Business owners, this is the single largest planning lever on your 2026 return.
Section 179 expensing for 2026 sits at $2,560,000, double the prior limit. The phase-out does not begin until you place $4,090,000 of qualifying property in service, and it fully phases out at $6,650,000.
Bonus depreciation is back at 100%. Permanently. The old phasedown schedule of 80%, then 60%, then 40% was eliminated. There is no sunset now.
What that means in plain terms. Qualifying equipment, machinery, technology, and certain vehicles can be deducted in full in the year you place them in service, instead of dragged out over five or seven years.
The rules that trip people up:
Placed in service, not purchased. Equipment sitting in a box on December 31 does not qualify. It has to be ready and available for its intended use.
Passenger vehicles under 6,000 lbs GVWR are capped near $20,400 of first-year depreciation under the luxury auto limits.
Heavy SUVs between 6,000 and 14,000 lbs carry a separate $32,000 Section 179 cap, though bonus depreciation can apply above it.
Section 179 cannot create a loss. Bonus depreciation can.
That last distinction is worth real money and it is where a strategist earns their fee. Sometimes taking the full write-off this year is the wrong answer, because you are burning a deduction against income in a low bracket.
We run that math before you buy, not after.
