It is important to understand the notice of assessment, what it is and what it contains for everyone who files tax returns. The notice of assessment is a crucial document you receive after lodging your tax return, let’s explore what it is and what it contains.

What is a Notice of Assessment?

A notice of assessment is an official document issued by the tax office that outlines the results of your tax return assessment. The notice of assessment contains important information, and the notice of assessment is significant because it officially concludes your tax return process. It determines the amount you owe or the refund you’ll receive.

It’s important to review the assessment properly and check that the income deductions and offsets are accurate and show your financial situation. If you identify any discrepancies or errors in the assessment, you can request verification and correction from the tax office. Don’t forget to keep your notice of assessment in a safe place. It serves as an official record of your tax affairs and may be required for future reference or when applying for certain benefits or loans. Understanding the notice of assessment is crucial for managing your tax obligations. Therefore, take the time to review its contents and ensure the accuracy of the information provided. You can also ask small business accountants to understand notice of assessment (NOA).

What Does Notice of Assessment (NOA) Contain?

Your notice of assessment is the statement ATO issues that explain tax assessment calculations. Your NOA will show:

  • the amount of tax you owe based on your taxable income
  • any credit you may have for tax payments made during the income year
  • the total amount you need to pay or the refund you will receive, and
  • any excess reduction or refund for private health (if applicable).

Once you receive your notice of assessment, it is important to review it thoroughly for accuracy. If you have a myGov account connected to the ATO, your NOA and tax receipt will be sent directly to your myGov Inbox. Your tax receipt will provide insight into how your taxes were distributed among various categories of government spending.

If you have a tax debt, then you can check advice from the ATO on why you may get a tax bill. Your notice of assessment will include your payment due date and payment advice. In some cases, the ATO also issues a statement of account with your notice of assessment. In this case, your payment advice and due date are added to the statement of account. According to the law, the ATO has time to review your tax return. During this time, the ATO may increase or decrease the taxable or refundable amount on your initial NOA. This review time is normally 2 years, but in some cases, it can be 4 years.

How Long After Notice of Assessment Do You Get Your Refund?

Usually, you can expect to receive your refund within 2-3 weeks if everything goes smoothly with the return. However, it may take up to 30 days if the ATO is experiencing delays. The refund you are entitled to will be promptly deposited into your account without any further delay.

What If You Think Your Notice of Assessment is Not Correct?

Please review the information on your Notice of Assessment (NOA) and compare it to the details you provided in your tax return. If you made an error while completing your tax return, you can make corrections by amending it. In case you owe a tax debt, the ATO advises you to refer to their guidance on the possible reasons for receiving a tax bill. If you still believe there is an issue, please do not hesitate to contact the ATO for assistance. When you call, please have your notice of assessment and a copy of your tax return (if available) ready.
