Crest Accountants prepares and lodges company tax returns and business tax returns for sole traders, partnerships, trusts and companies, and has done that from Burleigh Heads since 1973. We act for businesses across Queensland and around Australia, and where you are based makes no difference to how the return is handled.
Very few returns go wrong on the arithmetic. They go wrong on timing: a deadline that moved without anyone noticing, a shareholder loan that could have been fixed in April but not in July, a resolution that needed signing twelve months before lodgement. We lodge the return, and we raise what has to be decided before the year closes rather than after.

When your business tax return is due
Most of the confusion here comes from 31 October being repeated as if it were everyone’s date. It is the date for a self-lodging individual, partnership or trust. It is generally not the date for a company, though there are circumstances, below, where a company does land on 31 October.
If you lodge your own company return and balance on 30 June, the ATO’s income tax due date for self-preparing entities is 28 February, and that is the payment date as well as the lodgement date.
Engage a registered tax agent and it changes. Under the ATO’s lodgment program for companies, most company clients of an agent are due 15 May, with payment the same day. Entities whose prior year total income exceeded $2 million are due 31 March, again with payment the same day.
That concession is conditional, and easily lost. Any entity with one or more prior year returns outstanding at 30 June is due 31 October, with payment on 1 December. One overdue return pulls the next one forward by roughly six and a half months, automatically, and nobody writes to tell you.
That earlier date applies while returns are outstanding, not permanently. Bring the overdue returns in and keep lodging on time, and the extended lodgment program date comes back the following year. Catching up a backlog is work we do regularly, and it is worth finishing before 30 June so the next year is not caught by the same rule.
If you are using a tax agent for the first time, or changing agents, the ATO says you should contact them before 31 October to be in their lodgment program, or the extended date may not be available that year.
The dates are not uniform across a group. On the individual and trust side of the lodgment program, a trust whose latest return produced a liability of $20,000 or more is due 31 March rather than 15 May. Those entities also get staggered payment dates keyed to lodgement, running from 21 March to 5 June, so for them lodgement timing is a cash flow decision as well as a compliance one. Companies and super funds get the 5 June concession only where both the prior and current year are non-taxable or produce a refund. Run a company and a trust, assume the two work the same way, and one will be late.
Being late has its own cost. The failure to lodge penalty runs at one penalty unit for every 28 days or part of 28 days a document is overdue, up to five units, doubled for a medium withholder and multiplied by five for a large one. The ATO generally warns first and can remit the penalty once the documents are in, and safe harbour may apply where a registered agent was given everything in time. The penalty is usually not the expensive part. The interest on an unpaid liability is, and since 1 July 2025 that interest is not deductible.

Lodging early can close a Division 7A window
Where a private company has paid or lent money to a shareholder or an associate during the year, the deadline to repay it or put it under a complying loan agreement is the company’s lodgment day, and the ATO defines that as the earlier of the due date for lodgment or the actual date of lodgment.
The consequence is counter-intuitive, and it is why we ask about drawings before finalising anything. Lodging early closes the window early: lodge in September and you have given away eight months of the time you had to deal with a drawing. Raise the loan account before the return is finalised, not after. Our explainer on how Division 7A treats money taken out of a company covers the mechanics.
What your business lodges depends on its structure
We work with sole traders, partnerships, trusts and companies, whether you are lodging for the first time, have years to catch up on, or run several entities that have to line up. The four structures are not four versions of one form: the ATO sets out different obligations for each, changing who lodges, who pays, when, and what has to be decided in advance. One rule is common to all four. The ATO’s guide to lodging a return for your business is clear that if you carried on a business, something has to be lodged even in a year it earned nothing. Where there was genuinely nothing to report that lodgement is a return not necessary form rather than a tax return, and the two are not interchangeable.
Sole traders
A sole trader has no separate business return at all. Business income and expenses go inside your individual return, in the business and professional items schedule, under your own tax file number, and you lodge it even if your income sits below the tax-free threshold.
What catches sole traders out is the money they take. You cannot employ yourself, so nothing you draw is a wage, and money or assets taken out for personal use are not deductible. Your own super is not a business expense either: it is a personal contribution claimed in your own return after notifying the fund, which is a different thing from the super guarantee you pay for workers.
Partnerships
A partnership has its own tax file number and lodges an annual return showing business income, deductions and how the net income or loss is distributed. It pays no tax itself. Each partner reports their share and is personally liable for the tax on it, whether or not that share was ever drawn out.
The split is where partnership returns go wrong. A written agreement is not required for a partnership to exist, and where there is none the ATO treats income and losses as distributed equally, whatever the partners understood between themselves. Partners are not employees either, so a nominal salary paid to a partner is a distribution of profit rather than a deductible wage. The ATO expects partnership returns to be lodged progressively so each partner can still meet their own date, which means a slow partnership return makes several people late rather than one.
Trusts
A trust has its own tax file number, and the trustee lodges an annual return regardless of the net income involved, unless the ATO advises otherwise. It includes a statement of how income was distributed, and each beneficiary needs their part before finishing their own return.
The decisive act is not done at lodgement. The trustee’s resolution must be made by 30 June of the year being reported for it to determine who is assessed, and where it is not effective the trustee can be assessed instead, potentially at the top rate. By the time the return is prepared that decision is history, which is the argument for an accountant in the room before 30 June.
Companies
A company is a separate legal entity with its own tax file number, return, tax rate and usually its own PAYG instalments. Its money is its money, not yours, which is why taking cash out informally carries consequences the other structures do not have.
A company lodges every year it is registered, and a final return before ASIC deregisters it. After deregistration no company return can be lodged at all, which is a real problem when something is found afterwards. Profit is distributed as a dividend, franking credits may be attached so shareholders get credit for tax already paid, and a distribution statement has to be issued to any shareholder paid one. Directors carry personal exposure too: under the director penalty rules a director can be made personally liable for certain unpaid tax and super debts, which is why the return, the activity statements and the super are looked at together.

From accounting profit to taxable income
Your accounting profit is the starting point, not the answer. The return reconciles it to taxable income, and there are two kinds of adjustment.
The general rule is straightforward: an expense is deductible where you incurred it in earning assessable income, apportioned where it is partly private. That covers most of what a business spends. The return is decided by the exceptions rather than the rule.
Permanent differences never come back. The ATO’s list of what a business cannot claim includes entertainment other than an entertainment-related fringe benefit, traffic fines, private or domestic expenses, expenses relating to non-assessable income, and the GST component of a purchase where you claim a GST credit for it. Payments to workers can also be denied where the PAYG withholding and reporting obligations were not met. One recent change bites: general interest charge and shortfall interest charge incurred on or after 1 July 2025 are no longer deductible, so carrying an ATO debt costs more after tax than it used to.
Timing differences reverse, just not in the year you expect. Tax depreciation replaces book depreciation. Prepayments of $1,000 or more are apportioned rather than claimed up front where you will not receive the goods or services in full within 12 months. Employee super is deductible only where paid on time to a complying fund, so the June contribution still in the bank account at 30 June is usually next year’s deduction. A bad debt has to be genuinely bad rather than doubtful, and written off in writing before year end, so a provision for doubtful debts is not a deduction. Trading stock moves the number too: an increase in stock value is assessable income and a decrease is a deduction, although simplified trading stock rules let an eligible small business skip the stocktake where it estimates the value changed by $5,000 or less.
Then come carried-forward losses, which behave differently in each structure, and credit for the PAYG instalments already paid during the year.
Which company rate applies
Which rate applies is its own test, and it is regularly stated wrongly. The full rate is 30%. The 25% rate applies only to a base rate entity, and the ATO requires two conditions for the income year: aggregated turnover below the threshold, and 80% or less of assessable income being base rate entity passive income. That passive list includes rent, interest, dividends and franking credits, royalties and net capital gains. A trading company that also holds a property or a large term deposit can cross the line without changing what it does for a living, and lose the lower rate on all of its income.

What's included
The annual return is run and priced as its own job. It can stand alone, or sit inside year-round accounting support where you want someone across the numbers through the year as well. The return engagement covers the whole job, from the accounts through to lodgement:
- Financial statements for the year, reconciled to your bank, loan and asset records
- The income tax return for your structure, sole trader, partnership, trust or company
- The reconciliation of accounting profit to taxable income, and the adjustments that make the two differ
- A deduction review across the categories that actually apply: operating costs, wages and super, motor vehicle, interest on business borrowings, depreciation, home office for sole traders, professional development, and accounting and legal fees
- Dividend and franking records where a company has paid a distribution, and credit for PAYG instalments already paid
- Confirmation of the lodgement and payment dates for each entity you run
- Lodgement as a registered tax agent, and dealing with the ATO on your behalf where something is outstanding
Where an active business asset was sold during the year, the small business capital gains tax concessions are their own piece of work rather than part of the standard return, and we quote them separately.
What we need from you
We get to know you and your business, confirm which entities you lodge for, and tell you the dates that actually apply to each.
We review your financials and set up or streamline your accounting software, so the return is built on reconciled numbers rather than reconstructed ones.
We prepare the statements and the return, take you through the position in plain English, and lodge with the ATO.
We manage your BAS, tax returns and ATO reporting through the year, with regular reports and proactive advice.
To start we need the full-year accounts and the bank and loan statements behind them, the activity statements you lodged during the year, your wages and super records, the fixed asset register, any dividend and franking records, and last year’s notice of assessment. If your bookkeeping is current and reconciled, the return is a short job. If it is not, that is the work, and we would rather say so up front than find it in May.
Most of this moves without you posting anything. We work in Xero and MYOB, so we go straight into the file rather than asking you to export it, and our cloud accounting service covers set-up if your records are still on spreadsheets. From first conversation to lodgement, everything can be handled by phone, video and secure file exchange.

What a business tax return costs
We do not publish a price list, because two things drive the fee and neither is visible until we look. The first is the structure and the volume behind it: a sole trader return built on reconciled bookkeeping is a different job from a company and trust group with inter-entity loans and an asset register that needs rebuilding. The second is how much support you want through the year, as against a single annual engagement.
So we look at what is in front of us and quote before we start. Where the records need cleaning up first, we say so and price that separately rather than letting it appear on an invoice afterwards. The same goes for the one-off pieces of work that sit outside a standard return, a business asset sale and the small business CGT concessions being the common one: they carry their own fee, quoted before we start. Book a consultation and you will have a figure before anyone starts on the return.

Frequently Asked Questions
When is my company tax return due?
Self-lodging with a 30 June balance date, 28 February, payment the same day. Through a registered tax agent, most company clients are 15 May, or 31 March where prior year total income exceeded $2 million. Any prior year return outstanding at 30 June drops you back to 31 October, and it stays there while returns remain outstanding. Lodge the backlog and keep lodging on time and your original due date comes back.
Do I need a separate tax return for my business?
It depends on the structure. A sole trader does not: business income and expenses go into your individual return. A partnership, a trust and a company each lodge their own return under their own tax file number, but only the company pays tax on what it reports.
What happens if I lodge my business tax return late?
Two things, and the second lasts longer. The ATO may apply a failure to lodge penalty of one penalty unit per 28 days or part thereof, up to five units. Separately, an outstanding prior year return at 30 June moves your next return to 31 October, so one late year costs you the extended date the following year too.
Does my company still have to lodge if it did not trade this year?
Yes, something is due every year, but it is not always a tax return. Where a company was registered and carried on a business, a return is lodged even if it earned nothing. Where there was genuinely nothing to report, the right lodgement is a return not necessary form rather than a tax return. We review the year, work out which of the two applies, and lodge the appropriate form, so the ATO’s records stay clean and the lodgment program dates are not lost over a quiet year.
Do I have to be on the Gold Coast to use Crest?
No. Our office is at Burleigh Heads and many clients are local, but we act for businesses throughout Queensland and across Australia, with accounts in cloud software and meetings by phone or video.
