The fiduciary, or an authorized representative, must sign Form 1041. If there are joint fiduciaries, only one is required to sign the return.
A financial institution that submitted estimated tax payments for trusts for which it is the trustee must enter its EIN in the space provided for the EIN of the fiduciary. Do not enter the EIN of the trust. For this purpose, a financial institution is one that maintains a Treasury Tax and Loan (TT&L) account. If you are an attorney or other individual functioning in a fiduciary capacity, leave this space blank. Do not enter your individual social security number (SSN).
If you, as fiduciary, fill in Form 1041, leave the Paid Preparer space blank. If someone prepares this return and does not charge you, that person should not sign the return.
