When are Trusts supposed to submit a ITR12 tax return?

As far as I know, provisional tax payers should submit their tax returns end of January and companies end of February, of the following year of assessment. But when are trusts supposed to submit their tax returns if they are not registered provisional taxpayers?

The filing deadline for the 2015 Tax tax return for Trusts is 27 November 2015 (i.e the same as non-provisional individual taxpayers).

Thank you!

Only a pleasure!
