What Is IRS Form 6765?
IRS Form 6765 is used by businesses to claim the federal Research and Development (R&D) tax credit. By carefully following the IRS Form 6765 Instructions, companies can accurately report qualified research expenses, calculate the allowable credits, and strategically apply them to reduce federal taxes, ensuring they do not miss out on benefits for innovation, product development, or process improvements.
What Is Form 6765 Used For?
Form 6765 instructions help companies determine eligible R&D activities and calculate the proper credit. The credit can reduce income taxes or payroll taxes for startups. Essentially, it’s a financial reward for innovation.
Use this credit to fund new projects, hire more staff, or reinvest in technology. Businesses often overlook it due to complexity, but following IRS instructions line by line prevents mistakes.
Who Qualifies for the R&D Tax Credit?
Eligible businesses include those developing new or improved:
Products
Processes
Software
Prototypes
Key points:
Businesses of any size can claim the credit.
Startups may use the payroll offset option.
Expenses must be incurred within the United States.
Not every expense qualifies. You must document activities, costs, and outcomes.
Understanding Qualified Research Expenses (QREs)
QREs are central to Form 6765 instructions. They include:
Wages for employees directly involved in R&D
Supplies used for experimentation
Contract research costs
Rental or lease costs for equipment used in research
Internal teams often confuse general operational costs with QREs. Remember: only costs directly tied to R&D activities qualify.
Structure of Form 6765
Form 6765 has multiple sections:
Part A: Regular Credit
Part B: Alternative Simplified Credit (ASC)
Part C: Payroll Tax Offset for startups
Part D: Summary of credit and carryforward
Understanding the structure is crucial to maximize your credit and avoid IRS errors.
Regular Credit vs ASC Method
Businesses can choose between:
Regular Credit Method: Uses actual QREs from the previous four years. Best for companies with detailed historical R&D expenses.
Alternative Simplified Credit (ASC): Uses a flat percentage (usually 14% of QREs exceeding 50% of average prior expenses). Simpler, but sometimes lower than regular credit.
To calculate ASC vs regular method, review historical payroll and research spending. Correct selection can increase your refund substantially.
Step-by-Step Instructions for Form 6765
Instructions Form 6765 2025/2026 are similar, with minor updates for inflation and method adjustments.
Enter basic business information.
Select your credit method (Regular or ASC).

Payroll records showing employee time on R&D
Supply invoices
Contracts with research providers
Project descriptions and technical reports
Financial statements for past four years
Without proper documentation, your claim may be denied.
Quick Note: A complete IRS form list helps businesses and individuals identify the right tax forms for filing, reporting, and claiming credits accurately.
Payroll Tax Offset for Startups
Startups can use the R&D credit to offset payroll taxes, reducing FICA liability up to $250,000 per year.
Eligibility:
Business must have gross receipts of less than $5 million
Must not have been in operation for more than 5 years
This option allows early-stage companies to invest more in growth instead of paying federal taxes.
What Changed in 2025?
Expanded eligibility for small businesses
ASC percentage adjusted slightly due to inflation
Additional guidance on startup payroll tax offsets
Enhanced documentation requirements for QREs
These changes are critical for 2026 filings. Ensure your Form 6765 instructions reflect these updates.
Common Mistakes to Avoid
Misclassifying non-R&D expenses
Forgetting payroll offset eligibility for startups
Using outdated ASC percentages
Missing carryforward credits from previous years
Avoiding mistakes ensures faster processing and prevents IRS penalties.
