Monitoring deferral limits.
(1) Can contributions in Plan 3 affect my deferral limits in other tax-deferred plans? Yes. Contributions to Plan 3 reduce your taxable income; this may affect your deferral limits if you participate in another tax deferred program that has a maximum contribution based on a percentage of your taxable income. You should consult with the Internal Revenue Service, a tax advisor, or a financial advisor regarding all questions of federal or state tax implications arising from participation in Plan 3.
(2) Who is responsible for ensuring that I do not exceed my tax deferral limits? Both your employer and you are responsible for ensuring that you do not exceed your tax deferral limits:
(a) Employers are responsible for monitoring to ensure that the contributions you make to your employer-sponsored tax deferred plan(s) do not exceed the limits under the Internal Revenue Code.
(b) You are responsible for monitoring to ensure that the total contributions you make to all of your tax deferred plan(s) do not exceed the limits under the Internal Revenue Code if you participate in a tax deferred program(s) outside of your employer sponsored plan(s).
