Self-Employed Home Loan Refinance: When to Switch (2026)
Refinancing a self-employed home loan makes sense when the rate gap, equity position, or structure change justifies the break cost. This guide maps the specific timing triggers so you switch when the numbers work, not when a rate headline tells you to.
Quick Answer
Refinancing a self-employed home loan makes sense when a genuine structural trigger fires — not just because rates moved. The triggers that justify the switching cost include fixed-rate expiry, an income documentation upgrade, a material equity shift, or a lender-policy change that opens a better product class.
Six Triggers That Justify a Self-Employed Refinance
A refinance only works when the long-term saving outweighs the cost of switching. For self-employed borrowers on alt doc or one doc home loans, the switching cost is higher than a PAYG refinance because the documentation process is heavier. These six triggers are the situations where the maths consistently works.
Fixed-rate expiry
Your fixed rate rolls to a variable rate that is materially higher. This is the cleanest trigger — no break cost, no penalty, and you can shop the entire market. With the RBA indicatively at 4.10% as of March 2026 and markets pricing further tightening, the variable rate you roll onto may be significantly above your fixed rate. Refinancing before the rollover date locks in your options.
Income documentation upgrade
You started on a low doc or alt doc product because your tax returns weren't ready. Now you have two years of returns filed and your accountant can produce financial statements — which qualifies you for full doc rates. The rate gap between alt doc and full doc can be meaningful over the life of the loan.
Equity threshold crossed
Your property value has grown (or you've paid down the loan) enough to push your LVR below a pricing break — typically below 80%, 70%, or 60%. Each LVR band unlocks lower rates and, at 80% or below, removes lenders mortgage insurance from the equation entirely. A desktop valuation from a broker costs nothing and confirms whether you've crossed the line.
Structure change
You moved from sole trader to a company or trust, or you added a partner. Your existing lender may not recognise the new structure as easily as a lender who assesses you fresh. A refinance lets you present the current business structure from the start rather than retrofitting an old application. See multiple revenue streams for how lenders handle multi-entity income.
Lender-policy shift
Non-bank lenders regularly update their credit policies. A lender that rejected your profile 12 months ago may now accept it — or a lender you're currently with may have tightened terms on existing customers while a competitor opened up. Your broker monitors these policy shifts across the panel. This is the trigger most borrowers miss because it's invisible without broker-level access.
Debt consolidation opportunity
You're carrying separate term loans, equipment facilities, or ATO debt alongside your home loan. Consolidating into a single facility at a lower blended rate can reduce total monthly outgoings — but only if the combined servicing improves. A broker models the before-and-after to confirm the numbers.
When a Self-Employed Refinance Stalls
Not every refinance that looks good on paper actually settles. Self-employed borrowers face friction that PAYG borrowers don't — and knowing where the stall points sit prevents you from burning time and application fees on a switch that won't land.
Refinance works
- Two or more years of consistent ABN trading history
- Clean bank statements showing stable deposits over 6 months
- LVR typically below 80% on current valuation (not purchase price)
- No ATO debt or a documented ATO payment plan in good standing
- Rate gap of indicatively 0.50%+ between current and target product
Refinance stalls
- ABN less than 12 months old — most non-bank lenders require 12+ months
- Recent credit enquiries from shopping around without a broker
- Taxable income heavily minimised with no self-declaration pathway
- Break cost on a fixed rate exceeds 12 months of rate saving
- Existing lender holds security over multiple properties (cross-collateralisation)
If your situation sits in the "stalls" column, that doesn't mean a refinance is off the table permanently. It means the timing isn't right yet. A broker can map the path from where you are to where you need to be — sometimes that's 90 days of cleaner bank statements, sometimes it's waiting for a fixed-rate expiry. See the 90-day fix path for the structured recovery approach.
Break Costs: How to Know If the Switch Pays for Itself
Break costs are the fee a lender charges for exiting a fixed-rate loan before the term ends. They vary by lender policy and the difference between your fixed rate and the current wholesale rate — so they can be trivial or they can be substantial. The only way to know is to request a formal break cost quote from your current lender. This is free and doesn't commit you to anything.
The calculation is straightforward. Compare the total break cost against the total rate saving over the remaining loan term. If refinancing from one product to another saves you an indicative $3,000 per year in interest and your break cost is $5,000, the refinance pays for itself within approximately two years. If the break cost is $15,000 and the saving is the same $3,000 per year, you're looking at five years to break even — which may not justify the switch.
Your broker can request the break cost quote and model the payback period before you commit. Check your eligibility to start the conversation — there's no credit check and no obligation at this stage.
Switching to a One Doc Home Loan: What Changes
A one doc home loan uses an accountant's declaration of income instead of tax returns as the primary verification. For self-employed borrowers whose taxable income sits well below their actual earning capacity — because the accountant has legitimately minimised tax — this is the product that matches what you actually earn to what you can borrow.
The refinance from a full doc or alt doc product to a one doc product is a structural change, not just a rate change. The lender assesses your directors declaration or accountant's letter, your BAS to verify GST turnover, and your bank statements to confirm deposit patterns. The assessment is faster than full doc — typically days rather than weeks — but the rate is indicatively higher because the lender carries more verification risk.
When the switch makes sense: your taxable income is low enough that no full doc lender will approve the borrowing amount you need, but your actual business revenue and cash position support the repayments comfortably. This is the scenario where one doc unlocks borrowing capacity that doesn't exist in the full doc world.
If you've been declined on a full doc refinance because your debt-to-income ratio doesn't work against your tax return, the one doc pathway assesses your income differently. See 3 myths about one doc home loans for the common misconceptions, and alt doc vs one doc for a side-by-side comparison of both pathways.
What the Self-Employed Refinance Process Looks Like
The mechanics of a self-employed refinance follow the same broad path as any refinance, but the documentation requirements and timelines differ. Here's the sequence from first conversation to settlement.
Eligibility check and scenario modelling
Your broker reviews your current loan, property value, income structure, and the trigger driving the refinance. No credit check at this stage. Time: one conversation.
Break cost quote from current lender
If you're on a fixed rate, request the formal break cost figure. This is free and non-binding. Time: 1–3 business days.
Document preparation
For a one doc refinance: accountant's declaration, 6 months of bank statements, BAS, and identification. For full doc: add two years of tax returns and financial statements. Time: depends on your accountant's turnaround.
Lender submission and assessment
Your broker submits to the best-fit lender from across the panel. Non-bank lenders typically assess one doc applications faster than major banks process full doc — indicatively 3–7 business days to conditional approval.
Valuation and unconditional approval
The new lender orders a property valuation. Desktop valuations are common for refinances under 80% LVR. Full valuations take longer and apply where the LVR is higher or the property is non-standard. Time: 2–5 business days after conditional approval.
Discharge and settlement
Your solicitor or conveyancer coordinates the discharge of your old loan and settlement of the new one. The outgoing lender releases the mortgage, the incoming lender registers theirs. Time: indicatively 2–4 weeks from unconditional approval.
Total timeline from first conversation to settlement is typically 4–8 weeks for a straightforward refinance. Complex scenarios — cross-collateralised securities, multiple entities, or ATO debt — take longer. Your broker manages the entire process. Start a conversation to map the timeline for your situation.
Refinancing a self-employed home loan is worth doing when a genuine trigger fires: your fixed rate expires, your income documentation improves, your equity crosses a pricing threshold, or your business structure changes. It's not worth doing for a marginal rate cut that doesn't outweigh the switching cost. The RBA is indicatively at 4.10% as of March 2026 with markets pricing further movement — which means the timing question is real and the answer depends entirely on your specific numbers.
Key takeaway: Refinance when a structural trigger fires and the break cost maths works — not because a headline rate looks better.Frequently Asked Questions
The best time to refinance a self-employed home loan is when a structural trigger fires: your fixed rate expires, your LVR drops below a pricing threshold (typically 80%), your income documentation improves enough to qualify for a better product class, or your business structure changes in a way that a new lender assesses more favourably. Refinancing purely for a marginal rate cut rarely justifies the switching cost for self-employed borrowers because the documentation burden is heavier than a PAYG refinance. A broker can model the break-even calculation for your specific scenario — see the one doc home loan page for the product pathway most self-employed refinances land on.
Refinancing costs typically include a discharge fee from the outgoing lender (varies by lender), government registration fees for the new mortgage (varies by state), and any break costs if exiting a fixed rate early. Some incoming lenders waive application and valuation fees as part of their refinance offer. The total cost varies significantly — from a few hundred dollars for a variable-rate discharge to several thousand for a mid-term fixed-rate exit. The key test is whether the total switching cost is recouped within a reasonable period through the lower rate or better terms. Your broker models this payback period before you commit. See the asset refinance glossary entry for the general mechanics and cash-out refinance for situations where you're also releasing equity.
Yes — this is exactly the scenario that one doc home loans and alt doc home loans are designed for. Instead of assessing your borrowing capacity against your tax return, a one doc lender uses an accountant's declaration of your actual income alongside your BAS and bank statements. If your business earns significantly more than your taxable income shows — because your accountant has legitimately applied deductions, depreciation, and prepayments — the one doc pathway assesses what you actually earn, not what the ATO sees. The rate is indicatively higher than full doc, but the borrowing capacity is materially larger. See refinancing to a one doc home loan for the step-by-step pathway.
Waiting for rates to drop is a gamble, not a strategy. The RBA is indicatively at 4.10% as of March 2026 with CPI running at roughly 3.70% — above the 2–3% target band — and markets are pricing the possibility of further tightening rather than cuts. If your refinance trigger has already fired (fixed-rate expiry, equity threshold crossed, documentation upgrade available), acting now locks in the improvement. If you wait and rates rise further, both your current variable rate and your refinance target rate move up together. The exception: if you're on a fixed rate that expires within 3–6 months, waiting for expiry avoids break costs — that's a genuine timing play. For everything else, run the numbers with a broker against the ATO's general guidance on deductible loan costs and assess the decision based on your specific situation, not a forecast.
For a one doc refinance: an accountant's declaration of income, 6 months of business and personal bank statements, your most recent BAS, and standard identification. For a full doc refinance: two years of personal tax returns, two years of business financial statements, 6 months of bank statements, and an ATO Notice of Assessment. The one doc pathway requires fewer documents but the ones you provide need to be clean — consistent deposits, no unexplained withdrawals, and a GST turnover that supports the declared income. Your broker will send a tailored checklist once they've assessed your scenario. See the one doc home loans for doctors guide for an example of how the documentation works in practice.
