Heat Pump Tax Credit 2026 — IRS Section 25C $2,000 Rules
Short answer: The 2026 IRS Section 25C credit pays 30% of installed cost up to $2,000 for qualifying heat pumps — air-source must meet CEE Advanced Tier + ENERGY STAR Cold Climate for northern states. No income limits. Annual cap (resets each year). Stack with $1,200 general efficiency credit (total Section 25C max $3,200/year). Geothermal heat pumps fall under Section 25D — 30% of ANY cost, no cap. Stackable with state + utility rebates: total household stack can hit $13,400 (MA), $10,400 (ME), $6,000 (NY/CA).

| Texas (Austin Energy) | $2,000 | $0 | $2,200 | $400 | $4,600 |
| Florida (no state rebate) | $2,000 | $0 | $600 | $400 | $3,000 |

Always verify the specific model number against ENERGY STAR\'s qualified product database (energystar.gov/productfinder) before installation. Manufacturers update product lines annually — what qualifies in 2026 may be different in 2027.
North vs South region — the cold climate distinction
For homes in the EPA-defined "North" region (typically above the 4,500 Heating Degree Day line — most of the northern US), the heat pump must additionally have ENERGY STAR Cold Climate certification. This certification verifies the heat pump:
- Maintains rated capacity at 5°F outdoor temperature
- HSPF2 ≥ 8.1 (heating season performance factor)
- Integrated COP at 17°F ≥ 2.4
- Variable-speed compressor (typically inverter-driven)
Southern region installations (Florida, Texas, Arizona, etc.) need only meet CEE Advanced Tier — Cold Climate certification is not required. However, many manufacturers ship cold-climate-certified models nationally; check the spec sheet.
How to claim the credit on your tax return
- Save the manufacturer's certification statement (heat pump model qualifies for Section 25C)
- Save all installer invoices showing labor + materials cost
- File IRS Form 5695 with your federal return (Energy Efficient Home Improvement Credit)
- Enter the heat pump cost on Part II Section A — check "Heat pump" box, enter cost (cap $2,000)
- If also claiming windows/insulation: complete other Part II sections
- Result flows to Schedule 3 line 5a, then 1040 line 20
- Keep paperwork for 7 years in case of audit (manufacturer cert + invoices)
