What Is Form 6765 Used For?
Form 6765 is used to claim the federal R&D tax credit under IRC Section 41. Businesses file it to reduce tax liability based on eligible research activities.
This form incentivizes innovation. If your company improves products, processes, software, or technology, it likely qualifies. Many businesses skip this credit, assuming it only applies to labs or scientists—but that’s a misconception.
Who Qualifies for the R&D Tax Credit
The R&D tax credit isn’t limited to large tech companies. The IRS outlines a four-part test for eligibility:
-
Permitted Purpose: Activities must improve function, performance, reliability, or quality.
-
Technological in Nature: Must rely on engineering, computer science, or physical sciences.
-
Elimination of Uncertainty: Outcomes were not known in advance.
-
Process of Experimentation: Testing of alternatives or hypotheses is required.
Businesses of any size, in almost any industry, may qualify.
Understanding Qualified Research Expenses (QREs)
QREs are the backbone of the credit. The IRS defines them clearly, and accuracy here is critical. Typical QREs include:
-
Employee wages related to R&D
-
Supplies used in research
-
Contract research expenses (usually 65% deductible)
-
Certain cloud computing costs tied to development
Non-qualifying items include marketing costs, routine testing, and general administrative expenses.
Instructions for Form 6765: Step by Step
Following IRS Form 6765 instructions becomes straightforward when broken down:
Section A: Regular Credit
Calculates the credit using historical gross receipts and base period research expenses. Best for companies with long operating history.
Section B: Alternative Simplified Credit (ASC)
Most businesses prefer ASC. It calculates the credit based on average QREs from the prior three years, requiring fewer historical records.
Section C: Elections and Additional Forms
Links Form 6765 to other tax forms and includes elections that affect how the credit applies.
Section D: Payroll Tax Offset
Allows qualified startups to offset payroll taxes instead of income taxes.

-
Regular Method: Credit equals 20% of current QREs above a base period amount.
