Frequently asked questions
Got Questions? We've Got Answers
Have a question? We’ve answered some of the most common ones below.
What are the deadlines for lodging my individual tax return?
Individual tax returns must be lodged by 31 October each year for the previous financial year ending 30 June. However, when you engage Keystone as your registered tax agent, you automatically receive an extension to 15 May the following year, providing additional time for thorough preparation and optimisation of your return.
Is it worth using a professional accountant for my tax return?
Professional tax preparation ensures you claim all available deductions whilst maintaining perfect compliance with ATO requirements. Our chartered accountants identify deductions that individuals commonly miss, optimise your tax position, and eliminate the risk of errors that could trigger penalties or audit attention. The tax savings typically exceed our fees whilst removing stress from the process.
What personal expenses can I claim as tax deductions?
You can claim legitimate work-related expenses that directly relate to earning your income, including travel, equipment, professional development, and home office costs. The key is proper documentation and ensuring expenses meet ATO criteria. Our tax specialists conduct comprehensive reviews to identify all eligible deductions based on your specific employment situation and maximise your refund potential.
What should I do if I haven't lodged previous tax returns?
Contact Keystone immediately if you have outstanding tax returns from previous years. We'll assess your situation with the ATO, determine any penalties or interest charges, and develop a strategy to bring your tax affairs up to date whilst minimising additional costs. Early action prevents penalties from accumulating and resolves compliance issues efficiently.
How can you help with securing business financing?
Keystone prepares comprehensive financial documentation that strengthens loan applications and improves approval rates. We develop detailed business plans, cash flow projections, profit forecasts, and financial statements that demonstrate your business viability to lenders. Our presentation highlights strengths whilst addressing potential concerns, positioning you for optimal financing terms.
Do you assist with business acquisitions and purchases?
Our business acquisition specialists conduct thorough due diligence on target businesses, analysing financial records, tax compliance history, and potential liabilities. We structure acquisitions for optimal tax outcomes, negotiate purchase terms, and identify risks that could affect future profitability. This comprehensive approach protects your investment and positions the acquired business for success.
