GST on second-hand goods

Let’s say, for example, you’re running a landscaping business and want to purchase a new piece of equipment. You may consider buying them second-hand because they’re generally cheaper than new ones. However, the question arises 'how do I deal with the GST on second-hand goods?'
We quite often get asked if you can claim back GST on second-hand goods for your business from someone that isn’t GST registered. For example, you might buy a piece of business equipment for your cleaning business on TradeMe and the seller isn’t going to provide a nice GST invoice for your records. Or you bought a second-hand printer for your business.
Well, the good news is you can claim back the GST amount on your purchase even if the seller is not GST-registered.
Calculating GST on second-hand goods
You take the total price paid (you have to actually have paid for it before you claim) and divide by 23 and multiply by 3 to get the GST portion. Alternatively, just pay through your business bank account and treat as a GST purchase in your software and that should do the trick.
For example, Anna bought a second-hand printer for $100. The GST portion on this second-hand printer is $100*3/23= $13.04.
If you're purchasing from someone who is not GST-registered you probably won't get an invoice. However, in order to claim the GST on your purchase you still need to keep records as required by the IRD.

Keeping records of Second-hand goods
If you don’t have a GST invoice, you still need to record the following information about the item you've purchased:
- Name and address of the supplier
- Date of the purchase
- Description of the goods
- Quantity of goods
- Price paid
- Goods are situated in New Zealand
Exception
The only exception to this general rule is if you’re buying from someone associated to you. For example, if you buy a car from your brother and he’s not GST registered, then you can only claim the lowest of:
- Purchase price
- Current market value, or
- GST component (if any) of the original cost of the item to the supplier
This is to prevent any tax shenanigans between mates or family!

Other FAQs on GST
1. What is GST?
Goods and Services Tax (GST) is 15% added on top of the goods/services you buy and sell. If you're GST registered, you can claim back the GST portion on the purchases of goods or services you use for taxable business activities.
2. Where can I find my GST number?
For sole traders, your GST number is the same as your IRD number. For companies and partnerships, the GST number is the same as your partnership or company IRD number.
3. What are zero-rated supplies?
Simply put, a GST rate of 0% is applied for zero-rated supplies. Zero-rated supplies are not the same as supplies that are exempt from GST (no GST is charged). Find out more on how GST works for special transactions in this article.
4. When is my GST return due?
In New Zealand, the GST filing frequency is monthly, bi-monthly, or six-monthly. The frequency will typically depend on how large your business is. For example, businesses with sales under $500,000 during any 12-month period can file six-monthly GST returns. View the table on the IRD website for info on eligibility for different filing frequencies.
