Can I deduct fsd on my taxes? a full time Uber driver with a Tesla, am I able to deduct full self driving ($199 monthly) as a business expense on my business vehicle?

Yes, this would be considered a subscription service so you would be able to deduct it on your taxes as Other Miscellaneous Expenses.  

To enter this, once you are in the business section select Business Expenses, Other Common Expenses, Other Miscellaneous expenses. Then enter the amount and what it is for.  

If you use this vehicle for personal use as well, you will need to prorate the subscription fee based on personal versus business use.
