## Why does every sole trader it consultant software developer ird ir3 depreciation gst invoice setup in NZ start with `0%` zero-rated exports & `IR265`?

Independent software engineers, DevOps/cloud architects, IT contractors, UX/UI designers, and digital marketers in Auckland, Wellington, Christchurch, Tauranga, and Queenstown file an annual **[Inland Revenue (`IRD`) Individual Income Tax Return (`IR3`)](https://www.ird.govt.nz/income-tax/income-tax-for-individuals/types-of-individual-income/self-employed)** alongside the **Financial Statements Summary (`IR10`)** for the NZ tax year (**1 April to 31 March**).

Three high-impact New Zealand tax rules give Kiwi tech contractors and digital freelancers a massive cash-flow advantage:

1. **`0%` Zero-Rated Overseas Tech & Consulting Exports (`GST Act 1985 s. 11A(1)(k)`):**
   - Mandatory NZ **`15%` GST registration (`Form GST101A`)** starts at **`NZ$60,000` turnover in any 12-month period**.
   - If you code, design, or consult from Auckland or Wellington for **overseas clients in the US, Australia, UK, or Singapore** (who are outside NZ when the services are performed), your invoices are **zero-rated at `0%` GST**—*not* exempt!
   - That means your overseas USD/AUD revenue counts toward the `NZ$60,000` GST threshold, you charge your overseas client **`0%` GST**, and **Inland Revenue pays you a direct `15%` cash GST refund** on every MacBook Pro, monitor, coworking membership, fibre internet bill, and accountant invoice you pay in New Zealand!
2. **`NZ$1,000` Low-Value Asset Write-Off + `IR265` `50% DV` Computer Rate + `20%` Investment Boost (from 22 May 2025):**
   - Any tool, monitor, mechanical keyboard, microphone, or peripheral costing **under `NZ$1,000` (ex-GST if GST-registered)** is written off **`100%` immediately in Year 1** (`s. EE 38 Income Tax Act 2007`).
   - Under **[IRD Schedule `IR265` (General Depreciation Rates)](/keel/nz-depreciation-rates/)**, laptops, desktop workstations, and tablets (`>= NZ$1,000`) have a `4-year` estimated useful life and depreciate at **`50% Diminishing Value (`DV`)` or `40% Straight Line (`SL`)`**—and under the **2025/26 `20%` Investment Boost** for new productive business assets acquired from **22 May 2025**, you deduct **`20%` upfront PLUS `50% DV` on the remaining `80%` = `60%` total Year-1 income tax deduction** (on top of your `100%` immediate `15%` GST refund)!
3. **Evaluability Hypothesis (`Hsee, 1996`) & Loss Aversion ($\lambda \approx 2.25$):** Every **`NZ$100` in unrecorded SaaS subscriptions, cloud hosting, home-office expenses, or ACC levies** costs a Kiwi IT contractor **`NZ$30.00 to NZ$39.00` in IRD income tax** (`30%` from `NZ$53,501–$78,100`, `33%` from `NZ$78,101–$180,000`, `39%` over `NZ$180,000`)—plus **`NZ$15.00` in unclaimed GST input credits**!

| **Monitors, mechanical keyboards, webcams, docks, routers & headsets (`< NZ$1,000` ex-GST per item)** | **Box 26** (*Other expenses — Low-value assets*) | **100% immediate write-off in Year 1** under the `NZ$1,000` low-value asset threshold (`s. EE 38`) |
| **Ergonomic office chair (`Herman Miller`) & standing desk (`>= NZ$1,000`)** | **Box 18** (*Depreciation*) | **`20% DV` or `13.5% SL`** (`IR265` *Office furniture/chairs*, 10-yr life) or `16% DV` (*Desks*, 12.5-yr life); **100% immediate write-off if `< NZ$1,000`** |

| **Business car travel (`NZ$1.17/km` Tier 1 rate for the first `14,000 km`), Wellington/Auckland client flights & coworking passes** | **Box 26** (*Vehicle & travel expenses*) | **`NZ$1.17/km` (IRD Tier 1 rate for petrol/hybrid, `NZ$1.08/km` EV)** up to `14,000` total km without fuel receipts (requires a 90-day logbook every 3 years) |
| **Professional Indemnity (`PI`) / Cyber Liability insurance, Chartered Accountant fee, Stripe/Wise FX fees** | **Box 20** (*Interest*) & **Box 26** (*Professional fees & insurance*) | **100% deductible** |

## What must appear on a New Zealand IT consultant or developer invoice (`Taxable Supply Information` & `Withholding Tax WT` rules)?

Since **1 April 2023**, Inland Revenue replaced traditional *"Tax Invoices"* with **Taxable Supply Information (`TSI`)**:

1. **For Invoices Over `NZ$1,000` (incl. GST) to NZ Clients:** Include your name/trading name, **8- or 9-digit IRD / GST number**, client name and address, date of invoice, itemized description of software/consulting sprints, and either the **pre-GST amount + `15% GST` + total** or the GST-inclusive total with a statement that **`"Total includes 15% GST of $X.XX"`**.
2. **For Overseas US / AU / UK Tech Clients (`0%` Zero-Rated):** Include your details, service dates, currency (`USD`, `AUD`, or `NZD` converted at the IRD/RBNZ mid-month or transaction-day exchange rate), and the line: **`"Zero-rated export of services — 0% NZ GST (Goods and Services Tax Act 1985, s. 11A(1)(k))"`**.
3. **Schedular Payments (`IR330C`) When Contracting Through an NZ Recruitment Agency:** If you contract via an NZ IT recruitment agency (like Robert Walters, Hays, or Absolute IT), they may deduct **Schedular Withholding Tax (`WT`, default `20%` for company/labour-hire or your elected rate on `Form IR330C`, min `10%`)**. Those `WT` deductions are **pre-paid income tax credits** that reduce your end-of-year `IR3` tax bill and can even remove you from **Provisional Tax** if they cover your residual income tax within `NZ$5,000`!

## How does ACC CoverPlus Extra (`CPX`) reduce levies and improve tax deductions for NZ tech contractors?

Because software engineering and IT consulting fall into a low-risk physical classification unit (`ANZSIC M700000` *Computer System Design and Related Services*), switching from standard **ACC CoverPlus** to **ACC CoverPlus Extra (`CPX`)** lets a high-earning NZ developer lock in an agreed level of weekly compensation while lowering their annual ACC invoice—and `100%` of the ACC Work/CPX business levy is deductible on `IR10 Box 26`.

## Worked example: How much IRD `IR3` tax & GST does a Wellington software developer save on `NZ$135,000`?

Suppose a Wellington full-stack developer bills **`NZ$95,000` (`0%` zero-rated to a San Francisco SaaS company)** and **`NZ$40,000` (`+ NZ$6,000` `15%` GST to a Wellington ministry)**:
- **Gross Self-Employed Income (`IR3` / `IR10 Box 2`, ex-GST):** **`NZ$135,000`**
- **Allowable `IR10` Deductions (`NZ$18,920` ex-GST) + `NZ$2,340` GST Input Credits:**
  - **New MacBook Pro M4 Max (`NZ$5,200` ex-GST) — `20%` Investment Boost (`NZ$1,040`) + `50% DV` on remaining `NZ$4,160` (`NZ$2,080`) = `60%` Year-1 Depreciation (`Box 18`):** `NZ$3,120` (+ **`NZ$780` immediate cash GST refund**!)
  - **Two 4K Monitors (`NZ$780` each ex-GST) + Keychron Keyboard (`NZ$260`) + Webcam (`NZ$220`) — `100%` Low-Value Asset Write-Off (`< NZ$1,000` each — `Box 26`):** `NZ$2,040`
  - **AWS, Cursor, GitHub Copilot, Linear, Figma, Wise FX Fees (`Box 26`):** `NZ$3,890`
  - **Home Coding Room (`12%` of home rent, power & insurance) + Fibre Broadband & Mobile (`Box 26`):** `NZ$5,620`
  - **ACC CoverPlus Extra Levy, PI Cyber Insurance & Accountant Fee (`Box 26`):** `NZ$3,180`
  - **Client Travel (`915 km @ NZ$1.17/km` — `Box 26`):** `NZ$1,070`
- **Taxable Net Profit (`IR10 Box 29`):** `NZ$135,000 - NZ$18,920 =` **`NZ$116,080`**
- **Total IRD Income Tax (`33%` bracket) + `15%` GST Saved:** **`NZ$8,583.60`** stays in your pocket!
