Class: 11Subject: AccountancyBook: Financial Accounting – IChapter: 2Chapter Name: Theory Base of AccountingSession: 2026–27
Chapter 2, Theory Base of Accounting, builds the conceptual foundation needed before recording transactions. To make accounting information reliable and comparable for both internal and external users, the accounting profession follows a set of rules called Generally Accepted Accounting Principles (GAAP) — also referred to as concepts and conventions. The chapter explains thirteen basic accounting concepts (Business Entity, Money Measurement, Going Concern, Accounting Period, Cost, Dual Aspect, Revenue Recognition, Matching, Full Disclosure, Consistency, Conservatism, Materiality and Objectivity), the two systems of accounting (double entry and single entry), the two bases of accounting (cash basis and accrual basis), the role of Accounting Standards issued by the Institute of Chartered Accountants of India (ICAI), and the structure of Goods and Services Tax (GST) — CGST, SGST and IGST.
Key Terms & Accounting Concepts
GAAP: the rules or guidelines adopted for recording and reporting business transactions, to bring uniformity in the preparation and presentation of financial statements.
Business Entity Concept: the business has a distinct and separate entity from its owners; capital is a liability of the business to the owner and drawings reduce it.
Money Measurement Concept: only transactions and events that can be expressed in money are recorded, and they are recorded in monetary units, not physical units.
Going Concern Concept: the firm is assumed to continue operating indefinitely, which is why the cost of an asset is spread over its useful life rather than charged fully in the year of purchase.
Accounting Period Concept: financial statements are prepared at regular intervals (normally one year) so that timely information is available to users.
Cost Concept: assets are recorded at their purchase price (acquisition + transport + installation, etc.), which is historical and verifiable.
Dual Aspect Concept: every transaction has a two-fold effect and is recorded in at least two accounts — the basis of the double entry system, expressed as the Accounting Equation.
Assets = Liabilities + Capital
Revenue Recognition (Realisation) Concept: revenue is recorded only when it is realised, i.e. when a legal right to receive it arises (e.g. credit sales are revenue on the date of sale).
Matching Concept: expenses of a period are matched with the revenues of the same period to find true profit or loss.
Full Disclosure Concept: all material and relevant facts must be fully and fairly disclosed in the financial statements and their notes.
Consistency Concept: the same accounting policies and methods should be followed from one period to the next so results are comparable.
Conservatism (Prudence) Concept: do not anticipate profits, but provide for all possible losses (e.g. closing stock at cost or market price, whichever is lower).
Materiality Concept: accounting focuses on material facts — those whose knowledge would influence the decision of an informed user.
Objectivity Concept: transactions should be recorded objectively, free from bias, supported by verifiable documents or vouchers.
Accounting Standards: written policy documents on recognition, measurement, presentation and disclosure, issued by the ICAI to bring uniformity and comparability.
GST: a destination-based tax on consumption of goods and services with three components — CGST and SGST on intra-state supply, and IGST on inter-state supply.
“Questions for Practice” — Full Solutions
All questions below are reproduced verbatim from the NCERT textbook’s end-of-chapter Questions for Practice section. Answers are original, written in exam-ready style.
Short Answers
1. Why is it necessary for accountants to assume that business entity will remain a going concern?
ANSWERIt is necessary because the going concern assumption provides the very basis for valuing and recording assets in the balance sheet. If the business is assumed to continue indefinitely, an asset can be treated as a bundle of services to be used over its estimated life.This allows the accountant to charge only that part of an asset which is consumed in earning the revenue of a period (through depreciation) and carry forward the remaining cost to future years. For example, a computer costing ₹ 50,000 with a 5-year life is charged at ₹ 10,000 a year rather than ₹ 50,000 in the year of purchase.Without this assumption, the entire cost of every asset would have to be written off in the year it is bought, which would distort profit and make the accounts meaningless. It also justifies recording prepaid expenses, outstanding items and the classification of assets and liabilities.
2. When should revenue be recognised? Are there exceptions to the general rule?
ANSWERAccording to the revenue recognition (realisation) concept, revenue should be recognised when it is realised — that is, when a legal right to receive it arises, namely the point at which goods are sold or a service is rendered. Thus credit sales are treated as revenue on the date of sale, not when cash is received. Incomes like rent, interest and commission are recognised on a time basis for the period to which they relate.Yes, there are exceptions:(i) In long-term contracts such as construction work that take 2–3 years, a proportionate amount of revenue, based on the part of the contract completed by the end of the period, is treated as realised.(ii) In hire-purchase sales, the amount collected in instalments is treated as realised as and when it is received.
3. What is the basic accounting equation?
ANSWERThe basic accounting equation is the expression of the dual aspect concept, which states that every transaction has a two-fold effect, so the total assets of a business always equal the total claims against them (the claims of owners plus the claims of outsiders).
Assets = Liabilities + Capital
Here Capital (owners’ equity) is the claim of the owner and Liabilities (creditors’ equity) is the claim of outsiders. Every transaction affects the two sides in such a way that the equality is always maintained. This equation forms the core of the double entry system of accounting.
4. The realisation concept determines when goods sent on credit to customers are to be included in the sales figure for the purpose of computing the profit or loss for the accounting period. Which of the following tends to be used in practice to determine when to include a transaction in the sales figure for the period. When the goods have been:
a. dispatched b. invoiced c. delivered d. paid for
Give reasons for your answer.
ANSWEROption (b) — when the goods have been invoiced.Reason: Under the realisation concept, revenue is recognised when a legal right to receive payment arises, i.e. when ownership in the goods passes to the customer. The raising of the invoice is the point at which the sale is treated as complete and the firm acquires the legal right to receive the amount; therefore the transaction is included in the sales figure when the goods are invoiced.It is not recorded merely on dispatch or delivery (the legal sale is evidenced by the invoice), nor is it postponed until the goods are ‘paid for’ — if recognition waited for payment, credit sales would never be recorded as revenue in the period they were made, which would violate the realisation and matching concepts.
5. Complete the following worksheet:
(i) If a firm believes that some of its debtors may ‘default’, it should act on this by making sure that all possible losses are recorded in the books. This is an example of the ___________ concept.
(ii) The fact that a business is separate and distinguishable from its owner is best exemplified by the ___________ concept.
(iii) Everything a firm owns, it also owns out to somebody. This co-incidence is explained by the ___________ concept.
(iv) The ___________ concept states that if straight line method of depreciation is used in one year, then it should also be used in the next year.
(v) A firm may hold stock which is heavily in demand. Consequently, the market value of this stock may be increased. Normal accounting procedure is to ignore this because of the ___________.
(vi) If a firm receives an order for goods, it would not be included in the sales figure owing to the ___________.
(vii) The management of a firm is remarkably incompetent, but the firms accountants can not take this into account while preparing book of accounts because of ___________ concept.
ANSWER
No.

Long Answers
1. ‘The accounting concepts and accounting standards are generally referred to as the essence of financial accounting’. Comment.
ANSWERAccounting concepts and accounting standards together form the foundation on which the entire structure of financial accounting rests, which is why they are called its essence.Accounting concepts are the fundamental assumptions and broad working rules — business entity, money measurement, going concern, accounting period, cost, dual aspect, revenue recognition, matching, full disclosure, consistency, conservatism, materiality and objectivity. They bring uniformity and consistency to the way transactions are identified, measured, recorded and reported, so that the information becomes reliable and comparable for all users.Accounting standards are written policy documents issued by the ICAI covering recognition, measurement, presentation and disclosure. They reduce the scope of alternative accounting treatments, enhance the credibility and comparability of financial statements both within a firm (inter-period) and between firms (inter-firm), and ensure a true and fair view.Because financial statements are the main means of communicating financial information to owners, investors, creditors and the government, they must be prepared on a sound and uniform basis. Concepts supply that theoretical base and standards make its application uniform in practice — hence both are rightly regarded as the essence of financial accounting.
2. Why is it important to adopt a consistent basis for the preparation of financial statements? Explain.
ANSWERIt is important to adopt a consistent basis because the usefulness of accounting information depends on the ability to make meaningful comparisons, and comparisons are valid only when the same policies and methods are applied uniformly.Inter-period comparison: an investor or manager often wants to compare the current year’s performance with previous years. If, say, the method of charging depreciation or valuing stock is changed from one year to the next, the profit figures will not be comparable and any conclusion drawn would be misleading.Inter-firm comparison: comparing the results of two enterprises is meaningful only if both adopt the same kind of accounting methods and policies. Consistency therefore makes results comparable across firms as well.Consistency also eliminates personal bias and gives results that are reliable and comparable. However, consistency does not prohibit a change in accounting policy where a change is genuinely required — but any such change must be fully disclosed in the financial statements along with its probable effect on the results.
3. Discuss the concept-based on the premise ‘do not anticipate profits but provide for all losses’.
ANSWERThe premise ‘do not anticipate profits but provide for all losses’ describes the Conservatism (Prudence) Concept. It provides guidance for recording transactions and is based on the policy of ‘playing safe’.The concept requires that a conscious approach be adopted in ascertaining income so that profits are not overstated. Profits should not be recorded until they are actually realised, whereas all losses — even those that have only a remote possibility — should be provided for in the books.Examples: valuing closing stock at cost or market value, whichever is lower; creating a provision for doubtful debts and discount on debtors; and writing off intangible assets such as goodwill and patents. If the market value of goods falls, stock is shown at the lower value; but if the market value rises, the gain is not recorded until the stock is actually sold.Importance: conservatism is an important way of dealing with uncertainty and protects creditors against an unwanted distribution of the firm’s assets, since overstated profits could lead to dividends being paid out of capital. However, a deliberate attempt to understate the value of assets should be avoided, as it creates hidden profits known as secret reserves.
4. What is matching concept? Why should a business concern follow this concept? Discuss.
ANSWERMeaning: The matching concept states that the expenses incurred in an accounting period should be matched with the revenues earned during that same period. In other words, the revenue and the expenses incurred to earn that revenue must belong to the same accounting period, so that the true profit or loss can be ascertained.Under this concept, revenue is recognised when a sale is complete or a service is rendered (not when cash is received), and an expense is recognised when an asset or service is used to generate revenue (not when cash is paid). Thus salaries, rent and insurance are recognised on the basis of the period to which they relate, and the cost of a fixed asset is spread over its useful life as depreciation. To match cost of goods sold with sales, the cost of unsold (closing) stock is deducted from the cost of goods produced or purchased.Why a business should follow it: Profit or loss can be measured correctly only when expenses are properly set against the revenues they help to earn. Following the matching concept ensures that all revenues earned during a year (whether received or not) and all costs incurred during that year (whether paid or not) are taken into account, so the profit and loss account shows a true and fair result for the period. Ignoring it would distort profit by mixing items of different periods.
5. What is the money measurement concept? Which one factor can make it difficult to compare the monetary values of one year with the monetary values of another year?
ANSWERMoney measurement concept: Only those transactions and happenings of an organisation which can be expressed in terms of money — such as the sale of goods, payment of expenses or receipt of income — are recorded in the books of account. Events that cannot be measured in money, like the appointment of a manager, the skills of employees, the creativity of the research team or the firm’s reputation, are not recorded. Moreover, records are kept in monetary units, not in physical units, so that different assets (land, buildings, computers, raw material, etc.) can be added together and expressed as one total worth of the business.The factor that makes comparison difficult — the changing value of money: Because of changes in prices, the value of money does not remain the same over time. Due to a rise in prices, a rupee today buys much less than it did, say, ten years ago. When assets bought at different times are added in the balance sheet — for example a building bought in 1995 for ₹ 2 crore and a plant bought in 2005 for ₹ 1 crore — we are in fact adding heterogeneous (unequal) values. Since this change in the value of money is not reflected in the books, the accounting data does not show the true and fair position, and the monetary values of one year cannot be reliably compared with those of another year.
Extra Practice Questions
Short Answer Type Questions
Q1. What is meant by GAAP?
ANSWERGenerally Accepted Accounting Principles (GAAP) are the rules or guidelines, evolved over time and accepted by the accounting profession, that are adopted for recording and reporting business transactions in order to bring uniformity in the preparation and presentation of financial statements. They are also called concepts and conventions.
Q2. Distinguish between the cash basis and accrual basis of accounting.
ANSWERUnder the cash basis, entries are made only when cash is actually received or paid, irrespective of the period to which they relate; it ignores the matching principle. Under the accrual basis, revenues and costs are recognised in the period in which they occur (when earned or incurred), regardless of when cash is received or paid. The accrual basis is more appropriate as it correctly matches expenses with the revenues they earn.
Q3. State two benefits of Accounting Standards.
ANSWER(i) They eliminate variations in accounting treatment and bring uniformity in the preparation of financial statements. (ii) They enhance the comparability of financial statements between different companies (inter-firm) and over different periods of the same company (intra-firm). They may also require disclosures useful to investors and creditors that the law does not demand.
Q4. What is the dual aspect of GST? Name its three components.
ANSWERGST has a dual aspect because both the Centre and the States simultaneously levy tax on a common tax base. Its three components are CGST (Central GST, collected by the Centre on intra-state supply), SGST (State GST, collected by the State on intra-state supply) and IGST (Integrated GST, levied by the Centre on inter-state supply and imports, then shared with the States).
Q5. Why is the objectivity concept important in accounting?
ANSWERThe objectivity concept requires that transactions be recorded objectively, free from the personal bias of the accountant, and supported by verifiable documents such as cash receipts, invoices and vouchers. It makes the accounts reliable and verifiable and is one of the main reasons for adopting historical cost, since the cost actually paid can be proved from documents whereas market value cannot.
Long Answer Type Questions
Q1. Explain the two systems of accounting.
ANSWERThere are two systems of recording transactions. The double entry system is based on the dual aspect principle — every transaction has two effects, the receiving of a benefit and the giving of a benefit — so each transaction is recorded in at least two accounts, with every debit having a corresponding credit. It is a complete, accurate and reliable system because both aspects of a transaction are recorded, arithmetical accuracy can be checked through the trial balance, and frauds are minimised; it suits both large and small organisations. The single entry system is not a complete system: it does not record the two-fold effect of every transaction. Only personal accounts and the cash book are usually maintained; for some transactions only one aspect is recorded and for others both. The records are incomplete, unsystematic and unreliable, but the system is sometimes followed by very small firms because it is simple and flexible.
Q2. Explain the cost concept and state its main limitation.
ANSWERThe cost concept requires that all assets be recorded in the books at their purchase price, which includes the cost of acquisition plus expenses on transportation, repairs needed to make the asset usable, and installation. For example, if a plant is bought for ₹ 50 lakh and ₹ 10,000 is spent on transport, ₹ 15,000 on repairs and ₹ 25,000 on installation, it is recorded at ₹ 50,50,000. The cost is historical — it is what was actually paid on the date of acquisition and does not change year after year even if the market value changes. Its great advantage is objectivity, because the cost can be verified from purchase documents, which makes the records reliable and comparable. Its main limitation is that historical cost does not show the true present worth of the business: during a period of rising prices the market or replacement value of assets is higher than the recorded value, which can lead to hidden profits and an understatement of the firm’s real position.
Q3. Discuss the need for and limitations of Accounting Standards.
ANSWERNeed: Accounting serves many different users, and its information is useful only if it has uniformity and full disclosure of relevant facts. Because several alternative accounting treatments and valuation methods exist, different firms could record similar transactions differently, making their statements non-comparable. Accounting Standards, issued by the ICAI, narrow down these alternatives to those that meet the qualitative characteristics of a true and fair statement, thereby bringing uniformity, improving the credibility of accounting data and enhancing the comparability of financial statements both within and between enterprises. Limitations: (i) The choice between different alternative treatments permitted by a standard can still be difficult to apply. (ii) Standards are sometimes rigidly followed and may fail to give the flexibility needed in particular situations. (iii) Accounting Standards cannot override the statute — they must be framed within the limits of prevailing laws, customs and the business environment, so where a law conflicts with a standard, the law prevails.

Exam Tips & Common Mistakes
How to score full marks in this chapter
Learn all thirteen accounting concepts with one short example each — the ‘fill in the concept’ style of question (Short Answer 5) is very common. Remember the accounting equation Assets = Liabilities + Capital and link it to the dual aspect concept. Be able to clearly distinguish the two systems (double vs single entry) and the two bases (cash vs accrual) of accounting, since these are frequent long-answer questions. For GST, memorise that CGST and SGST apply to intra-state supply while IGST applies to inter-state supply, and that Accounting Standards are issued by the ICAI. Always justify the concept you name with a one-line reason — the reasoning fetches the marks.
Common mistakes to avoid
Confusing the realisation concept (recording revenue when sold/invoiced) with recording it only when cash is received.
Mixing up consistency (same method over time) with conservatism (provide for losses, ignore unrealised gains).
Writing the accounting equation wrongly — it is Assets = Liabilities + Capital, not Capital = Assets + Liabilities.
Saying Accounting Standards can override the law — they must stay within the prevailing statute.
Forgetting that under the matching concept, costs and revenues count whether or not cash has changed hands.
Treating the owner’s personal transactions as the business’s — this violates the business entity concept.
Frequently Asked Questions
What is Chapter 2 of Class 11 Accountancy about?
Chapter 2, Theory Base of Accounting, explains the conceptual foundation of accounting — Generally Accepted Accounting Principles (GAAP), the thirteen basic accounting concepts, the systems of accounting (double and single entry), the bases of accounting (cash and accrual), Accounting Standards issued by the ICAI, and the structure of GST.
