Tax Return and Payment

if you're in business, you'll need to complete and send us an income tax return which is Form 11 within 4 months after each fiscal year, and attach your financial statements. 

For example if your fiscal year is July to June, your income tax returns should be due on the 31st October every year. If your fiscal year is January to December, your income tax return should be due on the 30th April every year. 

You are obliged to lodge your return and pay your tax on time unless you have been granted an extension to the time of lodgment and payment.
