I've contributed $2000 to my Roth 401(k) plan through my employer, and $4000 to my Roth IRA plan that is totally separate from my employer. My accountant says that the limit on Roth IRA contributions is $5000 for my age and says that I've over-contributed by $1000 and need to withdraw the excess.
Is he correct? Do Roth 401(k) and Roth IRA plans share the same $5000 limit?
I was looking at this matrix on wikipedia and it doesn't say anything about them sharing contribution limits.
