What must appear on an NZ Taxable Supply Information (GST invoice) for packages, deposits, and commissions?

Since Inland Revenue modernised GST invoicing into Taxable Supply Information (TSI), every GST-registered NZ coach, personal trainer, real estate salesperson, event planner, or creative freelancer must provide the following details on sales over $200 (incl. GST):

• Below $200 (incl. GST): Your business name, 8- or 9-digit IRD/GST number, date of supply, description of services, and the total amount paid with a statement that it includes 15% GST.
• Above $200 (and over $1,000 incl. GST): Must also show the recipient’s name and contact details (address, email, or phone) and either the GST-exclusive amount + 15% GST amount + GST-inclusive total, or the inclusive total with a clear statement that 15% GST (3/23 of the total) is included.
• Under $60,000 Turnover (Not GST-Registered): Never display a GST line or claim that GST is included; issue a standard “Invoice” for the flat dollar amount.

How do Provisional Tax (28 Aug, 15 Jan, 7 May), ACC Earners’ Levy, and Student Loan stack on NZ sole trader profit?

Once your Residual Income Tax (RIT — the tax left owing on your IR3 after any WT withholding credits) exceeds $5,000 in a tax year, Inland Revenue automatically places you into Provisional Tax for the following year (paid in 3 instalments on 28 August, 15 January, and 7 May under the Standard +5% Uplift, Estimation, or AIM methods):

• The Full NZ Sole Trader Stack on $85,000 Net Profit: Alongside progressive NZ income tax (10.5% to $15,600; 17.5% to $53,500; 30% to $78,100; 33% to $180,000), self-employed Kiwis also pay ACC Work & Earners’ Levies (~1.60%–2.20% billed by ACC after you file your IR3) and, if applicable, 12% compulsory Student Loan repayments on every dollar of net profit above $24,128.
• That means at $85,000 net profit with a Student Loan, every $100 in unrecorded $1.17/km driving or gym/studio receipts costs you $46.75 (33% income tax + 12% Student Loan + 1.75% ACC) plus $13.04 in GST!

How do 15% GST and Schedular Payment (WT) withholding work for NZ real estate agents, coaches, and creatives?

Under the Goods and Services Tax Act 1985 and Schedule 4 of the Income Tax Act 2007, NZ solo service professionals must manage two separate tax streams:

NZ Service Profession	Schedular Payment (WT / IR330C) Rule	15% GST ($60,000 Rolling 12-Month Threshold)
Commissioned Real Estate Salespeople	Agencies deduct 20% standard Withholding Tax (WT) from your commission (unless you hold a 0% or tailored IR23BS certificate). Ensure you hand in IR330C so the 45% no-declaration penalty rate does not apply!	Crucial Trap: Even though the agency deducts 20% WT for income tax, you are still a self-employed contractor for GST! Once your gross commissions cross $60,000/year, you must register for 15% GST and file GST 101A returns.
Personal Trainers, Coaches & Event Planners	Direct B2C/B2B coaching packages, PT sessions, and event coordination fees are generally invoiced gross (0% WT), unless contracted under a specific Schedule 4 entertainment/media or labour-only category.	Compulsory at $60,000 turnover. On the Payments Basis (used by most solo businesses), you only pay 15% GST (3/23 of GST-inclusive price) to IRD when the client actually pays your invoice.
Freelance Video Producers, Photographers & Entertainers	Corporate/agency production contracts for television, video, photography, or promotional appearances often fall under Schedule 4 Part F (20% WT) unless exempted; direct client invoices are paid gross.	Mandatory at $60,000. Exported digital services/media billed to overseas clients (e.g. Australia, US, UK) are zero-rated (0% GST) under s11A GST Act 1985, while you still claim 100% of NZ GST input credits!

What IRD business expenses can NZ coaches, personal trainers, real estate agents, and event planners claim in 2026?

If you are GST-registered, remember IRD’s golden rule: your IR3 / IR10 income tax return uses GST-exclusive figures (because the 15% GST portion is already claimed back on your GST 101A return). If you are not GST-registered, you claim the full GST-inclusive receipt amount on your IR3:

Expense Category	2026 IRD Deduction Rule & Statutory Rate	Common IRD Audit Traps to Avoid
Motor Vehicle ($1.17/km Tier 1 Rate)	Claim $1.17/km (petrol, diesel, hybrid, or EV) for the first 14,000 km of annual vehicle travel based on a 90-day IRD vehicle logbook (valid for 3 years if business use stays within ±20%), or deduct your actual business percentage of fuel, RUC, WoF, rego, insurance & depreciation.	Claiming 100% of a personal SUV or hatchback without a 90-day logbook, or claiming private home-to-gym travel unless your home is a recognised workplace/office.
Home Office ($55.80/m² + Fixed Costs)	Under IRD’s square-metre option, claim $55.80 per square metre of your dedicated workspace for utilities (power, gas, internet) plus your floor-area percentage (e.g. 12%) of mortgage interest, council rates, house insurance, or rent.	Claiming the principal repayment portion of your home mortgage (only mortgage interest is deductible on IR3!).
Equipment Under $1,000 (Low-Value Assets)	Under IRD’s low-value asset threshold, any business asset costing $1,000 or less (ex-GST if GST-registered) — kettlebells, resistance bands, lockboxes, tripods, tablets, microphones — is 100% deductible immediately in the year of purchase. Assets over $1,000 (MacBooks, cinema cameras) are depreciated using IRD depreciation rates.	Expensing a $3,500 MacBook or camera body in full in year 1 instead of applying the IRD diminishing-value (50% for computers) depreciation rate.
Client Coffee, Meals & Entertainment (Subpart DD)	Under Subpart DD of the Income Tax Act 2007, taking a client out for coffee, lunch, or dinner, or providing food/drink at corporate events, is restricted to a 50% tax deduction (and you can only claim 50% of the GST input credit).	Claiming 100% of client café meetings or daily personal lunches while working locally.

Should a self-employed NZ personal trainer or contractor skip claiming expenses when applying for a mortgage?

A frequent question on New Zealand finance forums is whether sole traders should artificially skip claiming legitimate IR3 deductions to inflate taxable income for a bank mortgage application:

• Why Skipping Deductions Backfires: Not claiming $15,000 in legitimate vehicle, studio rent, and home-office expenses costs you $4,500 to $5,850 in permanent, non-refundable IRD income tax, ACC levies, and Student Loan repayments (30%–39% tax + 1.75% ACC + 12% Student Loan).
• How NZ Banks & Brokers Actually Assess Sole Traders: Mortgage lenders look at your gross invoiced revenue, cashflow consistency, add-backs (such as home-office apportionment and vehicle depreciation), and IR10 / IR3B profit & loss statements. Using clean, sequentially numbered invoices and an itemised ledger in the Keel Income Proof & Mortgage Dossier Edition gives your mortgage adviser verifiable gross and net figures without throwing thousands of dollars away in unnecessary tax.

Frequently asked questions

Do NZ real estate agents have to register for 15% GST if the agency already deducts 20% withholding tax? Yes. In New Zealand, the 20% Schedular Payment Withholding Tax (WT) deducted by a real estate agency only covers income tax (IR3). For GST purposes, a commissioned real estate salesperson is carrying on an independent taxable activity: as soon as your gross commission turnover exceeds (or is expected to exceed) $60,000 in any 12-month period, you must register for 15% GST and file GST 101A returns.

If I am GST-registered in New Zealand, do I include GST in my IR3 income tax expenses? No. When you are registered for 15% GST, you report both your gross business income and your deductible business expenses excluding GST on your IR3 (IR3B or IR10), because the 15% GST (3/23 of the total) is accounted for separately on your GST 101A returns. If you are not GST-registered (turnover under $60,000), you claim the full GST-inclusive cost of your business receipts on your IR3.

Can an NZ personal trainer deduct gym clothing, shoes, and personal gym memberships? Under IRD’s nexus and private limitation rules (s DA 1 and s DA 2 Income Tax Act 2007), conventional activewear, shorts, leggings, running shoes, and personal gym memberships are treated as private expenses and are not deductible, even if worn while coaching clients. You can deduct commercial gym floor rent / studio hire fees, PT liability insurance, REPs registration, fitness equipment (≤$1,000 instant write-off), and protective/branded uniform garments prominently displaying your business logo.

What is the 2026 IRD square-metre rate for home office claims in New Zealand? IRD’s standard square-metre utility rate is $55.80 per square metre of your dedicated home workspace (covering electricity, gas, and home internet/phone utilities), plus you can still claim your floor-area business percentage (e.g. 10%–15%) of your fixed home occupancy costs (mortgage interest, council rates, house insurance, or rent).

How long must NZ sole traders and contractors keep tax invoices and receipts for IRD? Under Section 22 of the Tax Administration Act 1994, New Zealand sole traders, freelancers, and independent contractors must retain all Taxable Supply Information (invoices), expense receipts, bank statements, and 90-day vehicle logbooks for at least 7 years from the end of the income year (1 April – 31 March) to which they relate. Digital photo scans stored in an app or iCloud are fully compliant.
