Will Section 179D Expire Before You Upgrade

Authored by: Doug Gross — Partner, CPA, CGMA | Date Published: May 13, 2026

The ovens go on before the first customer walks in. The HVAC fights your kitchen heat all day. The dining room lights stay on through lunch, dinner, and every table turn in between. Running an independent pizzeria means running a building that never really rests, and that energy demand adds up fast, both on your utility bills and in the tax deductions you may not realize you qualify for.

A federal tax incentive built for high-energy commercial buildings like yours is on the verge of disappearing. It is called Section 179D, and understanding it before your next project or equipment purchase could make a meaningful difference in what you owe at the end of the year.

What Is the Section 179D Deduction and Why Should Pizzeria Owners Know About It?

Section 179D is a federal tax deduction for commercial building owners who invest in energy-saving improvements. It covers three main areas of your building:

Interior lighting systems
Heating, ventilation, and air conditioning (HVAC)
The building envelope, including insulation, windows, and exterior doors

To qualify, your improvements need to reduce your building’s annual energy costs by at least 25% compared to a standard reference point set by federal guidelines. The deduction grows as your energy savings grow, so more meaningful upgrades produce a larger deduction.

This applies to both new construction and renovation projects. If you are planning a remodel, expanding your footprint, or replacing aging systems, you may already be on the path to qualifying.

Why Do Pizzerias Qualify for This Deduction?

Restaurants are among the most energy-intensive commercial buildings in the country, and pizzerias sit near the top of that list. Foodservice buildings use roughly four times more energy per square foot than the average U.S. commercial building. Your deck or conveyor ovens run for 10 to 12 hours a day, your kitchen generates significant heat that your HVAC system fights against all day long, and your dining room lights stay on through every shift.

That relentless energy demand is exactly what the Section 179D tax deduction is designed to reward you for addressing. When you invest in improvements that bring those costs down, the federal government gives you a deduction for it at tax time.

The deduction also applies to the building itself, not just individual pieces of equipment. That distinction matters for owners who are expanding, renovating their dining room, or upgrading insulation as part of a larger build-out.

What Equipment and Upgrades Qualify?

The upgrades that qualify are likely the ones you have already been thinking about for practical reasons. If you’re curious about what appliance quality for energy tax credit, the answer is that many modern, high-performing appliances can help you qualify for tax credits for energy efficiency. Reducing utility bills and improving the comfort of your dining room are benefits on their own. Here is what can count toward the deduction:

HVAC

High-efficiency commercial HVAC units replacing older systems.
Upgraded kitchen ventilation and exhaust hood systems.
Programmable thermostats and energy management controls.

Lighting

LED replacements for your dining room, bar, restrooms, and exterior.
Occupancy sensors and dimming controls for less-used spaces.
Full LED fixture replacements were done as part of a renovation.

Building Envelope

Added or upgraded wall and roof insulation.
Energy-saving windows and exterior doors.
Building sealing improvements that reduce heating and cooling loss.

A coordinated renovation that addresses multiple systems at once tends to produce a larger deduction than a single isolated swap, since the deduction is based on the building’s overall energy performance.

How Much Can a Pizzeria Deduct?

The deduction ranges from $0.58 to $5.81 per square foot of your building, depending on how much energy your improvements save and whether your project meets federal prevailing wage and apprenticeship requirements during construction.

Here is a simplified way to look at the ranges:

Base rate (no wage requirements): $0.58 to $1.16 per square foot, scaling up with the percentage of energy savings achieved above the 25% threshold
Higher rate (with prevailing wage compliance): $2.90 to $5.81 per square foot

To put those numbers in real terms for a pizzeria owner:

A 2,500 sq. ft. location at $1.00/sq. ft. = $2,500 deduction
A 4,000 sq. ft. location at $2.50/sq. ft. = $10,000 deduction
A 6,000 sq. ft. location at $5.81/sq. ft. = $34,860 deduction
Multiple locations multiply these numbers across your entire portfolio.

Can You Stack Section 179D With Other Tax Strategies?

Yes, and this is where working with a CPA who knows your industry pays off. The Section 179D energy efficiency tax deduction does not have to stand alone. It can be part of a coordinated tax approach that accelerates deductions and reduces your overall liability in the year a project is completed.

Three strategies that work well together:

Section 179D (Building Energy Efficiency): The deduction covered in this post applied to qualifying lighting, HVAC, and building envelope improvements.
Section 179 (Equipment Expensing): Allows you to immediately deduct the full cost of qualifying equipment purchases, such as a new commercial oven or refrigeration unit, rather than writing it off gradually over many years.
Cost Segregation: An engineering-based study that reclassifies components of your building, including flooring, counters, electrical, and plumbing, into shorter depreciation schedules, accelerating the deductions you take in early years.

When a renovation is planned with all three strategies in mind, the combined impact on your tax liability can be substantial. This is especially true for owners who just completed a new build, purchased a building, or are in the middle of a major renovation.

Does Section 179D Work Differently for New Construction vs. an Existing Location?

Both paths qualify, and each has its own approach.

For new construction, the entire building is evaluated for energy performance. If you are building a new location, your architect and contractor should be aware of Section 179D early in the planning process so the design can target the required energy savings from the start.

For an existing pizzeria, the path forward is updating your current building in place rather than starting fresh. The IRS provides an alternative measurement pathway for existing buildings that evaluates actual improvements in energy use over time, rather than requiring upfront modeling projections. For a pizzeria that has been operating in the same building for several years, this opens the door to deductions for HVAC replacements, LED upgrades, and insulation work you may have already been considering.

For multi-location owners, each building is evaluated separately. That means the deduction can be applied to qualifying improvements across your entire portfolio, one location at a time.

What Documentation Is Required to Claim This Deduction?

Section 179D requires third-party certification by a licensed engineer or architect to verify that your improvements meet the required energy-savings thresholds. Your CPA coordinates this process with your engineer and contractor.

The documentation process generally includes:

An energy study performed by a qualified professional confirms that the required savings were achieved.
A signed certification letter documenting those results.
Construction records confirming what was installed, when, and where.
IRS Form 7205 submitted with your tax return.

The earlier you bring your tax advisor into the conversation, ideally before you finalize the scope of your renovation, the easier it is to position your project for the best possible outcome.

When Does Section 179D Expire, and What Does That Mean for Your Business?

The federal legislation passed last year set a firm termination date: Section 179D will not apply to any project that begins construction after June 30, 2026.

The key phrase is “begins construction.” Your project does not need to be finished by that date. It needs to start. That means:

If you are planning an HVAC replacement this summer, moving up your timeline by a few weeks could be the difference between capturing this deduction and missing it entirely.
If you are finalizing plans for a second location, getting construction started before the deadline locks in your eligibility
If you have been on the fence about a renovation, the expiration of this deduction is a real financial reason to make a decision now

There is no indication that Section 179D will be renewed after it expires. Planning based on the assumption that it will return could cost you significantly.

Are You Capturing Every Tax Advantage Your Pizzeria Has Earned?

At MBE CPAs, we take the time to dig into the details with every client we work with. If you are planning a renovation, an equipment upgrade, or a new location, let’s connect before the June 30 deadline arrives.

Energy-efficient operations do not just reduce taxes. They lower your monthly utility bills and put more money back into your business over the long run. Protecting that bottom line, though, goes beyond your utility costs. Are you sure you are capturing every dollar of the FICA tip credit? Most pizzeria owners we work with during a tax review discover they have been leaving $15,000 to $25,000 on the table annually through improper tip reporting.
