Insulation & Air Sealing rebates & tax credits in Tennessee

Total potential savings on a $3,800 insulation & air sealing: $2,740. That breaks down as $1,140 federal tax credit (25C Energy Efficient Home Improvement Credit), and up to $1,600 IRA HEEHRA point-of-sale rebate (income-qualified only). Net out-of-pocket: $1,060 (best case) to $2,660 (without HEEHRA).

Tennessee HEEHRA status: PENDING. ○ Plan approved by DOE, consumer rebates not yet active. Federal tax credits are available now via your 2026 return; HEEHRA point-of-sale rebates not yet redeemable. The federal 25C/25D tax credit IS available to Tennessee residents in 2026 — file with your tax return. HEEHRA point-of-sale rebates will start once Tennessee launches its program.

No — 25C, 25D, and 30C are credits, not deductions. You claim them on Form 5695 (Residential Energy Credits) regardless of whether you itemize. Catch: they're NON-refundable. If your federal tax liability is smaller than your credit, the excess rolls forward (5 years for 25D solar; 25C does NOT roll forward — use it or lose it that year). Plan your install for a year when your tax bill is at least equal to the credit.

Yes — this is the single most common abuse in the post-IRA market. The clearest red flag: a quote that's higher than your state's typical range for insulation & air sealing by exactly the amount of the rebate. Always: (1) get the quote BEFORE mentioning rebates, (2) cross-check against Tennessee fair-price data, (3) refuse "rebate handling fees" — HEEHRA point-of-sale is supposed to be applied without additional contractor markup.
