Introduction – What is Publication 6028?
IRS Publication 6028, titled “Businesses and the Alternative Fuel Vehicle Refueling Property Credit,” is an official IRS guidance publication designed to help businesses navigate the tax incentives available under Internal Revenue Code Section 30C. It explains how commercial enterprises can reduce their federal tax burden when purchasing and installing clean-fuel refueling stations and commercial electric vehicle (EV) charging infrastructure.
According to official IRS release schedules and records, the latest updated edition of Publication 6028 carries a formal Revision Date of May 2026 and was officially posted to the IRS portal on June 1, 2026 (with its accompanying Spanish-language edition released on June 11, 2026). This 2026 release incorporates essential clarifications following the Inflation Reduction Act amendments, providing clear instructions on eligible equipment, credit percentages, wage rules, and geographic census tract requirements.
Who Should Read This Publication
Publication 6028 is written specifically for business owners, corporate tax managers, fleet operators, and commercial property developers. Whether you run a single retail storefront or operate a nationwide logistics fleet, adding EV charging ports or alternative fuel dispensers can qualify for significant tax relief.
The guide is also essential reading for tax practitioners, accountants, and commercial contractors installing clean energy hardware. Tax-exempt entities and non-profits planning similar projects may also benefit from its baseline formulas, though they typically refer to companion guides such as Publication 6029 for elective pay rules.
Key Topics Covered
Publication 6028 breaks down complex energy tax regulations into manageable rules that any business owner can understand. Key areas covered include:
- Credit Percentages and Base Rates: The difference between the 6% standard rate and the 30% enhanced rate.
- Per-Item Dollar Limits: How the $100,000 statutory cap applies to individual charging ports or dispensers.
- Eligible Fuels and Equipment: Which technologies qualify, including Level 2 chargers, DC fast chargers, and hydrogen refueling pumps.
- Geographic Eligibility: The requirement that installed property must reside in an approved low-income or non-urban census tract.
- Prevailing Wage and Apprenticeship (PWA) Standards: Labor rules required to unlock the top-tier 30% incentive.
Detailed Breakdown of Main Concepts
1. Credit Rates and Dollar Caps
The Section 30C business tax credit provides a baseline tax offset equal to 6% of the depreciable project cost. However, if your business satisfies strict prevailing wage and registered apprenticeship requirements during construction and installation, the credit rate jumps to 30%.
Rather than capping the credit at a lump sum for the whole site, the law applies a generous per-item limit. For depreciable commercial property, you can claim up to $100,000 for each single item of refueling property installed, such as each separate charging port or fuel dispenser.
| Requirement Level | Credit Percentage | Maximum Cap Per Single Item |
|---|---|---|
| Standard Base Credit | 6% of eligible costs | $100,000 |
| With Prevailing Wage & Apprenticeship | 30% of eligible costs | $100,000 |
2. Eligible Alternative Fuels and Hardware
The credit is not limited solely to passenger EV charging. It applies broadly to equipment used to store or dispense alternative fuels into the fuel tank or battery of a motor vehicle. Qualifying energy sources include electricity, hydrogen, natural gas (CNG and LNG), liquefied petroleum gas (propane), and clean fuel blends containing at least 85% ethanol or biodiesel.
Eligible property includes charging pedestals, power conversion units, dispensing nozzles, electrical wiring directly tied to the equipment, and bidirectional vehicle-to-grid equipment. Stationary electrical energy storage technology integrated with charging stations can also qualify.
3. Census Tract Location Rules
To qualify for the credit, the refueling property must be placed in service within an eligible census tract. The IRS defines an eligible tract as either a population census tract qualifying as a low-income community under the New Markets Tax Credit guidelines or a tract located in a non-urban area.
Businesses must verify their installation address against IRS census tract mapping tools before claiming the credit. If a property is located in an ineligible urban or higher-income area, the installation costs do not qualify for the Section 30C credit.
Practical Examples or Scenarios
Scenario A: Retail Center Installing Fast Chargers
A regional shopping center located in an eligible low-income census tract spends $200,000 installing two DC fast-charging ports ($100,000 per port, including electrical upgrades). The contractor complies with all prevailing wage and registered apprenticeship requirements. Because the center meets PWA rules, it qualifies for the full 30% rate, resulting in a tax credit of $60,000 ($30,000 per port).
Scenario B: Delivery Fleet Installing Standard Chargers
A delivery company installs five commercial Level 2 charging ports at its distribution depot located in an eligible non-urban tract. Total installation costs come to $50,000 ($10,000 per charging port). The company opts not to document prevailing wage requirements, claiming the baseline 6% rate instead. The resulting credit equals $3,000 ($600 per port), well below the per-item ceiling.
How This Publication Relates to Specific Forms
Publication 6028 serves as the instructional companion to several official tax forms filed with your annual business income tax return:
- Form 8911 (Alternative Fuel Vehicle Refueling Property Credit): This is the primary form used to calculate the credit amount and document equipment details.
- Form 3800 (General Business Credit): Because Section 30C is part of the general business credit, the calculated credit transfers to Form 3800 to determine limitations and carryforwards.
- Form 1120 / Form 1120-S / Form 1065: Corporate returns incorporate the final credit, while pass-through partnerships report each owner’s share on Schedule K-1.
- Form 1040 (Schedule C): Sole proprietors report their business expenses and claim the resulting credit against their net income tax.
Common Misunderstandings Clarified
Many business owners mistakenly believe that the $100,000 limit is a total cap for an entire commercial address. In reality, the limit applies per single item of refueling property, meaning a multi-port charging plaza can claim multiple caps if costs warrant it.
Another frequent misunderstanding involves location eligibility. Many taxpayers assume any commercial site is eligible; however, if your physical business address does not sit inside an officially recognized rural or low-income census tract, the property cannot qualify. Always check the official IRS mapping tools first.
Why This Publication Matters for Taxpayers
Transitioning corporate fleets or customer parking spaces to clean energy represents a substantial upfront capital expenditure. Publication 6028 provides clarity that allows business owners to project accurate return-on-investment timelines and minimize compliance errors.
By understanding labor criteria ahead of construction, companies can capture an extra 24% in tax credits. Taking full advantage of these rules frees up business capital, promotes sustainability, and ensures smooth processing during IRS audits.
Frequently Asked Questions
Can home-based businesses use Publication 6028?
If you run a home-based business and install a charger used purely for business vehicles, it may qualify under commercial depreciable rules. However, personal home chargers fall under residential rules covered in Publication 6027, which carry a lower $1,000 limit.
What does “placed in service” mean?
A refueling station is placed in service when it is completely installed, operational, and ready to provide charging or alternative fuel dispensing, even if customers have not used it yet.
Can I sell or transfer this tax credit to another party?
Under Section 6418 rules enacted alongside the credit, certain eligible businesses may elect to transfer their general business credits to an unrelated third party for cash. Consult your tax professional regarding credit transfer guidelines.
Conclusion
IRS Publication 6028 is an indispensable handbook for any business investing in electric vehicle charging or clean alternative fueling stations. With its comprehensive 2026 revisions detailing eligible hardware, census tract validations, and wage thresholds, this guide gives business operators the confidence to invest in clean energy while maximizing their tax savings.
