This New Zealand calculator helps working families on lower incomes estimate the Minimum Family Tax Credit, a top-up designed to ensure families in paid work have a guaranteed minimum income after tax. You enter your family situation and income, and the tool estimates whether you may qualify and roughly what the top-up could be, helping families understand a support payment that is often overlooked. Because the thresholds and amounts are set by the government and change over time, the calculator is built to use current figures rather than hard-coding them, and it points you to check the latest rules. The breakdown shows your after-tax income, the guaranteed minimum, and the estimated top-up, giving working families clearer insight into the support available alongside Working for Families.
The guaranteed minimum income and the required work hours are set by Inland Revenue and change over time, so enter the current figures and confirm eligibility. The credit is generally for working families not receiving a main benefit. Estimate only, general information, not financial or tax advice.
The Minimum Family Tax Credit guarantees that a working family after-tax income does not fall below a set level. The calculator compares your family after-tax income with that guaranteed minimum. If your income is below the minimum, the top-up is the difference, lifting you up to the guaranteed level. If your income is already at or above the minimum, no top-up is payable. It also checks the work-hours requirement, since the credit is for families in paid work.
If the guaranteed minimum after-tax income is $35,316 a year and a family earns $32,000 after tax while meeting the work-hours test, the top-up is $3,316 for the year, or about $64 a week, bringing them up to the guaranteed level.
