Child Support Income for a Home Loan

Child support can count as income for a home loan when the lender accepts the arrangement behind it. That usually means a Services Australia assessment, a registered agreement or a court order, bank statements showing the payments arriving and enough years left before the support ends.

The same payments can count in full at one lender and not at all at another. Macquarie’s 10 September 2026 credit guidelines accept child support only when the child is under 11. Pepper Money’s 21 August 2026 product guide sets no age limit but needs five more years of payments for its Prime home loans.

Establish the Payment Arrangement

Start by identifying which of four arrangements sets the payments, because each one leaves a different paper trail. Macquarie’s 10 September 2026 guidelines and Pepper Money’s 21 August 2026 guide still use the name Child Support Agency, which is now Child Support at Services Australia.

Arrangement	Who sets the amount	Records your client can supply
Child support assessment	Services Australia, using the formula in Australian law	Assessment letters from the myGov Inbox, plus the online account’s due dates, amounts and past payments
Child support agreement	The parents, in a limited or binding agreement that Services Australia accepts	The signed agreement and the acceptance letter. A binding agreement also needs independent legal advice for both parents
Court order	A court with family law jurisdiction	A copy of the order and, where it’s registered with Child Support, the registration records
Self-managed arrangement	The parents, without an assessment	Bank statements and any written arrangement between the parents

A self-managed arrangement gives the lender the least to work with. Macquarie needs a registered agreement or a court order, while Pepper Money also accepts three months of continuous payments in the statements.

How the money moves matters as much as who set the amount. Under Child Support Collect, Services Australia collects from the paying parent and transfers to your client on or after the 8th of each month. Under Private Collect, the parents pay each other directly and keep their own records.

An agreement can cover non-cash items, such as school fees and health insurance. Under Private Collect, the parents can also agree to send part of the payment to a third party. Neither shows up as a credit in your client’s account, so a lender reading bank statements won’t see it.

A court order can cover a child that the child support legislation doesn’t, including maintenance for a child over 18. Services Australia’s page on court ordered periodic child maintenance says parents must notify it within 14 days of an order.

Worked Example: Assessed Amount Against Bank Receipts

This fictional example compares an assessment with six months of bank statements. Nina is a single parent with one child aged 12, who turns 18 in March 2032. A Services Australia assessment sets $1,150 a month in child support, which the other parent pays through Private Collect.

Month (2026)	Assessed	Credited to Nina’s account	What the statement shows
April	$1,150	$1,150	Transfer referenced “child support April”
May	$1,150	$1,450	$1,150 of support plus a separate $300 transfer referenced “school camp”
June	$1,150	$0	Missed payment
July	$1,150	$2,300	July’s payment plus June’s missed payment
August	$1,150	$550	The other parent paid the remaining $600 straight to the school
September	$1,150	$1,150	Transfer referenced “child support September”
Total	$6,900	$6,600	$6,300 of support credits once the $300 camp transfer is removed

The statements show $6,300 of support against $6,900 assessed. The $300 camp transfer is a one-off private payment outside the assessment, so it isn’t support income. The $600 school payment may satisfy the parents’ informal arrangement, but it never reached Nina’s account.

Two dates can change the amount. An assessment period lasts up to 15 months, and a new one can start when the Australian Taxation Office (ATO) passes on a parent’s income for a new financial year. Support for this child normally ends in March 2032, when the child turns 18.

Verify Receipt and Duration

Match each payment the arrangement requires to a credit in your client’s bank statements, then measure how long the support has left against the child’s age. Use the client’s own account statements, because they show what actually arrived rather than what was owed.

Check four things on each statement line.

1. The amount matches the assessment, agreement or order.
2. The payer and reference identify the payment as child support.
3. Missed or partial payments are explained, such as June’s catch-up in July.
4. One-off transfers, such as the $300 camp payment, are left out.

Child support usually stops when the child turns 18. Services Australia can extend it to the end of the school year, but only after an application made while the child is 17.

Count the remaining period to the 18th birthday, because an extension isn’t certain until Services Australia approves it. On that basis, Nina’s support has five years and five months left.

Lender Rules for Child Support Income

Lenders set different limits on the child’s age, the months of receipts and the years left. Macquarie and Pepper Money count accepted child support at 100%.

Lender	Documents	Payment history	Age or remaining period
Macquarie, 10 September 2026 guidelines	Agreement registered with Child Support, or a court order with payments in line with it	Six months of consistent payments in the borrower’s bank statements	Child under 11 at application. Support can’t be the only income
Pepper Money, 21 August 2026 product guide	Court order, agency agreement or agency letter	Three months of continuous payments in savings statements, as an alternative to the documents	No age limit. Prime home loans need five more years of payments
Bluestone, quick policy guide last updated 10 November 2025	Agency letter confirming the amount and how long it runs	At least one credit in the bank statements	Refer to a business development manager (BDM)

Applied to Nina, the rules give three different answers.

• Macquarie’s guidelines don’t count the support, because the child is 12. The missed June payment would also need explaining against its six-month consistency rule.
• Pepper Money’s guide accepts three months of continuous payments in savings statements, and Nina’s statements show support credits in July, August and September. Five years and five months remain, which meets its five-year rule for Prime home loans.
• Bluestone’s policy guide needs the agency letter and at least one credit. Nina’s assessment letter and April credit meet both, and the guide refers the case to a BDM.

Pepper Money’s non-conforming loans accept support with less than five years left, but only if your client can still service the loan once the payments stop. Bulma’s Policy Advisor compares child support rules across 52+ lenders in one question and quotes each lender’s policy wording for your file notes.

Support Income and the Child’s Costs

The remaining period limits the income, but the child’s costs stay in the servicing test for as long as the child lives with your client. Excluding the support doesn’t remove the child from the household. Macquarie’s broker help page, as at October 2026, tells brokers to declare the dependant when a client has custody but pays no child support.

The dependant changes the expense figure the lender uses. Macquarie’s serviceability calculator builds the Household Expenditure Measure (HEM), a benchmark of household living costs, from the applicants’ details, including dependants and income. It then uses the higher of the declared general living expenses and HEM.

Income with an end date during the loan also has a regulatory side. The Australian Securities and Investments Commission (ASIC) lists child support as income that depends on a third party in Regulatory Guide 209 (RG 209). RG 209 also expects lenders and brokers to consider the effect of income that stops during the loan term.

Model Acceptance and Exclusion

Run the borrowing assessment twice, once with the accepted child support and once without it, and keep the child’s living costs in both runs. The gap between the two figures shows how much of the loan depends on the support. The loan serviceability guide explains the full income and expense test.

This simplified model uses Nina’s fictional figures. It assumes take-home pay of $5,900 a month, a car loan repayment of $450 a month and living expenses of $3,200 a month for one adult and one child. It also assumes a lender accepts the $1,150 assessed amount, tests repayments at 8.5% over 30 years and treats the whole surplus as available for repayments.

Monthly item	With child support	Without child support
Take-home pay	$5,900	$5,900
Accepted child support	$1,150	$0
Living expenses for one adult and one child	-$3,200	-$3,200
Car loan repayment	-$450	-$450
Surplus for loan repayments	$3,400	$2,250
Approximate borrowing power	$442,200	$292,600

The accepted support adds about $149,600 to Nina’s borrowing power in this model. If she applies for $400,000, the loan only works where a lender accepts the support, such as Pepper Money’s Prime home loans under its 21 August 2026 guide. Real lenders also apply their own buffers, minimum surplus rules and income treatment, so their figures will differ.

The common mistake is to remove the child’s costs along with the child’s support.

• Incorrect: excluding the support and also dropping the child’s costs to $2,500 a month leaves a $2,950 surplus and about $383,700 of borrowing power.
• Correct: excluding the support while keeping the $3,200 of costs gives the $292,600 in the table.

The incorrect version overstates Nina’s borrowing power by about $91,100, because the child still lives with her and still costs money.

Write the Lender Submission Note

Write a short note that separates what the statements prove, what is expected to continue and what remains unresolved. This fictional note covers Nina’s file.

Child support: Services Australia assessment of $1,150 a month for one child aged 12, paid by Private Collect. The assessment letter is attached.

Documented receipt: statements from April to September 2026 show $6,300 of child support transfers. The June payment was missed and paid in July. A $300 transfer in May for a school camp is excluded as a one-off.

Expected continuity: support for this child normally ends in March 2032, when the child turns 18, five years and five months from application. The amount can change when a new assessment period starts. Without the support, the servicing model supports a loan of about $292,600, so this $400,000 application relies on the support being accepted.

Unresolved: in August, the other parent paid $600 directly to the school under an informal arrangement. It isn’t counted as income.

Keep legal entitlement questions out of the note. Whether the $600 school payment counts toward the assessment is for Services Australia or a family lawyer to answer. If the client is also refinancing after separation or removing a former partner from the loan, the divorce mortgage guide covers those steps.

Submit the support as income only where the lender’s rules on documents, payment history and remaining period all fit the file. Where they don’t, the application has to stand on the without-support figure, with the child’s costs still counted.
