Which option provides the least tax burden?
The actual treatment for distribution and tax purposes is dependent upon the language in your trust.
The "least tax burden" will be dependent upon the beneficiary's federal and state income tax bracket and liability for the year of the distribution.
However, since trust income tax rates are highly compressed, it is typically better to make the distribution to the beneficiary rather than have the trust assume the tax liability.
