South Dakota Heat Pump Rebates & Tax Credits (2024-2026)

Quick Answer: South Dakota Heat Pump Savings

If you are installing a heat pump in South Dakota, here are the current financial incentives:

Federal tax credit (available now): IRS §25C provides a 30% credit on qualifying heat pump costs, capped at $2,000 per year. This applies to air-source heat pumps, ground-source (geothermal) systems, and heat pump water heaters. Claim it on IRS Form 5695 when you file.

Federal rebates (rolling out): The Inflation Reduction Act created two rebate programs, HOMES (IRA §50122) and HEAR (IRA §50123), which can deliver up to $8,000 for a qualifying heat pump HVAC system. These are state-administered, and South Dakota's rollout is in progress. Consult the South Dakota Public Utilities Commission or relevant state agency for current availability before planning around these funds.

Utility programs (available now): Otter Tail Power Company offers residential rebates for geothermal and air-source heat pumps. Southeastern Electric Cooperative provides low-interest loans for heat pump installations through its partnership with the Rural Electric Economic Development (REED) Fund.

Property tax relief: South Dakota's Renewable Energy System Exemption, administered by the S.D. Department of Revenue, exempts real property used or constructed for qualifying geothermal and solar energy facilities under 5 MW from certain property taxes.

Key advantage: Federal tax credits (§25C) stack with utility rebates and state property tax incentives. The one restriction is that HOMES and HEAR rebates cannot both apply to the same measure. Plan your project to layer multiple programs.

Federal Heat Pump Tax Credits and Rebates for South Dakota Homeowners

IRS §25C Energy Efficient Home Improvement Credit

This federal incentive is immediately accessible, independent of state program rollout. The credit equals 30% of your qualifying heat pump installation costs, up to $2,000 per year for heat pumps (IRS §25C). The annual cap resets each tax year, allowing claims in successive years for separate installations.

Qualifying equipment includes:

• Air-source heat pumps meeting CEE Tier requirements or ENERGY STAR Most Efficient designation
• Ground-source (geothermal) heat pumps meeting applicable efficiency standards
• Heat pump water heaters meeting ENERGY STAR Most Efficient criteria

Your installer must provide an AHRI (Air-Conditioning, Heating, and Refrigeration Institute) certificate confirming the equipment meets the required efficiency ratings. Without that documentation, your credit is at risk during an audit. Claim using IRS Form 5695; consult IRS instructions for Form 5695 for current line-by-line guidance.

Separate caps within §25C: $600 for electrical panel or breaker upgrades, $150 for a home energy audit. These do not reduce your $2,000 heat pump cap.

IRA §50122 HOMES Rebate Program

The HOMES program offers performance-based rebates tied to the energy savings achieved after home improvements (IRA §50122). The maximum rebate is $8,000 for households achieving a modeled energy reduction of 35% or more. Lower savings thresholds qualify for smaller rebates.

Income scaling applies. Low-to-moderate income (LMI) households receive double the standard rebate amounts. This program is administered at the state level, so the actual application process and launch date depend on South Dakota's implementation. Consult the South Dakota Public Utilities Commission or relevant state agency for current status.

IRA §50123 HEAR (High-Efficiency Electric Home Rebate) Program

HEAR is a point-of-sale rebate, meaning the discount comes off your purchase price rather than arriving as a tax credit later (IRA §50123). Maximum rebates are:

Income cap: your household must be at or below 150% of Area Median Income (AMI) to qualify. This program is also state-administered. Consult the South Dakota Public Utilities Commission or relevant state agency for launch status.

Equipment Standards and AHRI Certificates

Both §25C and the IRA rebate programs require specific efficiency ratings. For air-source heat pumps, look for CEE Tier or ENERGY STAR Most Efficient certification. For geothermal systems, ENERGY STAR certification applies. Ask your contractor to pull the AHRI certificate for the specific model before you commit to a purchase. The certificate number ties the equipment to its rated performance and is your primary documentation for any rebate or credit claim.

South Dakota State and Local Utility Heat Pump Incentives

Otter Tail Power Company Rebate Program

Otter Tail Power Company offers a Residential and Commercial Energy Efficiency Rebate Program for its South Dakota customers. Rebates are available for geothermal heat pumps and air-source heat pumps, along with electric water heaters and other efficient equipment. Specific rebate amounts vary and are updated periodically. Contact Otter Tail Power Company directly or visit otpco.com/ways-to-save/programs/ for current figures and application forms. Pre-approval before installation is common practice with utility rebate programs, so call before you buy equipment.

Southeastern Electric Cooperative Loan Program

Southeastern Electric Cooperative offers low-interest loans through its partnership with the Rural Electric Economic Development (REED) Fund. Eligible equipment includes geothermal heat pumps, air-to-air heat pumps, electric heat systems, and weatherization upgrades. This is a loan, not a grant, but the below-market interest rate reduces your carrying cost while you wait for tax credits or rebates to arrive. Contact Southeastern Electric Cooperative directly at southeasternelectric.com for current loan terms and application requirements, as rates and terms vary.

South Dakota Renewable Energy System Exemption

South Dakota established a property tax incentive for renewable energy facilities, administered by the S.D. Department of Revenue. Facilities that generate other forms of energy using solar or geothermal resources qualify, provided capacity is under 5 megawatts. For eligible facilities under 5 MW, all real property used or constructed for the facility may qualify for the exemption. This is particularly relevant for geothermal heat pump systems. Consult the S.D. Department of Revenue (dor.sd.gov) to confirm how the exemption applies to residential geothermal installations in your county.

South Dakota Renewable, Recycled and Conserved Energy Objective

South Dakota enacted H.B. 1123 in 2008, establishing a voluntary objective that 10% of all retail electricity sales come from renewable and recycled energy sources. A 2009 modification added "conserved energy" to the eligible categories. This policy, overseen by the South Dakota Public Utilities Commission, is voluntary rather than mandatory, meaning utilities face no penalties for missing the target. While voluntary, this objective encourages retail electricity providers to pursue renewable and conserved energy initiatives.

Eligibility Requirements and How to Apply

Common Requirements Across Programs

Most heat pump incentive programs share these baseline requirements:

• The property must be your primary residence (some utility programs extend to rental properties; confirm with your utility)
• Installation must be performed by a licensed, certified HVAC contractor
• Equipment must meet program-specific efficiency ratings (ENERGY STAR, CEE Tier, or ENERGY STAR Most Efficient depending on the program)
• You must retain the AHRI certificate, installer invoice, and purchase receipt

Income Limits for Federal IRA Rebates

• HEAR (§50123): Household income at or below 150% of Area Median Income. AMI varies by county. Use HUD's AMI lookup tool or ask the South Dakota Public Utilities Commission or relevant state agency once South Dakota's program launches.
• HOMES (§50122): LMI households receive 2x the standard rebate. Standard rebates are available to households above LMI thresholds, subject to the modeled energy savings requirement.

Applying for the Federal Tax Credit (§25C)

1. Purchase and install qualifying equipment with a licensed contractor.
2. Obtain the AHRI certificate from your contractor.
3. Keep the itemized installer invoice showing equipment model and labor costs separately.
4. File IRS Form 5695 with your federal tax return for the year of installation.
5. Consult IRS instructions for Form 5695 for current line entries and any updates.

Applying for Utility Rebates

1. Contact your utility (Otter Tail Power or Southeastern Electric) before purchasing equipment to confirm current rebate amounts and pre-approval requirements.
2. Submit any required pre-approval forms.
3. Complete installation with a licensed contractor.
4. Submit the rebate application with supporting documentation: invoice, AHRI certificate, and proof of purchase.
5. Processing times vary; ask your utility for the current timeline.

Maximizing Your Savings: Stacking Federal and State Programs

What Can Be Combined

The most important rule: §25C stacks with everything. The federal tax credit does not conflict with utility rebates, state property tax exemptions, or either IRA rebate program.

HOMES and HEAR cannot both apply to the same measure. If you claim a HEAR rebate for your heat pump HVAC system, you cannot also claim a HOMES rebate for that same system. You can, however, use HOMES for one improvement (e.g., insulation) and HEAR for the heat pump, as long as they cover different measures.

Stackability Reference Table

Practical Strategy

For a geothermal heat pump installation, a realistic combined approach involves: claiming the §25C credit (up to $2,000) on your federal return, applying for an Otter Tail Power rebate or Southeastern Electric loan, and confirming whether the geothermal system qualifies for the S.D. Renewable Energy System Exemption through the S.D. Department of Revenue. Once HEAR launches in South Dakota, income-qualified households can layer that on top.

For income-qualified households, HEAR's point-of-sale structure is particularly valuable because it reduces your upfront cost before you ever file a tax return. Pair that with §25C and a utility rebate for the deepest discount.

If your income exceeds the HEAR cap (150% AMI), focus on §25C plus utility rebates. The HOMES program may still be available if your project achieves the required energy savings threshold.

What's New in South Dakota Heat Pump Incentives (2024-2025)

The IRA Programs Are the Biggest Change

The Inflation Reduction Act created HOMES (IRA §50122) and HEAR (IRA §50123) as the largest new federal heat pump incentive programs in decades. For South Dakota residents, these represent a potential $8,000 rebate on a heat pump HVAC system that did not exist before 2022. The catch is that both programs require state-level administration, and states have launched at different paces.

South Dakota's Rollout Status

As of the 2024-2025 period, South Dakota's administration of HOMES and HEAR rebates is in development. The U.S. Department of Energy has provided guidance and funding allocations to states, but the actual point-of-sale rebate infrastructure requires state agencies to build out program rules, contractor networks, and application systems. Consult the South Dakota Public Utilities Commission or relevant state agency for the most current launch timeline. Do not delay a needed installation waiting for these programs if the timeline is uncertain; the §25C credit is available now.

State and Utility Program Updates

No significant recent changes to South Dakota-specific legislation affecting heat pump incentives have been identified in current source material. Otter Tail Power Company and Southeastern Electric Cooperative continue their existing programs on an ongoing basis. Rebate amounts and loan terms at the utility level can change annually, so verify current figures directly with each utility before budgeting your project.

Expanding Access

When HOMES and HEAR launch in South Dakota, they will meaningfully expand access for lower-income households. The income-scaling in HOMES and the income cap in HEAR are specifically designed to make heat pump upgrades financially viable for households that cannot absorb large upfront costs even with a tax credit. Combined with Southeastern Electric's low-interest loan program, rural South Dakota households will have multiple tools to reduce both upfront and ongoing costs. Monitor the South Dakota Public Utilities Commission or relevant state agency and the U.S. Department of Energy's IRA program pages for launch announcements.

Federal Tax Considerations

Heat pump rebates in South Dakota can provide significant federal tax benefits under specific sections of the Internal Revenue Code (IRC). Notably, IRC § 25C and § 25D offer credits for energy-efficient heat pumps and geothermal heat pumps, respectively.

• IRC § 25C: Provides a credit of 30% of the cost of qualifying heat pumps and heat pump water heaters, up to a $2,000 annual cap, separate from the $1,200 general home improvement cap.
• IRC § 25D: Offers a 30% uncapped credit for geothermal heat pumps (ground-source), provided the equipment meets the highest efficiency tier set by CEE or qualifies as ENERGY STAR Most Efficient.
• Form 5695: Taxpayers must claim the applicable credits using Form 5695 to report their energy-efficient home improvements.
• Eligibility Requirements: Ensure that the heat pump or geothermal system meets the necessary efficiency standards to qualify for the credits.
• State Conformity: While South Dakota generally aligns with federal tax provisions, it's essential to verify any state-specific implications with a local CPA.
