Eligibility and qualifying work
Whether your work qualifies is decided activity by activity against the four-part test - not by your industry, your size, or whether anyone calls it “research.”
Who can claim the federal R&D tax credit?
Any U.S. taxpayer that pays for qualifying research can claim it - C corporations, S corporations, partnerships, LLCs, and sole proprietors alike. There is no industry restriction and no minimum size. What matters is whether the activities pass the four-part test and the spending falls into a qualified research expense category. For pass-through entities the credit flows to the owners, where passive-activity and at-risk limits can affect how much is usable in a given year.
Do we have to invent something new to the world?
No. The statute asks whether you set out to create a new or improved business component and faced genuine technical uncertainty - measured against your own knowledge, not the state of the art. A competitor solving the same problem elsewhere does not disqualify you. What is excluded is straight duplication of an existing component under §41(d)(4)(C), which is a different thing from independently engineering your own solution.
What if the project failed or was abandoned?
Failure does not disqualify anything. Qualification turns on the process of experimentation, not the outcome, so an abandoned effort can qualify in full. In practice failed projects often produce the strongest evidence - the uncertainty was real, the alternatives were genuinely tested, and the record shows it. See the four-part test for how that evidence is structured.
Is software development eligible?
Yes - computer software is one of the business-component types named in §41(d)(2)(B). Software built for sale, lease, or license, or to be used by your customers, is evaluated like any other component. Software developed primarily for your own internal use faces an additional, higher threshold, so internal tooling needs a more careful analysis before it goes into a claim. Our SaaS and software page walks through what typically qualifies.
Our customer paid for the development - can we still claim it?
It depends on the contract, and this is the single most common place claims fail. Research is “funded,” and therefore excluded under §41(d)(4)(H), when payment is not contingent on the success of the research or when you do not retain substantial rights in the results. Fixed-price arrangements where you bear the technical and financial risk and keep rights to what you develop often still qualify; cost-plus terms that pay regardless of outcome and assign all rights to the customer often do not. Read the actual agreement before assuming either way.
Do SBIR or other grants disqualify our research?
Not automatically - the same funding analysis applies. Grant and award terms vary enormously in who bears the risk of failure and who retains rights to the results, and some structures leave meaningful rights with the company. This is a document-by-document review rather than a rule of thumb, and it is worth doing properly because the answer can move a large share of a claim.
Qualified research expenses
Four statutory categories drive the number. Everything else - however innovative - is outside the computation.
What expenses actually count?
Four categories under §41(b): W-2 wages paid for qualified services, supplies consumed in the research, amounts paid to rent or lease computers used in the research, and contract research paid to others. Contract research is generally included at 65% of the amount paid, with a 75% rate for qualified research consortia and a 100% rate only for energy research payments to eligible small businesses, universities, and federal laboratories under §41(b)(3)(D). Full detail is on the QRE page.
Do payments to outside contractors count?
Usually at 65%, provided the research is performed on your behalf, you bear the economic risk of failure, and you retain substantial rights in the results. One frequent misstatement is worth correcting: the requirement is that the qualified research be performed in the United States, not that the contractor be a U.S. company. Contracts and statements of work are the evidence, so they get read.
Do our cloud and compute bills count?
Amounts paid to rent or lease computers used in qualified research can be QREs under §41(b)(2)(A)(iii), and that reaches cloud compute used to run and host the research itself. Production hosting for a released product generally does not qualify, so a mixed environment needs a defensible split rather than a whole-invoice claim. Tagged accounts or environment-level billing make this straightforward; a single undifferentiated bill does not.
Can founder or executive time be included?
Yes, if the individual is actually performing, directly supervising, or directly supporting qualified research, and the compensation is W-2 wages. Guaranteed payments to partners and owner distributions are not wages and do not count. Note that Section E of the revised Form 6765 asks for the officers’ wages included in the claim, so an officer allocation should be as well supported as any other - see documentation.
What is specifically excluded?
§41(d)(4) lists the exclusions: research after commercial production begins, adaptation or duplication of an existing business component, surveys and studies, routine data collection and quality control, research in the social sciences, arts, or humanities, research conducted outside the United States, funded research, and most internal-use software absent a higher threshold being met. A study should screen for all of these before a dollar is counted, and say in writing why the ones a reader would raise do not apply.
Calculating the credit
Two computation methods, one election that changes your deduction, and carryover rules for the years you cannot use it.
Roughly how much is the credit worth?
As a rule of thumb the net federal benefit commonly lands somewhere around 6-10% of qualified research spending, depending on method, filing history, and the §280C election. That range is illustrative, not a quote - your result depends on your facts. The estimator gives you a rough number in about thirty seconds, entirely in your browser.
What is the difference between the Regular Credit and the ASC?
The Regular Credit is 20% of QREs above a fixed-base amount derived from your historical ratio of research spending to gross receipts. The Alternative Simplified Credit is 14% of QREs above 50% of the average QREs for the three preceding tax years - or 6% of current-year QREs if you had none in any of those three years. Which one wins depends on your history, and the difference is frequently large. See calculation methods.
Can we switch methods between years?
Generally yes, year by year - but the ASC is an election with its own timing rules. Treas. Reg. §1.41-9(b)(2), as amended by T.D. 9666, permits the ASC election on an amended return for an open year, but only if no §41 credit was previously claimed for that year on the original or an amended return - and once made, the election cannot be revoked by amendment. Those procedural details are why method selection belongs in the study, before filing, rather than in a conversation afterward. Confirm the current mechanics with your preparer for the specific year in question. See calculation methods.
What is the §280C reduced-credit election?
Claiming the credit ordinarily requires reducing your research deduction by the amount of the credit. §280C(c) instead lets you elect a reduced credit - computed net of the top corporate rate - and keep the full deduction. Which is better depends on your rate, your loss position, and your state treatment, so both should be modeled rather than defaulted. The election is made on an originally filed return.
What happens if we cannot use the credit this year?
The research credit is part of the general business credit, so an unused amount generally carries back one year and forward up to twenty. For a loss-making company that is real future value, not a lost benefit. A qualified small business may instead elect the payroll tax offset and convert the credit into near-term cash.
The payroll tax offset for startups
The §41(h) election is the reason a pre-revenue company should care about the credit at all - it pays out before you owe income tax.
What is the payroll tax offset?
Under §41(h) a qualified small business can elect to apply up to $500,000 of its research credit per year against employer payroll taxes instead of income tax. For a company with no income tax liability that turns the credit into actual cash. The full mechanics are on the payroll tax offset page.
Who counts as a qualified small business?
Broadly, a business with less than $5 million of gross receipts for the credit year that had no gross receipts in any tax year before the five-tax-year period ending with that year. The second condition surprises people: a long-dormant entity with early revenue can be disqualified even when it looks like a startup today. Both tests are applied to your specific facts and filing history.
How does the money actually reach us?
You make the election on Form 6765 with your income tax return, then claim the credit on Form 8974 filed with your quarterly employment tax return, beginning with the first quarter that starts after you file the return making the election. It offsets the employer share of Social Security tax first, and - for years after the Inflation Reduction Act change - the employer share of Medicare tax for the remainder. Anything you cannot use in a quarter carries to the next one.
Can we make the election on an amended return?
Generally no. The payroll tax election has to be made on an originally filed return, filed by the due date including extensions, which makes it one of the few R&D credit decisions that genuinely cannot be fixed later. There is also a lifetime limit on the number of years a business may make the election. If you are close to a filing deadline and think you may qualify, that is the moment to get it scoped.
Documentation and examinations
A credit is worth what you can substantiate. These are the questions that decide whether a claim holds up years later.
What documentation does a claim need?
§6001 and Treas. Reg. §1.41-4(d) require records in sufficiently usable form and detail to substantiate what you claimed - no particular format is prescribed. In practice that means evidence organized by business component: what was uncertain at the outset, which alternatives were evaluated, what was tested, who did the work, and how each dollar was allocated. Our documentation guide covers what belongs in that file and what examiners request.
We do not track time by project. Is that fatal?
No, but it changes the work. Wage allocations can rest on system-derived evidence - tickets, commits, change orders, travelers, lab notebooks - or on structured interviews corroborated by dated artifacts from the same period. What does not hold up is a flat departmental percentage with nothing behind it. Most companies already generate the raw material and simply have not mapped it to business components.
What is Form 6765 Section G?
Section G is the business-component reporting block added by the December 2024 revision of Form 6765: for each reported component you give its name, type, the information sought to be discovered, and the QREs assigned to it by category. Per the current instructions it is optional for tax years beginning before 2026 and required for tax years beginning after 2025, with exceptions for certain qualified small businesses and smaller filers - check the current-year instructions, because these thresholds have already been revised once. A study organized by component populates it directly; one built on department totals has to be rebuilt. See documentation.
How likely is an examination?
We do not publish an audit-rate figure, because no reliable public statistic exists for research credit examinations specifically, and vendors who quote one are estimating. What is knowable is the pattern: the research credit is a recurring IRS focus area, examinations open with document requests, and the questions land at the business-component level. Build for that and the probability stops being the interesting number.
What happens if the IRS examines our credit?
Every Ricerca study includes Audit Protection. We prepare the audit response, assemble the documentation the examiner requests, and defend the technical positions in the study, working alongside your tax preparer. Representation before the IRS, where it is needed, is performed by credentialed practitioners. Coverage is limited to the R&D study and the related federal credits, under your engagement agreement, and depends on the accuracy and completeness of the information you provide.
Prior years, amended returns, and timing
What you can still go back and claim, and when in the year it makes sense to start.
Can we claim credits for prior years?
Generally yes, for tax years still open under the refund statute of limitations - usually about three years from filing, with the precise window set by §6511 and your own filing and payment dates. Prior-year claims are worth evaluating whenever the research was real and simply never studied. Whether a specific year is open is a question for your preparer, not a rule of thumb.
Is there extra paperwork for an amended R&D claim?
Yes. A research credit claimed on an amended return is a refund claim, and the IRS requires specified information for the claim to be considered valid - identifying the business components involved, the research activities performed for each, and the total qualified wage, supply, and contract-research expenses. Two earlier items, naming the individuals who performed each activity and the information each sought to discover, were waived for refund claims filed on or after June 18, 2024. This guidance has been revised more than once, so check current IRS guidance before filing.
When during the year should we start a study?
Earlier is better, for two reasons that have nothing to do with our calendar. Elections that matter - the ASC, §280C, and the §41(h) payroll offset - generally have to be made on an originally filed return, so they disappear once the return goes out. And a study started before year-end can influence what gets captured while the work is still happening, which is worth more than any amount of reconstruction. See how a study runs.
State credits and §174A
The federal credit is one of three benefits that come off the same substantiated base of research spending.
Do states offer their own R&D credits?
Most states with a corporate income or franchise tax run one, including Pennsylvania, and many compute from the same QRE base as the federal credit - which means one well-built study can support several filings. Rates, refundability, transferability, and carryforward rules vary widely by state, and some programs are capped or require an application by a fixed date. See state R&D credits for how we handle them.
What is §174A and how is it different from the credit?
§174A is a deduction rule, not a credit: enacted by the One Big Beautiful Bill Act in July 2025, it restores immediate expensing of domestic research and experimental costs for tax years beginning after December 31, 2024. Foreign R&E must still be capitalized and amortized over fifteen years. The credit and the deduction are separate benefits and you can take both - see the §174A guide.
We capitalized R&D in 2022-2024. Can we still recover that?
Through the catch-up deduction, yes: the remaining unamortized domestic balance can generally be deducted in full in the first tax year beginning after December 31, 2024, or ratably across 2025 and 2026. The separate small-business option to amend 2022-2024 returns generally closed on July 6, 2026, and only narrow situations tied to a still-open refund statute may remain. Confirm your specific position with a qualified professional before assuming one applies.
Does claiming the credit reduce our §174A deduction?
It can. Under §280C(c) you either reduce the research deduction by the amount of the credit or elect the reduced credit and keep the deduction intact. The better answer depends on your tax rate, your loss position, and how your states conform, which is why both should be modeled on your actual numbers rather than chosen by habit.
Working with Ricerca
How the engagement runs, what you receive, and where we fit alongside the people you already work with.
How long does a study take?
Typically weeks rather than months, depending on your size and how readily your payroll, general-ledger, and project data can be pulled. AI compresses intake, mapping, and drafting; our R&D experts review and finalize every study before it is issued. The realistic constraint is usually how fast the data arrives, not how fast we work - see how it works.
What does a study cost?
Pricing is quoted for your study after a short scoping conversation, because the work scales with the number of business components, the size of the claimed population, and the state of your data. You see the scope and the price before anything starts, and the conversation itself is free with no obligation. Tell us about your R&D and we will come back with both.
Do you replace our CPA or tax preparer?
No, and we would not want to. Ricerca is an R&D tax credit specialist: we perform the study, produce the substantiation, and hand your preparer filing-ready figures and forms. Your CPA or tax preparer files the return. Firms that would rather run studies for their own clients can work with us directly through the CPA Firm Portal - see why Ricerca.
What do we actually receive at the end?
A study report with technical narratives per business component, QRE workpapers that reconcile to your payroll and general ledger, filing-ready Form 6765 including the Section G detail, Form 8974 where the payroll offset applies, a pro-forma Form 3800, and an organized audit file. It is built so your preparer can file from it and an examiner can read it. The platform page shows how it is produced.
Is our data safe, and do you train AI on it?
Your confidential information is never used to train public or third-party AI models - it is used only to perform your study. Data is encrypted in transit and at rest, access is limited to the people working on your engagement, and the AI routing we use is enterprise-grade rather than consumer. Details are on the security page.
