Nebraska uses a graduated, or progressive, income tax system, meaning your income is taxed in layers, with each portion taxed at the rate assigned to that bracket rather than your entire salary being taxed at a single rate. Nebraska has been gradually lowering its top marginal rate as part of an ongoing, multi-year tax reform effort, with the top rate falling from 5.84% in 2024 down toward the high 4% range, and further reductions scheduled in the years ahead.
Because these thresholds are adjusted periodically and the phase-down continues on a legislated schedule, it's worth confirming the exact current-year brackets directly with the Nebraska Department of Revenue rather than relying on a number that may shift from one tax year to the next.
| Approximate Bracket | Marginal Tax Rate |
|---|
| Lowest bracket | Around 2.46% |
| Second bracket | Around 3.51% |
| Upper-middle bracket | Around 4.4% |
| Top bracket | Continuing to phase down each year |
Because it's a marginal system, someone whose income reaches the top bracket isn't taxed at that top rate across their entire salary, only on the portion of income that falls above the highest threshold. Everything below that point is still taxed at the lower rates first.
