What Is Form 6765 Used For?
Form 6765 is the official IRS document businesses use to claim the federal R&D tax credit under Internal Revenue Code Section 41.
The credit rewards companies for investing in innovation, whether through new products, improved processes, or software development. Many businesses miss out because they assume R&D only applies to labs or high-tech firms—but that’s a myth.
Who Qualifies for the R&D Tax Credit
The IRS has a four-part test to determine eligibility:
- Permitted Purpose: Activities improve function, performance, quality, or reliability
- Technological in Nature: Must rely on engineering, computer science, or physical sciences
- Elimination of Uncertainty: Results are not known at the start of the project
- Process of Experimentation: Testing alternatives or hypotheses
Companies of nearly any size or industry may qualify if they meet these criteria.
Understanding Qualified Research Expenses (QREs)
QREs form the foundation of the R&D credit. According to IRS guidelines, QREs generally include:
- Employee wages performing or supporting research
- Supplies used in R&D
- Contract research expenses, often limited to 65%
- Certain cloud computing costs tied to development
Non-qualifying expenses include marketing, general overhead, and routine operational costs.
Step-by-Step Instructions for Form 6765
Following IRS Form 6765 instructions carefully ensures you claim the maximum credit.
Section A: Regular Credit
This calculates the credit based on historical gross receipts and base-period research expenses. Best for companies with long operational history.
Section B: Alternative Simplified Credit (ASC)
The ASC method simplifies calculation using a three-year average of prior QREs. Many businesses prefer it for easier record-keeping.
Section C: Elections and Additional Forms
This section includes elections that affect how the credit applies and links Form 6765 to other tax filings.
Section D: Payroll Tax Offset
Startups can use this section to apply the R&D credit against payroll taxes instead of income taxes.

ASC vs Regular Method: How to Calculate

The IRS may not require attachments, but keeping proper documentation is essential:
