Farm & rural
With USDA REAP grants paused in 2026, the federal money left for farm solar is the business side: the Section 48E investment credit (up to 30% for most farm-scale systems) plus accelerated depreciation. But it all hinges on a hard July 4, 2026 begin-construction clock — and the dollar value depends entirely on your tax situation.

Short answer: Yes, there is still real federal money for farm solar in 2026 — just not the grant. With USDA REAP grants paused, what's left is the business side: the Section 48E clean electricity investment credit (6% base, up to 30% — and most farm-scale systems under 1 megawatt get the full rate with no prevailing-wage paperwork), plus +10 percentage points each for domestic-content and energy-community adders, plus accelerated depreciation. The catch: it's a business credit whose value depends entirely on your tax liability, and the clock is statutory — you generally want to begin construction on or before July 4, 2026, or place the system in service by December 31, 2027. Talk to your CPA before you sign anything, then get a free farm-solar estimate.
If you've been following the REAP news, you already know the disappointing part: the grant that used to cover a big slice of a farm solar project is on hold. The natural next question is "is there anything left?" This article walks the federal stack that did survive — in plain English, with the timing front and center and a reminder that we are not your tax advisor.
Three things happened, and it's worth separating them cleanly because they get conflated constantly:
That last point is the whole ballgame. Section 48E is a business credit — it's determined with respect to a taxpayer's "qualified investment" in a qualified facility used to generate electricity, placed in service after December 31, 2024. A working farm putting panels on a barn roof or a field to power its operation is exactly the kind of taxpayer that claims it. A homeowner is not.
The mechanics are simpler than the jargon suggests.
PWA compliance is real paperwork — paying laborers prevailing wages and using registered apprentices — and it's a headache most farmers would rather skip. Here's the good news, and it's the single most important detail for farm-scale solar:
A qualified facility with a maximum net output of less than one megawatt (measured in alternating current) under sections 45Y and 48E is eligible for the increased credit amount without satisfying the prevailing-wage and apprenticeship requirements. — IRS Prevailing Wage and Apprenticeship FAQ
Most farm arrays are well under 1 MW. If yours is, you can be eligible for the full 30%-tier rate without the wage and apprenticeship compliance burden. One caveat worth stating plainly: the 1 MW threshold is measured by maximum net output in AC, so don't assume the exemption applies — have your installer and CPA confirm your system's rated output.
"Qualified investment" roughly means your basis in the eligible solar property you place in service. There are also mechanisms like elective pay (sometimes called "direct pay") and transferability that change how some taxpayers monetize the credit — but those are situation-specific and beyond this overview. Your tax advisor is the right person to tell you which applies to your farm.
On top of the 30%-eligible rate, two bonus adders can apply:
Here's how the stack builds — but read the eligibility note on every row, because none of these are automatic:
| Layer | Rate effect | What it depends on |
|---|---|---|
| Base credit | 6% | Qualified investment in the facility |
| Full (30%-tier) rate | Up to 30% | PWA compliance — or the under-1-MW exemption (max net output, AC) |
| Domestic-content adder | +10 pts | Steel/iron/manufactured-product sourcing meets the domestic-content test — verify your equipment |
| Energy-community adder | +10 pts | Your site sits in a designated energy community — verify your location |
There's no single headline percentage here, because whether the adders apply is site- and equipment-specific. They may qualify your project; they may not. Be wary of anyone who promises the adders without checking your actual panels and your actual parcel.
This is where the stack gets genuinely valuable — and genuinely the most dependent on your specific tax situation.
Business solar property has long been eligible for accelerated cost recovery. The IRS's administrative position is that owners of qualified clean energy property placed in service after December 31, 2024, may be eligible for 5-year MACRS depreciation — a 5-year recovery period under the modified accelerated cost recovery system.
But there's an unsettled wrinkle. Section 70509 of the OBBBA (P.L. 119-21) removed solar and wind energy property from the statutory definition of 5-year property for property beginning construction after December 31, 2024. That creates a genuine tension with the IRS cost-recovery page's broader "placed in service after 12/31/2024" framing. There isn't a settled answer on this point — it's exactly the kind of open question your tax professional needs to pin down for your project's facts.
On top of MACRS sits bonus depreciation, and here the news is clearer:
OBBBA §70301 provides a permanent 100 percent additional first-year (bonus) depreciation deduction for qualified property acquired after January 19, 2025. — IRS Notice 2026-11
That 100% bonus deduction applies to most tangible property with a recovery period of 20 years or less — which includes 5-year property — and the analysis found no solar-specific carve-out from bonus eligibility. (Ignore any old "40% for 2025" phase-down figures you may have seen — that was the pre-OBBBA schedule, not the current rule.)
The hard caveat: depreciation reduces your basis, it interacts with the credit's own basis-reduction rule, and it only helps if you have taxable farm income to deduct against. A deduction is worth nothing if you have no income to offset. This is the single most CPA-dependent piece of the whole stack — do not let anyone quote you a depreciation "benefit" as if it's a guaranteed check.
Everything above is real — and time-limited. This is the part to internalize, and it's statutory, so it isn't going anywhere: OBBBA §70513 terminates the §48E credit for solar facilities placed in service after December 31, 2027. And the credit termination applies to solar facilities the construction of which begins after July 4, 2026 — the date 12 months after the OBBBA's July 4, 2025 enactment. In plain terms: to stay clear of the termination, you generally want construction to begin on or before July 4, 2026, or otherwise place the system in service by December 31, 2027. Don't read the begin-construction date loosely — work that starts on July 5 is on the wrong side of the line.
So how do you prove you began construction in time? Here is where you need the current state of play, because it shifted in June 2026 and a lot of stale advice is circulating.
For most of the past year, IRS Notice 2025-42 said the Physical Work Test was the sole method to establish beginning of construction for 45Y/48E wind and solar (the long-standing 5% cost safe harbor was off the table, except for low-output solar facilities of 1.5 MW AC or less). Then, on June 6, 2026, a federal court vacated that Notice in its entirety. In Oregon Environmental Council v. IRS, the U.S. District Court for the District of Columbia held the IRS acted arbitrarily and capriciously and set the Notice aside for all taxpayers, which restores the 5% safe harbor as a method to establish beginning of construction alongside the Physical Work Test.
Read that carefully, because the takeaway is "this is unsettled," not "you have more room." The statutory July 4, 2026 deadline and the December 31, 2027 backstop both survive the ruling untouched — they come from the OBBBA, not the vacated Notice. What's in flux is only how you prove you started in time, and the government is widely expected to appeal or issue new guidance. Don't bet your project on a court fight that may not be resolved before the deadline.
What does that mean for a farmer trying to act before July 4? The conservative, defensible play is to plan as if the Physical Work Test still governs and document everything. Under the Notice's own (now-vacated, but still instructive) standard:
On-site physical work of a significant nature may include installing racks or other structures to affix PV panels, collectors, or solar cells. Preliminary activities — planning, designing, securing financing, obtaining permits, and conducting surveys do not count. — IRS Notice 2025-42
There's also a continuity safe harbor that long predates the dispute: a facility is treated as satisfying the continuity requirement if it's placed in service by the end of a calendar year no more than four calendar years after the year construction began.
This is exactly why you should be skeptical of any installer who tells you to "just sign and you're safe-harbored." Beginning construction is a real, fact-specific test — not a deposit, not a signed contract. And given the legal whiplash of June 2026, anyone selling you false certainty about your begin-construction position is someone to slow down with. If a salesperson is vague about how your project clears the deadline, that's a red flag. (We cover the full list in solar scams and red flags in 2026.)
There's no single dollar figure or payback period to quote — that depends entirely on your tax liability, your project costs, and which adders you actually qualify for. Here's the landscape:
| Program | 2026 status | Notes |
|---|---|---|
| Residential credit (25D) | Dead | Ended for systems installed after 12/31/2025 |
| Business credit (48E) | Alive — with a clock | Up to 30% (most farm systems under 1 MW skip PWA), plus possible +10/+10 adders; begin construction on or before 7/4/2026 |
| Accelerated depreciation | Alive | 5-year MACRS (one open question) + permanent 100% bonus; only helps with taxable income |
| REAP grants | Paused | No new awards/applications until updated regulations are in effect |
| REAP guaranteed loans | Open | Still available |
Conceptually, a farm that owns its array for business use might combine the 48E credit + bonus depreciation + any state or utility programs into a meaningful cut to net cost. But every figure in that sentence is "depends on your situation," and none of this is tax advice.

Yes — but it's the business credit, not the homeowner one. The residential credit (Section 25D) ended for systems installed after December 31, 2025. A farm that installs solar for its business can claim the Section 48E clean electricity investment credit, which survived: a 6% base rate that rises to up to 30%, and for most farm-scale systems (under 1 MW of maximum net output, AC) you get the full rate without prevailing-wage and apprenticeship paperwork. The credit only helps if you have tax liability, so talk to your CPA.
It can be. The base is 6%, but it rises to up to 30% if you meet prevailing-wage and apprenticeship requirements — and a qualified facility with maximum net output under 1 megawatt (AC) is exempt from those requirements while remaining eligible for the increased rate. Many farm arrays fall under 1 MW. On top of 30% you may add +10 percentage points for domestic content and +10 for an energy community, but those are site- and equipment-specific, so verify before counting on them — don't let anyone promise them sight unseen.
It's a statutory begin-construction deadline from the OBBBA: the §48E credit termination applies to solar facilities whose construction begins after July 4, 2026, so you generally want construction to begin on or before that date — or otherwise place the system in service by December 31, 2027. How you prove construction began is in flux: a June 6, 2026 federal court ruling (Oregon Environmental Council v. IRS) vacated IRS Notice 2025-42 and restored the 5% safe harbor alongside the Physical Work Test, but the matter is unsettled and may be appealed. The deadline itself is unchanged, so document your begin-construction position carefully and have your CPA confirm it.
Likely yes, but this is the most situation-dependent piece, so confirm with your CPA. Business solar property has generally been eligible for accelerated depreciation: 5-year MACRS plus 100% bonus depreciation, which OBBBA made permanent for qualified property acquired after January 19, 2025. One open wrinkle: OBBBA also changed the statutory 5-year-property definition for solar beginning construction after December 31, 2024, which your tax advisor should pin down for your project. And remember — depreciation only helps if you have taxable farm income to offset.
USDA stopped new REAP grant awards and is not accepting grant applications in 2026 (guaranteed loans are still open), so the grant is off the table for now. The remaining federal support is the 48E investment credit plus depreciation, which together can still meaningfully cut the net cost of a farm system — but the dollar value depends entirely on your tax liability and your project's timing. There's no single number to promise up front; get an estimate and run it by your accountant before signing anything.
