He earned 46,899 pounds in rent on the London family home, the first such papers released by a British prime minister revealed on Saturday.
The papers showed he inherited 300,000 pounds when his father, Ian Cameron died, and the following year was given two payments of 100,000 pounds by his mother to balance out the legacy.
Cameron announced a new task force to investigate tax-dodging allegations.
Also on Saturday, the prime minister admitted he could have better handled the row over his financial affairs.
The revelations came after a week of questions and successive statements over whether Cameron had owned and sold units in an offshore fund run by his father.
Details of the Blairmore Holdings fund had been contained in a leak of 11 million documents, the ‘Panama Papers’, belonging to Panamanian law firm Mossack Fonseca.
They revealed Ian Cameron had been a client of Mossack Fonseca when establishing the fund for investors.
