Hi Douglass, in order for you to claim the section 179 deduction for a “used” vehicle, it must be new to you. This means that you purchased it used sometime between January-December of the tax year. It cannot be a personal vehicle that just started using for business. I am not familiar with having to make the purchase in September. However, you should contact a tax pro who can assess your specific situation and give you tax advice, which I am not able to do.
Thank you for reading!
