How to Conduct a Pay Equity Audit: A Step-by-Step Guide

The Employment Attorney's Friday Afternoon Question

Picture this: it is 4 p.m. on a Thursday. Your employment attorney emails to say she is reviewing your pay practices ahead of a contract bid that requires an EEO certification. She needs, by end of week, a list of every job title, the salary range attached to it, and the methodology you used to set those ranges. She also wants to know whether anyone in those roles is currently paid below the range minimum, and why.

You open a shared spreadsheet. The ranges are a patchwork — some set by a hiring manager's gut feel three years ago, some borrowed from a job posting on a competitor's website, a few never updated since a reorg. Some employees do not map to any range at all. There is no documentation of methodology. There is no audit trail.

That is the moment most SMB HR teams wish they had already run a pay equity audit.

A pay equity audit — a structured review of whether employees in comparable roles are paid equitably relative to one another and relative to a documented market anchor — is both a legal risk-management tool and a workforce-integrity tool. By the end of this guide, you will have a repeatable six-step method you can run with the data your organization already holds, anchored in defensible BLS wage benchmarks, and documented in a format you can hand to counsel or a regulator.

What a Pay Equity Audit Actually Is (and Is Not)

Before the first step, two definitions worth getting precise.

Pay equity refers to the principle that employees performing comparable work should receive comparable compensation, absent legitimate, documented, job-related distinctions such as experience, geography, or scope of responsibility. It is related to — but distinct from — the gender pay gap (a population-level statistic comparing median earnings across genders) and from pay transparency (the obligation to disclose salary ranges in job postings). All three intersect, but a pay equity audit addresses the internal structure: are your own employees paid fairly relative to each other and to a consistent market anchor?

A pay equity audit is not legal advice. It is a structured analytical process that surfaces pay anomalies and creates documentation. What your organization does with those findings — including whether and how to remediate — involves legal and business judgment. Involve employment counsel, particularly in states with active equal-pay enforcement. For a broader overview of the pay-transparency and equal-pay laws that frame this work, see our pay equity laws overview.

With that framing in place, here is the six-step process.

Step 1: Define the Scope and Assemble the Data

Every pay equity audit begins with a clean roster. You need, for every active employee:

• Job title (the working title used in HR records)
• Job family (the functional grouping: Engineering, Finance, Operations, etc.)
• Level or grade (if your organization uses levels — L1, L2, Senior, Manager, etc.)
• Employment type (full-time, part-time, exempt, non-exempt)
• Geography (state and city, especially for remote workers who may sit in a pay-transparency jurisdiction — see the pay equity laws overview for which states currently require posted ranges)
• Current base salary or hourly rate
• Date of last compensation adjustment
• Protected characteristics — gender, race/ethnicity, age — collected only through voluntary self-identification in your HRIS, used solely for aggregate disparity analysis, and handled with appropriate access controls

On the EEOC's role: the Equal Employment Opportunity Commission enforces federal equal-pay protections under Title VII, the Equal Pay Act, the Age Discrimination in Employment Act, and the ADA. Employers with 100 or more employees (and federal contractors with 50 or more) are required to file EEO-1 Component 1 data annually; the EEOC periodically collects pay data (Component 2) when authorized. SMBs below the 100-employee threshold are generally not subject to mandatory EEO pay-data reporting, but they remain subject to substantive equal-pay obligations under federal law and, increasingly, under state equal-pay statutes. Always confirm your specific reporting and compliance obligations with the EEOC (eeoc.gov) and with the relevant state labor agency or legal counsel — requirements and enforcement posture change.

Practical note on data quality: before you can analyze pay equity, you need clean job mapping. If two employees doing the same work carry different titles because their hiring managers improvised, the audit will produce false positives. Spend time now reconciling titles to a consistent job architecture. This is not overhead — it is the audit.

Step 2: Build or Validate Defensible Salary Ranges

A pay equity audit without an external market anchor is just an internal consistency check. It tells you whether employees are paid similarly to each other, but not whether those rates are defensible relative to the labor market. The market anchor is what makes a range auditable by an attorney or a regulator.

Salary range terminology, defined once:

• Range minimum: the lowest pay the organization will offer for a role (often set at or near the 25th percentile of the market, or lower for entry-level progression roles).
• Range midpoint: the target rate for a fully competent, experienced incumbent — typically anchored to the market median (the 50th percentile of wages for that occupation and geography in the BLS OEWS dataset), meaning the wage level below which half of workers in that occupation earn.
• Range maximum: the ceiling of the band, typically set at a fixed range spread above the midpoint. Range spread is how wide the band is, expressed as a percentage of the midpoint (or, in some frameworks, of the minimum). A 50% spread from min to max is common for professional roles; narrower spreads (30–40%) are typical for highly structured, lower-variance roles.
• Compa-ratio: an employee's current pay divided by the range midpoint, expressed as a percentage. A compa-ratio of 100% means the employee is paid exactly at midpoint. Below 80% often warrants scrutiny; above 120% may indicate the range needs updating or the incumbent has outgrown the level. For a full explanation, see our compa-ratio guide.

Where the market data comes from: The U.S. Bureau of Labor Statistics Occupational Employment and Wage Statistics (OEWS) program produces annual wage estimates for over 800 occupations, drawn from a sample of approximately 1.1 million establishments (BLS, May 2025). The May 2025 OEWS national, state, and metro estimates were released May 15, 2026 (BLS, 2026). Always confirm the release date and reference year of the figures you use at bls.gov/oes, since estimates are updated annually.

To illustrate how a range is constructed from BLS data: the national median wage for Accountants and Auditors (SOC 13-2011) was $81,680 (BLS OOH, May 2024). A simple ±20% spread around that midpoint produces a range of approximately $65,344 (minimum) to $98,016 (maximum). That arithmetic is a worked example of a method, not a BLS-reported figure; your organization's actual spread choices should reflect role scope, market position, and any union or contractual constraints. For the full methodology, see how to build a salary range and salary range midpoint explained.

If your ranges were set without a documented BLS or equivalent anchor, this step is where you rebuild them. An undocumented range cannot be defended in an audit.

Step 3: Map Every Employee to a Range — and Flag the Outliers

With clean job data and validated ranges, the core analytical work begins. For each employee record:

1. Assign the applicable range (by job family, level, and geography).
2. Calculate the compa-ratio (current base salary ÷ range midpoint × 100).
3. Calculate range penetration — where the employee sits within the band, expressed as a percentage from minimum to maximum. Range penetration of 0% means the employee is at the range minimum; 100% means they are at the maximum. An employee below 0% is paid below the range minimum — a red flag requiring immediate explanation and, in many cases, remediation.
4. Flag any employee paid below the range minimum. This is not necessarily evidence of discrimination, but it is always a finding that requires a documented, legitimate explanation (recent hire in a graduated pay schedule, an apprenticeship wage, a documented performance plan) or remediation.
5. Flag statistical outliers within peer groups. Employees in the same job family, level, and geography whose pay differs from the peer-group midpoint by more than one standard deviation warrant a documented explanation — not automatic remediation, but scrutiny.

For a detailed walkthrough of how to read and act on range penetration data in a dashboard context, see our range penetration dashboard guide.

The protected-characteristic overlay: once outliers are flagged on the basis of range position, overlay the voluntary self-identification data. The question is whether employees sharing a protected characteristic (gender, race/ethnicity) cluster disproportionately in the below-midpoint or below-minimum segments of any job family or level. This is an aggregated, pattern-level analysis — not a conclusion about any individual's protected status driving their pay. If the data shows a statistically meaningful pattern, that is a finding, and it warrants legal review before any communication to employees.

Step 4: Identify Legitimate Compensable Factors — and Document Them

Not every pay difference is a pay equity problem. Federal equal-pay law (the Equal Pay Act) and most state equivalents permit pay differences based on:

• Seniority — documented time in role or in the organization
• Merit — documented performance ratings, tied to a consistent, applied performance management process
• Production or incentive factors — commission or piece-rate structures
• Any other bona fide factor not based on a protected characteristic — geographic cost-of-labor differentials, specialized certifications, scope of responsibility, market-specific scarcity premiums

The critical word is documented. A hiring manager's recollection that "Sarah just negotiated harder" is not a compensable factor. A documented geographic differential, applied consistently and reflected in the range itself, is. In a pay equity audit, the goal is to match every pay difference to one or more of these factors, with supporting documentation — offer letters, performance reviews, job descriptions, range-setting worksheets.

Any pay difference that cannot be matched to a documented, legitimate compensable factor is a gap. Gaps are findings. Findings require a response — either remediation (a pay adjustment) or a documented rationale for why remediation is deferred and when it will occur.

This is also the step where your methodology documentation earns its value. Employment attorneys and regulators will ask: "How did you set these ranges, and how do you apply them consistently?" Your BLS OEWS anchors, your range-spread logic, and your job architecture are the answer. An undocumented methodology is, effectively, no methodology.

---

Step 5: Produce a Written Findings Report

The output of a pay equity audit is not a spreadsheet. It is a written findings report — a document that can be reviewed by employment counsel, provided to a regulator on request, or used to brief leadership on remediation costs and timelines.

A well-structured findings report includes:

Executive summary. Scope of the audit (employee count, job families covered, date of data snapshot), methodology (BLS OEWS reference year and release, range-spread approach, compensable-factor framework), and a summary of findings (number of employees below range minimum, number of outliers flagged, protected-characteristic patterns identified, if any).

Findings by job family. For each job family: range parameters (min/mid/max, source, reference year), employee count, compa-ratio distribution, range penetration distribution, flagged outliers, and documented explanatory factors or open gaps.

Remediation schedule. For every open gap: the employee or role (anonymized or identified, depending on your legal counsel's guidance), the nature of the gap, the proposed remediation action, the cost estimate, and the target effective date.

Methodology appendix. The BLS OEWS data used (occupation, SOC code, geography, release year), the range-spread framework, and the compensable-factor definitions. This is the document your attorney will want.

A pay equity audit is most defensible when it is conducted before a complaint or investigation is filed. Proactive documentation of methodology is far stronger than reactive reconstruction.

Maintain this report as a confidential legal document. Depending on your jurisdiction and whether you have involved counsel, it may be protected by attorney-client or work-product privilege — confirm the appropriate handling with your legal team.

Record retention: some jurisdictions specify how long compensation records must be retained. Illinois, for example, requires employers to retain pay-scale and posting information for each position for five years (Greenberg Traurig / Illinois DOL, 2024). California's Labor Code §432.3 requires employers to maintain job-title and wage-rate history records (Employment Law Aid citing CA Labor Code §432.3, 2026). Confirm the applicable retention requirements for every state where you have employees with the relevant state labor agency or legal counsel — requirements vary and change.

Step 6: Set a Remediation Budget and a Review Cadence

A pay equity audit is not a one-time event. Pay equity drifts — through off-cycle adjustments, promotions without range checks, new hires negotiated above the band, and annual merit cycles that compound existing differentials. The audit is most useful when it anchors an annual review cadence.

Remediation budgeting: replacing an employee can cost 50% to 200% of their annual salary, depending on role and seniority (SHRM, 2025). The cost of a targeted pay adjustment to bring an employee above the range minimum is almost always a fraction of the replacement cost if that employee leaves due to perceived inequity. Present this framing to leadership when making the remediation budget case — not as a fear argument, but as a straightforward cost comparison.

The SHRM benchmark cost of hiring a new full-time employee was almost $4,700 (SHRM via NXTThing RPO, 2023), before accounting for lost productivity, training time, and the compounding effect of team disruption in a small organization. A below-minimum salary adjustment is typically a one-time fixed cost. Frame the remediation budget accordingly.

Recommended review triggers (at minimum):

• Annually, after the BLS OEWS new-release cycle (the May 2025 release was published May 15, 2026 — plan your range review for early summer each year)
• After any reorg, job-family restructuring, or significant headcount change
• Before any EEO certification, government contract bid, or investor due-diligence process
• When any pay-transparency law takes effect in a jurisdiction where you have employees (for the current landscape across 16+ states and D.C., see pay equity laws overview)

Putting the Audit Together: Your Next Step

A pay equity audit conducted this way — clean data, BLS-anchored ranges, documented compensable factors, written findings, remediation schedule — is the difference between a defensible compensation program and a spreadsheet with a compliance problem waiting to surface.

The framework above covers the method. The documentation discipline is what makes it work. Our Pay Equity Audit Checklist packages the six steps into a structured, fillable checklist you can hand to your team or your attorney: scoping questions, a range-validation worksheet anchored to BLS OEWS methodology, an outlier-flagging template, a compensable-factor documentation form, and a findings-report outline.

If you want to run the underlying range-building and compa-ratio analysis inside a purpose-built tool rather than a spreadsheet, Salary Range Builder's pricing plans start at $199/mo — a 14-day free trial is included, and the Business plan adds the pay-equity analytics dashboard and range-penetration/compa-ratio reporting that turn the manual steps above into a repeatable, auditable workflow.

A pay equity audit does not have to be a forensic investigation. Run annually, documented consistently, and anchored in public BLS wage data, it is simply good compensation governance — the kind that holds up when the employment attorney asks her Friday afternoon question.
