What is a Notice of Assessment?
A Notice of Assessment (NOA) is a formal document issued by the Australian Taxation Office (ATO) after you have filed your tax return. It outlines the ATO's assessment of your tax liability or refund for the relevant financial year. This assessment is based on the information you provided in your tax return, as well as any additional data the ATO has gathered from other sources.
The Anatomy of a Notice of Assessment
The Notice of Assessment typically includes the following key information:
Taxpayer Details
- Your name, address, and tax file number (TFN)
- The financial year the assessment is for
Tax Return Details
- The date your tax return was lodged
- The type of tax return you filed (e.g., individual, business, or trust)
- Your taxable income for the year
- The tax offsets and deductions you claimed
Tax Calculation
- The total amount of tax you are required to pay or the refund you are entitled to receive
- Any adjustments made by the ATO to your reported income or deductions
- The amount of tax already paid through pay-as-you-go (PAYG) withholding
Payment Information
- The due date for any outstanding tax payments
- Instructions on how to make the payment, including bank account details and payment reference numbers
Additional Information
- Notices or messages from the ATO regarding your tax affairs
- Information about your right to object or appeal the assessment
Understanding Your Tax Liability or Refund
The key information on your Notice of Assessment is the calculation of your tax liability or refund. This section will break down the various components that contribute to this figure:
Taxable Income
Your taxable income is earned minus any eligible deductions and offsets during the financial year. This figure determines the amount of tax you are required to pay.
Tax Rates and Thresholds
Australia's tax system uses a progressive tax rate structure, meaning that different tax rates apply to varying taxable income ranges. The NOA will show the tax rates and thresholds applied to your taxable income.
Tax Offsets and Deductions
Tax offsets and deductions can reduce the amount of tax you owe. Common examples include the Low and Middle Income Tax Offset, the Pensioners Tax Offset, and deductions for work-related expenses, charitable donations, and other eligible items.
PAYG Withholding
If employed during the financial year, your employer would have withheld a portion of your income as pay-as-you-go (PAYG) tax. The NOA will show the total amount of PAYG tax that has been paid, which is then credited against your overall tax liability.
Tax Refund or Balance Due
Based on the calculations above, the NOA will indicate whether you are entitled to a tax refund or if you have an outstanding tax balance to pay. If you are refunded, the ATO will issue a direct deposit to your nominated bank account or send you a cheque. If you have a balance due, the NOA will provide the due date and instructions for payment.
Reviewing Your Notice of Assessment
It's important to carefully review your Notice of Assessment to ensure that all the information is accurate and that you have claimed all eligible deductions and offsets. Here are some key things to look for:
Taxable Income
Verify that your reported income matches the information the ATO has on file. This includes wages, interest, dividends, and other income sources.
Deductions and Offsets
Ensure that all the deductions and offsets you claimed have been correctly applied. Double-check that you haven't missed any eligible claims.
Tax Calculations
Review the tax calculations to confirm that the correct tax rates and thresholds have been applied to your taxable income.
PAYG Withholding
Confirm that the PAYG tax withheld by your employer(s) during the year has been accurately reflected in the assessment.
Payment or Refund
If you have a balance due, ensure the payment due date and instructions are precise. If you are entitled to a refund, verify that the correct amount has been calculated.
What to Do If You Disagree with Your Notice of Assessment
If you believe there are errors or discrepancies in your Notice of Assessment, you have the right to object to the ATO's decision. Here are the steps to follow:
- Review the assessment carefully: Thoroughly examine the NOA and identify the specific areas you believe are incorrect.
- Gather supporting documentation: Collect any relevant evidence, such as receipts, invoices, or correspondence, that can support your position.
- Lodge an objection: You can lodge an objection with the ATO within a specific timeframe (usually 2 years from the assessment date). The objection must be in writing and include a clear explanation of the reasons for your disagreement.
- Await the ATO's response: The ATO will review your objection and provide a decision. If the ATO upholds its original assessment, you can appeal the decision to the Administrative Appeals Tribunal or the Federal Court.
It's important to note that the objection process has specific deadlines and requirements, so seeking professional tax advice is advisable if you plan to dispute your Notice of Assessment.
Keeping Track of Your Tax Records
To ensure a smooth tax filing process and facilitate the review of your Notice of Assessment, it's essential to maintain accurate and organized tax records throughout the year. This includes:
- Keeping copies of your tax returns and Notice of Assessments NOAs for at least 5 years
- Retaining receipts, invoices, and other documentation related to your income and deductions
- Tracking any changes to your personal or financial circumstances that may impact your tax obligations
By keeping track of your tax records, you'll be better equipped to understand your NOA, identify any issues, and ensure you're paying the correct amount of tax.
Conclusion
Your Notice of Assessment is a critical document that provides a comprehensive overview of your tax affairs for the financial year. By understanding the key components of the NOA and how to review it thoroughly, you can ensure that your tax obligations are accurately reflected and take appropriate action if discrepancies arise.

How do I get help with this from the ATO?
The ATO provides guidance through ato.gov.au, the Small Business Support Line (13 28 66), and Online Services for individuals and businesses. For complex situations, a registered tax agent provides advice tailored to your specific circumstances and professional indemnity protection. You can verify agent registration at the TPB register at tpb.gov.au.
What records do I need to keep for tax purposes in Australia?
Most tax records must be kept for five years from the date of lodgement or the date the transaction occurred, whichever is later. Records must be in English or convertible to English and must be sufficient to explain the income and deductions in your return. The ATO can request records at any time during the retention period.
When do I need a registered tax agent in Australia?
Consider a registered tax agent when your affairs involve multiple income sources, business activity, investment properties, capital gains, or overseas income. Agents extend your lodgement deadline, provide safe harbour protection, and take professional responsibility for the advice given. Verify registration at tpb.gov.au.
How does the ATO calculate penalties for compliance failures?
The failure to lodge penalty is based on penalty units ($313 per unit from 1 July 2023), accruing per 28-day period for late returns and BAS lodgements. Incorrect information penalties range from 25% to 75% of the tax shortfall depending on whether the behaviour was careless, reckless, or intentional. Proactive disclosure before an audit begins typically results in significantly reduced penalties.
What is the difference between tax avoidance and tax minimisation?
Tax minimisation is the legal arrangement of your affairs to reduce tax — claiming all eligible deductions, using appropriate structures, and timing income and expenses. Tax avoidance involves arrangements that technically comply with the law but achieve outcomes parliament did not intend. The ATO can apply Part IVA anti-avoidance rules to cancel benefits from avoidance arrangements.
