Rezaian, the US newspaper's Tehran correspondent, was arrested in July 2014 and accused of spying and other crimes against national security.
He is a dual Iranian-American citizen and was tried in four hearings behind closed doors, the last of which was held in August.
"The verdict for this case has been issued," Gholamhossein Mohseni Ejeie, the judiciary's spokesman and deputy chief, was quoted as saying on its official website.
"This verdict can be appealed," he said, suggesting Rezaian had been found guilty.
Ejeie added: "The time for an appeal is not yet over. So the court waits and if it doesn't receive an appeal... the verdict becomes final."
An announcer on state television later quoted Ejeie as saying Rezaian had been "convicted" but no footage of the spokesman making such a remark was aired.
The 39-year-old reporter's lawyer could not immediately be reached for comment.
The treatment and trial of the journalist has drawn condemnation from his family, employer, the US government and press freedom groups.
The Post has called the trial a "sick brew of farce and tragedy" and said it "has been anything but transparent and just".
On Sunday, the US State Department said it was closely monitoring Rezaian's fate and again called for him to be freed.
"We've seen the news reports concerning a verdict in the case of US citizen Jason Rezaian, but have not yet seen any official confirmation or details of a specific verdict from Iranian authorities," said spokesman John Kirby.
"We continue to call for all charges against Jason to be dropped and for him to be immediately released."
Washington Post executive editor Martin Baron said that "this vague and puzzling statement" from the Iranian judiciary "only adds to the injustice" surrounding Rezaian's case.
"It is not clear whether this ruling includes a verdict or a sentence — or even whether its contents have been communicated to Jason or his lawyer," he said.
"If indeed a ruling has been issued and is now being reviewed, this puts on the onus on Iran’s senior leaders to demonstrate the fairness and justice that could only lead to Jason’s exoneration and release," said Baron.
