The IRA Clean Energy Credit Calculator helps homeowners and businesses determine which Inflation Reduction Act tax credits and rebates they qualify for across solar, heat pumps, EVs, batteries, and energy efficiency improvements.
公式
Total Available Credits = Solar ITC (30%) + Heat Pump Credit ($2,000) + EV Credit ($7,500) + Efficiency Credits ($1,200/yr) + Electrification Rebates
- ITC

例题解析
输入
Solar system $24,000 + heat pump $8,000 + EV $45,000 + insulation $2,000
结果
Solar ITC: $7,200 + Heat pump: $2,000 + EV: $7,500 + Insulation: $1,200 = $17,900 total credits
输入
Heat pump water heater $2,500 + electrical panel upgrade $4,000
结果
HP water heater: $2,000 credit + panel: $600 credit = $2,600 (within $3,200 electrification cap)
常见错误注意事项
- ✕Not realizing the $1,200 annual cap on 25C efficiency credits resets each year — spread improvements across tax years
- ✕Confusing the heat pump $2,000 credit (separate from the $1,200 efficiency cap) with the general efficiency credits
- ✕Missing that low-to-moderate income households qualify for separate HOMES and HEAR rebate programs up to $14,000
常见问题
How much can I save total with IRA clean energy credits?
A homeowner doing solar ($7,200), heat pump ($2,000), EV ($7,500), and efficiency upgrades ($1,200/yr) could claim $18,000+ in federal tax credits. Low-income households may qualify for an additional $14,000 in rebates.
How long do IRA clean energy credits last?
