Help Centre
Tax debt is one of the most common pressures on Australian small businesses, and it escalates in predictable stages. Acting early usually keeps more options open and costs less.
The ATO offers payment plans and other help for businesses that engage with it, and it expects lodgements to stay up to date even when you can't pay in full. Left unmanaged, overdue tax can lead to interest charges, Director Penalty Notices that make directors personally liable, credit reporting of the debt and legal action.
These guides explain each step as the ATO describes it, what to do first and when to get help from a registered tax agent or adviser. Where some businesses consider refinancing tax debt, we explain that separately and after the ATO options.
