I currently have $3,978.08 in my 401k, I am switching job and wanted to know what should I do. I found out that I have the option to cash-out or rollout your 401(k) to another provider. If I cash-out what tax and penalties will I have (I live in California)?

-Roll out your 401k to another Provider. Or You're going to get KILLED with all the Taxes & Fees you'll end up Paying- if You Cash Out !! :o

It depends on what your marginal tax rate is. If you're single and your income is below about $50,000, your federal tax rate will be 15% (10% if your income is $10,000 or so). The CA state tax also varies. Say you're between $30,000 and $50,000 income, you'll pay 15% federal, 4% state, 10% early withdrawal penalty, so that's 29%, times $4,000 would be around $1,160 in taxes. You're much better off leaving it in the tax-deferred account if you can swing it.

You'll lose about 30% if you cash it out. Roll it over into an IRA.

Don't do it. It would be taxable income, plus a 10% penalty. Roll it over into an IRA. Any financial adviser could do this for you

You will lose about half that money in taxes & fees....but you will ALSO lose the potential MANY thousands it would grow into if you leave it there until you retire....

Either roll it over into your new employer's plan or into a IRA at a brokerage house...

You'll probably geet a little less than $3000.
