How to improve your business credit score, ranked by how fast each fix works

There’s no button that resets a business credit score, and anyone selling one is selling something else. What you can do is work through the things that actually feed the score, in the right order. Some take a phone call and fix the file inside a month. Others are habits that pay off over a year. The order matters because the quick fixes often unlock the slower ones.

If you haven’t yet seen your files, start with how to check your business credit score. Everything below assumes you know what’s on them.

What moves a business credit score?

Business bureaus each run their own models, but the inputs overlap heavily:

• Adverse listings: payment defaults, court judgments, ATO tax default listings, insolvency notices.
• Credit enquiries: how often, how recently and for how much the business has applied for credit.
• Payment behaviour: increasingly, how quickly the business pays its suppliers, drawn from trade and accounting data. CreditorWatch, for example, says its RiskScore draws on trade payment information including data from accounting platforms, and that invoices paid more than 14 days late can be reported.
• Company profile: age, entity type, ASIC status, registered details and director changes.
• People behind it: directors’ histories and other companies they’ve been involved with.

Some of those you can change this week, some this quarter, and some only with time.

Fixes that work in days or weeks

1. Correct genuine errors

This is the single fastest improvement, and it costs nothing. Common errors on business and director files include:

• defaults you’ve never heard of, or that belong to a similarly named business
• defaults already paid but still shown as unpaid
• enquiries you didn’t make, which can signal identity fraud
• directorships of companies you left years ago
• an old registered address that doesn’t match your application

On personal files, the rules are clear: lodge the request with the credit provider that listed the item or with the bureau. Once they accept the information is wrong, the amendment is due inside a 30-day window, unless you consent to extra time, and you get it in writing. For commercial files, the privacy principles also require accurate, up-to-date records, so the same approach works.

It’s also worth checking whether a default was listed properly. For a consumer default, the credit provider generally needs the debt to be at least $150 and 60 days overdue, and must have written to you twice beforehand, with a gap of 30 days or more between the first and second letters. A listing made without the required notices, or sent to an address the provider knew was out of date, may be challenged. The guide to removing a default from your credit file explains the process.

2. Engage with the ATO on any large tax debt

Three conditions let the ATO disclose a business tax debt to the bureaus: the overdue amount is $100k or higher, it has been unpaid past the 90-day mark, and the business hasn’t engaged with the tax office about it. The good news hides in that last condition. Entering a payment arrangement, and sticking to it, counts as engaging, and a listing must then be removed by the bureau.

A tax default listing is one of the heaviest marks a business file can carry, because it signals pressure from a creditor that has strong collection powers. Getting it off the file can shift a score more than months of good behaviour elsewhere. See ATO payment plans explained for how to set one up, and where the balance is beyond what instalments can handle, ATO tax debt business loans covers how some owners refinance it.

3. Update ASIC and ABN details

Ten minutes on ASIC’s register and ABN Lookup can tidy the identity data bureaus rely on. Make sure the registered office, principal place of business and officeholders are current, any former director is removed, and annual review fees are paid. Overdue ASIC obligations can show as notices on a business report and, in the worst case, lead to strike-off action.

Habits that work over one to six months

4. Pay suppliers on time, not just lenders

Owners often think of credit as loans and cards. Business scores increasingly weigh how you treat trade creditors too. A pattern of paying supplier invoices 30 or 45 days late, even when you always pay in the end, can drag a score down.

Practical moves:

• Set supplier payments to run automatically on the due date, not the day you remember.
• Negotiate longer terms upfront instead of stretching them unilaterally. Our guide to negotiating better supplier terms helps.
• Can’t meet a supplier’s due date? Ring them a few days ahead and confirm a revised date by email. A documented arrangement is different from a missed payment.

5. Cut back on applications

Each credit application sits on file as an enquiry for five years, recording the provider and often the amount. A run of enquiries close together reads as a business under cash pressure, even when it’s really an owner shopping around.

So be deliberate. Don’t apply for a card just to “build credit”, don’t fill in five lender forms the same afternoon, and use an enquiry service that doesn’t run a credit check until you’re ready to proceed with a specific lender. Our explainer on whether applying for a business loan affects your credit score covers this in detail.

Not sure which lender is likely to say yes? Ask us first; a quick enquiry adds nothing to your company’s file or your own.

6. Protect each director’s personal file

For small companies, lenders rarely separate the business from the people running it. Directors almost always guarantee, so their personal files are checked. On a personal file:

• Each month’s repayment status is kept for two years, and anything paid beyond 14 days after the due date is logged as missed. Set up direct debits for every personal loan, card and home loan.
• If you’re struggling with a personal repayment, ask for a hardship arrangement early. A default generally can’t be listed while a hardship request is being considered.
• Lower or close unused card limits. They don’t hurt a score directly, but lenders count the limits as commitments.

Our page on how business loans and personal credit connect maps how the two sides interact.

Things that only time fixes

Some parts of the score can’t be hurried. On personal files, a default or court judgment remains for five years; a serious credit infringement remains for seven. Credit enquiries also stay for five years. Business age is just that: a company registered last year can’t be three years old.

But their effect fades. A two-year-old paid default sitting among 24 months of clean repayments reads very differently from a fresh one. Lenders, especially non-banks, weigh the recent pattern more heavily than the old mark.

A 90-day plan you can start this week

When	What to do	Why
Days 1–7	Pull directors’ personal reports and a business report; check ASIC and ABN details	Know exactly what lenders will see
Days 1–14	Dispute any errors in writing, keep copies	Accepted corrections must be made within 30 days
Days 1–14	Call the ATO about any overdue debt; set up a payment plan	Stops or removes a tax default listing
Days 7–30	Automate supplier and personal repayments; renegotiate terms you can’t meet	Builds the on-time pattern scores reward
Days 30–90	No new credit applications unless essential; reduce unused card limits	Lets the enquiry pattern settle
Day 90	Re-check the files	Confirm corrections and listings have updated

An illustration: one Townsville wholesaler’s quarter

This is a made-up example. A Townsville food wholesaler with a $1.6m turnover is declined by its bank for a $200k trade facility. The owner pulls the reports and finds four things: an ATO tax default listing for $118k of overdue GST, two credit enquiries from online lenders in the same week, a $3,400 default from a packaging supplier, and his personal file still listing him as director of a café he sold in 2019.

In week one he agrees a payment plan with the ATO. Within a few weeks the tax listing is gone from his business file. The packaging default turns out to be valid but paid, so he asks the supplier to update it to “paid”. The café directorship is an ASIC record that was never updated by the buyer’s accountant; fixing it takes a form and a fortnight.

Three months on, the business file shows a paid default, two older enquiries and an ATO plan being kept. The bank still wants more time. A non-bank trade finance lender, shown the plan and six months of strong deposits, approves a smaller facility to start.

What doesn’t work

• Credit repair firms that promise removal of accurate listings. No-one can lawfully do that. You can dispute errors yourself at no cost.
• Opening new accounts to “build history”. Each one adds an enquiry and a commitment.
• Changing the business structure to escape a bad file. Lenders look at directors and related entities, and phoenix-style restructures attract scrutiny, not approvals.
• Waiting for the perfect score before applying. Lenders who work with imperfect files read the story, not just the number.

Improving, but still need finance now?

A better score widens your choices and usually lowers what finance costs. But business doesn’t always wait for a clean file. A tax plan in progress, a paid default or a cluster of enquiries is a situation we see every week, and it doesn’t rule you out with the right lender.

Our enquiry takes about a minute, and sending it doesn’t record a credit enquiry anywhere. Your enquiry stays with our team instead of being forwarded to a string of funders, so there’s no barrage of calls. A person reads it, weighs what you’ve told us about your file and calls you to talk options through. Spell out what’s on your file and what you’ve already fixed, so the lender we suggest is one that welcomes a business on the way up.
