ATO Objection Form: Grounds and Lodgement

Find the Official ATO Objection Form

Use the maintained ATO form page to obtain the form and choose the lodgement channel. It links to the official PDF, so you avoid relying on an old copy saved in another matter.

The taxpayer form is NAT 13471. Most individuals, including sole traders, can lodge through ATO online services via myGov. Businesses can use Online services for business with myID. The taxpayer page also provides the downloadable PDF and instructions for lodging an objection letter.

Tax professionals use NAT 13044 or the objection service in Online services for agents. Being a forensic accountant or lawyer does not, by itself, establish access to that agent channel. Match the representative’s authority and access to the route used.

An authorised contact who is not the taxpayer’s tax agent cannot lodge the objection online on the taxpayer’s behalf. They can prepare material for the taxpayer to submit online, or lodge the taxpayer PDF or an objection letter through the documented paper route.

The ATO charges no fee to lodge an objection. Keep a completed submission copy and the receipt with the client’s approved grounds and attachment schedule.

Check Whether the Decision Can Be Challenged

An objection challenges an objectionable assessment or decision under the relevant tax law. Read the actual notice before choosing a form. Record the assessed period, assessment reference and disputed component, together with the authority that issued it.

Separate the client’s desired outcomes before preparing the submission.

• A mistake in a lodged return can call for an amendment request. An objection can be appropriate where the client disputes an assessment or the ATO’s application of the law.
• An administrative complaint concerns how the ATO handled a matter. It does not replace an objection against the tax decision.
• A request for remission asks the ATO to reduce a penalty or interest charge. Objection rights against a refusal depend on the particular charge and statutory conditions.
• Difficulty paying calls for a payment or relief process. It does not establish that the assessment is wrong.

For example, a general interest charge and a refusal to remit that charge cannot be challenged through the ordinary objection process. Use the ATO’s relevant remission or review route. An objection against an amended assessment also has a limited scope under section 14ZV: it concerns the alteration or addition and matters relating to it.

This procedure concerns Australian Taxation Office decisions. A state revenue decision or Services Australia decision has its own procedure. An evidentiary objection during a hearing is also a different task.

Confirm Authority and the Applicable Time Limit

Confirm who can instruct you and who will lodge before calculating the objection deadline. Retain the client’s authority, identify the taxpayer entity and record the representative’s capacity. Check the ATO’s authorised-contact requirements where the representative is using that route.

The submission needs the taxpayer’s identifying details, including their tax file number or Australian business number, as appropriate. Include the representative’s contact details and the decision information needed by the chosen channel. Keep sensitive identifiers in the submission file, away from public examples or shared training material.

There is no single ATO objection timeframe. Section 14ZW of the Taxation Administration Act 1953 contains different periods for different decisions. The ATO’s decision and time-limit guidance gives the decision-specific categories.

For an original income tax assessment, the applicable period is generally two or four years after the notice is given. Identify the statutory category for that taxpayer and assessment. For an amended income tax assessment, compare 60 days after the amended notice is given with the applicable original-assessment deadline. Use whichever ends later.

Record both calculations and the evidence of when each notice was given. An issue date alone does not establish every delivery date. Do not carry an income tax deadline into a different tax or decision type.

If the deadline has passed, lodge the objection with a written request for extra time under section 14ZW(2). Explain the delay fully, including its circumstances and reasons. Section 14ZX requires the Commissioner to decide that request. Permission to lodge late is separate from acceptance of the substantive grounds.

Write Grounds That Support the Requested Amendment

State what decision must change and why, with each disputed amount tied to a calculation. Section 14ZU requires the grounds to be stated fully and in detail. “The assessment is unfair” gives the decision-maker little to determine.

Begin with the taxpayer, assessment reference and relevant period. State the outcome sought, then give each ground its own number. Separate the facts from the legal proposition and explain how applying that proposition changes the assessment.

A useful ground identifies the challenged treatment, the supporting facts and the relevant law. Add a reconciliation showing the amount assessed, the disputed adjustment and the proposed result. Keep taxable income, tax payable and penalties in separate calculations.

Fictional Objection-Letter Extract

The following extract is hypothetical. It illustrates the connection between a ground and its records, rather than a complete objection or declaration.

Ground 1 concerns the inclusion of a $30,000 receipt in ordinary business income for the assessed year. The taxpayer seeks removal of that receipt from assessable income. The assessment treats total receipts of $120,000 as income. Reconciliation R1 identifies $90,000 as business receipts and the disputed $30,000 as borrowed principal.

The taxpayer’s case is that the $30,000 was received under an enforceable loan agreement with a repayment obligation. Agreement D1, clause 4, records that obligation. Ledger D2, entry L17, records a loan liability. Statement D3, page 6, transaction T08, records the matching credit. The taxpayer submits that the borrowed principal is not ordinary income. The requested taxable-income adjustment is a reduction of $30,000, with the resulting tax recalculated separately.

The statement proves the credit occurred. The agreement and surrounding facts support the argument about its tax character. Calling a deposit a loan in the ledger does not establish the legal result by itself.

Insufficient ground: “The bank description says loan, so remove the deposit.”

Supported ground: Identify the repayment obligation and explain how the agreement, ledger and statement support the claimed treatment. Address contradictory records instead of omitting them.

Assemble the Financial Evidence Index

Build an attachment schedule that lets the objection officer move from each ground to its supporting record. The ATO’s information requirements call for relevant facts and supporting documents.

Hypothetical Attachment Schedule

Identifier	Source reference	Ground supported	Discrepancy or follow-up
R1	Receipts reconciliation, row 12	Ground 1, $30,000 adjustment	Tax effect calculated separately
D1	Loan agreement, clause 4	Repayment obligation	Explain any variation to written terms
D2	General ledger, entry L17	Recorded loan liability	Reconcile entry to return treatment
D3	Bank statement, page 6, T08	Receipt of $30,000	Identify payer from available records

Reconcile the disputed amount through the bank statements, ledger and lodged return. Add invoices or contracts where they explain the transaction. Account for transfers between the client’s own accounts so the same money does not become two claimed receipts.

Separate a client explanation from a fact established by a document. If an agreement is missing, record that absence and identify the other evidence available. Do not label an unsupported recollection as verified or describe an incomplete statement run as complete.

For a large statement bundle, FinTrace saves forensic accountants and legal teams hours of conversion and transaction review. The service produces a searchable ledger and findings report, with PDF filenames and page references that put the supporting bank evidence at hand. That gives the objection preparer more time for the grounds and disputed calculation.

Preserve original files and keep the submitted versions identifiable. A later reconciliation must show what changed and why, without overwriting the version that supported the lodged objection.

Lodge the Objection and Verify Receipt

Lodge through the channel that matches the taxpayer and authorised representative, then retain evidence of receipt. The following steps use the ATO’s published instructions.

1. Approve the final submission. Match the grounds, disputed figures and attachment schedule to the version the client authorises. Complete any late-lodgement request before submission.
2. Open the relevant official service. For a taxpayer online submission, select Tax, then Lodgments, Reports and forms and Lodge an objection. Prepare everything first: the taxpayer online form must be completed in one session and cannot save progress for later.
3. For Online services for agents, start at the Practice level menu. Select Reports and forms, then Lodge an objection. Enter the required information and supply the supporting material through the available form controls.
4. Complete the applicable declaration. Agents must select the Declaration tick box before Submit, using their approved electronic signature. For the PDF route, follow the ATO’s saving and printing instructions, sign the declaration and send it by the fax or postal details in the form.
5. If using a letter, include the required signed and dated declaration from the taxpayer instructions. A representative also needs the client’s signed declaration confirming the information and authority. Retain that additional declaration for the ATO if requested.
6. Save the submission record. Keep the lodged content, attachment list and online receipt ID, plus the acknowledgement or later ATO reference. For fax or post, retain transmission or delivery evidence alongside the submission copy.

A form left open or a failed upload is not confirmation of receipt. If an attachment fails, correct the file problem and confirm which documents the submission actually contains. If submission status is unclear or no receipt appears, check with the ATO before assuming lodgement succeeded. Give the taxpayer details, attempted channel and transmission evidence so the enquiry can be traced.

For a PDF that does not work in the browser, follow the ATO’s instruction to save it to a desktop computer and open it in the specified PDF application. Use the maintained form page for those technical requirements.

Manage Requests and the Objection Decision

Track each ATO information request against the lodged grounds and evidence schedule. Assign a response owner and record the agreed due date. If a record cannot be provided, contact the objection officer before that deadline to explain the problem.

Tax agents can submit additional material through Reports and forms using Submit further information for lodged private ruling/objection. Identify the existing matter and attach the additional evidence, then complete the declaration. Keep a copy of the response and update the evidence index without silently replacing earlier material.

The ATO’s objection-management guidance explains the outcome documents. These include the reasons for decision and an amended assessment where relevant. Compare the outcome with each ground and reconcile any resulting assessment, refund or outstanding amount.

An objection generally leaves the payment due date in place. Interest can accrue on overdue amounts. Record any separate payment arrangement or recovery deferral explicitly, including its terms. Do not infer a collection suspension from the objection receipt.

If the client disputes the objection decision, read the review rights in the outcome notice promptly. Depending on the decision, the next route can involve the Administrative Review Tribunal or Federal Court. Record that separate deadline and preserve the complete lodged objection and subsequent correspondence for the practitioner handling the review.
