What Records Do You Need for a Business Tax Return?

One of the first things you will need is a complete record of the income your business earned during the financial year.

This may include:

• Sales invoices
• Receipts
• Online payment records
• Bank deposits
• Merchant facility statements
• E-commerce platform reports
• Other business income
• Interest or investment income related to the business

If your business receives income through several channels, record each source accurately and reconcile it against your accounting records.

For example, income may arrive through direct bank transfers, card payments, online platforms and cash transactions. These records should align with your accounting system and bank statements.

Business expenses are another major part of the tax return process.

Keep records for expenses that relate to running the business, such as:

• Rent
• Utilities
• Software subscriptions
• Advertising and marketing
• Insurance
• Professional fees
• Office expenses
• Travel
• Motor vehicle costs
• Equipment
• Staff costs
• Contractor payments

Invoices and receipts should clearly show what was purchased, when it was purchased and the amount paid.

Not every expense is automatically deductible, and some expenses may need to be apportioned between business and private use.

Keeping detailed records gives your accountant more information to determine the correct tax treatment.

Bank statements are essential because they provide an independent record of money moving in and out of the business.

You should generally retain statements for:

• Business bank accounts
• Business credit cards
• Loan accounts
• Savings accounts used by the business
• Payment platforms where relevant

These statements are often used to reconcile transactions recorded in accounting software.

If business and personal transactions are mixed together, tax preparation can become much more time-consuming.

Using dedicated business accounts can make record keeping clearer and reduce the amount of manual checking required.

If your business employs staff, payroll records are an important part of your tax and reporting obligations.

Relevant records may include:

• Employee wages
• PAYG withholding information
• Superannuation payments
• Leave records
• Payroll reports
• Bonuses
• Allowances
• Employment-related reimbursements

It is important that payroll records match the amounts actually paid through your bank accounts.

Businesses should also keep appropriate records relating to superannuation obligations and employee entitlements.

Accurate payroll records can help identify discrepancies before the tax return is prepared.

If you use contractors or external suppliers, retain invoices and payment records for those services.

This is especially important when contractors make up a significant part of your operating costs.

You may also need to retain records for contractor reporting obligations, depending on the services provided and your business’s circumstances.

Keeping clear contractor records helps distinguish between employee costs, supplier expenses and outsourced services.

If your business purchased equipment, vehicles, computers, machinery or other assets, keep the original purchase documentation.

Useful records include:

• Supplier invoices
• Purchase contracts
• Finance agreements
• Settlement documents
• Installation costs
• Disposal records for sold assets

The tax treatment of an asset may differ from an ordinary operating expense.

Some assets may be depreciated over time, while others may qualify for different treatment depending on current tax rules and the circumstances of the business.

Accurate purchase records help determine the correct treatment.

Businesses should keep records of loans, finance agreements and other liabilities.

This can include:

• Business loan statements
• Equipment finance agreements
• Hire purchase documents
• Interest statements
• Repayment schedules
• Loan establishment documents

The distinction between principal repayments and interest is important because they are treated differently for accounting and tax purposes.

Keeping these records organised can also help ensure the balance sheet accurately reflects what the business owes.

If your business is registered for GST, keep records that support the figures reported in your Business Activity Statements.

These may include:

• Sales records
• Purchase invoices
• GST reports
• BAS lodgement records
• Adjustments
• Credit notes

Ideally, the figures reported throughout the year should reconcile with the accounting records used to prepare the annual tax return.

Regular reconciliations can make year-end tax preparation much easier.

Businesses that hold trading stock may need accurate inventory records at year end.

These records can include:

• Opening stock
• Purchases
• Sales
• Damaged or obsolete stock
• Stock adjustments
• Closing stock

Inventory values can affect taxable income, so incomplete stock records can create problems when preparing financial statements and tax returns.

A proper stocktake at the end of the financial year may be required depending on the business.

If you claim deductions for business-related vehicle or travel expenses, you may need supporting records such as logbooks, receipts and travel documentation.

Depending on the method used, this could include:

• Logbooks
• Fuel receipts
• Registration
• Insurance
• Servicing costs
• Travel itineraries
• Accommodation invoices
• Parking and toll records

Where expenses have both business and private use, accurate records can help determine the appropriate business portion.

If part of your home is used for business purposes, keep records of relevant expenses.

These may include electricity, internet, phone costs, office equipment and other eligible expenses.

The method used to calculate a deduction can affect what documentation needs to be retained.

Rather than estimating these costs at tax time, keeping records throughout the year usually provides a more reliable result.

Previous tax returns, financial statements and supporting schedules can also be useful.

They provide context for:

• Asset balances
• Depreciation schedules
• Carried-forward losses
• Loan balances
• Previous deductions
• Business structure information

These documents can be particularly important if you change accountants or if the business has grown more complex.

Keeping accurate records is not only about compliance.

Reliable financial data can help business owners understand:

• Profitability
• Cash flow
• Margins
• Cost increases
• Tax obligations
• Debt levels
• Business performance

When records are incomplete, decision-making becomes harder because the numbers may not reflect what is actually happening in the business.

Strong record keeping can also help identify issues earlier, rather than leaving them until the tax return is due.

Preparing a business tax return should not require rebuilding an entire year of financial activity from scratch.

Cloud accounting software, regular bank reconciliations, digital receipt storage and consistent bookkeeping processes can make tax preparation much more efficient.

What records are required for a business tax return?

Most businesses need records of income, expenses, bank transactions, payroll, assets, loans, GST, inventory and other relevant financial activity. The exact requirements depend on the business structure and circumstances.

Do I need to keep every business receipt?

You should retain appropriate evidence for business expenses you intend to claim. This may include receipts, invoices, bank records and other supporting documentation.

Can bank statements be used instead of receipts?

Bank statements can help show that a payment was made, but they may not always provide enough detail to establish what the expense was for. Invoices or receipts are generally more useful supporting records.

How long should business tax records be kept?

Record-retention periods vary depending on the type of record and relevant tax or legal requirements. Businesses should confirm current requirements with their accountant or the appropriate authority.

What happens if my business records are incomplete?

Incomplete records can make tax preparation more difficult and may limit the ability to substantiate certain figures or deductions. It is usually better to address missing information before the return is prepared.
