How Many Charts of Accounts Should a Company Have? A Practical Guide for Small Businesses

Your chart of accounts (COA) is the backbone of your company’s financial recordkeeping. It’s the organized list of every account used to classify business transactions – from income and expenses to assets and liabilities. But here’s a common question: how many charts of accounts should a company have?

The Short Answer: One Primary Chart of Accounts

In most cases, a business should maintain one central chart of accounts. This ensures consistency, accuracy, and ease when producing financial statements. Having multiple charts often leads to duplication, confusion, and errors in reporting.

When More Than One May Be Necessary

While a single COA is standard, certain circumstances may require multiple versions or customized sub-ledgers, such as:

• Multi-entity businesses: Separate legal entities (e.g., subsidiaries) may require their own COA for compliance purposes.
• Different accounting frameworks: If your company operates in multiple countries, you may need to align with varying local GAAP or IFRS rules.
• Specialized reporting needs: Certain industries (like nonprofits or government contractors) require additional account structures for regulatory compliance.

Best Practices for Structuring Your COA

1. Keep it logical – Group accounts under clear categories: Assets, Liabilities, Equity, Revenue, and Expenses.
2. Avoid clutter – Too many accounts make reporting harder. Only create new accounts when truly necessary.
3. Use a consistent numbering system – For example:
   • 1000–1999: Assets
   • 2000–2999: Liabilities
   • 3000–3999: Equity
   • 4000–4999: Revenue
   • 5000–5999: Expenses
4. Review regularly – At least once a year, audit your COA to merge duplicate accounts and remove unused ones.

Why It Matters

A well-designed COA makes tax filing smoother, gives you accurate financial insights, and helps your bookkeeper or accountant save time – which means saving money.

Final Thought

For most small to mid-sized companies, one chart of accounts is enough. The key is making it detailed enough for useful reporting, but not so complex that it becomes a burden.
