While a protocol as a whole, may be comprised of more than one header type that it uses for communication purposes to exchange information such as state and transmit application specific data. This is the reason why sometimes a protocol is described as a protocol suite.
Since January 1, 2006, U.S. employers have been allowed to amend their 401(k) plan document to allow employees to elect Roth IRA type tax treatment for a portion or all of their retirement plan contributions. The same change in law allowed Roth IRA type contributions to 403(b) retirement plans. Employees can roll their Roth 401(k) contributions over to a Roth IRA account upon termination of employment. 2  It is the employer's decision whether to provide access to the Roth 401(k) in addition to the traditional 401(k).
As I understand it, I can contribute up to $17,500 to my 401(k) per year and $5,500 to my personal Roth IRA. Thanks, -- Matt Morass. Dear Matt, Having a Roth 401(k) plan at work doesn't limit your ability to contribute to your personal Roth IRA. Depending on your income, however, you may have to fund a traditional IRA and then do a Roth IRA conversion.
