Salary Structure Design That Survives a Labour Inspection

A salary structure that looks fine on paper can still fail a labour inspection if the underlying wage base is wrong for PF, ESI, gratuity or minimum wages. Here is what a defensible structure actually needs.

Key facts at a glance

• Basic pay plus DA must be at least 50% of total remuneration under the Code on Wages.
• PF applies to basic + DA up to a Rs 15,000/month ceiling, at 12% employee + 12% employer.
• ESI applies to gross wages up to Rs 21,000/month, at 0.75% employee + 3.25% employer.
• Minimum wages are set state-by-state and vary by skill category and sometimes by industry.
• Under-contribution discovered on inspection can mean arrears plus interest and damages, not just the shortfall itself.
• All four Labour Codes are in force nationally since 21 November 2025, but state rules are still being notified unevenly as of mid-2026.

What Inspectors Actually Look For

A labour inspection is rarely a surprise checklist - it typically follows a predictable sequence:

1. Minimum wage compliance - is basic pay, or the relevant wage component, at or above the state-notified minimum wage for that category of worker?
2. PF and ESI wage base - are contributions calculated on the correct components, at the correct rate, up to the correct ceiling?
3. Statutory registers and records - wage registers, attendance records, appointment letters, and challans for PF/ESI deposits.
4. Structure design itself - whether allowances have been used to artificially depress the wage base used for statutory calculations.

Getting the Wage Base Right

The most common structural weakness inspectors find is a basic pay set too low relative to total compensation, specifically to reduce PF and gratuity contributions. The Code on Wages now directly addresses this: basic pay plus DA must equal at least 50% of total remuneration, and any shortfall is added back to the wage base for statutory calculation purposes regardless of how the rest of the pay is labelled.

This means a structure that was technically compliant under the old wage definitions can now fail, purely because the proportion of basic pay is too low. Reviewing this ratio should be the first step in any structure audit.

Minimum Wages Are Set State by State

Unlike PF and ESI, which are centrally administered with fixed ceilings, minimum wages are notified separately by each state government, and often vary further by skill category (unskilled, semi-skilled, skilled, highly skilled) and sometimes by industry or zone within the state. A structure that is compliant in one state can fall short in another for an identical role and pay level. Employers with multi-state operations need to check the applicable notification in every state where they employ staff, not assume a single national figure applies.

Documentation That Backs Up Your Structure

A defensible salary structure is only as good as the paperwork behind it. Inspectors will typically expect to see:

• Appointment letters specifying the salary breakup for each employee.
• Wage registers and salary slips showing consistent application of the structure.
• Attendance records that reconcile with wage payments.
• PF and ESI challans showing timely deposit at the correct rate and base.
• Minimum wage notifications for the relevant state, industry and skill category, kept on file for reference.

Missing documentation can turn an otherwise compliant structure into a liability during an inspection, simply because the employer cannot demonstrate compliance on the spot.

Steps to Audit-Proof Your Salary Structure

1. Calculate the basic + DA ratio for every pay band and confirm it meets the 50% threshold.
2. Cross-check basic pay against the applicable state minimum wage for each employee category.
3. Verify PF and ESI are calculated on the correct base and ceiling, not on a reduced or incorrect figure.
4. Recalculate gratuity and bonus bases if you adjust basic pay upward to meet the 50% rule.
5. Keep statutory registers and challans current and accessible, not just filed away after the fact.
6. Review annually, and whenever minimum wage notifications or Labour Code rules change in your state.
