If you’re thinking about buying a private jet — or you already own one — taxes can quietly become your biggest enemy. Not fuel. Not maintenance. Taxes.
And if you get the structure wrong, you don’t just lose money… you invite the IRS straight to your hangar.
I recently dug deep into a conversation with Joe Park, Managing Partner at BizJet CPA, one of the few CPAs in the U.S. who works exclusively in private aviation accounting. What stood out wasn’t just the tax theory — it was how many aircraft owners get this wrong before they even sign the purchase agreement.
Here’s what every private jet owner, high-net-worth individual, and aviation investor needs to understand.
Why Aviation Taxes Are a Completely Different Game
Most people assume aircraft taxes work like real estate or luxury cars. They don’t.
Private aviation lives in a strange intersection where IRS tax law, FAA regulations, and state tax rules all collide. A general CPA might be excellent at corporate tax planning — and still miss critical aviation-specific rules that can cost millions.
That’s why aviation tax planning isn’t optional. It’s survival.
The Three Pillars of Private Aircraft Taxation
Every aircraft owner deals with three major tax categories. Ignore even one, and things get expensive fast.
Yes — your jet is taxable property.
In states like California, property tax on aircraft is usually around 1% of the assessed fair market value, paid annually.
If your jet spends most of its time in that state, there’s no clever workaround. You own it, you pay it.
This alone can mean hundreds of thousands per year on large cabin jets.
Sales & Use Tax on Aircraft Purchases
This is where people lose sleep.
Sales or use tax is a one-time hit, but it’s brutal.
In states like California, you’re looking at 6% to nearly 10% of the purchase price.
That means:
- $10M jet → ~$900,000 tax
- $60M jet → ~$5M+ tax bill
And that’s just for buying the aircraft.
Smart Owners Never Take Delivery in the Wrong State
Experienced aircraft owners almost never take delivery in high-tax states.
Popular delivery strategies include:
- Montana (no sales or use tax)
- Fly-Away states like Texas or Kansas
- Capped tax states like South Carolina (very low max tax)
Where and how you close the deal matters more than most buyers realize.
Income Tax & Aircraft Depreciation
This is the most complex — and the most abused.
An aircraft is not automatically a tax write-off, no matter how rich you are.
You must:
- Have a real business
- Tie the aircraft to that business
- Prove legitimate business use
The IRS looks closely at:
- Passenger manifests
- Flight purpose
- Business vs personal usage
If your family or friends are onboard, deductions get limited — fast.
Business Use: The Biggest IRS Red Flag
Aircraft are considered “listed property” by the IRS — meaning they’re prone to abuse.
Translation:
👉 You must prove every business flight
👉 No documentation = deductions reversed
The IRS now routinely asks:
- Who was onboard?
- Why was the flight taken?
- What business purpose did it serve?
If you can’t show clean records, even a valid deduction can be denied.
Bonus Depreciation: Powerful, But Dangerous If Misused
Bonus depreciation has been one of the biggest tax advantages in private aviation.
But here’s the catch:
- You must maintain 50%+ qualifying business use
- This test applies every year
- Audits are increasing — fast
Joe mentioned multiple aircraft audits where:
- Owners with clean records walked away untouched
- Sloppy operators faced serious adjustments
Depreciation isn’t about being aggressive.
It’s about being defensible.
91 vs 135 Operations: Tax vs Liability Trade-Off
Aircraft owners constantly ask:
“Should I charter my aircraft?”
Here’s the reality:
Part 91 (Private Use)
No reimbursement allowed
Fewer FAA restrictions
More tax flexibility in some cases
Higher liability exposure
Part 135 (Charter)
- Commercial operations allowed
- Can offset costs with charter revenue
- Heavy FAA compliance
- Possible passive activity loss limitations
Running your own 135 just for tax benefits?
Almost never worth it.
Most smart owners:
- Use a reputable charter management company
- Avoid running a standalone charter operation
Why Timing Matters More Than People Think
One of the biggest mistakes Joe sees?
Calling an aviation CPA after the purchase.
By then:
- Delivery location is locked
- Entity structure may be wrong
- Financing documents need cleanup
The right time to talk to an aviation CPA is:
👉 Before signing the LOI
👉 Ideally when you first start shopping
Especially if you’ve recently exited a company or had a large liquidity event.
High Net Worth Doesn’t Mean Automatic Write-Offs
This surprises many wealthy buyers.
Selling a company for nine figures doesn’t magically make a jet deductible.
If there’s no operating business to attach the aircraft to, there is no write-off.
The IRS doesn’t care how big your bank balance is — only business purpose matters.
Private jets are not real estate.
They follow a completely different section of tax law.
Monthly Reporting: Your First Line of Defense
The best-run flight departments don’t scramble at tax time.
They:
- Capture passenger data monthly
- Maintain clean flight logs
- Align management reports with tax records
Poor reporting is one of the fastest ways to escalate an audit.
Clean records = faster audits, fewer questions, lower risk.
The Real Cost of Owning a Private Jet
Here’s the truth most brokers won’t say clearly:
Private aircraft are rarely cash-flow positive.
Charter helps, but it doesn’t magically fix economics.
Maintenance surprises, pilot turnover, and downtime can wipe out projected savings in a single year.
Aircraft ownership is:
- A business tool
- A tax strategy (when done right)
- A luxury — not an investment
Final Thought: Aviation Tax Strategy Is a Team Sport
The smartest aircraft owners don’t work in silos.
They align:
- Aviation CPA (tax & depreciation)
- Aviation attorney (liability & FAA compliance)
- General CPA (overall tax planning)
There’s always a trade-off between:
- Maximizing deductions
- Minimizing liability
You rarely get both at 100%.
The goal is balance — not aggression.
If You’re Even Thinking About Buying a Jet…
Have the tax conversation first.
Not after delivery. Not after closing.
That single step can save millions — and keep the IRS exactly where it belongs: far away from your aircraft.
