Why Tax Isn’t an Expense – And Why That Matters
When running a business in New Zealand, it’s easy to fall into the trap of treating tax like just another business cost. But here’s the truth: GST, provisional tax, and income tax are not business expenses. They are financial obligations owed to Inland Revenue — and they require careful planning.
Failing to treat tax as a separate obligation often results in stress, cashflow issues, and large bills at the end of the year. That’s why understanding how to manage and prepare for tax is critical for business success.
What Is Provisional Tax?
Provisional tax is not a separate type of tax — it’s a system for paying your income tax in instalments throughout the year. If your end-of-year tax bill is over $2,500, you’ll likely need to start paying provisional tax for the next year.
Here’s how it works:
-
You estimate your tax bill based on your expected profit.
-
You pay in two or three instalments during the year.
-
These payments are then deducted from your final tax bill.
By spreading your income tax payments, provisional tax helps reduce the burden of a large one-off payment.
Understanding GST for NZ Businesses
If you’re GST-registered, you must collect GST (typically 15%) on your sales and pay GST on your expenses. The difference is what you owe to Inland Revenue.
📌 Remember:
GST is not your money — it belongs to the government. It’s your responsibility to collect and pass it on. That’s why it’s vital to put aside the GST portion of each sale, rather than spending it.
Income Tax & Drawings: What to Watch Out For
Income tax in a business structure like a sole trader or partnership is based on the net profit (income minus deductible expenses). However, for business owners, drawings — the money you take from the business for personal use — don’t reduce your tax bill.
It’s a common misconception that you only pay tax on what you take out. In reality, you pay tax on the profit, regardless of how much you personally draw.
What About Fringe Benefit Tax (FBT)?
If you offer perks to employees — like a company car, meal allowances, or entertainment — you might be liable for Fringe Benefit Tax. This is an additional tax on non-cash benefits.
💡 Tip:
Talk to your accountant regularly to review your FBT exposure and ensure you’re meeting your obligations without overpaying.
Set Up a Tax Holding Account (Seriously, Do It)
To avoid a nasty surprise come tax time, we strongly recommend creating a dedicated tax holding bank account. Here’s how to use it:
-
Transfer GST, provisional tax, and estimated income tax into it monthly.
-
Treat these amounts like “untouchable” funds.
-
When tax bills arrive, you’ll already have the money saved.
This simple strategy transforms tax from a panic-inducing event into a routine financial habit.
Final Thoughts: Stay Proactive with Your Accountant
Tax planning isn’t a once-a-year conversation. Your accountant can help you:
-
Estimate your provisional tax accurately
-
Optimise your expense claims
-
Stay on top of GST
-
Ensure you’re FBT compliant
✅ Key takeaway: Treat tax like a responsibility, not an afterthought. Set aside what’s needed, stay informed, and get ahead of the curve.
