Forum Post: How to record 179 expensing?

Hi folks, Our business just bought a Mercedes on 01/16/2016 for 45K and we only expensed $11,060 under section 179. I only booked a JE so far to reflect the purchase: Debit Vehicle account and Credit Cash account. For monthly depreciation, do I calculate it based on the full cost 45K of the vehicle or only $33,940? How do I record the 179 expense in this case? Thank you! Nhi
