Year-End Tax Planning Wellington is an important part of preparing your business for the end of the New Zealand financial year on 31 March 2027. Reviewing your income, expenses, GST, provisional tax, payroll records and business assets before the year closes can help you understand your financial position and prepare for upcoming tax obligations.

For Wellington business owners, the end of the financial year is an opportunity to check financial records, identify outstanding compliance matters, review cash flow and plan for the next financial year. Leaving these tasks until the last minute can make it harder to identify errors, organise supporting documents and prepare for tax payments.

1. What Is Year-End Tax Planning?

Year-end tax planning is the process of reviewing your business’s financial position before the end of the income year and preparing for the tax and accounting requirements that follow.

For most New Zealand businesses with a standard balance date, the financial year runs from 1 April to 31 March. The 2026–2027 income year therefore ends on 31 March 2027.

Year-end tax planning is not simply about reducing your tax bill. It is about understanding your taxable income, checking that financial records are accurate, reviewing legitimate deductions and ensuring that your business is prepared for upcoming obligations.

For businesses in Wellington, working with an experienced accounting team can help make this process more organised. DFK Orb360 O’Halloran provides tax advisory, accounting and financial reporting support to help businesses review their financial position and plan ahead.

2. Review Your Business Income and Expenses

One of the first steps in preparing for the financial year-end is reviewing your business income and expenses. Accurate records help your accountant understand your business’s financial performance and identify information that may need further attention.

What should you review?

• Business income: Check that sales, service revenue and other business income have been recorded correctly.
• Outstanding invoices: Review unpaid customer invoices and identify overdue accounts.
• Operating expenses: Check rent, utilities, insurance, software subscriptions, professional fees and other business costs.
• Business purchases: Ensure purchases have been recorded in the correct accounting period.
• Personal and business transactions: Identify any personal expenses incorrectly recorded as business expenses.
• Supporting documents: Check that invoices, receipts and other relevant records are available.

Remember that not every payment made before 31 March automatically qualifies as a tax deduction in that income year. The nature of the expense, when it is incurred and the applicable tax rules all matter.

DFK Orb360 O’Halloran can help Wellington businesses review their financial records, prepare financial statements and identify areas requiring further accounting or tax attention.

3. Check Your GST and PAYE Obligations

GST and PAYE are important compliance areas for businesses operating in New Zealand. Before the financial year ends, review your GST returns, payroll records and outstanding tax payments to identify any discrepancies.

GST review checklist

• Check that GST returns have been filed for all required periods.
• Reconcile GST figures with your accounting records.
• Review taxable sales and business purchases.
• Check that GST treatment has been applied correctly.
• Identify any outstanding GST payments or refunds.
• Keep relevant taxable supply information and supporting records.

PAYE and payroll review checklist

• Check payroll records against employee payments.
• Review PAYE deductions and payday filing records.
• Check KiwiSaver deductions and employer contributions where applicable.
• Review employee leave and other payroll balances.
• Identify outstanding employer tax obligations.

Businesses should also check that their payroll and GST information is consistent with their accounting records. Errors or missing information can make year-end reporting more difficult.

DFK Orb360 O’Halloran provides accounting and tax compliance support, including assistance with GST, payroll-related accounting and financial reporting for businesses across Wellington.

4. Review Your Provisional Tax Position

Provisional tax is a way of paying income tax throughout the year rather than waiting until the end of the income year. It generally applies when a taxpayer’s residual income tax from the previous year exceeds the relevant Inland Revenue threshold.

For businesses, provisional tax is an important cash flow consideration. If your business income or profitability has changed significantly, your provisional tax position may need to be reviewed.

What should businesses check?

• Review provisional tax instalments already paid.
• Compare your current financial performance with previous years.
• Assess whether your estimated taxable income has changed.
• Check whether your current provisional tax calculation method remains appropriate.
• Identify any potential shortfall or overpayment.
• Plan for upcoming income tax payments.

Common provisional tax calculation methods

The most suitable method depends on your circumstances, income pattern and eligibility. Changing your estimate without a reasonable basis can create additional tax costs, so seek professional advice before making adjustments.

DFK Orb360 O’Halloran can help businesses review their provisional tax position, understand upcoming payments and consider how tax obligations affect cash flow.

5. Review Business Assets and Depreciation

Business assets such as computers, machinery, vehicles, furniture and equipment may have tax depreciation implications. Reviewing your asset register before the financial year closes helps ensure that asset information is accurate and properly recorded.

Inland Revenue generally allows businesses to claim depreciation deductions on eligible capital assets used in their business. The applicable depreciation treatment depends on the asset, its use and the relevant tax rules.

What should you check?

• Review your business asset register.
• Identify assets purchased, sold or disposed of during the year.
• Check that asset descriptions and purchase dates are accurate.
• Review the applicable depreciation method and rate.
• Check whether any assets are used partly for private purposes.
• Retain invoices and other supporting purchase documents.

It is important to distinguish between ordinary operating expenses and capital expenditure. Buying an asset does not automatically mean that its full purchase price can be deducted immediately. Depreciation and any applicable special tax provisions need to be considered.

DFK Orb360 O’Halloran can assist businesses with financial reporting, asset records and tax advisory considerations relating to business assets.

6. Organise Your Financial Records and Reconcile Accounts

Accurate bookkeeping is essential for preparing financial statements and completing tax returns. Before 31 March, review your accounting software and supporting records to ensure that your financial information is complete.

Year-end bookkeeping checklist

• Reconcile business bank accounts.
• Reconcile business credit cards and loan accounts.
• Review accounts receivable and outstanding customer balances.
• Review accounts payable and unpaid supplier invoices.
• Check inventory records where applicable.
• Review loan balances and business finance arrangements.
• Check shareholder current accounts where relevant.
• Organise invoices, receipts and supporting financial documents.

New Zealand businesses generally need to keep tax records for at least seven years. These records may include invoices, receipts, bank statements, accounting records and information about business income, expenses, assets and liabilities.

Maintaining organised records throughout the year can reduce the time needed to prepare annual accounts and resolve discrepancies.

DFK Orb360 O’Halloran offers accounting, reporting and cloud accounting support to help businesses maintain reliable financial information.

7. Prepare a Cash Flow Forecast for the New Financial Year

Year-end tax planning should also consider what happens after 31 March. A business may be profitable on paper but still experience cash flow pressure if customer payments are delayed or tax obligations fall due at the same time as other major expenses.

Preparing a cash flow forecast can help you understand expected money coming into and leaving your business over the coming months.

What should your forecast include?

• Expected sales and customer payments.
• Supplier payments and operating expenses.
• Staff wages and payroll-related obligations.
• GST and provisional tax payments.
• Loan repayments and financing costs.
• Planned business purchases and investments.
• Expected seasonal changes in revenue.

Reviewing cash flow regularly can help business owners identify potential funding gaps before they become urgent. It can also support decisions about hiring, investment, expansion and managing operating costs.

DFK Orb360 O’Halloran provides accounting and business advisory support to help businesses assess financial performance, understand cash flow and plan for future requirements.

Important New Zealand Tax Dates to Understand

New Zealand businesses should distinguish between the financial year-end, tax return filing deadlines and tax payment dates. These dates are not necessarily the same.

Important: The dates above are general guidance, not a complete payment calendar. Your actual filing and payment deadlines may differ depending on your balance date, tax agent status, GST filing frequency and provisional tax method. Check your myIR account or confirm the relevant dates with your tax adviser.

Common Year-End Tax Planning Mistakes Businesses Should Avoid

Some year-end problems arise because financial records and tax obligations are not reviewed regularly. Avoiding the following mistakes can help make the process more manageable.

1. Leaving bookkeeping until the last minute

Waiting until after 31 March to reconcile transactions can make it harder to identify missing invoices, incorrect entries and outstanding balances.

2. Forgetting outstanding tax obligations

Unpaid GST, PAYE or provisional tax can affect cash flow and may lead to penalties or interest if obligations are not met.

3. Claiming expenses without adequate support

Business deductions must meet the relevant tax requirements. Keep supporting documents and ensure expenses are genuinely connected to the business.

4. Ignoring business asset records

Failing to record asset purchases, disposals or changes in business use can affect depreciation calculations and financial reporting.

5. Not planning for tax payments

Businesses that do not set aside money for tax can face cash flow pressure when payment dates arrive.

6. Treating tax planning as a once-a-year activity

Tax planning is more effective when financial performance and upcoming obligations are reviewed throughout the year, rather than only in March.
