SB 1231 - Federal law requires taxpayers to amortize the deduction for research and experimental expenses over a period of years. This act allows a taxpayer to deduct the full amount of such expenses for the taxpayer's state income taxes during the tax year in which they were incurred.

This act is identical to SB 349 (2025), HB 136 (2025), SB 1365 (2024), and HB 2457 (2024), and to a provision in HCS/HB 1427 (2024).
