Tax Credits and Deductions for Home Improvements in Tennessee: Federal and State Guide
Tennessee homeowners can claim valuable federal tax credits for qualifying energy-efficient and clean energy home improvements—but the state offers no income tax credit due to its complete Hall Income Tax phase-out in 2021. Instead, local property tax relief programs—like homestead exemptions and elderly/disabled deferrals—may reduce tax burdens after qualifying upgrades. Accountants must understand IRS Form 5695 requirements, Tennessee’s lack of state-level energy incentives, and how local assessors treat improvements to avoid unintended property tax increases.
Federal Energy Efficient Home Improvement Credit (Section 25C)
The Energy Efficient Home Improvement Credit (IRC §25C), extended through 2032 by the Inflation Reduction Act, allows Tennessee taxpayers to claim 30% of qualified expenses—up to $3,200 annually—for exterior windows, doors, insulation, central air conditioners, heat pumps, water heaters, and biomass stoves meeting strict ENERGY STAR or DOE criteria. Eligible improvements must be installed in the taxpayer’s principal residence located in Tennessee and placed in service after January 1, 2023. Unlike prior versions, the credit is now available each year (not just once), with separate $1,200 caps for building envelope components and $2,000 for heat pumps and related equipment. Documentation must include manufacturer certifications, receipts, and installation dates; contractors are not required to be licensed in TN for eligibility, but the taxpayer bears full substantiation responsibility. Importantly, this credit is nonrefundable and reduces federal income tax liability dollar-for-dollar—so it provides no benefit if the taxpayer owes no federal tax. Accountants should verify that improvements meet current IRS Notice 2023–35 specifications and confirm the home is not a rental or second residence, as those are ineligible.
Residential Clean Energy Credit (Section 25D)
The Residential Clean Energy Credit (IRC §25D) provides a 30% federal tax credit for qualified solar, wind, geothermal, fuel cell, and battery storage installations placed in service after December 31, 2021, with no annual cap and available through 2032. In Tennessee, this applies to rooftop solar PV systems, ground-mounted residential wind turbines (under 100 kW), geothermal heat pumps meeting EPA ENERGY STAR standards, and battery storage (≥3 kWh) charged exclusively by renewable sources. The credit covers labor costs, permitting fees, and interconnection charges—critical for TN homeowners navigating TVA or municipal utility requirements. Unlike 25C, 25D applies to both principal residences and second homes (but not rentals), and unused credit may be carried forward indefinitely. Tennessee has no state-level clean energy credit, and the Hall Income Tax repeal means no offsetting state tax benefit. Accountants must ensure Form 5695 Part II is completed accurately, cross-checking equipment certification databases (e.g., DSIRE) and confirming system ownership—not leasing—since third-party owned systems disqualify the homeowner. Also note: TN law prohibits local governments from imposing property tax increases solely due to solar installations under Tenn. Code Ann. § 67-5-202(d), protecting assessed value stability.
Tennessee State and Local Property Tax Relief Programs
While Tennessee imposes no state income tax on wages and fully phased out the Hall Income Tax on investment income effective January 1, 2021, it relies heavily on property taxes—and offers several local relief mechanisms relevant to home improvement decisions. The Homestead Exemption reduces assessed value by up to $40,000 for qualifying owner-occupants aged 65+, disabled, or surviving spouses, administered county-by-county (e.g., Davidson County requires application by March 1). The Elderly/Disabled Property Tax Deferral Program (Tenn. Code Ann. § 67-5-701 et seq.) allows eligible residents to defer payment (with low interest) until sale or transfer—crucial when energy upgrades increase appraised value. Notably, Tennessee law (§ 67-5-202(d)) explicitly excludes solar energy systems from property tax assessment increases, and many counties—including Knox, Shelby, and Hamilton—extend similar exclusions to geothermal and battery storage. However, standard HVAC replacements or window upgrades may trigger reassessment unless grandfathered under local ordinances. Accountants should advise clients to consult their county assessor before major improvements and file exemption applications proactively, as deadlines and documentation vary widely across Tennessee’s 95 counties.
Compliance, Reporting, and Common Pitfalls for Accountants
Tennessee accountants must ensure strict compliance with IRS Form 5695 filing requirements—including accurate allocation of shared expenses (e.g., heat pump + ductwork), proper use of Part I (25C) vs. Part II (25D), and avoidance of double-dipping with utility rebates (which reduce the credit base per IRS Pub. 936). A frequent error is misclassifying non-qualifying items: smart thermostats alone don’t qualify under 25C unless paired with an eligible HVAC system, and roofing materials—even energy-efficient ones—are excluded unless part of a certified solar shingle system under 25D. Tennessee-specific pitfalls include assuming local property tax freezes apply broadly (they do not—only solar is statutorily protected), overlooking county-level homestead filing deadlines, and failing to document that improvements were made to the taxpayer’s principal residence (verified via utility bills or deed). Additionally, while TN has no state tax form mirroring Form 5695, accountants must still track credit carryforwards and coordinate with property tax filings. Finally, remind clients that energy audits themselves are not credit-eligible unless they directly lead to installation of qualifying equipment—and only the installation costs count, not diagnostic fees.

Does Tennessee offer any state-level tax credit for solar or energy-efficient home improvements?
No. Tennessee repealed its Hall Income Tax in 2021 and does not offer a state income tax credit for energy improvements. There is no equivalent to Form 5695 at the state level. However, Tennessee law (TCA § 67-5-202(d)) prohibits property tax increases solely due to solar installations—a meaningful valuation protection distinct from a tax credit.
If a client installs a heat pump in Nashville in 2024, which credit applies—25C or 25D—and what’s the maximum benefit?
A qualifying air-source or geothermal heat pump installed in a principal residence qualifies under IRC §25C (not 25D), with a $2,000 annual credit cap. The taxpayer may claim 30% of total installed cost—up to $2,000—if the unit meets DOE efficiency standards and is placed in service in 2024. Labor, permits, and electrical upgrades directly tied to the heat pump are includible.
How does the Homestead Exemption interact with a home improvement that increases market value in Shelby County?
The Homestead Exemption in Shelby County reduces assessed value by up to $40,000 but does not freeze the underlying appraised value. If an energy upgrade increases the home’s appraised value, the exemption is applied *after* reassessment—so the taxpayer still benefits from the exemption amount, but the base value subject to taxation may rise. Filing the exemption by the March 1 deadline is mandatory to secure the reduction for that tax year.
