The 31 March Deadline: An EOFY Checklist for NZ Business Owners

New Zealand essentially has two New Years. The first arrives in January with beach towels and melting ice cream. The second, far more consequential for your bank balance, falls on 31 March. This is the moment the Inland Revenue Department (IRD) draws a line under your year and begins calculating exactly how much of your progress belongs to the Crown.

For many business owners, March is a frantic scramble through glove boxes for crumpled receipts and late-night emails to an accountant who is already handling twenty other late-night emails. The most successful ones treat 31 March differently. Not as a deadline to survive, but as an annual diagnostic check on their most important asset: the business itself.

New Zealand is genuinely a nation built on small business. According to MBIE data, Small and Medium Enterprises (SMEs) comprise over 97 percent of all businesses and employ roughly 29 percent of the private-sector workforce.

If you are reading this in the final stretch before year-end, good. There is still time to act.

Your Accountant Is Not Your Saviour

A common and expensive misconception is the belief an accountant will simply \"fix\" a tax bill in May. By then, the ink is dry. An accountant is, at their core, a historian. They record what has already happened. To influence the outcome, it's best to ensure your financial affairs are in order before the clock hits midnight on 31 March.

GST, Records, and the Small Business Shoebox Problem

GST returns are filed separately from income tax, but the two are connected, of course. A clean set of records before 31 March makes both processes significantly faster and cheaper. If you are still hunting down receipts in batches every quarter, the problem is not March. It is the eleven months before it.

Accounting tools like Xero can automate the bulk of this work throughout the year, leaving March as a confirmation exercise rather than a forensic reconstruction. Xero, for instance, allows real-time collaboration with your accountant, connects to debtor management and payroll tools, and removes the possibility of a frantic email chain in the final fortnight before EOFY. If you are not using an integrated accounting system by now, the cost of not doing so is real. It shows up in your accounting fees, in time you cannot get back, and in the quality of decisions you make with incomplete information.

Chase the Slow Payers. Before They Chase You

Cash is oxygen. As March approaches, ensure all vendor invoices are paid so every expense lands in the correct period. More importantly, get onto your slow-paying clients now. Most businesses have at least one client who treats a 20-day invoice as a polite suggestion rather than a legal obligation. You know who they are. Call them in mid-March. Do not wait.

Your accountant will appreciate a clean aged-receivables report, your bank balance will look considerably healthier, and you will have avoided the indignity of asking someone to pay an invoice from October while simultaneously trying to close off a financial year.

A part of this is ensuring you're a good SME operator, by paying all your bills on time, too!

Payroll: The Area Most Business Owners Assume Is Fine (Until It Isn't)

PAYE, KiwiSaver deductions, employer student loan repayments, and employer superannuation contributions all need to be filed and paid correctly throughout the year. By 31 March, the question is whether you have been doing it right.

Payroll systems like iPayroll economically handle PAYE filing directly with the IRD, connect directly to Xero, calculate deductions automatically, and maintain a clean record year-round. Before close-off, confirm all March pay runs are finalised, any outstanding PAYE is filed and paid, and employee tax codes and KiwiSaver rates are current. You won't have to lift a finger at financial year end. Most payroll systems also handle staff leave, saving you another headache.

While reviewing payroll, check outstanding annual leave balances. High accrued leave is a liability on the books. Nudging staff to take a regular break is good for team morale, individual wellbeing, and quietly tidies up your financial statements for any lenders or buyers reviewing them later.

The Shareholder Current Account: The Number Most People Ignore

This is possibly the most misunderstood figure in New Zealand business accounting. If you have been using the company bank account for personal expenses throughout the year, you likely have a \"debit\" shareholder current account. In plain terms: the company has been giving you an interest-free loan.

The tax collector (IRD) takes a dim view of this. If the account is overdrawn at year-end, the company may be required to charge you interest at the applicable rate, which has not been particularly charitable recently. The goal is to get this to zero, or into credit, before 31 March.

A credit balance is a different matter entirely. It means the company owes you money, which gives you the flexibility to withdraw funds tax-free in future periods. It also demonstrates to any bank or prospective buyer reviewing your books that there is a clean, professional separation between personal spending and business finances. A business with a messy current account signals lifestyle hobby. One with a clean balance sheet signals professional enterprise. If you ever intend to sell, this distinction could cost or earn you a material amount of money.

The Low-Value Asset Threshold: A Rare Moment of IRD Generosity

The IRD does not distribute many gifts, so it is worth paying attention when they do. Assets costing $1,000 or less (excluding GST) can currently be fully deducted in the year of purchase rather than depreciated over multiple years.

If you have been eyeing a new monitor, some tools, or a coffee machine to maintain team morale through winter, buying these before 31 March can be cleaner for your tax position. The difference between buying on 30 March and 1 April is not about the item. It is about which tax year absorbs the cost.

Worked example: A $950 (excluding GST) office chair purchased on 29 March reduces this year's taxable profit by $950. At a 28 percent company tax rate, that is $266 back in your pocket when terminal tax is settled. Buy the same chair on 1 April and that saving shifts entirely into next year's return. The chair is identical. Which tax year absorbs the cost is not.

What Non-Tax Related Matters Should You Consider, At Least Annually?

The 31 March deadline is a useful forcing function for tax, but it is also the most natural point in the calendar to lift your head from the day-to-day and ask a broader question: is the business building you long-term wealth, or just keeping you busy?

The $50,000 Mandate: Invest Away From Yourself

According to Stats NZ data, property alone accounts for nearly half of all New Zealand household wealth, and that figure climbs further once business ownership is factored in. For most small business owners, those two asset classes are not just dominant, they are essentially everything.

Over time, this approach is quietly dangerous.

Warren Buffett once observed that it is only when the tide goes out you learn who has been swimming naked. Even if you operate in a recession-proof industry, the International Monetary Fund has consistently noted small, open economies like New Zealand are disproportionately exposed to external shocks, and we all know how vulnerable New Zealand is to natural disasters. If your house, your income, and your retirement savings are all anchored to the same local economy and a single business entity, one significant downturn or black swan event puts all three at risk simultaneously. In Warren Buffett's eyes, you are swimming naked.

A disciplined business owner should aim to peel off a portion of profits every year and deploy it into liquid, diversified global assets. For some SMEs a starting target of $50,000 annually is meaningful, while others might aim for $500,000 or more annually. The exact figure matters less than the habit.

The compounding benefits of doing this consistently are wider than most people initially appreciate.

• You build a liquid safety buffer that is structurally separate from the business, meaning a difficult year in your industry does not wipe out your personal financial position.
• You create a visible track record of profit being distributed, which lenders find genuinely attractive when assessing creditworthiness for mortgages or growth capital.
• You begin to demonstrate, on paper, an enterprise capable of generating surplus rather than simply recycling every dollar back into itself. This makes the business materially more appealing to a potential buyer one day.

The point is straightforward: your business should be a vehicle for your life, not the entirety of it. An alarming number of business owners who would never put their entire personal savings into a single stock have, in effect, done exactly that with their own company.

Risk Management: Two Things Worth Reviewing Before Year-End

Most New Zealand business owners remain on standard ACC cover, where compensation is calculated from prior-year earnings. If your income fluctuates year to year, this creates real uncertainty at the point of a claim. ACC CoverPlus Extra allows you to agree on a specific compensation figure upfront, regardless of what your most recent tax return shows. For variable-income owners, the certainty alone is worth a review conversation, consider the following example:

Mark owns a dairy farm worth $4.2 million and pays himself a shareholder salary of $65,000 in a good year and considerably less in a bad one. Under standard ACC cover, a four-month injury leaves him compensated on whatever last year's return showed. The farm still needs a relief milker. The mortgage does not pause.

Under ACC CoverPlus Extra, Mark agrees upfront to be covered for $120,000 per year. Sometimes, ACC CoverPlus Extra premiums can even be lower than typical ACC cover, but even if it costs more, the certainty is absolute.

Also note, there's a difference between ACC and income protection cover. ACC provides 80% of lost earnings strictly for accidental injuries, yet it offers no financial assistance if a medical illness or disability prevents you from working. Private income protection cover fills this gap by covering health-related absences, and unlike the mandatory government levy, these premiums are often tax-deductible.

The second is key person cover. If you are the engine of the business, what happens if that engine stops for six months? Key person insurance covers the cost of bringing in temporary management or maintaining fixed overheads during an extended absence.

For business owners with partners or co-shareholders, there is a related risk worth examining. If a business partner dies or becomes permanently unable to work, their share of the business may pass to their estate. You could find yourself in business with someone you have never met, who has no interest in the operation and every right to demand a say in it. A buy-sell agreement, supported by insurance set at the agreed value of each owner's interest, removes that risk cleanly. Each partner's cover is sized to allow the surviving owners to buy out the departing party's share at a pre-agreed price.

If either of these matters sounds like you, our team are standing by to assist. Book a free initial conversation.

KiwiSaver: Okay, But Don't Get Carried Away

If you are self-employed, there is a reasonable chance you are personally not a KiwiSaver Scheme member, as the government's annual contribution amounts to a couple of hundred dollars each year, so long as you're under the $180,000 income cap.

For self-employed owners who are in KiwiSaver, you are required to fund your own employer contribution out of business expenditure. If you choose to take it in the hand, or in a KiwiSaver account, that money is leaving the business either way. The question is whether you want it locked to a government scheme until you turn 65 or invested flexibly in an investment structure you control. For most business owners, the answer should be obvious.

Frequently Asked Questions: SME Year-End Edition

Do I need to do a physical stocktake?

If your trading stock is worth more than $5,000, yes. You must value it at cost or market selling value, whichever is lower. Below $5,000, you can generally use your opening stock value. If you are anywhere near the threshold, clarify with your accountant before 31 March rather than after.

Is business entertainment fully deductible?

Rarely. The standard position for client meals and entertainment is 50 percent deductible. The IRD's underlying logic is essentially that you would have eaten lunch regardless. End-of-year functions receive the same treatment. Budget accordingly.

What if I cannot pay my terminal tax on time?

Contact the IRD before the deadline, not after. They are considerably more reasonable than their reputation suggests when you approach them proactively. Using tax obligations as a short-term working capital loan, however, is one of the most expensive habits a business owner can develop. The interest and penalties accumulate quickly and serve no one except the IRD.

When should I tell my accountant that March is closed off?

As soon as you can after 31 March. The sooner the period is confirmed, the sooner your accountant can commence the financial statements. If your books are on a cloud-based system and have been reconciled throughout the year, this handover can happen in days rather than weeks.

What about provisional tax? Am I paying the right amount?

If your income has grown significantly this year, your provisional tax payments may be underfunded. Review this in early March with your accountant. The IRD charges use-of-money interest on underpaid provisional tax, and discovering a shortfall in May is considerably less useful than addressing it before year-end.

The Bottom Line: Your EOFY Small Business Checklist

The 31 March deadline is, at its best, an annual act of accountability. It forces you to look at the numbers as they are, not as you hope them to be. The business owners who take this window seriously, who clean up the accounts if needed, time their purchases deliberately, and begin directing surplus into genuinely diversified assets, build more resilient wealth than those who hand a shoebox to their accountant and hope for the best.

Your business is a vehicle. Make sure it is taking you somewhere.
