One in 11 charities which must file accounts with the Charity Commission is currently late submitting financial information, according to the Commission register.

Just under 61,000 charities have an income over £25,000 and must file annual accounts with the Commission. Of these, 5,334 are listed as in default.

The register lists 6,503 charities with an income over £1m, of which 260 – around one in 25 – are in default. Thirteen of those charities have an income over £10m.

The end of January was the deadline to file information for the majority of charities, which end their financial year in March. The Commission has now updated its register to reflect charities which missed that deadline.

Sam Younger, chief executive of the Commission, said it was “saddening and surprising” to see that a “significant minority” of charities were failing to file accounts despite having ten months to do so.

“Our attitude to charities in default is hardening,” he said. “The Commission will not tolerate charities that demonstrate contempt for the public they are accountable to by failing to meet reporting requirements.”

The largest charity still operating which is not listed as having filed is United Bible Societies, the world’s largest distributor of bibles, which last filed accounts for the period up to December 2011, showing it had an income of £30.95m during that period. The accounts are listed as 103 days overdue, and a spokeswoman for the charity said its accounts had just been filed.

The largest charity in default is the Museums, Libraries and Archives Council, a non-departmental public body which was abolished in 2012 but remains on the register.

Organisations which are no longer operational remain on the register until they have completed a winding up process, which in the case of large charities can take several years.

Several other large organisations which are in default are also no longer operating.
