Prince Harry and his wife Meghan have reportedly been working one hour a week at their Archewell Foundation

DailyMail.com, which obtained the public documents, said Harry, 38, and Meghan, 41, "only worked one hour each a week at the foundation, thus,

52 hours a year".

The outlet added the 990 tax return, which it said appeared on the IRS'

website, shows the foundation - named after the Sussexes' three-year-old son Archie - gave out $3,096,319 in grants, and raised "less than $4,500 in public donations".

The foundation is apparently "mostly propped up by two wealthy philanthropists who contributed a combined $13 million", according to the Mail's analysis of the documents.

Papers were also said to show the charity spent $163,085 on salaries - and while Harry and Meghan did not take a wage, its CEO James Holt has apparently received a $59,846 salary and $3,832 in other benefits.

There are reportedly two other salaries on the tax return - $40,867 for "program service" and $22,811 for "management and general expenses", suggesting the charity has three paid staff.

It's been widely reported 16 employees have left the overall Archewell brand - a mix of non-profit and for-profit business including Archewell Productions and Archewell Audio.

The Mail said Harry and Meghan, who also have 21-month-old daughter Lilibet, dec lare in their tax filing Archewell's key mission is to "uplift" and "unite" communities "one act of compassion at a time".

They are said to have added in the documents: "Archewell Foundation believes that compassion is the defining cultural force of thee 21st century and, through its work, Archewell Foundation supports a growing community of partner organisations fuelling systemic cultural change.

"Archewell Foundation listens to people and their communities, helps them tell their stories, puts real action behind its words, and spotlights a new generation of leadership."

Harry and Meghan's foundation impact report released in January said it helped pay for 12.66 million Covid vaccinations globally while working with anti-poverty charity Global Citizen.

Funds were also given to charities supporting refugees from Afghanistan and Ukraine.
