Here's a way to avoid all the tax limitations and reduce paper work.
Keep your car as a personal item, do not sell it to the co.
In 2002 the IRS mileage allowance is 36.5 cents a mile.
That means that your company will reimburse you 36.5 cents a mile for business mileage no matter what car you use. At the end of each month you hand in your expense report to the company detailing mileage, business tolls and parking .
So if you run around a lot this could be the way to go. Simple right? the key here is to keep a daily log.
Not so simple:
You can also lease it and at the end of each month give your company the bill for the lease, tolls, gas, repairs, insurance, etc. (but not mileage). with this method at the end of the year
you need to figure out what your personal percentage use is, i.e.personal mileage/total mileage. This percentage gets multiplied by all your auto expenses (except tolls and parking which should only be for business) and added to your income via W-2, K-1, 1099, etc., depending on the entity. There are also limitations.
BTW the irs seems to like personal percentage in the 30% area.
Then if you buy the car you need to start booking depreciation, and more paper work.
You need to figure out if the added savings of leasing or buying, if any are worth the headache of all the additional paper work.
In any case your accountant should be able to steer you in the right direction.
