For businesses to function properly, they normally need access to some level of cash in the bank.
Although this spare cash may bring some level of comfort, it is possible that it may just sit there dormant, not really achieving anything for either you or your business. In fact over time, it could even become affected by inflation.
A corporate investment strategy could be of use in this scenario. Rather than being left in an account with little prospect for growth, such a strategy could help the money work better for the business.
Keeping your surplus company cash on deposit over the last few years will have meant the capital is unlikely to have grown with inflation. The interest you received would probably also have been low. It is easy to forget the damaging effects of inflation. While it does not reduce the monetary value of your capital, it reduces the real value, eroding the spending power of your money in the future. The small amount of interest you receive is also likely to be subject to Corporation Tax!
A possible solution for your company is to look to invest the money held on deposit over the medium to long term. Your investment should have the potential of providing a better return than a deposit account, not only to keep pace with but to beat inflation, and over the medium to long term aim to provide superior investment returns. Secondly, the investment should be structured so that Corporation Tax is only payable on encashment of units and not annually on any increase in value.
