Living in Jersey I suppose I should have something to add to this.
One of the deciding factors in me leaving the UK was taxation. Pretty much the only thing that isn't taxed is the air... or not, as I'm sure some of the taxation goes towards researching cleaner fuels and encouraging the manufacturing industries to lower their CO2 emissions.
By the time I left the UK (2003) I was paying over a third of my wage in tax plus the 'congestion' charge in London was about to be extended to where it sits today. Don't even get me started on that one! Why couldn't the government just be honest and call it the London Toll? How could it be a congestion charge (tax) when any vehicle which emits less than 100g/km CO2 is exempt (plus others)? Even 'green' cars cause traffic jams. And what happens when more and more vehicles drop below this threshold which is more likely year-on-year.
The tax on fuel is obviously out of control as well. Motorists are always hit the hardest. They operate a much fairer system here where the road tax is included in the cost of the fuel. If you drive more yearly miles or an uneconomical vehicle (
) then you pay more. It gives you the choice plus fuel tax is much lower here, diesel is about £1.19 a litre at the moment and petrol about £1.25 (including tax remember).
But Jersey is outside of the EU and Euro Zone - see you can exist without it. OK, we're in a slightly unusual position in that the offshore finance industry has made it's home here due to the less restrictive regulations and 0% tax they enjoy. The overheads are also lower here which means that the supporting infrastructure is where the tax is made and that is quite extensive.
Tax here is much lower than the UK; you don't pay anything on your first £19K (dependent on circumstances like marriage, kids, etc) and then it's a flat 20% on anything above it. VAT, or GST as we call it, is 5% on any goods over £250. But, and it's quite a big 'but', the cost of living is generally higher and property is expensive, I think the average 3 bedroom house is now rated at £600K+ and that won't be a great one!
So to not cut a very long story short, I pay a fraction of what I did in the UK and have a better environment and general standard of living (due to my tax allowances and reductions I currently only pay 2%). Get out while you can, it's only going to get worse... and the best thing? It's not even your fault and you still have to pay for it all! Brutal.
