How Section 179 Works

The IRS lets businesses deduct the full purchase price of qualifying equipment — including vehicles — in Year 1 instead of depreciating over 5-6 years.

01

Section 179 Deduction

Deduct the purchase price immediately. SUVs capped at $30,500 (2025). Trucks with 6ft+ beds: NO CAP — deduct the full price.

02

Bonus Depreciation

Whatever Section 179 doesn't cover, bonus depreciation takes a percentage of the remainder. 60% in 2025, phasing to 0% by 2028.

03

MACRS Depreciation

Whatever's left depreciates over 5 years using the IRS MACRS half-year schedule: 20%, 32%, 19.2%, 11.52%, 11.52%, 5.76%.

Key Requirements

Vehicle GVWR must exceed 6,000 lbs
Business use must exceed 50%
Must be placed in service during the tax year claimed
Any entity: sole prop, LLC, S-Corp, C-Corp, partnership
Used vehicles qualify (must be new-to-you)
Personal use portion is not deductible

How the Money Actually Comes Back

The "discount" isn't a rebate check. It's money you never pay to the IRS.

Option 1

Lower Quarterly Payments

If self-employed / S-Corp, your quarterly estimated tax payments drop immediately. You keep the money you would've sent to the IRS.

Option 2

Tax Refund at Filing

If you overpaid via W-2 withholding or estimated taxes, the savings show up as a refund — direct deposit in 2-4 weeks after e-filing.

Option 3

Offset Tax Owed

If you owe $80K without the truck, you'd owe $38K with it. The $42K stays in your bank account.

What Triggers an Audit

Claiming 100% business use on multiple vehicles
Buy-and-sell in short windows (looks like a scheme)
No mileage log to back up business use %
Vehicle doesn't match your business type

Keep a mileage log. Apps like MileIQ or Everlance do it automatically. That's your #1 protection.

The Resale Trap WARNING

Can you buy, deduct, and flip for profit? No. The IRS thought of that.

When you deduct $75K via Section 179, your adjusted basis drops to $0. When you sell, the entire sale price is taxable gain at your ordinary income rate (Section 1245 recapture).

The Only Ways to Actually Win

1.
Use it for business and keep it. The deduction is real if you need the vehicle. A $75K truck costs you $43.5K.
2.
Sell in a low-income year. Buy at 37% bracket, sell when income drops. Recapture at 22% = keep the 15% spread.
3.
Die with it. Stepped-up basis at death eliminates recapture entirely. Heirs inherit at market value.
4.
Trade-in on another business vehicle. Defers recapture, keeps the cycle going indefinitely.

The Bottom Line

Section 179 is a cash flow accelerator. Instead of deducting over 6 years, you get it all in Year 1. That money in your pocket today can earn returns, fund your business, or eliminate debt. The time value of money is the real benefit — not a flip scheme.
