If this is an employer-initiated change, and not an employee election, why can't the EMPLOYER amend the plan to change (i.e., increase or decrease) the amount to be contributed for the year even after the beginning of the year (if the plan allows)?
As long as the plan is amended by the end of the year the increased contribution is made, you should be able to do it, provided there are no games being played. The applicable regs:
§1.409A-1(c)(3)(vi) Plan amendments. In the case of an amendment that increases the amount deferred under a nonqualified deferred compensation plan, the plan is not considered established with respect to the additional amount deferred until the plan, as amended, is established in accordance with paragraph (c)(3)(i) of this section.
§1.409A-1(c)(3) Establishment of plan--(i) In general. A plan does not satisfy the requirements of section 409A and this section and §§1.409A-2 through 1.409A-3 and §§1.409A-5 through 1.409A-6, unless the plan is established and maintained by a service recipient in accordance with the requirements of this section, §§1.409A-2 through 1.409A-3 and §§1.409A-5 through 1.409A-6. For purposes of this paragraph (c)(3), a plan is established on the latest of the date on which it is adopted, the date on which it is effective, and the date on which the material terms of the plan are set forth in writing. The material terms of the plan may be set forth in writing in one or more documents. For purposes of this paragraph (c)(3)(i), a plan will be deemed to be set forth in writing if it is set forth in any other form that is approved by the Commissioner. The material terms of the plan include the amount (or the method or formula for determining the amount) of deferred compensation to be provided under the plan and the time and form of payment.
Notwithstanding the foregoing, a plan will be deemed to be established as of the date the participant obtains a legally binding right to a deferral of compensation, provided that the plan is otherwise established under the rules of this paragraph (c)(3)(i) by the end of the taxable year of the service provider in which the legally binding right arises, or with respect to an amount not payable in the year immediately following the taxable year of the service provider in which the legally binding right arises (the subsequent year), the 15th day of the third month of the subsequent year.
