Only 7 months left to claim up to $5,000 per home!
If you're a home builder, renovator, or producer of manufactured homes, consider this your friendly December nudge. The clock is ticking on one of the most valuable federal incentives available to your industry.
📋 Quick Navigation
The Energy Efficient Home Builder Credit (IRC §45L) can deliver up to $5,000 per qualifying home. But thanks to the One Big Beautiful Bill Act, this credit disappears for homes acquired after June 30, 2026. And "acquired" means bought or leased by a residential buyer or tenant. Translation: the window is closing fast.
Think of this as a government-sponsored holiday countdown. Minus the cookies, but with meaningful tax savings that could transform your bottom line.
With construction costs rising, profit margins tightening, and competition fiercer than ever, the energy efficient home builder credit represents one of the last significant tax incentives available to residential builders. But it requires planning, proper documentation, and most importantly, meeting the hard June 30, 2026 deadline.
Understanding the Energy Efficient Home Builder Credit
The §45L credit was created to incentivize builders to construct homes that meet rigorous energy efficiency standards. Congress periodically extends this credit, but the current extension ends definitively on June 30, 2026.
This isn't a "maybe we'll extend it" situation. The One Big Beautiful Bill Act explicitly terminates the credit for homes acquired after that date. No extensions are anticipated, which makes this truly a use it or lose it opportunity.
For context, a builder completing 20 single-family homes that qualify for the maximum $5,000 credit walks away with $100,000 in tax savings. A multifamily developer building a 50-unit apartment complex with proper prevailing wage compliance could capture $250,000. These aren't trivial amounts. They're transformative for your business's tax position.
The energy efficient home builder credit has been one of the most underutilized tax incentives in the construction industry, primarily because builders either don't know about it or assume the certification requirements are too burdensome. In reality, with modern construction techniques and the increasing affordability of energy-efficient materials, most quality builders are already close to meeting the standards.
Who Qualifies for the Credit?
To claim the §45L credit, three fundamental requirements must be met:
You Built or Substantially Reconstructed a Qualified Energy Efficient Home
Single-family homes, multifamily units, and manufactured homes may all qualify. "Substantial reconstruction" means you did more than just routine maintenance. You fundamentally rebuilt the dwelling to meet energy efficiency standards.
The home must be certified under Energy Star or Zero Energy Ready Home (ZERH) programs. This certification is mandatory. You can't claim the credit without it.
Good News for Most Builders: Energy Star certification isn't as difficult or expensive as it sounds. Most homes built to modern code are already 60 to 80 percent of the way there. The incremental cost to achieve certification often ranges from $1,000 to $3,000 per home, which is immediately recovered through the $2,500 to $5,000 tax credit.
You Owned the Home During Construction
Even if you hire a third-party contractor to handle the actual building, you (the entity with basis in the property) earn the credit. This is important for builders who use subcontractors extensively. As long as you maintain ownership throughout the construction process, the credit belongs to you.
For developers who structure deals with joint ventures or complex ownership arrangements, determining who can claim the energy efficient home builder credit requires careful analysis. Generally, the party with the economic interest in the property during construction (the one at risk if the project fails) is the party entitled to the credit.
A Buyer or Residential Tenant Must Acquire the Home by June 30, 2026
Here's where timing becomes critical. "Acquire" means purchase or lease for use as a residence. Your company cannot retain the property and claim the credit. An individual must take possession for residential use before July 2026 arrives.
For manufactured home producers, the purchase may occur through an intermediary (such as a dealer), but the ultimate end user must be an individual using it as a residence.
CRITICAL TIMING NOTE: The June 30, 2026 deadline is absolute. There's no "postmark by" provision, no grace period, no flexibility. If the closing doesn't happen by June 30, the credit is lost forever for that home.
What Counts as an Energy Efficient Home?
A qualifying home must satisfy three conditions:
Location: The home must be located in the United States.
Use: It must be purchased or leased by an individual for residential use (not commercial or investment property, though investors who rent to residential tenants may qualify).
Certification: It must meet applicable Energy Star requirements or Zero Energy Ready Home standards as defined by the Department of Energy.
If your homes already participate in energy-efficient programs, you're ahead of the game. If not, the certifications are straightforward, but they must be completed before you can claim the credit, and you must retain documentation proving certification.
Many builders mistakenly believe energy efficiency standards are prohibitively expensive to meet. In reality, modern construction techniques and materials have made energy-efficient building increasingly cost-effective. The incremental cost of meeting Energy Star standards is often recovered through the tax credit alone, before considering the marketing advantage of offering energy-efficient homes to environmentally conscious buyers.
How Much Is the Energy Efficient Home Builder Credit Worth?
Depending on energy standards and labor requirements, credits range from $500 to $5,000 per unit. Here's the breakdown:
Single-Family Homes & Manufactured Homes
If certified under an Energy Star program, you receive $2,500. If also certified as a Zero Energy Ready Home (ZERH), the credit doubles to $5,000.
For single-family builders, the calculation is straightforward. If you're building quality homes with modern insulation, efficient HVAC, and good windows, achieving Energy Star certification should be relatively easy. If you're building premium homes with high-end energy features, pursuing ZERH certification for the doubled credit makes financial sense.
Multifamily Units
- $500 per unit for Energy Star certification
- $2,500 per unit if Energy Star plus prevailing wage requirements met
- $1,000 per unit for ZERH certification
- $5,000 per unit for ZERH plus prevailing wage requirements met
Understanding Prevailing Wage Requirements
Prevailing wage rules matter significantly for multifamily developers. If you want the enhanced credit (which can be 5x larger), your laborers, contractors, and subcontractors must be paid at least the local prevailing wage for comparable work as determined by the Department of Labor.
This isn't always difficult to achieve. Many builders already meet these standards. But you must document compliance carefully, as the IRS takes prevailing wage requirements seriously.
Prevailing wage determinations are published by the Department of Labor and vary by location and trade. For example, the prevailing wage for electricians in Houston differs from that in rural East Texas. Builders must track wages paid to all workers on the project and maintain documentation proving compliance.
WARNING: Homes must be acquired by residential buyers or tenants by June 30, 2026. After this date, the energy efficient home builder credit disappears entirely. No extensions, no exceptions, no second chances. Plan your construction and closing schedules accordingly.
Why This Credit Matters More Than Ever
Let's talk about the financial reality of homebuilding in 2025 and 2026.
Construction costs have increased dramatically over the past few years. Lumber prices, while somewhat stabilized, remain elevated compared to pre-pandemic levels. Labor costs continue rising as skilled trades become harder to find. Supply chain issues, though improved, still create delays and uncertainty. In this environment, every dollar of margin matters.
A $5,000 tax credit per home represents 2 to 5 percent of the typical single-family home's profit margin. For a builder completing 50 homes annually, that's $250,000 in tax savings. Enough to fund expansion, weather market downturns, or simply improve profitability in a challenging market.
But beyond the financial benefits, the energy efficient home builder credit creates a competitive advantage. Today's homebuyers increasingly prioritize energy efficiency. They understand that an energy-efficient home means:
- Lower utility bills (often 20 to 30 percent savings monthly)
- Greater comfort with consistent temperatures
- Better indoor air quality
- Higher resale value
- Environmental responsibility
Builders who can market their homes as Energy Star or ZERH certified command premium prices and sell faster. In competitive markets, energy certification can be the differentiator that closes the sale.
The credit essentially subsidizes you to build homes that buyers already want. That's a rare win-win in the tax code.
POTENTIAL SAVINGS CALCULATOR:
- 10 single-family homes (ZERH certified) = $50,000 in tax credits
- 50-unit multifamily complex (ZERH plus prevailing wage) = $250,000 in tax credits
- 100 manufactured homes (Energy Star) = $250,000 in tax credits
- Mixed development (20 SF plus 30 MF units) = $250,000 total
These aren't hypothetical numbers. These are real tax savings that go directly to your bottom line.
Our team at IRSProb.com has helped dozens of Texas builders capture this credit, and we've seen firsthand how it impacts businesses. The builders who plan strategically and document properly walk away with substantial tax savings. The ones who wait until the last minute often miss out entirely.
Documentation You Must Keep
While certifications don't get filed with your tax return, the IRS expects you to maintain proof of several things.
Required Documentation Checklist:
- The home's complete address including lot number and legal description
- Your status as the builder or producer with basis in the property
- Evidence the home was acquired by an individual for residential use before June 30, 2026
- The name and information of the acquiring individual
- Proof you met prevailing wage requirements (if claiming enhanced multifamily credits)
- Energy Star or ZERH certifications for each qualifying dwelling unit
These records must be retained for as long as they may be relevant for tax purposes. Typically at least three years after the return is filed, but potentially longer if the IRS audits or challenges the credit. Given the size of these credits, the IRS scrutinizes §45L claims carefully.
Many builders underestimate documentation requirements until they face an IRS audit. Don't be that builder. Create a systematic process for capturing and storing all required documentation as you complete each qualifying home.
Best Practices for Documentation:
- Create a checklist for each home
- Maintain digital and physical copies of all certifications
- Store documents in an organized file system by property address
- Back up electronic files in multiple locations
- Assign one person responsibility for documentation compliance
- Review files quarterly to ensure nothing is missing
The builders who succeed with the energy efficient home builder credit treat documentation as seriously as they treat construction quality. Both are essential to capturing the full value of the credit.
How to Claim the Energy Efficient Home Builder Credit
Builders and manufacturers file Form 8908 (Energy Efficient Home Credit) with their federal income tax return. The form is straightforward but requires specific information about each qualifying home.
If you operate as a partnership, LLC taxed as a partnership, or S corporation, the credit passes through to owners via Schedule K-1. Individual owners then report the credit on Form 3800 (General Business Credit).
Important Technical Note: Claiming the credit reduces your basis in the home by the amount of the credit claimed. This is still an overwhelmingly favorable trade-off. You're converting basis into an immediate tax credit. But the basis adjustment matters for future tax calculations and depreciation deductions.
For example, if you build a home with a total basis of $200,000 and claim a $5,000 credit, your adjusted basis becomes $195,000. If you later sell that home or convert it to a rental property, your depreciation calculations and gain or loss calculations are based on the reduced basis.
If you're unfamiliar with business tax credits or Form 8908, working with experienced tax professionals can ensure you're claiming the maximum credit available while maintaining full compliance with IRS requirements.
Common Mistakes That Cost Builders This Credit
After helping numerous builders navigate this credit, we've identified the mistakes that most commonly cause builders to lose out on savings they've earned:
Missing the June 30, 2026 Deadline
This is the big one. Homes that close on July 1, 2026 or later don't qualify, regardless of when construction started or how much money you invested. Many builders assume they can claim the credit as long as they started building before the deadline, but that's incorrect. The acquisition date by the residential buyer or tenant controls everything.
Real Example: We've seen builders with homes 95 percent complete on June 30 that closed on July 5 lose $5,000 credits because of a one-week delay. Don't let this happen to you.
Not Maintaining Proper Documentation
The IRS doesn't require you to submit certifications with your return, which lulls some builders into complacency. Then an audit arrives two years later, and they can't produce the required Energy Star or ZERH certifications. Without documentation, the credit gets disallowed, plus penalties and interest on the tax that should have been paid.
The penalty for claiming credits without substantiation can be 20 to 40 percent of the disallowed amount, plus interest calculated from the original return due date. On a $50,000 credit claimed across 10 homes, that's $10,000 to $20,000 in penalties alone.
Skipping Energy Star or ZERH Certification
Some builders construct homes that meet or exceed energy efficiency standards but never obtain formal certification. Unfortunately, the tax code requires actual certification through approved programs. Building an efficient home isn't enough. You must document it through the proper channels.
This is particularly frustrating because the home may genuinely be energy efficient, but without the official certification paperwork, the IRS won't allow the credit. The certification process costs a few hundred dollars per home and takes a few weeks. Don't skip this step.
Misunderstanding "Acquisition" Rules
Builders sometimes retain completed homes as rental properties and attempt to claim the credit. This doesn't work under the current rules. The home must be acquired by an individual buyer or residential tenant. Your company can't be the end user.
However, if you sell to an investor who immediately leases the home to a residential tenant before June 30, 2026, you can claim the credit. The key is that an individual must acquire the home for use as a residence, either through purchase or lease.
Forgetting the Basis Adjustment
Claiming the credit reduces your basis in the property. If you don't account for this correctly in your records, you'll have problems when you eventually sell the property or calculate depreciation for rental properties. This is a technical issue but one that causes headaches down the road.
Most accounting software can handle the basis adjustment automatically if you input it correctly. But if you're tracking basis manually or using basic bookkeeping systems, the adjustment is easy to overlook.
Failing to Track Prevailing Wage Compliance for Multifamily Projects
Multifamily developers pursuing the enhanced credit must document prevailing wage compliance throughout construction. Spotty records or missing documentation can disqualify you from the higher credit amount, costing thousands per unit.
The prevailing wage requirements are complex, and many builders underestimate the documentation burden. If you discover wage compliance issues after the project is complete, it may be too late to correct them and claim the enhanced credit.
Working with experienced tax professionals helps you avoid these pitfalls. We've seen all these mistakes, and we know how to prevent them.
Your Action Plan: What to Do Right Now
Seven months might sound like plenty of time, but in construction terms, it's remarkably short. Here's your strategic timeline:
Inventory all projects currently under construction. Identify which homes could qualify for the credit. Begin Energy Star or ZERH certification processes for qualifying homes. Review prevailing wage compliance for multifamily projects. Contact tax professionals for project qualification review. Create a master spreadsheet tracking all potential credit-eligible homes.
Prioritize completion of homes closest to being finished. Coordinate with contractors to accelerate timelines where possible. Ensure all subcontractors understand the importance of the June 30 deadline. Begin compiling required documentation for each qualifying home. Order energy certifications for homes nearing substantial completion.
Establish systematic processes for capturing all required documentation. Create files for each qualifying home with all necessary proof. Obtain Energy Star or ZERH certifications for homes nearing completion. If pursuing enhanced multifamily credits, compile prevailing wage documentation.
Focus resources on homes that can realistically close by June 30. Communicate deadline urgency to buyers and real estate agents. Consider incentives to accelerate closings before the deadline. Schedule closing dates strategically to ensure June 30 compliance.
Aggressive pursuit of completing remaining qualifying homes. Daily monitoring of construction timelines. Address any delays immediately, no excuses, no waiting. Ensure buyers are ready to close on schedule. Lock in closing dates with title companies and lenders.
All hands on deck to complete qualifying homes. Coordinate closely with title companies and lenders. Confirm closing dates are locked in before June 30. Complete final certifications for any remaining homes. Triple-check that all documentation is complete. Be prepared for rushed closings if necessary.
Don't Wait Until Spring 2026: This timeline might seem aggressive, but builders who wait until spring 2026 to start planning will find themselves scrambling and potentially missing out on substantial credits for homes they've already invested in building.
The builders who capture the maximum energy efficient home builder credit are the ones who treat this deadline as seriously as they treat construction schedules and budgets. It requires planning, discipline, and execution.
What Happens After June 30, 2026?
Let's be clear: this credit ends. Period.
Unlike some tax provisions that get extended at the last minute, the One Big Beautiful Bill Act explicitly terminates the energy efficient home builder credit for homes acquired after June 30, 2026. Congress could theoretically pass new legislation creating a replacement credit, but there's no indication that will happen, and there's certainly no guarantee.
For homes that close on July 1, 2026 or later, builders will need to look at alternative incentives:
- Standard business deductions for construction costs (these still apply, but they don't provide the immediate tax benefit of a credit)
- Potential state-level energy efficiency incentives (varies by state; Texas doesn't currently offer significant state-level equivalents)
- Marketing value of energy-efficient construction (buyers still want efficient homes, but you won't get the federal tax credit)
- Other business tax credits unrelated to home construction
The Bottom Line: If you have projects underway now, this is your last opportunity to capture the §45L credit. Don't assume extensions will happen. Plan as if June 30, 2026 is a hard deadline, because it is.
While anything is possible in Washington, prudent business planning requires assuming the deadline is final.

Real Example: How One Texas Builder Captured $180,000 in Credits
Let me share a real example (with details changed to protect client confidentiality) that illustrates the value of strategic planning around the energy efficient home builder credit.
The Situation: A Texas custom home builder came to us in early 2024 with 36 homes under construction across three subdivisions in the Austin area. They'd heard about the §45L credit but weren't sure if they qualified or how to claim it.
We reviewed all 36 homes under construction and determined that 32 could qualify for either the $2,500 or $5,000 credit, depending on certification level. Four homes were too far along in construction to cost-effectively achieve Energy Star certification.
We evaluated the construction specifications and energy features of each home:
- Twenty homes could achieve ZERH certification with minor modifications ($5,000 credit each)
- Twelve homes would qualify for Energy Star but not ZERH ($2,500 credit each)
- The modifications needed for ZERH certification cost approximately $2,000 to $3,000 per home but generated an additional $2,500 in tax credits
We helped them establish documentation processes, schedule construction and closings strategically, and ultimately prepared Form 8908 claiming:
But the story doesn't end there. Based on the success of this first round, the builder adjusted their construction practices for all future homes and ultimately captured an additional $50,000 in credits for 10 more homes completed in 2025.
That $180,000 in tax credits represented 3 to 4 percent of total gross revenue on those projects, increased net profit margin by 15 to 20 percent, provided cash flow to fund expansion into a new subdivision, and created a competitive marketing advantage.
This is the kind of strategic planning that separates successful construction businesses from those that leave money on the table.
