What is DC Alternative Fuel Vehicle Residential Credit Form (PDF)?
The Alternative Fuel Vehicle Infrastructure and Conversion Residential Form is the DC Office of Tax and Revenue (OTR) form used to calculate and claim credits for alternative fuel vehicle (AFV) charging or fuel storage dispensing stations and vehicle conversions. The PDF itself is headed "Residential Form, Alternative Fuel Vehicle Conversion and Infrastructure Credits" and prints the revision "Revised 10/2017"; OTR lists this file as its 2025 version.
The form has four blocks of lines:
- A. Personal information: your name, telephone number and email.
- B. AFV charging or fuel storage dispensing station – Private residence: equipment, manufacturer, invoice number and lines B1 to B5, plus the residence address.
- C. AFV charging or fuel storage dispensing station – Public use: the same cost lines as C1 to C5, the installation address, access, hours of operation and accepted payment methods.
- D. Vehicle lines: the AFV manufacturer and model, with lines D1 to D5.
On every credit block you add equipment cost and labor cost, multiply the total by the factor printed on the form, and enter a credit amount that does not exceed the cap printed on that line. The credit claimed in any one tax year cannot exceed the income tax liability. Because the credit is claimed with Form D-40, this is an income tax credit form and not a DC property tax form. The form is a fill-in format: apart from your signature, nothing is to be handwritten.
Who needs to file DC Alternative Fuel Vehicle Residential Credit Form (PDF)?
Taxpayers who are claiming the alternative fuel vehicle credit on their Form D-40 use this form. According to the blocks printed on it, that covers three situations:
- You installed an AFV charging or fuel storage dispensing station at a private residence (block B).
- You installed a station for public use (block C), which requires an installation address that is not a PO Box.
- You modified an existing petroleum derived gasoline or diesel fuel vehicle to run on an alternative fuel, and you list the AFV manufacturer and model (lines D1 to D5).
The form is returned with Form D-40 only "if claiming the credit", so you do not complete it if you are not claiming the credit. Because the credit claimed in any one tax year cannot exceed the income tax liability, the amount you can use depends on your D-40. The signer affirms under penalties of law that the information is in accordance with all applicable laws, regulations and permitting requirements, that the equipment is operational and that there are no false statements. The form does not describe a representative signing for you; it has a single signature block for the person claiming the credit.
When to file DC Alternative Fuel Vehicle Residential Credit Form (PDF)
Complete this form when you claim the alternative fuel vehicle credit, because the form says to return it with Form D-40 if you are claiming the credit. No separate due date is printed on it, so it travels with your D-40 whenever that return is submitted. OTR's page presents this PDF as the 2025 version of the form.
Have the paid invoices and the electrical permit ready before you start, since photocopies must accompany the form. Your signature affirms that the equipment is operational, so the installation should be finished when you sign. The credit claimed in any one tax year cannot exceed the income tax liability; check the D-40 instructions and OTR for any other timing rule that applies to the return itself.
Documents you need
- A photocopy of a paid invoice, receipt or equivalent proof of payment for modifying the existing petroleum derived gasoline or diesel fuel vehicle, when you claim a vehicle conversion.
- A photocopy of a paid invoice, receipt or equivalent proof of payment for the purchase and installation of qualified alternative fuel storage and dispensing or charging equipment, when you claim a station.
- A photocopy of an electrical permit, listed on the form among the documents to attach.
- Form D-40, the return with which this form is returned if you are claiming the credit.

- Entering a credit amount above the cap printed on lines B5, C5 or D5 instead of the lower of the cap and the calculated amount.
