Figure out how much tax you owe

You need to pay tax on everything your business earned, minus your expenses. It’s easy to work out how much that will be with this Inland Revenue tax calculator. There are four main types of business – sole trader, partnership, company or non-profit organisation – find out which you are and how much tax you need to pay. This figure won’t include the ACC tax levy you’ll need to pay, you can calculate that here.

What expenses can you claim?

Anything you pay for to help run your business can be claimed back as an expense. Xero makes it easy to keep track of all the little bits of paper by taking photos of expense receipts directly with the app.

Expenses can include:

  • purchases of supplies or inventory to make a product or to sell to a customer
  • rent on the office or space you work in
  • payment of salaries or wages to people working for your business

If you work from home, work out the percentage of the costs of the house you can claim back. Claims on capital expenses – things like vehicles, computers or land – are calculated by depreciation. Find out how much you can claim on these purchases this year with this depreciation guide.

Make sure you don't claim personal expenses as business expenses, it’s against the law.

Write it off

If you can’t recover money from outstanding accounts, write them off before 31 March to reduce your tax.

Check your stock to make sure you’re not paying tax on anything that is damaged or can’t be sold. You can write this stock off. Plus, if you have less than $10,000 worth of stock (excluding GST) at the end of financial year, you don’t need to include it for tax purposes.

If you’ve made donations to a charity organisation, you can claim your tax credit for donations.
