If you are registered for GST and it was payable in relation to your rental income, do not include it in the amounts you show as income in your tax return.
Similarly, if you are registered for GST and entitled to claim input tax credits for rental expenses, you do not include the input tax credits in the amounts of expenses you claim. If you are not registered for GST, or the rental income was from residential premises, you include any GST in the amounts of rental expenses you claim.
