The Australian Taxation Office (ATO) resolved 30,429 objections in the 2023-24 financial year, around 30% more than the previous year. An objection is a formal, written challenge to an ATO decision that asks the ATO to review the decision and, where appropriate, change it.
For crypto taxpayers, this process can apply when an individual or business disagrees with an ATO decision affecting their tax position. This guide explains who can object, what to include, how to lodge an objection and what happens afterwards. However, objections to amended assessments are covered separately, so this guide focuses on the mechanics of challenging other ATO decisions.
Key Takeaways
- There is no fee to lodge, and time limits range from 60 days to several years.
- Objecting generally does not stop interest from accruing on a disputed tax debt.
- Strong evidence, such as exchange statements and cost-base workings, decides most crypto objections.
- Individuals, sole traders, businesses and tax agents can all lodge an objection online.
What Is An Objection To An ATO Decision?
An objection is your formal request for the ATO to reconsider a decision about your tax affairs. It differs from simply calling to query a bill. A properly lodged objection creates a legal right to a decision. It also opens the door to external review.
How An Objection Differs From A Review Request?
The ATO also offers an informal review before a formal objection is lodged. The table below sets out the main differences between the two paths.
Feature | Objection | Review Request |
Formality | A formal, written legal process | An informal request, often by phone |
Who Decides? | A different ATO officer to the original decision maker | May be the same area that made the decision |
Time Limit | A strict limit applies, from 60 days to several years | No fixed limit, but delay can affect your options |
Next Step If Refused | External review through a tribunal or court | Lodging a formal objection |
Which ATO’s Crypto Tax Decisions Can You Object To?
Crypto taxpayers most often object to decisions tied to reported gains, income or penalties. The ATO’s guidance lists many objectionable decisions across all tax types. For crypto activity, the most relevant are:
- An income tax assessment that includes disputed crypto gains or income
- An amended assessment issued after a data-matching mismatch
- A penalty for a false or misleading statement
- A decision not to remit shortfall interest charge (SIC), where that interest exceeds 20% of the shortfall
- A decision not to remit an administrative penalty of more than 2 penalty units
- A decision to retain your refund while the ATO verifies your figures
- A goods and service tax (GST) assessment or amended assessment for a crypto business, such as one trading digital currency
- A super guarantee charge assessment, relevant to a crypto business paying staff in crypto
- A notice about an self-managed super fund (SMSF’s) complying fund status, relevant to an SMSF holding crypto
Is Your Situation Eligible For An Objection?
Eligibility depends on the decision type and the time that has passed since it was made. The ATO sets a fixed window for each category. The table below sets out the time limit for each decision type relevant to crypto.
Category | You Can Object To | Time Limit |
Income Tax | An assessment | 2 years from the date received, for most individuals and small to medium businesses |
An amended assessment | The later of 60 days from that notice, or the original limit | |
A decision to retain your refund | Starts 90 days after you lodge | |
Goods and Service Tax (GST) | An assessment | 4 years and one day from the date given |
An amended assessment | The later of 60 days from that notice, or 4 years from the original | |
A decision to retain a refund | Starts 91 days after you lodge your activity statement | |
Superannuation | A super guarantee charge assessment | 60 days (employees generally cannot object to their own) |
A notice about SMSF complying fund status or trustee disqualification | 21 days from the decision | |
Penalty And Interest | A penalty for a false or misleading statement | The later of 60 days from the notice, or the related assessment’s deadline |
A refusal to remit a penalty over 2 penalty units | 60 days | |
A refusal to remit shortfall interest charge | 60 days, only where interest exceeds 20% of the shortfall |
Note: The clock generally starts from when the ATO gives you the notice, ruling or other correspondence. Post is treated as given 7 business days after issue. If you are outside a time limit, you can request an extension in writing with your objection.
What Should Your Objection Include?
A complete objection moves faster than one the ATO must send back for missing detail. The ATO expects specific information regardless of what you are objecting to. Two elements matter most for crypto taxpayers, covered in the two sections below.
Your Contact Details And The Decision You Are Objecting To
Every objection must include your full contact details, such as your name, phone number and email. It must also identify the exact decision, including the relevant tax year.
A business objecting includes its Australian business number (ABN), and an SMSF trustee includes the fund’s details and their own. If someone else lodges for you, include their name, contact details and their tax file number or business number.
Evidence That Supports A Crypto Objection
The ATO has no crypto-specific supporting-information page. This is our own practical guidance, not an ATO statement. Strong crypto evidence usually mirrors what the ATO would expect for any capital gains dispute, though a business or an SMSF needs some additional records. Useful documents include:
- Exchange transaction histories showing every trade, deposit and withdrawal
- Wallet addresses and transfer records between your own accounts
- Cost-base workings showing how each disposal’s gain or loss was calculated
- Records of any lost, stolen or scam tokens affecting your reported figures
- For a business, records of crypto payments made to staff or received from customers
- For an SMSF, the trust deed and investment strategy showing the crypto holding was permitted
Attach these directly to your written objection, alongside a clear explanation of why you disagree. The general capital gains supporting-information guidance covers the same principle for other asset types.
How Do You Lodge An Objection To The ATO?
There is no fee to lodge an objection with the ATO. The lodgment path differs slightly for individuals, businesses and those represented by a tax agent. Each path below is a short, sequential process.
Lodging As An Individual Or Sole Trader
- Log in to ATO online services for individuals and sole traders through myGov
- Locate the objection form within online services, or download the PDF form for taxpayers
- Complete every required field, including your reasons and any supporting documents
- Submit the objection, or post it if you used the paper form
- Note your receipt ID, which confirms the ATO has received it
Lodging As A Business Or Through A Tax Agent
- Log in to Online services for business using myID, or to individual services via myGov
- Complete the same Objection form for taxpayers used by individuals
- Attach the supporting evidence relevant to the business decision
- Submit the objection online, or have your registered tax agent lodge it for you
- Confirm receipt through your online services account or your agent
Authorising Someone Else To Lodge For You
- Nominate your authorised contact, such as a spouse, relative or legal representative
- Update your authorised contact details with the ATO before they act for you
- Have your contact prepare material for you to lodge, since only a tax agent can lodge online for you
- Alternatively, lodge using the paper form or an objection letter
- Include a signed declaration from your authorised contact with that lodgment
What Happens After You Lodge Your Objection?
Once lodged, your objection moves through a set process before a decision is made. The ATO explains its own responsibilities during this period. Understanding each stage helps you know what to expect and when to follow up.
How The ATO Manages Your Objection?
Here is how ATO manages your objection:
- Acknowledgement: Online lodgments receive a receipt ID immediately. Paper lodgments trigger an automated text message once received.
- Contact During Review: The ATO may contact you or your agent to discuss the objection, request information or explain timeframes.
- Your Role: Responding quickly to any request helps avoid delays. Contact your objection officer before a due date if you cannot meet it.
- The Decision: You receive a notice with reasons, any amended assessment, and payment details or a refund, as relevant.
Requesting In-House Facilitation Or Dispute Assist
Two additional supporters sit alongside the standard objection process. Both are free, and each suits a different kind of difficulty. Neither replaces lodging the objection itself.
In-House Facilitation
In-house facilitation is available to individuals, small businesses and not-for-profits with a tax or super dispute. An independent ATO facilitator helps both sides explore options. This can reach a resolution faster than a full formal decision.
Dispute Assist
Dispute Assist suits people who cannot afford paid help, or who face significant personal circumstances affecting the dispute. Request it on the objection form itself, or by emailing the ATO if you have already lodged.
What If You Disagree With The Outcome Of Objection?
An unfavourable objection decision is not the end of the process. You still have a further right to have that decision reconsidered independently. Two paths sit outside the ATO altogether. Each uses a different body, and each carries its own separate time limit.
Applying To The Administrative Review Tribunal
The Administrative Review Tribunal (ART) offers an independent review of the ATO’s objection decision. It is generally faster and less formal than a court. The tribunal can affirm, vary or set aside the ATO’s decision. Its own time limit and process are set out in the ATO’s notice of decision.
Appealing To The Federal Court
You may instead appeal directly to the Federal Court. This path suits disputes turning on a point of law rather than the facts. A Federal Court decision can also be appealed further, unlike a tribunal decision in some circumstances. The ATO’s notice of decision explains this option too.
How Can KoinX Help You Build A Crypto Objection?
An objection succeeds or fails on evidence, not on how strongly you disagree. Scattered exchange and wallet records make that evidence hard to assemble under time pressure. KoinX brings your crypto transaction history together and calculates your gains under Australian Taxation Office rules.
Transaction History Report
The Transaction History Report works as a full ledger of trades, transfers, rewards and fees. It is usually the first document behind a crypto objection. Every disputed transaction can be traced back to its original entry.
ATO Complete Tax Report
The Complete ATO Tax Report applies ATO rules to your crypto data. It covers capital gains tax (CGT) discounts, income and portfolio balances. Compare it directly against the disputed assessment to show exactly where the figures diverge.
Quick Edit
Quick Edit lets you promptly fix flagged transaction errors, or seek help resolving them. Correcting an error before it enters your evidence avoids undermining an otherwise strong objection.
Spam Token Filters
Spam Token Filters remove unsolicited spam and scam tokens from your portfolio in one click. These tokens can wrongly inflate reported income, a genuine and avoidable cause of many disputed crypto assessments.
Building an objection under time pressure rarely produces your strongest evidence. Bring your transaction history into KoinX well before any dispute arises. A clean, checkable record is worth more than a rushed explanation written after the fact.
Most disputed crypto assessments trace back to the same root cause. That is a gap between reported and actual holdings. Closing that gap before it becomes a dispute is far cheaper than resolving one afterwards. Review your own records against the ATO’s data now, not after a notice arrives.
An objection is only as strong as the evidence behind it. KoinX turns scattered exchange and wallet data into one clear, ATO-aligned record. Set it up today. A disputed figure then becomes a quick check, not a stressful reconstruction later.
Frequently Asked Questions
Does Lodging An Objection Stop The ATO From Collecting My Debt?
Not automatically. Objecting generally does not change your payment due date, and interest continues accruing on any unpaid amount. However, the ATO usually pauses active recovery action until the dispute is resolved. Paying the disputed amount, where possible, also avoids interest regardless of the objection’s outcome.
Can I Object To A Decision On Behalf Of Someone Else?
Yes, if you are their nominated authorised contact, such as a spouse, relative or legal representative. A tax agent can lodge online directly. Other authorised contacts prepare material for online lodgment, or use the paper form with a signed declaration.
What Happens If I Miss The Objection Time Limit?
You can request an extension of time by including a written request with your objection. Explain the cause of the delay and when you first learned the decision was incorrect. The ATO will notify you in writing whether it accepts the request before considering the objection itself.
Can I Withdraw An Objection Once I Have Lodged It?
Generally, yes. You can withdraw an objection before the ATO decides, usually by contacting your objection officer. Withdrawing does not extend your original time limit if you later decide to lodge again. Confirm any withdrawal in writing to keep a clear record.
