What are the False Teachings of Jehovah Witnesses (JWs)?

They doctored the Bible to teach in their New World Translation that where you see Lord it should read Jehovah/Yahweh/YHWH which they claim can only mean the Father.

Jesus is considered "a god" but not the God and the Holy Spirit is not a Person of the Trinity but an energy force.

They teach the unsaved cease to exist and thus do not have to suffer in Hell.

They reject Jesus returns to reign on earth in person, but that he was resurrected in spirit only as an angel.

For JW's salvation is not just believing in their savior, who is not God, but doing necessary works to achieve salvation.

I should point out there have been false prophecies every few years for the end of the world. Whereas what comes next according to Scripture is the millennial reign of Christ in Person on earth for 1000 years.
