I mentioned top heavy because I did not want an excessive contribution on her part to trigger the 3% contribution. She is adamant she does not want to make a company contribution. It's not the plan I would have steered her to but she chose to start this plan without benefit of my advice.
The estimated 2017 profit of the her sole proprietorship is $250K. Just to clarify the timing aspect of her contribution, pursuant to Reg 1.401(k)-1(a)(6), she needs to make her election by Dec 31, 2017.
Does it need to be paid by Dec 31, 2017 or April 15, 2018 (or the extended due date of her 2017 Form 1040)?
