Introduction
As the end of the financial year gets close in New Zealand, it is a good chance for people here to sort out their money matters. The financial year can feel hard for many, as there are a lot of papers and things to do before you get to the end. Still, if you plan a little early, you can handle your tax obligations well and feel sure about what you need to do. This guide will help you understand all you need to know about the end of the financial year in New Zealand. It talks about the key dates and the main steps to take. You will find it much easier to get ready before the deadlines come.
Understanding the End of Financial Year (EOFY) in New Zealand
The end of the financial year in New Zealand is an important date. People often call it EOFY. It is the last day of the tax year, which starts on 1 April and ends on 31 March of the next year. During this time, people and businesses need to look over their accounts. They also need to show Inland Revenue, or IRD, what they have earned.
You can think of the end of the financial year as a finish line for your money reports. At this time, you add up your income. You list your expenses too. This helps you see your whole tax position. If you want an easier tax time, it helps to understand first what the financial year means in New Zealand.
Key Dates for EOFY 2026 and Why They Matter
Knowing the key dates for the end of the financial year is crucial for staying on top of your obligations and avoiding penalties. The financial year in New Zealand officially ends on 31 March. This date is important because it finalises the 12-month period for which you need to report your income and expenses.
Once the financial year end passes, a series of other important deadlines follow. These due dates relate to filing your tax return and paying any tax you might owe. For those filing their own tax return for the 2025/26 financial year, the deadline is 7 July 2026. If you use a tax agent, you often get an extension of time, with the due date pushed to 31 March 2027.
Here are some of the most important dates to remember:

How the New Zealand Financial Year Differs from Other Countries
While many countries have their financial year the same as the calendar year, New Zealand does it in a different way. In New Zealand, the tax year starts on 1 April and ends on 31 March. People call this a March balance date. This means that the next financial year will always begin on 1 April.
This way of working is not the same as in countries like Australia, where their financial year ends on 30 June. In the United Kingdom, the financial year end is on 5 April. The United States, for many people, has the financial year for tax purposes ending on 31 December, which is the same as the calendar year.
The timing of New Zealand’s financial year affects when tax returns must be filed or when payments need to be made to Inland Revenue. This setup is made to help spread out the work for both regular people and Inland Revenue. It is good to understand this, especially if you are involved with money or taxes in other countries as well.
Why the End of Financial Year Is Important for Kiwis
The end of the financial year is not just another date you see on the calendar. It is a key time for every Kiwi taxpayer. This is when you add up your earnings and what you spent, making sure you have paid the right amount of tax. For many people, it can lead to a tax refund. For business owners, this step is even more important for planning their money matters and sorting out tax obligations.
Doing this each year keeps the tax system working well, as it helps everyone pay their fair share. It is also a good time to check your finances and make plans for the next year. Now, let’s look at the way this can affect different types of taxpayers.
Impacts on Individuals, Sole Traders, and Businesses
The end of the financial year is important for everyone, but it can look different based on how you earn and how you work. If you are a PAYE employee, the process is mainly automatic. Inland Revenue will work out if you get a refund or if you need to pay more.
If you are a sole trader or a business owner, the financial year end needs more attention. This time is very important for tax purposes. You have to go over your total income and all your business expenses. Doing this helps you look after cash flow and see how your business has gone in the last year.
Here’s a quick breakdown of the impacts:
-
Individuals (PAYE): Your employer has already taken out the tax for you. The financial year end is when Inland Revenue checks if the right amount was paid.
-
Sole Traders: You have to work out your total income, claim your business expenses, and put in an IR3 tax return.
-
Business Owners: You need to finish your financial statements, check on your business performance, and meet extra rules like FBT or GST.
Key Tax Obligations Tied to EOFY
The end of the financial year puts your main tax obligations in the spotlight. If you have income that is not taxed yet, like money you get from working for yourself or from renting out property, you need to file an income tax return. This return shows your money-in and money-out for the tax year.
You also need to make sure you pay your income tax. This might be a last payment for tax from last year, or another payment called provisional tax for this year. Provisional tax is a way of paying your tax as you go. This helps you manage a big tax bill when the year ends.
Your main tax obligations include:
-
Filing an income tax return that is right (for example, the IR3 for sole traders).
-
Paying any left-over income tax from last financial year.
-
Making provisional tax payments if you need to.
-
Filing and paying for all gst returns for the year.
What You Need to Get Started for EOFY Preparation
Getting ready for the end of the financial year does not have to feel rushed. The best way is to be prepared. You can start by putting all your tax records in order. Make sure your financial information is fresh and correct. This means you need everything, like income details and receipts for business expenses, to hand.
When you keep all the information in one place, you make it easy for yourself to finish the tax return or to give your accountant what they need. You will also see how your business is doing before you get ready to finish your financial statements. Now, let’s look at the documents and tools you will need.
Essential Documents to Gather Before 30 June
To get ready for your tax return, you will need to gather different financial records. If you have these documents with you before you start, it will save you both time and stress. These records are important as they show what income you get and the business expenses you want to claim.
Bank statements are a good place to start. They show all the money going in and out of your accounts. You should also have a summary of your income from different sources. If you run a business, now is the right time to bring together the records you need for your financial statements. These can help you show your business performance for the year.
Here’s a list of the main documents to collect:
-
Bank statements for all business and personal accounts.
-
A summary of all income, including PAYE, self-employment, and rental income.
-
Receipts and invoices for all business expenses you plan to claim.
-
Details of any asset purchases, like equipment or vehicles.
-
Payroll records if you have employees.
-
Logbooks for vehicle use or records for home office expenses.
-
Donation receipts if you want to claim tax credits.
Tools and Resources to Make EOFY Easier
You do not have to take care of the end of the financial year by yourself. There are many tools and resources out there that can make things simple for you. These help you keep your financial records right all through the year. When you use them, tax time does not have to be so hard.
Modern accounting software is one of the best things for business owners to use. It will do a lot of the record-keeping for you, keep track of your income and spending, and can also help with GST returns. This way, when the end of the financial year is here, you can get all the information you need much more easily. If you are feeling unsure or need help, getting some professional advice is a good idea.
Have a look at these resources:
-
Accounting software: Tools like Xero, MYOB, or Hnry will help you keep records well.
-
A tax agent: A tax agent can get your tax return ready and file it for you. This makes sure you do things right and might help you find more things you can claim.
-
Inland Revenue’s website: The IRD site gives you guides, calculators, and safe online tools using myIR.
-
Business mentors or advisors: They can give you advice on how to plan and manage money for your business.
Step-by-Step Guide: How to Prepare for EOFY in New Zealand
Getting ready for the end of the financial year is easier when you break it down into small steps. If you follow a simple plan, you will be able to go over your records, sort out your tax filing, and not miss anything important. This way, you do not have to feel stressed out by all the things you need to do.
It does not matter if you are someone on your own keeping track of business expenses, or an employer running payroll, having a clear plan will help a lot. This easy-to-follow guide walks you through the main things you need to do to get ready for the end of the financial year and sort your tax return.
Step 1: Review Your Financial Records and Transactions
The first step to get ready for EOFY is to look back at your financial records from the year. You need to check all your transactions and make sure they are put in the right groups. Ask yourself if you got all the business income you should have. Also check that every expense is listed.
This review is important for tax compliance. You need accurate records for good financial statements and your tax return. Take time to check your bank records, invoices, and receipts. Try not to miss anything. Now is also a good time to follow up on any money still owed to you.
Having a full and accurate set of financial records helps make tax time less stressful. It gives you a real look at your financial health. You can see where your money came from and where it went, which will help you with planning for your business in the future.
Step 2: Reconcile Bank Accounts and GST Returns
Once you have gone through your transactions, the next thing to do is to check your bank accounts. This means you need to match what you have in your accounting records with your bank statements. You want these to line up just right. Doing this helps make sure your financial records are right and show where the money is.
If you are signed up for GST, you need to make sure all the GST returns for the year are done. These returns have to be in line with your financial records too. The amounts you put on your GST returns should be the same as the income and spend numbers in your accounting system for each taxable period. If something does not match up, you must work out why and put it right.
To check things well, you should:
-
Check the closing number at the end of one month’s bank statements is the same as the opening number at the start of the next.
-
Go through and tick each transaction in your records when you see it in your bank statements.
-
If you notice a difference, look into it and fix it straight away.
-
Make sure the total sales and buys for the year are the same as the amounts you put in your GST returns.
Step 3: Check Payroll and HR Compliance
For employers, the end of the financial year is a key time to take care of your payroll obligations. It is important to check your payroll records. Make sure everything is right and follows the rules. Check if all employee details are correct. See if you have done all your payday filing over the year.
You should also use this time to look over your employee records. Are the contact details, bank accounts, and tax codes up to date? You need all the right information to run payroll well and to give your employees the correct payments at the end of the financial year.
Your end of the financial year payroll checklist should have:
-
Check all payday filing for the year is done right and on time.
-
Go over and update all employee records.
-
Work out and keep track of any fringe benefit tax if you give perks to your staff.
Step 4: Finalise Income and Expense Statements
With your records checked and your accounts matched up, you can now finish your main financial statements. For your income tax returns, the two most important statements are the profit and loss statement (some people call this the income statement) and the balance sheet.
The profit and loss statement shows your income and business expenses for the financial year. It also tells you if you made a profit or a loss. The balance sheet gives a quick look at where your business stands on the last day of the financial year. It lists your assets, what you owe, and what is yours.
These finished financial statements are helpful for more than just tax purposes. They can help you see how your business is going, spot what works, and make good choices for the next year. Make sure you put all business expenses in the right place in your records so you get all the income tax deductions you can.
Step 5: Lodge Your Tax Return with Inland Revenue
The last thing you need to do is get your tax return ready and send it to Inland Revenue (IRD). If you have income that did not have tax taken at the start, like money from self-employment, you must do an individual income tax return (IR3). This will show your total income and the expenses you want to claim. You need to send this to IRD.
You can send your income tax return online with myIR. Some of your income details may already be filled in for you. Or, you can get a tax agent to do it and send it in for you. A tax agent can also ask for an extension of time, so you get until 31 March of the next year to file.
Remember the key dates. If you do the filing yourself, your return is due by 7 July. When you send it in, the IRD will tell you if you need to pay more tax or if you will get money back. It is important to file your income tax return on time to stay away from any penalties. Make sure you do this last step.
Common Mistakes to Avoid at EOFY in NZ
Getting through the end of the financial year can be hard. It is easy to make mistakes that may cost you time or money. If you know what the common problems are, you have a better chance to avoid them. Things like missing deadlines or making mistakes in your tax return can lead to fees and extra stress.
Good tax compliance means you need to get the little things right. You have to keep your records in order, know what you need to do, and try not to wait until the last minute. Here are some of the biggest mistakes Kiwis make at the end of the financial year, and how you can stay away from them.
Overlooking Key Deadlines and Missing Documents
It is easy to make mistakes with your tax return, but some can end up costing you a lot. One big problem is forgetting key dates. Tax deadlines do not move, and if you miss them, you may have to pay penalties for filing late and interest for any unpaid tax. To avoid this, make sure you mark all the important dates in your calendar at the start of each year. That way, you will be ready for what is coming.
Another mistake is not having all your financial records. Completing a tax return without the right documents is like baking a cake without a recipe—you are guessing, which often leads to mistakes. If the IRD asks for proof, you might get into trouble. Keeping accurate records all year will save you from these issues.
To stop these mistakes, you should:
-
Use a calendar to track all tax deadlines.
-
Keep all your financial records, like receipts and invoices, in one organised place.
-
Don’t wait until the last minute to get your documents together.
-
Reconcile your accounts often, not just at the end of the year.
-
If you do not know what to do, ask a professional for help as soon as you can.
Misunderstanding Tax Deductions and Allowable Expenses
Misunderstanding what you can and can’t claim as a business expense can be a big cause of mistakes on your tax return. If you claim things you should not, you could face an audit and possibly have to pay extra fees. But if you do not claim all the business expenses you should, you end up paying more tax than you have to.
The main rule is that an expense has to relate to earning your business income if you want to claim it. But some things, such as home office expenses or running costs for your car, have some special rules, which can make things confusing. That is why you need to know the difference between private costs and business expenses that you can claim.
Things that often confuse people are:
-
Claiming 100% of an expense, like your phone or vehicle, even though it is also used for personal stuff.
-
Trying to write off big items straight away, like when you buy a new computer, instead of working out wear and tear over time.
-
Not keeping good records like a logbook or receipts to prove your expenses.
-
Getting the home office expenses wrong by not working out the proper business share for your house bills.
Special EOFY Rules for Sole Traders and Small Businesses
If you are a sole trader or run a small business in New Zealand, there are some rules that you need to know at the end of the financial year. You need to take care of your own tax matters. This means you must keep track of your business income and file the right tax return.
This can feel hard if it is your first year of business. You have a lot of new things to learn and take care of. It is very important to know these rules because they help you stay on track with the law and manage your money well. The next parts will talk about what you need for your tax return and other tax things you should know at the end of the financial year.
IR3 Tax Return Requirements for Sole Traders
For sole traders, the IR3 tax return is the main form you need to use to tell the IRD about your money for the year. You fill out this tax return by adding all your income, not just your business income. You should also include things like any salary, interest, or dividends you have got.
On your IR3, you also need to give details about your business expenses. If you take away your total business expenses from your business income, you will get your net profit or loss. This number helps work out your income tax. If you make a loss, you can sometimes use it to lower the income on your next tax return.
Key parts of your IR3 return are:
-
A summary of all income from every source.
-
A detailed list of the business expenses you want to claim.
-
An IR3B schedule to show your self-employed income and expenses.
-
A profit or loss statement for your business work.
It is important for sole traders to be clear about business income, business expenses, and loss statement when doing their income tax.
Provisional Tax, Withholding Tax, and GST Considerations
Sole traders often have to handle more than just their main income tax return. Provisional tax is a key one to know about. If you owe more than $5,000 in tax at the end of the year, you will need to pay provisional tax in steps during the next year. This helps you keep on top of your income tax payments.
If you work as a contractor in some industries, you also need to think about withholding tax. Here, your client keeps some tax from your pay and sends it straight to the IRD. You must still add this income to your tax return. You get credit for the tax that has already been paid.
The end of the financial year (EOFY) is also a time to check your GST returns.
-
Make sure all of your GST returns for the year are in.
-
See if you have earned over $60,000. If you have, you must register for GST.
-
Make sure your last GST payment for the period ending 31 March is paid by the due date, which is 7 May.
EOFY Payroll and HR Checklist for Employers
For employers, the end of the financial year is a key time to finish up payroll records and make sure all your HR jobs are done. You need to check that every worker’s details are right and that you have followed all the payroll obligations for the whole year.
This is a good time to go over everything so you can start the new financial year fresh. You should look at payday filing and work out leave balances at this time. By sorting out your payroll and HR now, you stop problems with your team and Inland Revenue. We will now share a checklist of the most important tasks.
Payday Filing and Employee Records
When the financial year ends, one thing that is very important for employers is to make sure all payday filing is done right. With payday filing, you must send pay details to the IRD each time you pay staff. At the end of the year, check again to see that every pay run during the financial year has been sent and is correct.
This is also a good time to go over your employee records and make changes if needed. Doing this helps make sure names, addresses, tax codes, and bank accounts stay correct. It is important to have up-to-date employee records so that taxes and student loan repayments get worked out right. Good records also help your people get the right information when they need it for tax purposes.
To follow the rules, you should:
-
Make sure all payday filing for the financial year is done and given to the IRD.
-
Go over employee records to fix anything that is wrong or no longer up to date.
-
Look at your pay details to see that PAYE, KiwiSaver, and any other things like student loan repayments are taken out the right way.
Calculating Leave, Entitlements, and Final Payments
At the end of the financial year, it is important to sort out employee entitlements. You should check that all leave, like annual leave, sick leave, and alternative holidays, are counted right and show up the right way in your payroll records.
This means you need to look at each employee’s leave history and balances. Are the records for leave that is taken and built up all up to date? It is needed by the law to make sure these balances are correct. It is also important for your financial statements, since leave that is not taken is seen as something your business owes people.
Your year-end leave and payment checklist has to cover:
-
Reviewing and updating the leave balances for every employee in your payroll system.
-
Ensuring that any final payments made to employees who left during the year were calculated correctly.
-
Accurately recording the liability for accrued employee leave in your end-of-the-financial year financial statements.
Where to Find Official EOFY Guidelines and Support
You do not need to handle the end of the financial year by yourself. There are lots of official rules and people who know what to do that can help you. If you know where to find good, clear advice, it will make a real difference. It will help you do things right so you do not feel as stressed.
You can get help from government websites and from people who give professional advice. It does not matter if you just have a small question or if you need more help for the whole financial year. It is a good idea to reach out for help. We will show you the best places to go if you need some support.
Inland Revenue (IRD) Resources and Tools
The Inland Revenue Department (IRD) is the top place to go for clear rules about your tax obligations in New Zealand. Their website has plenty of information, tools, and help to guide you on taxes, so it is the best spot to check when you need answers. This is where you should start if you want to know the facts about inland revenue.
You will see guides on the IRD website for things like how to do your tax return and about types of tax such as GST and FBT. The IRD also has a secure online website called myIR, which lets you do things like manage your tax, send in returns, and talk with them online.

A registered tax agent or an accountant will look at your situation and give you tips just for you. They help you get the most out of your tax, while making sure you do everything right.
These experts can help you with many things. They help with bookkeeping, your financial statements, planning for tax, and filing your return.
