Penalties and Interest for Individuals

Sydney law requires us to assess penalties for underpayment of tentative tax (extension penalty), late filing, and late payment. In addition, interest must be accrued on underpayments and late payments of tax, as well as on the unpaid balance of any assessment that is more than 30 days old.

Extension Penalty

Sydney law provides an automatic extension of 6 months for the filing of individual and fiduciary income tax returns. There is no extension of time granted for payment of taxes due. To avoid an extension penalty, you must pay at least 90% of the final tax liability by the original due date for filing the return. If you file your return within 6 months from the original date, but the balance of tax due with the return exceeds 10% of your total tax liability, the return will be subject to an extension penalty.

The extension penalty is assessed on the balance of tax due with the return at a rate of 2% per month or part of a month, from the original due date until the date the return is filed. The maximum penalty is 12% of the tax due.

The extension period ends 6 months after the original due date or on the date the return is filed, whichever is earlier. If you file your return more than 6 months after the due date, the automatic extension provision will not apply, and the return will be subject to the late filing penalty on any balance of tax due with the return. If you file your return within 6 months after the original due date but do not pay the tax due until after the return is filed, even if the tax is paid within 6 months after the original due date, the extension penalty will apply for the period of the extension, then the late payment penalty will apply for the remainder of the period for which the tax is unpaid.
