U.S. District Judge T.S. Ellis imposed the sentence of 47 months in prison on Manafort, 69, during the hearing in Alexandria, Virginia.
Mueller is preparing to submit to U.S. Attorney General William Barr a report on his investigation into whether Trump's campaign conspired with Russian Federation and whether Trump has unlawfully sought to obstruct the probe.
A jury in Alexandria convicted Manafort a year ago on eight counts of tax and bank fraud related to his overseas work advising politicians in Ukraine.
The filing was aimed at persuading a judge to reject Manafort's pleas for leniency at Thursday's sentencing hearing in Alexandria, Virginia.
While prosecutors had not recommended a specific sentence, they had cited federal sentencing guidelines that called for 19-1/2 to 24 years in prison.
Manafort's "misconduct," prosecutors wrote, involved more than $16 million in unreported income (resulting in excess of $6 million in federal taxes owed), upward of $55 million stashed in hidden foreign bank accounts and north of $25 million secured from financial institutions "through lies resulting in a fraud loss of more than $6 million".
Manafort said the "media frenzy" surrounding the case had taken a toll on him, but that he hopes "to turn the notoriety into a positive and show who I really am".
He's paying the price for US crimes he committed while advising pro-Russia politicians in Ukraine and after that, when his cash dried up.
They said "it is Manafort's own criminal actions that have led to these consequences; it can not be blamed on the government or a jury's holding him responsible for his crimes".

Manafort's decisions, Mueller's team said, "were his own and his efforts at misdirection are further proof that he has not accepted responsibility for his criminal conduct".
Also last month, Manafort's lawyers inadvertently revealed in a court filing that their client had shared polling data about the 2016 Trump campaign with Mr Kilimnik.

Prosecutors add that Manafort was not forthcoming with earlier investigators.
They pointed out that Manafort, who suffers from gout, is a first-time offender and said the sentencing guidelines are "clearly disproportionate" for the crimes he committed.
Seth Waxman, a former federal prosecutor and solicitor general, said he was surprised by Ellis' verdict, but that he also anticipates that Manafort will serve more than four years once Berman Jackson issues her sentence.
Manafort contends he is mere collateral damage in special counsel Robert S. Mueller III's investigation into Russian involvement in the 2016 presidential election.
Last fall, Manafort reached a plea agreement with Mueller's team just before he was to go to trial in Washington on a series of other charges, including failing to register as a foreign agent.
Along with Donald Trump Jr and the President's son-in-law Jared Kushner, Manafort was part of a meeting with Russian lawyer Natalia Veselnitskaya in June 2016. "My life, personally and professionally, is in shambles".
