Definition
The chart of accounts assigns each ledger account a number, name and type: asset, liability, equity, revenue or expense. Most charts group accounts in number ranges so they map to statement captions. No accounting standard prescribes the chart. Entities design it to support their reporting, tax and management needs, and a well-built chart keeps similar items together and separates restricted, related-party and intercompany balances.
Why it matters in an audit or review
The auditor builds lead schedules and the trial balance from the chart, so unmapped or mis-mapped accounts can leave amounts out of the statements. New accounts, accounts renamed during the year, and large balances in catch-all accounts such as miscellaneous or suspense are examined. Understanding the chart is part of understanding the entity's information system under AU-C 315.
Example
Illustrative: accounts 1000 to 1999 are assets, 2000 to 2999 liabilities, 3000 to 3999 equity, 4000 to 4999 revenue and 5000 to 7999 expenses. A new account 1850 for a deposit is created in December but not mapped to any caption, so $45,000 is missing from the draft balance sheet until the trial balance is tied to the statements.
Common mistakes
- Creating accounts mid-year without updating the statement mapping.
- Using the same account for different purposes across periods.
