But prosecutors alleged he had used his wife and son to collect more than £2.6 million in illicit funds.
Mr Bo denied taking payments from Tang Xiaolin, the general manager of an international development corporation in the north-eastern city of Dalian, where he once held key posts.
However, he admitted that he had previously told party investigators that he had accepted the payments.
"The matter of me taking money on three occasions does not exist," Mr Bo claimed.
"During my investigation by the Central Disciplinary Commission, I once admitted to this against my will ... however, at the time, my mind was a total blank."
Mr Bo's wife Gu Kailai confessed to killing businessman Neil Heywood and was handed a suspended death sentence last year.
His aide Wang Lijun was sentenced to 15 years' imprisonment for helping Ms Gu cover up Mr Heywood's murder.
