The §30C Charging Credit
"Install a charger in the right census tract and the IRS pays for nearly a third of it — up to $100,000 per charger for businesses. The 'right tract' clause is what most people miss."
The 60-second pitch
The Alternative Fuel Vehicle Refueling Property Credit (§30C) is the IRS's check on the EV charger sitting in your garage, your business parking lot, or your apartment complex. 30% of installed cost, capped at $1,000 per charger for individuals (residential) and $100,000 per charging item for businesses (per individual depreciable property unit, not per project).
The IRA materially changed §30C in two ways. One: the credit is now per item rather than per location — a business installing 12 chargers can claim up to 12 × $100K = $1.2M of credit (subject to prevailing wage/apprenticeship for the full 30%). Two: the property has to be installed in an eligible census tract — a low-income community (under §45D(e)) or a non-urban census tract (under §147(b)(4)). Wealthy suburbs no longer qualify. Use the DOE/Treasury eligibility mapper before you install.
The OBBBA reality. The One Big Beautiful Bill Act (signed July 4, 2025) terminates §30C for property placed in service after June 30, 2026. There is no begin-construction safe harbor — only placed-in-service counts. Equipment installed and energized by June 30, 2026 qualifies; one day later, it does not.
Real-world example
The setup. Greenline runs a fleet of 18 Ford E-Transit vans out of a depot in Allentown. In Q4 2025 they invest in dedicated charging — twelve 80 kW Level 2 dual-port chargers (24 ports total) plus a transformer upgrade, conduit, concrete pads, and bollards.
Eligibility check. The depot's census tract is 42077003901. Treasury's §30C mapper shows it's a low-income community under §45D(e) (poverty rate > 20%). ✓ Eligible.
Cost breakdown. Chargers: $324,000 (12 × $27K avg installed). Transformer + utility service upgrade: $86,000. Trenching + conduit + concrete: $52,000. Bollards + signage + commissioning: $18,000. Total: $480,000.
The credit. Each "item" of property (each charger + its allocable installation costs) is its own §30C basis. Allocating evenly: $40,000 per charger. 30% × $40,000 = $12,000 per charger. 12 chargers × $12,000 = $144,000 federal credit. Greenline pays prevailing wage and apprenticeship on the install, hitting the full 30% rate (without PWA, the base rate would be only 6%).
The placed-in-service window. Project commissioned and energized December 18, 2025 — comfortably ahead of the June 30, 2026 OBBBA cliff.
The step-by-step checklist
- Map the census tract first. Use the Argonne National Lab / Treasury §30C Eligibility Locator. Address → tract ID → eligibility flag. If the tract isn't eligible, the project gets $0 of §30C — full stop.
- Confirm equipment qualifies. Level 2 AC and DC fast charging both qualify. So does hydrogen, natural gas, and propane refueling. Standard NEMA 14-50 outlets do not on their own — must be dedicated EV charging equipment.
- Plan installation by June 30, 2026. Placed in service = energized, commissioned, and ready for use. Contracts and equipment ordered but not installed don't count.
- Decide commercial vs. residential. Same code section, different caps: $1,000 cap per item residential (individuals); $100,000 cap per item commercial (business).
- Comply with prevailing wage + apprenticeship (PWA) for the 30% rate. Without PWA, the commercial rate is only 6% — a 5x difference. PWA means paying Davis-Bacon wages and ensuring 12.5–15% of labor hours are performed by registered apprentices.
- Treat each charger as a separate "item" for the cap. A 12-charger install is 12 caps of $100K, not one $100K cap. Allocate shared costs (transformer, trenching) pro rata.
- Reduce depreciable basis by the credit (§50(c)(3)). $144K credit on $480K project → depreciable basis is $336K.
- Stack with 100% bonus depreciation. Most §30C property is 5-year MACRS (charging equipment) or 15-year (qualified site improvements). Both eligible for 100% bonus under OBBBA-restored §168(k).
- File Form 8911 with your business return. Schedule A for commercial, residential on individual return. Pass-through entities pass §30C to owners on K-1.
- Document the census-tract eligibility. Save a PDF of the locator result showing the address, tract ID, and eligibility status. The audit will start here.
- Document PWA compliance. Certified payroll records (Davis-Bacon wage determinations) and apprentice hour logs. Without this paperwork, you fall to the 6% rate.
- Tax-exempt entities use direct pay (§6417). Municipalities, schools, and tribal entities receive the credit as a cash refund from Treasury — must register on the IRS pre-filing portal.
IRS code & authority
- §30C Alternative Fuel Vehicle Refueling Property Credit — 30% (with PWA), 6% (without PWA), capped at $1,000 (residential) / $100,000 (business) per item. OBBBA: property placed in service after June 30, 2026 is not eligible.
- §30C(c)(3) Eligible census tract definition — low-income community (§45D(e)) or non-urban (§147(b)(4)(B)).
- §45D(e) New Markets Tax Credit "low-income community" definition — used for §30C eligibility.
- §147(b)(4)(B) Non-urban area definition — population < 50,000 and not adjacent to an urban area.
- §30C(g) Prevailing wage + apprenticeship — the 5x credit multiplier.
- §50(c)(3) Basis reduction.
- §6417 Direct pay election for tax-exempt entities.
- §6418 Transferability — commercial §30C is transferable for cash.
- Form 8911 Alternative Fuel Vehicle Refueling Property Credit — Schedules A & B for commercial and transfer mechanics.
- Notice 2024-20 Census-tract guidance and the Argonne/Treasury §30C Locator.
- IRS Fact Sheet FS-2025-19 OBBBA modifications including §30C placed-in-service cutoff.
Audit risk flags
- Census tract ineligibility. The most common §30C audit issue — taxpayers install in a wealthy suburb assuming "EV charger = credit." Defense: Save the Argonne locator PDF dated before installation. If the project sits across multiple tracts, allocate.
- PWA claimed without records. Most contractors don't track certified payroll absent a federal contract. Defense: Make PWA compliance a contract requirement before signing; require monthly certified payroll submissions; keep apprentice logs.
- Per-item vs. per-location confusion. Some taxpayers cap themselves at $100K total when 12 chargers should be 12 caps. Defense: Treat each charger as its own depreciable property with its own basis and cap.
- Shared cost allocation overstated. Loading the transformer 100% onto chargers (where part of the upgrade may serve other building loads). Defense: Pro-rate the transformer/utility upgrade by demonstrated EV-related load.
- Bidirectional or V2G hardware misclassified. Battery storage isn't §30C — it's §48E. Defense: Separate the equipment on invoices and credits.
- Placed-in-service date after June 30, 2026. Permitting delays push commissioning past the OBBBA cliff. Defense: Plan with 60-day margin. Energize and commission before June 30, 2026 even if punch-list items remain.
- Residential install claimed at commercial cap. A homeowner with one Wall Connector cannot claim $30,000 of §30C — the residential cap is $1,000 per item. Defense: Match the cap to the property use.
When NOT to do this
- Your address isn't in an eligible census tract. No tract eligibility = no credit, no matter how much you spend. Verify before you wire money.
- Your install won't be commissioned by June 30, 2026. Backlogged permitting, transformer lead times of 9-18 months, and supply-chain delays are real. If you can't realistically energize by Q2 2026, the project earns no §30C.
- You can't or won't comply with prevailing wage. The 6% base rate is rarely worth the administrative overhead. Most projects only pencil at the full 30% with PWA.
- The charger is at a private residence not in an eligible tract. Residential §30C tract-eligibility is a real constraint — most metro suburbs are ineligible.
- You're installing standalone NEMA outlets. Outlets don't qualify; only dedicated EV charging equipment (EVSE) with utility-grade rating.
- Your business has no tax liability and isn't tax-exempt. Without direct pay (§6417) eligibility, an unused §30C credit carries forward but doesn't refund.
