The average Australian misses $1,000-$3,000 in legitimate tax deductions every year — that's $300-$1,000 left on the table at tax time. Most people know about the basics (work from home, car expenses) but miss the less obvious deductions specific to their occupation and situation. This AI-powered tool analyses your occupation, work arrangement, and investments to generate a personalised checklist of deductions you might be able to claim — complete with ATO-compliant rules and record-keeping requirements.
