Stack the 30% base + 10% domestic content + 10% energy community + 10-20% low-income for up to 70%. MACRS 20% bonus depreciation in 2026. Texas commercial rates $0.06-$0.12/kWh. Massive warehouse and industrial roofs.
DEADLINE: July 4, 2026 — Begin Construction
Projects must begin construction before July 4, 2026 to qualify for the commercial ITC. After this date, the credit phases down or expires depending on congressional action. MACRS bonus depreciation drops from 20% to 0% in 2027.
Commercial ITC Active: Section 48/48E provides a 30% base ITC for commercial and third-party solar projects beginning construction before July 4, 2026. The residential 25D credit expired December 31, 2025 ($0 for homeowner cash/loan purchases), but the commercial credit remains available.
Costs vary by system size. Larger systems achieve significantly lower per-watt pricing due to economies of scale. Texas has among the lowest commercial solar costs in the country.
Depreciable basis = system cost - (50% of ITC) = $650,000 - $97,500 = $552,500. Year 1 MACRS at 40% (20% regular + 20% bonus) = $76,050 in tax deductions (value depends on tax bracket). Actual tax savings require consultation with a CPA.
The Section 48/48E ITC starts at 30% and can be increased through qualifying adders. Each adder has specific eligibility requirements. The maximum theoretical stack is approximately 70%.
| ITC Component | Rate | Requirement | |
|---|---|---|---|
| Base ITCRequired | 30% | Meet prevailing wage + apprenticeship requirements (projects >1 MW) | |
| Domestic Content Bonus | +10% | 100% of steel/iron manufactured in US + 40% of manufactured product costs from US sources (2026 threshold) | |
| Energy Community Bonus | +10% | Project located in a brownfield site, retired coal plant area, or statistical area with >0.17% fossil fuel employment AND above-average unemployment | |
| Low-Income Bonus (Category 1) | +10% | Located in a low-income census tract OR on Indian land. Competitive DOE allocation. | |
| Low-Income Bonus (Category 2) | +20% | Part of a qualified low-income residential building project OR low-income economic benefit project | |
| Maximum Total | Up to 70% | Qualifying for all adders simultaneously is rare. Most TX businesses realistically achieve 30-50%. | |
ITC rates and requirements per Inflation Reduction Act as modified by OBBBA (signed July 4, 2025). Projects must begin construction before July 4, 2026. Prevailing wage and apprenticeship requirements apply to projects over 1 MW. Consult a qualified tax professional for specific project eligibility.
The Modified Accelerated Cost Recovery System (MACRS) allows Texas businesses to depreciate solar equipment over 5 years instead of the system’s 25-30 year useful life. This front-loads tax deductions and dramatically accelerates payback.
Solar energy equipment is classified as 5-year property under IRS MACRS (Asset Class 00.12 — Solar Electric Generating Equipment). Instead of spreading deductions evenly over 25+ years (straight-line), MACRS uses a declining-balance method that concentrates deductions in the early years. The standard 5-year MACRS schedule (200% declining balance, half-year convention) recovers 20% in Year 1, 32% in Year 2, 19.2% in Year 3, then tapers off.
System cost minus 50% of the ITC claimed. If your ITC is 30% ($54,000 on a $180,000 system), the depreciable basis = $180,000 - $27,000 = $153,000.
The depreciable basis is recovered over 6 tax years using the percentages below. In 2026, 20% bonus depreciation is added to Year 1, giving you 40% in Year 1.
Depreciation is a deduction, not a credit. Actual tax savings = deduction × your marginal tax rate. At 21% federal (C-Corp): $153,000 × 40% × 21% = $12,852 in Year 1 alone.
| Year | Regular MACRS | 2026 Bonus | 2026 Total | 2027 Total |
|---|---|---|---|---|
| Year 1 | 20.00% | 20.00% | 40.00% | 20.00% |
| Year 2 | 32.00% | 0.00% | 32.00% | 32.00% |
| Year 3 | 19.20% | 0.00% | 19.20% | 19.20% |
| Year 4 | 11.52% | 0.00% | 11.52% | 11.52% |
| Year 5 | 11.52% | 0.00% | 11.52% | 11.52% |
| Year 6 | 5.76% | 0.00% | 5.76% | 5.76% |
| Total | 100% | 20% | 120%* | 100% |
*The 120% total is correct: 100% of the depreciable basis is recovered via standard MACRS, plus 20% bonus depreciation accelerates a portion into Year 1. The bonus does not create additional deductions — it shifts the Year 2+ amounts forward. The IRS applies bonus depreciation first, then the remaining basis follows the standard MACRS percentages.
Projects placed in service in 2026 receive 20% bonus depreciation on top of the regular 20% first-year MACRS rate. This means 40% of the depreciable basis can be written off in Year 1. For a $180,000 system with a 30% ITC, Year 1 depreciation deduction is approximately $61,200(depreciable basis $153,000 × 40%). At a 21% C-Corp rate, that saves $12,852 in federal taxes in Year 1.
Starting in 2027, the bonus depreciation rate drops to 0%. Only the regular 20% first-year MACRS rate applies. On the same $180,000 system, Year 1 depreciation falls from $61,200 to $30,600 — cutting Year 1 tax savings nearly in half. Businesses with significant tax liability should accelerate projects into 2026 to capture the extra $30,600 in first-year deductions.
The ITC is a dollar-for-dollar tax credit (directly reduces taxes owed). MACRS is a tax deduction(reduces taxable income, saving taxes at your marginal rate). Together, they stack to recover a substantial portion of the system cost in Year 1.
Example assumes 100 kW system at $1.80/W, 30% ITC only (no adders), 21% federal C-Corp rate. Depreciable basis = $180,000 - 50% of $54,000 = $153,000. Year 1 MACRS: 40% of $153,000 = $61,200 deduction, saving $12,852 at 21%. Pass-through entities (S-Corps, LLCs) may use the owner’s individual marginal rate (up to 37%).
Section 48E is the technology-neutral clean energy ITC created by the Inflation Reduction Act. For commercial solar projects placed in service after December 31, 2024, Section 48E provides the same benefits as the legacy Section 48 with an identical adder structure.
Low-income adders (+10% or +20%) are competitively allocated by DOE and difficult to obtain. Most TX businesses should plan for 30-50%.
The ITC is claimed by the entity that owns the solar system — not the installer, not the customer (unless they own it outright).
To qualify for the Section 48E ITC, a project must “begin construction” before July 4, 2026. The IRS recognizes two tests (either one satisfies the requirement):
Begin significant physical work of a nature that is integral to the project (e.g., pouring footings, installing racking). Preliminary activities (permits, site surveys) do not count.
Incur at least 5% of the total project cost before July 4, 2026. For a $180,000 system, that means spending at least $9,000 (e.g., equipment deposits, engineering fees). Then complete the project within 4 years.
The FEOC (Foreign Entity of Concern) compliance deadline is the same date: July 4, 2026. After this date, equipment containing components from FEOC-designated entities may not qualify for the domestic content bonus (+10% ITC). For TX businesses targeting the 40% ITC (base + domestic content), this means locking in FEOC-compliant equipment — such as First Solar, Silfab, Qcells, or Heliene panels — before the deadline. The domestic content bonus alone on a 100 kW system is worth $18,000.
A real-world calculation showing the total tax benefits for a 100 kW system on a Texas warehouse roof, installed in 2026 with domestic content-eligible equipment. This is a mid-size commercial system typical of strip malls, small warehouses, and office buildings across the DFW Metroplex and Houston.
| Tax Benefit | 30% ITC Only | 40% ITC (+ Domestic) | 50% ITC (+ EC) |
|---|---|---|---|
| ITC (Tax Credit) | $54,000 | $72,000 | $90,000 |
| Depreciable Basis | $153,000 | $144,000 | $135,000 |
| Total MACRS Tax Savings (21%) | $32,130 | $30,240 | $28,350 |
| 6-Year Energy Savings | $83,700 | $83,700 | $83,700 |
| Total 6-Year Value | $169,830 | $185,940 | $202,050 |
| Net Cost After 6 Years | $10,170 | $-5,940 | $-22,050 |
All figures assume 21% federal C-Corp rate. S-Corp/LLC pass-through entities at higher individual rates (24-37%) would see proportionally larger MACRS savings. Energy savings assume $0.09/kWh avg commercial rate with no annual escalation. Actual results depend on tax situation, production, and rate changes. Consult a qualified CPA.
This timeline shows the cumulative cash position for a 100 kW system with 40% ITC (base + domestic content). The system reaches breakeven within 3-4 years when combining ITC, MACRS, and energy savings.
| Period | Capital Outlay | ITC Credit | MACRS Savings | Energy Savings | Cumulative |
|---|---|---|---|---|---|
| Installation | -$180,000 | — | — | — | -$180,000 |
| Year 1 | — | +$72,000 | +$12,096 | +$13,950 | -$81,954 |

| Year 6 | — | — | +$1,742 | +$13,950 | $11,989 |
40% ITC scenario = 30% base + 10% domestic content. MACRS savings at 21% C-Corp federal rate with 20% bonus depreciation (2026). Energy savings at $0.09/kWh × 155,000 kWh/year. No financing costs assumed (cash purchase). Payback accelerates significantly for pass-through entities at higher marginal rates (24-37%).
Texas has no state income tax — but the franchise (margin) tax affects businesses with revenue above $2.47 million. Understanding how solar interacts with the franchise tax is important for accurate ROI projections.
A TX warehouse business with $5M revenue using the COGS method currently pays $200,000/year in electricity. After installing 200 kW solar, electricity costs drop to $80,000/year — a $120,000 annual reduction in COGS.
The trade-off is negligible: saving $120,000 in energy but paying ~$450 more in franchise tax. The net benefit is overwhelmingly positive. Different margin calculation methods may produce different results — consult a TX CPA.
C-PACE (Commercial Property Assessed Clean Energy) is an increasingly popular financing mechanism for commercial solar in Texas. The debt is secured by the property, not the borrower, with repayment through the property tax bill.
C-PACE can cover the entire project cost including soft costs. No upfront capital required from the property owner. Combined with ITC and MACRS, effective out-of-pocket cost can be near zero.
Long repayment terms keep annual payments low. Solar energy savings typically exceed annual C-PACE payments from Day 1, making the investment cash-flow positive immediately.
If the building is sold, the C-PACE obligation transfers to the new owner. This makes C-PACE ideal for property owners who may sell within the loan term. No personal guarantee required.
Additionally, Travis, Harris, Dallas, and Bexar counties have C-PACE programs covering unincorporated areas. Contact NuWatt Energy to verify C-PACE availability for your specific property location and get connected with approved C-PACE providers.
Commercial electricity rates in Texas are among the lowest in the nation. While low rates mean longer solar payback without incentives, the 30% ITC and MACRS dramatically accelerate ROI.

Commercial electricity bills in Texas typically include both energy charges ($/kWh) and demand charges ($/kW based on peak 15-minute usage). Demand charges can represent 30-50% of a commercial bill. Solar alone reduces energy charges but may not significantly reduce demand charges unless paired with battery storage. For maximum ROI, consider solar + battery to shave peak demand and capture both savings.
Texas has massive commercial solar potential across every industry. Large flat roofs, abundant sun, and low installation costs create ideal conditions for businesses to go solar before the ITC deadline.
Large flat roofs are ideal for solar. TX has massive logistics corridors (I-35, I-10, I-45). Amazon, FedEx, and UPS facilities across TX are going solar. Warehouse roofs generate the highest kWh per dollar due to minimal shading and optimal tilt.
Industrial facilities with high daytime electricity demand see the fastest payback. TX manufacturing boom (semiconductor fabs, petrochemical, food processing) drives commercial solar adoption. Ground-mount systems available for facilities with land.
TX farms and ranches have abundant land and high irrigation electricity costs. Ground-mount solar offsets irrigation pumping, cold storage, and processing facility loads. USDA REAP grants (up to 50% of project cost) available for agricultural solar.
Strip malls, grocery stores, and office buildings benefit from solar during peak business hours. On-site solar reduces demand charges, which can be 30-50% of a commercial electricity bill in TX. Carport solar provides shade parking as an added benefit.
The Foreign Entity of Concern (FEOC) rules impact which solar equipment qualifies for the domestic content bonus. Understanding these requirements is critical for maximizing your ITC.
After July 4, 2026, solar equipment containing components from Foreign Entities of Concern (primarily Chinese-manufactured cells and modules) will face additional restrictions. The domestic content bonus (+10% ITC) requires US-sourced materials.
Several panel manufacturers now produce modules in the US or with US-sourced cells to qualify for the domestic content bonus.
