What is Form 6765 Used For?

Form 6765 is the IRS form businesses use to claim the Research & Development (R&D) tax credit. It helps reduce federal tax liability by reporting qualified research expenses (QREs) incurred during the year.

Businesses can use Form 6765 Instructions to offset regular income taxes or payroll taxes, depending on eligibility. Using the form correctly ensures you claim all eligible credits while staying compliant with IRS rules.

Who Qualifies for R&D Tax Credit?

Not every business is eligible. Generally, to claim R&D credits you must:

  • Conduct activities aimed at improving or developing products, processes, or software

  • Incur qualified research expenses (QREs), including wages, supplies, and contract research costs

  • Operate within the United States or have U.S.-based research

Small businesses and startups can also qualify, even if they have limited taxable income. Many startups leverage the payroll offset option to apply credits against payroll taxes.

Fun Fact: About 60% of small businesses underestimate their R&D credits. You can see more in our Financial Literacy Statistics.

Understanding QREs (Qualified Research Expenses)

QREs are the core of R&D credit calculation. These include:

  • Employee wages for research activities

  • Supplies used in experimentation

  • Contract research costs

  • Rental or lease costs for computers used in R&D

QREs must be directly linked to qualified research. Guessing or inflating numbers can trigger IRS audits, so it’s best to follow IRS instructions closely.

How to Calculate ASC vs Regular Method

When calculating R&D credits, the IRS allows two methods:

  1. Regular Credit Method: Uses a percentage of QREs above a base amount from prior years.

  2. Alternative Simplified Credit (ASC) Method: Often easier for startups or businesses without historical records, calculating a flat 14% of QREs above 50% of average QREs from the past three years.

Choosing the right method depends on historical records, QRE trends, and your tax strategy.

Filling out Form 6765 requires attention to detail. Follow these steps:

  1. Part I – Regular Credit:
