Definition of Chart of Accounts
A chart of accounts is a hierarchical arrangement of financial accounts used in an accounting system. It is considered an organizational structure that provides a comprehensive view of the various financial accounts used in an institution or company.
Method of Preparing Chart of Accounts
Preparing a chart of accounts is a systematic process that requires careful planning and deep understanding of the business nature and its accounting requirements. The process begins by identifying the main account categories which include assets, liabilities, equity, revenues, and expenses, as these categories form the foundation upon which the accounting structure of the organization is built.
After identifying the main categories, each category is divided into more detailed subcategories to facilitate classification and monitoring. For example, assets can be divided into fixed assets and current assets, while expenses can be divided into operating expenses and administrative expenses. This division helps obtain a clearer view of the financial position and performance of the organization.
In the final stage of preparation, detailed accounts are created under each subcategory, which represent specific elements such as cash in banks, inventory, and machinery and equipment. These detailed accounts are what receive actual accounting transactions and provide the accurate data necessary for preparing financial reports.
Companies usually adopt account numbering as follows:
- Assets: (1)
- Liabilities: (2)
- Equity: (3)
- Revenues: (4)
- Expenses: (5)
Under each main account, its sub-accounts are listed. Illustrative examples:
Illustrative Example (1): Company Cash Accounts to the Third Level
- 1 Assets
- 11 Current Assets
- 1120 Cash
- 11201 Main Bank Account
- 11202 Secondary Bank Account
- 11203 Cash Box
- 1120 Cash
- 11 Current Assets
Illustrative Example (2): Fixed Assets Accounts to the Second Level
- 1 Assets
- 12 Fixed Assets
- 1201 Office Furniture
- 1202 Equipment and Machinery
- 12 Fixed Assets
Illustrative Example (3): Revenue Account for Company's Main Branch to the Second Level
- 4 Revenues
- 41 Main Branch Revenues
- 4101 Service Revenues
- 4102 Product Sales Revenues
- 4103 Other Revenues
- 41 Main Branch Revenues
General Note: No transactions can be entered into main accounts because they are summary accounts for last-level accounts. For clarification, as in example (1), accounts numbered 1, 11, 1120 are all main summary accounts. However, accounts 11201, 11202, 11203 are non-main accounts that accept transactions because they are non-summary accounts.
Basic Accounts
The classifications and size of chart of accounts vary according to each organization, but all organizations share 5 main accounts:
- Assets - All resources owned by the company
- Liabilities - All debts and financial obligations
- Equity - Capital and shareholders' rights
- Revenues - All income and returns
- Expenses - All costs and expenditures
