To minimize tax liability, small aircraft owners should consider depreciating their aircraft using the Modified Accelerated Cost Recovery System (MACRS). This method allows for a faster depreciation rate, with a 5-year recovery period for most aircraft.
The MACRS method can be broken down into several different depreciation schedules, each with its own unique recovery period. For example, the 200% declining balance method allows for a 20% depreciation deduction in the first year, while the 150% declining balance method allows for a 15% depreciation deduction in the first year.
Depreciating your aircraft using the MACRS method can result in significant tax savings over the life of the asset. By accelerating the depreciation, you can reduce your taxable income and lower your tax liability.
The IRS allows small aircraft owners to use the business use percentage to calculate their depreciation deduction. This percentage is based on the number of hours the aircraft is used for business purposes, and can range from 50% to 100%.

Depreciation Rules
Depreciation rules can be complex, but let's break it down simply. To understand aircraft depreciation rules, we must first explain the basics of depreciation for both IRS and GAAP.
You can only depreciate an aircraft if you use it for business. For bonus depreciation, you must use the aircraft at least 50% for business. If you purchase an aircraft for personal use that doesn't relate to business, you cannot depreciate it.
Depreciation basics are crucial to understand. Depreciation is the decrease in value of an asset over time, and it's a key factor in calculating business expenses.
You can depreciate an aircraft if you use it for business, but that's not all. The aircraft must be used at least 50% for business to qualify for bonus depreciation.

Depreciation Methods
Depreciation methods for small aircraft can be straightforward, but it's essential to understand the options available. The straight-line procedure is the most common and simplest method, suitable for many businesses.

There are also accelerated depreciation mechanisms that provide larger deductions early on, reducing taxes and income in the early years. This makes sense for businesses that need to maximize their deductions quickly.
You can use the Modified Accelerated Cost Recovery System (MACRS) method if your business use is 50% or more of flight time. This method is preferred by many owners because of its acceleration, allowing for most of the cost to be deducted within a few years.
Here's a breakdown of the MACRS schedule:
Straight-Line Method
The Straight-Line Method is the simplest and most common depreciation method. It's often used because it's easy to calculate.
To use the Straight-Line Method, you'll need to find the period of recovery. For MACRS, you can look this up in the tables provided by the IRS.
The formula for calculating depreciation is straightforward: ((book value – salvage value) / recovery period). This will give you the year's depreciation.

Double-Declining Balance Example

The Double-Declining Balance method is a popular depreciation method that can be complex, but don't worry, we'll break it down step by step.
You start by doubling the straight-line percentage, which in our example is 20%. This is calculated by multiplying the initial cost by the doubled percentage, resulting in a depreciation expense of $9 million in Year-1.
The book value decreases to $36 million after the first year, and in Year-2, the depreciation is 20% of $36 million, or $7.2 million.
As you can see, the book value continues to decrease, and the depreciation expense decreases each year until it reaches the salvage value of $5 million.
To quickly compute depreciation using the Double-Declining Balance method, you can use a calculator or simply repeat the process year after year, decreasing the book value and depreciation expense each time.
Recovery Periods
Recovery periods are a crucial aspect of depreciation, and they can be a bit confusing.

The Modified Accelerated Cost Recovery System (MACRS) specifies depreciation periods for all asset types, from as little as 3 to 30+ years.
For businesses, the Generally Accepted Accounting Principles (GAAP) govern the format and content of balance sheets, income statements, and other financial reports. Note that the asset's actual useable lifetime acts as the recovery period.
To determine the recovery period, you'll need to know the asset's MACRS and GAAP depreciation results. Each year, you must resolve the conflicts between these two results to ensure correct tax payments.
Here's a breakdown of the recovery periods for MACRS:
Keep in mind that the MACRS method is only available if business use is 50% or more of flight time.
Use Aircraft Advantageously
To use aircraft advantageously, you need to understand how depreciation works. You can only depreciate an aircraft if you use it for business.
You must use the aircraft at least 50% for business to qualify for bonus depreciation. This is a crucial factor in determining how you'll benefit from depreciation.

Depreciation Schedule
The depreciation schedule for your small aircraft is a crucial aspect to consider.
The MACRS aircraft depreciation schedule for Part 91 business aircraft is five years.
If you use your aircraft to transport freight or passengers, the MACRS recovery period is seven years.
The five-year depreciation schedule can help you recover the value of your aircraft more quickly.
This can be beneficial if you plan to upgrade your aircraft in the near future.
The seven-year recovery period, on the other hand, may be more suitable if you plan to keep your aircraft for an extended period.

Depreciation Systems

You can use the Modified Accelerated Cost Recovery System (MACRS) if your business use is 50% or more of flight time. This method is a common aircraft depreciation schedule.
The MACRS method is a front-loaded system that lets you deduct most of the cost of your aircraft within a few years. It's essential to know the value of your plane when you create a depreciation schedule.
Here's an example MACRS schedule with percentage deductions:
- Year 1 – 20%
- Year 2 – 32%
- Year 3 – 19%
- Year 4 – 12%
- Year 5 – 12%
- Year 6 – 5%
Alternatively, you can use the Alternative Depreciation System (ADS) if your business aircraft usage is under 50%. The ADS system takes the deduction equally (straight line) over a longer period, typically 12 years.
You must prove your business use even when you use ADS, and an increase in personal flights during the year may impact the depreciation schedule.
Modified Accelerated Cost Recovery System (MACRS)
The Modified Accelerated Cost Recovery System (MACRS) is a popular method for depreciating aircraft, and it's preferred by many owners because of its acceleration. This means you can deduct most of the cost of your aircraft within a few years.

To use MACRS, your business use must be 50% or more of flight time. This is a key requirement.
You can create a depreciation schedule using MACRS, and it's essential to know the value of your plane when you do. This will help you determine the depreciable value.
Here's a breakdown of the MACRS schedule:
- Year 1 – 20%
- Year 2 – 32%
- Year 3 – 19%
- Year 4 – 12%
- Year 5 – 12%
- Year 6 – 5%
The recovery period for MACRS can vary, but it's typically between 5 and 7 years. This means you'll need to recoup the initial cost of your aircraft over this period through tax deductions.
Alternative System
If your business aircraft usage is under 50%, you might want to consider the Alternative Depreciation System (ADS). This system allows you to take deductions equally over a longer period of 12 years.
To qualify for ADS, you must prove your business use, and keep in mind that an increase in personal flights during the year may impact the depreciation schedule.
You can use ADS even if your business use is under 50%, but your accountant will know more about the subject.
Here's an example of an ADS schedule:
The ADS schedule is a straight line depreciation, taking the deduction equally over the 12-year period.
Aircraft Bonus Qualification

To qualify for bonus depreciation, an aircraft must be used for business operations at least 50% of the time. This is a key factor in determining eligibility.
The use of an aircraft for business purposes has a direct impact on depreciation. If the aircraft is used primarily for personal reasons, it won't qualify for bonus depreciation.
The Tax Cuts and Jobs Act (TCJA) made significant changes to bonus depreciation rules. Prior to its enactment, first-year bonus depreciation was set at 50% for assets acquired between 2015 and 2017.
