Form 6765 Instructions explain how eligible businesses claim the R&D tax credit, outline new 2024–2025 reporting rules, and show required documentation and elections.
Form 6765, Credit for Increasing Research Activities, is the IRS Form 6765 Instructions used to compute and claim the federal research and development tax credit. The credit can lower a company’s federal tax liability dollar for dollar and, for certain startups, offset payroll taxes. The IRS provides updated instructions that explain who qualifies, calculation methods, and elections.
Who can claim the R&D credit
Generally, businesses that perform qualified research activities and incur qualified research expenses may claim the credit. This includes wages for employees who do research, supplies used in research, and certain contract research costs. Startups and small businesses should note the payroll tax election for qualifying small employers. See IRS guidance for details and eligibility criteria.
Key 2024–2025 changes to Form 6765
The IRS revised Form 6765 for tax years starting in 2024. Several important changes affect how you report the credit:
- The form now asks for more detailed business-component level reporting by name and activity type.
- Section G reporting requirements were introduced but the IRS has made Section G optional for tax year 2025 while seeking stakeholder feedback.
- The Instructions include clarifications on what counts as qualified research expenses and group reporting methods.
Those changes mean you must collect more granular data and be ready to explain the technical nature of the R&D work claimed. Tax advisors and developers often recommend preparing both quantitative worksheets and short qualitative summaries for each business component.
Step-by-step: filling out Form 6765
Below is a practical walkthrough of the form’s main sections. Always attach the form to your federal return and keep supporting records.
Section A or B – Choose your computation method
- Section A: Use the regular credit (traditional) method if it gives the best result.
- Section B: Use the alternative simplified credit (ASC). Many taxpayers pick ASC for simplicity, especially smaller firms. The Instructions tell you how to elect ASC or revert to the regular method.
Section C – Credit computation and limit rules
- Compute the credit based on qualified research expenses. Include wages and qualifying supply costs. If you elect the payroll tax offset, follow the detailed limits in the Instructions.
Section D – Payroll tax credit election (if eligible)
- Certain qualified small businesses may elect to apply part of their credit against the employer portion of Social Security tax. This election requires additional worksheets and timely filing.
Section E and F – Other information and QRE summary
- Provide requested narrative or quantitative details about research activities and a summary of Qualified Research Expenses (QREs). The revised Instructions provide templates and clarifications on how to report group activities.
Section G – Business-component reporting
- For tax year 2025 this section may be optional, but the final expectation is more extensive business-component level detail. Prepare names, descriptions, and expense allocations for each component. Even if optional, collecting these details now reduces audit risk later.

Documentation and attachments you must keep
Documentation matters more now than ever. Keep digital copies of:
- Project descriptions and objectives
- Time logs and payroll records showing employee involvement
- Contracts and Form 1099 records for outside contractors paid for research work (reportable via Form 1099-NEC when required)
- Worksheets supporting ASC or regular method calculations
- Sampling plans or statistical methods if you use sampling to estimate expenses
Maintain documentation for at least three years from the date you file, and longer if you amended returns or claimed carrybacks. The IRS has been explicit that valid claims must be supported by adequate documentation.
Common mistakes and how to avoid them
- Overly broad project descriptions. Be specific: explain technical uncertainty, experimental approach, and how you tested alternatives.
- Missing contractor reporting. If you paid independent contractors for R&D, you may need Form 1099-NEC. Track payments and contracts carefully.
- Mixing routine costs with QREs. Administrative or marketing costs do not qualify. Use the Instructions and authoritative guidance to classify expenses.
Practical checklist before filing
- Confirm eligibility for the credit and choose ASC or regular method.
- Prepare QRE summary worksheet for each business component.
- Draft short technical summaries for each claimed project.
- Verify payroll tax election eligibility and compute limits.
- Attach Form 6765 to your federal return and save all supporting records.
If this looks like a lot, that is because it is. Many businesses work with a CPA or a specialist firm like BooksMerge to reduce risk and maximize the legitimate credit.
