How to Start a Business in New Zealand: Tax and Accounting Tips

Starting a business in New Zealand is relatively straightforward, but getting your tax and accounting setup right from day one will save you money, stress, and compliance issues later. Here are the key steps and tips:

1. Choose the Right Business Structure

  • Sole Trader: Simple and low-cost to set up. You and the business are legally the same, and you’re taxed on profits at personal rates.

  • Company (Limited Liability): A separate legal entity. Offers limited liability, more credibility with clients, and potential tax advantages.

  • Partnership / Trust: Suitable in specific circumstances, often for family or asset protection.

Tip: Many start as sole traders but later transition to a company for better tax efficiency and liability protection.

2. Register with Inland Revenue (IRD)

  • Get an IRD number for your business or company.

  • Register for GST if you expect turnover of more than $60,000 per year (voluntary registration is possible below this threshold).

  • Set up myIR access to manage tax returns and payments.

3. Understand Your Tax Obligations

  • Income Tax: Sole traders pay personal income tax on profits; companies pay 28% flat rate on profits (plus tax on shareholder salaries/dividends).

  • Provisional Tax: Once your residual income tax exceeds $5,000, you may need to pay tax in instalments during the year instead of at year-end.

  • GST (Goods and Services Tax): Charged at 15% on most goods and services; requires regular GST returns (monthly, two-monthly, or six-monthly).

  • ACC Levies: Compulsory insurance for self-employed and business owners, calculated on your income.

4. Set Up Accounting and Record-Keeping Early

  • Open a separate business bank account to keep personal and business finances apart.

  • Use accounting software (e.g., Xero) to manage invoices, receipts, and bank reconciliations.

  • Keep records for at least 7 years (IRD requirement).

  • Consider using a chartered accountant to set up your chart of accounts correctly.

5. Claim All Legitimate Business Expenses

  • Home office deductions if you work from home.

  • Vehicle expenses for business use.

  • Software, training, and subscriptions related to your trade.

  • Professional fees (accountants, lawyers, advisors).

Proper expense tracking reduces your taxable profit and your tax bill.

6. Plan for Cashflow and Tax Payments

  • Put aside a portion of income (20–30%) into a separate tax savings account.

  • Use IRD’s calculators or get advice on how much provisional tax to set aside.

  • Avoid surprises, late tax payments incur use-of-money interest (UOMI) and penalties.

7. Get Professional Advice Early

  • An accountant can help with:

    • Choosing the best structure for your business.

    • Registering for GST and PAYE correctly.

    • Setting up efficient systems in Xero or other software.

    • Planning for tax so you’re not caught out at year-end.
