A chart of accounts is organized as a numbered index divided into five categories — assets, liabilities, equity, revenue, and expenses — listed in the same order as the financial statements they feed, with each category assigned its own range of account numbers and each account within a category ordered by liquidity or by when the obligation comes due. That single pattern is what makes the chart of accounts a usable tool rather than a running list.
The Five Categories and Their Number Ranges
Every chart, whether it belongs to a solo consultant or a manufacturer with subsidiaries, starts from the same five groupings. Each one gets a numeric range, and those ranges are so widely used that accounting software defaults to them out of the box.
- 1000–1999: Assets. Everything the business owns that holds value: cash, inventory, equipment, vehicles, receivables. Some of these lose value over time and can be expensed under provisions like Section 179 of the Internal Revenue Code, which allows a business to deduct the cost of qualifying equipment in the year it’s placed in service.1Office of the Law Revision Counsel. 26 USC 179 – Election to Expense Certain Depreciable Business Assets
- 2000–2999: Liabilities. Financial obligations the business owes to others: bank loans, unpaid supplier invoices, credit card balances, and payroll taxes collected but not yet remitted.
- 3000–3999: Equity. What’s left when liabilities are subtracted from assets, including money the owners invested and profits retained rather than distributed.
- 4000–4999: Revenue. Income from selling goods or services, before any costs are subtracted.
- 5000 and above: Expenses. The costs of operating the business, from payroll and rent to office supplies and insurance. Most ordinary and necessary business expenses are deductible on a federal return.2Internal Revenue Service. Small Business Rent Expenses May Be Tax Deductible
These ranges aren’t legally mandated for private companies. They’ve simply become universal. Most small and midsize businesses use four-digit codes; larger companies stretch to five or six digits to allow more granularity or to embed entity or department identifiers.
Why the Order Follows the Financial Statements
The chart isn’t arranged alphabetically or by how often each account is used. It follows the order of the financial statements themselves, starting with the balance sheet (assets, liabilities, equity) and moving to the income statement (revenue, expenses).
There’s a practical reason for that sequence. Balance sheet accounts are permanent. They carry balances from one year to the next, so your cash figure on December 31 becomes your opening cash figure on January 1. Revenue and expense accounts are temporary. They reset to zero at the start of each fiscal year, and their net result rolls into retained earnings on the balance sheet. Listing the permanent accounts first and the temporary accounts second matches how financial data actually moves through the reporting cycle.
The ordering also streamlines reporting. When a lender asks for a balance sheet, the first several hundred accounts in the chart map directly onto that document. The income statement pulls from the accounts that follow. Jumble the categories and every report needs manual sorting.
How Accounts Are Ordered Within Each Category
Inside the asset section, accounts run from most liquid to least liquid. Cash and cash equivalents sit at the top because they’re already spendable. Accounts receivable come next, since they turn into cash relatively quickly. Then inventory, then prepaid expenses, then fixed assets like equipment and buildings that would take the longest to convert.
Liabilities follow a parallel logic based on when they come due. Current liabilities — those payable within a year, such as accounts payable and short-term loans — appear before long-term debt like mortgages or multi-year equipment financing.
This isn’t just aesthetic. It’s the standard presentation under Generally Accepted Accounting Principles for commercial businesses in the United States.3Office of Justice Programs.

Where Cost of Goods Sold Sits
Businesses that sell physical products or manufacture goods need a distinct Cost of Goods Sold section, and it gets its own numbering range because it serves its own purpose: calculating gross profit. Revenue minus COGS is gross profit; gross profit minus operating expenses is net income.
In a chart where revenue occupies the 4000 range and operating expenses start at 6000, COGS typically fills the 5000 range. Within it, individual accounts break out raw materials, direct labor, manufacturing overhead, freight-in, and similar production costs. Service businesses that don’t sell physical products often skip this section entirely and jump straight from revenue to operating expenses.
Contra Accounts and Where They Live
Not every account adds to its category. Contra accounts reduce the balance of the account they’re paired with. The most common example is accumulated depreciation. Equipment might sit in the asset accounts at $100,000, but three years of depreciation totaling $30,000 lives in an accumulated depreciation account with an opposite balance. The net on the balance sheet is $70,000.
Contra accounts are numbered right alongside or just after the accounts they offset. If the equipment account is 1500, accumulated depreciation on equipment might be 1510 or 1501. That keeps related accounts adjacent in the ledger. Other common examples include allowance for doubtful accounts, which offsets accounts receivable to reflect the portion you don’t expect to collect, and sales returns and allowances, which offsets revenue. Each one carries a normal balance opposite its parent category.
Parent Accounts and Sub-Accounts
A flat list of hundreds of accounts becomes unmanageable quickly. The parent-and-child hierarchy solves that. A parent account like “Utilities” acts as a header, and beneath it sit sub-accounts for electricity, water, internet, and gas. The sub-accounts track each cost individually while rolling up into the parent total for high-level reporting.
This layered structure lets an operations manager see a detailed breakdown while external financial statements show a single clean line. Most accounting software handles the nesting natively, indenting sub-accounts under their parents and summing them automatically.
The hierarchy also earns its keep at tax time. A partnership filing Form 1065 may need to report certain expense categories in specific detail.4Internal Revenue Service. About Form 1065 A chart with only a broad “Office Expenses” account forces someone to comb through transactions at year-end to separate supplies from postage from software subscriptions. Sub-accounts do that sorting throughout the year.
One caution: don’t create sub-accounts for every possible expense. If a category runs $40 a year, it doesn’t need its own line. The goal is useful detail, not exhaustive cataloging.
Leaving Gaps in the Numbering
Careful setup leaves gaps between active account numbers. If a checking account is 1010 and a savings account is 1020, a money market account can slot in at 1015 later without renumbering anything. Businesses that pack accounts sequentially at launch often regret it once they’ve grown and the chart has become a mess. Skipping by fives or tens between accounts is standard practice.
For publicly traded companies, organized numbering matters beyond convenience. The Sarbanes-Oxley Act requires management to maintain effective internal controls over financial reporting, with external auditor attestation.5U.S. Securities and Exchange Commission. Sarbanes-Oxley Disclosure Requirements SOX doesn’t prescribe a numbering system, but a disorganized chart makes those controls harder to demonstrate.
How the Structure Shifts for Different Entities
The five-category skeleton is universal, but a few situations reshape what accounts populate it.
Cash Basis vs. Accrual Basis
The accounting method changes which accounts the chart needs. A cash-basis business records income when cash arrives and expenses when cash leaves. An accrual-basis business records income when earned and expenses when incurred, regardless of when money moves. The IRS generally requires accrual accounting for businesses with inventory or those exceeding $30 million in average annual gross receipts.
Accrual charts include accounts that cash-basis charts don’t need at all: accounts receivable for money customers owe but haven’t paid, accounts payable for bills received but unpaid, accrued liabilities for wages earned between the last payday and month-end or interest that’s building on a loan but isn’t yet due, and prepaid expenses for costs paid in advance like six months of insurance. Switching from cash to accrual means adding these accounts and reclassifying existing transactions.
Nonprofits
Nonprofits use the same five categories, with differences in equity and expenses. Instead of owner’s equity or retained earnings, nonprofits track “net assets” in two buckets: net assets with donor restrictions and net assets without donor restrictions. Donations that come with conditions on when or how they can be spent stay in the restricted category until those conditions are met.
On the expense side, IRS Form 990 requires tax-exempt organizations to break spending into three functional categories: program services, management and general, and fundraising.6Internal Revenue Service. Form 990 – Return of Organization Exempt From Income Tax The chart of accounts has to support that breakdown, usually through a separate set of expense accounts for each function or sub-accounts that tag each expense by functional purpose.
Multiple Entities
Companies operating through multiple legal entities or subsidiaries face a structural choice: a single master chart used across all entities, or a separate chart for each entity with a mapping up to the consolidated level. A single master chart guarantees consistency and makes consolidation straightforward, at the cost of individual entities carrying unused accounts. Per-entity charts keep individual books cleaner but require careful mapping to avoid consolidation errors. Either way, the numbering scheme needs room for entity identifiers, often through a prefix or segment code that marks which subsidiary owns each transaction.
