Changes to the Federal Tax Withholding Rate

Title: II, Voucher And Invoice Payments Manual
Chapter: 2, Travel and Transportation Payments, Section 1, Travel System (TRVL)
Bulletin: 01-1, Changes to the Federal Tax Withholding Rate
Date: August 2, 2001
To: TRVL Users

In accordance with the Economic Growth and Tax Relief Reconciliation Act of 2001 (H.R. 1836), the flat withholding rate for Federal income taxes withheld on supplemental wages paid after August 6, 2001, will decrease from 28 percent to 27.5 percent.

TRVL is affected by this decrease in the withholding tax rate because certain relocation travel expenses are considered supplemental wages and are subject to tax withholding (taxable). TRVL computes and withholds Federal, state, and FICA/HIT taxes from those travel vouchers that include taxable expenses. Therefore, relocation vouchers paid after August 6, 2001, will be subject to the new Federal withholding rate of 27.5 percent.
