It's actually very simple.
Once you eliminate a local sales tax as bonkers unworkable (which probably makes it the #1 option in official circles) you are left with three options:
- No tax whatsoever and people can just pay for whatever services they use directly.
- Tax people
- Tax property
Of the remaining non-bonkers options, taxing property is easiest because - apart from a few rare exceptions - houses don't move around the country like people.
Assuming you have a "register of people" (we don't) then given how many people move around in chaotic fashion, you will simply end up with more and more uncollected years and people. It would need to be a system ten times as large as the Universal Credit system, and capable of working in real time.
The most efficient and fairest system is the one no one will ever vote for, and that is a base figure for the property with a modifier based on occupancy. However that will be spun as a "tax on children" at one end, and a "tax on granny" at the other end. With the obvious weakness that we know people "move" children around for the best school anyway.
However this debate isn't really going to progress until more people learn what tax is and how it works and why it's needed. Because the last few years have seen a concerted - and surprisingly effective - campaign in the media to pretend that a world with no taxes is within our grasp. All we need to do is be brave enough to hope to dare to imagine
Go on - it's easy if you try
