OLYMPIA, Wash. (AP) — The Washington House has approved a capital gains tax on the sale of high-profit stocks and bonds, but its future in the Senate is unclear following changes Democrats made in a House committee. The measure would impose a 7% tax on the sale of stocks, bonds and other high-end assets in excess of $250,000 for both individuals and couples. Retirement accounts, homes, farms and forestry would be exempt. The measure would take effect Jan. 1 and is expected to bring in about $450 million a year. Opponents have argued that it’s a tax on income that is illegal in the state, and the debate is certain to end up in court if it becomes law.
