The short answer
The 30% federal Residential Clean Energy Credit applies in all 50 states through 2032. Top stacking states for 2026: NY (NY-Sun rebate $0.20-$0.50/W), MA (SMART solar incentive), NJ (TRECs $90-$160/MWh), MD ($1,000 residential grant), IL (Illinois Shines block grant), CA (SGIP storage rebate, NEM 3.0 export rates).
Federal solar incentives are uniform — the 30% Residential Clean Energy Credit applies in all 50 states through 2032. State and local incentives vary wildly. NY, MA, NJ, MD, IL, CA, OR, and WA stack the most rebates and tax credits. TX, FL, and the Mountain West rely mostly on the federal credit alone but offset that with abundant sun and falling install prices. This guide tracks 2026 state incentives and how they stack with the federal credit.
Federal baseline
30% Residential Clean Energy Credit (IRC 25D): panels, inverters, batteries, labor, permits. No cap. Phases down 26% in 2033, 22% in 2034, expires 2035 unless extended.
Modified Accelerated Cost Recovery System (MACRS): commercial-only, 5-year accelerated depreciation. Does not apply to residential.
Investment Tax Credit (ITC) for commercial solar: 30% with bonus adders (10-20% additional for low-income community / energy community / domestic content). Up to 70% total federal incentive on commercial installs.
Top state stacks (2026)
New York: NY-Sun upfront rebate $0.20-$0.50/W (region-dependent). 25% state income tax credit up to $5,000. Property tax exemption. Net metering at full retail rate. Stacked with federal: 50-60% off install.
Massachusetts: SMART (Solar Massachusetts Renewable Target) pays $0.05-$0.30/kWh produced for 10 years. State income tax credit 15% up to $1,000. Property tax exemption. Net metering at retail rate.
New Jersey: SREC-II / Successor program produces TRECs (transition renewable energy certificates) worth $90-$160/MWh for 15 years. Sales tax exemption. Property tax exemption.
Maryland: residential clean energy grant $1,000 per system. State residential storage tax credit 30% up to $5,000. Property tax exemption. Net metering retail.
Illinois: Illinois Shines block grant pays installer ~$0.07-$0.10/kWh for 15 years (passed to homeowner as upfront discount or credit). Property tax exemption.
California: NEM 3.0 (export rate ~$0.05/kWh) + SGIP battery rebate ($150-$1,000/kWh in high-fire-risk zones). Property tax exemption.
How to find every incentive that applies to your address
The DSIRE database (dsireusa.org) at the NC Clean Energy Technology Center tracks every federal, state, local, and utility incentive in the United States. It is free, comprehensive, and updated monthly. Search by ZIP code for a personalized list of programs that apply to your specific address. DSIRE is the single most authoritative source for solar incentives — most installers reference it during quoting.
EnergySage state pages summarize the practical view: typical install prices, all major incentives, net metering rules, and a rolling marketplace of installer quotes. The pages are written for homeowners rather than energy policy professionals, which makes them easier to digest than the raw DSIRE data.
Local utility programs add a third layer that DSIRE captures but homeowners often miss. Many investor-owned utilities (PG&E, SDG&E, ConEd, Eversource, National Grid, ComEd, BGE, PSE&G) offer their own rebates on heat pumps, batteries, EV chargers, and demand-response enrollment that stack on top of state and federal programs. Always check your specific utility website during the quote process.
The IRA (Inflation Reduction Act) also unlocked income-qualified rebates beyond the standard tax credit. Households below 80 percent of area median income (AMI) can access HEEHRA rebates of up to $14,000 covering heat pumps, electrical upgrades, insulation, and induction stoves — several of which pair well with a solar install. The rules vary by state implementation; check your state energy office for the current status.

Incentive stacking — federal credit + state programs + utility rebates
What is expiring or changing in 2026 and 2027
The 30 percent federal Residential Clean Energy Credit (Section 25D) is locked at 30 percent through 2032. It steps down to 26 percent in 2033, 22 percent in 2034, and expires after 2034 unless extended by Congress. The window of full-rate access is the next six years, which is unusually generous compared to most federal energy incentives.
NY-Sun rebates are tracked by region and step down as megawatt-block targets are met. Long Island and Con Edison territories have already stepped down materially in 2025 and 2026. Upstate New York rebates remain at higher tiers. Check the current block status before assuming a quoted rebate.
New Jersey transitioned from SREC to TREC (transition certificates) and is now in the SuREC successor program. The program is scheduled to continue through at least 2030 with declining production-incentive values per megawatt-hour. Homeowners installing in 2026 lock in a 15-year SuREC stream at the year-of-install rate.
California NEM 3.0 reduced export credits dramatically in April 2023 and remains in effect. The shift made battery storage much more economically attractive in California (because self-consumption now beats export) and reshaped the typical California system from solar-only to solar plus storage.
Recap
Bottom line
State and local solar incentives in 2026 still represent significant additional value on top of the locked-in 30 percent federal credit, but the active programs change frequently and vary widely by state, utility, and even ZIP code. The right approach is not to read national average articles — it is to pull DSIRE and your specific utility website for your address before signing any quote, then verify with the installer that every applicable program is reflected in the bid.
Combine this guide with the solar-panel-cost-by-system-size cost benchmarks and the solar-financing-loan-vs-lease-cash tradeoff comparison to lock in a quote that captures the full value of the 2026 incentive stack. Net costs after stacking the federal credit, state programs, and utility rebates can drop 40 to 55 percent off gross in active markets — the difference between a 12-year payback and a 6-year payback.
