Personal guarantees and director personal liability: where the corporate veil does not protect you

What limited liability actually limits

Limited liability limits a shareholder's exposure to the amount unpaid on their shares. It says almost nothing about a director's exposure — and in most Australian small and mid-sized companies the same person holds both roles, which is why the protection is misunderstood.

Personal exposure arrives through three doors, and closing one does nothing to the others:

• Contractual — a guarantee or indemnity the director signed, triggered by default on a lease, loan or supply account.
• Tax statute — Schedule 1 to the Taxation Administration Act 1953, triggered by unpaid PAYG withholding, GST or superannuation guarantee charge.
• Corporations Act — insolvent trading, breach of duty, creditor-defeating dispositions and employee entitlement avoidance, triggered by failure or a regulator investigation.

Only the first is voluntary; the others attach by operation of law to the office. The general duties behind the third are examined in directors' duties under section 180 and the business judgment rule and indexed at comply with directors' duties.

Personal guarantees: contract, not statute

A personal guarantee is a contract in which a director promises to pay the company's debt if it does not, and its scope is whatever the document says — not what the director assumed.

Guarantees typically attach to bank facilities, usually supported by a mortgage over the director's home; commercial leases, often for the full term plus options; supplier trade credit accounts, where the guarantee sits in the credit application; equipment finance; and franchise agreements.

Four features of the standard document cause most of the damage:

• All-monies rather than capped, so it extends to facilities increased or added later.
• Joint and several where more than one director signs, so a creditor can recover the whole from whichever guarantor has assets.
• Survives resignation, unless the creditor expressly releases it.
• Includes an indemnity, keeping the guarantor liable even where the debt is unenforceable against the company.

Where the guarantor is dealing with a subscribing bank, the Banking Code of Practice provides protections beyond the general law for individuals, small business customers and guarantors. The Australian Banking Association states that the 2025 Code was approved by ASIC on 27 June 2024, that its provisions are legally enforceable, and that it obliges banks to meet intending guarantors before accepting a guarantee. Those protections do not reach a supplier's credit form.

Guarantees in standard form small business contracts may also engage the unfair contract terms regime — see the ACCC's contracts guidance and unfair contract terms and the penalty regime. ASIC regulates unfair terms in financial products including loans.

Statutory liability under the tax law

The director penalty regime makes a director personally liable for the company's unpaid pay as you go withholding, GST and superannuation guarantee charge, without any guarantee having been signed. It is the most common route to personal liability in Australian company failures.

The Australian Taxation Office describes the penalty as a parallel liability: it mirrors the company's, so a payment against either reduces both, and with several directors each is likely to owe the same amount. The ATO can recover 21 days after issuing a director penalty notice, and those days run from when the notice is posted or left at the director's ASIC-registered address — not when it is read.

Four features make the regime unusually sharp:

• New directors inherit exposure. A new director escapes a penalty due before appointment only if, within 30 days, they ensure the company pays the debt or enters a prescribed process. Resigning inside that window does not help.
• Resignation does not clear the past. A former director stays liable for PAYG withholding where the first withholding event in the period preceded resignation, and for GST and SGC where the period ended before it.
• Reporting on time preserves the options. Where the liability was reported within three months of the due date, the penalty can be remitted by paying, appointing a restructuring practitioner or administrator, or beginning to wind up within the 21 days. Reported late or never, the only route is paying in full. Estimates count as never reported.
• Deregistration does not end it. The ATO states that a director liable for a penalty remains liable after the company is deregistered.

The full mechanics, including the statutory defences, are in Director Penalty Notices: the 21-day rule explained, the ATO's director penalties guidance, and the obligation at pay company PAYG, GST or SG or face a DPN. Because the notice goes to the ASIC-registered address, the address obligations in company registers and registered office obligations are load-bearing here.

Statutory liability under the Corporations Act

The Corporations Act creates personal liability in several places, none of which requires a signature.

• Insolvent trading. Civil penalties, uncapped compensation orders payable to creditors, criminal charges where dishonesty is a factor, and disqualification. The maximum civil penalty for an individual is the greater of 5,000 penalty units or three times the benefit obtained and detriment avoided; ASIC states that maximum as $1.82 million at the current unit value of $364 for conduct on or after 1 July 2026 (checked August 2026 on ASIC's fines and penalties page). See insolvent trading under section 588G.
• Breach of the general duties — care and diligence, good faith and proper purpose, improper use of position or information. ASIC notes these can be criminal where dishonesty or recklessness is found, with maximum prison terms for the most serious offences at 15 years.
• Creditor-defeating dispositions — disposing of company property below market value to defeat creditors, with compensation orders available and liability extending to advisers who assist.
• Employee entitlement avoidance. ASIC states it is an offence for anyone, including a director, to enter an agreement or transaction to avoid paying employee entitlements: up to 1,000 penalty units or 10 years' imprisonment or both, plus liability to compensate for loss even without a conviction.
• Disqualification. ASIC may disqualify a person for up to five years where they were involved with two or more companies that went into liquidation within seven years paying creditors less than 50 cents in the dollar, or were an officer of two or more companies in that period that relied on the Fair Entitlements Guarantee.

Ranges can be modelled with the penalty estimator, and the board-level control set with the director duties tool.

Liability that survives resignation, insolvency and deregistration

The most common planning error is treating resignation or closure as an exit.

A person who resigns from a failing company and lets it be deregistered has changed nothing except their access to the records they will need to defend themselves. Confirm too that the cessation was recorded on the ASIC register — an unrecorded resignation leaves the person being pursued as a current director. Check with the director ID check.

What an insolvency process does to a guarantee

An insolvency process suspends enforcement of a personal guarantee in some circumstances and not others, and the difference decides whether a director has breathing room.

• Voluntary administration. ASIC states that a creditor holding a personal guarantee from the company's director or another person cannot act under it without the court's consent — a practical reason directors appoint an administrator.
• Deed of company arrangement. The moratorium ends. ASIC is explicit that a DOCA does not prevent a guarantee holder acting under it to be repaid.
• Small business restructuring. A creditor cannot enforce a guarantee against a director, spouse or relative for a company liability, except with leave of the court on any terms it imposes. The moratorium stops once the plan is made or the restructuring ends.
• Liquidation. No moratorium; guarantees are enforceable, and typically enforced.

The moratoria are pauses, not discharges. The options are set out in closing a company properly.

Reducing the exposure before it matters

Every reduction has to happen while the company is solvent and the creditor still wants the relationship. Once default is in sight the negotiating position is gone.

1. Cap and date every guarantee. Negotiate a stated maximum and an expiry or review date rather than an all-monies, perpetual instrument. Where a cap is refused, ask to carve out the family home.
2. Read the credit application. Trade credit forms routinely carry a guarantee clause above the signature block. Who may sign them should be a documented control.
3. Release on exit, in writing. Obtain a written release from each creditor, and treat an unreleased guarantee as live until it arrives.
4. Keep tax lodgements current even when payments cannot be made. Reporting PAYG withholding and GST within three months of the due date, and SGC by its due date, preserves remission options that late reporting destroys.
5. Pay employee entitlements and keep the books to the seven-year standard. Unpaid entitlements remove safe harbour and block a restructuring plan; poor records create a presumption of insolvency.
6. Review directors and officers insurance. Confirm what it covers, whether it responds after resignation, and whether run-off matches the limitation periods. It does not cover a guarantee.

Keeping a register of personal exposure

Most directors cannot list their own guarantees. A standing register, reviewed annually, is the highest-value control here. The minimum fields per instrument:

Add the statutory exposures to the same review: whether tax lodgements are current, whether superannuation guarantee has been paid by each quarterly due date, whether employee entitlements are current, and whether the ASIC register records the directors correctly. Track the dates in the compliance calendar and the contract register, and use /obligations to find which sector regimes add their own personal liability heads.
