Income to a trust with two grantors after one dies
My parents had a revocable living trust. My father died in February and his former employer paid a large, taxable death benefit to the trust (which got its own EIN in order to receive the payment). Mom was still alive when that payment was received and was still a grantor on the trust. She died a few months later, at which point the trust became irrevocable. Is that benefit taxable to mom and dad on their final tax return since it was received to the trust while mom was still alive, or is it taxable to the trust? If the latter, can it be passed through to the beneficiaries of the trust?
