The 401(k) would invalidate any previosly established SIMPLE IRA for the year. All contributions (now excess contributions) would be reflected in box 1 of Form W-2. The excess should be removed in accordance with traditional IRA rules. [See IRC 408(d)(7)(B), referring to 408(d)(4) and 408(d)(5)], However, the SIMPLE IRA excess does not appear to be subject to the 6 percent excess contribution penalty tax (even if returned after the due date).
Hope this helps.
Additional Question regarding Simple IRA exclusive plan rule...
Employer A sponsors a 401k plan and purchased 100% of the stock of corproation B in 2006. Corporation B sponsors a Simple IRA for it's 4-5 employees. For purposes of the exclusive plan rule, if $0 contributions have been made to the Corporation B's Simple IRA in 2006. Corporation A wishes to terminate the Simple IRA in 2006 and amend Corporation A's 401k plan to include employees of Corportion B as eligible participants in Corporation A's 401k plan during the 2006 plan year, correct? The affect to the Simple IRA in 2006 would be moot since there are $0 "excess contributions" to return, correct?
