Tax Advantages of Business Aircraft Ownership: Depreciation, Deductions, and More
Table of Contents
Business aircraft ownership offers significant tax advantages that can substantially reduce the effective cost of acquisition and operation. From accelerated depreciation that allows you to write off the entire purchase price in the first year, to ongoing deductions for operating expenses, the tax code provides meaningful incentives for businesses that use aircraft.
However, these tax benefits come with strict requirements and potential pitfalls. The IRS scrutinizes aircraft deductions closely, and improper documentation or excessive personal use can trigger audits, penalties, and disallowed deductions. Understanding the rules—and working with qualified tax professionals—is essential for maximizing benefits while staying compliant.
In this comprehensive guide, we'll explore the major tax advantages available to business aircraft owners, explain the requirements for claiming deductions, and provide strategies for maximizing your tax benefits legally. While this guide provides educational information, always consult with a qualified tax professional for advice specific to your situation.

Depreciation Strategies: Section 179, Bonus Depreciation, and MACRS Explained
Depreciation allows you to deduct the cost of business assets over time. For aircraft, several depreciation methods can provide substantial tax benefits.
Section 179 Expensing
Section 179 of the Internal Revenue Code allows businesses to deduct the full purchase price of qualifying equipment in the year it's placed in service, rather than depreciating it over several years.
2026 Section 179 Limits
- Maximum deduction: $1,160,000
- Phase-out threshold: $2,890,000
- Applies to: New and used aircraft
- Requirement: Must be used more than 50% for business
💰 Section 179 Example
Aircraft Purchase: $800,000
Business Use: 85%
Eligible Amount: $800,000 × 85% = $680,000
Section 179 Deduction: $680,000
Tax Savings (37% bracket): $251,600
Effective Cost After Tax Benefit: $548,400
Section 179 Requirements
- Aircraft must be used for business purposes
- Business use must exceed 50%
- Must be placed in service during the tax year
- Cannot create or increase a net operating loss
- Deduction limited to taxable income from active business
Bonus Depreciation
Bonus depreciation allows an additional first-year depreciation deduction on qualifying property. Unlike Section 179, bonus depreciation can create a loss.
Bonus Depreciation Rates
| Year Placed in Service | Bonus Depreciation Rate |
|---|---|
| 2023 | 80% |
| 2024 | 60% |
| 2025 | 40% |
| 2026 | 20% |
| 2027+ | 0% (unless extended) |
Bonus Depreciation Features
- Applies to new AND used aircraft (since 2017)
- No dollar limit
- Can create net operating loss
- NOL can be carried forward
- Applies to business-use portion
MACRS Depreciation
The Modified Accelerated Cost Recovery System (MACRS) is the standard depreciation method for business assets. Aircraft are typically classified as 5-year or 7-year property.
Aircraft MACRS Classification
- 5-year property: Aircraft used in certain commercial activities
- 7-year property: Most general aviation aircraft
MACRS Depreciation Schedule (7-Year Property)
| Year | Depreciation % | On $500,000 Aircraft |
|---|---|---|
| 1 | 14.29% | $71,450 |
| 2 | 24.49% | $122,450 |
| 3 | 17.49% | $87,450 |
| 4 | 12.49% | $62,450 |
| 5 | 8.93% | $44,650 |
| 6 | 8.92% | $44,600 |
| 7 | 8.93% | $44,650 |
| 8 | 4.46% | $22,300 |

Operating Expense Deductions: What You Can Write Off
Beyond depreciation, business aircraft owners can deduct ordinary and necessary operating expenses.
Deductible Operating Expenses
Direct Operating Costs
- Fuel: Aviation fuel for business flights
- Oil and lubricants: Engine and airframe
- Maintenance and repairs: Routine and unscheduled
- Parts and components: Replacement items
- Landing and handling fees: Airport charges
- Parking and tie-down: Transient fees
Fixed Operating Costs
- Hangar rent: Aircraft storage
- Insurance: Hull and liability coverage
- Annual inspection: Required maintenance
- Database subscriptions: Navigation data, charts
- Pilot training: Recurrent training, type ratings
- Management fees: If using management company
Financing Costs
- Interest expense: Loan interest is deductible
- Loan fees: Origination and processing fees
Allocation for Mixed Use
If the aircraft is used for both business and personal purposes, expenses must be allocated:
📊 Expense Allocation Example
Total Annual Operating Costs: $80,000
Total Flight Hours: 200
Business Hours: 150 (75%)
Personal Hours: 50 (25%)
Deductible Expenses: $80,000 × 75% = $60,000
Entertainment Use Limitations
Special rules apply to aircraft used for entertainment:
- Entertainment flights generally not deductible
- Flights to entertainment events may be limited
- Spousal travel may be limited
- Careful documentation required
⚠️ Entertainment Disallowance
The Tax Cuts and Jobs Act of 2017 eliminated deductions for entertainment expenses. Aircraft use for entertainment purposes (sporting events, vacation destinations, etc.) is generally not deductible, even if business is discussed. Consult your tax advisor for specific guidance.
Business Use Requirements: Documentation and Compliance
Proper documentation is essential for defending aircraft deductions in an audit. The IRS requires contemporaneous records of business use.
Required Documentation
Flight Log Requirements
For each flight, document:
- Date of flight
- Departure and destination
- Business purpose
- Passengers and their business relationship
- Flight time (hours)
- Business vs. personal designation
Supporting Documentation
- Calendar entries showing business meetings
- Meeting notes or agendas
- Contracts or business correspondence
- Customer/client records
- Expense receipts
Business Purpose Examples
Clearly Business
- Meeting with clients or customers
- Visiting company facilities
- Attending industry conferences
- Inspecting properties or investments
- Transporting employees for business
Potentially Problematic
- Flights to vacation destinations (even with some business)
- Transporting family members
- Flights to sporting events
- Weekend trips with minimal business activity
The 50% Business Use Test
To claim Section 179 and bonus depreciation, the aircraft must be used more than 50% for business:
Calculating Business Use Percentage
- Based on flight hours (most common)
- Or based on miles flown
- Must be consistent year to year
- Personal use includes commuting
Consequences of Falling Below 50%
- Section 179 deduction recaptured
- Bonus depreciation recaptured
- Must switch to straight-line depreciation
- Significant tax liability can result

Strategic Tax Planning: Timing Purchases and Maximizing Benefits
Strategic planning can significantly enhance the tax benefits of aircraft ownership.
Timing Your Purchase
Year-End Considerations
- Aircraft must be "placed in service" to claim depreciation
- Placed in service = ready and available for use
- December purchase can provide full year's depreciation
- But must actually be ready to fly
Bonus Depreciation Phase-Out
With bonus depreciation declining, timing matters:
- 2026: 20% bonus depreciation
- 2027+: 0% (unless Congress extends)
- Consider accelerating purchase if bonus depreciation is valuable
Entity Structure Considerations
C Corporation Ownership
- Depreciation reduces corporate taxable income
- 21% corporate tax rate
- Personal use may create taxable compensation
- SIFL rules for valuing personal use
S Corporation or Partnership
- Depreciation passes through to owners
- Can offset other income
- At-risk and passive activity rules may apply
- Personal use creates different issues
Sole Proprietorship
- Simplest structure
- Depreciation on Schedule C
- Subject to self-employment tax considerations
- No liability protection
For entity structure guidance, see our entity structures guide.
State Tax Considerations
State Depreciation Rules
- Some states don't conform to federal depreciation
- May require different depreciation calculations
- State tax benefits vary significantly
Sales and Use Tax
- Aircraft purchases may be subject to sales tax
- Exemptions available in some states
- Proper structuring can minimize tax
- See our state taxes guide
Exit Strategy Tax Planning
Selling a Depreciated Aircraft
- Gain on sale is taxable
- Depreciation recapture at ordinary income rates
- Remaining gain may be capital gain
- Plan for tax liability when selling
Like-Kind Exchange Considerations
- Section 1031 exchanges no longer apply to aircraft (post-2017)
- Cannot defer gain through exchange
- Must plan for tax on sale
💰 Depreciation Recapture Example
Original Cost: $600,000
Total Depreciation Claimed: $600,000
Adjusted Basis: $0
Sale Price: $400,000
Gain: $400,000
Depreciation Recapture (ordinary income): $400,000
Tax at 37% Rate: $148,000
