To answer your original question …
I currently happily pay “more” tax as a Scottish top rate tax payer (48%) when I could very easily move to south of the border. it costs me a few thousand a year in extra tax. I didn’t mind the extra, until recently where it seems like it’s being wasted.
I’m not wild about VAT on school fees, I think it should have been phased in to minimise the impact on the children, but we only have 2 more years to go so we’ll suck it up.
However, for various complicated reasons all of my tax and retirement planning relies on the current pension rules. If they change to such an extent that the relief is capped at 30% and the 25% lump sum is no longer tax free, it will affect me to the tune of well over £200k and I won’t be able to afford to retire when I need to.
I have a progressive illness, so there is a clear time component. I won’t be able to just work for longer.
So, being pragmatic, in 2 years once youngest is finished in school I will move abroad. I am lucky that my job will follow me, so I will just chose somewhere nice, but with lower income tax. Or I might go to e.g. Dubai where I could earn more. This will make up for the shortfall for me, but of course will cost the U.K. government who won’t get my tax. And yes, I fully understand that they won’t miss it on an individual level.
I’d rather stay here and pay “a bit” more tax because I have always been proud to be able to contribute. I’ve always paid exactly what I owed, never looked for tax loopholes. But unfortunately my altruism only stretches so far.
