    Introduction to IRS Form 6765

    Form 6765 Instructions

    Innovation drives growth, but innovation also costs money. The IRS created Form 6765 to reward businesses that invest in research and development. These Form 6765 Instructions help companies reduce tax liability while staying compliant with federal rules.

    If you design software, improve manufacturing processes, or develop new products, this form may unlock real tax savings. The key lies in accuracy, documentation, and understanding how the credit works.

    What Is Form 6765 Used For?

    Form 6765 allows businesses to claim the Research and Development Tax Credit under Internal Revenue Code Section 41. Companies use it to calculate and report eligible R&D expenses on their federal income tax return.

    The credit reduces income tax dollar for dollar. Qualified startups can also apply part of the credit against payroll taxes.

    Who Qualifies for the R&D Tax Credit?

    Many business owners assume only large tech firms qualify. That belief misses the mark.

    You may qualify if your business:

    • Develops or improves products, software, or processes

    • Solves technical problems through experimentation

    • Relies on engineering, computer science, or hard sciences

    • Faces uncertainty in design or methodology

    Industries that often qualify include software, manufacturing, architecture, construction, biotech, and engineering.

    Business size does not matter. Profitability does not matter. Even companies with losses can benefit.

    Understanding Qualified Research Expenses (QREs)

    What are QREs?

    QREs include costs directly tied to qualified research activities. The IRS defines them clearly.

    Common QRE Categories

    • Wages paid to employees performing R&D

    • Supplies used during experimentation, excluding capital items

    • Contract research costs, typically at 65 percent of total paid

    • Cloud computing costs when used for development and testing

    You must connect each expense to a qualified activity. Strong documentation protects your claim during audits.

    Choosing Between ASC and Regular Credit Method

    One of the most important instructions Form 6765 covers is credit calculation.

    Regular Credit Method

    Regular Credit

    • Uses historical research spending

    • Offers higher credits in some cases

    • Requires detailed records from prior years

    Alternative Simplified Credit (ASC)

    Alternative Simplified Credit

    • Easier to calculate

    • Uses average QREs from the previous three years

    • Often preferred by small and mid sized businesses

    How to calculate ASC vs regular method?

    ASC equals 14 percent of current year QREs above 50 percent of the prior three year average. The regular method uses a complex base amount formula.

    Most companies choose ASC due to simplicity and lower audit risk.
