Federal Solar Tax Credit in 2026

Current IRS guidance for residential property placed in service after 2025.

Reviewed July 2026

Current IRS guidance states that the Residential Clean Energy Credit is not available for property placed in service after December 31, 2025.

Watch for outdated proposals

A calculator or proposal that automatically subtracts 30% from a 2026 residential project may be using old assumptions.

What to verify

  • Whether the proposal assumes a federal homeowner credit.
  • Whether the payment schedule assumes a large voluntary loan payment.
  • Whether any incentive is guaranteed, conditional or merely estimated.
  • Whether the system’s placed-in-service timing is clearly documented.

Tax outcomes depend on individual circumstances. Use current IRS instructions and a qualified tax professional.
