100% Bonus Depreciation & the One Big Beautiful Bill Act
Congress restored 100% first-year bonus depreciation for qualifying private aircraft through the One Big Beautiful Bill Act (OBBBA), signed July 4, 2025. For business owners acquiring a PC-12 through SprintBach, this creates a rare convergence: an asset that generates charter revenue, reduces management overhead, and delivers a potential seven-figure Year-1 tax deduction.
What Bonus Depreciation Actually Means
Under standard tax rules, aircraft depreciate gradually over 5–7 years using MACRS schedules. Bonus depreciation under IRC Section 168(k) bypasses that entirely — letting you deduct the entire purchase price in the year the aircraft enters service. Congress has used this tool before: post-9/11 in 2001, during the 2008 financial crisis, and through the 2017 TCJA. The OBBBA is the latest iteration — and comes with the most favorable terms yet.

The Financing Leverage Strategy
Financing does not reduce your deduction. A buyer who puts 20% down on a $5M aircraft ($1M out of pocket) still deducts the full $5M — generating approximately $1.85M in tax savings at top rates. That means your tax savings exceed your down payment. This is not a loophole; it is the explicit design of the legislation and a widely used acquisition strategy.
📈
Deduction equals purchase price
A $5M PC-12 NGX generates a $5M Year-1 deduction. At 37% effective rate, that is approximately $1.85M in actual tax savings. C-corps deduct at 21% flat; pass-through entities flow the deduction to the owner’s personal return.
⏰
Timing is binding
The aircraft must be placed in service by December 31 of the year you claim the deduction. Aircraft inspection facilities fill up toward year-end — buyers who plan ahead have more time for proper due diligence and avoid year-end premium pricing.
📄
Documentation is non-negotiable
Flight logs documenting purpose, passengers, and destinations for every flight — recorded contemporaneously, not reconstructed. Written business justification per flight. Maintenance records proving placed-in-service date. Ownership structure documentation.
📍
Inventory is tightening
Bonus depreciation reinstatement historically drives increased demand and tighter inventory on quality used aircraft. PC-12s with clean maintenance records and 135 pedigree are finite. Early movers in a depreciation cycle historically secure better aircraft at better prices.
Who Benefits Most — and Who Should Proceed Carefully
✓ High-Impact Profiles
Business owners with strong active income
Entrepreneurs with a capital gain event this year (sale, exit, distribution)
Private equity professionals and family offices with geographically dispersed operations
High-income executives with regular business travel requirements
Owners who can structure Part 135 charter to substantiate business use
⚠ Proceed Carefully
Passive investors with primarily W-2 income (§469 PAL rules apply)

Sole proprietors with high personal use — cannot use the compensation exception under §280F
Taxpayers subject to alternative minimum tax limitations
How SprintBach Changes the Ownership Equation
Bonus depreciation transforms economics — but SprintBach’s Part 135 charter program multiplies the effect. Rather than owning an aircraft that delivers only a tax deduction, SprintBach owners hold an asset that generates charter revenue, offsets management costs, and protects the depreciation deduction simultaneously.
Every charter hour SprintBach flies counts as Qualified Business Use toward the §280F 50% threshold. At 30 charter hours per month, you enter each year with 360 verified QBU hours before your own flights are counted. Combined with Qmulus Aviation’s Part 145 maintenance infrastructure, SprintBach owners have access to a fully integrated aviation platform that independent owners cannot replicate.
Frequently Asked Questions
Is 100% bonus depreciation actually available for aircraft purchases in 2025?+
Yes. For qualifying aircraft acquired and placed in service after January 20, 2025, 100% bonus depreciation is available under the One Big Beautiful Bill Act signed July 4, 2025. Both new and pre-owned aircraft qualify, provided you have not previously owned that specific aircraft and it maintains over 50% business use annually under IRC §280F(b).
Does financing affect my bonus depreciation deduction?+
No. Financing does not reduce your deduction. You can finance 80% of the aircraft and still deduct 100% of the full purchase price in Year 1 — not just the amount you paid in cash. A buyer who puts $1M down on a $5M aircraft can generate $1.85M in tax savings, exceeding the down payment. Your CPA should model the net cash position explicitly before closing.
Do SprintBach’s Part 135 charter hours count toward my 50% business use requirement?+
Yes. Hours flown under SprintBach’s FAA Part 135 operating certificate qualify as commercial air transportation — a recognized category of qualified business use under IRC §280F. These hours count toward your annual QBU percentage alongside your own business flights. For entity-owned aircraft (C-Corp, S-Corp, Partnership), SprintBach charter hours also satisfy the 25% non-owner QBU threshold that unlocks the more favorable two-step test. Your aviation tax attorney should document this structure properly.
What happens if my business use falls below 50% in a later year?+
If Qualified Business Use drops below 50% in any year within the 6-year recapture window, the difference between what you claimed under bonus depreciation and what the Alternative Depreciation System (ADS) would have allowed must be recognized as ordinary income in that year — not capital gains. On a $5M aircraft with 100% Year-1 bonus depreciation, a failure in Year 2 could mean $4M+ of ordinary income. SprintBach charter hours create a meaningful annual buffer against this risk, but per-passenger QBU documentation remains essential every year.
Does personal use disqualify my bonus depreciation?+
Personal and entertainment flights do not count toward your Qualified Business Use calculation, and entertainment flights carry additional risk of §274 expense disallowance. However, personal use does not automatically disqualify you — it reduces your QBU percentage. As long as your total QBU (business flights plus SprintBach charter hours) stays above 50% annually, you remain qualified. Owners with significant personal use should use entity ownership structure (C-Corp, S-Corp, or Partnership) rather than direct sole proprietor ownership, which cannot use the compensation exception.
Can I use SprintBach as my management company and still claim bonus depreciation?+
Yes. Using a professional aircraft management company does not disqualify you from bonus depreciation. The management agreement should be structured at arm’s length to avoid related-party issues under §280F, and you must still meet the 50% business use requirement with proper documentation. SprintBach provides QBU-formatted flight logs for every charter hour as a standard part of the program. Your aviation tax attorney should review the management agreement structure prior to going under contract.
Should I take 100% bonus depreciation in Year 1, or elect out and use straight-line MACRS?+
This depends on your income trajectory and whether the deduction can be fully absorbed in the current year. If you have substantial taxable income now, 100% in Year 1 maximizes immediate savings. If you expect meaningfully higher income in future years, electing out under IRC §168(k)(7) and using straight-line MACRS could shift larger deductions to higher-rate years. A third option — partial election — allows strategic spreading across multiple years. Model all three scenarios against your projected charter income over Years 1–6 before deciding with your CPA.
What documentation is required to support a bonus depreciation claim?+
Required documentation includes: (1) contemporaneous flight logs for every flight — date, origin, destination, specific business purpose, and names of all passengers — recorded at or near the time of the flight, not reconstructed; (2) written business justification per flight; (3) maintenance records demonstrating placed-in-service date; and (4) proper ownership structure documentation. SprintBach provides IRS-formatted logs for all Part 135 charter hours. Your own business flights require a separate system. Inadequate records are the most common trigger for IRS challenges on aircraft depreciation claims.
Is the window really through 2030, or could Congress change it?+
The OBBBA extends bonus depreciation through 2030 for most qualifying property, and through 2031 for certain long-production-period aircraft. It was structured with permanent intent — no built-in phaseout. However, Congress retains the ability to modify tax law at any time. The TCJA’s 100% provision was itself modified in 2023. The safe approach: plan and execute within the current statutory window rather than relying on indefinite availability. For buyers with strong taxable income and a genuine business aviation need, current terms are among the most favorable in decades.
