Most pay equity conversations in 2026 have shifted to remote and distributed teams, but the older, still-underserved question sits inside a single office: are the Senior Software Engineers in your Dublin team, all doing genuinely comparable work, paid within a defensible range of each other, and can you show why the ones outside that range are outside it? PayMetric Labs' own benchmark puts the Ireland office band for that level at €85-115k. An internal audit is what tells you whether your actual team's pay sits inside that band coherently, or is quietly compressed, dispersed, or drifting toward an unexplained gap that a formal pay assessment would flag.

This is deliberately about in-country, office-based gross salary equity, not the net take-home tax divergence that dominates remote-team pay equity discussions. If you are auditing a distributed team spread across multiple countries and want to know whether their net take-home is fair given very different tax systems, that is a different question with a different methodology, covered in our companion guide on auditing pay equity on a remote team spread across the UK, Ireland, Singapore, and Dubai. This article covers the in-country office audit.

In-country vs cross-border pay equity: key differences

In-country office audit (this article)

✓Compares gross salary within one national market

✓Uses compa-ratio against a local benchmarked band

✓Driver of unexplained gaps: tenure, performance, level scope

✓Governed by EU Directive gender pay gap reporting where applicable

Remote/distributed team audit (companion guide)

✓Compares net take-home across different countries

✓Same gross-equivalent offer, wildly different tax outcomes

✓Driver of gaps: each country's own tax and social security system

✓See: auditing pay equity on a remote team (UK, Ireland, Singapore, Dubai)

For auditing pay equity across a distributed remote team's net take-home rather than in-country offices' gross bands, see our remote pay equity audit guide.

Identifying salary compression and unexplained wage gaps

Salary compression is the more common finding in most internal audits. It occurs when a long-tenured, strong-performing employee is paid close to, or even below, a newer hire brought in at current market rates. PayMetric Labs' own salary band generator flags compression when more than roughly 40% of a level's employees cluster within 5% of the band midpoint, since that pattern usually means annual reviews have not kept pace with market movement rather than that everyone is genuinely at the same performance level.

An unexplained wage gap is a stricter, legally consequential finding: a pay difference at the same level that survives adjustment for objective, gender-neutral factors like tenure and performance. Under the EU Pay Transparency Directive (2023/970), due for transposition into national law across the EU by 7 June 2026, an employer whose reported gender pay gap exceeds 5% and cannot explain the gap using objective criteria is required to conduct a formal joint pay assessment with worker representatives. This is a directive-specific reporting threshold for gender pay gap disclosure, not a general-purpose rule for every kind of internal audit, but it is a useful benchmark for how strict a genuinely "unexplained" gap needs to be treated.

Using PayMetric Labs' benchmarked bands as a reference point: for Mid-level Software Engineers in Ireland, the market range is €58-82k. If two Mid-level engineers with comparable tenure and performance history sit at opposite ends of that range with no scope difference between their roles, that is exactly the pattern an internal audit is designed to surface before it becomes a formal compliance issue.

5-step internal audit methodology

Group by role and level, not job title

Use a consistent job architecture (scope of impact, decision authority, typical years of experience) to group employees, since titles alone are inconsistently applied across teams and hiring managers.

Calculate each employee's compa-ratio

Divide actual salary by the current market-benchmarked midpoint for that level and location. A ratio of 1.00 sits exactly at midpoint; below 0.80 or above 1.20 signals the person is effectively outside the band entirely.

Flag the outliers

Below-floor employees carry the highest compliance risk. Above-ceiling employees usually mean the band itself needs rebasing against current market data, not that the individual is overpaid. Compressed clusters near the midpoint flag a systemic review-cycle problem.

Test for correlation with protected characteristics

Cross-reference the flagged pattern against gender and other protected characteristics available in your HR data. A pattern that correlates strongly is the specific signal the EU Directive's joint pay assessment obligation is designed to catch once it exceeds the 5% unexplained threshold.

Build a remediation plan, not a one-off fix

Target genuine gaps for the next scheduled review cycle rather than immediate off-cycle adjustments, unless severity warrants faster action. Document the rationale for every remediation decision; that documentation is what makes the band defensible under both EU and any applicable US state disclosure rules.

Remediation tactics without disruption

Fixing every flagged gap immediately and off-cycle is rarely necessary and can create its own equity problem, employees who happened to be audited first getting adjustments that others waiting for the next cycle do not. A tiered approach works better: severe below-floor cases (typically compa-ratio under 0.80) get prioritised for the nearest possible adjustment window; moderate compression gets folded into the next scheduled review cycle with an explicit note on the rationale; above-ceiling cases usually mean the band needs rebasing against current market data rather than the individual needing a pay cut, which is never the right remediation.

Communicate the process, not necessarily the individual findings. Employees are increasingly entitled under 2026's disclosure rules to ask how their pay compares to others in equivalent roles, but a documented, consistently applied audit methodology, run on a known cadence, is what makes that conversation defensible rather than defensive.

Frequently asked questions

What is the difference between an in-country pay equity audit and a remote/distributed team pay equity audit?

An in-country audit compares gross salary dispersion among employees working the same role and level inside the same national office or market, for example every Senior Software Engineer in your Dublin office against each other and against the published market band. A remote or distributed team audit compares net take-home pay across employees based in different countries entirely, where the real driver of pay difference is often tax treatment and currency, not the underlying gross offer. The two audits ask different questions and need different data: in-country audits use gross salary and compa-ratio against a local band, while distributed-team audits use net pay after each country's own tax system. For the distributed, cross-border, net-take-home version of this analysis, see our companion guide, auditing pay equity on a remote team spread across the UK, Ireland, Singapore, and Dubai.

What is salary compression and how do you spot it in an internal audit?

Salary compression happens when employees at meaningfully different tenure or performance levels within the same role and level are paid too similarly, typically because new hires are brought in near current market rates while existing staff's pay has lagged behind annual market movement. In a compa-ratio-based audit, compression shows up as an unusually large share of employees clustered within a narrow band around the midpoint, commonly flagged when more than roughly 40% of a level's employees sit within 5% of the band midpoint, a threshold used by PayMetric Labs' own salary band generator tool. It is one of the most common and most fixable pay equity issues, and it disproportionately affects long-tenured employees who did not job-hop to reset their market rate.

How is an unexplained pay gap defined in a pay equity audit?

An unexplained pay gap is the portion of a pay difference between employees at the same level that remains after accounting for legitimate, objective, gender-neutral factors: tenure at level, performance rating history, scope differences within the level, and location-specific market adjustments. The EU Pay Transparency Directive (2023/970) requires a formal joint pay assessment when an employer's reported gender pay gap exceeds 5% and cannot be explained by such objective criteria. This 5% figure is a specific directive threshold for the gender pay gap reporting obligation, not a general audit rule of thumb for every kind of pay difference, so treat it as directive-specific rather than a universal audit trigger.

How often should an internal pay equity audit be run?

At minimum annually for employers of any meaningful size, and more frequently around major compensation events: after an annual review cycle, after a period of active hiring at a given level, or ahead of a planned band recalibration. Employers with 100 or more employees in the EU will additionally need to run a formal joint pay assessment on a cycle set by the Directive's reporting size tiers once national transposition takes effect (150-249 employees on a triennial cycle with first reporting due by 7 June 2027, 100-149 employees also triennial but with first reporting due later, by 7 June 2031, and 250+ employees annually from 7 June 2027), but an internal audit run more frequently and informally is good practice regardless of whether the formal regulatory trigger applies to your organisation.

What is a 5-step methodology for auditing internal pay equity?

A practical sequence most HR teams can run without external consultants: (1) group employees by role and level using a consistent job architecture, not job title alone; (2) calculate each employee's compa-ratio against the current market-benchmarked band midpoint for their level and location; (3) flag employees below the band floor, above the ceiling, or compressed near the midpoint; (4) test whether any pattern in the flags correlates with a protected characteristic rather than objective factors like tenure or performance; (5) build a remediation plan targeting the next review cycle for genuine gaps, prioritised by severity, rather than making disruptive off-cycle changes across the board.

Can you compare gross salaries directly across countries in a pay equity audit?

Only within the same country's audit, not across countries directly. A Senior Software Engineer earning the top of Ireland's benchmarked range and one earning the top of the UK's benchmarked range are not meaningfully comparable by converting currency, because the two are separate local labour markets with different cost structures, tax systems, and competitive dynamics. Cross-country pay equity questions (is this remote team being treated fairly relative to each other) need a net-take-home, tax-adjusted comparison instead of a gross one; that is a fundamentally different audit, covered in our remote team pay equity guide, not this in-country methodology.
