How to Get a Mortgage When You're Self-Employed in NZ
Self-employed borrowers in New Zealand face one of the toughest lending environments in the world. The compliance overhead is significant, banks scrutinise everything, and "irregular income" gets discounted hard. The good news: with the right preparation and the right lender, self-employed mortgage applications can be just as successful as PAYE applications — sometimes more so.
What banks want to see
For most self-employed applicants the documentation requirements are:
- Two full years of business financial statements (prepared by an accountant)
- Two years of IR3, IR4 (for companies), or IR7 (for partnerships) returns
- Twelve months of business bank statements
- GST returns for the latest two years (if registered)
- Three months of personal bank statements
- ID, KiwiSaver, deposit confirmation as for any other applicant
The two-year history is the dealbreaker for many new self-employed borrowers. Most banks will not lend on twelve months of self-employed income — they want to see a pattern of stability.
How banks calculate self-employed income
Generally banks use the lower of:
- The most recent year's net profit (after add-backs)
- The average of the last two years' net profit
The "add-backs" are non-cash or one-off expenses that can be added back to net profit to arrive at a more realistic cashflow figure. Common add-backs include:
- Depreciation
- Interest on business debt
- Vehicle costs personally drawn
- Home office percentage
- Genuinely one-off expenses
A good accountant who understands lending can prepare your accounts in a way that maximises legitimate add-backs without crossing into anything aggressive.
The structural decision
If you are operating as a sole trader, your business profit is your personal income — simple. If you are operating through a company, the bank generally looks at your salary plus shareholder drawings plus retained company profit, depending on the lender.
The "Look-Through Company" (LTC) structure works well for some borrowers because the income flows through to shareholders' personal returns, making it look more like sole-trader income to the bank.
The wrong structure can cost you tens of thousands of borrowing capacity. The right structure can unlock it.
What to do twelve months before you apply
If you have plans to buy in the next twelve to eighteen months:
- Talk to your accountant about how your returns will read to a lender
- Pay yourself a regular salary instead of irregular drawings (banks love regular salary)
- Avoid taking large company-paid expenses that reduce declared income
- Keep your GST and provisional tax payments current — a missed payment can flag risk
- Keep clear separation between business and personal accounts
The lender choice matters more than for PAYE borrowers
Self-employed lending criteria vary widely between banks. Some banks are conservative and apply heavy discounts; others have specific self-employed programmes that count income more generously. Non-bank lenders sometimes work well for self-employed borrowers with strong cashflow but unusual income structures.
Without an adviser who knows the self-employed lending market, you can easily end up at a bank that is wrong for your situation and conclude (incorrectly) that you cannot borrow at all.
