TL;DR: Sole trader or company doesn't decide whether you get finance — your numbers do. But it changes who borrows, who's on the hook, and how the lender reads your books. A company adds a thin legal wall, but you'll almost always still sign a personal guarantee. Get the structure right with your accountant before you borrow, not after.
---
One of the most common questions we get from tradies isn't about rates or deposits. It's this: *'Should I be a sole trader or set up a company — and does it change what I can borrow?'*
Fair question. The short version: your structure doesn't decide whether finance gets approved — your income, your books and your credit do. But it absolutely changes *who* is borrowing, *who's on the hook* if it goes wrong, and *how a lender reads your situation*. Here's the honest walk-through.
First, the big caveat: we're a finance broker, not your accountant. Whether you should be a sole trader or a company is a tax and legal decision, and it depends on your profit, your risk, your family setup and your plans. Get that call from your accountant. What we *can* do is tell you how each one looks from the finance side of the table.
## The one line that explains most of it
A **sole trader** and the business are the same legal person. There's no wall between your money and the business's money. Your IRD number is the business's IRD number. If the business owes, *you* owe.
A **company** is a separate legal person. It has its own NZBN, its own bank account, its own tax return. In theory, the company's debts are the company's, not yours.
That one difference — separate person or same person — sits underneath almost every finance question that follows.
## How lenders assess each one
This is where it gets practical.
**Sole trader.** The lender is really assessing *you*. Your business income and your personal income are one pool. They'll usually want your last year of financials or tax return, plus 90 days of bank statements, and they'll look at your personal commitments alongside the business ones. Because you and the business are the same, the loan is, in a real sense, a loan to you for a business purpose.
**Company.** The lender assesses the *company* — its trading history, its financials, whether it can service the repayments — and then they look at *you* behind it. A brand-new company with no trading history doesn't get a free pass just because "company" sounds more serious. If the company is six weeks old, the lender will lean almost entirely on the directors. An established company with two or three years of clean accounts is genuinely easier to assess, because the numbers tell a story on their own.
New tradies sometimes set up a company thinking it unlocks bigger or easier finance. It doesn't, on its own. A fresh company with no trading history is often *harder* to finance than an established sole trader, because there's no track record to assess — so the lender falls back on you anyway.
For both, the same fundamentals win or lose the deal: clean books, a sensible income trail, and a clear story about how the asset earns. If you want to get those right before you apply, [getting your books finance-ready](/blog/getting-your-books-finance-ready) is the place to start.
## Liability — the bit that actually matters when things go wrong
This is the real reason structure exists, and it's worth being straight about.
As a **sole trader**, there's no separation. If the business can't pay a debt, creditors can come after your personal assets — your savings, sometimes your home. The upside is simplicity. The downside is you carry the full risk personally.
A **company** gives you what's called limited liability — the idea being that if the company fails, your personal assets sit behind the wall. That protection is real, and it's a genuine reason a lot of growing trade businesses incorporate as they take on bigger jobs and bigger risk.
But here's the catch every tradie needs to hear before they get comfortable.
## The personal guarantee — why the wall has a door in it
When a small company borrows, the lender knows the company might have few assets of its own. So they ask the director to sign a [personal guarantee](/glossary/personal-guarantee) — a promise that *you'll* personally cover the debt if the company can't.
The moment you sign that, the limited-liability wall has a door in it, and your name is on the door. For that specific debt, you're personally on the hook just like a sole trader would be.
For most small trade companies, a personal guarantee is standard — so the company structure protects you from a lot of things, but usually not from the finance you signed for.
This isn't a trick or a gotcha — it's normal, and it's how small-business lending works the world over. But too many tradies set up a company believing they're fully shielded, then sign a personal guarantee on the finance without reading it. Know what you're signing. A guarantee can outlast the asset, and it can follow you to the next lender.
## Tax and admin trade-offs (high level — your accountant decides)
We'll keep this deliberately broad, because this is firmly accountant territory.
| | Sole trader | Company |
|---|---|---|
| Setup and admin | Simple, cheap, fast | More setup, annual filing, more paperwork |
| Tax | Profit taxed at your personal rates | Company tax rate on profit (current rate — check IRD) |
| Liability | You're personally exposed | Limited, but personal guarantees pierce it |
| Separating money | Hard — it's all one pool | Cleaner — separate accounts and records |
| Looks to lenders | Loan to you, business purpose | Loan to company, you behind it |
A rough rule of thumb that accountants use: while profits are modest, a sole trader is often simpler and just as efficient. As profit grows, and as risk and the number of staff grow, a company starts to make more sense — for tax flexibility, for liability, and for looking more established to lenders, suppliers and clients. But the crossover point is different for everyone, and there are good reasons it can go either way. **Confirm your tax position with your accountant or IRD — don't take a finance article's word for it.**

## What this means when you're financing a ute or some plant
A few practical takeaways from the finance side:
- **Either structure can get finance.** The decision rarely lives or dies on sole-trader-versus-company. It lives on your numbers.
- **A new company won't impress a lender on its own.** If you've just incorporated, expect the lender to assess you personally for a while. The structure catches up once the company has a trading history.
- **Read every personal guarantee.** Whether you're a sole trader (no wall at all) or a company director who's signed a guarantee (a door in the wall), understand exactly what you're personally liable for.
- **Keep the business money separate** if you possibly can — even as a sole trader with a dedicated account. Clean, readable books make every finance application faster, and they make your accountant cheaper.
- **The CCCFA angle is the same either way.** Genuine business-purpose finance is largely outside NZ's consumer responsible-lending rules, and you'll sign a business-purpose declaration regardless of structure. There's [more on the CCCFA here](/blog/does-the-cccfa-apply-to-my-business-loan).
## The honest order of operations
1. Talk to your accountant about structure *before* you go shopping for finance. Get it right at the start — changing structure mid-stream is messy.
2. If you're just starting out, don't set up a company purely to look serious to a lender. It rarely helps, and it adds admin. Our [starting a trade business finance guide](/guides/starting-a-trade-business-finance-guide) walks through the early calls.
3. Whatever structure you land on, get your books clean and your bank account separated.
4. When you apply, read the personal guarantee like it's the most important page in the contract — because for your risk, it is.
Structure is one of those decisions that's cheap to get right early and expensive to fix late. If you want to talk through how your setup looks from a lender's side — and what it means for the finance you're chasing — [book a call with a real broker](/book-a-call) or [ask us a question](/help).
