Managing Multiple Trading Names
Juggling multiple brands, side-hustles, or business divisions? Learn why the IRD links GST to the "Legal Person" and how to stay compliant with one GST number.
The 10-Second Rule
GST registration is attached to the **Legal Entity** (the person or company), not the brand. You use **one GST number** for all your trading names and consolidate their total turnover into **one return**. Separate bank accounts are recommended, but one tax bill is mandatory.
The Brand Umbrella
1. Sole Traders: The Aggregation Rule
As a sole trader, you are the legal entity. This means the IRD does not care if you have ten different businesses; they see you as one person with one tax obligation.
- ✓ **Combined Turnover**: You must add income from ALL brands to see if you hit the $60k threshold.
- ✓ **Single Return**: You file one GST return per period, totaling all sales and expenses across all activities.
- ✓ **Tracking Categories**: Use software features like Xero "Tracking" to keep your brand P&Ls separate.
The Threshold Trap
You cannot avoid GST registration by splitting your income between multiple trading names. If Brand A earns $40k and Brand B earns $25k, your total turnover is **$65,000**. You must register for GST and charge it on sales for BOTH brands.
2. Company Branch Registration
Companies have a unique option under **Section 56 of the GST Act**. If a business division is distinct and has its own accounting system, it can apply for "Branch Registration."
Must have a separate location or carry out a distinct activity from the main company.
Must maintain its own independent accounting records and file its own GST returns.
3. Invoicing Requirements
When issuing invoices for different brands, the legal link must be clear to avoid customer confusion during their own IRD audits.
| Component | Requirement |
|---|---|
| Name | Legal name OR the trading name registered with IRD. |
| GST # | Must be the correct number for the umbrella entity. |
| Footer | Best practice: "Trading division of [Legal Entity Name]". |
