Loan Guarantees Gone Wrong: Australia 2025 Guide

A loan guarantee goes wrong when the guarantor becomes legally liable for the borrower’s default and the “rescue payment” triggers unexpected tax outcomes (often a denied deduction, a deemed dividend risk in private groups, or CGT consequences), plus insolvency and asset-protection fallout. In Australian accounting practice, the damage is usually compounded by weak documentation (no enforceable indemnity or subrogation evidence), related-party terms that are not arm’s length, and failure to treat the guarantee as a real credit exposure for solvency and Division 7A purposes.

What does it mean when a loan guarantee goes wrong?

It means the guarantor’s “contingent liability” becomes an actual debt, and the guarantor suffers cash loss, legal action, and frequently adverse tax treatment. Accountants see this most often in SME groups where directors guarantee trading facilities, or where one group entity guarantees another entity’s bank loan without arm’s length pricing or documentation.

Common “failure points” include:

• No written guarantee/indemnity file, or missing executed versions
• No written right of indemnity from the borrower to the guarantor (or no evidence it is enforceable)
• The borrower is already insolvent when the guarantee is given or called
• Related-party benefit issues (shareholder/associate receives the economic benefit)
• The guarantee replaces proper Division 7A loan discipline inside a private group
• The guarantor pays and writes it off without substantiating recovery steps

What are the legal consequences for the guarantor in Australia?

The guarantor becomes liable according to the guarantee’s terms, and lenders typically enforce promptly once a default occurs. The legal outcome is driven by contract law and (where relevant) consumer credit protections and unconscionable conduct regimes, but in accounting practice the key point is simple: a guarantee is not “moral support”; it is enforceable credit support.

Key consequences that should be assumed unless proven otherwise:

• The lender can demand payment from the guarantor after borrower default (often without first exhausting borrower recovery, depending on drafting).
• The guarantor may incur:

From an accounting governance perspective, consideration must also be given to directors’ duties and insolvent trading risk if the guarantee supports continued trading while insolvent (Corporations Act 2001).

What are the tax outcomes when a guarantor pays out a loan guarantee?

The tax outcome is frequently worse than clients expect: many guarantee payouts are not deductible under general deduction rules and are treated as capital or private in nature. The correct analysis depends on why the guarantee was given, who benefited, and what legal rights arise after payment.

Is a guarantee payout tax deductible?

Usually no, unless the guarantee is sufficiently connected to gaining or producing assessable income and is not capital, private or domestic in nature. The ATO’s long-standing view is that many guarantee payments are capital or relate to protecting an investment (for example, protecting shares or a business interest), rather than being a revenue expense.

In practice, outcomes often fall into one of these buckets:

• Investment-protection guarantees (common): Non-deductible; may be capital loss/CGT treatment depending on recovery rights.
• Employee/director guarantees for employer finance (fact-specific): Sometimes argued as income-related, but the capital/private character risk is high.
• Business of giving guarantees (rare in SME): If the guarantor carries on a business of providing guarantees/financial accommodation, revenue treatment may be more supportable.

It should be noted that the High Court authority of Sun Newspapers Ltd v FC of T (1938) remains central in distinguishing capital vs revenue character, and the ATO applies those principles in guidance and rulings when characterising guarantee payments.

Does the guarantor get a capital loss or CGT outcome?

Often yes, because paying under a guarantee commonly gives rise to a right to be indemnified by the borrower (a debt owed to the guarantor). If that debt becomes bad, the loss is typically dealt with under CGT (for example, a CGT event relating to a debt/right), unless a specific revenue provision applies.

Practical accounting reality:

• If the guarantor pays $X to the bank, the guarantor typically acquires:
• If the borrower cannot repay, the guarantor’s loss may crystallise when that right is released, becomes irrecoverable, or is otherwise dealt with under the CGT rules.

Because CGT timing and documentation are critical, working papers should capture:

• The date of guarantee execution
• The date of default and demand
• The date(s) and amount(s) paid
• The legal basis for indemnity/subrogation
• Recovery steps taken and evidence of irrecoverability

When does Division 7A become a problem with guarantees?

Division 7A risk arises where a private company provides financial accommodation or confers a benefit to a shareholder or associate. A guarantee can be part of an arrangement that results in a benefit being provided, particularly if the company’s guarantee is effectively enabling a shareholder (or associate) to obtain finance on better terms, or where group structures use company resources to support private funding.

From an Australian accounting practice perspective, the risk markers include:

• A private company guarantees a director’s personal loan used to buy shares, property, or fund private expenses.
• A private company guarantees an associate’s borrowing and later pays out.
• The guarantee substitutes for what is economically a loan or payment from the company to a shareholder/associate.

The ATO’s Division 7A guidance must be consulted for the specific fact pattern (including the operation of deemed dividend rules and exclusions). Consideration must also be given to whether any subsequent “company-to-shareholder” recourse is a complying Division 7A loan, or whether the arrangement is caught by anti-avoidance concepts in Part IVA depending on intent and structure.

Relevant law and guidance to cite in file notes:

• Income Tax Assessment Act 1936, Division 7A
• ATO Division 7A guidance (including practice guidance and interpretative decisions where relevant)

What about interest, guarantee fees, and related-party pricing?

Guarantee fees can be assessable income to the guarantor and deductible to the borrower if incurred in gaining assessable income, but only if the arrangement is properly documented and commercially justifiable.

Key compliance principles (especially in related-party groups):

• Arm’s length pricing and documentation: If entities are related, fees and terms must reflect commercial reality.
• Thin capitalisation / transfer pricing (larger groups): May be relevant for cross-border arrangements.
• GST: Financial supplies and GST treatment can be complex; specific advice is required.

Disclaimer-grade point: GST and financial supply treatment can be highly fact dependent; ATO GST financial supplies guidance should be consulted.

How do accounting standards treat loan guarantees and when do they “blow up” in the financials?

In financial reporting, the “blow up” occurs when a contingent liability becomes probable and measurable, or when expected credit losses must be recognised for financial guarantees (depending on the reporting framework and entity type).

In practice, issues arise when:

• The guarantee is not disclosed as a contingent liability when required
• The entity ignores impairment/ECL style concepts for financial guarantees where applicable
• The group fails to document related-party exposure and the going concern basis becomes questionable

For Australian SMEs preparing special purpose or simplified disclosures, professional judgement must still be defensible and consistent with the applicable reporting framework and engagement scope. Where assurance is involved, documentation expectations rise substantially.

What real-world scenarios cause the worst outcomes?

The worst outcomes occur when a guarantee is used as “informal funding” in a private group and the borrower fails, leaving the guarantor with a non-deductible loss and a compliance mess.

Scenario 1: Director guarantees company overdraft, company fails

What typically happens:

• Bank calls the guarantee after default.
• Director pays, then tries to claim an immediate deduction.
• The ATO position frequently challenges deductibility; CGT treatment may apply to the director’s right of indemnity debt.
• Bankruptcy risk arises if the director has limited assets outside the guarantee.

Practical control that would have helped:

• Documented indemnity, security, and a realistic recovery pathway (even if ultimately unsuccessful), plus early insolvency triage.

Scenario 2: Family trust guarantees operating company loan

Typical pitfalls:

• The trustee signs without documented trustee powers review or beneficiary approvals where required.
• No commercial fee charged; no evidence of benefit to trust.
• When called, the trust’s payment may be seen as capital/investment protection, and the trust may not have liquidity without selling assets.

Scenario 3: Private company guarantees shareholder’s personal borrowing

Common downstream issues:

• If the company pays under the guarantee, it may be treated similarly to a payment/loan to the shareholder, triggering deemed dividend outcomes unless managed correctly.
• Even before payout, the arrangement can attract ATO scrutiny if it lacks commerciality and documentation.

How should an Australian accounting practice investigate a “failed guarantee” file?

The correct approach is to treat the guarantee as a forensic tax and solvency event: establish legal rights, quantify amounts, map beneficiaries, and then determine the correct tax character and timing.

A practical investigation checklist:

1. Collect primary documents
2. Confirm capacity and authority
3. Determine who benefited
4. Establish post-payment rights
5. Assess recoverability and evidence
6. Tax character and timing analysis
7. Prepare defensible working papers

How can you prevent a loan guarantee from going wrong?

Prevention is primarily documentation, pricing, and governance—done before the guarantee is signed, not after default.

Controls that materially reduce client harm:

• Formal indemnity and security from borrower to guarantor: If the guarantor pays, there must be a real recovery pathway, not a “handshake”.
• Commercial terms and (where appropriate) a guarantee fee: Particularly for related parties.
• Purpose and benefit memo: A short memo recording why the guarantor entered the guarantee and how it connects to income production.
• Solvency and cashflow stress testing: Particularly if the guarantee supports ongoing trading.
• Division 7A review for private groups: Especially where a private company is guarantor and a shareholder/associate is the economic beneficiary.
• Annual review of contingent liabilities: Confirm disclosure and ongoing appropriateness.

How does MyLedger help document and manage guarantee-related risk in practice?

MyLedger is not a “legal guarantee drafting tool”, but it materially improves the accounting controls that stop guarantee events becoming unmanageable—particularly around reconciliation evidence, working papers, and ATO-facing compliance hygiene.

From an Australian practice workflow perspective, MyLedger’s advantage over general-ledger-only tools (including a typical Xero-only workflow) is that it automates the evidence trail and the compliance pack around the event.

Key advantages (practice-focused):

• Automated bank reconciliation (AI accounting software Australia):
• Automated working papers:
• ATO integration accounting software:
• Division 7A automation (within working paper discipline):

What is the best-practice workflow after a guarantee is called (step-by-step)?

The best practice is to run a structured “guarantee incident response” across tax, accounts, and compliance.

1. Freeze the timeline
2. Reconcile the cash movements immediately
3. Create an enforceability pack
4. Recognise the correct accounting entries
5. Assess impairment / irrecoverability
6. Tax analysis and positions
7. ATO-facing compliance check
8. Document and sign off
