Form 6765, Credit for Increasing Research Activities, is the IRS form used to figure and claim the federal R&D tax credit under Section 41 of the Internal Revenue Code. This page explains, in general terms, what the form is, what it is used for, and the kinds of information it organizes. It is not a substitute for the current form and instructions, which control how to complete it for a given tax year.
Form 6765 in Plain English
According to the IRS, Form 6765 is used to figure and claim the credit for increasing research activities, to elect the reduced credit under Section 280C, and to elect and figure the qualified small business payroll tax credit. In other words, the form is the reporting mechanism through which a taxpayer computes the credit and makes certain related elections. The credit itself is established by statute — Section 41 — and the form is the administrative vehicle for claiming it.
What Form 6765 Is Used For
The Instructions for Form 6765 describe the form's sections, which generally organize the following kinds of information:
- computing the credit under the regular method and the alternative simplified credit (ASC) method;
- summarizing qualified research expenses (QREs) — certain wages, certain supplies, and certain contract research;
- reporting business-component information; and
- making the qualified small business payroll tax election and figuring the payroll tax credit.
The form also accommodates the Section 280C reduced credit election. The specific lines and sections can change over time, so the current form and instructions are the authoritative reference for how to complete it.
How Form 6765 Relates to the R&D Tax Credit
The credit for increasing research activities is a tax benefit associated with qualified research activities and qualified research expenses that meet the requirements of Section 41. Form 6765 is where the resulting computation is reported. The form does not itself determine whether research qualifies — that determination depends on whether the activities satisfy the four-part test and whether the costs meet the applicable rules. For more on the underlying concepts, see our pages on what the R&D tax credit is and qualified research expenses.
Qualified Research Expenses on Form 6765
The form summarizes qualified research expenses, which generally fall into three categories: certain in-house employee wages, certain supplies, and certain contract research expenses. The Instructions for Form 6765 address how these expenses are reported, including by business component. Not every wage, supply, or contractor cost is automatically a QRE — the costs must be connected to qualified research activities and meet the applicable requirements. For more, see our pages on employee wages, contractor costs, and supplies.
Regular Credit vs. Alternative Simplified Credit
The Instructions for Form 6765 describe two principal methods for computing the credit:
- Regular credit — generally based on qualified research expenses for the taxable year over a base amount.
- Alternative simplified credit (ASC) — generally based on qualified research expenses for the taxable year over a percentage of the average qualified research expenses for a prior period.
The IRS describes the regular credit as generally equal to 20 percent of the excess of the taxpayer's qualified research expenses for the taxable year over the base amount, and the alternative simplified credit as generally equal to 14 percent of the qualified research expenses for the taxable year over 50 percent of the average qualified research expenses for the three taxable years preceding the credit year. The specific computation, base-period rules, and limitations are set out in Section 41 and the current instructions, and which method is more favorable depends on a taxpayer's facts.
Reduced Credit Election, if Supported by Current Instructions
The form is also used to elect the reduced credit under Section 280C. The Instructions for Form 6765 address this election, including how it is indicated on the form. The election has specific consequences that are described in the instructions and the statute, and whether it is appropriate depends on a taxpayer's circumstances. This page does not summarize those consequences in detail because they can be technical and fact-dependent; readers should consult the current instructions and professional review.
Payroll Tax Election for Qualified Small Businesses
A qualified small business may elect to apply a portion of the research credit against payroll tax rather than income tax. The election is made on Form 6765 and is designed to benefit eligible startups that have little or no income tax liability. The payroll tax election has specific eligibility requirements and limits under Section 41(h), and the credit is claimed on employment tax returns using Form 8974. For more, see our page on the R&D payroll tax credit.
Business Component Information / Current Reporting Requirements
The Instructions for Form 6765 include reporting of business-component information — generally describing the business components to which the credit relates and the associated qualified research expenses. The instructions distinguish reporting requirements for tax years beginning before 2026 and for tax years beginning after 2025, and the specific columns and entries can change over time. Because these reporting details evolve, readers should consult the current Instructions for Form 6765 for the requirements that apply to a given tax year rather than relying on a static summary.
Why Documentation Matters Before Preparing the Form
Preparing Form 6765 is generally easier and more defensible when the underlying activities, costs, and business components have been documented during the year. Records connecting qualified research activities, costs, and business components support the figures reported on the form and help a business respond if the IRS asks questions. The IRS has published guidance on the information it expects in connection with research credit claims. For more, see our page on R&D tax credit documentation.
Form 6765 Is Not the Same as Determining Qualification
A common misunderstanding is that completing Form 6765 establishes that research qualifies for the credit. It does not. The form is a reporting and computation tool; the substantive question of whether activities constitute qualified research, and whether costs are qualified research expenses, is governed by Section 41, the Treasury Regulations, and IRS guidance, and turns on the specific facts. Completing the form accurately depends on having already made those substantive determinations, ideally with professional review.
Key Takeaway
Form 6765 is the IRS form used to figure and claim the R&D tax credit, to elect the reduced credit under Section 280C, and to elect and figure the qualified small business payroll tax credit. It organizes the computation of the credit and the reporting of qualified research expenses and business-component information, but it does not determine whether research qualifies. The current form and instructions are the authoritative reference for completing it, and filing decisions should be made with professional review.
