Filing a company tax return is an annual obligation for all incorporated businesses. The return reports your company's taxable income, deductions, tax offsets and the resulting tax payable. Accuracy is critical - errors can trigger audits and penalties. Having clean, well-organised books throughout the year is the single most important factor in making your company tax return straightforward and accurate.
Ensure all financial records are up to date and reconciled for the full year
Prepare financial statements - profit and loss statement and balance sheet
Calculate taxable income (accounting profit adjusted for tax differences)
Identify and calculate all available tax deductions and offsets
Complete the company tax return form for your jurisdiction
Lodge the return by the due date (or engage a tax agent for an extended deadline)
Pay any tax owing or note the refund amount
Keep all supporting documentation for the required retention period
Businesses in Australia operating under the GST + BAS system must meet these compliance requirements set by ATO:
Not reconciling all accounts before preparing the tax return
Missing deductions that could reduce taxable income
Confusing accounting profit with taxable income
Not making adequate tax provision payments throughout the year
Filing late and incurring penalties
Not engaging a tax professional for complex situations
