No date has yet been set for the release of the book, with the coming only several months after Mr Johnson announcement was forced from office and amid ongoing speculation that he might harbour ambitions to return to frontline politics.
His wife Carrie Johnson is also believed to be writing a book. Arabella Pike, publishing director at HarperCollins' William Collins imprint, promised a prime ministerial memoir "like no other".
She said: "I look forward to working with Boris Johnson as he writes his account of his time in office during some of the most momentous events the United Kingdom has seen in recent times."
The disgraced former PM's fee is undisclosed, but publishing insiders have suggested he could be paid more than £6m. Other prime ministers who have written memoirs are believed to have gained a hefty six-figure sum for their deals.
Tony Blair reportedly made £4.6m for his memoir A Journey, while David Cameron was reported to have earned £1.5m for his memoir, For The Record.
