If you're going to work in WA, it's best to also live there. Between saving on your costs in transportation (wear and tear on the car, gas, etc), you also save yourself having to pay the Oregon income tax. OR taxes all their residents, regardless of which state their income was earned. They also tax non-residents if they work in Oregon. Another thing to keep in mind is that many people living in WA and working in OR do so because the wages in Portland tend to pay higher, enough to offset the income tax paid by non-residents.
Heck, at one time, Oregon even tried to tax spouses of non-residents who worked in Oregon, no matter where that non-resident spouse worked. Imagine that you work in Oregon, your wife works in Vancouver, and you both reside in Vancouver. Oregon wanted to not only tax
your income, but also that of your spouse who works in WA. Yeah, didn't go over well.
Here's a break down on 4 living/taxing scenarios:
Living in OR and working in WA you'll pay:- Oregon income tax (because you're taxed if you live there even if your work is in another state)
- WA sales tax on any items you purchase in WA (But you can avoid the WA sales taxes simply by showing your OR ID when going to purchase an item in WA.)
- Oregon property taxes if you own your home
Living in WA and working in OR you'll pay:- Oregon income tax (because Oregon also taxes everyone who works in the state, no matter where they live)
- Washington property taxes if you own your home
- Washington sales taxes on your purchases in WA (You can avoid sales taxes if you cross over into OR to do your shopping.)
If you live and work in OR you'll pay:- Oregon income tax
- Oregon property tax
If you live and work in WA you'll pay:- Property taxes if you own your own home
- Sales tax if you purchase items in WA (You can avoid sales taxes if you cross over into OR to do your shopping.)
Also, if you have kids or if kids will be a consideration in the future, most Clark County schools have significantly better tax bases than their Oregon counterparts. School funding is a fairly major issue for many Oregon school districts.
