STAR Act of 2025

The STAR Act of 2025 adds a 25% tax credit for qualified semiconductor design expenses incurred by U.S. companies. It directly affects businesses conducting semiconductor design in the United States, covering both in-house costs (like wages and supplies for U.S. design work) and contracted design services. The credit excludes duplicating existing products, cosmetic design, or activities unrelated to performance or reliability improvements. This incentive expires for design expenses paid after December 31, 2036.
