Arkansas geothermal incentives in 2026
The federal §25D Residential Clean Energy Credit was terminated for new residential expenditures completed after December 31, 2025 by the One Big Beautiful Bill Act (P.L. 119-21). 2025 installations carry forward via IRS Form 5695. Arkansas homeowners benefit from:
- Entergy Arkansas + SWEPCO + Arkansas Electric Cooperatives — Entergy Arkansas Energy Solutions and SWEPCO energy efficiency rebate programs.
- Federal §48 commercial credit remains active through 2034 with phase-down; widely used in third-party-owned residential leases.

Arkansas climate is humid subtropical (Cfa) statewide. Ground temperatures at typical loop depth stay around 60–64°F. Coastal Plain sandy sediments south and east, Ozark Plateau limestone in the northwest, Ouachita Mountains in the west. Conditions vary by region.

For permit specifics see our geothermal permit lookup.
Frequently asked questions
How much does geothermal cost in Arkansas?
A typical 3-ton residential system in Arkansas runs $20,000 to $34,000 installed depending on loop type, soil conditions, and location. Utility rebates from Entergy Arkansas + SWEPCO + Arkansas Electric Cooperatives reduce out-of-pocket cost. Federal §25D no longer applies to 2026 residential installations.
Do I need a permit for geothermal in Arkansas?
Yes. Closed-loop installations require a Arkansas Natural Resources Commission (ANRC)-certified well driller, a state-licensed mechanical contractor, and a local building permit covering the indoor unit and electrical service. Reputable Arkansas contractors handle the full permit pull.
Vertical or horizontal loops in Arkansas?
Lot size and soil determine loop type. Vertical bores dominate dense suburbs; horizontal loops are cost-competitive on rural lots with adequate land area (1,500–3,000 sq ft per ton). Pond loops work where adequate water access exists. An IGSHPA-trained designer matches loop type to your specific lot, soil, and load.
