Retail Owners: Last Chance for Huge Tax Savings Before 179D Ends in 2026!

Marc Perlof • September 22, 2025

Hey, Retail Real Estate Rockstars!


Property owners could lose tens of thousands in
federal tax savings on building upgrades starting July 2026. The Big Beautiful Law (H.R. 1) ends the Energy Tax Deduction for Commercial Buildings (§ 179D). If you’ve been counting on tax savings for energy upgrades like HVAC, lighting, or windows, here’s what you need to know to plan smart.


What § 179D Gave You vs. What’s Changing

Before, § 179D let building owners (including retail landlords) take tax deductions for energy-saving improvements, things like LED lighting, efficient HVAC systems, and better insulation or windows. These deductions often meant real money saved when making upgrades.
Now, under H.R. 1:

  • Starting July 1, 2026, new construction or upgrade projects will no longer qualify for § 179D deductions¹.
  • That means no tax savings for HVAC, lighting, or other energy upgrades if work begins after June 30, 2026.
  • Projects already started before that date may still qualify.


Key Points

  • The energy tax deduction (§ 179D) ends for projects that begin after June 30, 2026¹.
  • Retail owners planning upgrades should move quickly to use the benefit before it disappears.
  • Budgets, return on investment (ROI), and financial models need to be updated for this change.


Data You Should Know

  • § 179D savings were often measured in dollars per square foot of upgrades across lighting, HVAC, and building envelope systems².
  • The repeal impacts all commercial building owners starting new projects after mid-2026¹.
  • For example, a $250,000 HVAC upgrade that qualified under § 179D could deliver $25,000–$50,000 in tax deductions, savings that disappear once the repeal takes effect.
  • Without § 179D, payback periods could stretch longer with ROI dropping by 10–20% on similar projects².


What This Means for Your Property

If you’ve been planning energy-efficient upgrades and counting on § 179D:

  • Your ROI will be lower — you’ll need to depend on state programs, utility rebates, or direct energy savings.
  • Any deals assuming § 179D must be re-checked and adjusted.
  • Getting upgrades done before June 30, 2026 can help maintain property value since future buyers won’t have this tax break.


If you’re a retail property owner looking at upgrades, whether for lighting, HVAC, windows, or insulation, this repeal changes the game. Let’s review your projects, see if they can begin in time to qualify, and adjust your cash flow plan. Call or DM me to map out your best move.


With § 179D ending on June 30, 2026, what upgrades will you push forward now and will they still hold value once the tax break is gone?

This Signal Triggered Before the Last 4 Recessions. It Just Happened Again. The question of whether the U.S. economy is heading toward recession is a polarizing one. On one hand, GDP grew at a 4.4% annualized clip in the third quarter. The unemployment rate is still in the 4% to 5% range. Inflation is still well above the Federal Reserve's target but it's also sustainably below the 3% level...

By Marc Perlof | MarcRetailGuy February 16, 2026 If you own retail real estate, here’s what just changed for you. Retail Developers: Why Your Deal Dies After You “Win” the Site Winning the site is not the win. Making the numbers work is the win. Today, many retail deals fail after the land is secured. Not because the site is bad. Because the math breaks when the market changes. If you own retail property, you must understand: Retail development underwriting. Retail real estate return on cost. Retail development exit cap rates. Retail capital stack risk. Retail tenant lease-up risk. These are no longer just developer terms. They determine whether your investment survives. Let’s look at the math. Example: You build a retail project for $12 million. You expect $1,000,000 in annual net operating income. Your retail real estate return on cost is: $1,000,000 ÷ $12,000,000 = 8.33% That looks strong. Now look at your exit. If buyers price the deal at a 6.75% cap rate, the value is: $1,000,000 ÷ 0.0675 = $14.8 million. Now stress test it. What if: Construction costs rise 8% Tenant Allowance costs rise Leasing is delayed 6 months Retail development exit cap rates expand 0.75% New total cost: $12.96 million New exit cap: 7.50% New value: $13.33 million Your profit shrinks fast. That is how deals die. Now let’s talk about retail capital stack risk. Most retail developments today use: 60 to 65% senior bank debt 10 to 15% mezzanine or preferred equity 20 to 30% sponsor equity If lease-up slows, lenders may: Increase reserves Delay refinancing Restrict distributions Tighten loan covenants Even a good property can become a weak investment. Retail tenant lease-up risk is another hidden problem. If your anchor tenant opens late: Interest continues Carry costs increase CAM recovery slows Cash flow weakens A short delay can materially impact your return. What does the market show? Retail vacancy remained near 5% in 2025, even as leasing velocity slowed.¹ Net lease cap rates averaged around the high 6% range in late 2025, with investors focused more on tenant quality and lease term than rate movements alone.² Assets with strong credit tenants and longer lease terms continue to command better pricing.² These trends mean one thing. Your retail real estate return on cost must exceed your retail development exit cap rate by a meaningful spread. A thin margin no longer protects you. If you earn 8.25% and expect to exit at 6.75%, that 1.5% gap may not be enough once capital stack risk and lease-up risk are fully modeled. Today’s retail development underwriting must include: Cap rate expansion Lease-up delays Construction overruns Higher cost of capital If your deal cannot survive realistic stress testing, it is not an investment. It is a momentum trade. If you own retail real estate or are planning a development, do not rely on optimistic pro formas. I stress test return on cost, exit assumptions, tenant structure, and capital stack exposure before capital is committed. Call or DM me for more information. What happens to your current property value if exit cap rates expand and your next tenant takes longer to open than expected? #RetailDevelopmentUnderwriting #RetailRealEstateReturnOnCost #RetailDevelopmentExitCapRates #RetailCapitalStackRisk #RetailTenantLeaseUpRisk

Taco Bell Stays Hot as Sales Continue to Rise Taco Bell remains unfazed by macroeconomic pressures.  The Mexican giant’s U.S. same-store sales lifted 7 percent in the fourth quarter—fueled by transaction growth—and it continued to grab market share. Also, system sales lifted 8 percent and core operating profit rose 10 percent. The favorable financial results are coming from a variety of sources, including higher-income customers, families, and younger guests (the brand’s highest penetration of consumers came from 18 to 24-year-olds)..
