Is Roth 401k contributions the same as Roth IRA?

[VolvoGirl]

No.  401K Contributions come out of your paychecks.  You only enter it from your W2.

 IRA Contributions you make yourself outside of work.  You do enter IRA under Deductions & Credits.  

[Opus 17 · Accepted solution]

A 401(k) must be sponsored by an employer, and the only way to make contributions is via payroll deduction.  

An IRA is a private account you set up with a bank, stock broker or investment advisor.  

A Roth IRA and a "Roth" 401(k) (a post-tax 401(k)) are similar in that you contribute money after taxes--you pay taxes on the money now and don't take a tax deduction for contributions.  When you retire, you withdraw the money tax-free.

However, a Roth IRA and a post-tax 401(k) have different contribution rules, different contribution limits, and different withdrawal rules.

Do you have a specific question?
