Moving Back Home as an Adult: What to Pay Parents

By The Chipkie Team, Personal Finance Editorial Team  ·  Last updated 16 August 2026

Rent is up, deposits are further away than ever, and a spare bedroom at Mum and Dad’s has become one of the most powerful savings tools in the country. Moving back home as an adult is no longer a sign of failure — it’s a deliberate financial strategy for hundreds of thousands of Australians. But the arrangement only works when the money side is spoken about out loud, early, and preferably in writing.

The trouble is that most families never do this. Vague guilt replaces a number, resentment builds over who bought the milk, and nobody knows whether the cash flowing between generations is a contribution, a gift or a loan. Those three words carry very different legal, Centrelink and mortgage consequences.

Key Takeaways

• A fair household contribution is usually a below-market figure that covers your marginal cost to the household — the extra food, power, water and car use you actually create — not a commercial rent.
• Australia has no gift tax and no inheritance tax, so parents can gift money freely; the ATO does not tax genuine gifts between family members.
• If a parent receives the Age Pension or another means-tested payment, gifting is limited to $10,000 per financial year and $30,000 over five financial years before the excess is treated as a deprived asset for five years.
• Australian lenders require a signed gift letter or statutory declaration confirming a deposit gift is non-repayable — signing one when repayment is genuinely expected is fraud.
• Money your parents lend you is a liability, not a deposit source, and must be disclosed on a home loan application.

How much should an adult child contribute at home?

Most Australian families land between $100 and $250 per week for board, covering food, utilities and general household costs. The right figure is the extra cost you genuinely add to the household, plus a modest amount toward the mortgage or rates — not market rent. Price it too low and resentment grows; price it too high and the whole point of moving home evaporates.

A practical way to build the number from the ground up:

1. Groceries: take the household food spend before you moved in, compare it to now, and take responsibility for the difference.
2. Utilities: compare a current electricity, gas and water bill against the same quarter last year. Splitting utilities and groceries with parents works best on actual bills, not guesswork.
3. Car and transport: if you use a parent’s car, contribute to fuel, and check with the insurer whether you need to be listed as a named driver.
4. Housing component: a token amount toward rates, insurance and wear and tear. This is where families should be honest that it is deliberately below market.
5. Savings commitment: agree a fixed amount that goes straight to your deposit account each payday. This is the entire justification for the discount.

Our experience across family arrangements is that the households that work best make the discount explicit. Saying “market rent for this room is $320, you’re paying $150, and the $170 difference is our contribution to your deposit” converts an unspoken favour into something both sides can see and value.

Does a parent have to declare board as rental income?

Generally no. The ATO treats payments from a family member living at home under a genuine domestic arrangement as non-assessable, meaning the parent does not declare the income and cannot claim deductions against it. If the arrangement becomes commercial — a market rent under a formal tenancy — different rules apply, including possible capital gains tax consequences on the main residence.

This is worth understanding before parents “do the right thing” and charge full market rent. Charging a commercial rate to a boarder can compromise part of the main residence capital gains tax exemption on eventual sale. Check the current position on the Australian Taxation Office website or with an accountant before formalising anything commercial.

What should go in a household contribution agreement with parents?

A household contribution agreement is a short written document setting out the weekly amount, what it covers, how bills are split, house rules, and — critically — an exit date. It does not need to be a legal contract. Its purpose is to remove ambiguity, prevent drift, and give everyone a scheduled moment to renegotiate rather than argue.

Cover these points:

• The amount and payment date — a standing transfer on payday, never cash handed over sporadically.
• What is included — food, power, internet, laundry, car use; and what is not.
• Bill splitting method — a fixed share, or a percentage of each quarterly bill.
• Non-financial contributions — cooking two nights a week, mowing, driving grandparents to appointments. These are real and should be named.
• Guests, noise and shared spaces — the practical friction points that sink arrangements.
• An exit date and a review date — for example, “reviewed every six months, target move-out December 2027 or on reaching a $90,000 deposit, whichever comes first.”
• What happens if you lose your job — agree the fallback now, not in a crisis.

If you want a deeper framework for the conversation itself, our guide to setting financial boundaries with family covers how to raise money topics without triggering a fight.

Is the money moving between you a contribution, a gift or a loan?

A contribution is payment for value received — board and food. A gift is money handed over permanently with no repayment expected. A loan is money that must be repaid. These are legally and practically different, and the distinction becomes critical the moment you apply for a home loan.

Australia has no gift tax and no inheritance tax, so parents gifting a deposit face no tax bill on the transfer itself. The real constraint is social security. If a parent receives the Age Pension or another means-tested payment, gifting is capped at $10,000 in a single financial year and $30,000 across five financial years. Anything above that is counted as a deprived asset for five years and continues to reduce their payment. ASIC’s MoneySmart explains how deeming and the assets test interact with these rules.

Can money from your parents actually be used for a home deposit?

Only if it is a genuine gift. Australian lenders require a signed gift letter or statutory declaration confirming the funds are non-repayable, and most want the money seasoned in your account for a period as part of their genuine savings test. An informal family loan is not an acceptable deposit source — it must be disclosed and will be assessed as a debt against your borrowing capacity.

This is the point where families get into serious trouble. A parent says “it’s a gift, but pay us back when you can.” That is a loan. Signing a lender’s gift letter or a statutory declaration saying the funds are non-repayable when repayment is genuinely expected is making a false declaration to obtain credit — it is fraud, and a statutory declaration is sworn under legislation with criminal penalties attached. Lenders and mortgage insurers do investigate, and the consequence can be the loan being called in.

What makes such a declaration false:

• Any expectation, written or verbal, that the money will be repaid
• A side agreement, IOU or note between you and your parents
• The parents holding a caveat or expecting a share of the property
• Repayments scheduled to start after settlement

If the money genuinely is a loan, say so. Disclose it, document it properly, and accept that it reduces your borrowing capacity. Many buyers find a guarantor home loan or a properly structured family loan is a cleaner path than dressing a loan up as a gift. Before you set a savings target, work through how much deposit you actually need.

Should the household contribution be reduced while saving for a house?

Often yes, and deliberately so. Many parents charge a below-cost figure precisely because the child is moving back home to save for a house. Just make the trade explicit: the discount is conditional on a fixed amount going into a deposit account each payday, verified by showing the balance at each review.

What if siblings feel the arrangement is unfair?

Raise it before it festers. Parents supporting one adult child with discounted housing while others receive nothing is a common source of estate disputes. Some families record the value of the benefit and adjust the will accordingly; others simply state openly that support is given as needed. Silence is what causes the damage.

Does living at home affect my parents’ Age Pension?

Your board payments are not usually treated as income to them under a genuine domestic arrangement, but a large gift they later make to you can affect their payment. Gifts above $10,000 in a financial year, or $30,000 over five years, are assessed as a deprived asset for five years and continue to count against the assets test.

Do we need a written agreement if it’s just family?

For board, a shared note or email is usually enough. For anything that must be repaid, a written loan agreement is essential. Without documentation, a family loan can be recharacterised as a gift in a dispute, and lenders will not accept undocumented family money as a legitimate deposit source at all.

Where to from here?

Moving home works brilliantly when the numbers are named and the boundaries are written down. Have the conversation, agree a contribution, set an exit date, and above all be honest about whether any money changing hands is a gift or a loan — because the day you apply for a mortgage, that answer has to be true.

If your parents are lending rather than gifting, do it properly: create a clear written family loan agreement in minutes with Chipkie so everyone knows the terms, the repayments and where they stand.
