Key Takeaways
Getting a self-employed home loan in NZ comes down to showing a lender reliable income, a documented deposit and a budget that works after all your commitments. This guide explains how lenders assess business income, the documents you will need for your structure, and the steps from pre-approval to settlement.
- Lenders generally assess self-employed income on historical earnings, so filed accounts and tax returns carry the most weight.
- Many lenders ask for two years of financial statements, though some accept a shorter history with good evidence.
- The documents you need depend on whether you are a sole trader, partner, company shareholder or contractor.
- Reserve Bank LVR and DTI limits and CCCFA affordability checks apply to self-employed borrowers the same way as everyone else.
- Pre-approval is conditional: the lender will check the property and your latest finances before final approval.
How lenders assess a self-employed home loan application
A lender's core question is whether you can keep making repayments without substantial hardship. For an employee that starts with a payslip. For a business owner it starts with your accounts, tax returns and bank statements, read together to work out what income is reliably available to you.
Who counts as self-employed
Lenders usually treat you as self-employed if you are a sole trader, a partner in a partnership, a shareholder who works in and draws income from your own company, an independent contractor, or someone whose income comes through a trust you control. Some lenders also treat employees who own a significant share of their employer this way. Your structure decides which documents are relevant and how your income is calculated.
Trading history
Many lenders want two years of financial statements so they can see whether profit is stable, rising or falling. Some will consider one year, or even less, where you have worked in the same industry before, have firm contracts, or can show steady income through bank statements. A shorter history usually narrows your lender options rather than ruling you out.
How your usable income is worked out
Lenders start from net profit, not turnover. Depending on policy, some add back certain non-cash or one-off expenses, such as depreciation or a clearly non-recurring cost, and some may count company profit you have left in the business. Where income has fallen, expect the lower year to be used. Where income has risen sharply, a lender may average the years or ask for evidence the increase will last.
Affordability checks
Under the Credit Contracts and Consumer Finance Act (CCCFA), lenders must make reasonable inquiries into your income and expenses before lending. They will look at living costs, existing debts and how repayments would hold up at a higher test rate. The FMA has regulated consumer credit since 1 July 2026, but the core affordability obligation on lenders is unchanged.
Documents you need for a self-employed home loan
Every lender has its own checklist, but the core documents are similar. Gathering them early lets you spot gaps, such as accounts not yet finalised or tax returns not filed, before they hold up an application.
| Business structure | Income evidence lenders commonly ask for | Extra items that may be needed |
|---|---|---|
| Sole trader | Financial statements and individual income tax returns (IR3) | GST returns if registered, business bank statements |
| Partnership | Partnership accounts and return (IR7), plus your IR3 | Partnership agreement showing your profit share |
| Company shareholder | Company financial statements and return (IR4), plus your IR3 | Shareholder salary details, current account balance, company bank statements |
| Contractor | Tax returns and invoices or contracts | Evidence of contract length and payment history |
Financial statements and tax returns
Accountant-prepared financial statements are the backbone of most applications. If your latest year has ended but the accounts are not finished, ask your accountant for a timeframe and consider whether management accounts could bridge the gap. Make sure the figures in your statements and tax returns line up, or be ready to explain why they differ.
Your position with Inland Revenue
Lenders often want to see that your tax returns are filed and that you do not have overdue tax, or that any arrears are under an agreed arrangement. A statement from myIR can help show this. If you are GST registered, which is required once turnover exceeds $60,000 a year according to Inland Revenue, recent GST returns can help show current trading.
Bank statements and debts
Expect to provide recent personal and business bank statements, plus details of every loan, credit card, vehicle finance and buy now pay later account. Include business debts where you have signed as guarantor. Leaving something out can delay approval or cause a decline if the lender finds it later through a credit check.
How much you can borrow when self-employed
Your borrowing limit is set by whichever of these three is smallest: what the lender's affordability test allows, what the Reserve Bank's limits permit, and what your deposit supports. Online calculators give a rough idea, but your assessed income is what matters.
Deposit and LVR
Under the Reserve Bank's settings from 1 December 2025, banks can make up to 25% of new owner-occupier lending to borrowers with less than a 20% deposit. For investment property the threshold is a 30% deposit, with up to 10% of new investor lending allowed below it. A low-deposit loan is possible but rationed, so a strong application matters more.
Debt-to-income limits
Since 1 July 2024, banks can make only 20% of new owner-occupier lending above a DTI of six times gross annual income, and 20% of investor lending above seven times. The Reserve Bank's DTI explainer notes that credit cards count at their limit, not their balance, and that banks generally assess self-employed income on historical earnings. Construction loans and new homes bought from a developer are exempt.
Using KiwiSaver and first home support
If you are buying your first home and have been a KiwiSaver member for at least three years, you may be able to withdraw your savings except $1,000, which must stay in your account. You apply through your provider, and funds are paid to your lawyer for settlement. Our page on the KiwiSaver first home withdrawal explains the process. Kāinga Ora's First Home Loan may also be an option for eligible buyers, so check current criteria with Kāinga Ora as settings can change.
Loan options for self-employed borrowers
Most self-employed people borrow on standard terms from a bank. When standard evidence is not available, there are other routes, usually at a higher cost.
Full-documentation loans
A full-documentation loan relies on your financial statements, tax returns and bank statements. If your accounts are current and show steady income, this route generally gives you the widest choice of lenders and loan structures, including fixed, floating and split loans.
Low-doc and alternative-documentation loans
Some non-bank lenders offer loans that rely on other evidence, such as accountant letters, bank statements or GST returns, where full accounts are not available. These loans still require affordability checks under the CCCFA. They often come with higher costs, a larger deposit requirement or extra fees, so they are usually a short-term solution before refinancing to a mainstream lender once accounts are available.
Choosing a structure that suits uneven income
If your income moves around, think about structure as well as price. A floating or revolving portion can let you pay down debt in strong months, while a fixed portion gives certainty on the core repayment. Use our loan repayment calculator to test repayments at different loan amounts.
How to apply for a self-employed home loan, step by step
A planned application moves faster and is less likely to stall over missing information. These are the usual stages.
- Get your accounts current. Finalise the latest financial statements and file any outstanding tax returns.
- Tidy your bank accounts. Keep business and personal spending separate and be ready to explain large transfers.
- Work out your budget. List household costs, debts and the deposit you can document.
- Choose the right lender. Match your structure and trading history to lender policy before applying.
- Apply for pre-approval. Submit the documents in one organised pack with a short explanation of anything unusual.
- Find a property and get final approval. The lender checks the property, any valuation and your latest finances.
- Settle. Your lawyer handles the legal work, and the lender pays the funds on settlement day.
What pre-approval does and does not confirm
Pre-approval tells you a lender is willing to lend up to a certain amount, subject to conditions. Those conditions usually include a suitable property, satisfactory valuation where needed, and no material change in your income or debts. Pre-approvals expire after a set period, so check the date and tell your adviser straight away if your business circumstances change.
Final approval and settlement
Once you have a property, the lender confirms the purchase details and may ask for updated statements. You will usually need house insurance in place before settlement. Read the loan documents carefully, check the structure matches what you agreed, and leave enough time between approval and settlement for your lawyer to do their work.
Why self-employed applications stall
Most delays are avoidable. The common causes are:
- Financial statements for the latest year not yet prepared.
- Overdue tax returns or unexplained tax arrears.
- Profit falling between years with no explanation.
- Personal and business spending mixed in the same account.
- A deposit that cannot be traced to its source.
- Changing how you pay yourself just before applying.
If you are planning a change to your business structure or how you draw income, talk to your accountant and adviser first. A change made for tax reasons can make your income harder for a lender to assess in the short term.

Conclusion
A self-employed home loan is very achievable when your accounts are current, your tax is in order and your deposit is documented. Lenders want to see a clear, consistent picture of income that has been earned and filed, not just a strong recent month.
Start preparing several months before you plan to buy, keep business and personal finances separate, and match your application to a lender whose policy suits your structure. That preparation is what turns a complicated file into a straightforward one.
