What Is a Chart of Accounts?

It helps organize and categorize every transaction flowing in and out of your business. This list connects your daily tasks to your final financial reports and tax filings.

5 Core Account Types Every US Business Needs
To follow the US GAAP Chart of Accounts rules, you must use five main types of accounts. These Chart of Accounts assets liabilities equity, revenue, and expenses categories help you organize your records for the IRS and your lenders.
1. Assets (what you own): These are the things your business owns. Examples include cash in the bank, unpaid invoices from clients, and office equipment.
2. Liabilities (what you owe): These are the debts that your business owes to others. This includes business loans, credit card balances, and tenant security deposits.
3. Equity (owner’s worth): This shows the value left for the business owners. It includes the money you put into the company and your retained earnings.
4. Revenue (what you earn): This is the income you earn from your operations. For a landlord, this is rent. For a shop, this is sales revenue.
5. Expenses (what you spend): These are the costs of running your daily business. Common examples are rent, utilities, payroll, and software costs.
The COA Numbering System Explained
Numbers help you keep your list in a logical and professional order. Most US businesses use a standard four-digit numbering system. This makes it easy to find specific Chart of Accounts categories when you enter transactions.
Account Type | Number Range | Examples |
Assets | 1000–1999 | Cash, bank accounts, accounts receivable, equipment |
Liabilities | 2000–2999 | Accounts payable, credit card debt, business loans |
Equity | 3000–3999 | Owner’s investment, retained earnings, common stock |
Revenue | 4000–4999 | Service income, product sales, rental income |
Cost of Goods Sold | 5000–5999 | Raw materials, direct labor, merchant fees |
Expenses | 6000–7999 | Rent, utilities, marketing, payroll, insurance |
Always leave gaps between your account numbers. Don’t use 1001 right after 1000. Instead, use 1010 then 1020 for your next accounts. This allows you to add new categories later without breaking the numerical order. You can also use sub-accounts to track smaller details under a main category.
Step-by-Step: How to Set Up a Chart of Accounts (COA)
Setting up your system is much easier when you follow a clear path. A professional Chart of Accounts setup for small business ensures your books are ready for tax time and growth. Use these eight steps to build a strong foundation for your business.
Step 1: Identify your business type and tax needs
Every industry has different rules for tracking money. A landlord must track rental income and tenant security deposits. An online seller needs to track inventory and platform fees from Amazon or Shopify. Look at your tax forms before you begin.
For example, you should research a Chart of Accounts for property management if you own rental properties to ensure you use IRS Schedule E categories. This step helps you pick the right categories from the start.
Step 2: Choose and configure your accounting software
Most US business owners use QuickBooks Online, Xero, or Zoho Books. These tools help you build a list quickly. When you start, go to the settings menu to find the Chart of Accounts (COA) section. Don’t just accept every default category the software offers. Many of those categories might not apply to your specific business model.
Step 3: Define your five main account categories
Every GAAP system uses five core buckets to sort money. These are Assets, Liabilities, Equity, Revenue, and Expenses. This structure is the backbone of your balance sheet and profit reports. Group your accounts into these buckets to keep your financial statements clean. This makes it easy for lenders or the IRS to read your reports.
Step 4: Create a logical numbering system with gaps
Use a four-digit system to keep your list in a professional order. Assign 1000 to Assets and 2000 to Liabilities. Use 3000 for Equity, 4000 for Revenue, and 5000 or 6000 for Expenses. Always leave gaps between your numbers, such as 1010, then 1020. This allows you to add new accounts later without breaking the order.
Step 5: Add industry-specific accounts for better detail
Customizing your list is vital for accurate tracking. For the Chart of Accounts real estate, you must include a “Security Deposits Payable” account. This is a liability because you owe that money back to the tenant.
For e-commerce, add accounts for “Shipping Income” and “Merchant Fees.” These specific labels help you see exactly where you make and lose money.
Step 6: Set up sub-accounts for granular tracking
Sub-accounts allow you to see details without a messy main list. You can have a main “Insurance” account with sub-accounts for “Liability” and “Workers Comp.” This keeps your main reports short and easy to read. It also gives you the deep data you need for making smart business decisions.
Step 7: Test the system with your first transactions
Enter a few real bills and invoices to test your new categories. Check your Profit and Loss report to see where the numbers land. If you’re unsure of the results, learning how to read a Profit and Loss statement will help you confirm that your COA is generating useful data.
Make sure your “Security Deposits” don’t show up as income by mistake. This test helps you catch errors before they become a large problem at year-end.
Step 8: Review and clean up your list quarterly
Your business will change, and your Chart of Accounts (COA) should too. Review your list every three months to find accounts you don’t use. Merge any duplicate categories to keep your books simple and clean. A short list of 30 to 50 accounts is best for most businesses focused on setting up Chart of Accounts in accounting.
Sample Chart of Accounts by Business Type
Your list should match the work you do every day. Here’s a Chart of Accounts example of common industries in the US market:
1. For real estate and property management: You need specific categories like Rental Income and Security Deposits Payable. You must track Repairs and Maintenance, Mortgage Interest, and Property Taxes. Don’t forget to include Depreciation for your buildings on your Schedule E.
2. For e-commerce (Amazon or Shopify): Focus on Product Sales and Marketplace Fees from your sales platforms. You must track Shipping Costs, Returns, and Refunds carefully. Your list needs a section for Inventory and Cost of Goods Sold to show actual profit.
3. For service businesses and CPA firms: Use categories for Service Revenue and Professional Fees for your clients. You should track Contractor Payments, Office Expenses, and Software Subscriptions. This helps you monitor your margins as you scale your firm.

Common Chart of Accounts Mistakes to Avoid
A poor Chart of Accounts setup for small business leads to extra work and messy books. Be aware for these mistakes to keep your system clean, or consider a Chart of Accounts cleanup service if your books are already disorganized:
1. Using too many accounts: Using too many categories makes daily data entry hard for you. You only need the main categories required for tax time and growth.
▸ Try to limit your total list to 50 accounts for better clarity.
▸ Combine similar categories to keep your financial reports short and useful.
▸ Avoid making a new account for every small vendor you use.
2. Missing number gaps: Your business will grow over time. You must leave space in your numbering system for new categories as you scale. This is a fundamental part of learning how to create a Chart of Accounts.
▸ Avoid using back-to-back numbers like 1001 and 1002 in your plan.
▸ Use gaps of ten so you can add sub-accounts very easily.
▸ Leave extra space in the expense section for your new costs.
3. Mixing personal and business funds: Mixing money is a major red flag for the IRS. You must keep your business money in its own bank accounts.
▸ Use dedicated bank accounts for every single business transaction you make.
▸ Record your owner draws in the equity section of your list.
▸ Never pay personal bills from your business credit cards or bank accounts.
4. Ignoring tax form alignment: Your list should match the lines on your official tax returns. This simple step makes tax filing much faster for your professional accountant.
▸ Use categories from Schedule E for your rental property business.
▸ Align your account names with the standard US tax forms you use.
▸ Follow US GAAP rules to keep your books clean and professional.

How many accounts does a small business need?
A small business usually needs between 20 and 50 accounts in their Chart of Accounts (COA) to effectively track finances without unnecessary clutter. The goal is to keep the structure lean (30–40 categories are common) to ensure clear financial reporting, rather than having hundreds of unnecessary accounts.
Can I customize QuickBooks' default Chart of Accounts?

Do I need an accountant to set up my Chart of Accounts?

While QuickBooks and other software offer a default Chart of Accounts template that works for simple setups, an accountant ensures tax compliance, optimal organization, and prevents long-term financial reporting mistakes.
How often should I update my Chart of Accounts?
Review and update your Chart of Accounts (COA) at least annually, ideally before the start of a new fiscal year, to ensure it aligns with tax laws and business structure.
