Business credit score

A business credit score rates your company or ABN, separate from your personal score. What feeds it, how ATO debt listings hit it, and how lenders weigh it.

Quick answer

A business credit score is a rating a commercial credit bureau gives a company or ABN to predict how likely it is to fail to pay its debts, usually over the next twelve months. It's separate from the directors' personal scores. Bureaus such as Equifax, illion, Experian and CreditorWatch each use their own scale and data, drawing on trade payment records, court actions, defaults, company details and, in some cases, ATO tax debt disclosures.

Key points

  • Rates the business entity, not the owner, though lenders usually check both
  • Each bureau uses its own scale, so scores can't be compared directly
  • Business tax debts of $100k+ overdue more than 90 days can be reported to bureaus
  • Commercial credit information falls under the Australian Privacy Principles

Your company has a credit reputation of its own. Put simply, a business credit score is a commercial bureau’s estimate, boiled down to one figure, of how likely a company, trust or ABN is to default on what it owes, typically over the coming year. It sits alongside, not instead of, the personal credit score attached to each director.

Who produces business credit scores in Australia?

Data on Australian businesses is held by a handful of commercial bureaus: Equifax, illion, Experian and CreditorWatch. Each runs its own model, so the same company can rate well with one and middling with another.

The scales differ too. CreditorWatch, for example, says its RiskScore runs from 0 to 850, with businesses also placed in one of 14 letter ratings from A1 down to F, and that the score predicts the likelihood of default over the following twelve months. Other bureaus use different ranges and bands, which is why comparing a number from one provider with a number from another tells you very little.

What feeds the score?

Input Why it matters
Trade payment data Suppliers who share records show whether you pay on time
Credit enquiries A burst of applications suggests cash pressure
Defaults and court actions Unpaid debts and judgments weigh heavily
Company details Age of the business, ASIC status, director changes
Tax debt disclosures ATO listings of large overdue debts
Directors’ records Some models factor in directors’ histories and other companies they’ve run

Commercial credit information works under a different set of privacy rules from the consumer system. The OAIC explains that the Australian Privacy Principles let organisations use it for purposes such as assessing a commercial credit application, and require them to keep it accurate and up to date.

How does ATO debt show up?

This is one of the most practical details for owners to understand. Under its disclosure rules, the ATO may tell the bureaus about an unpaid business tax debt once it reaches $100,000, has been overdue for longer than 90 days, and the owners aren’t dealing with the ATO about it. The ATO must write to the business first and allow 28 days to respond. Entering a payment plan or paying the debt stops the disclosure, and the bureau must remove a listing once the business engages. If a notice has arrived, our page on ATO tax debt business loans covers the options.

How do lenders use it?

Banks often treat a weak business score as a stop sign. Non-bank and fintech lenders are more likely to read it alongside recent bank statements, which can outweigh an old blemish if trading is steady. Property-secured lenders lean more on the equity and the exit plan.

An illustration. A Brisbane fit-out company has directors with clean personal files, but its business score has slipped after a supplier listed a disputed $14k invoice as a default. The bank declines. A non-bank lender asks for the dispute correspondence, sees six months of healthy deposits, and approves a smaller unsecured facility while the director works to have the listing corrected.

Worried your score will hold you back?

A patchy business score narrows the field, but it rarely closes every door. It’s a one-minute form, and completing it puts no enquiry on either your company’s file or your own. Nothing gets fired off to a dozen funders at once; a single specialist reads your answers and phones to work out a sensible next step. Be upfront about any defaults or tax debts on the form, because that lets us steer you to lenders who are comfortable with them from day one.

Frequently asked questions

Is my business credit score linked to my personal credit score?

They're calculated separately, but for small businesses lenders almost always look at both. Directors' personal histories can also feed into some commercial scores, and a personal guarantee links your personal credit to the business loan.

How do I check my business credit score?

Commercial bureaus sell business credit reports and scores, and some offer free or trial access for your own entity. Because each bureau holds different data, it's worth checking more than one before a major application.

Can an ATO debt hurt my business credit score?

It can. The ATO may disclose a business tax debt to credit reporting bureaus when it's at least $100,000, more than 90 days overdue, and the business isn't engaging with the ATO. It must give written notice first, and entering a payment plan or paying the debt prevents or removes the listing.

Does a sole trader have a business credit score?

A sole trader's ABN can appear in commercial bureau records, but because a sole trader is the business, lenders lean heavily on the owner's personal credit file. Companies and trusts are more likely to have a meaningful separate business score.

What lowers a business credit score fastest?

Defaults and court judgments, a cluster of new credit enquiries, slow payment to suppliers who report to bureaus, and an ATO debt disclosure. Late lodgement of company details with ASIC can also count against you with some bureaus.
