401k and dividend tax

I was wondering how 401k plans treat diviedend tax.

Like if I hold a mutual fund in my 401k that mutual fund pays some
type of tax on the dividends on the stock it owns.  Do I as an
investor in that fund thru the 401k end up paying dividend taxes
indirectly even though the mutual fund is in a 401k ???

Just wondering if the person that invests through a 401k is treated
differently then the person that invests in the same mutual fund but
not thru a 401k...

thanks!
