Does a trust have to pay Federal withholding tax when it pays distribution to beneficiaries?

The trust is in Kansas, and Kansas requires 2.5% of distributable income to be withheld from receiving beneficiaries for income tax purposes. Does the IRS require similar withholding of income when a trust makes distributions to US citizens? I've searched the internet and found that only distributions to foreigners must have income withheld for tax purposes. Thanks.
