Did you just get a letter from your employer about a “True Up” matching change and wondered what the heck that meant? Let me explain what that probably means, though you’ll have to talk to your company HR to find out for sure. Essentially what happens is that when you contribute to your 401k and get a match from your company, they will only match up to a percentage of your monthly paycheck. If you get a 3% match on a 3% contribution and make $1,000 per month, if you contribute $30 then the company kicks in $30. If you put in $100, the company only puts in $30.
Now, let’s say you make $10,000 (and there is no highly compensated employee clause, for simplicity’s sake), and you contribute 50% of your salary to your 401k. By March (three months in), you’ll have hit the maximum contribution to your 401k ($15,500 for 2007). However, your 401k administrator will only have given you 3% each month which is only $1,200. If you had spread your 401k contributions across the 12 months, you’d have gotten a match of $3,600. If your 401k offered a True Up Match, they’d have the employer kick in the other $2,400 at the end of the year so that you get the “true” employer match.
This allows you to contribute as much as you want, whenever you want, and not be worried that some tricky math accounting would mess with your employer match.
