Buying Wyoming WRS service: up to 5 years, one time

Buying service raises your Wyoming Retirement System (WRS) pension and can bring your Rule of 85 date closer. Here are the rules.

Short answer: if you're an active, vested member, you can buy up to 5 years of WRS service one time (8 in all for honorably discharged veterans). Bought years count in the formula and can bring the Rule of 85 up to 2.5 years sooner, but never change your tier. To see what extra years do, add them to your service in the calculator.

Active, vested members may make a one-time purchase of up to 5 years of service credit. Honorably discharged U.S. military veterans may buy more (one year per year of military service), up to 8 years in all. The price is a lump sum equal to the actuarial equivalent of the added benefit at your age (WRS quotes it). Pay with personal funds or a pre-tax rollover (not after-tax or Roth money). Purchased service counts toward the benefit and the Rule of 85 (it can bring the Rule of 85 up to 2 1/2 years sooner) but never changes your tier; military purchased service does not count toward vesting. Handbook p. 10, Increasing Your Pension Benefit via a Service Purchase; W.S. 9-3-415(d), (m)(i)-(vii)

Why "up to 2.5 years sooner"While you work, your age and your service both rise, so you gain 2 points a year toward 85. Buying 5 years adds 5 points at once, which is 2.5 years of work. Our example: 50 with 22 years reaches 85 on February 1, 2033. With 5 years bought: August 1, 2030. Handbook p. 10, Increasing Your Pension Benefit via a Service Purchase

Military deployment

Members called to active military service while contributing can get service credit for the deployment if they return to the pre-deployment WRS employer after honorable discharge, provide a DD-214 and pay the missed employee contributions (the employer pays its share). Handbook p. 26, Military Deployment; W.S. 9-3-417(c)

Service you took a refund for

If you took a refund and return to a WRS employer, you can redeposit to restore the forfeited service: wait two years after re-employment, then pay a single lump sum (set by WRS) within ten years of re-employment. Pre-tax rollovers or personal funds can be used. A redeposit made while in Tier 2 does not move you back to Tier 1. Handbook pp. 12-13, Redeposits and Important Tier 2 Rule Leaving: refund or pension?
