I don't believe there is a time limit--an annulment declares that a marriage was invalid. See RCW 26.09.040 apps.leg.wa.gov
You have to be able to prove the marriage was invalid due to one of the reasons. It is much easier to get a divorce. And divorces are easily (and fairly quickly--90 days) obtained in WA. It will be much more difficult and expensive to have the marriage annulled.
