Section 179 · Bonus depreciation · Form 4562
Is your truck, SUV or van over 6,000 lbs?
If it is, used more than 50% for business and in service by Dec 31, you may be able to write off most or all of it this year. We show you how, in plain English.
- Find GVWR on the door-jamb label, not curb weight
- Know if the $32,000 heavy-SUV cap applies, or if your truck or van skips it
- Claim it on Form 4562 the right way, and handle your state's add-back
General information, not tax advice.


The three tests
Miss one and your year-one deduction shrinks to a fraction.
GVWR over 6,000 lbs
Gross vehicle weight rating, printed on the driver's door jamb. Under 6,000 lbs, luxury-auto caps apply.
Over 50% business use
Proved with a written mileage log. Commuting doesn't count as business.
