Theory Base of Accounting — Class 11 (Accountancy)
If every accountant recorded things their own way, no two sets of accounts could be compared or trusted. So accounting follows a shared rulebook — GAAP — a set of concepts and conventions everyone agrees to use. This chapter is that rulebook, and it explains why transactions are recorded the way they are.
1. GAAP and the need for principles
GAAP (Generally Accepted Accounting Principles) are the common rules and guidelines that make financial statements reliable, uniform and comparable. They evolved from practice and are backed by accounting standards.
2. Fundamental accounting concepts
- Business Entity — the business is treated as separate from its owner; only business transactions are recorded (owner's private expenses are drawings).
- Money Measurement — only transactions measurable in money are recorded (loyalty of staff, though valuable, is not).
- Going Concern — the business is assumed to continue indefinitely; hence assets are recorded at cost and depreciated over life, not at sale value.
- Accounting Period — accounts are prepared for a fixed period (usually one year) so performance can be measured regularly.
- Cost Concept — assets are recorded at their acquisition (historical) cost, not market value.
- Dual Aspect — every transaction has two aspects (debit and credit); the basis of double entry: Assets = Liabilities + Capital.
- Revenue Recognition (Realisation) — revenue is recorded when it is earned/realised, not necessarily when cash is received.
- Matching — expenses are matched with the revenues of the same period to find correct profit.
- Full Disclosure — all significant information must be disclosed in the statements.
- Consistency — the same methods are followed period after period (so results are comparable).
- Conservatism (Prudence) — anticipate no profit but provide for all possible losses (e.g. provision for doubtful debts).
- Materiality — only items significant enough to affect decisions need detailed treatment.
- Objectivity — entries should be based on verifiable evidence (vouchers, bills).
3. Bases of accounting
- Cash basis — records transactions only when cash is received or paid. Simple, but ignores outstanding items.
- Accrual (mercantile) basis — records revenues when earned and expenses when incurred, regardless of cash. This is the standard basis (follows matching and revenue-recognition concepts) and gives a true profit.
4. Accounting standards and IFRS
- Accounting Standards (AS) — written policy documents issued (in India by the ICAI) to standardise treatment and improve comparability.
- IFRS (International Financial Reporting Standards) — global standards for uniform, comparable reporting across countries; India has converged standards (Ind AS).
Standards reduce accounting alternatives, improving reliability and comparability.
5. Goods and Services Tax (GST)
GST is a single, comprehensive indirect tax on the supply of goods and services, which replaced many earlier taxes. It is destination-based and levied at each stage with credit for tax paid on inputs (input tax credit), avoiding tax-on-tax (cascading). Accounting must record GST (CGST, SGST, IGST) on purchases and sales.
6. Closing thought
The theory base — GAAP concepts, the accrual basis, accounting standards/IFRS and GST — is why accounting produces trustworthy, comparable statements. Learn each concept with a one-line reason and example (business entity, going concern, matching, prudence, dual aspect). In the board exam this chapter reliably gives "identify/explain the concept" and cash-vs-accrual questions worth 4–6 marks.
