A tournament from the end of November to the end of December was "the most viable period" for the World Cup, the taskforce decided, according to a FIFA statement.
A source later told AFP that the dates proposed would see the tournament begin on November 26 with the final held on December 23.
A final decision will be made by the FIFA executive committee at their meeting in Zurich, Switzerland, on March 19 and looks likely to be approved despite Europe's top clubs stressing their opposition.
"There is one solution, November-December," said FIFA general secretary Jerome Valcke after a meeting of the taskforce in Doha.
Valcke said the group touched on "all the options", including considering holding the World Cup in January and February 2023.
"It is clear there are pros and cons for all but there is one solution coming out from this discussion, which is November-December 2022," said Valcke, adding that the proposal would not please everyone.
