What this line means
The maximum credit allowed based on the annual limits. The overall cap is $3,200 per year, composed of two buckets: up to $1,200 for building envelope components (insulation, windows, doors, skylights) plus up to $2,000 for heat pumps, biomass stoves, and heat pump water heaters. These limits reset annually — you can claim the full $3,200 every year you make qualifying improvements. 1
Does this apply to you?
- You entered improvement costs on lines 15 through 17a of Form 5695
- You need to determine the maximum credit before applying the tax liability limitation
- You are calculating how much of your spending qualifies within the annual sub-limits
Easy to overlook
Annual limits reset every January 1 Unlike the old lifetime limit that applied before 2023, the current credit resets each year. If you claimed $3,200 last year, you can claim another $3,200 this year for new improvements. There is no cumulative cap. A homeowner who replaces windows one year and installs a heat pump the next gets credits both years. 2 Inflation Reduction Act Section 13301 — Energy efficient home improvement credit
The two buckets are independent Spending $800 on insulation does not reduce your $2,000 heat pump allowance. The $1,200 envelope bucket and the $2,000 heat pump bucket operate separately. You do not need to choose between them — install insulation and a heat pump in the same year and claim from both buckets. 1 IRS Form 5695 instructions — Line 24
Watch out for this
Do not confuse this line with your final credit. Line 24 shows the maximum based on spending limits, but line 30 is your actual credit after the tax liability limitation. If your tax bill is lower than the credit on line 24, your actual credit on line 30 is reduced — and the Part II credit does not carry forward. Any amount above your tax liability is lost.
Plan your improvements strategically. If you have $6,400 worth of qualifying work planned, splitting it across two tax years (claiming $3,200 each year) gets you more credit than doing everything in one year and bumping against the cap. 1
