For 2026, the practical move is to elect Section 179 first on priority assets, up to the $2,560,000 cap, then apply 100% bonus depreciation to whatever eligible basis remains. Section 179 is elective, asset-by-asset, and limited to your taxable income from active business. Bonus depreciation applies automatically, has no income cap, and can create a net operating loss you carry forward.
TL;DR:
- Bonus depreciation applies automatically, with no income cap, and can create net operating losses to carry forward, covering most equipment classes.
- Sequence matters: applying Section 179 first on priority assets, then bonus depreciation on remaining basis, maximizes flexibility and deduction benefits.
- Many states do not conform to federal bonus depreciation, requiring an add-back, so consider state rules before electing deductions.
- Early asset disposition can trigger recapture taxes, making careful planning essential when using accelerated depreciation strategies.
The two deductions solve the same problem: writing off equipment costs in the year you buy rather than over several years, but they work through completely different mechanics.
Section 179 is a deduction you choose. You pick specific assets, specific dollar amounts, and you’re capped by how much taxable income your business actually generated that year. If your business shows a loss, Section 179 mostly sits on the shelf until future profitable years, since it can’t create or increase a net operating loss. Bonus depreciation, restored to 100% by the One Big Beautiful Bill Act for property placed in service after January 19, 2025, applies by default across an entire asset class unless you formally elect out. There’s no dollar cap and no income limitation, which means it can push you into an NOL on purpose.
That difference shows up fast in practice:
Statistic to know: For 2026, the maximum Section 179 deduction is $2,560,000, phased out dollar-for-dollar once qualifying purchases exceed $4,090,000. Bonus depreciation carries no equivalent ceiling.
Section 179 lets you deduct up to $2,560,000 of qualifying equipment in 2026, but that number starts shrinking once total purchases cross $4,090,000, and it disappears entirely once purchases exceed the combined threshold, per the Form 4562 instructions. This phase-out targets the deduction at genuinely small and mid-size businesses rather than large capital spenders.
A few rules trip up first-time filers:
Miss the itemization requirement and the IRS can disallow the election outright, so keep a clean asset ledger from day one.
The One Big Beautiful Bill Act restored 100% bonus depreciation for qualifying property acquired and placed in service after January 19, 2025, reversing the phase-down schedule that had been dropping the rate toward zero, according to IRS guidance. That’s the single biggest planning shift heading into 2026.
Bonus depreciation applies broadly, but not to everything:
Statistic to know: Bonus depreciation is permanently set at 100% for qualifying property placed in service after January 19, 2025.
The trap: if you elect out of bonus for, say, all five-year property to preserve state conformity, you lose bonus on every asset in that class, including ones you’d rather have accelerated.
Run the two deductions in order, not simultaneously, and the sequence matters because it determines how much control you keep over which assets get accelerated.
Two examples show why order matters.
Example A: $200,000 equipment purchase, profitable year. A machine shop buys $200,000 in CNC equipment. Well under the Section 179 cap, so the business elects §179 on the full amount, deducting it immediately and keeping bonus depreciation available for next year’s purchases. Bonus-first would produce the same first-year number here, but §179-first preserves flexibility if the business later disposes of some equipment early.
Example B: $4.3 million spend, expansion year. A manufacturer buys $4.3 million in machinery. That exceeds the $4,090,000 phase-out threshold by $210,000, cutting the available Section 179 deduction dollar-for-dollar, according to Section179.org’s comparison guide. The business elects §179 on the reduced amount, then applies 100% bonus depreciation to the remaining basis, likely creating a net operating loss it carries forward.
| Scenario | Section 179 used | Bonus depreciation covers | Result |
|---|---|---|---|
| $200,000 equipment | Full $200,000 | Not needed | Full deduction, no NOL |
| $4.3 million machinery | Reduced by phase-out | Remaining basis | Large deduction, likely NOL |
Electing out of bonus by class makes sense mainly when you want to smooth deductions across profitable years rather than front-load everything into one year that’s already low-tax.
Federal rules are only half the picture. A meaningful number of states decouple from federal bonus depreciation, requiring an add-back on the state return even though the federal deduction stands, according to tax practitioner analysis of the OBBBA changes. Section 179 tends to fare better at the state level, since more states allow it in some form.
Run this checklist before you elect anything:
Pro Tip: Run the state add-back calculation before you file, not after. A business that assumes state conformity matches federal treatment often discovers the mismatch during an audit, when it’s far more expensive to fix.
Both deductions get reported on Form 4562, which the IRS provides detailed instructions for, covering Section 179 elections on one set of lines and bonus depreciation under the additional first-year depreciation section.
Keep these items on hand:
Recapture catches people off guard more than any other part of this process. Sell an asset early and you may owe back a portion of what you deducted, so factor that risk into which assets you accelerate.
Match the tool to your year, not a blanket rule.
Accelerated expensing changes your cash position fast, and that shift deserves the same attention as the tax return itself. A large first-year deduction frees up cash that can either sit idle or get redeployed into financing that matches the useful life of what you just bought. Pairing tax strategy with equipment financing preserves working capital instead of tying it all up in one purchase. Talk to both your tax advisor and your lender before you finalize either decision.

Accelerated deductions cut your tax bill, but they don’t solve the upfront cash problem of buying real estate or heavy equipment in the first place. That’s where Fbdc fits. As a Florida-based SBA 504 lender with more than 35 years in the business, Fbdc offers down payments as low as 10% and long-term fixed rates, which means you can finance the acquisition while your Section 179 and bonus depreciation elections do the work of lowering your tax bill in the same year.
Businesses buying equipment with SBA 504 financing may pair low down payment loans with immediate expensing, spreading the acquisition cost over a fixed-rate term while capturing the deduction upfront. That combination keeps working capital free for payroll, inventory, or the next expansion phase instead of locking it into a single purchase. If you’re weighing a machinery buy or a facility acquisition against your 2026 tax picture, start with Fbdc’s six-step SBA 504 loan process to see how the financing timeline lines up with your depreciation strategy.
