Energy Tax Incentives in 2026: Key Deadlines and Filing Traps CPAs Must Avoid

February 23, 2026 – 1 PM EST

Energy tax incentives are appearing in more client filings than ever. In 2026, the biggest risks for CPAs are no longer eligibility questions, but missed deadlines, timing errors, and unsupported assumptions made under filing pressure. This webinar will be led by David Diaz, Chief Strategy Officer at Walker Blue, and John Robinson, Executive Director, Residential Energy Programs. The session is designed specifically for CPA firms advising developers, owners, and investors with exposure to energy tax incentive–eligible projects.
