By taking income from a pension fund, together with any charges, your client is reducing the value of their pension fund and potential for future growth - particularly if they take high levels of income and/or investment returns are poor. The value of the fund could fall below the amount originally placed in drawdown and could even run out sooner than illustrated.
Taking high income and/or lump sums may mean your client will pay more tax, and could cause them to enter a higher tax bracket.
Tax treatments are subject to change and depend on individual client circumstances.
Investments can fall in value as well as rise and clients could get back less than they invest.
