Whatever you do, don't put your money in a pension fund.
In 1998 my private pension fund with Standard Life was worth £255.000.
Gordon Brown removed the tax relief on dividends for pension funds in 2002/3.
In 2005, my fund was worth £187.000. I bought a fixed rate annuity with the money in that year and would advise anyone thinking of the future to remember Gordon Brown and his successors will always look at pension funds when they are strapped for Treasury cash. Learn from history.
Invest in property to let, here or elsewhere in the world. Buy some gold. Invest in nuclear and recycling companies.
Get an accountant, pay your taxes and retire as soon as you can afford it.
If you feel that being a parasite, and not paying the tax you are obliged to pay, is an uplifting and moral stance, then I hope I never have to fly with you in the future.
Good luck.
