Chart of accounts definition

What is the Chart of Accounts?

The chart of accounts is a listing of all accounts used in the general ledger of an organization. The chart is used by the accounting software to aggregate information into an entity's financial statements. The chart is usually sorted in order by account number, to ease the task of locating specific accounts. The accounts are usually numeric, but can also be alphabetic or alphanumeric. 

Accounts are usually listed in order of their appearance in the financial statements, starting with the balance sheet and continuing with the income statement. Thus, the chart of accounts begins with cash, proceeds through liabilities and shareholders' equity, and then continues with accounts for revenues and then expenses. Many organizations structure their chart of accounts so that expense information is separately compiled by department; thus, the sales department, engineering department, and accounting department all have the same set of expense accounts. The exact configuration of the chart of accounts will be based on the needs of the individual business.

Chart of Accounts Best Practices

There are multiple best practices associated with the use of a chart of accounts. Implementing them can greatly improve the efficiency of your accounting operations. Here are some best practices to consider:

  • Lock down the accounts. It is of some importance to initially create a chart of accounts that is unlikely to change for several years, so that you can compare the results in the same account over a multi-year period. If you start with a small number of accounts and then gradually expand the number of accounts over time, it becomes increasingly difficult to obtain comparable financial information for more than the past year.

  • Lock down subsidiary accounts. Do not allow subsidiaries to change the standard chart of accounts without a very good reason, since having many versions in use makes it more difficult to consolidate the results of the business.

  • Shut down accounts with immaterial balances. Periodically review the account list to see if any accounts contain relatively immaterial amounts. If so, and if this information is not needed for special reports, shut down these accounts and roll the stored information into a larger account. Doing this periodically keeps the number of accounts down to a manageable level.

  • Require approvals for changes. Given the need for consistency, changes to the chart of accounts should be quite rare. To ensure that only the most essential alterations are enacted, have the controller approve all proposed changes.

Types of Chart of Accounts Formats

The format of a chart of accounts can vary based on the size, industry, and specific needs of the business. Here are the different types of chart of accounts formats that a business might use:

Standard (Traditional) Format

Organized sequentially by account type: assets, liabilities, equity, revenue, and expenses. This format is suitable for small businesses with straightforward accounting needs. Example numbering is as follows:

  • 1000–1999: Assets

  • 2000–2999: Liabilities

  • 3000–3999: Equity

  • 4000–4999: Revenue

  • 5000–5999: Expenses

Multi-Segment (Segmented) Format

Uses multiple segments or dimensions (like department, location, or project) within account numbers. This format is ideal for medium to large businesses needing detailed financial tracking. Example numbering is as follows:

  • 1000-10-01 (where 1000 = asset account, 10 = department, 01 = location).

Industry-Specific Format

Customized to fit industry requirements, such as manufacturing, retail, construction, or non-profits. For example, a construction company might include accounts for project costs, labor, and materials separately.

Activity-Based Format

Focuses on activities or cost centers, useful for cost accounting. This format helps in tracking expenses per activity, such as production, marketing, or administration.

Hierarchical (Parent-Child) Format

Organized in a tree structure with main (parent) accounts and sub-accounts (children). This format is useful for complex businesses needing detailed breakdowns. Example numbering is as follows:

  • 5000 Expenses

    • 5100 Marketing Expenses

      • 5110 Digital Marketing

      • 5120 Print Advertising

Project-Based Format

Tracks financials by individual projects. This format is common in construction, consulting, and service-based businesses. Example numbering is as follows:

  • Project A: 4000-01, Project B: 4000-02.

By choosing the right chart of accounts format, businesses can ensure that their financial information is organized, accessible, and tailored to their reporting needs.

Chart of Accounts Mapping

If you acquire another company, a key task is shifting the acquiree's chart of accounts into the parent company's chart of accounts, so that you can present consolidated financial results. This process is known as mapping the acquiree's information into the parent's chart of accounts.
