An income statement — known in India as the Statement of Profit and Loss, or simply the P&L account — is one of the three core financial statements, alongside the balance sheet and the cash flow statement. It reports business performance over a period (a quarter or a full financial year), showing how revenue is converted into profit after every cost. This is what separates it from the balance sheet, which captures your financial position on a single date.
Format under the Companies Act, 2013
Companies must prepare the Statement of Profit and Loss in the format prescribed by Schedule III of the Companies Act, 2013. Division I applies to companies on Accounting Standards (AS), Division II to those on Indian Accounting Standards (Ind AS), and Division III to NBFCs. Section 129 requires the statement to give a "true and fair view" and comply with the notified accounting standards. Under Schedule III, income and expenses are grouped as:
- Revenue from operations (shown net of GST, sales returns and discounts) plus other income
- Cost of materials consumed and purchases of stock-in-trade
- Changes in inventories of finished goods and work-in-progress
- Employee benefits expense
- Finance costs (interest)
- Depreciation and amortisation expense
- Other expenses (rent, utilities, professional fees and so on)
Reading the profit ladder
The statement steps down from the top line (revenue) to the bottom line (net profit) through several profitability markers, each answering a different question about the business.
| Metric | How it is derived | What it tells you |
|---|---|---|
| Gross Profit | Net Revenue − COGS | Efficiency of core production or trading |
| EBITDA | Gross Profit − operating expenses (before depreciation) | Operating cash profit |
| Operating Profit (EBIT) | EBITDA − depreciation & amortisation | Profit from core operations |
| Profit Before Tax (PBT) | EBIT − finance costs | Profit after interest, before tax |
| Net Profit (PAT) | PBT − tax expense | The bottom line available to owners |
Filing and compliance obligations
Every company must file its Statement of Profit and Loss with the Registrar of Companies (ROC) as part of its financial statements in Form AOC-4, within 30 days of the Annual General Meeting under Section 137. The same figures flow into the income-tax return — ITR-6 for companies, and ITR-3 or ITR-5 for proprietors, firms and LLPs — for the relevant assessment year. Listed companies must additionally publish quarterly results within 45 days of each quarter end under Regulation 33 of the SEBI (LODR) Regulations, 2015. Quarterly preparation is therefore a listing requirement; an unlisted private company reports annually.
Common mistakes to avoid
- Booking GST collected as revenue — GST is a pass-through liability, not income.
- Mixing capital items (asset purchases) with revenue expenses — capital expenditure sits on the balance sheet and is charged over time through depreciation.
- Ignoring accrual accounting — income and expenses are recognised when earned or incurred, not when cash moves (Section 128 read with the applicable standards).
- Omitting non-cash charges such as depreciation, which understates real cost and overstates profit.
A well-prepared P&L is more than a compliance formality. It is the basis for the profitability ratios — gross margin, operating margin and net margin — that lenders, investors and your own board rely on to judge the health of the business.
