"Do I need to file a seperate 1041?
"
You can most likely use an optional method of filing that does not involve filing a 1041. If you gave payers of income (e.g., brokerage firms, banks) the TIN of the trust, you can file 1099s to report the income/gross proceeds paid to
the trust showing the trust as the payer and you as the payee.

Alternatively, you could essentially close your account (link below) and use your SSN since the grantor trust is a disregarded entity for federal income tax purposes. In that event, payers of income would issue tax reporting statements with your SSN and you would simply report the income/proceeds on your individual income tax return.

The foregoing notwithstanding, you should consider ongoing tax (and legal) advice from professionals who are familiar with estate planning/asset protection and income taxation of estates and trusts.
