Keeping records and claiming business expenses

Published on March 14, 2015

You hear it time and time again - keeping good business records pays dividends. There are legal reasons for keeping accurate records, as well as good business reasons, such as supporting the expenses you've claimed against your business income.

With the end of the tax year fast approaching, you might be starting to prepare your tax returns. If you've kept good records it'll be a breeze, whether you do the return yourself or get a tax agent to do it for you. If you haven't made a good job of record keeping it might be difficult putting all the paperwork together. You could also miss out on claiming some expenses.

When's the best time to get a good record-keeping habit? Now is good.

From the beginning of a new tax year, start filing your statements, invoices, GST returns and interest statements. You can use a manual filing system or computer-based program, as long as you keep it in order and up to date, and you can retrieve information easily when you want to. Records you need to keep include:

  •     receipts or invoices for all claims
  •     interest and dividend statements
  •     a record of rental income and expenses
  •     purchase and sale agreements (for disposal of investment assets).

What you can claim

You can claim most of your business expenses, for example:

  •     running costs of using a vehicle for work purposes, transport costs and business travel
  •     rent paid on business premises
  •     depreciation on items such as your computer and office furniture
  •     part of any household expenses if you use your home for your business, eg, mortgage interest, telephone and electricity
  •     interest on borrowing money for the business
  •     some insurance premiums
  •     work-related journals and magazines
  •     membership of professional associations
  •     work-related mobile phone, stationery and uniforms
  •     tax agent's fees.
