# Taxable Supply Information NZ GST Rules (2026–27): IRD $200 & $1,000 Tiers & Supply Correction Information

**Short answer: Under Sections 19E to 19N of the Goods and Services Tax Act 1985, Taxable Supply Information NZ GST rules replaced rigid "Tax Invoice" formatting with three data-based GST tiers: NZ$200 or less (supplier name, date, description, and total paid), over NZ$200 to NZ$1,000 (adds the supplier's 8/9-digit GST number and 15% GST indication), and over NZ$1,000 (adds buyer identity details and itemised GST). Changes to billed amounts require Supply Correction Information (credit/debit notes).**

> **⚡ Instant New Zealand GST (`15%`), NZBN & Taxable Supply Information Toolkit ($NZD):** Create a compliant NZ invoice with automatic 15% GST (`× 3 ÷ 23` extraction), 8/9-digit IRD GST number, and 13-digit NZBN in the **[Free NZ GST Invoice Generator](/keel/invoice-generator/)**, click **🔗 Embed / CSV Template** for a clean spreadsheet, save your first 5 records in the **[iCloud Web Workspace (5 Free Saves)](/keel/workspace/)**, explore the **[AU/NZ Tradies & Sole Trader App Store Edition](/keel/cpp/australia-nz-sole-traders/)**, or **[Download Keel Free on the App Store (`$0/mo` Core)](https://apps.apple.com/us/app/keel-invoice-maker-receipts/id6786659713?ppid=8470921a-830e-47a3-abf5-bf0b1cce24ac&pt=127772795&ct=blog_fatura_nz-ird-taxable-supply-info&mt=8)** (`au-nz-tradies`).

Since Inland Revenue modernised New Zealand's GST record-keeping framework under the **Goods and Services Tax Act 1985 (Sections 19E–19N)**, Kiwi sole traders, tradies, and independent contractors no longer have to print the exact words *"Tax Invoice"* or *"Credit Note"* at the top of a single piece of paper for a 15% GST claim to be legal.

Instead, **[Inland Revenue (IRD) Taxable Supply Information (TSI)](https://www.ird.govt.nz/gst/tax-invoices-for-gst/how-tax-invoices-for-gst-work)** and **[Supply Correction Information (SCI)](https://www.ird.govt.nz/gst/tax-invoices-for-gst/credit-and-debit-notes-for-gst)** focus on whether your digital invoice, trade docket, contract, or receipt records the **mandatory statutory data fields** for each dollar tier (**NZ$200 or less**, **over NZ$200 to NZ$1,000**, and **over NZ$1,000**)—and whether you issue them within the **statutory 28-day / 20th-of-the-following-month deadline**.

Below is the complete **2026–27** statutory guide to **Taxable Supply Information NZ GST rules**, **Supply Correction Information** (credit and debit notes), **Buyer-Created Taxable Supply Information (`BCTSI`)**, and how to protect your **Box 12 GST input tax deductions** during an IRD review. For related Kiwi guides, see **[NZBN invoice and docket book rules](/keel/nz-nzbn-invoice-and-docket-book-rules-ird/)**, **[how to calculate 15% GST in NZ](/keel/nz-how-to-calculate-gst/)**, and **[NZ IRD 7-year record-keeping rules](/keel/nz-ird-7-year-record-keeping-sole-trader/)**.

## What are the 3 tiers under Taxable Supply Information NZ GST rules (NZ$200 and NZ$1,000 thresholds)?

Under **Section 19K of the Goods and Services Tax Act 1985**, the data fields required to substantiate a **15% GST** supply (and for a GST-registered buyer to claim an input tax deduction in **Box 12** of their GST return) scale across three GST-inclusive value tiers:

| Statutory Data Field (`GST Act 1985 s 19K`) | **Tier 1: `NZ$200` or Less (Incl. GST)** | **Tier 2: Over `NZ$200` up to `NZ$1,000` (Incl. GST)** | **Tier 3: Over `NZ$1,000` (Incl. GST)** |
|---|:---:|:---:|:---:|
| **1. Supplier's legal or trading name** | **Required** | **Required** | **Required** |
| **2. Date of the invoice / date of supply** | **Required** | **Required** | **Required** |
| **3. Description of the goods or services supplied** | **Required** | **Required** | **Required** *(with quantities or volume of goods/services)* |
| **4. Total amount paid / consideration for the supply** | **Required** | **Required** | **Required** |
| **5. Supplier's 8- or 9-digit IRD / GST number** (`123-456-789`) | Not required | **Required** | **Required** |
| **6. Clear indication of 15% GST charged** | Not required | **Required** *(either show pre-GST subtotal + 15% GST + total, OR show GST-inclusive total with a statement that it includes 15% GST)* | **Required** *(must show the exact 15% GST amount or pre-GST + GST + total breakdown)* |
| **7. Recipient's (buyer's) name PLUS at least 1 recipient identifier** *(physical address, email, phone, trading name, URL, or **[13-digit NZBN](/keel/nz-nzbn-invoice-and-docket-book-rules-ird/)**)* | Not required | Not required | **Required** *(when selling to another GST-registered business)* |

### Can you still title your PDF "Tax Invoice" in New Zealand?
Yes. In fact, Inland Revenue explicitly confirms that existing **Tax Invoice** templates that include the Tier 3 fields above automatically satisfy **Taxable Supply Information (TSI)** across all three dollar brackets. Using a single clean **[NZ Tax Invoice template](/keel/nz-invoice-template/)** that always prints your trading name, **8/9-digit GST number**, **13-digit NZBN**, buyer's name/email/address, itemised quantities, net subtotal, **15% GST (`3/23` of gross)**, and GST-inclusive total guarantees compliance whether the job is **NZ$150** or **NZ$15,000**.

## What are the statutory timeframes for issuing Taxable Supply Information (28 days vs 20th of the following month)?

Under **Section 19L of the Goods and Services Tax Act 1985**, a GST-registered supplier in New Zealand must provide Taxable Supply Information to another GST-registered person within strict statutory deadlines:

1. **Supplies Over `NZ$200` to Another GST-Registered Business (Automatic Duty):**
   - When you make a taxable supply over **NZ$200 (including GST)** to a customer who is registered for GST, you **do not wait for them to ask**. You must provide Taxable Supply Information **within 28 days of the time of supply**—or, if you prefer a standard monthly billing cycle, **by the 20th of the month following the month in which the time of supply occurred** (matching standard Kiwi *"20th of the following month"* trade terms), or any alternative date agreed in writing between the supplier and buyer.
2. **Supplies of `NZ$200 or Less` (or where the buyer requests TSI):**
   - If a GST-registered customer requests Taxable Supply Information from you, you must provide it **within 28 days of receiving the request** (or by an agreed alternative date).

## What is Supply Correction Information (SCI — Credit and Debit Notes) under NZ GST rules?

When an already-issued GST invoice needs to be adjusted—for example, because materials were returned to the merchant, an agreed variation reduced the contract price, a discount was granted after billing, or 15% GST was miscalculated—**Section 19N of the GST Act 1985** requires the supplier to issue **Supply Correction Information (`SCI`)** (historically called a **Credit Note** or **Debit Note**).

To be legally valid for adjusting your **Box 9 (Output tax adjustments)** or **Box 13 (Input tax credit adjustments)** on your IRD GST return, **Supply Correction Information** must contain **all 4 mandatory items**:

| Mandatory SCI Field (`GST Act 1985 s 19N`) | What Must Appear on Your Credit Note / Debit Note / Variation Adjustment | Worked Example (`NZ$575.00` Credit on a `NZ$3,450.00` Job) |
|---|---|---|
| **1. Supplier's Name & GST Number** | Supplier's legal or trading name and **8- or 9-digit IRD GST number** (`123-456-789`) | `Auckland Electrical Contracting — GST: 123-456-789` |
| **2. Date of the Correction** | The calendar date the Supply Correction Information (credit or debit note) is issued | `Issued: 14 November 2026` |
| **3. Reference to the Original Supply (TSI)** | Information identifying the original Taxable Supply Information being corrected (such as the **original invoice number and date**, or the date and description of the original supply) | `Ref: Corrects Invoice #INV-2026-042 dated 28 October 2026 (Unused switchboard hardware returned)` |
| **4. The Exact Correction to the Consideration & GST** | The difference between the original GST-inclusive amount and the corrected amount, showing the **15% GST adjustment** (`× 3 ÷ 23`) | `Credit Subtotal: -NZ$500.00 | 15% GST Adjustment: -NZ$75.00 | Total Credit: -NZ$575.00 (Revised Invoice Total: NZ$2,875.00)` |

*Key Audit Rule:* Once you have accounted for a GST invoice in a filed GST return, you **must not** delete or overwrite the original invoice in your records. Instead, issue a sequential **Credit Note / Supply Correction Information** document and include the `NZ$75.00` GST adjustment in the GST return period in which the correction occurred.

## What is Buyer-Created Taxable Supply Information (BCTSI) for Kiwi Subcontractors?

Previously, if a principal contractor, dairy co-operative, forestry company, or scrap-metal buyer wanted to generate **"Buyer-Created Tax Invoices"** on behalf of its subcontractors, they had to apply to Inland Revenue in advance for formal approval.

Under the modernised **Taxable Supply Information NZ GST rules**, prior IRD approval is **no longer required** for **Buyer-Created Taxable Supply Information (`BCTSI`)**, provided **both** the GST-registered buyer and the GST-registered seller agree in writing (in a subcontract or trade agreement) that:
1. **Only the buyer** will issue the Taxable Supply Information for those supplies;
2. **The seller (subcontractor) will not** issue a duplicate invoice containing TSI for the same supply; and
3. Both parties retain a copy of the agreement and the BCTSI for **7 tax years**.

## Worked $NZD Examples across the 3 IRD Taxable Supply Information Tiers

Here is how the **15% GST calculation** (`Net × 0.15 = GST`, or `Gross × 3 ÷ 23 = GST`) and the required TSI fields work across all three New Zealand GST thresholds in **2026–27**:

| Scenario & Tier | Pre-GST Amount ($NZD) | 15% GST Component (`3/23` of Gross) | Total GST-Inclusive Price ($NZD) | Minimum IRD TSI Compliance Requirement |
|---|---:|---:|---:|---|
| **Tier 1: Hardware Store Fixings Docket (`<= NZ$200`)** | `NZ$160.00` | `NZ$24.00` | **`NZ$184.00`** | Supplier name, date, item description, and `NZ$184.00` total paid (keep photo of thermal docket for Box 12 claim) |
| **Tier 2: Residential Call-Out & Repair (`NZ$200.01–NZ$1,000`)** | `NZ$600.00` | `NZ$90.00` | **`NZ$690.00`** | Tier 1 fields **plus** Supplier's **8/9-digit GST number** and statement/breakdown showing **15% GST (`NZ$90.00`)** |
| **Tier 3: Commercial Subcontract Progress Claim (`> NZ$1,000`)** | `NZ$4,000.00` | `NZ$600.00` | **`NZ$4,600.00`** | Tier 2 fields **plus** **Buyer's name + 1 Buyer Identifier** (e.g., Buyer's **[13-digit NZBN](/keel/nz-nzbn-invoice-and-docket-book-rules-ird/)**, address, or email) and itemised quantities + separate `NZ$600.00` GST line |

## How do you store Taxable Supply Information and trade dockets for IRD's 7-year audit window?

Under **Section 75 of the Goods and Services Tax Act 1985** and **Section 22 of the Tax Administration Act 1994**, New Zealand sole traders and contractors must retain all Taxable Supply Information and Supply Correction Information (both issued client invoices and incoming supplier dockets over **NZ$200**) in English or te reo Māori for **7 years** after the end of the taxable period to which they relate. Because thermal receipts from Bunnings, Mitre 10, PlaceMakers, and fuel stations fade rapidly in a ute cab, photographing every docket into **[Keel](https://apps.apple.com/us/app/keel-invoice-maker-receipts/id6786659713?ppid=8470921a-830e-47a3-abf5-bf0b1cce24ac&pt=127772795&ct=blog_fatura_nz-ird-taxable-supply-info&mt=8)** under the job ensures your **Box 12 GST claims** and **[IR3B / IR10 sole trader deductions](/keel/nz-ir3b-and-ir10-sole-trader-schedule-guide/)** remain 100% readable for all 7 years.

## Frequently asked questions

**Did Taxable Supply Information replace Tax Invoices in New Zealand?**

Yes. Under Sections 19E to 19N of the **Goods and Services Tax Act 1985**, the term **Taxable Supply Information (TSI)** replaced the older statutory requirement to hold a single document titled *"Tax Invoice"*. However, Inland Revenue confirms that you **do not** need to stop using the heading *"Tax Invoice"*—any existing invoice template that displays the required TSI data fields for its dollar tier (**NZ$200 or less**, **over NZ$200 to NZ$1,000**, or **over NZ$1,000**) is 100% compliant.

**What is the threshold where I must keep Taxable Supply Information to claim GST in New Zealand?**

Previously, GST-registered businesses did not need a tax invoice for purchases of **NZ$50 or less**. Under the current **Taxable Supply Information NZ GST rules**, for supplies of **NZ$200 or less (including GST)**, you still need a basic record of the purchase (such as a store receipt or docket showing the supplier's name, the date, a description of the goods/services, and the total amount paid), while for any purchase **over NZ$200 (including GST)** you must hold full Tier 2 or Tier 3 Taxable Supply Information showing the supplier's **8- or 9-digit GST number** before claiming the 15% GST in **Box 12**.

**What happens if I am not registered for GST in New Zealand (under NZ$60,000 turnover)?**

If your annual turnover is under the **[NZ$60,000 GST registration threshold](/keel/nz-register-for-gst/)** and you are not registered for GST, you **must not** charge 15% GST, display a GST number, or issue Taxable Supply Information. Instead, issue a standard commercial invoice (ideally displaying your **[13-digit NZBN](/keel/nz-nzbn-invoice-and-docket-book-rules-ird/)**) with the clear statement *"Not GST registered — no GST charged"*.

**How many days do I have to provide Taxable Supply Information to a GST-registered buyer in NZ?**

Under Section 19L of the Goods and Services Tax Act 1985, for any taxable supply **over NZ$200 (including GST)** made to another GST-registered person, you must provide Taxable Supply Information **within 28 days of the time of supply** (or by the **20th of the month following the month of supply**, or an alternative date agreed by both parties). For supplies of **NZ$200 or less**, you must provide TSI **within 28 days** if the GST-registered buyer requests it.

**What must be included on Supply Correction Information (a GST credit note or debit note) in New Zealand?**

Under Section 19N of the GST Act 1985, when an invoiced amount changes after Taxable Supply Information has been issued, your **Supply Correction Information (credit note or debit note)** must show four details: **(1)** the supplier's name and 8/9-digit GST number, **(2)** the date the correction is issued, **(3)** a clear reference to the original invoice or supply being corrected, and **(4)** the exact correction to the consideration and the **15% GST adjustment** (`× 3 ÷ 23`).
