6/30 PYE 401k - safe harbor needed every other year?

[Santo Gold]

Small 401(k) plan operates on a 7/1 - 6/30 plan year. if the plan is safe harbor (3%) for 04/05 plan year, can the owners (they are the only hce's) make 401k contributions of $13,000 in 2nd half of 2004, and then $14,000 in first half of 05? Then, skip the safe harbor for the 05/06 plan year, in which the owners make $0 401(k) contributions. For 06/07, back to safe harbor, with the owners again doing double 401k? Do you see any problems in doing this?

Thanks

That would be fine. The only problem you will face is having to amend the plan every year.
