To depreciate a vehicle for business and tax purposes, you'll need to choose the correct method for your company. The Modified Accelerated Cost Recovery System (MACRS) is the most commonly used method.

You can use the MACRS method to depreciate a vehicle over a period of 5 years, which is the standard depreciation period for most business vehicles. This means you can claim a larger depreciation deduction in the early years of ownership.

The annual depreciation amount is determined by the vehicle's cost and the number of years remaining in the depreciation period. For example, if you purchase a vehicle for $20,000, the annual depreciation amount would be $4,000 in the first year and $3,200 in the second year.

Keep in mind that the vehicle must be used at least 50% of the time for business purposes to qualify for depreciation.

Depreciation Basics

Depreciation is a natural part of car ownership, and it's essential to understand how it works. The value of your car decreases the minute you purchase it, dropping to 91% of its initial market value.

The depreciation rate is significant, with the car's value decreasing to 81% of its initial value after just one year. This means that the moment you drive your new car off the lot, its value has already taken a hit.

Here are the key depreciation milestones:

  • After one year: 81% of initial value
  • After two years: 69% of initial value
  • After three years: 58% of initial value
  • After four years: 49% of initial value
  • After five years: 40% of initial value

It's worth noting that each brand and model loses its value at a slightly different rate, but this calculator provides a general idea of what to expect.

What Is Depreciation?

Depreciation is a reduction in the value of an asset over time, due to wear and tear, obsolescence, or other factors.

The most common type of depreciation is straight-line depreciation, where the asset's value is reduced by a fixed amount each year.

Depreciation can be calculated using various methods, including the straight-line method, declining balance method, and units-of-production method.

The straight-line method is the simplest and most common method, where the asset's value is reduced by an equal amount each year.

Depreciation is a real expense that affects a business's financial statements, and it's not just a theoretical concept.

A business can depreciate assets such as buildings, equipment, and vehicles, which have a limited useful life.

Depreciation is also a key factor in determining a business's taxable income and tax liability.

Value Decrease

The value of a car decreases rapidly after purchase. In fact, the minute you buy a car, its value drops to 91% of the initial market value. This is because the perception of the next prospective buyer changes from "new car" to "used car".

The value of a car continues to decrease year after year, with significant drops in the first few years. After one year, the value of a car decreases to 81% of the initial value, and after five years, it decreases to 40% of the initial value.

The rate at which a car depreciates depends on various factors, including the type of car, its condition upon resale, and whether there will be a new model coming out soon. Some cars, like the Jeep Wrangler Unlimited and Wrangler, depreciate significantly less than others, with an average 5-year depreciation rate of just 27.3%.

1Jeep Wrangler Unlimited27.3%
2Jeep Wrangler27.3%
3Toyota Tacoma29.5%

The diminishing value method is another way to calculate the depreciation of a car, but it's a bit more complex and requires calculating the depreciation against the new value of the car.

Tax Implications

You can deduct vehicle depreciation on taxes if you use a vehicle for business purposes at least 50% of the time. This is because tax depreciation is the recovery of the cost of property, such as a business vehicle, over a number of years.

To qualify, your vehicle must be used within the United States, not used for hire, and you must be the owner claiming the deductions. If you use a vehicle solely for business purposes, you may deduct its entire cost of ownership and operation, subject to limits.

However, if you use the vehicle for both business and personal purposes, you can only deduct the cost of its business use. This means you'll need to keep track of the percentage of business use to accurately calculate the deduction.

There are two primary methods for calculating vehicle depreciation for taxes: MACRS (declining balance method) and straight-line depreciation. You can choose the method that best suits your needs, but be aware that each has its own set of rules and limitations.

To make the process easier, consider using comprehensive depreciation software, such as Thomson Reuters Fixed Assets CS. This can help you work smarter and faster with unlimited depreciation treatments and automatic federal and state depreciation calculations.

Here's a summary of the requirements for deducting vehicle depreciation on taxes:

  • Vehicle used for business purposes at least 50% of the time
  • Used within the United States
  • Not used for hire
  • Owner claiming the deductions
  • Keep track of business use percentage for mixed-use vehicles

Depreciation Methods

There are several methods to calculate the depreciation of a vehicle, each with its own formula and requirements.

The Prime Cost Method calculates the depreciation through the years at a fixed rate, estimating how much value is lost per year.

To calculate the lost value, you multiply the total cost of the car by the number of days owned divided by 365, and then by the effective life in years. For example, if you bought a brand new car for $45,000 with an effective value of 10 years, the lost value would be $4,500.

The Diminishing Value Method calculates the diminished value of a car in a single year, taking into account the new value of the car. This method requires subtracting the lost value from the original value of the car each year.

In the Diminishing Value Method, the lost value is calculated by multiplying the total value of the car by the number of days owned divided by 365, and then by 200% divided by the effective life in years. For example, if you bought a brand new car for $50,000 with an effective value of 10 years, the lost value would be $10,000 in the first year.

Straight-line depreciation is used in certain situations, such as when the standard mileage rate is used in the year the client placed the car in service and then changed to the actual expense method in a later year. In this case, straight-line depreciation must be used over the rest of the useful life of the car.

Straight-Line depreciation is a method that's required in certain situations. If you switch from the standard mileage rate to the actual expense method after the car is in service, you'll need to use straight-line depreciation for the rest of its useful life.

The depreciable basis is divided evenly across the vehicle's useful life. This means that if the business use of the vehicle is less than 50%, you'll have to use straight-line depreciation.

You can't deduct more depreciation than allowed by the limits.

To calculate straight-line depreciation, divide the depreciable basis by the number of years in the vehicle's useful life.

Actual Expense Method

The Actual Expense Method is a straightforward way to calculate depreciation. It involves tracking the actual expenses related to a business asset, such as maintenance, repairs, and replacement parts.

These expenses are then deducted from the asset's initial value over time, allowing businesses to accurately reflect their depreciation on their financial statements. The initial value of the asset can vary depending on its purchase price or fair market value.

In the example of a company that purchases a new truck for $50,000, the Actual Expense Method would require them to track and deduct the actual expenses related to the truck, such as fuel, maintenance, and repairs, from the initial value of $50,000. This approach can be more accurate than other methods, as it takes into account the actual costs of owning and operating the asset.

Prime Cost Method

The Prime Cost Method is a straightforward way to calculate depreciation. It estimates the value lost per year by dividing the total cost of the asset by its effective life.

You can use this method to estimate the value lost per year, which is calculated by multiplying the total cost of the asset by the number of days owned and then dividing by the effective life in years.

For example, if you bought a brand new car for $45,000 and it has an effective life of 10 years, the value lost per year would be $4,500. This is calculated by multiplying the total cost by the number of days owned and then dividing by the effective life in years.

To continue using this method, you'll subtract the same lost value every year against the total cost. This helps you track the decline in value over time.

The diminishing value method is a bit more complex than the prime cost method. It calculates the diminished value of a car in a single year, taking into account the new value of the car after depreciation.

To calculate the lost value using this method, you multiply the total value of the car by the number of days owned divided by 365, and then by 200% divided by the effective life in years.

For example, let's say you bought a brand new car for $50,000 and owned it for a year with an effective value of 10 years. The lost value would be $10,000.

When calculating for the second year, you subtract the lost value from the original value of the car and then follow the formula again. This process continues for each subsequent year.

The diminishing value method takes into account the fact that the value of a car decreases over time, with the value dropping to 91% of the initial market value the minute you purchase it.

Here's a rough estimate of how the value of a car decreases over time:

  • After a year, the car's value decreases to 81% of the initial value.
  • After two years, the car's value decreases to 69% of the initial value.
  • After three years, the car's value decreases to 58% of the initial value.
  • After four years, the car's value decreases to 49% of the initial value.
  • After five years, the car's value decreases to 40% of the initial value.

Mileage Rate

The mileage rate is a significant factor in depreciation. The business standard mileage rate for 2023 is 65.5 cents per mile, a 3-cent increase from the 62.5-cent rate in the second half of 2022.

To put this into perspective, using the standard mileage rate can be a convenient alternative to calculating actual expenses. This rate can be used instead of determining fixed and variable expenses that are deductible as business expenses.

The higher the mileage on a car, the less value it will retain. More kilometres on a car mean it's been used more and experiences more wear and tear compared to a car with fewer mileage.

A car with high mileage will likely depreciate faster than one with lower mileage. This is because high mileage indicates more use and wear on the vehicle.
