Tax time has a way of arriving while everything else is happening. You’re managing clients, staff, suppliers, cash flow and the day-to-day running of the business, then suddenly your accountant needs records, reports and documents from the past financial year.
The process doesn’t need to be stressful. A clear small business tax return checklist helps you pull together the right information, reduce back-and-forth with your accountant and avoid missing details that may affect your final tax position.
Your accountant will need a full picture of what your business earned during the financial year. This includes sales invoices, cash sales, online payments, bank deposits, government grants, insurance payouts and any other business-related income. If you receive money through different channels, such as EFTPOS, Stripe, PayPal, direct transfer or cash, check that everything lines up with your accounting software and bank statements. Small gaps can create bigger headaches later.
Next, review the costs involved in running your business. This may include rent, utilities, phone, internet, software, marketing, insurance, accounting fees, legal fees, repairs, vehicle costs, contractor payments, wages, superannuation, tools, equipment and stock.
The key question is whether the expense relates to earning business income. If something is partly business and partly private, such as a phone, vehicle or home internet plan, only the business portion should usually be claimed. Good records make this much easier; receipts, tax invoices and clear notes can help your accountant claim what’s appropriate while keeping your return compliant.
Your small business tax return checklist should include statements for all business bank accounts, credit cards, loans and finance facilities. Loan and vehicle finance statements are especially important, as repayments often include both principal and interest (these aren’t treated the same way for tax purposes).
If you’ve paid business expenses from a personal account, flag them clearly and provide the supporting invoices. It’s cleaner to keep business and personal spending separate, but if it’s already happened, your accountant can still review it properly with the right records.
If you use Xero, MYOB, QuickBooks or another accounting platform, make sure your accountant has access before tax time. It’s also worth checking that bank feeds are reconciled, sales invoices are up to date, supplier bills have been entered, payroll has been processed correctly and old unreconciled transactions have been cleared.
Your file doesn’t need to be perfect before you ask for help. Still, the cleaner it is, the smoother and faster the tax return process will usually be.
Amounts owed to you, and amounts you owe others, may affect your tax return depending on how your business reports. Review unpaid customer invoices, supplier bills, customer deposits, bad debts and any work completed but not yet invoiced (this is particularly important for businesses that report on an accrual basis).
For builders, developers, trades and project-based businesses, work in progress can also be a major year-end item. Progress claims, variations, retention amounts and unbilled work should all be reviewed before the return is finalised.
If you employ staff, payroll records are a key part of your business tax return. Your accountant may need wage reports, PAYG withholding records, superannuation details, allowances, bonuses, termination payments, WorkCover information and Single Touch Payroll finalisation records. Super should be checked carefully (late, missed or incorrectly processed payments can create tax and compliance issues).
Contractor arrangements may also need review, especially where labour is involved. In some cases, superannuation obligations can apply to contractors, even when they quote an ABN.
If your business is registered for GST, include BAS records, GST reconciliation reports, PAYG instalment details and any BAS adjustments from the financial year. GST mistakes are common. Insurance, motor vehicle expenses, overseas software subscriptions, bank fees and government charges are often coded incorrectly. A proper review before lodgement can help tidy these up and reduce issues later.
If you bought, sold, financed or scrapped business assets during the year, provide the invoices and finance documents (this might include vehicles, computers, tools, machinery, equipment, office furniture or fit-outs). Vehicle claims also need proper support, especially if there’s private use. Keep records for fuel, servicing, registration, insurance, tolls, parking, finance, logbooks and odometer readings where relevant.
For home office expenses, gather records for internet, phone, electricity, office equipment, furniture, software and stationery. If you run the business from home, rather than just doing some admin there, speak with your accountant before claiming occupancy costs such as rent or mortgage interest, as these can have broader tax consequences.
Any ATO correspondence should be sent to your accountant, especially notices about income tax, BAS, PAYG instalments, superannuation, penalties, interest or payment plans. If you’re working with a new accountant, also provide prior-year tax returns, financial statements, depreciation schedules and ATO account statements. These give important context and help avoid errors with opening balances or carried-forward amounts.
A lot of small business tax issues come from the same few habits: mixing business and personal expenses, leaving bookkeeping too late, missing receipts, forgetting online income, coding GST incorrectly, ignoring superannuation deadlines or treating large asset purchases like ordinary expenses.
A good small business tax checklist helps prevent these issues, but it’s not just about ticking boxes. It’s about giving your accountant enough information to understand what happened in your business across the year.
