Tax Operations Procedures Mainfreight 2022



To meet the Board’s expectation in the Tax Policy, this document outlines how Mainfreight Group’s tax obligations are met from a compliance and risk management perspective.


This document forms part of the Tax Governance Framework. The diagram below demonstrates the key components of the Tax Governance Framework:



These procedures govern both payroll and non-payroll taxes.


This document applies to all entities in the Mainfreight Group (refer to Appendix One for structure diagram), including the Board, the Audit Committee and all employees with roles that could have tax consequences.

Routine tax complaince 


The tax compliance roles and responsibilities and signing authority for each of the tax types and Group entities is outlined in Appendix Two.

External advisors

Where required, external advisors should assist in the preparation and lodgement of returns.  

External advisors must be used to: 
  • Review income tax calculations prior to lodgement.
  • Prepare transfer pricing documents and intercompany agreements.
  • Advise on significant transactions eg acquisitions.

Independent Review

A 12-month sample of data should be reviewed using data analytics by an external advisor at least every five years for entities / tax types:
  • GST:  With a turnover exceeding $30 million.
  • Customs: Annual imports or exports at the level of $50 million.
  • Payroll: More than 100 employees. 
A health check should be undertaken by an external advisor at least every five years in relation to:
  • The tax fixed asset register.
  • Any entities / tax types that fall below the thresholds outlined above.
  • Fringe benefit tax and withholding tax every five years.

Tax risk management

Identify tax risk

Risk owners[1] and external advisors should identify events, actions or inactions which may present a tax risk and bring these to the attention of the Chief Financial Officer.

The events, action or inaction that may present a tax risk include:
  • Strategic: Non-compliance with the guiding principles in the Tax Policy. 
  • Operational: Changes to the Finance or Payroll Team or their responsibilities for matters. 
  • Financial: Tax refunds being withheld, reassessments or exposure to use-of-money interest. 
  • Compliance: Late lodgement of returns, change in accounting standards and new tax legislations which impact the business. 
  • Regulatory Changes: changes to legislation

Evaluate tax risk

Once a tax risk has been identified, the Chief Financial Officer should assess the tax risk as either a routine or significant tax risk taking into account the impact that the tax risk could have and the likelihood of that tax risk eventuating.

Routine tax risks are tax risks that arise on a regular basis in the ordinary course of business with no unusual complexity or are consistent with historic tax positions.  

Significant tax risks arise outside of the ordinary course of business or have a higher degree of complexity or uncertainty.  Factors that indicate a significant tax risk include:
  • Public knowledge of the tax position would have a negative reputational impact. 
  • More than 30% of the Finance or Payroll Team’s responsibilities will be impacted.
  • The potential tax consequence is greater than $1,000,000, excluding any penalties or interest.
  • The tax position taken varies from industry patterns or past tax positions.
  • There is variation between the economic and legal outcomes.
  • The tax position is being scrutinised by a Revenue Authority (for example, as part of routine audits of other taxpayers, further to a published statement issued by the Revenue Authority or is the subject of litigation).
  • The tax position taken will be reportable to a Revenue Authority. 
External advisors must be engaged in relation to any significant tax risks.

Determin tax risk treatment

Once a tax risk has been evaluated, the Chief Financial Officer (assisted by external advisors, if required) should assess the options available for the treatment of the tax risk which include: 
  • Use controls to reduce the likelihood of adverse tax consequences occurring: For example, voluntary disclosure, written guidance from a Revenue Authority, maintenance of an evidence file, contract conditions, development of manuals, supervision or training.
  • Use controls to reduce the impact if adverse tax consequences occur: For example, contingency planning, inclusion of contract conditions, business continuity plans, off-site back-up and public relations.
  • If adequate controls cannot be implemented, avoid the tax threat: Do not take a tax position that presents a tax risk.

Determine whether the tax risk should be escalated

If, after controls are implemented:
  • An external advisor cannot provide a more likely than not to be correct2  / should3  opinion (exposing Mainfreight Group to significant shortfall penalties); 
  • The tax position will be reportable to a Revenue Authority; and/or
  • There is a moderate chance of negative reputational damage; 
the tax risk should be escalated to the Audit Committee immediately for consideration

Implement and monitor control

If the tax risk is accepted and controls are implemented, the Chief Financial Officer is responsible for implementing and monitoring the effectiveness of the control.

Reporting to the Audit Committee

At least annually, a Tax Status Report (refer to Appendix Three) should be prepared for each country that Mainfreight Group operates in.
[1] A Risk Owner is the CFO or anyone the CFO has delegated responsibility for the implementation of a control. In practice mainly regional Financial Controllers.
[2]A ‘more likely than not to be correct opinion’ will support the merits of tax treatment of an item if challenged. In numeric terms, a more likely than not to be correct tax position has a 51% (or greater) chance of occurring.
[3]A should opinion supports the merits of tax treatment of an item to the extent that although not entirely free from doubt, the taxpayer's position should prevail. In numeric terms, a Should Opinion can be obtained where there is at least an 80% likelihood that the tax treatment of the item will be upheld if challenged


Tax compliance & tax risk reporting

External Advisors

When to engage

External advisors should be engaged to assist with the management of taxes as required, however, must be engaged to assist with the management of any signficiant tax risks. If matters are particularly complex, sensitive or material, a second opinion from an accounting or legal firm or Counsel’s opinion can be obtained.

Who to engage

Where possible or practical, external advisors from a ‘Big Four’ professional services firm should be engaged at regional level.  When deciding which external advisors to engage, consideration should be given to whether the matter requires an advisor with specialist and/or industry knowledge.

Level of opinion

Where there is a significant tax risk, an opinion should be sought from external advisors.  If a tax position to be taken:
  • Is uncertain, written advice (for example, via a binding ruling or indicative view) should be obtained from a Revenue Authority.
  • Presents a risk of significant shortfall penalties being imposed, the tax position should not be taken. 

Additional Support

In addition to seeking an opinion from external advisors, additional support may need to be maintained in relation to the tax position.  Options available include:
  • Transaction document in support of legal position.
  • Evidence file with contemporaneous document in support of tax position.

Stakeholder relationships

Revenue Authorities

Assisted by external advisors, the Chief Financial Officer should determine how to maintain an open, honest, and co-operative relationship with Revenue Authorities taking into account the size of the business in that jurisdiction.  Options available may include:
  • Regular or pre-lodgement meetings with the Revenue Authority.
  • Responding to information requests (formal or informal) in a timely manner.
  • Making voluntary disclosures where an error is detected.
  • Seeking binding rulings or indicative views from the Revenue Authority where there is uncertainty around a tax position.
  • Submitting on proposed tax policy changes that may impact the business.  

Other stakeholders

The Chief Financial Officer must review the tax disclosures made in the annual report prior to finalisation.

Training and awareness

External Training

To keep up to date on tax matters which could impact Mainfreight Group, the Chief Financial Officer, Finance Team and Payroll Team should regularly attend external tax trainings.

Internal Training

To cascade knowledge across the business and promote ownership of tax governance, the Chief Financial Officer, Finance Team and/or Payroll Team should provide an annual tax update to the business.

Document management

Tax records

Tax records in accordance with statutory obligations in each jurisdiction should be centrally maintained. Where a tax event spans over several years, the tax record should be maintained for at least the minimum statutory period from the end of the tax year affected by the tax event

Drafts / finals

Generally, if the final version of a tax record can be located, draft tax records should not be retained. However, drafts should be retained where it supports a tax position taken or evidence intentions (for example, where a third party has requested the draft tax record be amended).


Documents that are subject to a non-disclosure right or legal professional privilege should be clearly marked as such.

Papers to the Audit Committee should not include summaries of tax advice received.  Rather, the paper should state that tax advice has been received and a copy of that advice should be attached.  If summaries of advice are required, the external advisor should prepare the summary.

Before any tax document that is requested by a Revenue Authority as part of a risk review or audit is made available to a Revenue Authority or a third party, the document should first be reviewed by external advisors.


Prior to destroying any tax record, consideration should be given to:
  • The jurisdiction’s record retention requirements.
  • The significance of the record.
  • Whether the record relates to a tax year that may be subject to an audit or risk review.
  • Whether the record has been provided to a Revenue Authority.
Whether the record relates to a tax position which spans over more than one income year.

Administration of Procedures


These Procedures will be implemented by:
  • Communication with those covered by the scope.
  • Team training, including induction training for members of the Finance and Payroll Team.
  • Being placed on the intranet.


These Procedures should be reviewed annually by the Chief Financial Officer who will propose any changes, if appropriate, to the Audit Committee.


Compliance with these procedures will be assured through:
  • Annual reporting by the Chief Financial Officer to the Audit Committee
  • External advisors testing compliance with the Tax Procedures every three years

Point of contact

The Chief Financial Officer is the point of contact for matters arising in relation to the Procedures.
