger Duty, for domestic flights and Band A (up to 2000 miles)
Double alcohol duty for off sales (I say this as a confirmed drinker) - the price of booze at the supermarket is frankly ridiculously cheap and has risen far less than inflation over the past three decades. (This would add £2.70 to a typical bottle of wine, 40p to a typical 500ml bottle of beer)
Full VAT rate on all fossil fuels where it is not charged already (yes including gas / oil for domestic and industrial consumption)
A ‘fat tax’ - same as the sugar tax on fizzy drinks but on all processed food products with high levels of sugar or fat, with higher tax payments for products higher in sugar or fat (in the same way alcohol duty is progressive).
A ‘takeaway’ tax charge of 10% on top of VAT and the fat tax for every takeway hot fast food order.
Legalise cannabis and have it charged at similar duty levels as tobacco + VAT
Cash tax; 1% on every cash deposit / withdrawl from bank accounts
Crayola tax - additional 10% income tax applies to any individual making suggestions on these pages that includes drawing lines on a map
I expect some of this will have pitfalls that I haven’t considered, and much will be controversial. It is almost all tax on spending rather than incime, but hey ho. But then it’s my opinon!
