For many New Zealand business owners, tax time can feel like a disruption, just when you’re focused on growing your business, the next GST or provisional tax payment is due. It’s not that you’re unorganised; it’s that juggling day-to-day operations and financial obligations often leaves little room for planning.
And when income varies month to month, or invoices are still waiting to be paid, setting money aside for tax can feel like just another thing on a very long list.
Tax doesn’t have to feel like a surprise or a setback. With a few simple, consistent habits, you can stay ahead of your tax commitments without it impacting your cash flow or causing unnecessary stress.
In this guide, we’ll walk through a straightforward system to help you set aside tax money with ease, clarity, and confidence so tax time becomes just another step in your rhythm.
Understand What You Owe and When
Getting clarity on your tax obligations is the first step to avoiding stress.
Before you can confidently set money aside, you need to know what you’re responsible for. As an SME in New Zealand, your tax obligations may include:
- Goods and Services Tax (GST): If your business earns over $60,000 annually, you’re required to register for GST and file returns either monthly, two-monthly, or six-monthly. The standard GST rate is 15% of taxable sales.
- Income Tax (including Provisional Tax): Sole traders, partnerships, and companies pay income tax on their net profit. If your total tax liability exceeds $5,000 at the end of the year, you’re likely to fall into the provisional tax regime, which means you’ll need to make multiple payments throughout the year (typically three instalments, depending on your method).
- ACC Levies: Most business owners also pay ACC Workplace Cover levies, which are based on industry risk and income levels. These often arrive as a separate invoice after the tax year ends.
Understanding these obligations and when they’re due is essential for setting the right savings strategy. You don’t need to get every number exact upfront, but having a clear estimate gives you a strong foundation.
Build a Simple and Automated Tax Saving System
Remove the guesswork by creating a process that works in the background.
Setting money aside doesn’t need to be complex or time-consuming. A few key systems can make this process smooth and stress-free.
- Use a Separate Tax Savings Account: Open a dedicated account with your bank for tax savings only. Every time money comes into your business, transfer a portion into this account immediately. This reduces the risk of accidentally spending what you owe.
- Allocate a Percentage of Every Payment: A reliable rule of thumb is to transfer the following from each payment you receive:
- 15% for GST (if registered)
- 20%–30% for income tax (depending on your tax bracket or company structure)
- 3%–5% for ACC and other obligations
- Automate Your Transfers: Set up recurring automatic payments weekly or fortnightly to your tax savings account. This makes it easier to stay consistent, even during busy periods.
- Review Your System Each Quarter: Your business may grow or slow down during the year. Revisiting your percentages regularly helps you stay on track with your savings and avoid under- or over-saving.
- Use Accounting Software or Forecasting Tools: Accounting software can help you track income and GST obligations in real time. These tools also give you estimated income tax liabilities based on your profits.
By building this system into your business rhythm, you’re no longer reacting to tax deadlines; you’re proactively managing them.
Align With the Cash Flow of Your Business
Planning tax payments in a way that fits your cash cycle is key to long-term sustainability.
Tax planning should reflect how money moves through your business. Here’s how to make it work for you:
- Think Monthly, Not Quarterly: Even if your payments are due every quarter, treat tax savings like a monthly bill. This spreads the burden and makes payments feel more manageable.
- Plan for Seasonality: If your business has seasonal highs and lows, adjust your savings strategy accordingly. Save more during peak months, and reduce during quieter periods, just make sure the average across the year meets your estimated obligations.
- Track Provisional Tax Obligations Closely: Inland Revenue (IRD) expects provisional tax payments based on prior year earnings (or estimated current year income). Using the “Standard” or “Estimation” method may influence how much you need to pay and when. It’s best to consult with your accountant if your income fluctuates or if you’re unsure which method applies.
- Reconcile Regularly and Keep Good Records: Ensure your bookkeeping is kept up to date. Timely and accurate record-keeping helps you spot potential shortfalls or excesses in your tax savings and avoid unexpected liabilities.
By aligning your tax strategy with your actual cash flow and income rhythm, you stay in control, even when business is unpredictable.
Make Tax Work With You, Not Against You
Running a business already comes with enough moving parts; your tax obligations shouldn’t add more uncertainty to the mix. When you’ve got a clear plan for setting money aside, tax payments become something you’re prepared for, not something you’re chasing down.
A system that works with your cash flow, not against it, gives you more than just peace of mind; it gives you headspace to focus on the bigger picture. You know what’s coming, you’ve planned for it, and you can move forward with confidence.
