Online lodgement

Lodging online is the easiest and most convenient way to lodge. It’s is quick, secure, tailored to you. You can also view and revise your previously lodged statements.

If you lodge quarterly, and need a little extra time to lodge, you may receive an extra two weeks to lodge and pay.

So take time back and lodge your BAS online.

Remember, you still need to lodge your BAS by the due date, even if you can’t pay on time. Let us know as soon as you can if you don’t think you’ll be able to lodge or pay on time and we’ll work with you to find a solution.

Record keeping

Good record keeping is essential for anyone in business because it makes it easier to manage your cash flow, meet your tax obligations and understand how your business is doing. Records you need to keep:

  • Receipts and tax invoices for good and services you buy and sell
  • Employee wages and other costs to your business (including license fees and costs of utilities)
  • Bank statements

Good record keeping practices can help you get your refund faster if we need to check your claim. Some tips on good record keeping are:

  • Keep accurate records of all sales and purchases
  • Store your records electronically
  • Ensure your records contain enough information to calculate and support the amount on your BAS, and
  • Retain a copy of all tax invoices and other GST records for 5 years.
