How to Read Your Monthly Payroll Report — Without Missing Anomalies

Zaffre HRM Team · May 30, 2026

Most CFOs glance at the monthly payroll total, compare it to last month, and move on. The report has more to say — anomalies, trends, statutory contribution pressures, employee-level surprises that point to process issues. Here is how to read a monthly payroll report properly.

The 6 things to check in every monthly payroll

1. Headcount reconciliation

Number of payslips generated vs number of active employees at month-end. If they disagree, investigate:

  • Resigned employees still in payroll (terminate them)
  • New joiners missing payslip (mid-month proration issue)
  • Hold-status employees expected to be released

2. Total payroll cost vs trend

Plot last 6 months. Sudden jumps (+5% or more) without obvious cause (raises, hiring) → investigate.

  • One-time bonuses paid?
  • Arrears for a backdated revision?
  • Significant overtime spike?
  • EOBI / PESSI rate change?

3. Statutory contributions reconciliation

  • EOBI — total employer + employee contributions vs registered employees × contribution rate
  • Provincial SS (PESSI / SESSI / etc.) — total vs registered × rate
  • WHT — total withheld vs expected based on tax slabs
  • Professional tax (where applicable)

Discrepancies suggest configuration errors or missed employees.

4. Overtime distribution

Plot overtime cost by department. Outliers (one department running 3x average overtime) → either bad scheduling, understaffing, or overtime abuse. Investigate.

5. Leave deduction reconciliation

Unpaid leaves taken this month × per-day rate = expected deduction total. Reconcile with actual deductions on payslips. Mismatch → investigate.

6. Loan / advance balances

Outstanding loan / advance balance per employee, expected deduction this month, actual deducted, new outstanding. Track to ensure recovery is on schedule.

The 8 anomalies a good payroll report flags automatically

1. Salary above expected range

An employee whose net pay is significantly higher than last month (and not due to a known increment) → check for arrears, bonus, allowance addition that may have been entered wrong.

2. Salary below expected range

Significant drop → check for unpaid leave, large deduction, withholding tax bump.

3. Negative net pay

Deductions exceeding earnings — rare but possible for an employee in heavy loan recovery. Hold the payslip, review.

4. Zero pay

Either full month unpaid leave (legitimate) or processing error (illegitimate). Verify.

5. Missing payslip for active employee

Did they get filtered out? Check active status, attendance source, payroll inclusion criteria.

6. Payslip for resigned employee

If an employee resigned and is on final settlement, they should not appear in regular payroll. If they do, the resignation status was not processed in time.

7. WHT spike for individual employees

An employee whose tax deduction jumped significantly — usually a year-end catch-up. Should be expected; flag if not.

8. Loan recovery completion

Employee finished paying off a loan this month — next month their net pay will be higher. Communicate proactively.

The monthly review meeting

HR + finance + (optionally) operations should run a 30-minute monthly payroll review:

  • Total cost vs trend
  • Headcount reconciliation
  • Statutory contributions reconciliation
  • Overtime by department
  • Anomalies flagged
  • Resolutions documented

Skipping this is how the company drifts into compliance issues that surface only at audit.

The year-end view

Aggregate the monthly data:

  • Total annual payroll cost vs budget
  • Department-wise totals
  • Overtime as % of payroll (should be tracked over time)
  • Statutory contributions paid for tax filing
  • Per-employee year-end salary tax certificates

What HR / payroll software must provide

  • Monthly summary dashboard (cost, headcount, trends)
  • Anomaly detection automated
  • Statutory reconciliation views
  • Department / location drill-downs
  • Year-on-year + month-on-month comparisons
  • Per-employee history and projections
  • Export to accounting / general ledger formats
