Minimum family tax credit

For Income Related Rent purposes, the minimum family tax credit applicable people are entitled to get is included as assessable income.

Minimum family tax credit is a payment made to families with dependent children aged 18 or younger, so they have a minimum income each week after tax.

Generally, the assessment to estimate the minimum family tax credit is as follows:

  • determine if the applicable people are entitled to get a minimum family tax credit
  • determine their estimated after-tax annual income for wages and salary
  • work out the annual rate they would be entitled to get from the minimum family tax credits - to do this:
    • get the current Inland Revenue threshold for minimum family tax credit
    • subtract the annual income from the threshold rate
    • include this amount in the assessable income

Example of estimating minimum family tax credit

Rena is a sole parent with one child aged 14 years. She works 23 hours per week and earns $23,411.96 (net) per year, ($450.23 (net) per week).

Rena can get a minimum family tax credit to top up her net income to $703.00 per week (at 1 April 2026).

Calculate the minimum family tax credit to include as assessable income as follows:

Determine the amount to include as assessable income

Inland Revenue after tax threshold for minimum family tax credit (at 1 April 2026)

$36,604.00 = A

Less client's annual income (after tax)

$23,411.96 = B

Annual entitlement to minimum family tax credit (= A minus B)

$13,192.04 = C

Weekly entitlement (C divided by 52)

$253.69 = weekly amount to include in assessable income
