Provide an income tax adjustment for unrealized capital gains

LB 51 proposes to amend Nebraska state tax laws to include a specific adjustment for unrealized capital gains within the state's income tax calculation. The bill aims to align state tax treatment with federal rules regarding gains on assets that have increased in value but have not yet been sold. It would directly affect individual and corporate taxpayers by modifying how their federal adjusted gross income is used to determine state tax liability. Although the legislation includes detailed provisions for various types of income and deductions, it was indefinitely postponed in August 2024 and did not become law.
