A change in Washington state law approved by its legislature may make trips there a bit more taxing for Alaskans hoping to score an exemption from the statewide 6.5% sales tax.

According to the Seattle Times, tax bills passed last week to raise more than $830 million in revenue over two years include modifications to rules allowing residents of Alaska and five other U.S. states to request sales-tax exemptions on most goods intended for use outside of Washington.

The Oregonian reported that under the revised laws, visitors would have to save their receipts and apply annually for a rebate from the Washington Department of Revenue — which would only occur if the taxes total $25 or more.

According to the Columbian, the changes came as a surprise to store owners in southwest Washington, who rely on Oregonians crossing the border to make tax-free purchases. Washington business groups opposed the bill, which passed Washington’s House on a 55-43 vote and its Senate on a 25-22 vote.

The Washington State Legislature’s website listed the bill as delivered April 30 to Gov. Jay Inslee. As of Monday, it was awaiting his signature to become law.
