Nebraska Mileage Deduction 2026: 4.55% Top Rate

Nebraska's top individual income tax rate is 4.55% for 2026. The widely quoted 3.99% is the 2027 rate, not this year's. The step-down is written into statute with explicit dates, so there is no ambiguity about which rate applies to the return you file next spring.

Source: Neb. Rev. Stat. § 77-2715.03, which sets rate four at "4.55% for taxable years beginning or deemed to begin on or after January 1, 2026, and before January 1, 2027" and 3.99% for years beginning on or after January 1, 2027. Verified August 2026.

What the deduction is worth in Nebraska

At 15,000 business miles you deduct $11,138 at 76¢ (the rate from 1 July 2026; 72.5¢ before that). Against the 4.55% top bracket that is roughly $507 in Nebraska tax, plus about $4,154 federally, for around $4,661 total. The federal figure assumes a 22% marginal income tax bracket plus 15.3% self-employment tax and no qualified business income deduction. Your own number moves with your bracket.

Why the 2027 step-down changes the timing

Because the top rate drops from 4.55% to 3.99% on January 1, 2027, a deduction taken in 2026 is worth about 14% more in state tax than the identical deduction taken a year later. For a driver with a lumpy year, that is a real reason to make sure every 2026 mile is captured rather than reconstructed later from memory.

It also raises the cost of a sloppy log. Miles you cannot substantiate are not deferred to a cheaper year, they are simply lost.

Nebraska's own tips deduction

Nebraska adopted a state-level deduction for qualified tips for tax years 2025 through 2028, separate from the federal OBBBA provision. Self-employed individuals may deduct qualified tips received, capped at net self-employment income. Delivery and rideshare drivers who both earn tips and drive heavy business miles stack two deductions here that most states do not offer together.

How to File

Deduct your business miles on federal Schedule C, Line 9 at 76¢ (the rate from 1 July 2026; 72.5¢ before that)/mile. Nebraska begins from federal adjusted gross income, so the deduction carries through automatically. If you expect to owe more than $500 in Nebraska tax, make quarterly estimated payments.
