No federal 30C credit is auto-applied in the current build.
Planning boundary: amperage is configuration context; the cost model uses the dollar inputs you provide. Permit, panel work, trenching, detached-building work, load management and rebates vary by address and are not invented from a statewide average. Service headroom is a planning flag, not an electrical-code load calculation.
$0 in this current build for new personal installations after June 30, 2026.
why Massachusetts differs
Massachusetts installation assumptions
The labor-rate default uses a transparent regional wage index: Boston-Cambridge-Newton all-occupation mean hourly wage, May 2025 ($43.09/hr) divided by the U.S. all-occupation mean wage used in the same BLS release context ($33.54/hr), applied to a $100/hr editable national service-rate assumption. It is a planning model, not a contractor bid.
Electrical permitting and inspection requirements are local. CalcuRiver does not encode one statewide permit fee.
No universal statewide residential charger rebate is auto-applied. Utility/local incentives must be entered only when the user confirms eligibility.
Permit fees, electrician bids, trenching, detached-building work, service upgrades, load-management requirements and utility rebates can vary by address. CalcuRiver keeps those inputs editable instead of manufacturing a statewide “average quote.” The low/base/high figures are planning scenarios, not contractor estimates.

Local permitting examples in this state
These official jurisdiction examples improve planning context without inventing a statewide permit fee or contractor quote. Confirm the exact address and project scope before relying on a local process.
verified local example
City of Boston
Permit: Required. Electrical installation and alteration work is covered by Boston's electrical permit process; only licensed contractors may apply.
Review / service: Required documents and fees depend on project scope. CalcuRiver does not infer a permit total from the city fee schedule. Boston publishes a service/new-service fee structure based on amperage, but CalcuRiver leaves the permit input editable because applicability depends on the actual project.
Installation cost is most sensitive to charger equipment, wiring distance, labor, permit requirements, available electrical-service headroom, trenching and any panel or load-management work. Local rebates are counted only when the user confirms them.
