Learn how Bonus Depreciation and 179D Deductions can significantly reduce costs for commercial lighting upgrades through tax incentives.


Upgrading your commercial lighting? Two key tax incentives - Bonus Depreciation and 179D Deductions - can help you save big on costs. Here's what you need to know:
Key Differences:
Timing matters: Bonus Depreciation phases out after 2027, while 179D remains permanent. Combining both can maximize savings. Let’s explore how these incentives work and how to decide which one fits your project.
Bonus depreciation offers significant tax advantages for businesses undertaking commercial lighting upgrades. For property placed in service during 2024, businesses can immediately deduct 60% of the asset's cost. This approach eliminates the need to spread deductions over several years. Even more enticing, recent legislative updates have made 100% bonus depreciation permanent for qualified property placed in service starting in 2025. This broader applicability provides businesses with more options for various lighting projects.
One major perk? Unlike Section 179 deductions, bonus depreciation has no annual deduction cap. For example, if a company invests $500,000 in LED lighting, it can claim a $300,000 deduction in 2024 under the 60% rate.
Another advantage is that bonus depreciation applies to both new and used properties, including LED fixtures and qualified improvement property (QIP). There are no taxable income restrictions, meaning businesses can use this benefit to create or increase a net operating loss. QIP, which encompasses interior improvements to non-residential buildings, makes bonus depreciation particularly appealing for large-scale lighting upgrades in offices, warehouses, or retail spaces.
These features are game-changers for planning lighting projects, as you'll see in the next section.
Bonus depreciation simplifies tax planning for a wide array of lighting assets. LED fixtures, lighting controls, and QIP all qualify, as long as they have a recovery period of 20 years or less.
Here’s a practical example: If a business spends $100,000 on LED lighting upgrades in 2024, it can deduct $60,000 (60%) that same year. By 2025, when the bonus depreciation rate increases to 100%, the full $100,000 could be deducted upfront. This immediate deduction can significantly reduce taxable income and lower the overall tax burden in the first year.
Businesses can also combine Section 179 deductions with bonus depreciation in the same tax year. In this scenario, Section 179 is applied first to eligible assets up to its annual limit, while bonus depreciation covers the remaining depreciable basis - unless the taxpayer opts out.
To claim these benefits, businesses must carefully document their deductions. Bonus depreciation is reported on IRS Form 4562, "Depreciation and Amortization", for the tax year in which the property is placed in service. If a business decides not to use bonus depreciation, it must attach an opt-out statement to its tax return.
Luminate Lighting Group supports clients through every step of this process. They identify eligible lighting assets, provide the necessary IRS documentation, and collaborate with tax professionals to ensure businesses maximize their bonus depreciation benefits. With their expertise in energy-efficient LED retrofits and custom lighting design, Luminate Lighting Group helps clients meet energy code requirements and qualify for tax incentives. This approach not only reduces upfront tax liabilities but also unlocks additional savings through available utility rebates, making lighting projects more cost-effective and impactful.
Section 179D is a federal tax incentive designed to reward energy-efficient building upgrades. Unlike bonus depreciation, which has a broader scope, 179D specifically focuses on energy performance improvements. The Consolidated Appropriations Act of 2021 made Section 179D a permanent part of the tax code, and the Inflation Reduction Act of 2022 expanded its benefits and adjusted eligibility criteria. These legislative updates highlight the government’s dedication to encouraging energy-efficient upgrades in commercial buildings. This creates an ideal framework for understanding the financial impact of 179D deductions, particularly for lighting projects.
To qualify for 179D deductions on lighting retrofits, projects must adhere to ASHRAE 90.1 benchmarks. The lighting system must demonstrate a substantial reduction in energy use compared to a reference building, and third-party certification is required. Eligible properties include commercial buildings and government facilities. For government-owned buildings, the deduction can be assigned to the designer - such as an engineer, architect, or lighting contractor - responsible for implementing the energy-efficient improvements.
Projects must be placed in service during the tax year for eligibility, and detailed documentation is essential. This includes energy models, project specifications, proof of installation, and certification from a licensed engineer. These records need to be submitted with the tax return to validate the deduction claim.
Meeting the eligibility criteria unlocks significant financial benefits. As of 2023, the maximum deduction is $5.00 per square foot for projects achieving at least a 50% reduction in energy and power costs compared to a reference building. Partial deductions are available for lower levels of energy savings, making the incentive accessible to a wide range of projects. The amount of the deduction is directly tied to the building’s size and the energy savings achieved. For example, a 100,000-square-foot warehouse that meets maximum efficiency standards could qualify for a $500,000 deduction.
Beyond tax savings, these deductions shorten the payback period for lighting investments and improve cash flow by lowering the after-tax cost of energy-efficient upgrades.

Luminate Lighting Group simplifies the often-complicated process of qualifying for 179D deductions by offering comprehensive support services. Their team performs energy audits to identify inefficiencies and calculates the energy savings that proposed lighting upgrades would deliver.

By combining energy audits, tailored lighting designs, and detailed documentation support, they enable clients to maximize both energy savings and tax benefits while remaining fully compliant with federal regulations.
Understanding the differences between bonus depreciation and 179D deductions is essential for businesses looking to make smart decisions about lighting investments. While both incentives aim to lower taxable income, they follow different rules and serve unique purposes in tax planning. The table below highlights the main contrasts between these two tax incentives.
| Feature | Bonus Depreciation | 179D Deductions |
|---|---|---|
| 2024 Deduction Rate | 60% of asset cost | Up to $5.00 per square foot |
| Annual Dollar Limit | No limit | Based on building size and energy savings |
| Eligible Assets | Lighting equipment with a recovery period of 20 years or less | Energy-efficient lighting systems in commercial buildings |
| Income Limitation | None – can create a net operating loss | None |
| Certification Required | No special certification needed (standard tax return election) | Third-party certification required |
| Documentation | Standard tax return election | Detailed energy models, specifications, and compliance documentation |
| Asset Selection | Applies to all assets in the same class | Project-specific based on energy performance |
| Phase-out Schedule | Decreases by 20% annually until elimination in 2027 | Permanent incentive with inflation adjustments |
| Primary Focus | Immediate tax relief on capital investments | Rewarding energy efficiency improvements |
This breakdown not only highlights the benefits but also illustrates the filing requirements for each incentive. For example, bonus depreciation allows businesses to claim substantial deductions for significant lighting purchases with minimal paperwork. On the other hand, 179D deductions are tied to energy efficiency and building size - offering up to $500,000 in deductions for a 100,000-square-foot facility that meets maximum efficiency standards. While bonus depreciation only requires a standard election on the tax return, 179D deductions demand third-party certification, energy modeling, and detailed documentation to verify compliance.
Bonus depreciation is an excellent choice for businesses seeking immediate tax relief, especially those with large lighting equipment purchases and high taxable income. It’s particularly advantageous for companies looking to accelerate depreciation and offset their current tax liability.
In contrast, 179D deductions are better suited for large-scale, energy-efficient lighting retrofits in commercial properties. These deductions are ideal for projects involving significant square footage and measurable energy savings, making them a go-to option for businesses prioritizing sustainability and long-term value.
Timing also plays a crucial role in deciding between these incentives. Bonus depreciation is gradually phasing out, dropping from 80% in 2023 to 60% in 2024, and will continue to decrease by 20% each year until it ends in 2027. Meanwhile, 179D deductions remain a permanent option with inflation adjustments, offering stability for future planning.
For straightforward lighting purchases where energy efficiency isn’t a primary concern, bonus depreciation provides simplicity and quick financial benefits. On the other hand, 179D deductions offer greater long-term savings for projects that focus on energy efficiency, despite their more complex documentation and certification process. By understanding these differences, businesses can strategically plan their investments to maximize tax benefits and align with their financial goals.
Strategic planning can transform lighting upgrades into powerful tax-saving opportunities by combining different incentives and timing investments effectively. With bonus depreciation set to decrease in the coming years and 179D deductions offering long-term advantages, businesses need a well-thought-out approach to navigate these decisions.
Several key factors determine the best tax incentives for a business, including project cost and business income levels. For example, Section 179 deductions are capped by your annual taxable business income, which means they’re less useful for companies with low or negative earnings.
Bonus depreciation, on the other hand, provides a solution for businesses facing these limitations. Unlike Section 179, bonus depreciation has no income or spending limits and can even create or increase a net operating loss. For instance, a dental practice that invests $1,000,000 might use Section 179 for $250,000, bonus depreciation for $750,000, and secure a 179D deduction to achieve a full first-year deduction.
Timing also plays a critical role. With bonus depreciation scheduled to phase out in the coming years, delaying projects could mean losing out on substantial deductions.
Energy efficiency requirements further shape the decision-making process. To qualify for 179D deductions, projects must meet specific energy efficiency standards and obtain third-party certification.
The sequence of applying deductions can also impact overall savings. Tax professionals often recommend applying Section 179 first, followed by bonus depreciation, and then regular depreciation.
Given the complexity of these factors, professional guidance is often necessary to ensure businesses maximize their tax benefits.
Navigating these intricate decisions requires the expertise of both lighting specialists and tax advisors. Combining technical knowledge of lighting systems with an understanding of tax regulations is essential for avoiding errors and capturing all available incentives.
Luminate Lighting Group offers a strong foundation for this process. Their services start with free on-site audits that identify energy inefficiencies and potential improvements. These evaluations document current lighting setups, estimate energy savings, and design tailored LED retrofit solutions that meet 179D requirements.
Their comprehensive approach includes lighting design, installation, permitting, and rebate submissions, all while ensuring compliance with energy codes through licensed electricians. This attention to detail is critical, as 179D deductions require proper documentation and third-party certification.
Tax advisors play a complementary role by structuring purchases to maximize available incentives and ensuring compliance with IRS rules. Common mistakes - such as failing to document asset placement dates, exceeding Section 179 limits, or neglecting 179D certification - can be avoided with expert help. Early planning and accurate record-keeping are key to sidestepping these pitfalls.
Coordination between lighting and tax professionals becomes even more important for larger projects. Luminate Lighting Group’s utility rebate and incentive support simplifies the process by pre-qualifying rebates, handling paperwork, and ensuring timely reimbursements. These rebates can influence the basis for calculating depreciation deductions, making seamless integration with tax planning essential.
Post-installation support is another critical element. Luminate Lighting Group provides system testing, warranty details, and maintenance guidance to ensure long-term energy savings. This ongoing support is vital because 179D deductions depend on actual energy performance, not just initial projections.
Selecting the best tax incentive for your lighting project depends on your business's financial needs and the scale of the project. For example, bonus depreciation allows for 100% deductions on qualifying assets placed in service through 2025, making it a strong choice for larger projects. On the other hand, 179D deductions are specifically designed to reward energy-efficient retrofits, offering significant tax savings regardless of income. Each of these options requires a customized approach tailored to your specific situation.
The size of your project and your taxable income play a key role in determining the most effective combination of incentives. For smaller projects under $2.5 million, a layered strategy can help maximize deductions if there’s sufficient taxable income. Meanwhile, bonus depreciation is particularly effective for larger investments, as it can even create a net operating loss, which businesses can strategically leverage. For projects focused on energy efficiency, 179D deductions are a great complement, as they provide rewards based on measurable improvements in energy performance.
To maximize upfront tax benefits, a sequential strategy often works best. For instance, businesses can first apply Section 179, then use bonus depreciation, and finally claim 179D deductions. This approach not only maximizes immediate savings but also supports long-term energy efficiency goals.
Timing is another critical factor. Placing assets in service before the end of the year ensures eligibility for current bonus depreciation benefits. Additionally, recent legislative updates have enhanced the 179D provisions, making them even more attractive for commercial lighting projects.
Navigating these choices can be complex, but Luminate Lighting Group simplifies the process. They provide complimentary assessments to identify inefficiencies and design LED retrofits that qualify for 179D deductions. Their end-to-end service covers everything from design and installation to permits and rebate submissions, reducing the risk of compliance errors that could jeopardize valuable tax incentives.
"The Luminate team retrofitted the lighting in a few of our commercial properties, and I couldn't be more pleased with the quality of the work, the value they provided, and the level of service they delivered. I can definitely recommend their work." – C. Bennett, Building Owner
Luminate also offers utility rebate and incentive support, pre-qualifying rebates and managing the paperwork to ensure timely reimbursements. These rebates further enhance the return on investment for lighting projects. Their expertise in energy code compliance ensures businesses capture all eligible financial benefits while achieving superior lighting and energy savings.
Achieving success with lighting tax incentives requires blending technical know-how with strategic tax planning. Luminate Lighting Group’s turnkey solutions provide the groundwork for compliance and performance, while tax professionals can help structure deductions to deliver the best results. This collaboration ensures businesses avoid common pitfalls and fully capitalize on the tax savings available through today’s incentive programs. Together, these strategies align perfectly with broader goals for energy-efficient lighting upgrades.
Bonus Depreciation and the 179D Deduction are both useful tax incentives, but they cater to different needs when it comes to commercial lighting projects. Bonus Depreciation lets businesses write off a significant portion of the cost of eligible assets - like new lighting systems - in the year they’re installed. This provides an opportunity to lower upfront tax obligations. Meanwhile, the 179D Deduction is designed to reward energy-efficient building improvements, including lighting upgrades, as long as they meet specific energy code standards.
Choosing the right option depends on several factors, such as the scale of your lighting upgrade, your business's current tax situation, and whether your project qualifies under the 179D energy efficiency guidelines. Working with a tax professional or a specialized firm like Luminate Lighting Group can help ensure you maximize your tax benefits while aligning with your energy efficiency and sustainability objectives.
To claim the 179D tax deduction, you'll need to gather specific documentation and certifications to prove your project's eligibility. This includes an energy analysis performed by a qualified professional, like a licensed engineer or contractor, to confirm your building meets the energy efficiency standards set by the tax code.
You'll also need a signed certification from the professional verifying compliance with the 179D requirements. Keep detailed records of your lighting project - such as invoices, project descriptions, and energy modeling reports - as these might be necessary for certification or if you're audited. Having thorough documentation can make the entire process much smoother.
Yes, you can use both Bonus Depreciation and the 179D Deduction in the same tax year, but each serves a different purpose and follows its own set of rules. Bonus Depreciation lets you deduct a large portion of the cost for qualifying assets - like lighting equipment - in the year they’re put into use. Meanwhile, the 179D Deduction is aimed at rewarding energy-efficient building upgrades, such as LED retrofits, by offering deductions based on the energy savings achieved.
Combining these incentives can significantly boost your tax savings. However, it’s crucial to work with a tax professional to navigate IRS regulations and understand how these programs apply to your specific project. With careful planning, you can make the most of these benefits while meeting both your financial and energy-efficiency objectives.
