Downsizing, CGT and Debt: A Practical Pre‑Retirement Playbook

You can use downsizing contributions, the main residence CGT exemption and deliberate debt reduction together to turn a property‑heavy balance sheet into reliable retirement income. The key is to map your loans, properties and tax position before you sell, then decide how much of the sale proceeds should clear debt, how much should go into super, and what (if anything) you keep outside super for flexibility.

In this guide we’ll step through how the downsizer rules work, how the main residence CGT exemption interacts with the new capital gains tax settings from 1 July 2027, and how to choose between deleveraging, keeping some gearing, or staying invested in property.

Coordinating home sale proceeds across super contributions and debt reduction creates a more stable retirement income base.

1. Big picture: what you’re really trying to optimise

For most pre‑retirees and downsizers, the real goal is not “pay the least tax” or “have zero debt”. It’s:

1. Sustainable, low‑stress income in retirement – enough after‑tax cashflow to live the way you want, without lying awake over interest rates.
2. Manageable risk – so one rate hike, vacancy or business shock doesn’t force a fire sale.
3. Flexibility – to help kids, fund aged care, or pivot if rules change again.

To get there, you need to coordinate three moving parts:

• Capital gains tax (CGT) – especially the main residence exemption and new 2027 rules.
• Superannuation contributions – including downsizer contributions that bypass normal caps.
• Debt levels and loan structures – home, investment and business lending.

If you haven’t already, it’s worth reading the broader property‑heavy pre‑retirement strategy piece: Smart moves for pre‑retiree property investors under new tax rules. This article zooms in on one specific play: selling or downsizing your home and redeploying the proceeds.

2. Key concepts in plain English

2.1 Downsizer contributions – what they really are

A downsizer contribution is a special one‑off contribution you can make to super using the proceeds from selling your home. Key points (at time of writing):

• Up to $300,000 per person ($600,000 per couple) regardless of standard contribution caps.
• You must be at least 55 at the time of contribution (check current age settings when you act).
• The property must generally have been your main residence (or at least eligible for the exemption) for part of the ownership period.
• You must contribute within 90 days of settlement (some extensions possible from the ATO).

The contribution itself isn’t tax‑deductible, but once inside super, earnings are taxed at up to 15% in accumulation, and often 0% in pension phase, which is where the long‑term tax benefit lives.

2.2 Main residence CGT exemption – why your home is special

Generally, selling your main residence in Australia triggers no CGT if:

• It’s been your main residence for the entire ownership period, and
• The land is 2 hectares or less, and
• You haven’t used it mainly to produce assessable income.

If it’s been partly rented out or used as a business base, you can get a partial exemption.

With the 2026–27 reforms, from 1 July 2027 most individuals and trusts lose the 50% CGT discount and instead get indexation and minimum tax settings. But the main residence exemption remains incredibly valuable – often the last big tax‑free card you can play. (See Capital gains tax, your home and geared property under new rules for a deeper dive.)

2.3 Debt – why structure matters as much as size

Not all debt is equal:

• Home loan (non‑deductible) – interest is usually not tax‑deductible because loan purpose is personal housing, regardless of which entity is on title. (This follows from the rule that interest deductibility follows purpose, not security.)
• Investment property loan (usually deductible) – interest is often deductible where the borrowing is used to produce assessable income.
• Business/working capital loans (usually deductible) – interest is generally deductible for business purposes.

From a purely tax perspective, you want less non‑deductible debt and, if you’re comfortable with risk, you can sometimes justify keeping some deductible investment or business debt.

But tax is only one lens. You also have to weigh:

• Interest rate differentials (home vs investment vs business loans).
• Cashflow volatility (e.g. rent, business profit, vacancy risk).
• Your realistic retirement spending and risk tolerance.

3. How these three levers interact

3.1 The intuitive but incomplete plan

A common first thought is:

“We’ll sell the big house, clear all debt, and put whatever’s left into super.”

Sometimes that’s exactly right. But it can be sub‑optimal if:

• You wipe all your cheap‑ish, deductible investment debt instead of non‑deductible home or business debt.
• You miss the chance to use the downsizer contribution because of timing or age.
• You accidentally boost assets in the wrong place for Age Pension tests.

3.2 A better approach: sequence and structure

A more robust plan usually runs in this order:

1. Map everything: properties, loans, super balances, ages, entity structures, and whether each property is main residence, investment or business.
2. Clarify your 10‑year picture: where you’ll live, whether you want to keep any investment property, and when you plan to partially or fully retire.
3. Decide what to sell, and when: factoring in CGT, new 2027 rules, and property market realities.
4. Prioritise which debts to clear: non‑deductible first, subject to rates and risk.
5. Plan contributions to super: downsizer vs non‑concessional and timing of pension phase.
6. Rebuild your loan structure: keep remaining debt cleanly split between home, investment and business purposes.

You might find it helpful to cross‑reference long‑term planning guides like Designing a 10‑Year Property and Mortgage Roadmap in Sydney’s East or Turn Your Mascot Home Loan into a 10‑Year Property Strategy for how to think about the planning horizon.

4. Worked example: couple downsizing in their early 60s

4.1 Their starting position

• Ages 62 and 60, both still working part‑time.
• Current home in Sydney’s east, worth $3.0m, no significant private business use.
• Outstanding home loan $400,000 (P&I, rate 6.0%).
• Investment unit worth $1.2m, investment loan $700,000 (interest‑only, 6.3%).
• Combined super balances $900,000.
• They want to work 3–5 more years, then semi‑retire.

They are considering selling the home, buying a smaller townhouse, and possibly selling the unit later.

4.2 Step 1 – CGT on main residence

The home has been their main residence the whole time. Under current law:

• Sale price: $3.0m
• Cost base: say $1.2m (purchase + eligible costs)
• Capital gain: $1.8m – but fully covered by the main residence exemption.
• No CGT payable on the home sale.

4.3 Step 2 – Net cash after downsizing purchase

Assume they:

• Sell home for $3.0m.
• Pay agent, legal and selling costs of $80,000.
• Clear the $400,000 home loan.
• Purchase a townhouse for $1.6m.
• Pay purchase costs (stamp duty, legal etc.) of $80,000.

Summary:

• Net sale proceeds: $3.0m – $80k = $2.92m.
• After repaying home loan: $2.92m – $400k = $2.52m.
• After buying townhouse and purchase costs: $2.52m – $1.68m = $0.84m leftover.

They now have:

• No home loan (if they choose not to re‑borrow).
• Existing investment loan $700,000 on the unit.
• $840,000 sitting in cash/offset somewhere, ready to deploy.

4.4 Step 3 – Downsizer contributions vs clearing investment debt

They could:

1. Use downsizer contributions:

   • Each spouse contributes $300,000 to super as downsizer contributions.
   • That’s $600,000 into super, outside normal caps.
   • Remaining cash: $840,000 – $600,000 = $240,000.

2. Clear some or all investment debt instead:

   • Pay off the $700,000 investment loan.
   • Keep the unit unencumbered, but forgo the downsizer opportunity if they miss the timing or caps.

In practice, they might blend these:

• Put $600,000 into super via downsizer contributions.
• Use $240,000 to partially reduce the investment loan.

4.5 Impact on cashflow (illustrative)

Assume the investment loan is 6.3% interest‑only.

Reducing the loan by $240,000 saves about $15,120 per year in interest. While interest is deductible, in their 34.5% marginal tax bracket (incl. Medicare), the after‑tax saving is still material.

If they invest $600,000 inside super earning, say, 6% total return with 15% tax on earnings in accumulation:

• Gross earnings: 6% × $600,000 = $36,000.
• Tax at 15%: $5,400.
• Net earnings: $30,600 per year.

If they instead kept the $600,000 in a personal investment at 6% with 34.5% tax on earnings:

• Gross: $36,000.
• Tax at 34.5%: $12,420.
• Net: $23,580.

So super delivers about $7,020 per year more after tax on the same investment assumption.

This is why the downsizer rules can be powerful when coordinated with debt decisions.

5. Debt strategy: how much to clear, and in what order

5.1 Prioritising non‑deductible debt

Because interest on your main residence loan is generally not deductible, each dollar reducing that debt gives you an after‑tax return equal to the interest rate. If your home loan is 6.0%, paying it down is like a risk‑free 6.0% after‑tax return.

By contrast, investment or business loan interest is often deductible, so the after‑tax cost is lower.

Rule of thumb:

1. Clear/contain non‑deductible home and consumer debt first.
2. Then weigh up clearing investment or business debt versus investing more inside super.

This aligns with debt recycling principles discussed in more detail in /insights/debt-recycling-tax-effective-loan-structuring-australia.

5.2 Comparing pay‑down vs invest in super

Here’s a simple comparison, assuming you’re 60, comfortable with super rules, and have a 6% home loan.

If you are highly risk‑averse or already have plenty in growth assets, paying down debt can be the cleaner path.

If you still have a reasonable investment timeframe and can tolerate risk, using downsizer contributions to boost super while keeping some manageable, well‑structured deductible debt can make sense.

5.3 Don’t forget lending rules and buffers

Lenders now apply at least a 3% APRA serviceability buffer when testing new loans or refinances. That means if your interest rate is 6%, your borrowing is assessed at 9% or more.

Selling and downsizing can improve your serviceability if you:

• Cut non‑deductible debt.
• Lock in lower, predictable repayments.
• Simplify structures (e.g. uncross loans, separate home vs investment splits).

But if you plan to keep some gearing into retirement, your structure matters even more. This is where working with a broker who focuses on risk, not just approvals, is crucial. See How a Local Broker Uses Risk Insight, Not Just Loan Approval for what to expect from that conversation.

6. CGT timing under the 2027 reforms

6.1 Why dates matter now

The Treasury Laws Amendment (Tax Reform No. 1) Bill 2026 reshapes CGT for individuals and many trusts from 1 July 2027:

• The familiar 50% CGT discount is replaced by CPI indexation and a minimum 30% tax on many gains.
• Some pre‑CGT assets are brought into the net prospectively.
• There are complex transitional and deemed disposal rules.

Your main residence exemption largely survives, but investment properties and some business assets become more heavily taxed on sale.

This means that for property‑heavy pre‑retirees, the sequence of sales matters:

• Do you sell the home first (no CGT, unlock downsizer) and keep investments geared?
• Or realise investment gains before or after 1 July 2027, depending on which regime is more favourable?

The broader strategy around timing multiple sales is covered in /insights/pre-retiree-downsizer-smsf-property-heavy-strategy. Here we focus on how it interacts with downsizing.

6.2 Example: investment property sale pre‑ vs post‑2027

Assume:

• Investment unit cost base: $700,000.
• Current value: $1.2m.
• Capital gain: $500,000.

Before 1 July 2027 (current rules, simplified):

• 50% discount for individuals after 12 months.
• Taxable gain: $250,000.
• At 34.5% marginal tax rate: tax ≈ $86,250.

After 1 July 2027 (illustrative):

• Cost base indexed with CPI, say 10% uplift (illustrative only).
• Indexed cost base: $770,000.
• Nominal gain: $430,000.
• If a 30% minimum tax applies: tax ≈ $129,000.

That’s a difference of more than $40,000 in tax on the same economic gain, depending on timing and how final rules land.

You don’t decide this in a vacuum. You overlay:

• What you’re doing with the home sale and downsizer contributions.
• Whether paying that tax allows you to dramatically improve lifestyle or risk.
• How much debt you’ll still carry afterwards.

7. Quick readiness check: is a downsizing‑plus‑super strategy right for you?

Use these questions as a 10‑minute filter before you dive into valuations and spreadsheets.

7.1 Your life stage and goals

• Are you 55 or older, or close to that, so downsizer contributions are on the table soon?
• Do you realistically plan to stay in your next home for 10+ years?
• Is your main motivation lifestyle, cashflow relief, or tax efficiency – and in what order?

7.2 Your property and debt profile

• Is your current home a significant share of your net worth (e.g. more than 50–60%)?
• Do you have non‑deductible home debt that feels heavy or risky into retirement?
• Do you own investment or business property with sizeable but manageable debt?

7.3 Your super and income mix

• Is your super balance lower than you’d like relative to your age and desired retirement income?
• Are you or your partner still earning enough to make good use of concessional contributions in parallel?
• Are you likely to seek the Age Pension at some point, or self‑fund fully?

If you’re answering “yes” to most of these, a coordinated downsizer/CGT/debt plan is worth serious attention this year, not “sometime later”.

A simple readiness check helps you decide whether a downsizing‑plus‑super strategy is right for you this year.

8. Structuring loans around your downsizing move

8.1 Keep loan purpose silos clean

One of the most important lending rules is that loan purpose, not the securing property, determines interest deductibility. That makes it crucial to keep separate splits for:

• Home (non‑deductible)
• Investment
• Business

When you sell your main residence, buy a new one and perhaps keep or rejig investments, take the chance to tidy up your loan structure so future changes (e.g. renting out your new home) are easy to track.

This is the same logic used when renovating with future rental use in mind, as outlined in /insights/financing-rose-bay-renovations-extensions-rebuilds.

8.2 Example: separating new home and investment loans

Suppose after downsizing you:

• Need a $300,000 top‑up loan to complete the townhouse purchase.
• Still have a $700,000 investment loan on the unit.

Work with your broker to:

• Create Split A – Home loan: $300,000.
• Create Split B – Investment loan: $700,000.

Keep them separate in:

• Loan contracts.
• Internet banking.
• Offset accounts (ideally a separate offset linked to the home split).

If, in the future, you sold the unit and used proceeds to invest again, you’d likely create new investment splits rather than muddling the home loan.

8.3 Using an offset instead of redraw

When you’re approaching retirement, it’s often safer to keep surplus cash in an offset account rather than fully paying down a home loan and then re‑borrowing later.

Why:

• You maintain flexibility to access funds without needing fresh loan approval.
• If you later rent the property out, you can retain a larger deductible loan balance while still having effectively lowered interest costs along the way.

But this has to be done with purpose‑based borrowing in mind. Mixing home and investment uses through redraw can create a tax mess. The debt recycling article at /insights/debt-recycling-tax-effective-loan-structuring-australia explains this in depth.

9. Age Pension and cashflow: don’t accidentally trip the assets test

9.1 Your home vs assessable assets

Under current rules, your principal home is exempt from the Age Pension assets test (up to a generous land size limit). But:

• Cash, investments and most super (once you’re Age Pension age and have started drawing) are counted.

So if you:

• Sell a $3.0m home and buy a $1.4m unit, and
• Bank the remaining $1.6m into super and other investments,

you may improve lifestyle and diversification but increase your assessable assets for the Pension.

The right move depends on:

• Whether you’d be eligible for a part‑Pension anyway.
• How much you value a secure income stream vs a government payment.

9.2 Example: impact on a couple close to Age Pension age

Assume a couple:

• Age 67 and 65.
• Sell a $3.0m home, buy a $1.5m townhouse, free of debt.
• Invest $1.3m leftover in super and other financial assets.

Under current rules:

• As homeowners, the assets test threshold for a couple is significantly lower than $1.3m (check current figures when you act).
• That means their Pension entitlement may be reduced or nil, even though their new financial investments can provide income.

This doesn’t mean downsizing is wrong. It means:

• You should project Pension outcomes and private income side by side.
• You may consider staging moves over several years, or adjusting how much you keep in different structures.

10. Coordinating tax, lending and legal advice

Downsizing, CGT and debt levels sit right at the intersection of:

• Tax law (ATO, Budget 2026–27 reforms, super rules).
• Lending policy (APRA buffers, bank serviceability, security and LVR limits).
• Estate planning and family law (future inheritances, guarantees, aged care).

We’ve seen repeatedly that coordinated advice upfront is cheaper than fixes later. This mirrors the lesson from /insights/coordinating-smsf-personal-company-property-moves-new-rules: joint sessions across adviser disciplines significantly reduce contradictory advice.

A joined‑up session should cover:

• A single one‑page map of all properties, loans, entities and super.
• How the new CGT and negative gearing rules affect your portfolio.
• How much debt you can comfortably carry with realistic retirement income.
• Which property sales should happen before vs after 1 July 2027.
• Whether to involve an SMSF for any new property exposure.

For complex or higher‑value portfolios, also consider how inter‑generational plans—such as helping children with property—fit into your downsizing moves, as discussed in /insights/structuring-family-assistance-children-expensive-markets.

11. Choosing the right adviser mix and broker style

If you’re reading this, you probably know you don’t just need a loan “approved”. You need a plan.

When picking a mortgage and finance adviser for this stage of life, weigh up:

• Online / digital‑only – efficient for simple transactions, less suited to multi‑property, SMSF or estate‑sensitive work.
• Phone‑based national brokers – good for busy professionals, but may not know your local market intimately.
• Local, strategy‑led broker with tax literacy – particularly useful when you’re coordinating CGT, downsizer contributions and complex debt.

For a more detailed rundown of pros and cons, see /insights/online-phone-vs-local-mortgage-brokers-australia.

Joint strategy sessions across tax, lending and super can turn a downsizing idea into a concrete, low‑risk plan.

12. One‑week action plan you can realistically do

Day 1–2: Map your current position

• List each property: use, value, loan, ownership entity, and whether main residence, investment or business.
• Collect loan statements and super balances.
• Sketch a simple 10‑year timeline: when you’d like to move, semi‑retire, fully retire.

Day 3–4: Explore scenarios at a high level

• Roughly estimate sale proceeds from your current home less selling costs and debt.
• Shortlist two or three downsizing options (locations, price ranges).
• For each option, estimate leftover cash and how much could go into super vs debt reduction.

Day 5: Sense‑check CGT and Pension implications

• Note which assets are fully or partially covered by the main residence exemption.
• Flag any investment properties with large unrealised gains.
• Do a high‑level Age Pension check using Services Australia calculators (you’re just getting a ballpark).

Day 6: Book coordinated advice

Aim for a joined‑up conversation that includes:

• A tax adviser/CPA who understands the 2027 CGT and negative gearing reforms.
• A mortgage/finance broker who can model borrowing capacity and cashflow under different debt levels.
• Potentially your super/SMSF adviser, if you’re considering property inside super or large downsizer contributions.

Have them work off the same one‑page map you prepared.

Day 7: Decide your next concrete step

Based on that meeting, choose one tangible action:

• Get a preliminary valuation of your current home.
• Start refinancing or restructuring loans to separate home and investment splits.
• Set a target date to sell, relative to 1 July 2027, and build a reverse timeline.

13. Comparison tables: common downsizer strategies side‑by‑side

13.1 Strategy typologies

13.2 Where the sale proceeds go

14. Common mistakes and how to avoid them

14.1 Selling the wrong property first

It’s easy to default to “sell the investment first, keep the home”. Sometimes that’s right. But if the investment has a large embedded gain and the home does not, the CGT difference under post‑2027 rules can be stark.

Avoid this by modelling both:

• Sell home, keep investment(s) with manageable gearing.
• Keep home, sell investment(s) now vs after 1 July 2027.

14.2 Missing the downsizer window

You can only make downsizer contributions from one home sale, and within prescribed timeframes.

Pitfalls include:

• Settling just before a birthday that makes downsizer eligibility possible, but not waiting.
• Forgetting to lodge the downsizer contribution form with your super fund.

You don’t have to use the full $300,000 each; but you rarely get a better chance to boost tax‑favoured retirement capital.

14.3 Messy loan structures

Combining home and investment purposes in a single redraw‑heavy facility before, during or after downsizing creates:

• Deductibility headaches for your accountant.
• Risk that ATO denies deductions if purpose can’t be clearly traced.

Tidy splits and clear documentation are the fix.

14.4 Underestimating rate and cashflow risk

Recent Roy Morgan research shows around 28.2% of mortgage holders were at risk of stress in early 2026, with more at risk if rates rise. Entering retirement with high gearing and thin buffers is asking to join that cohort.

Aim to:

• Stress‑test your new structure at least 3% above current rates.
• Maintain 3–6 months of all housing repayments (home + investment) in cash or offset.

15. Key takeaways and next steps

Key takeaways

• Your main residence is still a powerful tax lever. Used well, the CGT exemption lets you unlock large tax‑free capital and redeploy it towards debt reduction and super.
• Downsizer contributions are a one‑off opportunity. Up to $300,000 per person can move from after‑tax savings into tax‑favoured super, but timing and eligibility rules are strict.
• Prioritise non‑deductible debt first. Clearing home loans usually gives the highest, risk‑free after‑tax return, but you may keep sensible investment gearing if your buffers and risk tolerance allow it.
• The 2027 CGT reforms make sequencing crucial. Deciding which properties to sell before vs after 1 July 2027 can shift tax outcomes by tens of thousands of dollars.
• Loan structure and documentation matter. Keep home, investment and business borrowing in clean splits so interest deductibility and future moves aren’t compromised.
• Age Pension tests can move against you when you downsize. Replacing home equity with financial assets can reduce future Pension entitlements even while improving lifestyle.
• Coordinated advice beats patchwork decisions. Tax, lending and super strategies should be designed in one conversation using a shared map of your position.

What to do now

If you’re within 10 years of retirement and considering a property sale or downsize, this is the time to get a coordinated view of your tax, loans and super – not after the contract is signed.
