"We will officially announce it on Monday (December 11)," said Arab Gulf Cup Football Federation general secretary Jassim al-Rumaihi.
The Gulf Cup has been plagued by problems.
It was originally scheduled to take place in Kuwait last year, but that country's football association was suspended by FIFA in October 2015 over alleged government meddling in sports.
After Kuwait's suspension, the tournament was switched to World Cup 2022 host Qatar.
That did not solve the problem. A bitter dispute erupted on June 5 when Qatar was politically and economically isolated by a quartet of neighbouring countries including Saudi Arabi, UAE and Bahrain over alleged support for terrorist groups and Doha's warming relations with Iran.
Earlier this month, FIFA lifted Kuwait's suspension after the national parliament adopted a law meant to end government interference in the sport.
That cleared the way to move the tournament back to its original host.
"It will take place at exactly the same dates, December 22 to January 5," al-Rumaihi said.
He added that organisers were still waiting to hear from the federations of Saudi Arabia, UAE and Bahrain, but it is widely expected they will now take part in the eight team competition.
Attempts to get the three nations to play in a tournament in Doha failed last month and Saudi, UAE and Bahrain were 'withdrawn' from the competition.
However, following the lifting of Kuwait's suspension, the Qatar Football Association said it was willing for the tournament to go ahead in Kuwait.
The move has been backed by FIFA chief Gianni Infantino who said he would attend the opening games on December 22 and 23.
The Gulf Cup is usually played every two years between Bahrain, Iraq, Kuwait, Oman, Qatar, Saudi Arabia, United Arab Emirates and Yemen.
