You installed a heat pump. Now you're doing your taxes and Form 5695 wants a "QMID." You've never heard of it. Your contractor didn't mention it. It's not on any of your paperwork.

That's normal. Most people hit this wall.

Quick Summary

QMID = Qualified Manufacturer Identification Number
4-character code the IRS assigns to registered manufacturers
Required on Form 5695 for all 25C claims (2025 tax year)
It's NOT on your invoice, equipment, or contractor paperwork
Look it up in our directory or call the manufacturer

What It Actually Is

QMID stands for Qualified Manufacturer Identification Number. It's a 4-character alphanumeric code that the IRS assigns to manufacturers who register their products for the 25C Energy Efficient Home Improvement Credit.

Example: Carrier QMID

Enter one character per box

The QMID is a 4-character alphanumeric code that identifies your equipment manufacturer. Enter it exactly as shown in the IRS database or our directory.

Think of it as a manufacturer's tax ID for the energy credit program. Carrier has one (N8H2). Daikin has one (I7Q6). Every qualified manufacturer has their own unique code.

The IRS uses it to verify that your equipment came from a manufacturer actually registered in the program. Before 2025, there was no verification step — you just claimed the credit. Now there is.

Credit Expired December 31, 2025

The 25C credit expired on December 31, 2025 due to the "One Big Beautiful Bill" (Public Law 119-21). If your equipment was installed by that date, you can still claim the credit on your 2025 return. (IRS FAQ)

Where to Get Your QMID

It's not on your invoice, your equipment, or any paperwork your contractor gave you. A QMID is an IRS registration code — it exists in the IRS system, not on a sticker on your furnace.

Two ways to get it:

1. Search our QMID directory. Type in the brand name on your equipment. We'll map it to the right manufacturer and give you the code. Takes a few seconds. We maintain this from crowd-sourced submissions and the IRS database.

2. Call the manufacturer. Ask them: "What's your QMID for the IRS 25C energy efficiency tax credit?" They'll know. They had to register with the IRS to get it.

You can also dig through the IRS's official list, but it's a large PDF and not easy to search.

The Brand Name Trap

This confuses almost everyone. The brand printed on your equipment is often not the name the IRS has on file.

Brand ≠ Manufacturer

The IRS registers QMIDs under parent companies, not retail brands. If your equipment says "Bryant," there's no Bryant in the IRS database — because Bryant is a Carrier brand.

Examples:

Bryant, Heil, Payne, Tempstar → all Carrier → QMID: N8H2
Goodman, Amana → both Daikin → QMID: I7Q6
American Standard → Trane → QMID: B8T9
Ruud → Rheem → QMID: K3A8

Our directory handles this automatically. Search "Bryant" and we'll tell you it's Carrier with QMID N8H2.

For the full list, see the brand-to-QMID lookup covering 30+ brands.

Where It Goes on Form 5695

The QMID goes on Part II, Section B, Line 29a of Form 5695. Four boxes, one character per box.

Enter one character per box

Different equipment types have different lines:

Heat pumps: Line 29a
Heat pump water heaters: Line 29c
Central AC: Line 22a
Gas/oil water heaters: Line 23a
Furnaces/boilers: Line 24a
Windows: Line 20a
Doors: Line 19b

All of them need a QMID starting with the 2025 tax year.

QMID vs. AHRI Number

These are different things. People mix them up.

AHRI number identifies a specific equipment model combination (outdoor unit + indoor unit). It's on your AHRI certificate and proves your equipment meets efficiency standards.

QMID identifies the manufacturer. It's the same code for every product that manufacturer makes.

You need both to claim the credit — the AHRI number proves your equipment qualifies, and the QMID proves the manufacturer is registered with the IRS.

What If My Manufacturer Isn't Listed?

Check the nameplate, not the logo. Open the service panel on your equipment. The actual manufacturer is printed on the metal data plate inside. It may be different from the brand on the front.
Search our full directory. We track 50+ manufacturers across HVAC, water heaters, windows, doors, and insulation.
Call the manufacturer directly. If they sell products that qualify for the 25C credit, they're required to have a QMID.
Submit a missing QMID. If you find one we don't have, add it so the next person doesn't have to hunt.

Note

For equipment installed in 2025 or later, the manufacturer must have a valid QMID for you to claim the credit. If they never registered, you can't claim the 25C credit for that equipment — though you may still qualify for utility rebates.
