Interim Final Rule Calculates User Fees for Estate Tax Closing Letter (T.D. 10031; NPRM REG-107459-24)

The IRS issued interim final regulations on user fees for the issuance of IRS Letter 627, also referred to as an estate tax closing letter. The text of the interim final regulations also serves as the text of proposed regulations. These regulations reduce the amount of the user fee imposed to $56.

Background

In 2021, the Treasury and Service established a $67 user fee for issuing said estate tax closing letter. This figure was based on a 2019 cost model.

In 2023, the IRS conducted a biennial review on the same issue and determined the cost to be $56. The IRS calculates the overhead rate annually based on cost elements underlying the statement of net cost included in the IRS Annual Financial Statements, which are audited by the Government Accountability Office.

Current Rate

For this fee review, the fiscal year (FY) 2023 overhead rate, based on FY 2022 costs, 62.50 percent was used. The IRS determined that processing requests for estate tax closing letters required 9,250 staff hours annually. The average salary and benefits for both IR paybands conducting quality assurance reviews was multiplied by that IR payband’s percentage of processing time to arrive at the $95,460 total cost per FTE.

The Service stated that the $56 fee was not substantial enough to have a significant economic impact on any entities. This guidance does not include any federal mandate that may result in expenditures by state, local, or tribal governments, or by the private sector in excess of that threshold.
