Moving from Colorado to Washington: FAQ.
Seattle tech vs Denver tech — meaningful difference?
Seattle substantially deeper. Amazon (300K+), Microsoft, Google, Meta, Zillow, Expedia. Senior tech $180-350K. Denver has Palantir, Lockheed, Google smaller operations. CO tech robust but Seattle dominates West Coast outside Bay Area. Career advancement often requires Seattle move for senior tech roles.
WA capital gains tax concern?
Only for high earners. WA 7% tax on capital gains over $262K (single) / $524K (married). Most employees don't hit threshold annually. Tech workers with major RSU vesting events hit hard. CO taxes gains as ordinary income 4.4% up to threshold, making CO advantage for smaller gains. For major wealth events, CO may actually be better than WA.
CO-WA long move cost?
1,035-1,415 miles. Full-service 3-bedroom $5,500-12,000. Delivery 3-6 days. Summer peak adds 25%. Winter mountain driving considerations. I-80/I-84 corridor heavily traveled.
