Colorado did not get more expensive by accident, and you have watched it happen from the inside. Denver-area medians ran hard, the Front Range filled in, I-25 got worse every year, and the TABOR refunds that used to soften the state income tax quietly stopped arriving.
The result is a flat 4.4 percent income tax that is closer to a true 4.4 percent than it was five years ago, paired with a housing market that priced out the people who moved there for it. On a $150,000 household income that is over five thousand dollars a year going to the state before you have paid a mortgage. Texas charges nothing.
What makes the North Texas comparison work is not just the tax line. It is that the housing gap is real across most of the metroplex, the job base is diversified across finance, telecom, aviation, healthcare, logistics, and defence rather than concentrated, and two major airports remove the DIA drive from your life entirely.
You give up the Rockies, and Coloradans consistently tell me they miss looking west more than they miss any specific ski day. That is worth taking seriously before anything else on this page. Winter here is the compensation, and for most families it turns out to be a bigger one than they expected.
Tax rates and refund mechanisms change. Housing comparisons vary substantially by origin metro and target submarket. General information, not legal, tax, or financial advice.
