Missouri is about 23% cheaper than Washington overall, so your budget should stretch noticeably further — especially on housing.
Washington has no state income tax, but Missouri's top rate is about 4.7%. Factor the change into your take-home pay and monthly budget.
Washington has no individual income tax, so there is no part-year return to file. It does tax long-term capital gains at 7 percent, after a standard deduction of $278,000 for 2025. Since 2025, gains above $1 million pay an extra 2.9 percent. The tax applies only to gains allocated to Washington. Under RCW 82.87.100, a gain from stock or other intangible property is allocated here if you were domiciled in Washington on the sale date. File a return if you owe the tax. Also file one if you made a payment or asked for an extension, even with no tax due.

To keep it after you move, opt in within one year of setting up your main home in another state. You need 500 contributing hours a year for three years since July 1, 2023, and no active exemption. Out-of-state benefits start July 1, 2030. You then file a wage report every year. If you stop reporting or paying, coverage ends and cannot be reinstated.

Remove or invalidate the month and year tabs first, then bend the plates. Personalized plates and some special plates must go back to DOL. You cannot recycle those.

Mail the Vehicle/Vessel Refund Application to DOL. Include a copy of your new out-of-state registration that shows the VIN and the issue date. A refund takes 1 to 3 months.

Surrender a valid license from another state, or one expired 184 days or less, and you skip the written and skills tests. Everyone takes the road sign recognition test and the vision test. A commercial driver license must transfer within 30 days.

To get plates, you also need a Missouri safety inspection unless the vehicle is exempt. The safety inspection counts as the ID/OD inspection. If a lender holds the title, send it Form 5834 to request it. The title fee is $8.50 plus a $9 processing fee. For a passenger vehicle, the plate fee depends on taxable horsepower.
Source: Missouri DOR, Titling and registrationThe license office asks for it when you first title the car. It shows that you owe no Missouri personal property tax. Get it from the assessor in your county, or the City of St. Louis. Ask the assessor to add you to the roll for next year. To renew plates later, bring a paid personal property tax receipt or a statement of non-assessment.

A vehicle is exempt for the first ten years after its model year if it has less than 150,000 miles. In St. Louis City and in Jefferson, St. Charles, and St. Louis counties, you also need an emissions inspection. Inspections must be no more than 60 days old.
