Chief executive Elon Musk announced the move at the electric carmaker’s annual shareholders’ meeting in Austin.
Mr Musk had fallen out with local politicians in Alameda county, California, the location of a key Tesla factory, over its Covid response.
He gave several reasons for the move, telling shareholders its Californian factory in Fremont was “jammed”.
California was also a difficult place for his employees to find affordable housing, he told shareholders.
“There’s a limit to how big you can scale it in the Bay Area. In Austin our factory is like five minutes from the airport, 15 minutes from downtown,” he said.
The billionaire technology entrepreneur has had an fractious relationship at times with California.
In May, Musk had a high profile spat with local politicians in California after he was ordered to keep Tesla’s Fremont plant closed.
He tweeted: “Tesla will now move its HQ and future programs to Texas/Nevada immediately.” However the move had not been confirmed until now.
Tesla is filing a lawsuit against Alameda County immediately. The unelected & ignorant “Interim Health Officer” of Alameda is acting contrary to the Governor, the President, our Constitutional freedoms & just plain common sense!
“This is not a matter of, sort of, Tesla leaving California,” he said.
Tesla is not the first company to move to Texas. In 2020, tech powerhouse Oracle announced it was moving from Silicon Valley to Austin.
Technology firm HP and carmaker Toyota have also moved their US headquarters to Texas from California.
California has stronger labour laws, and higher living costs and taxes than other states, while Texas is known for cheaper labour and less stringent regulation.
Mr Musk moved his home to Texas from California at the end of last year to focus on Tesla’s new car manufacturing plant there.
His SpaceX rocket company has a launch site in the southern tip of Texas.
