That's not accurate. A tax write-off isn't "taxes you don't pay". It's "lost income that isn't taxed".

The US corporate income tax is nominally 21%. If a company writes off 100 of loss (or charitible donations, or expenses, or anything else), their earnings are reduced by 100 dollars, saving them 21 bucks. There's no way to "profit" off of failure through write-offs.
