The remaining federal net operating losses have an indefinite carryover period but can only offset eighty percent of taxable income in a given year. The state net operating losses expire between 2026 and 2042.

On July 4, 2025, President Trump signed into law the legislation commonly referred to as the One Big Beautiful Bill Act ("OBBBA").
