31.3402(g)-1—Supplemental wage payments.
(a) In general and withholding on supplemental wages in excess of $1,000,000—
(1) Determination of supplemental wages and regular wages—
An employee's remuneration may consist of regular wages and supplemental wages. Supplemental wages are all wages paid by an employer that are not regular wages. Supplemental wages include wage payments made without regard to an employee's payroll period, but also may include payments made for a payroll period. Examples of wage payments that are included in supplemental wages include reported tips (except as provided in paragraph (a)(1)(v) of this section), overtime pay (except as provided in paragraph (a)(1)(iv) of this section), bonuses, back pay, commissions, wages paid under reimbursement or other expense allowance arrangements, nonqualified deferred compensation includible in wages, wages paid as noncash fringe benefits, sick pay paid by a third party as an agent of the employer, amounts that are includible in gross income under section 409A, income recognized on the exercise of a nonstatutory stock option, wages from imputed income for health coverage for a non-dependent, and wage income recognized on the lapse of a restriction on restricted property transferred from an employer to an employee. Amounts that are described as supplemental wages in this definition are supplemental wages regardless of whether the employer has paid the employee any regular wages during either the calendar year of the payment or any prior calendar year. Thus, for example, if the only wages that an employer has ever paid an employee are payments of noncash fringe benefits and income recognized on the exercise of a nonstatutory stock option, such payments are classified as supplemental wages.
(ii) Regular wages.
As distinguished from supplemental wages, regular wages are amounts that are paid at a regular hourly, daily, or similar periodic rate (and not an overtime rate) for the current payroll period or at a predetermined fixed determinable amount for the current payroll period. Thus, among other things, wages that vary from payroll period to payroll period (such as commissions, reported tips, bonuses, or overtime pay) are not regular wages, except that an employer may treat tips as regular wages under paragraph (a)(1)(v) of this section and an employer may treat overtime pay as regular wages under paragraph (a)(1)(iv) of this section.
(iii) Amounts that are not wages subject to income tax withholding.
If an amount of remuneration is not wages subject to income tax withholding, it is neither regular wages nor supplemental wages. Thus, for example, income from the disqualifying dispositions of shares of stock acquired pursuant to the exercise of statutory stock options, as described in section 421(b), is not included in regular wages or supplemental wages.
(iv) Optional treatment of overtime pay as regular wages.
Employers may treat overtime pay as regular wages rather than supplemental wages. For this purpose, overtime pay is defined as any pay required to be paid pursuant to federal (Fair Labor Standards Act), state, or local governmental laws at a rate higher than the normal wage rate of the employee because the employee has worked hours in excess of the number of hours deemed to constitute a normal work week or work day.
(v) Optional treatment of tips as regular wages.
Employers may treat tips as regular wages rather than supplemental wages. For this purpose, tips are defined as including all tips which are reported to the employer pursuant to section 6053.
(vi) Amount to be withheld.
The calculation of the amount of the income tax withholding with respect to supplemental wage payments is provided for under paragraph (a)(2) through (a)(7) of this section.
(2) Mandatory flat rate withholding.
If a supplemental wage payment, when added to all supplemental wage payments previously made by one employer (as defined in paragraph (a)(3) of this section) to an employee during the calendar year, exceeds $1,000,000, the rate used in determining the amount of withholding on the excess (including any excess which is a portion of a supplemental wage payment) shall be equal to the highest rate of tax applicable under section 1 for such taxable years beginning in such calendar year. This flat rate shall be applied without regard to whether income tax has been withheld from the employee's regular wages, without allowance for the number of withholding allowances claimed by the employee on Form W-4, “Employee's Withholding Allowance Certificate,” without regard to whether the employee has claimed exempt status on Form W-4, without regard to whether the employee has requested additional withholding on Form W-4, and without regard to the withholding method used by the employer. Withholding under this paragraph (a)(2) is mandatory flat rate withholding.
(3) Certain persons treated as one employer—
(i) Persons under common control.
For purposes of paragraph (a)(2) of this section, all persons treated as a single employer under subsection (a) or (b) of section 52 shall be treated as one employer.
(ii) Agents.
For purposes of paragraph (a)(2) of this section, any payment made to an employee by a third party acting as an agent for the employer (regardless of whether such person shall have been designated as an agent pursuant to section 3504) shall be considered as made by the employer except as provided in paragraph (a)(4)(iii) of this section.
(4) Treatment of certain items in determining applicability of mandatory flat rate withholding—
(i) Optional treatment of compensation not subject to income tax withholding.
For purposes of paragraph (a)(2) of this section, employers may determine whether an employee has received $1,000,000 of supplemental wages during a calendar year by including in supplemental wages amounts includible in income but not subject to withholding that are reported as wages, tips, other compensation on Form W-2.
(ii) Allocation of salary reduction deferrals.
In allocating salary reduction deferral amounts excludable from wages for purposes of determining whether the employer has paid $1,000,000 of supplemental wages under paragraph (a)(2) of this section, employers must allocate such salary reduction deferral amounts to the type of compensation (i.e., gross amounts of regular wage payments or gross amounts of supplemental wage payments) actually being deferred.
(iii) Optional de minimis exception for certain payments by agents.
For purposes of paragraph (a)(2) of this section, if an agent makes total wage payments (including regular wages and supplemental wages) of less than $100,000 to an individual during any calendar year, an employer or other agent may disregard such payments in determining whether the individual has received $1,000,000 of supplemental wages during the calendar year, and such agent need not consider whether the individual has received other supplemental wages in determining the amount of income tax to be withheld from the payments. An employer may not avail itself of this exception if the employer is making payments to the employee using five or more agents and a principal effect of such use of agents is to reduce the applicability of mandatory flat rate withholding to the employee. For purposes of paragraph (a)(2) of this section, if an agent makes total wage payments of $100,000 or more to an individual during any calendar year, the entire amount of supplemental wages paid by the agent during the calendar year to the employee must be taken into account (by other agents of the employer that make total wage payments to the employee of $100,000 or more, by the agent, and by the employer for which the agent is acting) in determining whether the employee has received $1,000,000 of supplemental wages.
(iv) Treatment of supplemental wage payment exceeding $1,000,000 cumulative threshold.
In the case of a supplemental wage payment that, when added to all supplemental wage payments previously made by the employer to the employee in the calendar year, results in the employee having received in excess of $1,000,000 supplemental wages for the calendar year, the employer is required to impose withholding under paragraph (a)(2) of this section only on the portion of the payment that is in excess of $1,000,000 (taking into account all prior supplemental wage payments during the year). However, an employer may subject the entire amount of such supplemental wage payment to the withholding imposed by paragraph (a)(2) of this section.
(5) Withholding on supplemental wages that are not subject to mandatory flat rate withholding.
To the extent that paragraph (a)(2) of this section does not apply to a supplemental wage payment (or a portion of a payment), the amount of the tax required to be withheld on the supplemental wages when paid shall be determined under the rules provided in paragraphs (a)(6) and (7) of this section.
(6) Aggregate procedure for withholding on supplemental wages—
(i) Applicability.
The employer is required to determine withholding upon supplemental wages under this paragraph (a)(6) if paragraph (a)(2) of this section does not apply to the payment or portion of the payment and if paragraph (a)(7) of this section may not be used with respect to the payment. In addition, employers have the option of using this paragraph (a)(6) to calculate withholding with respect to a supplemental wage payment, if paragraph (a)(2) of this section does not apply to the payment, but if paragraph (a)(7) of this section could be used with respect to the payment.
(ii) Procedure.
Provided this procedure applies under paragraph (a)(6)(i) of this section, the supplemental wages, if paid concurrently with wages for a payroll period, are aggregated with the wages paid for such payroll period. If not paid concurrently, the supplemental wages are aggregated with the wages paid or to be paid within the same calendar year for the last preceding payroll period or for the current payroll period, if any. The amount of tax to be withheld is determined as if the aggregate of the supplemental wages and the regular wages constituted a single wage payment for the regular payroll period. The withholding method used by the employer with respect to regular wages would then be used to calculate the withholding on this single wage payment and the employer would take into consideration the Form W-4 submitted by the employee. This procedure is the aggregate procedure for withholding on supplemental wages.
(7) Optional flat rate withholding on supplemental wages—
(i) Applicability.
The employer may determine withholding upon supplemental wages under this paragraph (a)(7) if three conditions are met—
(B)
The supplemental wages are either not paid concurrently with regular wages or are separately stated on the payroll records of the employer; and
(C)
Income tax has been withheld from regular wages of the employee during the calendar year of the payment or the preceding calendar year.
(ii) Procedure.
The determination of the tax to be withheld under paragraph (a)(7)(iii) of this section is made without reference to any payment of regular wages, without allowance for the number of withholding allowances claimed by the employee on Form W-4, and without regard to whether the employee has requested additional withholding on Form W-4. Withholding under this procedure is optional flat rate withholding.
(iii) Rate applicable for purposes of optional flat rate withholding.
Provided the conditions of paragraph (a)(7)(i) of this section have been met, the employer may determine the tax to be withheld—
(A)
From supplemental wages paid after April 30, 1966, and prior to January 1, 1994, by using a flat percentage rate of 20 percent;
(B)
From supplemental wages paid after December 31, 1993, and on or before August 6, 2001, by using a flat percentage rate of 28 percent;
(C)
From supplemental wages paid after August 6, 2001, and on or before December 31, 2001, by using a flat percentage rate of 27.5 percent;
(D)
From supplemental wages paid after December 31, 2001, and on or before May 27, 2003, by using a flat percentage rate of 27 percent;
(E)
From supplemental wages paid after May 27, 2003, and on or before December 31, 2004, by using a flat percentage rate of 25 percent; and
(F)
From supplemental wages paid after December 31, 2004, by using a flat percentage rate of 28 percent (or the corresponding rate in effect under section 1(i)(2) for taxable years beginning in the calendar year in which the payment is made).
(8) Examples.
For purposes of these examples, it is assumed that the rate for purposes of mandatory flat rate withholding for 2007 is 35 percent, and the rate for purposes of optional flat rate withholding for 2007 is 25 percent. The following examples illustrate this paragraph (a):

(9) Certain noncash payments to retail commission salesmen.
For provisions relating to the treatment of wages that are not subject to paragraph (a)(2) of this section and that are paid other than in cash to retail commission salesmen, see § 31.3402(j)-1.
(10) Alternative methods.
The Secretary may provide by publication in the Internal Revenue Bulletin (see § 601.601(d)(2)(ii) (b) of this chapter) for alternative withholding methods that will allow an employer to meet its responsibility for the mandatory flat rate withholding required by paragraph (a)(2) of this section.
(b) Special rule where aggregate withholding exemption exceeds wages paid.
(1)
This rule does not apply to the extent that paragraph (a)(2) of this section applies to the supplemental wage payment. If supplemental wages are paid to an employee during a calendar year for a period which involves two or more consecutive payroll periods, for which other wages also are paid during such calendar year, and the aggregate of such other wages is less than the aggregate of the amounts determined under the table provided in section 3402(b) (1) as the withholding exemptions applicable for such payroll periods, the amount of the tax required to be withheld on the supplemental wages shall be computed as follows:
Step 1. Determine an average wage for each of such payroll periods by dividing the sum of the supplemental wages and the wages paid for such payroll periods by the number of such payroll periods.
Step 2. Determine a tax for each payroll period as if the amount of the average wage constituted the wages paid for such payroll period.
Step 3. From the sum of the amounts of tax determined in Step 2 subtract the total amount of tax withheld, or to be withheld, from the wages, other than the supplemental wages, for such payroll periods. The remainder, if any shall constitute the amount of the tax to be withheld upon the supplemental wages.

(2) Applicability.
The rules prescribed in this paragraph (b) shall, at the election of the employer, be applied in lieu of the rules prescribed in paragraph (a) of this section except that this paragraph shall not be applicable in any case in which the payroll period of the employee is less than one week or to the extent that paragraph (a)(2) of this section applies to the supplemental wage payment.
(c) Vacation allowances.
Amounts of so-called “vacation allowances” shall be subject to withholding as though they were regular wage payments made for the period covered by the vacation. If the vacation allowance is paid in addition to the regular wage payment for such period, the rules applicable with respect to supplemental wage payments shall apply to such vacation allowance.
