Do you believe federal tax incentives are an effective way to accelerate large domestic industrial projects?

Semiconductor developers are accelerating construction schedules to meet the December 2026 deadline for the 35 percent advanced-manufacturing tax credit established by the CHIPS and Science Act. Projects must demonstrate physical on-site progress to qualify for the incentive.

Why it matters

Firms are rushing to finalize site development and infrastructure as statutory deadlines approach. The ability to lock in these federal credits will determine the long-term economic viability of large-scale manufacturing investments across the United States.

To qualify for the 35 percent tax credit, developers must show tangible progress like concrete foundation work or utilize a 5 percent Safe Harbor pre-payment threshold. Projects meeting these rules secure a 10-year continuity window that extends to 2036.

The players

AVAIO Digital Partners

An infrastructure investment firm specializing in digital assets and large-scale industrial projects.

The details

Treasury guidance requires developers to prove active site development to secure the benefit, with Project Hercules in Appomattox County, Virginia, serving as a model for this $3 billion investment approach. AVAIO Digital Partners has secured a 400-acre industrial park for the site. Treasury rules allow for split-ownership models of shared infrastructure, enabling developers to pool resources to satisfy the continuity requirements necessary for long-term tax stability.

December 2026 marks the final deadline for initial tax credit eligibility.
The 10-year continuity safe harbor for qualified projects extends through 2036.

The Tech Race

The push to initiate site work reflects a critical phase in the implementation of the CHIPS and Science Act. Developers are navigating the difference between paper-based project planning and the tangible construction milestones required to secure federal manufacturing incentives.

This timeline impacts the pace of regional industrial development and local construction hiring in areas like Appomattox County. The shift in activity is driven by the need to satisfy federal Treasury rules for large-scale capital investments.

The takeaway

The race to secure tax credits is forcing a shift in how infrastructure projects are financed and built. Readers should monitor upcoming corporate project filings to see which developers successfully meet the 2026 physical progress benchmarks.
