The Tax Agents Services Act 2009 requires us to advise you of your rights and obligations where we are acting for you on taxation matters. In relation to the taxation services provided:

  1. You are subject to the self-assessment system in relation to any of your income tax returns. The Commissioner is entitled to rely on any statements made in your income tax returns. Where those statements are later found to be incorrect, the Commissioner may amend your income tax assessments and, in addition to any tax assessed, you may also be liable for penalties and interest charges.
  2. You have an obligation to keep proper records that will substantiate the taxation returns prepared and which will satisfy the substantiation requirements of the Income Tax Assessment Act. Failure to keep such records could result in claims being disallowed, additional tax being imposed, and the imposition of penalty or general interest charges.
  3. You are responsible for the accuracy and completeness of the particulars and information required to comply with the various taxation laws. We will use this information supplied in the preparation of your returns.
  4. You have the right, as a taxpayer, to seek a private ruling, object to an assessment by the Commissioner and appeal against an adverse decision by the Commissioner.

Certain time limitations may exist for you to exercise these rights. Should you wish to exercise these rights at any time you should contact us so that we can provide you with the relevant time frames and to discuss any additional requirements which may exist.


While our engagement does not include the audit of your financial statements or income tax returns, we are required by the Tax Agents Services Act 2009 to satisfy ourselves as to the reasonableness of the information and claims being made in the income tax returns. The legislation provides the basis for this and may require us to make further enquiries of you or other nominated representatives from time to time in relation to your taxation returns. Where possible, we will endeavour to identify the information that will be required in advance.

To ensure the efficient completion of your work, it is agreed that all information that is reasonably required will be made available in order for us to complete the various engagements agreed.

Some of the agreed work is subject to specific lodgement dates. Our objective is to ensure that all work is completed in time to meet these lodgement dates. Our capacity to complete the work required is reliant on us receiving the work within a reasonable time period prior to those due dates (our recommendation is not less than 45 days) and receiving timely answers to any queries raised. We will agree a work program with you each year, including the dates for both the receipt of work and our completion date.


We will treat as confidential and maintain the confidentiality of all information and records that you provide to us. This information will only be disclosed to a third party where specific authority has been granted for us to provide this information, or where we are subject to a legal duty to disclose the information.

We may also involve appropriately qualified third party and/or outsourced service providers to undertake some aspects of our professional accounting, taxation and advisory services. These personnel will have access to your accounting and taxation records only for the purpose of completing the accounting and taxation engagements agreed. In all cases these personnel will be subject to our supervision and control.

Please refer to our Privacy Policy on our web site for further details.
