The chart of accounts in Xero is the list of categories used to record every transaction, covering income, expenses, assets, liabilities and equity. A well-structured chart of accounts gives you clear, meaningful reports, while a messy one makes your numbers hard to trust, so set it up thoughtfully from the start.

Your chart of accounts is the backbone of your Xero file. Every transaction you record, every report you generate, and every BAS you lodge flows through it. Yet most small business owners set it up once — or let Xero’s defaults run — without ever thinking about whether it actually reflects how their business operates.

That’s a problem. A poorly structured Xero chart of accounts leads to messy reports, incorrect BAS lodgements, and tax returns that take longer (and cost more) to prepare. This guide explains how the chart of accounts works in Xero, what Xero includes by default, how to customise it, and — critically — when you should bring in a professional to set it up properly.

What Is a Chart of Accounts?

A chart of accounts is a structured list of every financial category your business uses to record transactions. Think of it as the filing system for your entire financial operation. Every dollar that comes in or goes out gets assigned to an account — and those accounts determine what appears on your profit and loss report, your balance sheet, and your tax return.

In Australia, your chart of accounts needs to align with ATO reporting requirements. The ATO requires businesses to keep accurate financial records that explain all transactions — and a well-structured chart of accounts is the foundation of that record-keeping. You can read the ATO’s record-keeping requirements at ato.gov.au.

A chart of accounts isn’t just an administrative formality. It’s a management tool. When structured correctly, it tells you exactly where your money is coming from, where it’s going, and whether your business is actually profitable. When structured poorly, it creates noise — and noise makes it impossible to make good decisions.

How the Chart of Accounts Works in Xero

Xero organises every account into one of five types. Understanding these five types is essential before you start adding, removing, or renaming anything.

Assets

Assets are everything your business owns or is owed. This includes your bank accounts, accounts receivable (money customers owe you), equipment, vehicles, and inventory. In Xero, your bank accounts connect directly to your chart of accounts as asset accounts — which is why setting up your accounts correctly from day one matters so much.

Liabilities

Liabilities are everything your business owes. This includes accounts payable (what you owe suppliers), GST payable, PAYG withholding payable, loan balances, and credit card balances. Your BAS liability sits here, which is why correct GST coding in Xero directly affects what appears in this section.

Equity

Equity represents the owner’s stake in the business — what’s left after you subtract liabilities from assets. For most small businesses, this includes owner’s equity, retained earnings, and drawings. If you’re a company, share capital sits here. If you’re a sole trader or trust, the equity structure looks different and needs to be set up to match your entity type.

Revenue

Revenue accounts capture all the income your business generates. Xero lets you create multiple revenue accounts, which is useful if your business has different income streams you want to track separately — for example, separating product sales from service income, or tracking income from different business divisions.

Expenses

Expenses are where most of the customisation work happens. These accounts capture everything you spend to run your business — rent, wages, marketing, subscriptions, professional fees, vehicle costs, and more. The level of detail you build into your expense accounts determines how useful your reports will be. Too few accounts and you can’t see where your money is going. Too many and your reports become unreadable.

Xero’s Default Chart of Accounts — What’s Included?

When you set up a new Xero file, Xero provides a default chart of accounts based on your selected industry. It’s a reasonable starting point, but it’s generic by design. The default accounts are built to work for a wide range of businesses, not specifically for yours.

Xero’s defaults typically include:

• Standard bank and cash accounts
• Accounts receivable and accounts payable
• GST accounts (already mapped to your BAS)
• Basic revenue accounts (Sales, Other Revenue)
• Common expense accounts (Wages, Rent, Advertising, Interest, Depreciation)
• Standard equity accounts

The defaults are workable — but they’re not tailored. A construction business has very different account needs to a professional services firm or a retail operation. A business with employees needs payroll-related accounts structured differently to a sole trader who pays themselves drawings. And if you’re GST-registered, the tax codes attached to each account need to be correct from the start.

Running on Xero’s defaults without reviewing them is like wearing shoes that are roughly the right size — technically functional, but not a good fit.

How to Customise Your Chart of Accounts in Xero

Xero makes it straightforward to add, edit, and archive accounts. You can access your chart of accounts through the Accounting menu, then Chart of Accounts. From there you can:

• Add new accounts — give each account a code, name, type, and tax code
• Edit existing accounts — rename accounts or change their descriptions
• Archive accounts — remove accounts you don’t need without deleting historical data
• Import accounts — use a CSV import if you’re setting up a new file from scratch

When adding or editing accounts, the most important decision beyond the name is the tax code. Xero’s tax codes determine how transactions flow through to your BAS. Getting the tax code wrong means your BAS figures will be wrong — which can trigger ATO attention and result in penalties or interest charges.

Common customisation decisions for Australian businesses include:

• Creating separate revenue accounts for different income streams (especially useful if you have a mix of GST-taxable and GST-free sales)
• Splitting wages into base salary, superannuation, and payroll tax for cleaner reporting
• Adding specific expense accounts for vehicle costs if you want to separate fuel from registration from insurance
• Setting up a dedicated account for owner drawings or director fees
• Creating fixed asset accounts with matching accumulated depreciation accounts for each asset class

If you’re working with a bookkeeper, they should be involved in any significant chart of accounts changes — because those changes affect how transactions get coded going forward, and inconsistency creates reporting problems.

Common Chart of Accounts Mistakes (and Their Tax Consequences)

These are the mistakes we see most often — and each one has real consequences.

Using the wrong tax codes

Every account in Xero has a default tax code. If that code is wrong, every transaction coded to that account will have the wrong GST treatment. This can mean overclaiming or underclaiming GST on your BAS — both of which create problems with the ATO. Overclaiming GST is the more serious error: it can result in a debt, penalties, and interest.

Lumping everything into one or two accounts

Coding all expenses to “General Expenses” or all income to “Sales” makes your Xero file virtually useless as a management tool. You can’t see what’s driving your costs or where your revenue comes from. And at tax time, your accountant has to untangle everything — which takes time and costs you money.

Mixing personal and business expenses

This is particularly common for sole traders and small business owners who use a single account for personal and business spending. If personal expenses end up in your Xero file under business expense accounts, your profit and loss is wrong, your tax return is wrong, and you’re potentially claiming deductions you’re not entitled to.

Not setting up accounts to match your entity type

A trust has different equity requirements to a company. A sole trader reports income differently to a partnership. If your chart of accounts doesn’t reflect your entity structure, your financial statements won’t be ATO-compliant — and your accountant will need to do additional work at year-end to fix it.

Renaming accounts without understanding the downstream effect

Changing an account name in Xero doesn’t change its type or tax code. But it can create confusion — especially if you rename a liability account to look like an expense, or vice versa. Always understand what an account does before you change it.

How Your Chart of Accounts Affects Your BAS and Tax Returns

Your Xero chart of accounts is directly connected to your BAS. Every account in Xero has a tax code assigned to it — and those codes determine what flows into each label on your BAS (G1, G2, G3, and so on). If your accounts are set up incorrectly, your BAS figures will be wrong from the moment you start coding transactions.

The ATO’s record-keeping requirements are clear: businesses must keep records that explain all transactions and support the amounts reported on their tax returns and activity statements. A correctly structured chart of accounts makes meeting this requirement straightforward. A poorly structured one creates gaps in your records that are difficult to explain under audit.

At tax time, your accountant uses your chart of accounts to prepare your financial statements and tax return. If your accounts are categorised clearly and consistently, this process is efficient. If accounts are muddled, misnamed, or misused, the preparation process takes longer — and the risk of errors in your tax return increases.

This is also relevant for management accounting purposes. If you want to use Xero to track performance against budget, identify cost blowouts, or make decisions about pricing or staffing, your chart of accounts needs to be structured with that purpose in mind.

When to Get Your Accountant to Set Up Your Chart of Accounts

There are situations where it makes sense to set up or review your chart of accounts yourself. If you’re a simple sole trader with straightforward income and expenses, Xero’s defaults may get you most of the way there.

But in most cases, getting a Xero accountant in Melbourne to set up or review your chart of accounts is the better investment. Here’s when it’s particularly important:

• When you’re starting a new business — setting up the chart of accounts correctly from day one prevents years of cleanup work later
• When you’re converting from another system — bringing historical data into Xero requires careful account mapping
• When your business has multiple revenue streams — a professional can structure your accounts to give you meaningful segment-level reporting
• When you have employees — payroll accounts need to be set up correctly to flow through to your STP reporting and year-end obligations
• When you’ve grown quickly — businesses that outgrow their original chart of accounts often need a restructure to get useful reporting again
• When your BAS is consistently wrong — this is often a symptom of incorrect tax codes in your chart of accounts

At Pinnacle Accounting & Advisory, we work with Melbourne business owners to set up and review Xero files that are built for their specific business — not just the Xero default. When your chart of accounts is structured correctly, everything downstream (BAS, tax returns, management reports) becomes more accurate and less time-consuming.

Frequently Asked Questions

Can I change my chart of accounts after I’ve already been using Xero?

Yes, you can add, edit, and archive accounts at any time. However, changes to existing accounts affect how historical transactions are categorised, so you need to be careful. If you’re making significant structural changes, it’s worth having your accountant or bookkeeper involved to ensure the changes are applied consistently and don’t create reporting inconsistencies. Archiving an account (rather than deleting it) preserves the historical transaction data attached to that account.

How many accounts should I have in my chart of accounts?

There’s no universal answer — it depends on the complexity of your business. A simple service business might need 30 to 50 accounts. A business with multiple revenue streams, inventory, employees, and multiple asset classes might need 100 or more. The guiding principle is to have enough accounts to produce meaningful reports without so many that your file becomes unmanageable. If you find yourself creating a new account every time a new type of expense comes up, that’s often a sign your structure needs a rethink.

Does the chart of accounts in Xero affect my BAS?

Yes — directly. The tax codes assigned to each account in your chart of accounts determine what figures flow through to your BAS. If GST is coded incorrectly on an account, every transaction coded to that account will produce incorrect BAS figures. This is one of the most common causes of BAS errors for small businesses using Xero. If your BAS figures don’t look right, the first place to check is the tax codes on your accounts.

Get Your Xero File Set Up to Work for Your Business

Your chart of accounts isn’t a set-and-forget task. As your business grows and changes, your account structure should evolve with it. The businesses we work with at Pinnacle Accounting & Advisory consistently get more value from their Xero file when their chart of accounts is tailored to reflect how their business actually operates — not just the generic default.

If you’re not confident your Xero chart of accounts is set up correctly, or if your reports aren’t giving you the information you need to run your business, let’s look at it together.
