37. P&L Review — Red Flags & Trends

The Profit & Loss Account is the first document scrutinised by auditors, tax officers, banks, and investors.However, most issues in P&L do not arise from law — they arise from patterns, inconsistencies, and trends.
This guide explains how to review a P&L statement critically, identify red flags, and analyse trends that may lead to notices, audit queries, or wrong business decisions.

1. Introduction — Why P&L Review Matters

A P&L shows:
  • Profitability of operations
  • Cost structure
  • Efficiency of management
  • Tax exposure
Weak P&L review leads to:
  • Inflated or suppressed profits
  • Disallowance of expenses
  • GST and TDS scrutiny
  • Misleading MIS
  • Poor pricing and cost decisions
A clean P&L is not one that shows profit — it is one that can be logically explained and defended.

2. Objective

To provide a structured framework to:
  • Analyse income and expense trends
  • Identify red flags and anomalies
  • Detect accounting and compliance issues
  • Link P&L with balance sheet and cash flow
before audit, return filing, or assessment.

3. What Is P&L Review?

P&L review is an analytical and logical examination of:
  • Income streams
  • Cost behaviour
  • Margin movement
  • Year-on-year and month-on-month trends
It answers questions like:
  • Does this profit make sense?
  • Are expenses proportionate to revenue?
  • Is there any abnormal spike or dip?

4. CABTA Framework — “The 8-Layer P&L Review Model”

Layer 1 — Revenue Consistency & Recognition Test

Review:
  • Total revenue vs prior year
  • Monthly/quarterly revenue pattern
  • Sudden year-end revenue spikes
  • Revenue booked without corresponding receivables or cash
Triangular Flag Red Flags
  • Large March sales
  • Revenue without invoices
  • Netting off of expenses from revenue
  • Revenue growth without capacity increase
Warning Risk: Bogus sales, GST mismatch, income suppression allegations

Layer 2 — Gross Profit (GP) Trend Analysis

Analyse:
  • GP % current year vs previous years
  • GP by product / service
  • GP movement vs purchase cost
Triangular Flag Red Flags
  • Sharp fall or rise in GP without explanation
  • Negative GP
  • GP inconsistent with industry norms
Warning Risk: Rejection of books, estimated profit addition

Layer 3 — Expense-to-Revenue Ratio Test

Compare:
  • Total expenses as % of turnover
  • Major expense heads vs revenue growth
Triangular Flag Red Flags
  • Expenses rising faster than revenue
  • High expenses with stagnant turnover
  • Flat expenses despite high growth
Warning Risk: Disallowance, inflated expense suspicion

Layer 4 — Fixed vs Variable Cost Behaviour

Identify:
  • Fixed costs (rent, salaries, admin)
  • Variable costs (raw material, logistics, commissions)
Check:
  • Whether fixed costs behave abnormally
  • Whether variable costs scale with revenue
Triangular Flag Red Flags
  • Fixed costs jumping suddenly
  • Variable costs not moving with sales
Warning Risk: Wrong classification, margin distortion

Layer 5 — High-Risk Expense Ledger Scan

Mandatory scrutiny of:
  • Professional fees
  • Commission & brokerage
  • Repairs & maintenance
  • Advertisement & marketing
  • Business promotion
  • Travelling & conveyance
  • Miscellaneous expenses
Triangular Flag Red Flags
  • Round-figure expenses
  • Cash-heavy expenses
  • No TDS where applicable
  • Personal elements mixed
Warning Risk: Disallowance u/s 37, 40(a)(ia), cash additions

Layer 6 — Month-End & Year-End Adjustment Test

Review:
  • Large journal entries in March
  • Bulk expense booking at year-end
  • Provisions without basis
  • One-time adjustments
Triangular Flag Red Flags
  • “Plug” entries to manage profit
  • Provisions without working
  • Reversals missing next year
Warning Risk: Audit qualification, tax disputes

Layer 7 — Tax Alignment Test (GST / TDS / IT)

From P&L, verify:
GST
  • Output GST not part of revenue
  • GST expense limited to interest/penalty
  • ITC not routed through P&L
TDS
  • TDS-attracting expenses identified
  • No expense net of TDS
Triangular Flag Red Flags
  • GST booked as expense
  • TDS shown as expense
  • Professional fees without TDS
Warning Risk: Notices, disallowances, penalties

Layer 8 — Exceptional / Non-Recurring Items Review

Identify:
  • One-time income
  • One-time expenses
  • Prior period items
Ensure:
  • Separate disclosure
  • Proper explanation
Triangular Flag Red Flags
  • Recurring “one-time” expenses
  • Prior period items adjusted silently
Warning Risk: Profit manipulation allegations

5. Trend Analysis — What to Compare

A good P&L review compares:
  • Current year vs last 2–3 years
  • Monthly trend (especially Q4 vs Q1–Q3)
  • Expense head vs turnover
  • Margins vs industry benchmarks
Trends tell more than totals.

6. Common P&L Red Flags in SMEs

  • High miscellaneous expenses
  • Sharp GP fluctuation
  • Cash expenses without logic
  • Professional fees without TDS
  • Marketing expense spike before year-end
  • No depreciation or abnormal depreciation
  • Profit inconsistent with cash flow
  • Loss year followed by high profit without explanation

7. Linkage Checks (Critical)

Always link P&L with:
  • Balance Sheet:– Profit vs reserve movement– Expenses vs advances/provisions
  • Cash Flow:– Profit vs operating cash flow
Mismatch indicates accounting or timing issues.

8. Case Example — Preventing Estimated Profit Addition

Issue:GP dropped from 18% to 9% without explanation.

9. P&L Review vs TB & BS Review

Review Type
Primary Focus
Trial Balance
Structural correctness
P&L Review
Profit logic & trends
Balance Sheet
Risk & sustainability
All three together create defensible financials.

“A P&L does not fail because of numbers — it fails because of unexplained behaviour.”
