Judicial sources said Hussein al-Dhafiri, whose wife was also arrested, confessed to planning suicide attacks on a US military convoy and a Shiite hall, the Al-Rai daily reported.
Kuwait’s Arifjan Base houses several thousand US troops and serves as a military transit point to Iraq and Afghanistan.
Home to a small Shiite minority, Kuwait was the site of a suicide attack linked to the IS back in June 2015.
A Saudi suicide bomber killed 26 in a Shiite mosque, the worst such attack in the Gulf state’s history.
Dhafiri was deported earlier in April to Kuwait where he is now set to stand trial on charges of belonging to a banned organization and plotting attacks, Al-Rai said.
He had been arrested in Manila along with his wife, whom he married after her high-ranking IS commander husband was killed in Syria.
They also said there had been tentative plans to target a church in Kuwait during a visit this week by Coptic Pope Tawadros II.
Kuwaiti courts have handed down multiple convictions on charges of IS membership or financing.
Some of the defendants have been found guilty of fighting with the jihadists in Iraq or Syria. All have received lengthy jail sentences.
A lower court in December sentenced a Filipina to 10 years in jail after convicting her of joining the jihadist group and plotting attacks.
