What is Form 6765 used for?
Form 6765 is used to calculate and claim the federal R&D tax credit allowed under Internal Revenue Code Section 41. Businesses use this form to:
- Claim the research credit for current tax year
- Choose between the regular method or Alternative Simplified Credit
- Elect the reduced credit under Section 280C
- Apply a portion of the credit against payroll taxes if eligible
Simply put, Form 6765 turns innovation costs into tax savings when completed correctly.
Who qualifies for R&D tax credit?
Many businesses qualify without realizing it. You do not need a lab coat or patent pending sign.
A business qualifies for the R&D tax credit if its activities meet the IRS four-part test:
- The activity aims to create or improve a product, process, software, or formula
- The work involves technical uncertainty
- The research relies on principles of engineering, science, or computer science
- The activity includes a process of experimentation
Manufacturers, software developers, engineers, architects, and startups often qualify. Even failed projects can count if they involved experimentation.
What are QREs?
QREs stand for Qualified Research Expenses, and they form the backbone of Form 6765 calculations.
QREs generally include:
- Employee wages for staff performing, supervising, or supporting R&D
- Supplies used during research activities
- Contract research costs paid to third parties, subject to IRS limits
General overhead, marketing costs, and administrative expenses do not qualify. Clear tracking of research costs helps ensure compliance and maximizes credits.
How to calculate ASC vs regular method?
The IRS allows two methods for calculating the R&D credit. Choosing the right one matters.
Regular Credit Method
This method compares current year QREs to a base amount derived from historical data and gross receipts. It often produces higher credits for businesses with long research histories but requires more documentation.
Alternative Simplified Credit (ASC)
ASC uses a simpler formula based on the average QREs from the prior three years. Many small and mid-sized businesses prefer ASC due to lower complexity and reduced recordkeeping burden.
Once elected, ASC generally applies going forward unless revoked. Modeling both methods helps determine which provides the best result.
