It depends on the type of trust that you created.
Grantor trusts, where the grantor has control over the assets, generally require grantors to report all income from a trust on their own individual tax returns. Non-grantor trusts, on the other hand, work differently. Typically, the trust itself or its beneficiaries pay tax on taxable income.
Income kept in the trust is paid on a trust tax return using Form 1041. Income distributed to beneficiaries is reported to the beneficiaries by the trust using Form K-1 and then that form is used to prepare your individual tax return, Form 1040.
