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).
1. There are restrictions on how much you can contribute to different accounts. The 2015 contribution limit for a 401(k) is $18,000; $24,000 if youâre 50 and over. Then you can also deposit up to $5,500 in a Roth or traditional IRA for 2015 ($6,500 if youâre 50 and up).Thatâs the combined limit for both types of IRAs, by the way.You canât put, say, $5,500 each into an IRA and a Roth IRA. If youâre maxing out your 401(k) and have more to save, opening a Roth IRA can help you sock away another $5,500 or $6,500 a year (for restrictions, see below).or example: You can fund a 401(k) (or other employer-sponsored plan, including a SEP-IRA) and a Roth IRA. This enables you to save more, and gives you the tax flexibility mentioned above. You can also throw a traditional IRA into that mix.
