Form 6765 (Including Section G)
Form 6765 is the main federal form for claiming the credit for increasing research activities. This page explains what it is for, who files it and how the agent supports the work, with a link to the official source.
What the form is
Form 6765 calculates the credit. It brings together the qualified research expenses a business has incurred and works out the credit using one of the methods the rules allow. It also includes Section G, which asks for detail about the business components behind the claim. In plain terms, the form asks the business to say what it researched, who did the work and what it cost, and then does the arithmetic.
For many businesses the form is short compared with the work behind it. The hard part is not filling the boxes. It is having records that support each number, so that a reviewer can sign the form with confidence and an examiner, if one ever asks, can follow the trail.
Who files it
Businesses that claim the federal research credit, usually with their income tax return. A business that is a qualified small business may also use the credit against payroll tax through a separate election, which has its own form. Whether a particular business can claim the credit, and by which method, is for its CPA or enrolled agent to decide.
What the agent prepares
A draft of the form, with the figures tied to the costs and business components captured during the year, so your reviewer can check each line. The agent fills in what it can from the records, and marks lines where the records are thin or where a decision is needed. Each figure links back to the underlying cost record and evidence.
Key points
Confirm current requirements with a professional.
- Section G business-component detail is required from tax year 2026, with exceptions for small filers.
- Records that tie each business component to its costs make Section G much easier to complete.
- Different calculation methods are available. Your CPA or enrolled agent chooses.
- The credit is reported on the form but is also affected by other rules, so the reviewer checks how it fits with the rest of the return.
How a reviewer works through the form
- 1
Check the projects
Confirm that each business component listed is supported by evidence and that the description says what was uncertain and how it was tested.
- 2
Check the costs
Trace wages, contractor payments and supplies back to the records and to the time allocation.
- 3
Check the method
Decide which calculation method is appropriate, and confirm the figures follow from it.
- 4
Check the detail
Review Section G for completeness and consistency with the rest of the claim, and ask for missing information.
A worked example (illustrative)
The figures here are invented, and no credit rate is applied. A company has three research projects. For each, the agent has gathered a description, a list of the people involved, their time shares and the related costs. When the reviewer opens the draft of the form, each project appears as a business component with its description and costs. One project has no description beyond a ticket title, and the agent has marked it. The reviewer asks the technical lead for two sentences on the technical uncertainty and the experiments tried. Once the lead writes them, the component is complete, and the reviewer can move on to the next. The form is not final until every component supports itself.
Limits
The agent drafts the form but does not decide eligibility or choose the method for you. Rules and form requirements change, including the requirements for the detail on business components, so please check the official source and speak to your CPA or enrolled agent. Nothing here is tax advice, and nothing guarantees that a claim will be accepted. Forms are filed through an authorized IRS e-file provider or tax software, not by Cost Guru.
Tax rules change. Confirm anything here with a licensed CPA or enrolled agent before relying on it.
Records that make the form easier to complete
- A short description of each business component, written by someone who worked on it.
- Dated notes on what was uncertain and what was tried.
- Time records or reasoned splits for each person on each project.
- Payroll records tied to those people.
- Invoices for supplies and contractor work, labeled by project.
- Notes on any changes of method or scope during the year.
Questions your adviser is likely to ask
Expect a good adviser to ask what each project set out to achieve and why it was uncertain, who worked on it and for how long, how the time was recorded, what costs were incurred and how they were coded, and whether anything about the project changed during the year. They may ask whether similar work was claimed before and, if so, how it was described. Having answers ready, and written down, shortens the conversation and improves the claim.
Claims that span more than one year
Research projects often run across tax years. The same project may appear in several claims, with different costs each time. It helps to keep a continuous record per project, so that each year's claim can describe where the work stood and what happened during that year. The agent keeps evidence by project and date, which makes it easier to see a single year's activity within a longer story. How multi-year claims are handled in detail is a matter for your adviser.
