TRS 3 Defined Benefit information:First, the State Supreme Court ruled on the gain sharing case. That benefit was repealed, so if your wife is willing to forgo the ability to work part-time (for a public employer) until age 65, she can collect her defined benefit under the "2008 ERRF" (shown on the screenshot). At age 57 (with 30 years of service) she would be eligible for 86% of her benefit. At age 60 (as your screenshot shows) she can get 95% of her benefit. And she could also collect 98% at age 61 or 100% at age 62. (Just to be really clear, I mean 86%-100% of her benefit, not that percentage of her salary...so for example 86% of 30% of her pay, i.e. 25.8% of her salary). So unless she wants to, say, substitute teach, there's no reason for her to delay taking that monthly check any later than age 62. And if she retires at 57 with 30 years of service, her benefit will grow by 3% per year (again, 3% of 30% of pay, not 3% of pay) until she collects it at age, age 62 or whenever. The online calculator should incorporate all of these factors, so play around a little to see how the benefit estimate changes. (Repeated caveat: it's just an estimate.)
TRS 3 Defined Contribution information:Unfortunately, I can't help with the contribution rates for defined compensation. Your wife appears to be enrolled in Option D, which is a flat 7% of pay at any age and unless she changes employers that's her rate. I believe that there was an attempt to allow TRS 3 members to change rate options, but the IRS clamped down on that. I think the IRS was concerned about people reducing savings rates in bad times but it also precludes people from saving more. Not much to be done there, I'm afraid. If you want advice on how to invest it, you'll find a lot of opinions in the investors' forums. You could also post there for opinions on these funds:
http://www.icmarc.org/washingtonstate/investments/fund-descriptions.htmlYou do have the defined benefit as a safety net of sorts but only you and your wife can decide how much risk you're comfortable accepting in the hope of getting higher returns.
As for collecting money from the defined contribution (DC) account, that is permitted at any age upon separation from covered employment. That means she has to quit her job and not immediately take another state or local government job. If she chooses to access it, there are a range of options including rollover into an IRA or purchasing an annuity. (Correction to my previous statement: I believe the TAP annuity can be purchased even if your wife self-directs her investments - please check into this - there is a calculator on the web site and the terms are very nice...currently the payment is calculated using a 7.8% rate of return assumption.)
The income is taxable in any case unless you do a rollover to a tax-deferred accoutn, but you won't pay the additional 10% income tax penalty on disbursements if your wife: (a) doesn't separate (quit) from work with an eligible employer until the year *after* she turns 55; or (b) doesn't actually withdraw the money until after 59 1/2. I believe that annuities or level withdrawals (of the type that 401k owners use to avoid this penalty, I think...I am not very familiar with private sector plans) are also exempt from penalty. Again, check with DRS and/or ICMARC and/or an account/lawyer before relying on this. Laws change.
Some other, smaller things to consider:(1) While this generally isn't as important as it was before the health care exchanges started popping up, your wife will have the option to buy health coverage through the state employees' insurance pool. The costs aren't low, but the coverage is good. Ask DRS or the state Health Care Authority for more information if you are interested. There are limits on when you can opt in, so if this matters to you I again encourage you to check with DRS/HCA. DRS has a 1-800 number. I can dig it up if you would like me to.
(2) TRS 3 members, like other members of PERS/TRS/SERS plans, have the option at the time of retirement (meaning applying to receive their defined benefit) of purchasing up to 5 years of additional service credit. Unfortunately, this credit can't in turn be used to qualify for retirement or other benefits. It's effectively another option to purchase a supplemental annuity from the retirement plan. Like the TAP annuity, you end up with an extra monthly check, COLAs, etc. Unlike the TAP Annuity, it is linked directly to (is a part of) your defined benefit, so you can't take it before you retire officially. It may or may not be of interest to you. If it is, look into it when your wife is closer to retirement.
Do you and your wife have a particular timeframe in mind for retiring (stopping work, I mean)?
