Section 179 Basics
Section 179 of the IRS code lets you deduct the full purchase price of qualifying business equipment in the year of purchase, instead of depreciating over 5 years. For 2026, the limit is $1,160,000 with a phase-out starting at $2,890,000 in equipment purchases.
What Trailers Qualify?
Most contractor trailers, dump trailers, equipment trailers, and enclosed cargo trailers used for business qualify. The trailer must be:
- Used >50% for business in the year of purchase
- New or used (no requirement for new)
- Tangible personal property
- Acquired by purchase (not leased or gifted)
