Full first-year write-offs for equipment are permanent now, and the Section 179 limit is bigger for 2026. A calm look at what that actually means before you sign for a truck.
If you've been putting off a truck or trailer purchase because you weren't sure what the tax picture would look like, here's the update: 100% bonus depreciation is no longer a temporary thing Congress might let expire. Under last year's tax law, it's permanent for qualifying property acquired after January 19, 2025. And Section 179, the other big equipment deduction, got a bump too — the maximum you can expense for 2026 is $2,560,000, with the phase-out not starting until you place more than $4,090,000 of qualifying property in service in a year. For almost every owner-operator, that phase-out simply won't come into play.
In plain terms: if you buy a qualifying truck, trailer, or piece of equipment and put it into business use, you can generally deduct the entire cost in the year you place it in service, instead of spreading it out over several years of depreciation schedules. That's a real difference from where things stood just a couple of years ago, when bonus depreciation was scheduled to keep shrinking every year until it hit zero. That phase-down got reversed. It's back to 100%, and it's written into the code as permanent rather than an on-again, off-again provision.
Section 179 works alongside bonus depreciation rather than instead of it — it lets you elect to expense the cost of qualifying property up front, subject to that $2,560,000 cap for 2026. Whichever combination of the two applies to your purchase, the practical effect for most owner-operators buying a truck this year is the same: a much bigger deduction, much sooner, than the old depreciation schedules would have allowed.
Your third-quarter estimated tax payment is due September 15. If you're weighing a truck or trailer purchase for this year anyway, timing it before year-end — rather than waiting until January — could meaningfully change what you owe for 2026, and that's exactly the kind of thing that's easier to plan for now than to discover after the fact. This isn't a reason to buy equipment you don't need. It's a reason to have the real numbers in front of you before you decide, instead of guessing.
If you're already planning to buy or upgrade a truck this year, pull together the purchase price, the date you expect to place it in service, and your projected 2026 net income — then look at how a full first-year deduction would actually shift your tax picture before you commit to a purchase or a payment schedule. Knowing the number ahead of time beats finding out at filing season.
How this plays out depends on the type of vehicle, how it's used, and whether you're buying outright or financing — and it genuinely does depend on your specific setup rather than a blanket rule. A few things shift the math: whether the vehicle is used more than half the time for business, how it's classified by weight, and what else you've already placed in service this year. This is general, educational information, not a recommendation for your specific purchase — if you're weighing a real equipment decision, that's worth running past someone who can look at your actual numbers rather than guessing from a blog post.
Equipment decisions are exactly the kind of thing a mid-year check-in is built to catch before they turn into a scramble at tax time.
