A tax credit questionnaire is an internal screening document a business uses to test whether it qualifies for a specific federal or state tax credit before committing to full documentation and filing. It is not an IRS form. It’s a due diligence tool, usually built by a third-party tax credit administrator or an in-house tax team, that collects the facts needed to evaluate eligibility for credits such as the Work Opportunity Tax Credit (WOTC), the research and development credit under Section 41, or energy investment credits under Section 48. Filling it out creates an auditable paper trail showing the company assessed eligibility in a structured way before claiming anything on a return.
Why the Questionnaire Exists
It does two jobs at once. First, it filters. Employees, projects, or assets that clearly don’t qualify get sorted out before anyone spends hours pulling payroll records or writing up project narratives. Second, it documents. If the IRS later questions the credit, the completed questionnaire is contemporaneous evidence that the taxpayer made a genuine effort to determine eligibility before filing, which is the foundation of the reasonable cause defense against accuracy-related penalties.
Most businesses meet these questionnaires through third-party administrators who specialize in identifying and processing credits, often on a contingency fee tied to the credit they recover. The questionnaire is their intake step: enough information to decide whether a deeper engagement is worth the time. Whoever administers it, the document formalizes the gap between “we might qualify” and “here are the facts that support our claim.”
WOTC Questionnaire: What It Asks For
The Work Opportunity Tax Credit rewards employers for hiring individuals from ten targeted groups that face significant barriers to employment, including veterans, SNAP recipients, SSI recipients, individuals with felony convictions, long-term unemployment recipients, and TANF recipients.1U.S. Department of Labor. Work Opportunity Tax Credit
A WOTC questionnaire captures the facts needed to confirm targeted-group membership and to run the credit math:
- Employee demographics that establish membership in a targeted group, such as veteran status, public assistance history, or a prior felony conviction.
- The hire date. This one is time-critical. The employer must submit IRS Form 8850 to the state workforce agency within 28 calendar days of the employee’s start date to request certification. Miss the window and the credit is gone for that hire, with no way to request certification retroactively.2U.S. Department of Labor. How to File a WOTC Certification Request3Internal Revenue Service. Employers Should Certify Employees Before Claiming the Work Opportunity Tax Credit
- Hours worked in the first year. At 400 hours or more, the credit equals 40% of qualified first-year wages. Between 120 and 399 hours, it drops to 25%.4Internal Revenue Service. Work Opportunity Tax Credit
- Qualified wages paid, up to a cap that varies by targeted group. For most groups, only the first $6,000 in wages counts, producing a maximum credit of $2,400 per employee. For certain qualified veterans, up to $24,000 in wages may count, pushing the maximum to $9,600.4Internal Revenue Service. Work Opportunity Tax Credit
Because of the 28-day rule, a WOTC questionnaire really belongs inside the onboarding process, not the tax cycle. Hire-date and demographic data need to be captured immediately or the credit dies before anyone runs a calculation.
R&D Credit Questionnaire: What It Asks For
For the research credit under Section 41, the questionnaire shifts from employee data to projects and expenses. It asks two things: do these projects qualify, and how much did the company spend on them.
Project Qualification
Under Section 41(d), a qualifying activity must involve expenditures treated as research expenses, aim to discover information that is technological in nature, be intended to develop a new or improved business component, and substantially involve a process of experimentation for a qualifying purpose such as new functionality, improved performance, or better reliability. Work related to style, taste, or cosmetic design is out.5Office of the Law Revision Counsel. 26 U.S. Code 41 – Credit for Increasing Research Activities
The questionnaire asks for narrative descriptions of each project: the uncertainty that existed, the alternatives the team evaluated, and the experimentation that resolved it. This is where R&D credit claims most often fall apart. Project documentation reconstructed at tax time carries far less weight than contemporaneous records — the project logs, design notes, and test results generated while the work was actually happening.
Qualified Research Expenses
Once a project qualifies, the questionnaire drills into the expenses tied to it. Qualified research expenses fall into three categories: wages paid to employees performing qualified research, supplies consumed during the research, and 65% of amounts paid to outside contractors for research work.5Office of the Law Revision Counsel. 26 U.S. Code 41 – Credit for Increasing Research Activities The questionnaire needs enough detail to run the calculation under both the regular method and the alternative simplified credit, so the preparer can pick whichever produces the larger benefit.
Energy Credit Questionnaires
For energy investment credits under Section 48, the focus moves to assets. The questionnaire collects the purchase date, the placed-in-service date, and total installation and capital costs, along with documentation that the property meets applicable performance and quality standards — a condition of eligibility under Section 48.6Office of the Law Revision Counsel. 26 U.S. Code 48 – Energy Credit
Bonus credit amounts on many energy projects depend on prevailing wage and apprenticeship compliance, so the questionnaire typically adds labor questions to the asset data. Failing the labor requirements can cut the credit to one-fifth of the full amount.
How the Answers Turn Into a Credit
Once the questionnaire is complete, the reviewer (a third-party administrator or the internal tax team) cross-references the answers against source documents — payroll records, project logs, invoices — to confirm internal consistency before running the math.
Verified data feeds the specific IRS forms for each credit. WOTC amounts go on Form 5884; R&D credit amounts go on Form 6765.7Internal Revenue Service.

The Deduction Offset
Claiming the credit doesn’t mean the company also deducts the same expenses that generated it. Under Section 280C, otherwise-allowable deductions must be reduced by the amount of certain credits claimed. For the WOTC, wages equal to the credit amount can’t be deducted. For the R&D credit, research expenditures must be reduced by the credit amount.12Office of the Law Revision Counsel. 26 U.S. Code 280C – Certain Expenses for Which Credits Are Allowable It’s baked into the math, but it surprises businesses that assume the credit is pure upside.
What a Weak Questionnaire Costs
An incomplete or inaccurate questionnaire risks more than the credit itself. The accuracy-related penalty under Section 6662 adds 20% of the underpayment when the IRS finds the taxpayer was negligent or substantially understated tax liability.13Office of the Law Revision Counsel. 26 USC 6662 – Imposition of Accuracy-Related Penalty on Underpayments Where fraud is involved, the penalty under Section 6663 jumps to 75% of the underpayment attributable to the fraud, and once any portion is proven fraudulent, the entire underpayment is treated as attributable to fraud unless the taxpayer proves otherwise.14Office of the Law Revision Counsel. 26 USC 6663 – Imposition of Fraud Penalty
The main defense against the accuracy-related penalty is reasonable cause and good faith. The IRS looks at the taxpayer’s overall effort to determine the correct liability, including reliance on professional advice and whether that reliance was reasonable.15eCFR. 26 CFR 1.6664-4 – Reasonable Cause and Good Faith Exception to Section 6662 Penalties A well-documented questionnaire completed before filing is exactly the evidence that supports this defense. One assembled after the fact, or one whose answers don’t line up with source records, undermines it.
The Records Behind the Questionnaire
The questionnaire is only a summary. Its value depends on whether the underlying records still exist when the IRS asks: certified payroll, WOTC certification letters from the state workforce agency, vendor invoices for research expenses, and internal project logs with real-time detail about research activities.
The general rule is to keep records at least three years from the date the return was filed or its due date, whichever is later.16Internal Revenue Service. How Long Should I Keep Records Because general business credits can be carried forward up to 20 years, a company using carryforwards should retain documentation from the original credit year until three years after filing the return on which the carryforward is finally used. The burden of proof rests with the taxpayer, and losing the records during an examination is functionally the same as never having qualified.17Internal Revenue Service. Topic No. 305, Recordkeeping
