Tax Breaks for Private Jet Owners: Depreciation, Deductions, and Audits

Tax breaks for private jet owners come in two main forms: a first-year deduction for the full purchase price of the aircraft, and ongoing deductions for the cost of operating it. Both depend on using the plane primarily for business, and both are governed by rules that have gotten stricter to document even as they have gotten more generous to claim. The One Big Beautiful Bill Act of 2025 made 100% bonus depreciation permanent for qualifying business aircraft, and the IRS has responded by opening a dedicated audit campaign to check that owners are actually meeting the requirements.

Writing Off the Purchase Price in Year One

A business aircraft acquired and placed in service after January 19, 2025 qualifies for 100% first-year bonus depreciation with no scheduled expiration.¹ The provision covers both new and pre-owned jets, provided it is the buyer’s first use of the plane. For a $20 million aircraft placed in service during 2026, the owner can deduct the full $20 million against taxable income in the year of purchase rather than spreading the cost over five or six years.

“Placed in service” is doing real work in that sentence. The aircraft must be delivered and ready for its intended business use during the tax year in which the deduction is claimed. Sign a purchase agreement in December, take delivery in January, and the deduction lands in the following year.

Section 179 expensing runs alongside bonus depreciation as a second first-year write-off route. Aircraft qualify as tangible personal property used in a trade or business, making them eligible.² The 2025 law raised the base Section 179 limit to $2.5 million, indexed for inflation, with the deduction phasing out once total qualifying property placed in service exceeds roughly $4.09 million for tax years beginning in 2026. On its own, Section 179 rarely covers a jet’s full cost, but it works as a complement to bonus depreciation or as a fallback when bonus depreciation is unavailable.

The Qualified Business Use Tests

Every accelerated write-off for a private aircraft runs through Section 280F. The plane must be used more than 50% of the time for qualified business purposes in the tax year to remain eligible for bonus depreciation, Section 179, or standard MACRS depreciation.³ Fall below 50%, and the owner is pushed onto the Alternative Depreciation System, which uses straight-line depreciation over six years for non-commercial aircraft or twelve years for commercial aircraft.⁴

Aircraft face a second test that most business property doesn’t. At least 25% of the plane’s total use during the year must be qualified business use that excludes certain flights by owners holding 5% or more of the company and by related persons.³ A jet flown exclusively by a company’s majority owner doesn’t automatically pass the test even if every flight has a real business purpose. Some flights need to involve employees who aren’t significant owners or related parties.

Commuting is the trap owners walk into most often. Flights between an owner’s or employee’s home and a regular place of work are commuting under Section 274(l), and the costs of operating the aircraft for those trips are not deductible.⁵ The only exception is travel necessary for the employee’s safety. Those hours count against the qualified business use calculation and generate no offsetting deduction.

If business use passes the 50% threshold in early years but drops below it later, the IRS recaptures the difference between the accelerated depreciation already claimed and the amount that would have been allowed under ADS, treating the excess as ordinary income.³

All of this rests on contemporaneous records. The IRS expects documentation showing the expense amount, the time and place of travel, the business purpose, and the business relationship of each person on the aircraft.² Weak logbooks are where most aircraft audits gain traction.

Deducting Operating Costs

Beyond depreciation, the recurring costs of running a business aircraft reduce taxable income as ordinary and necessary business expenses under Section 162. Deductible items include fuel, hangar fees, insurance premiums, and pilot and crew salaries.⁶ Routine maintenance and FAA-mandated inspections are fully deductible. Fuel alone can reach into the hundreds of thousands of dollars a year on a frequently flown jet, so these deductions meaningfully offset the cost of ownership.

The business-versus-personal split applies here too. If 70% of the aircraft’s use is for business and 30% is personal, only 70% of operating costs come off the tax return. The IRS expects detailed invoices, proof of payment, and records tying each expense to business operations. Owners who run expenses through a management company still need their own books.

What Personal and Entertainment Flights Cost

When a company aircraft carries someone on a personal trip, the value of that flight is taxable income to the passenger. Employers can calculate the value using either the fair charter rate or the Standard Industry Fare Level formula. SIFL rates, published twice a year by the Department of Transportation, use a mileage-based formula plus a per-flight terminal charge.⁷ SIFL usually produces a lower taxable value than the flight’s actual operating cost, which is why most employers use it. It can only be applied on an originally filed return, not on an amendment.

The company-side hit is larger. When a flight qualifies as entertainment for a “specified individual,” the business can only deduct the amount reported as compensation for that person, not the actual cost of the flight.⁸ A specified individual includes any officer, director, or person who owns more than 10% of the company.⁹ If a flight to a vacation home actually costs $30,000 to operate but the SIFL compensation value reported for the executive is $4,000, the company deducts $4,000. The remaining $26,000 is nondeductible. Heavy personal use by top executives can erode the tax benefits of ownership faster than most owners expect.

Leasing the Aircraft to a Business

Owners who lease their aircraft to a business, including one they control, run into Section 469. Rental activities are generally passive, so losses from the aircraft can only offset other passive income and cannot reduce wages, active business income, or investment gains.¹⁰ Excess losses carry forward but provide no immediate tax relief. Escaping passive treatment requires meeting one of the IRS’s material participation tests or making a grouping election that combines the aircraft leasing activity with another active business as a single appropriate economic unit. Groupings are legitimate but heavily scrutinized, and unwinding a bad one is difficult.

Recapture When You Sell

Large first-year deductions come with a bill at the back end. When a business aircraft sells for more than its depreciated basis, Section 1245 recaptures the gain attributable to prior depreciation as ordinary income, taxed at ordinary rates rather than at capital gains rates. An aircraft fully expensed under 100% bonus depreciation has a basis of zero, so the entire sale price up to the original purchase price is recaptured.

A jet bought for $15 million and fully expensed in year one, then sold three years later for $10 million, produces $10 million in ordinary income. The deduction wasn’t lost; the tax benefit converts from a permanent savings into a timing advantage.

Rolling the sale into another aircraft to defer the gain isn’t an option anymore. The 2017 Tax Cuts and Jobs Act eliminated like-kind exchanges for personal property, so Section 1031 now applies only to real estate.¹¹ Recapture is now an unavoidable part of the ownership lifecycle.

State Sales and Use Taxes

Federal breaks aren’t the whole tax picture. State sales and use taxes can add a substantial upfront cost. Rates and rules vary by jurisdiction. A handful of states impose no general sales tax on aircraft purchases; others apply their standard rate, which can produce a six- or seven-figure bill on a multimillion-dollar jet. Many states offer exemptions for aircraft used in interstate commerce, purchased for resale, or flown out of the state within a set number of days after purchase. Use tax creates a secondary trap: buy in a no-tax state and base the aircraft in a state that levies use tax, and the tax comes due when the plane arrives at its home hangar. An aviation tax advisor engaged before closing is the most reliable way to minimize state-level exposure.

The IRS Audit Campaign

In February 2024, the IRS announced a dedicated audit campaign focused on business aircraft use by corporations, large partnerships, and high-net-worth individuals. The initiative targets three areas: proper application of the Section 274 deduction limits on entertainment and commuting, actual satisfaction of the Section 280F qualified business use thresholds, and correct reporting of personal-flight value as income to passengers and their guests.

Documentation standards have shifted accordingly. Flight logs should identify every passenger, the business purpose of each leg, and any personal portion of a trip. Reconstructing records after the fact was a risk before the campaign and is a bigger one now. Getting recordkeeping right from the start costs far less than the recapture, penalties, and interest that follow a failed audit.
