Untangling Business, Trust And Personal Debt Before You Apply

Banks now look at your whole group – personal, business and trust – when assessing a loan. Here’s how they actually treat each debt, and what to fix this week before you apply.

Key Takeaway

Australian lenders typically assess business, trust and personal debts on a consolidated basis, with most personally guaranteed facilities treated as personal liabilities for serviceability. This can materially reduce borrowing capacity, especially for directors with multiple entities and SMSFs. By mapping entity structures, clarifying guarantees, and cleaning up short‑term facilities 6–12 months before applying, borrowers can present a clearer income and debt story and preserve capacity for premium property purchases.

Untangling Business, Trust And Personal Debt Before You Apply

When your business, trust and personal borrowing collide, banks don’t pick and choose – they usually assess the whole group together and treat personally guaranteed debts as yours. If you’re a director, trustee or guarantor, business and trust loans can bite hard into home‑loan or investment‑loan capacity unless they’re structured and documented well.

Below is how the assessment actually works – and what you can fix this week.

Person connected to home, company, trust and SMSF loans in one diagram. Lenders increasingly assess your whole group – personal, business, trust and SMSF – as one picture.

1. How lenders really see your “group” debt

For complex borrowers, most mainstream lenders now:

  1. Map your structure – personal, companies, trusts, SMSF.
  2. Pull all ATO, credit file and bank information they can.
  3. Identify any facility with a personal guarantee and pull it into your personal picture.
  4. Apply at least a 3% serviceability buffer (APRA) to most variable and short‑term debts.

Key points:

  • Personally guaranteed business loans, overdrafts and equipment finance are typically treated as personal commitments in home‑loan assessments.
  • Loans to companies or trusts with personal guarantees are almost always counted in your serviceability calculations.
  • SMSF and trust properties that “wash their face” on paper can still drag capacity because of buffers on those loans and shade on rental income.

2. What actually gets counted in serviceability

Here’s how common facilities are usually treated.

Facility typeWhere it sitsHow banks often treat it
Director home loanPersonalFull repayments assessed with 3% buffer
Business overdraft with PGCompany, PG by youLimit or assessed repayment counted as your personal debt
Equipment finance with PGCompany, PG by youMonthly repayment counted personally
Trust investment loan with PGTrust, PG by youFull debt + shaded rental counted in your file
SMSF limited recourse loanSMSFSMSF loan + shaded rent can still reduce personal capacity
ATO payment plan (business or personal)Entity or youTreated like a term loan with required monthly repayments

PG = Personal Guarantee.

Income side – the other half of the collision

On the income side, lenders usually:

  • Prefer stable salary or director fees over lumpy dividends or trust distributions.
  • Average two years of business income, often shading down for volatility.
  • Look hard at how much cash actually leaves the business to you after tax.

If your group is geared across a company, trust and SMSF, each extra loan can mean extra buffers and shading, even where the structure looks tax‑efficient.

Frequently asked questions

Do banks look at my business debts when I apply for a home loan?▾
Yes. If you’ve given a personal guarantee on business debts such as overdrafts, equipment finance or term loans, most Australian lenders treat those as your personal commitments. They model the repayments with a serviceability buffer, which can significantly reduce how much they’ll lend you for a home or investment property.
How do trust loans affect my personal borrowing capacity?▾
Where you’re a director or trustee and have provided personal guarantees, lenders usually include trust loans in your personal serviceability assessment. They apply buffers to the trust debt and shade the rental income, so even a self-funding trust property can reduce your capacity for a new home or investment purchase.
What can I do this month to improve my position before applying?▾
Start by mapping all entities and debts, including limits and guarantees, then close unused facilities and tidy small personal debts. Work with a broker and your accountant to restructure short-term business debt off long 30-year home-loan terms, and to present a clear, stable income story for at least the last two years.
