Home Battery Payback: Who Still Gets the 30% Credit?

A bought battery gets $0 federal credit in 2026 and a third-party-owned one carries the 30% §48E — size and price the backup you need below.

Where the 30% actually went

This trips up almost everyone, so it’s worth being precise about which credit is which.

The credit homeowners used for years was §25D, the residential clean energy credit. It paid 30% of the cost of solar and of a qualifying battery, straight off your tax bill, and you claimed it yourself. The 2025 budget law ended it for property placed in service after December 31, 2025. There is no phase-down and no grace period for a cash or financed purchase — it is $0.

The 30% you still hear quoted lives in §48E, the clean electricity investment credit. That is a business credit, claimed by whoever owns the equipment and puts it into service. It never applied to a homeowner buying their own battery, and it still doesn’t.

What changed in 2025 is the timing on the business side. The law pulled the termination dates for wind and solar sharply forward, but energy storage was handled separately and keeps running longer than solar does. That asymmetry is the whole reason a salesperson can accurately say “storage still gets 30%” while being useless to you as a buyer — they are describing their own tax position, not yours.

So there are exactly two ways a homeowner touches that 30% in 2026:

• You don’t own the battery. A lease, a PPA, or a provider-owned VPP battery means the company claims §48E. Whether any of that value reaches your monthly fee is a pricing question, not a tax one — and the only way to find out is to compare quotes.
• You own it, and your state helps. The federal side is $0, but state and utility programs are unaffected by the federal change. Those are where a purchase’s real discount comes from now.

Two things to verify rather than take from any website, this one included: the exact §48E phase-down schedule for storage, which turns on begin-construction and placed-in-service tests that have moved more than once, and whatever your state currently offers, since those programs open and close on their own timetables. Check DSIRE for state programs and a tax professional for your own return. Nothing here is tax advice.

The number that decides it: your rate spread

Strip the tax question away and battery payback comes down to one subtraction on your utility bill:

• What you pay for grid power at peak times — time-of-use peaks reach 40–70¢/kWh in the worst territories.
• What you’re credited for exporting solar — under net billing like NEM 3.0 , often around 8¢/kWh.

Every kWh you store and use yourself instead of exporting is worth that difference, not the full retail rate. At 40¢ import and 8¢ export, shifting 12 kWh a day is worth roughly $1,400 a year. At 18¢ import and 17¢ export — a typical full-retail net metering setup — the same battery doing the same work saves about $44 a year.

That is the entire story of why battery advice is so contradictory. Someone in California under NEM 3.0 and someone in a full-retail net metering state are describing genuinely different investments, and both are right about their own bill.

What the third-party route costs you that a spreadsheet won’t show

If the numbers push you toward a lease or provider-owned battery, price the non-financial terms too, because that’s where these deals go wrong:

• The escalator. A 2.9% annual increase on a $95 fee is $95 today and about $124 in year ten. The tool applies whatever escalator you enter — take the real one from the contract, not the sales sheet.
• Who decides when it discharges. In most VPP arrangements the provider can call on your battery during grid events. That’s the deal, and usually fine, but it means the battery isn’t purely yours during the hours you’d most want it.
• What happens when you sell the house. Transferring or buying out a 20-year contract is a routine friction point in home sales. Ask how it works before signing, not after listing.
• Escape terms. Buyout pricing and early-termination costs vary widely and are rarely volunteered.

None of this makes third-party ownership a bad route — for a household with no tax appetite and no appetite for $15,000 upfront, it is often the only route. It just isn’t the free money that “you still get the 30%” implies.

What this tool deliberately doesn’t price

• Backup power. Riding through an outage with the fridge and the internet running is real value, and for some households it’s the entire reason to buy. It has no clean dollar figure, so the tool leaves it out rather than invent one.
• Rate changes. Your peak rate and export credit will both move over a battery’s life, and net billing rules are being rewritten in several states. The math above holds today’s numbers still.
• Degradation beyond the simple case. A flat ~1%/year fade is a reasonable planning assumption, not a warranty term. Read yours.
