How would you change the UK tax system?

In order to raise further tax funds, I would propose further taxes to be imposed upon the poor, that is to say, we should institute a regressive taxation system. Increasing taxes on rich people will only result in their flight from the country and acquiring residency in a tax haven. Any tax money raised from the rich, no matter how small is beneficial for the nation. We are better having the rich paying a small sum of tax than no taxes whatsoever. The poor however lack the flexibility of the rich and are less able to avoid paying taxes through legal methods such as using loop holes through clever accounting and moving country. Therefore we could reap a far greater sum of taxation by milking the poor than increasing taxes on the rich.

Flat tax.
Lower VAT.

Get more people spending.

sounds like a plan dr evil

assuming we had no more debt/debt interest:

flat rate of tax, 10%
OR, abolish the income tax and replace it with a national VAT
either one or the other

also, I'd turn council tax into a (very low) percentage of earnings, opposed to a fixed rate depending on the value of your property

and no more death (inheritance) tax

People earning the average wage (currently 24,000 outside London) should not pay more than a fifth of their in Income in tax.
Taxes should be lower in London, how are graduates with out rich parents suppose to be socially mobile if they cant afford to take jobs in London

Do you know how much VAT would have to rise to make up for lost Income tax ? also VAT sales are unstable.
You would turn a council tax which is a wealth tax into a income tax ? Income taxes are more unstable than wealth taxes and economists generally prefer wealth taxes over income taxes, as income tax is easy for rich people to evade

but why would you take a job in the most expensive city in the UK and arguably in the whole of europe if you can't afford to live there? how is that playing it safe? there's a reason it costs so much to live there - because people who live there are normally richer and can afford the higher costs

I'd have very low spending if I were in charge, e.g. I'd deregulate most publicly owned institutions, e.g. the department of education, the department for health, the department for culture, the department for agriculture, social housing, pensions, etc, so VAT wouldn't need to be too much for it to replace an income tax seeing as so much would be saved through lower taxes. and in terms of local council funding, I still disagree with the ethics of having a person who happens to have a large house but happens to earn little being made to pay a lot of money simply because of what he inherited or received from something like the lottery (e.g. not from direct work)

50% of all graduate jobs are in London.

Its where all the graduate jobs are and many of the high paying middle class jobs(although the trainee salary is quite low) ie trainee barristers get something like 12,000-20,000 a year. However do that for 4-5 years and you can comfortable join the middle class and earn over £40,000. If however you have no resources you will turn down that job and accept a job in another part of the country that pays £18,000 with little chance of earning over £30,000

By deregulate you mean cut ?
Income Tax is about 152 billion so you have to cut about 20% of all spending
National Insurance is about 100 billion, a further 10% cut

Countries like Norway and Holland have wealth taxes on all assets and I think generally they are a good way to tackle inequality in society. So much of income is hard to follow and gets disguised as all sorts. I sympathise with people who inherited a large house, but at there are many things you can do to reduce your inheritance tax, the main people who pay wealth taxes are the wealthy.
