Quick answer
When you move from sole trader to company, the company becomes a separate legal entity with its own ABN and bank account. For borrowing, that means the company is the borrower, directors usually sign personal guarantees, and some lenders may treat the new ABN as a fresh start. Keeping records from both structures and explaining the change helps lenders see the full trading history.
Key points
- A company is a separate legal entity; a sole trader is not.
- The company gets its own ABN and must have its own bank account.
- Directors need a director ID before the company is registered.
- Lenders usually ask directors to personally guarantee company loans.
- Keep sole-trader records so lenders can see your full history.
Plenty of businesses start life as a sole trader. It’s simple, cheap and quick. Then the business grows, an accountant mentions “maybe it’s time for a company”, and a new question pops up: what does this change do to my ability to borrow?
This guide explains it in plain English. It won’t tell you whether to restructure (that’s a conversation for your accountant). It will help you understand what lenders see before and after.
What’s the actual difference between a sole trader and a company?
business.gov.au puts it simply:
- A sole trader is legally responsible for all aspects of the business. You and the business are, legally, the same person.
- A company is a legal entity that’s separate from you. It can own things, sign contracts, owe money and borrow in its own name.
That separation is one of the main reasons people set up companies. But it changes how borrowing works in some important ways.
What changes when the company is the borrower?
| As a sole trader | As a company | |
|---|---|---|
| Who borrows | You, personally | The company |
| ABN | Your sole-trader ABN | The company’s own new ABN |
| Bank account | Separate account strongly encouraged | Separate account required |
| Who’s responsible for the debt | You, directly | The company, plus usually directors via personal guarantee |
| What lenders check | Your business and personal position together | The company’s trading, plus directors’ credit and position |
| Documents | Your ID, statements, BAS, returns | Company details plus directors’ ID and information |
Does your trading history start again?
On paper, a new company is new. It has its own ABN, and the ABN registration date is visible on ABN Lookup. Some lenders’ systems will see “ABN registered four months ago” and treat it like any new business.
But many lenders will look at the business as a whole if you help them. That means:
- explaining that the company took over an existing sole-trader business
- providing bank statements and BAS from both structures
- showing the same customers, the same work and the same owner carrying on
Illustrative example. Ravi ran a successful signage business as a sole trader for four years, then moved it into a company last July. When he applies for a loan in March, the company ABN is only eight months old. By supplying his sole-trader statements and returns alongside the company’s, and a one-line explanation of the restructure, he gives the lender a clear view of five years of continuous trading. (Illustrative only.)
Our lesson on how long you’ve traded explains why that history matters so much.
Why will you be asked for a personal guarantee?
This surprises many new directors. “I set up a company so my personal assets are separate, and now the lender wants me to guarantee the loan?”
Yes, usually. Because the company is a separate entity, a lender lending only to the company could only recover from the company’s own assets, which for a small company may be limited. A personal guarantee gives the lender a director to look to if the company can’t pay. For most small company loans, it’s what makes lending possible at all.
Read it carefully and get independent advice. Our lesson on personal guarantees explains exactly what to look for.
What admin comes with a company?
A few things first-time company owners should know, because lenders may ask about them:
- Director ID. ASIC’s registration steps say directors must apply for a director ID before the company is registered.
- Company details. The company’s name, ACN, registered office and officeholders are recorded with ASIC. Lenders may search this.
- A new ABN for the company, and GST registration if its turnover requires it. See ABN and GST.
- A separate bank account. business.gov.au says companies must have one.
- The company’s own records and tax returns, separate from your personal return.
Your accountant will guide you through the setup. From a lending point of view, the key is that everything lines up: the company name on invoices, the ABN customers pay, and the bank account the money goes into.
Planning a restructure and wondering how it affects a loan you have in mind? Ask a real person in a short, no-credit-check enquiry.
Should you borrow before or after the change?
It depends, and it’s worth planning.
Borrowing just before restructuring can mean the loan is in your personal (sole-trader) name while the business moves to the company. That may need untangling later, and some loans can’t simply be transferred.
Borrowing just after can mean dealing with a lender who sees a brand-new ABN, unless you explain the history well.
A few practical tips:
- Tell your accountant about any loan plans before you set a restructure date.
- Tell any lender you’re talking to that a restructure is planned or has just happened.
- Keep everything from the sole-trader years: statements, BAS, tax returns.
- Move quickly to the new account once the company starts trading, so its statements build up.
What about using property as security?
If you own your home personally and the company is borrowing, the property can still be used as security, with you (and any co-owner) signing as security providers and usually guarantors. Lesson six on borrowing against property explains the options, and property-secured business loans range from $20,000 to $5,000,000.
A restructure checklist for future borrowing
- Accountant consulted on timing and structure
- Director IDs in place before the company is registered
- New company ABN, and GST registration if required
- Separate company bank account opened and in use
- Invoices updated with the company name and ABN
- Sole-trader records saved (statements, BAS, returns)
- A one-paragraph “history of the business” written for lenders
- Any existing loans reviewed: what stays personal, what moves
Myths about companies and borrowing
“A company can’t borrow until it’s two years old.” Many lenders will consider the history of the business as a whole if you explain the restructure and supply records from both structures.
“Once I’m a company, loans have nothing to do with me personally.” Directors usually sign personal guarantees, and lenders check directors’ credit.
“I can keep using my old sole-trader account.” Companies must have their own bank account, and mixing them makes your records much harder for a lender to follow.
“Restructuring will fix a messy credit history.” A new company doesn’t hide the directors’ credit files. Lenders look at the people as well as the entity.
What to tell a lender about your restructure
Lenders appreciate a short, clear note. Something like:
“The business has traded since 2021 as a sole trader. On 1 July 2026 it moved into a company, with the same owner, customers and services. Statements and BAS from both structures are attached.”
That paragraph answers the questions a lender would otherwise have to ask, and it helps your full trading history count. Keep it with your other loan documents so it’s ready whenever you need it. If you’re asked for a company extract, ASIC’s registers let anyone search basic company details for free, so it’s worth checking your own entry is accurate before a lender does. (The dates here are illustrative.)
Growing up, and thinking about borrowing?
Moving to a company is a sign your business is growing. Borrowing as a company is very normal; it just helps to tell the story of your business clearly, from its sole-trader days onward.
Our enquiry takes about a minute. There’s no credit check involved in asking, and we don’t send your details around a pool of lenders. A real person listens to how your business has grown, explains what lenders will want to see from the company and its directors, and walks you through the options in plain English. Please be accurate about your structure and when it changed; it makes a real difference to which lenders fit.
Frequently asked questions
Does my trading history reset when I become a company?
The company has a new ABN, so on paper it's new. Many lenders will look at the business's history as a whole if you explain the change and show records from both structures. Policies vary, so keep everything.
Should I borrow before or after I set up a company?
It depends on timing and purpose. Borrowing in the sole-trader name just before restructuring can create extra paperwork later. Talk to your accountant about the restructure timing and mention it to any lender you're speaking with.
Will I still be personally responsible for company loans?
Usually, yes, through a personal guarantee. A company is separate from you, but lenders commonly ask directors to guarantee small company loans.
Do I need a separate bank account for the company?
Yes. business.gov.au says partnerships, companies and trusts must have a separate business bank account.
What's a director ID?
It's a unique identifier for company directors. ASIC's registration steps say directors must apply for a director ID before a company is registered.
