The new Gigafactory in Texas is expected to be completed by the end of the year, and will cost more than $1 billion.
The electric vehicle company would spend almost half a billion dollars on the general assembly section and the body shop. The facilities for these sections will be finished by the end of the year according to the documents. The five facilities cost over $1 billion.
The filings were first reported by Electrek.
The project is expected to create 10,000 jobs and the company is expected to receive $65 million in local tax refunds.
The plant in Texas comes as other companies in the tech sector, including Hewlett Packard Enterprise, are moving their headquarters from the San Francisco Bay Area to Texas.
"Gigafactory Texas is progressing as planned," the company said in a shareholder slide deck. We are in the process of making our first vehicles.
There are also factories in California, Nevada, and Shanghai, as well as a plant near Berlin, Germany.
The completion of the gigafactory follows Musk's move to Austin. Many speculated that Texas' lack of state income tax played a part in Musk's decision to leave California in December 2020.
The last of Musk's California properties, a 47-acre estate in Hillsborough, near San Francisco, is close to being sold.
