Suppose that I change jobs halfway through the year.
- My first employer matches 50% of 401k contributions. By the time I leave, I've already contributed enough to hit IRS limits: $18,000 in my contributions with $9,000 matching.
- My second employer also matches 50%. They allow me to contribute another $18,000 with another $9,000 matching.
All contributions and matching vest immediately. I withdraw the $18,000 from my second employer to avoid the 401k over-contribution penalty. What happens to the second $9,000 matching contribution?
