Dear Tesla Stock Fans, Mark Your Calendars for September 30

Few events on the calendar carry as much weight for U.S. electric vehicle buyers — and Tesla (TSLA) investors — as Sept. 30, 2025. That date marks the end of the $7,500 federal EV tax credit under U.S. President Donald Trump’s “One Big Beautiful Bill Act,” signed into law in July. The move effectively shortens what was, under the President Joe Biden-era Inflation Reduction Act, a generous incentive slated to run through 2032. Now, with the clock ticking, the U.S. EV market is bracing for a major shift.

In this article, we’ll explore what the Sept. 30 deadline means for Tesla, how it could reshape U.S. EV demand, and why investors should mark their calendars for what may be one of the most pivotal dates for TSLA stock in 2025.
