The Archewell foundation has been deemed “delinquent” by a US charity registry. 

A charitable foundation set up by the Duke and Duchess of Sussex is at risk of being suspended due to a tax issue. 

California’s Registry of Charities and Fundraisers has branded the Archewell foundation as “delinquent” for failing to submit annual records.

The Daily Express has reported that a delinquency notice letter was sent to the charity on May 3 saying the foundation is "listed as delinquent" for "failing to submit required annual report(s) and/or renewal fees".

An organisation listed as delinquent is banned from "soliciting or disbursing charitable funds" and its registration may be "suspended or revoked".  

The newspaper claims a physical cheque was sent by Archewell Foundation as part of the filing to the California Attorney General’s Office and a new one has been sent to resolve the issue.

The letter from California’s Registry of Charities and Fundraisers is reported to have said: "An organisation that is listed as delinquent is not in good standing and is prohibited from engaging in conduct for which registration is required, including soliciting or disbursing charitable funds. The organisation may also be subject to penalties and its registration may be suspended or revoked by the Registry.

"Once you submit the delinquent record(s), you will be notified of the amount of any late fees that are owed."

The Press Association (PA) has said the foundation believes its tax filings were submitted on time and a cheque was sent and it was only made aware of any issue when the delinquency notice was published. The PA claim the foundation expect the issue to be resolved within seven business days.
