It can sometimes be awkward to manage your business’s tax responsibilities over the holiday period, not least because the Australian Taxation Office (ATO) and Office of State Revenue (OSR) contact centres and online services have reduced availability or close during the peak Christmas and New Year period.
For 2025, the ATO are scheduled to close from noon AEDT on Wednesday, 24 December 2025, and re-open at 8:30 am AEDT on Friday, 2 January 2026, but there will be reduced ATO staff availability, and professional assistance over a traditionally much longer holiday period, so planning ahead for the dates below always helps.
New Year resolutions are often personal, but what about your business? As you look to the year ahead, consider setting goals for the business to achieve and being mindful of the business’ cashflow along the way. If you require help with your goal setting, or cash flow management, please contact your usual Exant Advisor.
While it’s important for business owners and managers to take a break themselves, they do need to remain focussed on key dates in the new year, which we outline below.
