Commercial Property GST Guide

Compulsory Zero-Rating (CZR), claiming GST on fit-outs, and commercial lease rules. Master the GST mechanics of large-scale property transactions.

The 10-Second Rule

Commercial property transactions involve large sums, and getting the GST wrong can mean a massive unexpected tax bill. The rules are heavily regulated by the IRD to prevent "phoenix schemes" and double dipping, primarily through **Compulsory Zero-Rating (CZR)**.

1. Compulsory Zero-Rating (CZR)

If a GST-registered person sells land or property to another GST-registered person who intends to use it for a taxable activity, the GST must be charged at 0%.

✓ Vendor pays $0 GST to the IRD.
✓ Purchaser claims $0 GST input tax.

Mandatory Rule Warning:

This is mandatory, not optional. If you charge 15% by mistake, the IRD will deny the purchaser's input tax claim but still demand the 15% from the vendor!

When Does CZR Apply?

🏢

1. Vendor is Registered

The seller must be GST registered.

🤝

2. Purchaser is Registered

The buyer is (or will be) GST registered.

📈

3. Taxable Activity

Buyer will use land for commercial purposes.

🚫

4. Not a Private Home

Not intended as principal place of residence.

2. Commercial Fit-outs and Input Tax

When you buy a commercial building under CZR, the transaction was Zero-Rated, so you claim nothing upfront for the building itself.

However, commercial fit-outs (carpets, specialized lighting, partitions) are treated differently.

Example A: The Retail Tenant

A retailer leases an empty shell building. They spend $80,000 on custom shelving, flooring, and lighting. Because they are paying for their own fit-out for their taxable activity, they can claim the full $10,434 input tax deduction in their next GST return.

3. Commercial Lease Rules

Unlike residential rent (which is exempt), rent on commercial property is a fully taxable supply.

✓ Landlord: Must charge 15% GST on rent and Opex (Operating Expenses).
✓ Tenant: Can claim 15% GST back as long as they are registered.

Example B: Lease Inducements ("Golden Hello")

If a landlord pays a tenant a $20,000 lump sum to sign a 5-year lease, the tenant must treat this as a taxable supply of services to the landlord. The tenant pays GST on that receipt, and the landlord can claim it back as a business expense.

4. Selling a Tenanted Property (Going Concern)

If you sell a commercial building that already has a tenant in place, it is often sold as a "Going Concern".

This means the sale is Zero-Rated (0%), provided both parties agree in writing and are GST registered. This is highly beneficial because the purchaser doesn't have to secure additional financing to cover a massive 15% GST component during the settlement process.

Frequently Asked Questions

When does Compulsory Zero-Rating (CZR) apply?

CZR applies when a GST-registered vendor sells land to a GST-registered purchaser who intends to use the land for making taxable supplies and does not intend to use it as their principal place of residence.

Can I claim GST on a commercial building fit-out?

Yes, if you lease a building and pay for your own fit-out, you can claim 15% GST on those costs immediately. If you bought the building under CZR, you claim nothing upfront for the structure itself.

Are lease inducements taxable?

Yes, if a landlord pays a tenant a lump sum to enter a commercial lease, the tenant must pay GST on that receipt (it is considered taxable income). The landlord can claim it back as a business expense.
