Some of my favorite customers are moving to Washington state to be closer to their daughter's family. They're moving close to the Oregon state line. They say that Washington has no state income tax and that Oregon has no sales tax. They claim that they can live in and work in Washington without paying any state income tax and can drive 30 minutes across the state line into Oregon to buy everything they need without having to pay any sales tax? Does this sound too good to be true? Is it true? Why aren't we all moving there?
