Depreciation deductions can be a powerful tool for taxpayers, but there are limits to how much you can deduct. The IRS sets these limits to prevent abuse of the system.
The Modified Accelerated Cost Recovery System (MACRS) is used to calculate depreciation for most assets, but it has a maximum recovery period of 20 years for most property. This means that you can only depreciate an asset for a certain number of years before you can no longer claim a depreciation deduction.
Taxpayers can also only deduct a certain percentage of the cost of an asset in the first year, known as the "bonus depreciation." This is a one-time deduction that allows you to deduct a larger portion of the asset's cost in the first year, but it's limited to $1 million for most taxpayers.
The IRS also has rules governing the use of Section 179 deductions, which allow taxpayers to deduct the full cost of certain assets in the first year. However, the maximum deduction is limited to $1 million, and the deduction is phased out as the cost of the assets exceeds $2.5 million.

Tax Implications
The IRS limits the depreciation deduction for luxury cars, which are defined as vehicles with a fair market value exceeding $15,000.
This limit applies to vehicles with a gross vehicle weight rating (GVWR) over 6,000 pounds.
Business use of a luxury car can be depreciated at a rate of 20% per year, but only up to a maximum of $15,000.
Rev. Proc. 2014-21
Rev. Proc. 2014-21 is a significant IRS document that outlines the procedures for determining the tax implications of certain transactions. It's a lengthy document, but one key takeaway is that it establishes the use of Form 8275, Disclosure Statement, to disclose certain positions.
The document specifically addresses the use of Form 8275 to disclose positions that are not clearly disclosed on the return. This is particularly important for taxpayers who engage in complex transactions.
The IRS requires taxpayers to disclose certain positions on Form 8275 if they are not clearly disclosed on the return. This includes positions that are not clearly disclosed on the return, such as those related to the valuation of assets or the characterization of income.
Taxpayers who fail to disclose certain positions on Form 8275 may be subject to penalties.

State Implications

State Implications are crucial to consider when planning your tax strategy. Some states conform to the federal Internal Revenue Code, while others have different rules.
If you're planning to take advantage of depreciation deductions, you need to think about both federal and state depreciation bonus rules. This is especially important if you're placing qualifying property in service before year end.
Some states don't allow bonus depreciation, so you need to check their rules before making any decisions. This can affect the amount of depreciation deductions you can claim.
You should consider state implications in your tax planning, especially if you're planning on placing qualifying property in service before year end. This will help you make the most of your depreciation deductions.

Tax Planning for Multi-Pass-Through Business Owners
As a business owner with multiple pass-through businesses, you've got a unique tax situation on your hands. You're likely familiar with the benefits of pass-through entities like S corporations, limited liability companies (LLCs), and partnerships.
If you own two S corporations, for instance, electing the maximum Section 179 deduction in 2023 means each entity can pass down $1,160,000 of depreciation deductions to your individual federal income tax return.
This can create a double dip in deductions, but be aware that any excess above $1,160,000 is lost and can't be carried forward to future tax years.
Careful planning is essential to make the most of your Section 179 deductions.

Deductions for Heavy SUVs

Heavy SUVs can qualify for significant tax deductions under Section 179, but there are some specific requirements to keep in mind.
The maximum Section 179 depreciation deduction for heavy SUVs is $28,900 for the 2023 tax year, and it increases to $30,500 for the 2024 tax year.
To qualify for these deductions, the vehicle must be used over 50% for business purposes, or else the business-use percentage of the vehicle's cost will need to be depreciated using the straight-line method.
This means it'll take six tax years to fully depreciate the vehicle if it's not used primarily for business.
If you're considering buying a heavy SUV for business use, be sure to keep track of how you're using it to ensure you qualify for the maximum Section 179 deduction.

Bonus Depreciation
Bonus Depreciation is a powerful tax deduction that can help businesses reduce their taxable income. It's an additional first-year depreciation allowance that allows business taxpayers to deduct extra depreciation for the cost of qualifying business property.

The IRS now allows bonus depreciation on both new and used equipment, as long as the asset was not previously used by the purchaser or received from a related party. This is a significant change from the past, when bonus depreciation was only available for new equipment.
The bonus depreciation percentage has been ramping down over the years, currently standing at 60% for 2024. It will decrease to 40% in 2025, 20% in 2026, and eventually reach 0% in 2027.
To qualify for bonus depreciation, the property must have a recovery period of 20 years or less, which includes vehicles, equipment, furniture and fixtures, machinery, computer software, and certain qualified improvement property. This means that businesses can claim bonus depreciation on a wide range of assets, not just heavy equipment.
Here's a breakdown of the bonus depreciation percentage for each year:
By taking advantage of bonus depreciation, businesses can reduce their taxable income and save money on taxes. It's an important consideration for any business looking to invest in new equipment or property.
Calculate Savings

Calculating your potential savings is a crucial step in understanding the impact of Section 179 and bonus depreciation on your business tax deductions.
The cost of equipment can be a significant expense, but with Section 179 deduction, you could save up to $1,220,000.
This means that the total first year deduction could be as high as $2,430,400, which includes the Section 179 deduction, bonus depreciation deduction, and standard first year depreciation.
The cash savings on purchase, assuming a 21% C-Corp tax bracket, could be around $510,384.
This translates to a lowered cost of equipment, after tax savings, of $2,489,616, making it a more affordable option for your business.

Combining Deductions

You can use both Section 179 and bonus depreciation deductions together to maximize benefits. This combination is particularly useful in situations where the stand-alone benefits of Section 179 are limited.
The Section 179 expense limit and phase-out threshold are now permanent, but bonus depreciation now covers new and used equipment, making Section 179 benefits less substantial on their own. This is especially true for taxpayers without specific business circumstances.
The bonus depreciation percentage is set at 60% for 2024, creating a strong incentive for businesses to make near-term purchases. This is a short-term consistency with the bonus depreciation limit, which will ramp down further in subsequent years.
Here are the key takeaways:
- Section 179 benefits are limited to specific business circumstances.
- Bonus depreciation covers new and used equipment, making Section 179 benefits less substantial on their own.
- Bonus depreciation percentage is 60% for 2024, creating a strong incentive for near-term purchases.
How Can Deductions Work Together
Deductions can be a powerful tool for businesses to reduce their taxable income and improve cash flow. By combining different types of deductions, businesses can maximize their tax savings.
Businesses can leverage both bonus depreciation and Section 179 in the same tax year to achieve this. According to the IRS rules, most businesses must apply Section 179 first, which allows them to write off the full purchase price of eligible assets up to a certain limit.

Here's a step-by-step guide on how to combine these two deductions:
- Apply Section 179 first to write off the full purchase price of eligible assets up to the limit.
- After reaching the Section 179 limit, claim bonus depreciation on the remaining cost of eligible assets.
This strategy allows businesses to maximize their deductions in the first year, providing significant tax relief and improving cash flow.
Combining Bonus Depreciation and 179
Businesses can leverage both bonus depreciation and Section 179 in the same tax year to maximize their tax savings. This strategy is particularly beneficial for companies with significant equipment purchases.
The IRS requires most businesses to apply Section 179 first, so use it to write off the full purchase price of eligible assets up to the limit of $1,220,000 in 2024. This limit is a permanent part of the tax code.
After reaching the Section 179 limit, apply bonus depreciation to the remaining cost of eligible assets. The bonus depreciation percentage is set at 60% for 2024, making it an attractive option for businesses looking to make near-term purchases.
Businesses can't create a tax loss with Section 179 initial year expensing, but bonus depreciation has no such limitations. This means that it's possible to reduce your company's taxable income to zero using Section 179 and then use bonus depreciation on any depreciable assets to create a tax loss that can be carried forward to a future tax year.
To illustrate this, consider the following:
Note that equipment investments exceeding $4,270,000 are not eligible for any Section 179 deduction, but may still be eligible for bonus depreciation.
