Seattle vs Denver: where the money goes
Use this table as a starting point. Then swap every row with your real lease, daycare, and insurance quotes.
| Topic | Seattle (WA) | Denver (CO) |
|---|---|---|
| State income tax | No state income tax on wages. Your stub may still show small program fees. | Colorado state tax on your wages. Most workers see real state withholding. |
| Housing | Puget Sound premium. Seattle and the Eastside (Bellevue, Redmond) are among the priciest US tech rents. | Front Range growth. Denver and its suburbs got pricey with new arrivals. Still cheaper than Seattle in most ZIPs. |
| Getting around | Buses, light rail, and ferries exist. But most homes still keep a car for the Eastside or mountain trips. | Mostly car-first. Snow tires, parking, and gas add steady monthly costs. |
| Hidden cost surprises | Long grey winters mean more energy use. Daycare waitlists can feel like a second rent. | Dry air and altitude (humidifiers, skin care). Hail season can spike home insurance. |
Your paystub: Washington vs Colorado
Federal tax and FICA are the same in both states. The split comes from one line. Colorado takes a state income tax. Washington does not. Washington may still take small program fees. But those are tiny next to a real state tax.

| Line | Seattle (WA) | Denver (CO) |
|---|---|---|
| Gross / mo | $9,167 | $9,167 |
| Fed + FICA | ~$2,380 | |

Colorado taxable income can differ from gross because of 401(k), HSA, and other adjustments. Washington premiums vary by employer reporting. Property tax and sales tax still exist in both states outside this wage snapshot.
Housing, altitude, and the "weekend tax"
People in both cities love the outdoors. Then they quietly pay for it. Gear, ski passes, gas, and lost Saturdays. That is not a line on Zillow. But it is why two people with the same salary can feel broke for very different reasons.
Tie it back to your monthly cash
After tax, most US homes still spend on the same things. Rent, food, car, insurance, and savings. Want a real budget picture before you move? Read average monthly expenses and salary needed to live comfortably. Then drop your Seattle and Denver numbers into those frames.
Example: Jamie at $110k — same job, two cities
Jamie has a remote role at $110,000. They can live in either city. The smart move is to follow this order:
-
Print the paycheck gap Run Washington and Colorado at the same salary. See if the Colorado tax bite is the whole story. Or just part of it.
-
Add two real rent quotes Maybe Capitol Hill vs Fremont on the Seattle side. Congress Park vs Baker on the Denver side. Pick what matches Jamie's commute and noise tolerance.
-
Be honest about lifestyle If Jamie will buy ski passes and flights out of habit, count that cash. Not "free because mountains."
If Jamie has RSUs, big bonuses, or a partner with W-2 income, this sketch breaks. That is why we link to calculators. Not one table for every worker.

Frequently asked questions
Does Washington tax wages like Colorado?
No. Washington has no state income tax on wages. Colorado does. You may still see small program fees on a Washington stub. Always read your real one.
Which city is better for remote workers?
"Better" is more than tax. It is your time zone, your travel, your childcare, and your partner's job. Check take-home pay, rent, and how you'll get around. Then decide if the lifestyle fits.
Is Seattle more expensive than Denver?
Seattle rent is usually steeper. But Denver's state tax can eat the Seattle paycheck win. The pricier city is the one with less cash left after your real bills.
Where should I start if I only have 20 minutes?
Run your salary in both calculators. Then check two real rents. One per city. If those two steps disagree with your gut, trust the math.
