If you were on active duty when you received the bonus, and the bonus amount was included in Box 1 of your military W-2, it is considered military pay and is taxable only by your State of Legal Residence (SLR) - Washington, in your case (which of course has no income tax). It is not taxable by the state in which you happen to be stationed.
