The Charity Commission will periodically publish a list of charities in a particular area that have failed to submit their annual accounts to the commission.
On Friday, the commission published a list of 57 charities in the Sefton Council area of Merseyside which it said were not up to date with filing their accounts.
In a statement, the commission, which has an office in the area, said: "From time to time, the commission will give a snapshot of which charities in a particular area are in default."
It said charities could contact the commission if they wished to query their entry on the list.
A commission spokesman said: "This is the first in a number of areas which have been picked as they have below average compliance.
"The commission intends to focus on more areas from time to time to promote compliance with the accounting regulations."
However, he did not say when the next list of non-complaint charities would be published, or which area it would be.
The commission also highlighted the fact that visitors to its website could carry out checks on charities in their own local area, using the register of charities advanced search to filter charities with overdue documents by local authority area.
Its statement said: "If you encounter a charity that is not up to date with its reporting, challenge the trustees and consider carefully before committing to give them financial assistance."
