A business tax advisor does more than prepare your annual accounts. They look at your whole financial picture, including your business structure, how you pay yourself, what you own and how, where your income flows, and they find legal ways to reduce your tax liability over time.
This is NOT tax avoidance. Everything covered in this article is fully compliant with Inland Revenue. Good accounting and tax services are about making deliberate decisions within the rules, not working around them.
If you're searching for a tax consultant near me or a tax advisor near me, what you're really looking for is someone who's in your corner year-round, not just at the end of March.
This is one of the most powerful tools in business tax advisory, and one of the most underused.
In New Zealand, companies pay a flat 28% tax rate on profits. Personal income tax, on the other hand, scales up to 33% for income between $78,101 and $180,000, and 39% on anything above that.
That gap is significant. If your business is profitable and you're drawing a high personal salary, you could be paying 33 to 39 cents in the dollar on a portion of your income when 28 cents was the alternative.
The strategy isn't to stop paying yourself. It's to be deliberate about how much salary you draw, how much profit stays in the company, and when and how retained earnings eventually come back to you. Getting this balance right requires genuine tax advice in New Zealand because there are IRD rules around what's reasonable, and getting it wrong creates problems. Getting it right creates consistent savings year after year.
How you take money out of your company has a direct impact on how much tax you pay. Most business owners default to a salary and don't think much further, but there's a smarter way to approach this.
Salary is deductible to the company (reducing its taxable profit) and taxed as personal income in your hands via PAYE.
Dividends are paid from after-tax company profit. You get an imputation credit for the 28% company tax already paid, which offsets personal tax. If your personal tax rate sits below 28%, dividends can come to you with no further tax to pay.
The right mix depends on your personal income, your business profit, whether you have a spouse or partner involved in the business, and whether retained earnings are building up. A personal tax accountant might get you someone who can file the returns, but a business tax advisor will help you model the actual after-tax outcomes of different combinations.
One common mistake: business owners pay themselves entirely through salary at a rate that pushes them into the 33% or 39% band, when a combination of a moderate salary and dividends would have been more tax-efficient overall. Because the company has already paid 28% tax on profits before they're distributed, dividends carry an imputation credit that offsets your personal tax. If your marginal rate is 30% or 33%, the top-up is small (2% or 5%). If you're in the 39% band, you'll still pay the gap, but splitting income between salary and dividends, and potentially across a spouse, can keep more of the household income in lower brackets.
Working from home is normal for most business owners, and home office deductions are legitimate and valuable. But they're often either missed entirely or claimed incorrectly, both of which cost you money.
The general principle is that you can claim a portion of your home running costs as a business expense if you use part of your home to run your business. This includes mortgage interest or rent, rates, insurance, power, and internet.
The calculation is based on the proportion of your home that's used for business. IRD accepts a floor area method: divide the area of your dedicated workspace by the total floor area of the home to get the percentage you can claim.
For a business owner with $3,500 per month in mortgage interest, $400 in rates, $200 in insurance, and $300 in power and internet, even a modest 15% allocation adds up to meaningful tax savings every year.
A few things to get right:
The space should be genuinely used for business purposes. A room you occasionally use with a laptop on the couch is different from a dedicated office.
Keep records. IRD can ask you to substantiate the claim, so a floor plan or measurements and a summary of how the space is used is worth having on file.
If you own your home and your company pays you rent for the space, this is a different structure with different rules and requires advice before implementing.
Free tax advice NZ-style can point you in the right direction, but the detailed calculation and documentation is worth doing properly with a tax advisor to avoid issues down the line.
Vehicles are one of the biggest areas of tax leakage for small business owners. Many either claim too little (missing legitimate business use) or claim too much (which creates Fringe Benefit Tax exposure). Getting this right requires understanding how your vehicle is owned and used.
If the company owns the vehicle and you use it for business, the running costs are deductible to the company. If there's any private use, FBT applies, and this can be significant if not structured correctly.
If you personally own the vehicle and use it for business, you can claim a mileage rate (IRD publishes a standard rate per kilometre) or claim the actual business proportion of running costs.
The right structure depends on how much you drive, what the vehicle is worth, and how much of your use is genuinely business-related. For some business owners, a company vehicle with an FBT calculation works out better than claiming personal mileage. For others, the reverse is true. A business tax advisor can model both scenarios against your actual numbers.
Logging matters here, but the good news is you don’t need to do this in a hard copy logbook! Use an app like Drivers Note. IRD expects records of business travel, and without them your claim is on shaky ground regardless of how legitimate it is.
If you're a director-shareholder of a company, the salary you pay yourself is one of the most flexible tax levers available to you, if you understand how it works.
Your shareholder salary reduces the company's taxable profit, which reduces company tax. It then becomes personal income, taxed at your marginal rate. The goal is to find the optimal point where the total tax paid (company plus personal) is minimised, not to blindly push the number up or down.
This is where a lot of business owners overpay. A high shareholder salary that pushes personal income into the 33% or 39% bracket, when the company rate is 28%, is simply leaving money on the table.
There are also rules around shareholder salaries and ACC levies to consider. ACC is based on personal income, so a higher shareholder salary means higher ACC bills. This is worth factoring into the calculation.
Shareholder salary decisions also affect provisional tax, KiwiSaver obligations (if applicable), and the overall cash flow of the business. This is exactly why having a business tax advisory professional on your side is important. It’s so you can have consistent conversations when questions come up, instead of a reactive once-a-year conversation.
When income is recognised and when expenses are claimed can legally shift your tax position, sometimes by a meaningful amount.
In New Zealand, businesses with a 31 March balance date have flexibility around:
Prepaid expenses: Some expenses paid before balance date can be claimed in the current year rather than the next, bringing forward the deduction.
Deferred income: If a payment is received in advance for services not yet delivered, there may be grounds to treat it as income in the following year.
Accruals and provisions: Making sure all genuine liabilities are accrued at year end means the profit figure reflects reality, not just what's been invoiced or paid.
This isn't about manipulating the numbers. It's about making sure the timing of your tax matches the timing of your economic activity. Done properly, it smooths your provisional tax obligations and avoids the cash flow crunch that comes from paying tax on income that's already been spent.
Family trusts are a widely used structure in New Zealand, and for good reason. When used correctly, they can reduce tax by spreading income across beneficiaries at lower marginal rates, provide asset protection, and assist with intergenerational wealth transfer.
If a trust is a shareholder of your business, distributions from the trust can be made to beneficiaries who are in lower tax brackets, reducing the overall tax paid on that income.
This isn't a shortcut or a loophole. IRD has specific rules about how trusts operate and what constitutes legitimate income splitting versus artificial arrangements. The key is having a trust that's properly set up, actively governed, and used in a way that reflects genuine commercial and personal reality.
If you don't currently have a trust and your business is generating significant profit, this is worth discussing with a tax advisor. If you do have a trust and it hasn't been reviewed recently, it's worth checking that it's still being used in the most effective way.
The strategies above aren't a checklist to work through once. They're the ongoing conversation that a good business tax advisor has with you throughout the year.
The questions that should come up regularly:
This is different from what most accounting and tax services provide. It requires a proactive relationship, not a compliance-only one. If the last time your accountant talked to you about tax was when they sent your annual accounts, you're probably overpaying.
