I paid top band tax in the UK for 22 years and paying tax here for plenty of things i never used like education etc I'm pretty sure it will all balance out in an accountant gods eyes.
Like I said if it really bothers you that, as it now seems, when you are going to inherit your mum's house, you will have to pay tax or do something about it.
I'm in exactly the same boat: My mum paid 13k their London terraced house, it's now worth 400k+. So what i have are the options to pay professionals to advise me how to cheat the tax system or lose the money.
If i really want to i can tell my mum to sell it to my sister and her charge her rent to live there thus avoiding IHT, if they do it properly, but i know the laws are changing on this, never mind I find it morally bankrupt and a fairly repugnant idea.
also as a top rate taxpayer in the UK for 22 years, i probably ended up personally paying for my own schooling and one of your family members twice over so yeah, you can admire me if you really want.
Now I pay tax to a country where to be fair I've received literally nothing tangible yet except a strong decent economy and society and a stable country into which i can raise a family if I chose. Sweden not having Inheritance tax will be irrelevant to me because ill die a pauper for sure. You should probably attack me on the angle that Ill never pay back to Sweden what ill take out in the long run.
I really don't get the whole, "i must get what i put back in" mentality with taxation. It always seems to be the ones with the least that complain the loudest too.
