  • Companies should plan now to minimise their pension protection levy

    The amount that pension schemes have to pay to the Pension Protection Fund (PPF) for the year 2006/07 may have increased by as much as five times the previous year's levy. Employers who ultimately bear the cost of many pension schemes will need to make plans now to ensure the levy payable for the year 2008/09 is kept to a minimum.
