How it works

Three steps to your rebate stack

Step 1

Enter your three project costs

Solar, charger, and EV are separate purchases with separate incentive programs, so keep the costs listed separately for the most accurate stack.

Step 2

Confirm your federal eligibility

The federal new EV purchase credit ended for vehicles acquired after September 30, 2025. If you claimed it before that date, enter the amount here for context. Otherwise, leave it blank and check current state and utility EV incentives instead.

Step 3

Add your state and utility programs

Search DSIRE for state-specific solar and EV incentives, and check your utility's website directly for charger rebates they don't always list elsewhere.

Understanding incentive stacking for solar plus EV

Why stacking incentives usually works, but not always

Federal, state, and utility incentive programs are generally administered by different agencies with their own independent eligibility rules, so claiming a solar tax credit doesn't typically disqualify a separate EV or charger credit. That said, some state rebate programs explicitly exclude households who've already received a different state incentive for the same equipment, so read program rules carefully rather than assuming every combination stacks freely.

The federal solar credit has no price cap; the EV credit no longer exists

The federal residential clean energy credit for solar applies a flat percentage to the full system cost with no maximum claim amount, and remains active. The federal new EV purchase credit, by contrast, included both an income cap for the buyer and a price cap on the vehicle itself, with different caps for cars versus trucks and SUVs, but the credit itself ended for vehicles acquired after September 30, 2025 under the One Big Beautiful Bill Act. If you're planning a purchase now, that federal piece of this stack is no longer available, so verify current state and utility EV incentives against fueleconomy.gov's current guidance instead.

The charger credit also ended, as of mid-2026

The federal Alternative Fuel Refueling Property Credit for home EV charging equipment covered a percentage of installation cost up to a fixed dollar cap, separate from both the solar and EV vehicle credits, but it ended for property placed in service after June 30, 2026. If your charger installation was completed before that date, it's worth confirming with a tax professional whether you can still claim it; for a new installation now, this piece of the stack no longer applies.

Timing your purchases can affect which incentives apply

Incentive programs change from year to year, sometimes mid-year, so a rebate available when you request a quote may differ by the time your installation is complete. Confirm the exact program terms and application deadlines, using the rebate deadline tracker tool, close to your actual purchase date, not just when you first started planning.

Building on this result

Take your net project cost to the EV solar payback calculator to see how quickly the reduced cost pays for itself, or to the EV solar financing calculator if you're financing the remaining balance rather than paying cash. Home solar charging only wins if it beats the grid price. The levelized cost of energy calculator in our Savings & Payback section can help you compare the two over the life of the system.

Questions

Frequently asked

These are separate incentive programs with their own eligibility rules, so claiming one doesn't disqualify you from the others. The federal solar credit and federal charger credit both remain active, but the federal new EV purchase credit ended for vehicles acquired after September 30, 2025, so a household purchasing today can generally only claim the first two at the federal level, plus any state or utility EV incentives that still apply.

The federal new EV credit, while it was active, included both a buyer income cap and a vehicle price cap that varied by vehicle type. The credit itself ended for vehicles acquired after September 30, 2025, so this no longer applies to a new purchase. Confirm current state and utility EV incentive rules on fueleconomy.gov or your state's energy office instead.

The federal Alternative Fuel Refueling Property Credit for home EV chargers was capped at a percentage of cost up to a fixed dollar maximum, but the credit itself ended for property placed in service after June 30, 2026. Check IRS.gov for current status and whether any successor program exists.

Generally a state or utility rebate paid directly to you does not reduce your federal credit basis, but a rebate applied as an upfront discount by your installer sometimes does, since the federal credit is calculated on your actual out-of-pocket cost. A tax professional confirms which rule applies to your specific rebate structure.
