Solar Incentives and Tax Credits: A Complete Guide
As of 2026 there is no federal solar tax credit; the 30 percent credit ended for installations completed after 31 December 2025. State rebates, SRECs, property and sales tax exemptions, and net metering are what remain. DSIRE (dsireusa.org) lists them by state.
What Solar Incentives Are Available?
As of 2026 there is no federal tax credit for residential solar; the incentives that remain are state, local and utility programs. The 30 percent Residential Clean Energy Credit was terminated for installations completed after 31 December 2025, so state rebates ($500 to $5,000), SRECs ($50 to $250 each in participating states), property tax exemptions, sales tax exemptions and net metering are now the whole picture rather than additions on top of a federal credit. Here is the incentive landscape for a solar installation.
The Federal Credit Has Ended
There is no federal tax credit for residential solar installed in 2026. The 30 percent Residential Clean Energy Credit (IRC Section 25D) was terminated by P.L. 119-21, Section 70506, enacted 4 July 2025, and is not allowed for expenditures made after 31 December 2025. This is a termination, not a step-down: the Inflation Reduction Act schedule that held the credit at 30 percent through 2032 and reduced it to 26 percent in 2033 and 22 percent in 2034 was repealed, so there is no lower 2026 rate to claim. Timing does not rescue it either — Section 25D(e)(8)(A) treats an expenditure as made when the original installation is completed, so a system contracted and paid for in 2025 but finished in 2026 does not qualify. One thing does survive into 2026: a homeowner who completed a qualifying installation in 2025 and could not use the full credit against 2025 tax may carry the unused portion forward onto a 2026 return. That is a carryforward of a credit already earned, not a credit for new work. The current federal rule is stated on the IRS Residential Clean Energy Credit page, and a tax professional can tell you how any of this applies to your return. (For more on this, see Solar Energy Storage: Batteries and Backup Power.) The Department of Energy’s Homeowner’s Guide to Going Solar walks through site suitability, financing options, and what to ask an installer.
State and Utility Incentives
Many states offer additional incentives: rebates (a direct payment at installation, ranging from $500 to $5,000 in participating states). Solar Renewable Energy Credits (SRECs): certificates representing one megawatt-hour of solar generation that can be sold on SREC markets in states with Renewable Portfolio Standards (Massachusetts, New Jersey, Maryland, Illinois, and others pay $50 to $250 per SREC). Property tax exemptions: most states exempt the added home value from solar from property tax assessment. Sales tax exemptions: some states exempt solar equipment purchases from state sales tax (5 to 10 percent savings on equipment cost). Net metering: the most broadly impactful ongoing incentive (retail-rate credit for excess generation). (For more on this, see Solar Energy and the Environment: What Homeowners Should Know.)
Finding Your State’s Incentives
DSIRE (Database of State Incentives for Renewables and Efficiency, dsireusa.org): the comprehensive database of all state, utility, and federal solar incentives. Enter your zip code to see all applicable incentives. Your solar installer should provide a complete incentive summary as part of the proposal — if they do not address state incentives, ask specifically about each one listed on DSIRE for your state. (For more on this, see How to Find a Reputable Solar Installer.)
Working With a Contractor on This Project
Getting the right outcome on any home services project starts before the work begins. A few consistent practices make the difference between a smooth project and a frustrating one.
Get at least two or three quotes. A single quote gives you no basis for comparison. Two or three quotes reveal the market rate for the work, expose scope differences between bidders, and let you assess contractor communication quality before any commitment is made. The lowest bid is not automatically the best value if the scope is thin or the materials are underspecified.
Ask for licenses and insurance before work starts. Verify current general liability insurance and, for any work involving workers on your property, workers compensation coverage. Licensing requirements vary by state and trade; confirm the specific requirements in your jurisdiction. A licensed contractor who carries appropriate insurance protects both parties if something goes wrong during the project.
Get the scope in writing. A written proposal that specifies materials, labor scope, timeline, what is included (permits, cleanup, disposal), and warranty terms is the foundation of a professional engagement. Verbal agreements on any of these points invite misunderstanding. For any project over $500, written scope is non-negotiable.
Clarify the payment schedule upfront. A reasonable payment schedule ties major payments to project milestones: a deposit at signing, a payment at material delivery or project start, and a final payment at completion after a walkthrough confirms satisfaction. A contractor who requires full payment upfront before work begins is a red flag in any trade.
Making a Confident Decision
The information in this article is designed to help you ask better questions of the professionals you work with, evaluate their answers with more confidence, and understand the decisions involved in this type of home services project. It is not a substitute for professional assessment of your specific home.
Every home is different. Roof slopes, local weather, tree exposure, soil conditions, and existing system condition all affect what the right solution is for your specific situation. The general principles here apply broadly, but a professional who assesses your home in person will give you guidance that accounts for the details that general articles cannot.
When you are ready to move forward, getting at least two or three quotes from licensed, insured, local contractors is the most important practical step. It lets you compare approaches, assess contractor quality, and confirm that the solution proposed matches your specific situation and budget.
Solar Installation Cost at a Glance
Here is a quick reference for residential solar installation costs. As of 2026 there is no federal tax credit for residential solar, so these figures are what homeowners actually pay before any state, local, or utility incentive.
| Cost Factor | Typical Range | Notes |
|---|---|---|
| Typical home system (8 to 12 kW) | $21,000 to $31,000 installed | No federal tax credit applies to a system installed in 2026. Any reduction comes from state, local, or utility programs. |
| Small system (3 to 7 kW) | $9,000 to $18,000 installed | Same: the quoted price is what you pay, before any local incentive. |
| Large system (13 to 15 kW) | $34,000 to $40,000 installed | Same: the quoted price is what you pay, before any local incentive. |
| Battery storage add-on (e.g., Tesla Powerwall, Enphase IQ) | $8,000 to $15,000 per battery unit | Storage was covered by the same federal credit and carries no federal credit for a 2026 installation either. |
| Per-watt cost | $2.50 to $3.50 per watt | for most residential installations (before incentives) |

Payback period: commonly quoted at 6 to 12 years, but those figures assumed a 30 percent federal credit that no longer applies to 2026 installations. Without it, payback runs correspondingly longer — ask your installer for an estimate built on the full price you are actually paying. Electricity rates still matter most: high-rate states (California, Hawaii, Massachusetts) pay back faster than low-rate states.
As of 2026 there is no federal tax credit for residential solar. The 30 percent Residential Clean Energy Credit (IRC Section 25D) was terminated by P.L. 119-21 and does not apply to expenditures made after 31 December 2025 — and because the law treats the expenditure as made when installation is completed, a system paid for in 2025 but finished in 2026 does not qualify. State, local, and utility incentives are unaffected and are now the only rebates in play; check DSIRE (dsireusa.org) for your state, and the IRS Residential Clean Energy Credit page for the federal rule. A homeowner who completed an installation in 2025 may still carry an unused portion of that credit forward onto a 2026 return; a tax professional can say how it applies to you.
Frequently Asked Questions
There is no longer one for new work. The Residential Clean Energy Credit (IRC Section 25D), worth 30 percent of installed cost, was terminated by P.L. 119-21 and is not allowed for expenditures made after 31 December 2025. Because the law treats the expenditure as made when the installation is completed, a system paid for in 2025 but finished in 2026 does not qualify. A homeowner who completed a qualifying installation in 2025 and could not use the whole credit against 2025 tax may carry the unused portion forward onto a 2026 return. Confirm your own position with a tax professional.
Massachusetts: state income tax credit of 15 percent (capped at $1,000), a strong SREC market ($50 to $250/SREC), property tax exemption, sales tax exemption. There is no federal credit stacking on top of any of these as of 2026. New Jersey: strong SREC market, property tax exemption. Maryland: strong SREC market, property tax exemption. California: NEM 3.0 net metering (reduced from prior policy), property tax exemption. New York: 25 percent state tax credit (capped at $5,000), property tax exemption.
Solar Renewable Energy Credits (SRECs): certificates that represent one megawatt-hour (1,000 kWh) of solar electricity generation. In states with Renewable Portfolio Standards (RPS) that include a solar carve-out: utilities must purchase a certain percentage of their electricity from solar. They do this by buying SRECs from solar owners. SREC markets exist in Massachusetts, New Jersey, Maryland, Illinois, Pennsylvania, Ohio, Washington DC, and others. Current SREC prices: $50 to $250 per SREC depending on the market. A 6 kW system might generate 6 to 8 SRECs per year.
Federal credit: no longer available for 2026 installations, so there is nothing to report; a 2025 credit carried forward is a credit against tax, not income. State rebates: generally not taxable at the federal level (the IRS has ruled that utility rebates for solar reduce the tax basis of the system but are not taxable income). SREC income: generally taxable as ordinary income in the year received. Consult a tax professional for your specific situation.
Net metering: a billing arrangement where excess solar electricity exported to the grid is credited to your account at the retail electricity rate (or a specified rate). As of 2026: most states have net metering policies, though the specific rates and structures vary widely. California's NEM 3.0 (effective 2023) reduced export credits significantly for new solar customers. DSIRE (dsireusa.org) lists each state's net metering policy. Confirm your utility's specific net metering tariff before purchasing solar -- it affects the financial model significantly.
