Documents checklist

Documents you need for a self-employed car loan in New Zealand

When you work for yourself, a lender cannot read your income off a payslip, so it builds the picture from bank statements, tax records and your own paperwork. There is no single national list, because each lender sets its own, but the same handful of documents turns up again and again. Nobody can promise approval, and lenders decide case by case.

The short answer

A self-employed car loan application usually comes down to four groups of paper: who you are, what comes into your bank account, what your tax records say, and what you owe. You do not need a perfect set. Lenders look at the whole picture, and a gap in one place can often be filled by strength in another.

Our general guide to self-employed car loans covers how lenders think. This page is the checklist: each document, what it shows, where to get it and what to do if you do not have it. Fair Finance is a referral service, not a lender and not a broker. One application and one soft credit check go to a panel of approved New Zealand lenders. We are paid by the lender only if a loan settles, and that never changes your rate. Nobody can promise approval.

Why lenders want documents at all

Before lending, a lender must make reasonable inquiries and be satisfied that you are likely to meet the repayments without substantial hardship. Consumer Protection gives examples of inquiries, including asking for evidence of your income and asking about your expenses. The Responsible Lending Code, revised on 31 July 2024, gives guidance on how lenders can meet that duty, and the Financial Markets Authority says lenders must keep records of the inquiries they made.

For an employee, the payslip does most of the work. For you, the lender has to build the same answer from other evidence. That is why the paperwork is longer, and why a tidy folder helps you.

ID and address

Every lender checks identity. A current driver licence is the usual choice, and a passport also works. Proof of address is typically a recent utility bill, a tenancy agreement or a bank letter. These are the quick wins: if yours are expired or in an old name, fix them first.

Bank statements

Bank statements are the backbone of most self-employed applications, because they show money actually arriving.

Length. Three to six months is common, and longer helps if your work is seasonal or uneven. Some lenders ask for a particular number of months, so confirm before you pull them.
Which accounts. Give the account your income is paid into. If you have more than one business account, or you move money between business and personal accounts, include them all so the lender can follow it.
What the lender reads. Deposits, regular outgoings like rent and other loans, and anything that looks like gambling, overdraft use or dishonoured payments. Tidy up what you can before applying. Our page on soft credit checks explains what happens to your credit file at the early stage.
Cash. Only what you can show counts. If part of your income is paid in cash and goes into the account, it should be recorded and declared. Inland Revenue says to record every job and declare every dollar.

Tax records

Tax paperwork gives the longer view that a few months of statements cannot.

IR3. Inland Revenue says you need to file an individual income tax return if you received more than $200 in income it has not been told about, which covers most sole traders. The return is due on 7 July unless you have a tax agent or an extension of time. Completing it in myIR is usually faster.

Notice of assessment. After you file, Inland Revenue sends a notice confirming receipt and showing any refund or tax owed. A lender may ask for it as proof the return went in.

GST returns. You must register for GST if you carry out a taxable activity and your turnover was at least $60,000 in the last 12 months, or you expect it to be in the next 12. You can register voluntarily below that. If you are registered, your GST returns show turnover period by period.

Provisional tax. Inland Revenue says you are a provisional taxpayer if the residual income tax on your last return was more than $5,000. A lender may ask what you set aside for it, and so should you: tax money is not spare money. We cannot give tax advice, so check ird.govt.nz and ask an accountant how this applies to you.

Inland Revenue also says you should keep records of all your sales and expenses, cash and non-cash, for at least seven tax years, along with your bank records. Those records are also what you will hand to a lender.

Accountant’s financial statements or a profit and loss

If you have an accountant, ask for the latest financial statements or a profit and loss for the current year. They show income less costs, which is what the lender needs. A short letter from your accountant confirming your income and how long you have been trading can also help. If you use accounting software and no accountant, a profit and loss report for the year to date is better than nothing, though a lender may value an accountant’s sign-off more.

Invoices, contracts and your order book

Documents that show where the work comes from help a lender judge whether the income will continue. That includes recent invoices, a repeat client list, signed contracts, or a letter confirming ongoing work. For contract workers, the length of the contract matters. See car finance for contractors for how lenders read it.

Business or personal purpose

Lenders may ask what the vehicle is for. Consumer Protection says the Credit Contracts and Consumer Finance Act covers credit for personal use, while business or investment lending is outside it except for protection against oppressive behaviour. Lenders may ask you to declare the purpose. Answer honestly, and if the car will be used both ways, say so. Our page on business vehicle finance explains the difference.

What to do if something is missing

Most people are missing something. These are the common gaps.

No tax return yet. If you have just started, or you have not filed, a lender cannot see a year of returns. Bank statements, invoices and an accountant’s letter can fill part of the gap. See car finance for the self-employed under two years.
Late filing. If a return is overdue, get it filed first. A lender can hardly rely on tax records that do not exist.
Mixed accounts. Move your income into one account for a few months so the pattern is clear.
Thin or uneven income. Our page on car finance with variable income explains how lenders average it.
A poor credit file. See car finance with defaults and read all three reports before you apply.
Cash that never reached the bank. If it was never recorded, it cannot be counted as income, and you should talk to an accountant about declaring it.

A lender may offer a lighter paper route sometimes called “low doc”. We could not find a standard national definition, so do not assume it means fewer rules. Ask the lender exactly which documents it accepts and in what combination.

A worked example (illustrative numbers only)

Say a sole trader gives a lender six months of statements for the account their income is paid into. The deposits look like this.

Month	Deposits
1	$5,200
2	$4,100
3	$6,300
4	$3,900
5	$5,500
6	$4,800
Total	$29,800

The average is about $4,970 a month. The lender then subtracts business costs. If fuel, materials, phone and insurance come to $1,900 a month and the person sets aside $500 for tax, about $2,570 a month is left, before rent, food and other debts. A $14,000 loan at an illustrative 20% over four years would be roughly $424 a month. The lender asks whether that fits after everything else.

The figures are made up to show the method. Real lenders use their own methods, and some will look at your lowest months instead of the average. The repayment calculator lets you test your own loan.

Red flags

Anyone asking you to alter or doctor documents. Never do it. Statements must be genuine.
A promise of approval before anyone has seen your records. Nobody can do that.
A fee before the loan settles. Be wary of any upfront payment.
A request for your online banking login. Lenders should not need it. Statements can usually be provided as PDFs or through a secure tool, so ask what is used.
A weekly price with no total. Ask for the total repayable and every fee in writing.
Pressure to hurry. A real offer will still be there tomorrow.

How Fair Finance helps

The lender decides case by case, and may ask for documents beyond this list. We are paid by the lender only if a loan settles, and that never changes your rate. Use the quick check to start. Our guide on what you need to apply covers the general paperwork.

Common questions

What documents do I need for a car loan if I am self-employed in NZ?

Expect to give photo ID, proof of address, bank statements for the account your income goes into, and some tax or accounting records such as your latest IR3 and notice of assessment. GST returns, invoices and an accountant's financial statements help if you have them. The exact list depends on the lender, so ask which documents it accepts.

How many months of bank statements does a self-employed car loan need?

Three to six months is common, and longer helps if your income is seasonal or uneven. A longer record lets the lender see your quiet months as well as your busy ones. Some lenders use a different period, so check before you gather anything.

Can I get a car loan without tax returns?

Sometimes, if you can show your income another way, for example with bank statements, invoices and an accountant's letter. It depends on the lender and how long you have been trading. A lender must still make reasonable inquiries, so it will want some solid evidence of what you earn.

Should I use my business or personal bank account statements?

Give the account your income actually lands in, and if money moves between business and personal accounts, give both so the lender can follow it. Mixing the two makes the picture harder to read. A clear transfer from business to personal for your drawings helps.

Does the lender look at my gross or my net income?

Lenders are usually interested in what is left after your business costs, because that is what pays the loan. Expect questions about fuel, materials, wages, tax and other outgoings. Keep your records tidy so the numbers are easy to confirm.

Do I need an accountant to apply?

You do not need one in every case, but an accountant can prepare financial statements, file your returns and confirm your income in a letter, all of which strengthen an application. If you do not have one, bank statements and a tax return you filed yourself still count as evidence.

See your repayments, then get a fair rate.

One application, one soft credit check, no obligation. We match you to the lender most likely to give you a fair go.
