Path-Q Solar

What records should I keep to support a future audit of a solar tax credit claim?

Answer

Keep records that establish the eligible costs, ownership, property use, installation or placed-in-service date, payment, and system scope. Retain the governing tax guidance and professional advice used, along with contracts, invoices, permits, approvals, financing records, and completion evidence for the applicable record-retention period.

Key points

  • Keep itemized invoices separating eligible equipment and installation from noneligible or unrelated work.
  • Retain purchase, financing, ownership, lease, and incentive documents showing who paid for and owns the system.
  • Preserve permits, inspection approvals, commissioning or permission-to-operate records, photographs, and payment evidence.

What it depends on

  • Current tax rules and record-retention requirements
  • Ownership and financing structure
  • Property use and installation date
  • Eligible cost categories

Risks and trade-offs

  • Incomplete records can make it difficult to substantiate a claim even if the project was otherwise eligible.
  • A contractor's summary invoice may not document the required cost allocation.
  • Records should be protected from loss and kept accessible after the contractor or lender relationship ends.

Information you may need

  • Current official tax guidance
  • Complete contracts, invoices, and payment records
  • Permit, inspection, and commissioning records
  • Tax return workpapers and professional advice
