Frequently Asked Questions
What Is Form 6765 Used For?
Form 6765 is used to calculate and claim the federal Research and Development Tax Credit. Businesses attach it to their income tax return to reduce tax liability or payroll taxes.
The IRS designed this form under Internal Revenue Code Section 41. The goal is simple. Encourage innovation inside the United States.
If your business improves products, software, manufacturing methods, or internal systems, Form 6765 may apply to you.
What Is the R&D Tax Credit?
The R&D Tax Credit rewards businesses that invest time and money into innovation. According to the IRS, qualified activities must involve technical uncertainty and a process of experimentation.
This credit applies across industries. Software, manufacturing, engineering, biotech, and even food development often qualify.
The credit reduces income tax or payroll tax, depending on eligibility. That makes it one of the most valuable credits available to growing businesses.
Who Files Form 6765?
Any business claiming the R&D Tax Credit files Form 6765. This includes:
C corporations
S corporations
Partnerships
Sole proprietors
Qualified startups
Who files Form 6765 depends on who incurs the research expenses. The entity paying wages and costs claims the credit.

You may qualify if your activities aim to:
Develop or improve a product or process

Use engineering, computer science, or physical sciences
Follow a trial and error approach
The IRS focuses on activity, not company size. Startups and small businesses qualify as often as large corporations.
Understanding Qualified Research Expenses

Qualified Research Expenses form the foundation of Form 6765 calculations.

Section 280C Reduced Credit Election
