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."

Credit: 30% · $1K cap residential · $100K cap commercial/item Difficulty: ★★☆☆☆ Audit Risk: Medium (census-tract verification) Status: ⚠ Must be placed in service by June 30, 2026 (OBBBA)

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

Greenline Logistics · Last-mile delivery fleet · Lehigh Valley, PA

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

  1. 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.
  2. 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.
  3. 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.
  4. Decide commercial vs. residential. Same code section, different caps: $1,000 cap per item residential (individuals); $100,000 cap per item commercial (business).
  5. 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.
  6. 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.
  7. Reduce depreciable basis by the credit (§50(c)(3)). $144K credit on $480K project → depreciable basis is $336K.
  8. 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).
  9. 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.
  10. 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.
  11. Document PWA compliance. Certified payroll records (Davis-Bacon wage determinations) and apprentice hour logs. Without this paperwork, you fall to the 6% rate.
  12. 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.
