"Sec. 12   RCW 29A.40.091 and 2004 c 271 s 135 are each amended to read as follows:
     The county auditor shall send each absentee voter a ballot, a security envelope in which to seal the ballot after voting, a larger envelope in which to return the security envelope, and instructions on how to mark the ballot and how to return it to the county auditor. The instructions that accompany an absentee ballot for a partisan primary must include instructions for voting the applicable ballot style, as provided in chapter 29A.36 RCW. The larger return envelope must contain a declaration by the absentee voter reciting his or her qualifications and stating that he or she has not voted in any other jurisdiction at this election, together with a summary of the penalties for any violation of any of the provisions of this chapter. The return envelope must provide a box the voter may check to indicate that he or she is a member of the armed forces. The return envelope must provide space for the voter to indicate the date on which the ballot was voted and for the voter to sign the oath. A summary of the applicable penalty provisions of this chapter must be printed on the return envelope immediately adjacent to the space for the voter's signature. The signature of the voter on the return envelope must affirm and attest to the statements regarding the qualifications of that voter and to the validity of the ballot. For out-of-state voters, overseas voters, and service voters, the signed declaration on the return envelope constitutes the equivalent of a voter registration for the election or primary for which the ballot has been issued. The voter must be instructed to either return the ballot to the county auditor by whom it was issued or attach sufficient first class postage, if applicable, and mail the ballot to the appropriate county auditor no later than the day of the election or primary for which the ballot was issued.
     If the county auditor chooses to forward absentee ballots, he or she must include with the ballot a clear explanation of the qualifications necessary to vote in that election and must also advise a voter with questions about his or her eligibility to contact the county auditor. This explanation may be provided on the ballot envelope, on an enclosed insert, or printed directly on the ballot itself. If the information is not included, the envelope must clearly indicate that the ballot is not to be forwarded and that return postage is guaranteed."
