Important 2026: The residential 25D tax credit is DEAD (expired Dec 31, 2025). But the Section 48/48E commercial ITC is STILL available: begin construction on or before July 4, 2026 to lock in the full timing pathway; begin after and it still qualifies but generally must be placed in service by December 31, 2027. The third-party system owner (financing company) claims the ITC, NOT the installer or the business occupying the building (unless the business owns the system outright).
The Section 48/48E commercial ITC is STILL available for NJ commercial solar. Begin construction on or before July 4, 2026 to lock in the full timing pathway (placed in service through roughly 2030); begin after and it still qualifies but generally must be placed in service by December 31, 2027. The third-party system owner claims 30% base + bonus adders up to 70%. NJ also offers SuSI ADI for projects up to 5 MW ($100-110/MWh for 15 years, +$20/MWh for public entities), SuSI CSI for projects >5 MW, 1:1 net metering up to 5 MW, sales tax exemption (6.625%), 100% property tax exemption, and MACRS depreciation (100% bonus, permanent under OBBBA).
The Section 48/48E commercial ITC allows stacking multiple bonuses on top of the 30% base. The third-party system owner claims these credits -- NOT the installer.
| Component | Rate | Requirement |
|---|---|---|
| Base ITC | 30% | Begin construction before July 4, 2026 |
| Domestic Content Bonus | +10% | Meet domestic content requirements (supply chain verification) |
| Energy Community Bonus | +10% | Project located in a qualifying energy community |
| Low-Income Bonus | +10-20% | Project in low-income community or affordable housing |
| MAX STACKED | Up to 70% | Third-party system owner claims ITC |
Critical: The third-party system owner (financing company/developer) claims the ITC. If a business uses a PPA, the PPA provider claims the ITC and passes savings through lower PPA rates. Businesses DO NOT claim the ITC directly unless they own the system outright.
5-year accelerated depreciation lets businesses deduct commercial solar costs quickly. Under OBBBA, the 100% first-year bonus (permanent) maximizes tax benefits.
| Item | Amount |
|---|---|
| System Cost | $1,000,000 |
| 30% ITC | -$300,000 |
| Depreciable basis (Cost - 50% of ITC) | $850,000 |
| Year 1 Deduction (100% bonus x $850K) | $850,000 |
| Remaining depreciated in later years | $0 |
| Total tax benefit (21% rate) | $478,500 |
New Jersey levies one of the highest state corporate tax rates in the country. For a business that owns its solar system, that high rate turns MACRS depreciation into a far more valuable tax shield than it is in low-rate states: every dollar of deduction is worth more when your combined marginal rate is higher.
MACRS depreciation reduces both federal and state taxable income. The federal corporate rate is 21%. New Jersey then layers on its tiered Corporation Business Tax (CBT), which reaches roughly 9% for companies with income above $100,000 (and has reached 11.5% under NJ’s historical CBT surtax). That means the same MACRS deduction shields income at a markedly higher combined rate than it would in a no-corporate-tax or low-rate state. For a profitable New Jersey business, that state differential is real money that a generic commercial-solar page can’t capture.
| Tax Layer | Rate | What MACRS Shields |
|---|---|---|
| Federal Corporate | 21% | Applies in every state |
| New Jersey CBT | ~9-11.5% | Additional state layer on shielded income |
| Combined (approx.) | ~30-32% | Full MACRS shield value for a profitable NJ business |
General statewide rates; your exact marginal rate depends on income and entity structure. NJ state depreciation only partially conforms to federal rules — confirm NJ-level bonus depreciation treatment with your tax advisor. The illustrative 100 kW economics elsewhere on this page use a 21% federal-only rate to stay conservative.
Practical takeaway for NJ: a tax-paying business that owns its system (cash or loan) captures the 30% ITC, the CBT-amplified MACRS shield, SuSI ADI revenue, and electric-bill savings simultaneously. PPA and lease structures pass the tax benefits to the third-party system owner — the right choice for tax-exempt entities, but it leaves the CBT value on the table for a tax-paying New Jersey business.
The +10% domestic content bonus is one of the most valuable ITC adders. The July 4, 2026 date (the same window as the Section 48E begin-construction pathway) also governs how the Foreign Entity of Concern (FEOC) rules apply to domestic-content eligibility. The practical path for an NJ project: document panel and inverter origin with your installer from the start of design, because procurement lead times (4-12 weeks) mean supply-chain verification has to start well before the target date.
Do not conflate the two: beginning construction on or before July 4, 2026 locks in the full Section 48E timing pathway (placed in service through ~2030); beginning after still qualifies but generally must be placed in service by December 31, 2027. The +10% domestic content bonus is a separate supply-chain eligibility calculation.
New Jersey offers production-based solar incentives through the Successor Solar Incentive (SuSI) program. These stack on top of the federal ITC and MACRS.
SuSI is the successor to New Jersey’s former SREC market and the interim Transition (TREC) program. Each SuSI certificate represents real metered solar production and is administered by the New Jersey Board of Public Utilities (NJ BPU). Unlike a one-time tax credit, SuSI payments flow over 15 years on the energy the system actually generates — making it a contractual revenue stream, not an estimate.

Commercial solar prices in New Jersey range from $1.15/W to $2.40/W depending on system size. Larger projects have lower per-watt costs due to economies of scale.
| Tier | Size | Price $/W | Example | Example Cost |
|---|---|---|---|---|
| Small Business | 25-100 kW | $1.95-$2.40/W | 50 kW | $97,500-$120,000 |
| Mid-Size Commercial | 100-500 kW | $1.50-$1.85/W | 250 kW | $375,000-$462,500 |
| Large-Scale | 500-2,000 kW | $1.15-$1.45/W | 1,000 kW | $1,150,000-$1,450,000 |
Prices are estimates before incentives (ITC, MACRS, SuSI ADI). Actual costs vary by project complexity, equipment, and site conditions. Average NJ commercial electricity rate is $0.146/kWh.
A 100 kW commercial solar system for a typical New Jersey business with $0.146/kWh commercial rate and SuSI ADI program.
Estimates based on NJ commercial rate $0.146/kWh, 3%/yr escalation, 1,200 kWh/kW/yr production, 21% tax rate. Actual results vary.
This is one of the most misunderstood points in commercial solar. The ITC is claimed by the system OWNER, not the installer and not necessarily the business.
Who claims the ITC: The PPA provider (financing company/developer)
How the business benefits: The PPA provider passes ITC savings through lower $/kWh rates. The business pays $0 upfront and gets electricity at lower cost than the utility rate.
Best for: Nonprofits, public entities, businesses without tax appetite
Who claims the ITC: The lessor (financing company that owns the system)
How the business benefits: Fixed monthly payments lower than they would be without the ITC. Maintenance included.
Best for: Businesses wanting predictable costs without ownership complexity
Who claims the ITC: The business (as the system owner)
How the business benefits: The business directly claims the 30% ITC + bonuses on their federal tax return, PLUS MACRS depreciation. Highest long-term savings.
Best for: Profitable businesses with sufficient tax liability
The installer NEVER claims the ITC
The installer is a contractor who performs the installation work. The ITC is claimed by the entity that OWNS the solar system. If an installer tells you they claim the ITC, that is incorrect -- unless they are also the third-party system owner/financier.
Four main paths to finance commercial solar in New Jersey. Each has different implications for who claims the ITC.
| Type | Who Claims ITC | Upfront Cost | Best For |
|---|---|---|---|
| PPA (Power Purchase Agreement) | PPA Provider | $0 | Nonprofits, public entities, cash-constrained businesses |
| Solar Lease | Lessor (Finance Company) | $0 | Businesses wanting predictable costs without ownership complexity |
| Commercial Loan | Business (if they own the system) | 10-20% down | Profitable businesses with strong tax appetite |
| Cash Purchase | Business | 100% | Well-capitalized businesses seeking maximum ROI |
Critical dates to maximize commercial solar benefits in NJ.
December 31, 2025
$0 federal tax credit for homeowners who buy solar with cash or loan. Does NOT apply to commercial projects.
July 4, 2026
Begin construction on or before July 4, 2026 to lock in the full Section 48E timing pathway (placed in service through ~2030). Begin after and the project still qualifies but generally must be placed in service by December 31, 2027. Also the FEOC date for domestic content eligibility.
December 31, 2027
Projects that begin construction AFTER July 4, 2026 still qualify for the ITC but generally must be placed in service by December 31, 2027. Projects that begin on or before July 4, 2026 are not subject to this cutoff. The 100% MACRS bonus depreciation is permanent under OBBBA.
Yes. The Section 48/48E commercial Investment Tax Credit (ITC) is still available for commercial solar in 2026 through two pathways. Projects that begin construction on or before July 4, 2026 lock in the full timing pathway (placed in service through roughly 2030). Projects that begin construction after that date can still qualify but generally must be placed in service by December 31, 2027. The base rate is 30%, with bonus adders for domestic content (+10%), energy community (+10%), and low-income projects (+10-20%) that can stack up to 70%. This is different from the residential 25D credit which expired December 31, 2025. For a commercial project, the third-party system owner (developer or financing company) claims the ITC, not the business occupying the building.
The entity that OWNS the solar system claims the Section 48/48E ITC. If a business buys the system outright with cash or a loan, they claim the ITC on their federal tax return. If the project uses a PPA or lease structure, the third-party developer/financing company that owns the panels claims the ITC and passes the savings to the business through lower PPA rates or lease payments. The installer does NOT claim the ITC -- only the system owner does. Nonprofits and tax-exempt entities can benefit through PPA/lease structures where the for-profit system owner claims the credit.
The Successor Solar Incentive (SuSI) Administratively Determined Incentive (ADI) is New Jersey's production-based incentive for solar projects up to 5 MW. Non-residential projects receive approximately $100-110/MWh for 15 years, with public entities (schools, municipalities, government buildings) receiving an additional +$20/MWh bonus. This is paid on actual production, not capacity, making it a reliable revenue stream that significantly improves project economics. ADI payments stack on top of the federal ITC and MACRS depreciation.
The Modified Accelerated Cost Recovery System (MACRS) allows businesses to depreciate commercial solar systems over 5 years for tax purposes, even though the panels last 25+ years. Under OBBBA, 100% first-year bonus depreciation is permanently restored for property placed in service after January 19, 2025, so the entire depreciable basis can be deducted in Year 1. The ITC reduces the depreciable basis by half the credit claimed (e.g., with a 30% ITC, the depreciable basis is 85% of total cost). Because the 100% bonus is permanent rather than a phasedown, the timing benefit no longer disappears in 2027.
Commercial solar costs in New Jersey range from $1.15/W to $2.40/W depending on system size. Small business systems (25-100 kW) cost $1.95-$2.40/W, mid-size commercial (100-500 kW) costs $1.50-$1.85/W, and large-scale projects (500+ kW) cost $1.15-$1.45/W. A typical 100 kW small commercial rooftop system costs $195,000-$240,000 before incentives. After the 30% ITC, MACRS depreciation, and SuSI ADI revenue, the effective cost is substantially lower.
The Foreign Entity of Concern (FEOC) deadline is July 4, 2026. After this date, solar projects using components manufactured by foreign entities of concern (primarily certain Chinese companies) may lose eligibility for the domestic content bonus (+10% ITC adder). To qualify for the full domestic content bonus, projects need to verify their supply chain meets domestic content requirements. This is especially relevant for the 10% domestic content ITC bonus adder. Projects should begin supply chain verification now to ensure compliance before the deadline.
Yes, though indirectly. Nonprofits, schools, municipalities, and other tax-exempt entities cannot claim the ITC directly since they have no federal tax liability. Instead, they use PPA or lease structures where a for-profit third-party developer owns the system and claims the ITC. The savings are passed to the nonprofit through lower PPA rates. Additionally, the Inflation Reduction Act introduced "direct pay" (elective payment) for certain tax-exempt entities, allowing them to receive the ITC as a direct payment. NJ public entities also receive the +$20/MWh SuSI ADI bonus.
The Competitive Solar Incentive (CSI) is the SuSI program tier for large solar projects exceeding 5 MW. Unlike the ADI which has a fixed rate, CSI uses a competitive auction process where developers bid for incentive levels. This typically results in lower $/MWh rates than ADI but is designed for utility-scale and large commercial/industrial projects. CSI projects are awarded through periodic solicitation rounds conducted by the NJ Board of Public Utilities. The 15-year incentive term applies to CSI as well.
New Jersey offers net metering for commercial solar systems up to 5 MW. Excess electricity exported to the grid receives a 1:1 credit at the retail rate on your utility bill. Credits roll over monthly and are trued up annually. This means a commercial system that generates more than the business uses during sunny periods banks credits for use during evenings and high-demand periods. NJ net metering applies to all major utilities (PSE&G, JCP&L, ACE). Combined with SuSI ADI revenue, net metering significantly improves commercial solar economics.
New Jersey offers two significant tax exemptions for solar: (1) Sales tax exemption -- solar equipment is exempt from the 6.625% NJ sales tax, saving thousands on a commercial installation, and (2) Property tax exemption -- solar systems are 100% exempt from property tax increases. This means a $500,000 commercial solar system adds $0 to your property tax bill. In New Jersey, where property taxes average $9,500/year, this exemption is extremely valuable. These exemptions apply to both residential and commercial solar installations.
A typical NJ commercial solar project takes 6-12 months from initial assessment to operation. The timeline includes: site assessment and engineering (2-4 weeks), financing/contracting (4-8 weeks), permitting and utility interconnection application (4-8 weeks), equipment procurement (4-12 weeks depending on availability), installation (2-6 weeks depending on size), inspection and interconnection (2-4 weeks), and SuSI ADI registration. To lock in the full Section 48E timing pathway, projects should begin construction on or before July 4, 2026 (this is also the FEOC date for domestic-content eligibility); 100% MACRS bonus depreciation applies regardless of timing under OBBBA.
When combining MACRS with the ITC, the depreciable basis is reduced by half the ITC amount. For example, with a $1,000,000 system and 30% ITC ($300,000 credit), the depreciable basis is $1,000,000 - ($300,000 x 50%) = $850,000. Under OBBBA, 100% first-year bonus depreciation means the full $850,000 basis can be deducted in Year 1, leaving $0 to depreciate over the remaining MACRS schedule. Because the 100% bonus is permanent (not a phasedown that expires in 2027), the depreciation benefit is the same whether a project is placed in service this year or later.
Begin construction on or before July 4, 2026 to lock in the full Section 48E timing pathway; begin after and the project still qualifies but generally must be placed in service by December 31, 2027. Do not wait.
