Federal Changes Affecting State Taxes

Federal tax changes also impact state taxes since many states use federal adjusted gross income (AGI) as their starting point. Key federal changes for 2026 include inflation-adjusted brackets and standard deductions. Most states that conform to federal tax law have automatically adopted these changes, while others have decoupled from specific provisions.
