GST change-in-use calculator

Use this calculator to work out your change-in-use adjustments for goods or services bought or introduced into your taxable activity on or after 1 April 2011.

Note: You don’t need to adjust goods or services costing $5,000 or less.

This calculator can help you when:

  • you're completing a GST adjustments sheet or GST return
  • you're calculating change-in-use adjustments for goods or services
  • you know what your change-in-use percentage is (GST-inclusive value of the goods or services) and can work out the adjustment amount
  • you're a person who is not principally making supplies of financial services
  • the total value of your exempt supplies will be more than $90,000 or 5% of the total consideration for your taxable and exempt supplies for the period, and
  • you’re not using the adjustment periods that are equal to the number of years for the goods or services estimated useful life.

Note: This calculator doesn't incorporate the wash-up adjustment for change of use to either 100% taxable or non-taxable.

To get started, you'll need to know:

  • your balance date
  • the GST-inclusive cost of the goods or services
  • the percentage of the goods or services business use
  • the date you bought the goods or services, or introduced them into your taxable activity
  • the details if you sell or dispose of the goods or services.
