Calculating your tax

Do you have to pay income tax?
Whether your not-for-profit organisation has to pay income tax will depend on whether it is exempt from income tax. Only certain types of not-for-profit organisations are exempt. Many are taxable and may need to lodge income tax returns and pay income tax.
