7 Things the New Form 6765 Wants to Know About Your R&D Credit
Sam's List Editorial | 2026-09-02
The research credit used to be a number you handed to your accountant in February.
Starting with tax years beginning after 2025, it becomes a list of projects, each with a name, a type, and a wage breakdown split three ways. Form 6765 Section G is optional for tax year 2025 and required for tax year 2026, which for a calendar-year company means the work you are doing right now has to be documented in a way it probably is not.
Source: Instructions for Form 6765 (Rev. December 2025).
One correction up front, because it is everywhere. The IRS originally announced Section G would apply to tax year 2025. That was superseded by IR-2025-99 in October 2025, which made Section G optional for all filers for tax year 2025 and mandatory for tax year 2026 and beyond. If your adviser told you last year that 2025 was the deadline, they were reading the older release.
1. Every Business Component, By Name
Section G asks you to list your business components. A business component is any product, process, computer software, technique, formula, or invention you hold for sale, lease, or license, or use in your own trade or business.
Column 49(c) wants the name or a unique alphanumeric identifier, and the instructions add a condition that matters: it has to be consistent with the books and records substantiating your qualified research expenses.
That is the actual requirement hiding in a formatting instruction. Whatever you call a project on the form has to be traceable to how the cost was recorded. If engineering tracks work by ticket and payroll tracks it by department and neither maps to what appears on the return, you have a reconciliation problem to solve before the filing, not during it.
2. What Type It Is, and Only Three Choices
Column 49(d) asks for the business component type, and there are exactly three options: Product, Process, or All Others. All Others is the catchall for computer software, techniques, formulas, and inventions.
If it is software, column 49(e) then asks which kind: internal use software, dual function software, non-internal use software, or excepted from internal use software treatment.
For a company building its own platform, that internal use software classification is not a clerical choice. It determines which set of rules the expense has to clear, and it is now a checkbox on the return.
3. Wages, Split Three Ways
This is the line item most likely to expose a weak process.
Section G does not ask for total qualified wages per project. It asks for three separate numbers per business component:
- Column 50: direct research wages, for people doing the work
- Column 51: direct supervision wages, for people supervising it
- Column 52: direct support wages, for people supporting it
Column 53 totals them and has to tie to the wage figure in Section F. Columns 54 through 56 do the same for supplies, computer rental or lease costs, and contract research.
A time-tracking system that captures hours by project but not by role does not produce these numbers. That is the gap to close this year.
4. The 80% and Top 50 Rule on Form 6765
You do not have to list everything. The instructions require completing the Section G columns for at least 80% of your total qualified research expenses by business component, reporting no more than 50 business components, listed in descending order of QREs per component. Whatever is left over goes on a single line labeled "Aggregate Business Components" with the totals filled in and the other columns blank.
Two practical consequences:
- You cannot decide which projects to report. The ordering is mechanical, driven by spend, so your largest research spends are always the ones under the most detail.
- You need per-component QRE totals just to know which components make the cut. That calculation itself is the new work.
Taxpayers using the ASC 730 Directive get a special rule: a single Section G entry labeled "ASC 730 Directive" with the applicable amounts, and that entry does not count against the Top 50. The Directive is only available to taxpayers with assets of $10 million or more who follow US GAAP for certified audited financial statements.
5. Who Gets to Skip Section G Entirely
Two exemptions, per the instructions:
- You are a qualified small business under section 41(h)(3) and you checked the box to claim the reduced payroll tax credit; or
- Your total QREs at the controlled group level are $1.5 million or less, and your average annual gross receipts for the prior three tax years are $50 million or less, and you are reporting the credit on an original return.
Read that last condition twice. The small-filer exemption evaporates on an amended return. A company that files a clean original return skips Section G; the same company amending to claim the credit later does not.
6. The Narrative Field Is an Amended-Return Penalty
Column 49(f) asks you to describe the information sought to be discovered. That is the qualitative narrative, and it is the hardest field to write well.
The instructions carry an explicit caution: you are not required to complete column 49(f) for timely filed original tax returns including extensions. It is required on an amended return or administrative adjustment request that claims a credit not reported on the original return, or that increases the credit from the amount originally reported. An amended return that does not increase the credit is not caught.
So the form is quietly priced. Get the number right on the original return and you skip the narrative. Go back and claim more later and you write it, for every reported component.
That is a real incentive to get the credit right the first time.
7. Section 174A Changed the Deduction Side Underneath All of This
While the credit form got longer, the deduction rules moved.
The One Big Beautiful Bill Act added new section 174A, which allows taxpayers to deduct domestic research or experimental expenditures in tax years beginning after December 31, 2024, reversing the capitalization regime that had companies amortizing their own engineering salaries. Foreign research is still capitalized and amortized over 15 years.
There was also a look-back, and one door on it has already closed. A small business taxpayer, meaning one meeting the section 448(c) gross receipts test, could elect to apply the change to amounts paid or incurred in tax years beginning after December 31, 2021, expensing 2022 through 2024 domestic research retroactively. Under Rev. Proc. 2025-28, that election had to be made by July 6, 2026, so it is no longer available. What remains: any taxpayer can still elect to recover remaining unamortized 2022 through 2024 domestic costs either fully in the first tax year beginning after 2024 or ratably over two years, and the accounting method change route under section 70302(f)(1)(C) may still be open. Those are date-sensitive and worth confirming with your CPA rather than reading off a blog.
And the Section 280C election still forces a choice. Elected at the top of Form 6765, on the original timely filed return only, irrevocable for that year: take a reduced credit of 15.8% instead of 20% under the regular method, or 79% of the computed alternative simplified credit, and keep your full deduction. Do not elect it, and you must reduce your section 174A research deduction by the amount of the credit. You cannot have both at full value.
The Form 6765 R&D Credit Payroll Offset, For Companies With No Tax Bill
If you are pre-profit, the credit still has cash value. A qualified small business, meaning generally a company with gross receipts under $5 million for the year and no gross receipts before the five-tax-year period ending with the tax year, can elect to apply up to $500,000 of the research credit against the employer portion of Social Security tax. The Inflation Reduction Act raised that cap from $250,000 for tax years beginning after December 31, 2022.
The election is annual, must be made by the due date of the original return including extensions, and cannot be made if you have already made it for five or more preceding years. It is claimed on Form 8974, attached to your employment tax return, starting with the first quarter that begins after you file the income tax return making the election.
The limitation worth stating plainly: this is a timing and cash-flow benefit with real administrative overhead, and it does not turn an unprofitable company into a profitable one.
What Section G Wants, In One Table
| Column | What it asks for | Where it usually breaks |
|---|---|---|
| 49(c) | Business component name or identifier | Names do not tie to the books and records |
| 49(d) | Product, process, or all others | Everything gets coded the same way |
| 49(e) | IUS, DFS, non-IUS, or excepted | Software projects miscategorized |
| 50 to 52 | Wages split into research, supervision, support | Time tracked by project but not by role |
| 53 to 56 | Totals, supplies, computer rental, contract research | Totals do not tie to Section F |
| 49(f) | The information sought to be discovered | Written after the fact, on an amended return |
Where a Form 6765 R&D Credit Specialist Earns the Fee
Most of the above is documentation architecture, not tax planning, and it has to be built during the year rather than reconstructed after it.
Ursa Consultants is an accounting firm whose stated client specialty is venture-backed startups. That focus is the relevant qualification here, because the companies most exposed to Section G are exactly the ones with engineering payroll as their largest expense and the least mature project accounting.
The honest caveat: no firm can retroactively create time records that were never kept. If 2026 is already half over and nobody is tracking wages by role and component, the useful conversation is about what can still be captured for the rest of the year.
Before you hire anyone for this, ask two questions. Can they describe how they would map your engineering time tracking to Section G's three wage lines? And will they tell you if you are better off skipping the credit than claiming one you cannot substantiate?

Frequently Asked Questions
When does Form 6765 Section G become mandatory? Section G is optional for all filers for tax years beginning before 2026 and required for tax years beginning after 2025. For a calendar-year company that means the 2026 return, filed in 2027. An earlier IRS release naming tax year 2025 was superseded by IR-2025-99 in October 2025.
Do I have to list every R&D project on Form 6765? No. You report business components in descending order of qualified research expenses until you cover at least 80% of total QREs, capped at 50 components, and put the remainder on one aggregated line. You still need per-component QRE totals to determine the ordering.
Who is exempt from Section G reporting? Qualified small businesses under section 41(h)(3) that check the box to claim the reduced payroll tax credit, and filers whose total QREs at the controlled group level are $1.5 million or less with three-year average gross receipts of $50 million or less, provided they are reporting on an original return.
Can I still deduct R&D costs instead of amortizing them? For domestic research or experimental expenditures, yes, in tax years beginning after December 31, 2024, under new section 174A. Foreign research is still amortized over 15 years. The retroactive election back to tax years beginning after December 31, 2021 was available to small business taxpayers but closed on July 6, 2026. The election to recover remaining unamortized 2022 through 2024 domestic costs, either fully or over two years, is still available.
