Working for Families Overpayments: Why You May Have to Repay IRD

A Working for Families payment may arrive every week or fortnight and go towards ordinary household costs. Months later, you may receive a bill asking you to repay it. That can be unsettling when the original payments seemed correct.

An overpayment does not automatically mean fraud was involved or that Inland Revenue has imposed a penalty. Regular Working for Families payments are based on estimated income and family circumstances. After 31 March, the entitlement for that tax year is recalculated using the final information. The difference can be a refund or an overpayment bill.

Two questions lead to different responses. If the assessment uses the wrong income or family details, ask for those facts to be reviewed. If the debt is correct but paying it would be difficult, discuss repayment arrangements with Inland Revenue. The sections below explain how to establish which situation applies.

What the year-end reconciliation compares

New Zealand's standard income tax year runs from 1 April to 31 March. During the year, Inland Revenue generally pays Working for Families instalments based on the family's expected income, number of eligible children, work circumstances and care arrangements. The final calculation looks at the actual situation for the relevant periods.

The key comparison is between the amount of Working for Families already paid and the family's final entitlement. If instalments were too low, a balance may be refunded or applied against amounts owing. If they were too high, the difference becomes a debt. This is often referred to as the Working for Families square-up.

Inland Revenue explains that reconciliation on its end-of-year assessments page.

Understanding an NZ$780 repayment bill

Consider a family in Nelson that received NZ$9,360 in Working for Families instalments during a tax year. Once final income and care information was available, Inland Revenue calculated that the family's correct entitlement was NZ$8,580. The difference is NZ$780 (NZ$9,360 less NZ$8,580). That is the Working for Families overpayment in this simple illustration, before considering any adjustments or other tax balances.

The figures illustrate a reconciliation; they do not establish that a particular salary produces an NZ$8,580 entitlement. The entitlement itself depends on the types of credits, family scheme income, relevant rates, weeks of eligibility and changes in care. That separate calculation should be checked if the family's assessment appears wrong.

A Working for Families debt is not the same as extra income tax on wages or business profit. The two may appear in closely related myIR assessments, so first identify which balance is being charged and which tax year it concerns.

Why families are paid too much

The most common driver is an income estimate that turns out to be too low. A partner may start a new job, overtime may rise or a bonus may be paid. A sole trader may finish the year with higher net profit because sales increased or business expenses were lower than forecast. If instalments continue at the old estimated entitlement, the difference accumulates.

A household change can be just as important. Inland Revenue needs to know about a new partner or a separation, a change in shared care, a child leaving care, a dependent child becoming financially independent or a move overseas. Eligibility can also change if someone begins receiving a relevant government payment or stops meeting work conditions.

The Minimum Family Tax Credit needs particular care. Unlike the ordinary gradual abatement of the Family Tax Credit, this credit has a separate after-tax income limit and work conditions. If a household no longer meets them for a relevant period, a relatively modest change can remove some or all of that credit and lead to a substantial repayment. This is a reason not to estimate every Working for Families debt using the same 27.5% calculation.

Review Inland Revenue's Minimum Family Tax Credit rules and examples if that payment is included in your notice.

Assessment timing and repayment deadlines

Inland Revenue generally begins issuing end-of-year assessments from the last weekend in May and continues through June and July. For families with only income reported under PAYE or similar systems, it may already have most of the needed income information.

If a parent has self-employment, rental income or another source that requires an IR3 return, Inland Revenue generally prepares the assessment after that return is filed. The usual IR3 filing deadline is 7 July following the tax year. A valid tax-agent extension may allow filing by 31 March of the following year. If both partners must file IR3 returns, the family calculation may have to wait until both are completed.

For an overpayment relating to the tax year ending 31 March 2027, the usual payment deadline is 7 February 2028, or 7 April 2028 if the relevant tax-agent extension applies. A weekend or public holiday can affect the actual due date. Use the deadline shown on your Inland Revenue assessment; do not infer it from the day a message arrives in myIR.

Check whether the assessment is correct

Start with the tax year and the Working for Families amounts. Compare the total instalments recorded by Inland Revenue with the deposits shown in your bank and myIR transaction history. Next compare the final entitlement with the credits listed on the assessment: Family Tax Credit, In-work Tax Credit, Best Start and, where relevant, Minimum Family Tax Credit.

Check the income used for each parent or partner. If the family includes a sole trader, compare the IR3 business profit with the estimate used for Working for Families rather than relying on sales or drawings. Do the same for rent, other taxable earnings and any family-income adjustments. If one partner filed their IR3 late or their assessment was subsequently changed, ask whether the Working for Families calculation uses the updated information.

Finally, check the dates when a child was eligible, any shared-care percentage, when a relationship changed and any changes in residence or work hours. A wrong start or end date can affect entitlement even if the income figure itself is correct.

If a material fact is incorrect, correct the record or contact Inland Revenue through myIR and ask for the assessment to be reviewed. Do not assume an assessment is wrong simply because the final amount is lower than the initial estimate, and do not assume a dispute suspends a payment deadline unless Inland Revenue confirms it.

Check your assessment and discuss repayment options if a debt remains.

If the debt is right but you cannot pay it all

A genuine inability to pay does not automatically cancel a Working for Families debt. Inland Revenue provides instalment arrangements, including weekly or fortnightly repayments, which can be requested through myIR, by message or by phone. It may be possible to arrange for a specified amount to be deducted from future Working for Families entitlements.

In cases of financial difficulty, Inland Revenue may consider financial relief, which could include writing off some or all of a debt after reviewing the family's situation. That is not automatic and should not be presented as a guaranteed outcome. Contact Inland Revenue before the due date to discuss how you will deal with the balance.

Reduce the risk of another overpayment

If you choose weekly or fortnightly payments, keep the income estimate current. In myIR, open your Working for Families account, go to Family and income details and update income using what the family has already earned plus a reasonable forecast to 31 March. A revised estimate matters when a partner's salary changes, a contract is signed or a business profit forecast increases.

Some families with variable earnings prefer to receive the tax-year entitlement as a lump sum after 31 March. That avoids the usual risk of having to repay estimated instalments received during the year, although a later reassessment based on corrected information can still create a new balance. Choosing a lump sum also means going without regular cash-flow support during the year, so it is a financial decision rather than an automatic best choice.

IRD's income-update instructions and payment options explain how to make those changes.

A Working for Families bill is easier to deal with when the original income estimate, final taxable income, family changes and payment history can all be reconciled. Those records tell you whether the debt is correct and what must change before the next tax year.
