Nebraska Advantage Research and Development Tax Credit

Who qualifies

• Must conduct qualified research activities physically located within Nebraska following federal IRC §41 four-part test
• Qualified research expenses include: wages of Nebraska-based employees performing, supervising, or supporting research; Nebraska supplies consumed in research; 65% of Nebraska contract research payments
• All Nebraska income-tax-filing entities eligible: C-corporations, S-corporations, LLCs, partnerships, sole proprietors
• Credit is incremental — applies only to Nebraska-located QRE above the average of the 3 prior taxable years. New companies with fewer than 3 years of Nebraska QRE history use a proportional startup calculation
• Credit is non-refundable; unused credits carry forward up to 15 years. The credit cannot generate a refund or reduce Nebraska income tax liability below zero
• No minimum revenue, employee count, or project size requirements
• Research must satisfy all four prongs of the §41 test: technological in nature, developing/improving a business component, conducted under uncertainty, and through experimentation

What it covers

How to apply

1. 1

   Calculate Nebraska-located QRE for current and prior 3 years

   Determine your Nebraska-located QRE for the current taxable year and the 3 preceding years using federal IRC §41 expense categories. For companies with fewer than 3 years of Nebraska QRE history, Nebraska uses a startup base calculation similar to the federal startup rules — the prior-year average is computed proportionally.

   ~6 hrs

2. 2

   Compute the incremental base and excess QRE

   Average the Nebraska-located QRE from the 3 prior years to establish your base. Subtract this average from your current-year Nebraska QRE. The positive difference is the incremental QRE on which the 15% credit applies. If current-year QRE does not exceed the 3-year average, no credit is earned for that year.

   ~2 hrs

3. 3

   Apply the 15% credit rate

   Multiply the incremental QRE (current year minus 3-year average) by 15% to compute the credit for the current year.

   ~1 hrs

4. 4

   Complete Nebraska Schedule III-B

   File Schedule III-B (Research and Development Tax Credit) with your Nebraska income tax return. The schedule walks through the base calculation, incremental QRE, current-year credit, and any carryforward from prior years. Attach to Form 1120N (C-corps), Form 1120-SN (S-corps), Form 1040N (individuals), or applicable partnership return.

   ~3 hrs

5. 5

   Apply credit and manage carryforward

   The credit offsets Nebraska income tax liability. Unused amounts carry forward up to 15 years — maintain a vintage-year carryforward schedule. Apply oldest-vintage credits first to maximize the 15-year utilization window.

   ~2 hrs

6. 6

   Retain supporting documentation

   Keep Nebraska-specific QRE documentation: employee timesheets by project with Nebraska location, supply invoices, contractor agreements. Retain at least 3 years from the return due date. Nebraska DOR audits of R&D credits align with federal §41 documentation standards plus Nebraska-location evidence.

   ~3 hrs

Deadline & timing

The 15-year carryforward period is generous and allows credits to accumulate for growing companies.
