What is a Business Tax Return?

A business tax return is the annual income tax return your entity lodges with the ATO to report its taxable income, claim deductions, and calculate tax payable or refundable. The form you lodge depends on your structure: a company lodges a company tax return, a trust lodges a trust tax return with a distribution statement, a partnership lodges a partnership return, and a sole trader reports business income on their individual tax return. Getting the right return, lodged on time, with every deduction claimed — that's the difference between a good accountant and a great one.

Maximise legitimate deductions

We review every expense category — depreciation, motor vehicles, home office, instant asset write-off, super — to claim everything you're entitled to, nothing you're not.

Reduce audit risk

A CPA-prepared return with clean workpapers, correct GST reconciliation and justified deductions is the single best defence against ATO review or audit.

Stay fully compliant

On-time lodgement through a registered tax agent gets you automatic ATO extensions and keeps you clear of Failure-to-Lodge penalties and interest.

Business Tax Returns by Entity Type

Your business structure dictates which return you lodge and how your profit is taxed. Here's how each of the four main structures we work with is treated — if you're still deciding, see our business registration guide.

Company tax return

Companies lodge their own return separate from shareholders. Base rate entities (turnover under $50M) pay a flat 25% company tax rate (2025–26). We handle Div 7A loans, franking accounts, R&D claims and loss carry-back where applicable. See our company registration page for structure advice.

Trust tax return

Discretionary and family trusts lodge a trust return and distribute income to beneficiaries, who pay tax at their marginal rates. We prepare the distribution resolution before 30 June, lodge the return, and coordinate beneficiary individual returns. See our trust setup page.

Partnership tax return

Partnerships don't pay tax themselves — they lodge a partnership return showing how profit and losses are split between partners, who then report their share on their individual returns. See our partnership registration page.

Sole trader return

Sole traders report business income and expenses on a Business & Professional Items schedule within their individual tax return. Profit is taxed at marginal rates (up to 45% + Medicare). See our sole trader page.

Business Tax Return Due Dates (2025–26)

The ATO sets different lodgement deadlines depending on your entity type, prior-year lodgement history and whether you lodge through a registered tax agent. Engaging Y&S Accounting gives you the extended tax-agent dates below instead of the standard self-lodger deadline of 31 October.

1
Self-lodgers

If you don't use a registered tax agent, your business return is due by 31 October following the end of the financial year. No extensions, no exceptions — late lodgement triggers Failure-to-Lodge penalties.

31 October
2
Tax agent clients — small business

Companies, trusts and partnerships with turnover under $2M typically have a 15 May concession, giving you an extra 6.5 months compared to self-lodgers. The exact date depends on your lodgement program category.

Up to 15 May
3
Tax agent clients — individuals & sole traders

Individual tax returns (including sole traders reporting business income) lodged through a tax agent are typically due by 15 May the following year, provided you were up to date at the start of the lodgement program.

Up to 15 May
4
Late lodgement penalties

Failure-to-Lodge penalties apply at $330 per 28-day period overdue (2025–26), capped at 5 units. Interest accrues on unpaid tax. A registered tax agent can also negotiate penalty remission if you have a clean compliance history.

Business Tax Return FAQs

What's the company tax rate for 2025–26?

Base rate entities — companies with aggregated turnover under $50 million and no more than 80% of income from passive sources — pay a flat 25% company tax rate. Larger companies pay 30%. Franking credits are issued at the rate at which tax was paid, which affects dividends to shareholders.

How much does a business tax return cost?

Our fees depend on the entity type and complexity of your books. Sole trader returns with clean Xero files start lower than complex company or trust returns with Div 7A loans, multiple entities, or year-end adjustments. We'll quote a fixed fee in your formal written proposal after the consultation — no surprise bills.

Do I still need to lodge if my business made a loss?

Yes. A business loss return is just as important as a profit return — in many cases more so, because lodging captures the loss and carries it forward to offset future profits. Failing to lodge means you may lose the ability to claim the loss, and you still face Failure-to-Lodge penalties.

What's the difference between tax planning and tax compliance?

Tax compliance (this service) is about accurately preparing and lodging last year's return. Tax planning is about legally reducing next year's tax before 30 June, using strategies like prepayments, super contributions, asset purchases and trust distributions. See our tax planning page — the two services work best as a pair.

Can you catch up multiple years of overdue returns?

Yes. We regularly help clients lodge 2–5 years of overdue returns and negotiate penalty remission with the ATO. The first step is a consultation to scope the work, confirm what the ATO has on file, and build a catch-up plan that protects you from further enforcement action.

What records do I need to give you?

Ideally a complete Xero or MYOB file for the financial year. Failing that: bank statements, sales invoices, supplier bills, loan statements, asset purchases, payroll reports and prior-year returns. If your records are messy, we can clean them up through our bookkeeping service before preparing the return.

How does my BAS affect my business tax return?

Your BAS figures (GST, PAYG withholding, PAYG instalments) flow directly into your annual return. If your BAS has errors, your tax return will inherit them. We reconcile every quarterly BAS against your income tax return to catch discrepancies before the ATO does.
