Self-Employed Mortgage NZ — Borrowing When You Work for Yourself

Getting a mortgage when you’re self-employed in New Zealand is harder than for PAYE employees — but it’s very achievable. The challenge is income evidence. Banks need to be confident your income is stable and sufficient to service the loan, and the standard payslip doesn’t exist for self-employed borrowers.

Who This Guide Is For

“Self-employed” covers a range of situations:

Sole traders — running your own business without a company structure
Company directors — owning and working in your own company
Contractors — working under contract (fixed-term or ongoing) without being an employee
Freelancers — project-based or irregular work
Partners in a partnership — income flows through a partnership

Each has slightly different income evidence requirements.

The Core Challenge: Proving Your Income

For PAYE employees, income is simple: payslips confirm a consistent amount. Banks can verify it with an IRD employer earnings summary.

For self-employed borrowers:

Income may vary month to month, or year to year
Profits can be reduced deliberately (expenses claimed) to minimise tax — the same tax minimisation that saves money on income tax reduces the income figure banks use for assessment
Business income may flow through a company (as dividends and salary) rather than as personal income

Banks don’t care what your gross revenue is — they care about your net taxable income as documented.

Documents Required

2 years is the standard

Most mainstream NZ banks require at least 2 years of self-employment history, evidenced by:

Document	Description
Financial statements	Prepared by a chartered accountant; shows profit and loss, balance sheet
Income tax returns	Filed with IRD for each of the last 2 years
Notices of assessment	IRD’s confirmation of your tax position for each year
Business bank statements	3–6 months of business account statements
Personal bank statements	3–6 months showing personal financial management
IR3 return	Your individual income tax return

What if I’ve been self-employed for less than 2 years?

This is a significant challenge with mainstream banks. Options:

Wait until you have 2 years of records — painful but often the cleanest path
Use a non-bank lender — non-banks like Avanti Finance, Pepper Money, or Liberty Financial often accept 1 year of records, at higher rates
Apply as a PAYE employee if possible — if you’ve returned to employment, some banks will assess a mix of self-employed and employed income

How Banks Assess Self-Employed Income

Banks typically:

Take your last 2 years of net profit (after business expenses, before personal drawings)
Average the two years — or take the lower figure if income is declining
Adjust for non-recurring items (if the financial statements include one-off income or expenses, the bank may normalise these)
Add back some non-cash deductions (depreciation is often added back, as it doesn’t represent actual cash outflow)

The add-back rule: If your accounts show $80,000 net profit but $15,000 of depreciation, the bank may assess $95,000 in income ($80,000 + $15,000 depreciation add-back). Talk to your accountant and broker about what add-backs are available.

The Tax Minimisation Problem

Many self-employed people legitimately minimise their taxable income through:

Claiming business expenses
Maximising depreciation
Routing income through family trusts or companies

This is legal and sensible from a tax perspective — but it can significantly reduce the income figure banks see for mortgage assessment.

Example:

Business gross revenue: $180,000
Legitimate business expenses claimed: $85,000
Net profit (bank sees): $95,000
Borrowing capacity at 6× DTI: $570,000

If expenses were lower (or structured differently), net profit would be higher and borrowing capacity greater. This is why some self-employed people find their borrowing capacity is much lower than their lifestyle or revenue would suggest.

Strategies:

Speak to your accountant 1–2 years before applying: plan for clean financials that maximise net income for the 2 years before application
Avoid claiming personal items through the business in the years leading up to application
Consider the trade-off: tax savings vs mortgage capacity

Company Directors: Using Dividends and Salary

If your income comes from a company you own, banks typically assess:

Your personal salary drawn from the company (confirmed by payslips)
Dividends paid to you (confirmed by dividend resolutions)
Sometimes: the company’s net profit (as evidence of business health and your ability to draw more if needed)

Banks differ on how they treat company profits that haven’t been paid out as salary or dividends. Some include them; most don’t. Maximising your drawable income from the company in the 2 years before application (even if it means more personal tax) improves your assessed income.

Contractors: Permanent vs Variable

Fixed-term contractors with a current contract: Banks often treat contractors with a current contract and a track record of renewal similarly to PAYE employees. Evidence required: the current contract, plus last 2 years of income evidence (tax returns or bank statements).

Variable/freelance contractors: Income that varies significantly year to year is harder to assess. Banks typically average 2 years or take the lower year. Non-banks may be more flexible.

Which Lenders Are Best for Self-Employed Borrowers?

Mainstream banks: All major NZ banks (ANZ, ASB, BNZ, Westpac, Kiwibank) lend to self-employed borrowers with 2+ years of records. Some are more flexible than others in how they assess add-backs and company income. Using a broker is particularly valuable here — they know which bank’s credit team will treat your specific situation most favourably.

Non-bank lenders: Avanti Finance, Resimac, Pepper Money, and Liberty Financial often accept 1 year of financials and have more flexible income assessment. Rates are higher (typically 0.5%–2.0% above bank rates). These are useful for:

Borrowers who haven’t yet built 2 years of records
Complex income structures
Post-decline situations where a mainstream bank has said no

Tips to Maximise Your Chances

Use a mortgage broker — self-employed mortgages are exactly the situation brokers add the most value. They know which lender’s policies suit your income structure.
Work with a good accountant — ensure your financials are prepared by a chartered accountant (banks view accountant-prepared statements as more credible than self-prepared ones).
Start planning 2 years early — if you know you want to buy in 2 years, talk to your accountant now about financial statement presentation.
Separate personal and business finances — clean separation between personal and business bank accounts makes income evidence clearer and applications smoother.
Don’t take on new debt before applying — car loans, credit cards, and business finance all affect your borrowing capacity.
