What Records Do I Need for a Small Business Tax Return?

If you run a small business with an ABN in Australia, you must keep records of all your income and expenses to complete your tax return accurately. This includes invoices, receipts, bank statements, and any documents that support your tax deductions.

If you can’t prove it, you generally can’t claim it. That’s the rule. And most problems don’t come from the tax return itself — they come from poor record keeping during the year.

What Records You Must Keep

This isn’t overkill — it’s the minimum. Without these records, your tax return becomes guesswork. And guesswork either costs you money or creates risk.

GoTax is an online tax return system designed for small business owners, freelancers, and ABN holders who want a fast, simple, and accurate way to complete their tax return.

Income Records

You must keep records of all income earned through your business.

This includes:

• invoices issued
• payments received
• bank deposits

Even small or irregular income needs to be recorded. The ATO often has visibility over income streams, so missing income is one of the fastest ways to create issues.

Expense Receipts

If you want to claim a tax deduction, you need a record of the expense.

Receipts should show:

• supplier name
• amount
• date
• description

No receipt = no deduction.

There are limited exceptions, but relying on those is not a strategy.

Bank Statements

Bank statements act as a backup to your records.

They:

• confirm income received
• support expenses claimed
• provide a full transaction history

If your receipts are incomplete, your bank statements can sometimes help — but they won’t replace proper records.

Vehicle Records

If you’re claiming vehicle expenses, you need to support the business-use percentage.

This usually requires:

• a logbook
• records of kilometres travelled
• details of work-related trips

This is one of the most commonly audited areas — and one of the easiest to get wrong.

Asset Purchase Records

If you buy equipment or assets, you need to keep records of:

• purchase price
• date of purchase
• description of the asset

These are used to determine whether the item is:

• immediately deductible
• or depreciated over time

Without these records, the claim can’t be applied correctly.

GST Records (If Registered)

If you’re registered for GST, your record keeping requirements increase.

You need to track:

• GST collected on sales
• GST paid on expenses
• BAS reporting figures

This is not optional. If your GST records are wrong, your tax position is wrong.

The Biggest Mistake: Trying to Rebuild Records Later

Most small business owners don’t keep records properly during the year.

Instead, they try to reconstruct everything at tax time.

That leads to:

• missed deductions
• incorrect claims
• wasted time

And usually, a worse outcome.

Example: Poor Records = Lost Deductions

A sole trader earning $80,000:

• had partial receipts
• no vehicle logbook
• incomplete expense tracking

Result:

• unable to claim full deductions
• higher taxable income

After improving record keeping the following year:

• more deductions claimed
• lower tax payable

Same business. Different result.

Record Keeping vs Guessing

There’s no advantage in guessing.

Make Record Keeping Easy

If your system is complicated, you won’t use it.
