There is a small flaw in your poll tax maths Teribus. It assumes that the people who owed it paid it.

The fact is that they didn't - it was an easy tax to avoid. Tax on buildings gets paid - the people may move but the buildings don't.

The problem is that it needs to have more bands so that those with the huge houses in the posh suburbs pay more.

Remarkably the old rateable system was complained about loud and long by the rich - it was one of the few taxes they couldn't avoid.
