Much like the Roth IRA, the Roth 401(k) is funded upfront with after-tax dollars. Once you hit age 59.5 you are able to start withdrawing from the account tax-free. The edge the Roth 401(k) has over its IRA cousin is that the 401(k) contribution limits still apply to the 401(k) version.Meaning that you can contribute a full $17,000 per year to the Roth 401(k) while you are limited to just $5000 in the Roth IRA.So the Roth 401(k) is great just like the Roth IRA except that weâre able to contribute A LOT more money to it each year.f you decide to contribute to a Roth instead of a your Traditional 401(k) you can expect your tax bill to go up in April because youâll be contributing after tax dollars instead of pre-tax as you had been. If you have a Roth 401(k) available to you definitely take the time to consider your options.
