A Directors Penalty Notice is a notice from the Australian Tax Office (ATO) that can make you, as the director of a company, personally liable for the tax debts of that company. A DPN typically gives you 21 days to take action to avoid personal liability. A ‘Lockdown DPN’ means there is no escaping liability once the DPN is served on the director. If you don’t have the correct details recorded with the ASIC, you can’t claim the DPN was sent to the wrong address. Keeping on top of your SGT and PAYG obligations is critical. If however you are having trouble, you need to get good advice quickly.
