<prompt> Human: Hi PF,I have a significant amount of money invested in a taxable account. Almost all low fee index funds. I have an employer that has a 401k. Im allowed to dump 18kyear into this account and deduct it from my taxes. The only funds available have 1-2 fees attached to them. Im concerned about the fees, but Im more concerned about letting my employer know how much money Im investing. I think it could influence future raises rich guy doesnt need any more money. Considering fees and taxes, how much am I missing out on by keeping my money in taxable accounts. Im in 25 marginal tax bracket but could easily move up depending on returns in dividends, REIT and junk bond funds. Im already maxing out Roth IRA. Total investments in taxable accounts are around 380k. Thanks in advance for your advice.  <response>: This is just straight up paranoia.
