What happened

Shares of electric car stock Tesla (NASDAQ:TSLA) slumped more than 5% in early trading Wednesday before paring its losses to close the day down 2.3%.

Granted, most stocks closed the day down Wednesday -- the S&P 500 Index lost 1.75%. But Tesla's decline in particular was interesting given the context of what's happening with the company in California...and in Texas.

So what

You've probably heard about the troubles Tesla is having in California lately. In March, the state government ordered the company's Fremont car factory closed out of concerns over coronavirus. Last week, CEO Elon Musk began making plans to open operations back up, and yesterday, President Trump threw his Twitter weight behind the idea, encouraging Musk to "open the plant, NOW!" despite California not yet having given its approval to such a move.

At the same time, Texas is trying to woo Tesla to relocate its operations a bit to the south and east of California, and as Reuters reported this morning, Musk is now talking with Texas Governor Greg Abbott about potentially moving his car factory to the Lone Star State.  

Now what

Making that move might sound like a good idea to Musk -- after all, he already has a Texas operation set up for his SpaceX space company, which is building its shiny new Starship space vehicle in Boca Chica -- but a move to Texas wouldn't be an unalloyed boon to Tesla.

According to the independent nonprofit Tax Foundation, a tax policy advisory organization, California ranks 48 out of 50 states for "overall" business climate, while Texas is a much friendlier place to do business -- ranking No. 13 on the Tax Foundation's list.  

When it comes to corporate taxes in particular, however, the Tax Foundation notes that California has a very high 8.84% corporate income tax (which is bad), but Texas, although it has no corporate income tax, does impose a "gross receipts tax" of 1% of gross income over $1 million. Calculated thus differently from corporate income taxes, gross receipts taxes "are generally thought to be more economically harmful than corporate income taxes," warns the Tax Foundation.  

The prospect of Tesla moving itself into a new tax-regime state may be making it harder for investors to gauge the net effect on Tesla's bottom line -- and that could be what's giving investors pause about investing in Tesla today.
