In wrapping up knowing all about Notices of Assessments matters quite a bit since it helps keep track of whether what’s reported on our tax returns matches up correctly ensuring we handle our tax duties properly


Every year, lots of Australians go through the process of sending in their tax returns. After that's done, there's usually a bit of waiting and wondering about what happens next with those forms we just sent off. Did everything get filled out right? Will I end up paying more taxes or maybe less than I thought? It might be easy to worry over these questions, but the answers are actually found in something called a Notice of Assessment which you get after your submission. This document really helps by giving details on your tax return.

In this blog post, we're going to take a closer look at the Notice of Assessment so you can feel more comfortable when dealing with it. Knowing what this notice is all about is key for anyone trying to handle their taxes properly and making sure they've filed everything correctly. We'll cover what exactly a Tax Notice of Assessment in Australia means, why it matters so much, its parts, how you receive one, understanding its contents and figuring out what steps to take after getting yours.

Understanding the Basics of a Tax Notice of Assessment

In Australia, when it comes to paying taxes on the money you make, you have to fill out a tax return every year. This form lets you report how much money you've made and what deductions or expenses can lower your taxable income. The Australian Taxation Office (ATO) then looks over your details and figures out how much tax you need to pay based on that information.

After they're done checking everything, the ATO sends out a Notice of Assessment. This important paper tells you all about your taxes for that year - like how much income tax needs to be paid, any deductions or credits applied, and if there are any refunds coming back to you. Getting familiar with this notice is key because it helps understand both what the government says we owe in terms of taxes and gives us insight into our financial health.

Definition and Importance

After you've sent in your tax return for a certain income year, the Australian Taxation Office (ATO) will give you something called a Notice of Assessment. This paper tells you what they found when they looked over your tax stuff. It shows how much tax you need to pay or get back and talks about any deductions or offsets.

The big deal with getting a Notice of Assessment is that it lets taxpayers know exactly where they stand with their taxes and money situation. It's like an official note from the ATO saying what they think about your tax return. By checking out this notice, people can make sure everything was added up right—like how much money they made, what deductions were taken out, and if any offsets were applied correctly—and fix anything that doesn't match up.

Components of a Notice of Assessment

A Notice of Assessment breaks down your tax bill and where you stand financially in a way that's easy to understand. Here are the main parts:

  • Taxable Income: At the start, it tells you about your taxable income. This is basically how much money you made that can be taxed.
  • Franking Credits: For those who have them, franking credits will be shown too. These credits come from taxes already paid by companies on their earnings and can help reduce how much tax you owe.
  • With regards to capital gains during the year, if there were any profits made from selling assets like stocks or property, this notice would include information on the capital gains tax due for these profits.

These details aim to give everyone a clear picture of what they need to pay in taxes and assist with planning finances and handling taxes better throughout the income year.

The Process of Receiving Your Notice of Assessment

After you've sent in your income tax return, how quickly you get your notice of assessment depends on the way you chose to lodge it. Here's what happens with each method:

  • With paper lodgment: Going old school and lodging your tax return by mail takes the longest time. After the ATO gets it, expect to wait up to ten weeks (about 50 business days) for your notice of assessment. Remember, it might take about 7 weeks just for them to log your paperwork into their system.
  • Using myTax online: If you decide to lodge online with myTax, things move much faster. You should see your notice of assessment pop up within two weeks.
  • Through a registered tax agent: Similarly, if a registered tax agent handles filing for you, they can also get that notice of assessment over to you in about two weeks.

It's pretty important not only knowing these processing timeframes but planning around them when waiting on that crucial piece of paper from the ATO.

How to Access Your Notice of Assessment Online

Getting your notice of assessment online is really straightforward and handy. Here's how you can do it:

  • With a myGov account, if it's linked to the ATO, your notice of assessment will pop up in your myGov inbox. Just sign into myGov, head over to the inbox, and there it'll be.
  • Through ATO online services as well. After logging into your account, move to "My Profile," then check out the communication history section where you can see and download your notice of assessment.
  • By using a registered tax agent: If they helped you file your tax return, they'd get the notice of assessment for you. You just need to ask them for a copy.

These methods make sure taxpayers have an easy time getting their hands on their notices of assessments from places like Mygov or through other means like contacting their registered tax agents directly after filing their taxes with help or by themselves via ato online services.

Analysing Your Notice of Assessment

Taking a good look at your Notice of Assessment is key to really getting what you need to do about taxes and where you stand with money. Here's what matters most:

  • With the tax bill, this notice tells you exactly how much tax you have to pay based on the income that can be taxed. It's crucial to check if this number is right.
  • For refunds, if it turns out you've paid more than needed, the Notice of Assessment will let you know how much money should come back to you and how it'll happen.
  • On serious hardship, sometimes paying taxes puts people in a tough spot financially. This document might have some options for those who are finding things especially hard.

By digging into your Notice of Assessment carefully, not only can make sure everything about your taxes adds up but also figure out next steps if something doesn't seem quite right.

Deciphering the Numbers and Sections

Understanding the figures and parts of your Notice of Assessment is key to knowing what you need to do about taxes. Here's what you should look at:

  • Taxable Income: Your taxable income is mentioned in the Notice of Assessment. This number is what your tax payment depends on. It's a good idea to double-check this amount to make sure it's right.
  • Refund: If you're supposed to get money back, the Notice will tell you how much and how to get it. Don't forget to go over this part carefully so you can claim any refund due.
  • Tax Bill: The notice also shows how much tax you owe after considering your taxable income. Make sure this calculation makes sense by reviewing it closely.

By looking into these numbers and sections, understanding your tax duties becomes clearer, allowing for informed decisions regarding your assessment.

What to Do If You Find Discrepancies

If you spot any mistakes or issues in your notice of assessment, it's crucial to act on them. Here’s how:

  • Reach out to a registered tax agent: For worries about your notice of assessment, getting help from a tax agent is wise. They can go over your tax return and advise if anything needs fixing.
  • File an objection: When you don't agree with what the ATO says, you have the option to file an objection. This lets you argue against their decision and bring evidence to back up your point.

By following these steps, you make sure everything in your notice of assessment is correct and that you're meeting all tax requirements properly.

Actions Following the Receipt of a Notice of Assessment

After getting your notice of assessment, there are a few steps you might need to take depending on what it says. Here's what some people commonly do:

  1. Audit: Sometimes, the ATO might decide to check your tax return more closely through an audit. If this happens to you, it's really important to work with them and give them any information or documents they ask for.
  2. Amendment: Noticed a mistake in your tax return after seeing your notice of assessment? You can ask for an amendment. This is how you fix errors so that everything about your taxes is right.
  3. Objection: Don't agree with what the ATO has decided based on your tax return? You're allowed to lodge an objection. This means you tell them why you think their decision is wrong and provide evidence that supports what you're saying.

By doing these things when needed after receiving your notice of assessment, you can sort out any problems or concerns and make sure all the details about your taxes are correct.

How to Lodge an Objection

If you don't agree with what the ATO decided about your taxes, you can challenge it. Here's how to go about it:

  • Start by collecting all the proof that backs up your argument. This could be anything from bills, receipts, or any piece of evidence showing why you believe your tax assessment should be different.
  • Next step is to actually lodge the objection. You have two ways to do this: either use the ATO's online services or send in a written complaint. If there’s a registered tax agent handling your taxes, they can also submit the objection for you.
  • When submitting your objection, make sure to clearly state why you disagree with the notice of assessment and include all supporting documents that strengthen your case.

Remember, timing is crucial here. Usually, there’s a window—either two or four years after receiving your Notice of Assessment—to lodge an objection depending on what situation applies to yours. However if facing serious hardship situations might allow for different timeframes.

Amending a Previous Tax Return

After you get your notice of assessment and spot some mistakes or things you missed in your tax return, here's what to do:

  • Start by going through the notice of assessment. Look for any wrong info about how much money you made, deductions that got skipped over, or other slip-ups.
  • Next up, pull together all the paperwork that backs up why you need to make changes. This might be a copy of your tax return, receipts, or anything else that proves your point.
  • Then it's time to send off those corrections. Hand in a copy of your tax return with all the supporting documents showing why an amendment is needed. If there’s a registered tax agent helping out with taxes they can take care of this step for you.

Fixing errors on past returns helps ensure everything about what taxes are owed is right on target.


Getting to grips with your notice of assessment is key for keeping your finances in good shape. It's important to understand every part and know what steps you need to take. Sometimes, things might not add up right, but it's okay because you can challenge and correct any mistakes. Make sure you're on the ball by checking over your notice carefully for any errors.

Frequently Asked Questions

If you're waiting for your notice of assessment and it's taking longer than expected, don't worry. Here's what you can do. Start by checking if your myGov account is connected to the ATO because if it is, your notice should be in your myGov inbox. On another note, logging into the ATO’s online services and heading over to "My Profile" might help too. Once there, look under communication history; that's where notices are usually found. For those who've gone through a tax agent registered with the authorities to file their tax return, remember that they get your notice first so ask them for a copy.

Are There Penalties for Ignoring a Notice of Assessment?

If you don't pay attention to your Notice of Assessment, you could end up in hot water. When this notice shows you owe a tax bill, make sure to clear it by the due date mentioned on the payment advice. If not, expect penalties and interest charges on what you haven't paid yet. The ATO doesn't take kindly to folks ignoring their rules and can go as far as taking money directly from your wages or grabbing some of your stuff until they get what's owed. On the flip side, if money is really tight and paying by the due date seems impossible, getting in touch with the ATO is key. They're open to talking about ways that might ease your burden or even offer special support for those who are really struggling financially.
