If you operate your business as a trust, and you incur a tax loss, you cannot distribute the loss to the trust’s beneficiaries. Instead, losses must be quarantined in the trust to be carried forward by the trust indefinitely until offset against future net income. It is possible to use those losses as deductions against income in the trust in future income years if the trust satisfies certain tests relating to ownership or control of the trust. If the trust terminates before the losses can be offset against income, they are lost.
