One Doc Home Loans for Dentists — How Practice Revenue Counts When Tax Returns Don't
Most dentists think their low taxable income disqualifies them from a competitive home loan. It doesn't. A one doc home loan uses your BAS turnover or an accountant's income declaration to verify what your practice actually earns — not what your tax return shows after legitimate deductions.
Quick Answer
A one doc home loan lets dentists qualify using practice revenue verified through BAS statements or an accountant's letter — bypassing the tax return shortfall that blocks most standard applications for self-employed dental professionals.
Why Dentists Hit a Wall With Standard Home Loan Applications
The tax return problem for dentists is structural, not financial. A practice owner earning $400,000 in gross revenue might show $120,000 in taxable income after equipment depreciation, associate wages, lab fees, consumables and practice rent. That's smart tax planning — but a standard home loan lender sees a $120,000 income and sizes your borrowing capacity accordingly. The result: a dentist with strong cashflow gets approved for far less than they can comfortably service.
This gap between real revenue and taxable income is especially wide for dentists who have recently purchased or fitted out a practice. Depreciation on chairs, imaging equipment, sterilisers and fitout costs can suppress taxable income for years — exactly when you're most likely to be buying a home. The medical fitout finance you used to build the practice is now working against your home loan application under standard assessment.
A one doc home loan solves this by assessing income differently. Instead of relying on your tax return's bottom line, the lender uses one of two verification methods: your BAS turnover (annualised from the most recent four quarters) or a signed letter from your accountant declaring your income. Either method captures the practice's actual earning capacity rather than the tax-minimised figure. This is why alt doc and one doc products exist — they're designed for exactly this profile.
What Lenders Accept as Income Proof From a Dental Practice
One doc lenders typically accept one of two income verification paths for dentists. The path your broker recommends depends on your practice structure (sole trader, partnership, company or trust) and how clean your BAS history is.
Stronger Fit
- BAS turnover consistent across 4+ quarters
- Practice ABN registered 2+ years
- GST-registered with quarterly lodgements up to date
- No ATO debt or payment plan on record
- Accountant willing to sign income declaration
Gets Tricky
- BAS lodged late or missing quarters
- ABN less than 12 months old
- Revenue split across multiple entities without clear trail
- ATO debt above lender thresholds
- Accountant unwilling to declare income or provide letter
Path 1 — BAS verification: The lender annualises your GST turnover from the last four BAS lodgements. Most one doc lenders apply a percentage of that figure (typically 40–50% for professional services) as your assessed income. A dental practice with $800,000 annual GST turnover might be assessed at $320,000–$400,000 income — significantly more than a tax return showing $150,000.
Path 2 — Accountant's letter: Your accountant signs a declaration stating your gross and net income for the current or most recent financial year. This works well when your BAS quarters are lumpy (common in dental practices with seasonal demand) but your accountant can attest to a stable annualised figure. ASIC's MoneySmart guidance on self-employed lending obligations confirms that lenders can use accountant declarations as part of their responsible lending assessment, provided the declaration meets the lender's format requirements.
The what lenders see in a one doc application guide covers the full assessment matrix — including how debt-to-income ratios work under one doc rules versus standard full doc.
How the Application Process Works for Dentists
The one doc process for a dentist follows a specific sequence. Getting the order right avoids unnecessary credit enquiries and ensures the lender receives a complete file on first submission. Here's the typical broker-managed process from initial assessment to unconditional approval.
Eligibility pre-check
Your broker reviews your ABN age, BAS history, existing debts and target property value to identify which one doc lenders fit your profile. No credit pull at this stage.
Income document selection
Based on your practice structure, your broker determines whether BAS verification or an accountant's letter produces the stronger assessed income. For most dental practice owners, the accountant's letter is preferred when the practice runs through a company or trust.
Lender matching
Not all one doc lenders treat dental income the same way. Some apply a 40% revenue-to-income conversion; others allow 50% or use a specific formula for professional services. Your broker matches you to the lender whose assessment method maximises your borrowing capacity.
Submission and assessment
The full application goes in with your chosen income document, ID, bank statements, and the property details. One doc applications typically take 5–10 business days for conditional approval — faster than most standard full doc applications because the income verification is simpler.
If you're not sure which income path suits your practice, check your eligibility — it takes two minutes, no credit check required. See the full preparation guide at what to prepare before your first one doc application for the complete document list.
LVR Limits, Rate Premiums and What Dentists Should Expect
One doc home loans carry different terms to standard full doc products. The trade-off for simpler income verification is a lower maximum loan-to-value ratio and a modest rate premium. For dentists, the maths usually works out favourably because the assessed income is so much higher than tax return income — the better borrowing capacity more than compensates for the rate difference.
LVR: Most one doc lenders cap at 80% LVR, meaning you need a 20% deposit or equivalent equity in an existing property. Some specialist lenders extend to 85% for medical professionals with strong BAS history and no ATO debt — but 80% is the standard ceiling. Compare this to standard full doc, where 95% LVR is available — the 15% deposit gap is the cost of not having compliant tax returns.
Rate premium: One doc rates typically sit 0.5–1.0% above comparable full doc rates. On a $750,000 loan, that's roughly $3,750–$7,500 per year in additional interest. However, if a standard lender would only approve you for $500,000 based on your tax return, the one doc product gets you into the property you actually want — and you can refinance to a full doc product once your tax returns catch up to your real income.
For dentists carrying existing chattel mortgage debt on equipment, that monthly commitment reduces your loan servicing capacity. Your broker should model the interaction between your equipment finance commitments and your home loan borrowing power — sometimes restructuring the equipment finance to a longer term or lower balloon frees up enough servicing to increase your home loan approval. See the clinic fitout finance documents checklist for how equipment and home loan files intersect.
Dentists with strong practice revenue shouldn't be locked out of competitive home loans because their tax returns reflect legitimate business deductions. A one doc home loan assesses what your dental practice actually earns — through BAS turnover or an accountant's declaration — rather than the tax-minimised figure that standard lenders rely on. The trade-off is a 20% minimum deposit and a modest rate premium, but the borrowing capacity uplift typically makes the structure worthwhile for practice owners whose taxable income doesn't reflect their real earning power.
Key takeaway: If your dental practice revenue is strong but your tax return doesn't show it, a one doc home loan bridges the gap — and you can refinance to full doc once your returns catch up.Frequently Asked Questions
Yes. A one doc home loan assesses income using BAS turnover or an accountant's income declaration rather than your tax return's bottom line. This means a dentist with $600,000 in practice revenue but $130,000 in taxable income can be assessed on a figure much closer to their actual earning capacity. Most one doc lenders apply a percentage of gross revenue (typically 40–50% for professional services) as assessed income, which produces a significantly higher borrowing capacity than a tax-return-based assessment. The one doc home loan page explains the full product structure and eligibility criteria.
Most one doc lenders require a minimum 20% deposit (80% LVR). Some specialist lenders offer up to 85% LVR for medical professionals with strong BAS history, clean credit, and no outstanding ATO debt. Genuine savings held for three or more months, equity in an existing property, or a gift from a guarantor can all count toward the deposit requirement. If your deposit falls short, a self-employed home loan with a family guarantee structure may bridge the gap without requiring lenders mortgage insurance.
One doc home loan rates typically sit 0.5–1.0% above comparable full doc products. On a $750,000 loan, that represents roughly $3,750–$7,500 per year in additional interest. The rate premium reflects the lender's reduced documentation — they're accepting simpler income verification in exchange for a slightly higher margin. For many dentists, this trade-off is worthwhile because the one doc product approves them for a substantially larger loan than a standard product would. You can refinance to a full doc product once your tax returns reflect your true income. Read the why your accountant said no guide for common misconceptions about one doc pricing and risk.
Yes. Monthly repayments on chattel mortgages, equipment leases, and practice fitout finance all reduce your available servicing capacity for a home loan. A dental chair financed at $2,500 per month reduces your home loan borrowing power by approximately $40,000–$50,000 depending on the lender's servicing model. Your broker should model the interaction between existing equipment commitments and home loan capacity before submission. In some cases, restructuring equipment finance to a longer term or adjusting balloon payments frees enough servicing to meaningfully increase your home loan approval amount.
Yes. One doc home loans are available for both owner-occupied and investment purchases. Investment applications may attract a slightly higher rate (typically an additional 0.1–0.3% on top of the one doc premium) and some lenders apply a lower LVR cap of 75% for investment one doc loans. The income assessment process is identical — BAS verification or accountant's declaration — but the lender will also factor in projected rental income when calculating your total servicing position.
