Most important one is contributing enough in your 401(k) to get the full company match. Otherwise, you are literally leaving money on the table.

Here's what NOT to do. Take out loans against your 401(k). Yes, you are paying yourself back with interest and so it sounds smart. But you are reducing the size of your paycheck (to pay it back) and will be subject to heavy penalties if you get laid off from your job and are unable to make the lump sum payment to pay it off all at once.

Another mistake people make is cashing out the 401K, when small, when switching jobs.

“you get laid off from your job and are unable to make the lump sum payment to pay it off all at once. “

Just happened to me. It was only 5k but that will go against 2016 earnings.

I hear you, Sam, but taking a loan against my 401k allowed me to say FU to lending institutions that turned me down. I’m paying myself back at 3%. It’s not for everybody, particularly if you work in the private sector.
