How to record self-employed income in New Zealand

Keep a record of what your business earns, who paid you and the documents that explain each payment. Save the payment evidence as well as the invoice, so you can follow a job from the work you billed to the money you received.

What Inland Revenue expects#

Keep invoices, bank statements and sales records alongside your business purchases. Inland Revenue accepts both paper and electronic records, provided they let you work out your income and expenses, check your accounts and calculate GST when registered; see Inland Revenue — Records of income and expenses.

A simple record for each payment#

Start with the document you already have: an invoice you sent, a customer's remittance advice or a platform's payout statement. Beside it, keep:

• the customer or payer and a useful reference;
• the invoice date and payment date, when they differ;
• the amount and currency;
• any tax shown and any fee held back;
• the bank entry or other evidence of payment.

This is a working checklist: its purpose is to make a payment understandable later. For a contractor with several jobs, a reference such as the site or project name is more useful than a folder called “income”.

Keep the payment and its costs connected#

When a customer pays through a platform, look at the breakdown before treating the deposit as the whole story. Keep the earnings, fee and payout distinguishable. Our platform statement guide walks through that check.

How long to keep the records#

Keep records of cash and electronic sales and purchases for seven years. Income, expenses, assets and liabilities are all part of the record trail. See Inland Revenue's record guidance and our country retention guide for the details.
