Tax year
Name of trust (or decedent's estate)
Fiduciary's Name and Address

Enter the Name and title of fiduciary and the Telephone number (optional).
Enter the Number and street. (If a P.O. box, see instructions.) and the Room or suite no.
If the post office doesn't deliver mail to the street address and the fiduciary has a P.O. box, show the box number instead of the street address.

Line 1 Total amount of estimated taxes

Enter the Total amount of estimated taxes to be allocated to beneficiaries here and on Form 1041, Schedule G, Part II, line 11.
Enter the amount of estimated tax payments made by the trust or decedent's estate that the fiduciary elects to treat as a payment made by the beneficiaries. This amount is treated as if paid or credited to the beneficiaries on the last day of the tax year of the trust or decedent's estate. Be sure to include it on Form 1041, Schedule B, line 10.
You can't allocate to a beneficiary tax withheld from income, such as withholding from lottery or other gambling winnings, or from salary or pension payments reported on Form 1041. You must report this withholding on Form 1041, Schedule G, Part II, line 14.
Line 2 Allocation to beneficiaries

Line 2 Column (b)-Beneficiary's name and address. Group the beneficiaries to whom you are allocating estimated tax payments into two categories. First, list all the individual beneficiaries. Then, list all the other beneficiaries.
For each beneficiary, enter the appropriate taxpayer identification number (TIN). This is generally the social security number (SSN) for individuals or employer identification number (EIN) for all other entities.
Failure to enter a valid SSN or EIN may cause a delay in processing and could result in penalties being imposed on the beneficiary.
For those beneficiaries who file a joint return, you can assist the IRS in crediting the proper account by also providing the SSN, if known, of the beneficiary's spouse. However, this is an optional entry.
For each beneficiary, also report this amount in box 13 of Schedule K-1 (Form 1041), using code A.
For each listed beneficiary, divide the amount shown in column (d) by the amount shown on line 1 and enter the result as a percentage.
Lines 3 and 4 Totals

If you are allocating a payment of estimated taxes to more than 10 beneficiaries, list the additional beneficiaries on an attached sheet that follows the format of line 2. Enter on line 3 the total from the attached sheet(s).
3 Total from additional sheet(s).
Total amounts allocated. (Must equal line 1, above.)
