The Financial Services Compensation Scheme (FSCS) has confirmed a £60m interim levy for financial advisers and other investment intermediaries.
Firms in this sector will be sent invoices for their share of the levy by the end of March and will have 30 days to pay the invoice or use existing credit facilities to spread the costs of the levy.
Along with the annual levy, it brings the total cost for investment intermediaries to £82m, still below the £100m annual limit for the sub-class.
Investment fund managers have not been hit with an interim levy.
The FSCS said the levy was driven by claims relating to MF Global, Keydata Investments Services Ltd, CF Arch Cru and Wills and Co, as well as other firms.
It added the claims were higher than previously assumed, resulting in a funding deficit in 2011/12, with MF Global claims alone expected to account for almost £27m this year.
In addition, it said it had made more decisions on Keydata claims than previously predicted, with a higher average compensation payment than earlier claims.
The FSCS has a duty to pay compensation claims as they fall due. Funding is necessary to cover the costs of compensation claims until the next levy is raised and becomes available in July.
Mark Neale, FSCS chief executive, said: "Our role is to provide compensation for valid claims as they fall due. This helps to build consumer confidence.
"Unfortunately, the value and volume of claims coming to us is highly unpredictable and the costs, as a result, are higher than previously assumed.
"So, as we advised the industry earlier this year, we have to issue an interim levy to continue meeting our responsibilities. We know this will be unwelcome news and sympathise with firms about the unpredictability of compensation costs. We do everything we can to provide as much certainty as possible."
