Most Australian business owners know they have a credit score. Fewer realise they have two credit files, that business lenders usually read both, and that the two are governed by different rules.

This matters because a director with an immaculate personal file can still be declined on the strength of the commercial file, and a business with clean commercial conduct can be declined because of something on the director’s personal record. Understanding which file holds what is the first step to protecting both.

This guide explains what sits on each file, what damages them, how long the damage lasts, and what you can realistically do about it.

Quick Answer

Australian businesses have a commercial credit file held against their ABN or ACN, and directors have a separate personal credit file. Because directors almost always provide a personal guarantee on business finance, lenders typically assess both.

The fastest ways to improve and protect either file are the same: pay credit obligations on time every month, keep ATO lodgements current, avoid multiple credit applications in a short window, check all three bureaus at least quarterly, and correct genuine errors promptly. Accurate negative listings cannot be removed early, but their impact fades as recent positive history accumulates.

Your Two Credit Files

These are separate records, built from different data, and they behave differently.

FeaturePersonal credit fileCommercial credit file
Held againstYou as an individual, by name and date of birthYour business, by ABN or ACN
Governed byPrivacy Act 1988 and the Credit Reporting Privacy Code, with consumer protectionsPrivacy Act, but commercial credit information follows different rules and thresholds
Typical contentsCredit enquiries, repayment history on consumer accounts, defaults, court judgments, bankruptcyTrade payment behaviour, commercial defaults, court actions, ASIC data, disclosed ATO tax debts, adverse director history
Who reports to itBanks, lenders, telcos, utilities, buy now pay later providersSuppliers, trade creditors, commercial lenders, the ATO in defined circumstances
Why business lenders careDirectors almost always give a personal guarantee, so their conduct is relevantIt is the primary record of how the business itself pays its obligations

The practical implication: improving your business credit position means working on both files at once. Focusing on one while neglecting the other is how applications get declined for reasons owners find surprising.

The Three Bureaus and Why Your Score Differs

Australia has three credit reporting bureaus: Equifax, Experian and illion, the last of which was formerly Dun and Bradstreet. Each holds its own file on you, receives data from an overlapping but not identical set of providers, and applies its own scoring model.

BureauPersonal score rangeCommonly used by
Equifax0 to 1,200Most major banks and mainstream lenders
Experian0 to 1,000Many non-bank lenders and fintechs
illion0 to 1,000Telcos, utilities, and lenders drawing on commercial trade data

Because the scales and the underlying data differ, the same person can hold three different scores on the same day and all three can be correct. A telco default might appear with one bureau and not another. A gap of a hundred points or more between bureaus is common and is not evidence of an error.

This is the reason to check all three rather than relying on whichever free app you already have installed. A lender may pull the one you have not looked at.

What Damages Your Credit Position

In rough order of severity:

  • Default listings. For consumer credit, a provider can list a default where at least $150 has been overdue for 60 days or more and the required statutory notices have been sent. Commercial defaults follow different thresholds and procedures.
  • Court judgments and serious credit infringements. Both are treated as major adverse events by nearly every lender.
  • Disclosed ATO tax debt. Where a business has at least $100,000 overdue by more than 90 days and is not engaging with the ATO, the debt can be reported to credit reporting bureaus and appears on the commercial file. See our guide to ATO tax debt loans for how this works and how to avoid it.
  • Missed payments short of default. Under comprehensive credit reporting, monthly repayment history is recorded on consumer accounts. A pattern of late payments is visible even where nothing escalated to a default.
  • Clustered credit enquiries. Several applications in a short period read as shopping or distress, and can reduce your standing with the next lender in the queue.
  • Slow trade payment. On the commercial file, consistently paying suppliers beyond terms is recorded and visible to other suppliers and lenders.

The enquiry point deserves emphasis because it is the most avoidable and the most commonly self-inflicted. Applying directly to six lenders in a fortnight can leave you worse off than when you started, regardless of whether any of them approved you.

How Long Listings Stay

Retention periods are set by the Credit Reporting Privacy Code, not by the lender or the bureau. Approximate periods for personal credit files:

Listing typeHow long it staysClock starts from
Default5 yearsThe date it was listed, not the date you fell behind
Credit enquiry5 yearsThe date of the enquiry
Court judgment5 yearsThe date of judgment
Repayment history2 yearsRolling, month by month
Serious credit infringement7 yearsThe date it was listed

One point that catches people out: paying a listed default does not remove it. The status changes to a paid default, which lenders view considerably more favourably, but the entry remains for the full five years. Paying is still worth doing, both for that status change and because unpaid debts tend to escalate.

Retention rules for commercial credit information differ from the consumer periods above. The Office of the Australian Information Commissioner publishes the current requirements.

How to Improve Your Credit Position

There is no shortcut, but there is a reliable sequence.

  1. Pull all three files. Request your personal credit report from Equifax, Experian and illion, and order the commercial report for the business. You are entitled to a free copy of your personal report from each bureau every three months, and because lenders do not all use the same bureau, an error on one file may not appear on the others.
  2. Correct anything that is wrong. If a listing is inaccurate, out of date or was made without the required notices, ask the credit provider or the bureau to correct it. They must respond to a correction request, generally within 30 days, and if you are not satisfied you can escalate to the Australian Financial Complaints Authority (AFCA) or the OAIC.
  3. Pay or settle outstanding defaults. A paid default stays on file for the full retention period, but it is updated to show it has been paid, and most lenders read that more favourably. Get any settlement agreement in writing.
  4. Stop the run of applications. Every formal application leaves an enquiry, and several in a short period can lower your score and look like credit stress. Space out applications, and check your eligibility or speak to an introducer before applying.
  5. Make every repayment on time. Lenders can see up to two years of monthly repayment history on most consumer credit accounts, so a steady run of on-time payments does more to rebuild a file than anything else.
  6. Keep the business account clean. For business lending, conduct on the business bank account carries as much weight as the credit file. Avoid overdrawn days and dishonoured payments, and keep ATO lodgements current. If there is a tax debt, set up a payment plan early, because the ATO can report large overdue business tax debts to credit reporting bureaus.
  7. Reduce limits you do not use. Lenders assess credit limits, not balances, so an unused $20,000 credit card counts against your borrowing capacity as if it were fully drawn. Closing or reducing unused cards will not transform your score, but it can noticeably improve serviceability.

Corrections can take effect within weeks. Rebuilding a file through repayment history takes longer, usually several months of clean conduct before lenders treat it differently. If you are planning to borrow, it is worth reading about when to apply for a business loan so the timing works in your favour.

Common Questions

Does Checking My Own Credit Report Affect My Score?

No. Requesting your own report is not a credit application, and it is not visible to lenders as an enquiry. Only applications for credit are recorded as enquiries on your file.

Can I Get a Business Loan With a Default on My File?

Often, yes. Specialist and non-bank lenders will look past an older or paid default if current trading is strong and you can explain what happened. The options are narrower and usually cost more. Our guide to getting a business loan with bad credit covers what lenders accept, and our bad credit business loans page explains how we help.

How Long Does It Take to Improve a Credit Score?

An incorrect listing can be removed within about a month of a successful correction request. Improvements from paying down debt and making on-time repayments build gradually, so expect three to six months before the change is meaningful, and longer to recover from serious listings.
