An overdue tax balance can now create a problem beyond penalties, interest, and collection calls: it may become visible to a credit reporting agency. For a New Zealand business, that can change how a lender, supplier, or other credit provider views an application—even when the business is otherwise trading normally.
Inland Revenue has updated how it shares information about significant unpaid tax. The change does not mean every late GST return automatically appears on a credit file. It does mean that a large or long-running debt, combined with collection steps and formal notice, has a defined route into the credit-reporting system.
This guide explains the thresholds, what to watch in myIR, how to respond to a Notice of Intent, and which bookkeeping controls can help you avoid being surprised.
When can Inland Revenue credit-report a business?
The current published criteria describe two alternative debt tests. A business may be considered for credit reporting when it has:
- GST, PAYE, or income-tax debt over NZ$150,000 that is at least 90 days overdue; or
- tax debt that has been unpaid for more than 12 months and equals at least 30% of the taxpayer’s assessable income.
Meeting one of those tests is not, by itself, the whole process. Inland Revenue must also have made reasonable efforts to collect the debt and formally notify the business at least 30 days before the information is reported.
The scheme is aimed at significant tax debt, not an ordinary late payment that is corrected quickly. The legal form of the taxpayer also matters: official policy material describes the existing ability as limited to companies, while the operational guidance uses “business” language. If you operate as a sole trader, partnership, trust, or another structure, confirm how the rules apply to your entity with Inland Revenue or a New Zealand tax adviser rather than assuming the company criteria apply to you.
The NZ$150,000 test is a debt threshold, not a cash-flow target
The first test looks at the amount of reportable unpaid tax and how long it has been overdue. Add together the relevant overdue tax exposure shown in your records, then compare it with the balance in myIR. Do not rely on a bank balance or an estimate from an old GST return: payments, credits, reassessments, penalties, and interest can change the amount that remains unpaid.
The second test catches a different pattern. A smaller nominal balance can still be significant if it has been unpaid for more than a year and represents at least 30% of assessable income. That makes an apparently manageable balance worth monitoring even when it is well below NZ$150,000.
What changed in 2026?
The important change is procedural. Inland Revenue says reasonable collection effort is now met when it has sent at least two automated overdue tax notices to the company, including notices sent through myIR. Direct personal contact with the customer is no longer required for this part of the test. Conversations with a company director or tax agent can satisfy the contact requirement when contact is made, but you should not assume that a missed phone call pauses the process.
The formal warning has also become easier to deliver. From 1 April 2026, Inland Revenue can issue the 30-day Notice of Intent through myIR or standard post. It no longer needs to courier the notice to every director.
The notice is not automatically redirected to a tax agent. If your adviser has the customer master link, they may be able to view the letter in myIR, but the business remains responsible for checking its own account and acting within the notice period.
Inland Revenue has also said it is seeking to extend this information sharing to other approved credit reporting agencies. That makes it even more important to treat the notice and the underlying debt as an active financial-control issue, not as correspondence that can wait for the next annual review.
What does a credit report mean for the business?
A credit report gives a credit provider information it may use when assessing risk. If tax-debt information is shared, a lender or trade-credit provider may consider it alongside the business’s other financial information. Possible effects include more questions, tighter terms, a request for security, a lower facility, or a slower approval process. The actual effect depends on the provider, the business’s financial position, the size and age of the debt, and whether the balance has been resolved.
Credit reporting is not the same as a public announcement, and it does not decide an application automatically. It is a data point in a credit assessment. But the timing matters: an unresolved tax balance can become visible just when you are seeking a working-capital facility, negotiating supplier terms, renewing an overdraft, or applying for equipment finance.
Keep the business’s information accurate. The Office of the Privacy Commissioner explains that New Zealand credit reporting is governed by the Credit Reporting Privacy Code, which includes rules about what credit reporters may collect, who may access reports, and how long information may be disclosed. If you believe a report contains inaccurate information, raise the issue with the credit reporter and ask how the information was obtained and what correction process applies.
The first control: make myIR part of your close process
An email inbox is not a reliable tax-control system. Notices can be missed when a director changes, an employee leaves, a tax agent’s authority changes, or a business assumes that every myIR message will be forwarded automatically.
Assign a named person to review myIR on a fixed schedule. At minimum, that review should confirm:
- new messages, overdue notices, and payment reminders;
- GST, PAYE, and income-tax balances by period;
- upcoming filing and payment due dates;
- payments that have been made but are not yet reflected;
- active instalment arrangements and their next payment dates; and
- whether the business and its adviser still have the access needed to see the relevant accounts.
Save the date of the review and the action taken. A short control note such as “reviewed 31 August; GST July payment matched; no overdue PAYE” creates a much better handoff than a vague statement that someone “checked IRD.”
The second control: reconcile the tax types separately
Tax debt often becomes difficult to manage because several obligations are blended into one number. Keep separate schedules for GST, PAYE and employer deductions, provisional or terminal income tax, penalties, interest, credits, and payments in transit.
For GST, reconcile the filed return to the sales and purchase records that produced it. For PAYE, compare the payroll register and payday filings with the amount paid to Inland Revenue. For income tax, distinguish the current assessment from provisional-tax instalments and any prior-period balance.
This separation helps you answer practical questions quickly:
- Is the balance a genuine cash shortfall, or has a payment or credit been misapplied?
- Is a return missing, so the account cannot yet be assessed correctly?
- Is the business collecting GST or PAYE from others but using it for operating expenses?
- Which tax type should be addressed first to stop the balance from growing?
Book each payment against the correct tax type and period, then match the ledger to the myIR statement. A balance-sheet account for GST payable and a separate liability for PAYE withheld can make the risk visible before it becomes a large year-end surprise. Keep supporting returns, payment confirmations, and messages with the period they relate to.
What to do when you receive a Notice of Intent
Treat the 30-day period as a deadline for a documented response. Do not wait for a collection call or assume that a part-payment will stop credit reporting automatically.
1. Confirm the notice and the balance
Read the notice in myIR or the mailed copy and compare its amount, tax types, and periods with your own reconciliation. Check whether any return, payment, credit, or reassessment is missing. If the amount is wrong, gather the evidence immediately and contact Inland Revenue through an approved channel.
2. File overdue returns
An unfiled return can make the account harder to understand and can prevent a realistic payment proposal. Complete the outstanding filings or ask your adviser to confirm what is missing. Keep copies of the submitted returns and submission confirmations.
3. Pay or request an arrangement
If you can clear the balance, confirm how and when the payment will be applied. If you cannot, apply for an instalment arrangement rather than making informal payments and assuming they are enough. Inland Revenue says agreed regular instalments can reduce the penalties you pay; simply sending occasional payments without an agreed arrangement may leave penalties and interest accruing at the full rate.
For a larger business debt, be ready to explain the proposal with a cash-flow forecast, profit-and-loss information, assets and liabilities, payment frequency, and the reason the arrangement is achievable. The figures should agree with your bookkeeping records. An optimistic payment plan supported by no cash-flow evidence is less useful than a smaller plan you can actually maintain.
4. Document the response
Record the person who contacted Inland Revenue, the date, the reference or message, the proposed action, and the next review date. If you enter an arrangement, calendar every instalment and continue filing new returns on time. A payment plan does not replace the obligation to keep current tax filings and payments under control.
A practical 30-day response checklist
Use this sequence when a Notice of Intent arrives:
Days 1–5: establish the facts
Download or save the notice, export the relevant myIR statements, and reconcile each tax type to your ledger. Identify missing returns, disputed items, payments in transit, and the cash available for an immediate payment.
Days 6–10: prepare options
Build a 12-month cash-flow forecast. Separate tax payments from rent, wages, suppliers, and financing. Model a full-payment option and one or more realistic instalment options. Include new GST, PAYE, and income-tax obligations that will fall due while the old balance is being repaid.
Days 11–20: communicate and apply
Contact Inland Revenue or submit the relevant myIR request with the supporting information. Ask specific questions about how payments will be allocated and what will happen to penalties and interest. Keep the response receipt and any counterproposal.
Days 21–30: close the loop
Confirm that the agreed action is recorded, set up payment reminders or direct debit where appropriate, and assign an owner for weekly monitoring until the balance is stable. If credit reporting has already occurred, ask what updates will be made after the debt is paid or an arrangement is accepted; do not assume every agency updates at the same speed.
Mistakes that make tax debt worse
Treating a notice as an administrative problem
The notice is also a signal about liquidity, reporting discipline, and access control. Escalate it to the owner and the person responsible for cash forecasting.
Paying the total without checking the periods
A large payment can be misapplied if the tax type or period is wrong. Match the payment confirmation to the myIR account and retain the evidence.
Using GST or PAYE collections as working capital
Those amounts may sit in the bank account, but they are not ordinary operating revenue. Track them as liabilities and reserve cash for the due date.
Assuming the tax agent owns the deadline
An adviser can help prepare returns and negotiate an arrangement, but the business should maintain its own myIR access, notice review, and calendar. Make sure authority changes are reflected promptly.
Hiding the problem from lenders and suppliers
If a credit application asks about tax debt or payment arrangements, answer accurately and explain the corrective plan. A reconciled balance, current filings, and a maintained arrangement provide better evidence than an unexplained late disclosure.
Build the control before the debt is large
The most useful response is a repeatable monthly process: reconcile tax accounts, review myIR notices, forecast the next 90 days of GST and PAYE cash needs, and escalate any balance that is aging or growing. Add a quarterly access review so that the owner, bookkeeper, and tax adviser can see the right accounts and receive the right alerts.
Keep a simple tax-debt register with the tax type, period, original due date, current balance, last payment, next action, owner, and supporting document. That register turns a stressful letter into a trackable work item and gives your adviser the facts needed to help.
This is general information, not advice for a particular business. Thresholds, entity rules, and collection decisions can change, so confirm your situation with Inland Revenue or a qualified New Zealand tax adviser.
