Why TaxDates?
Australian small businesses paid millions in avoidable late fees last year. ASIC alone charges $102 for paying your annual review fee up to one month late, and $428 beyond that. The new Payday Super rules mean super deadlines now land every payday instead of quarterly — and a missed deadline triggers the super guarantee charge, which the ATO now assesses automatically. TaxDates keeps every deadline in one place, checked against primary sources.
