In this person’s situation, you really need a more detailed review of things.
For example, Texas does not have a state sales tax, whereas California does have sales tax.
California property tax rates are lower than many other places, but that is somewhat offset by high property values in California compared to other states.
Apparently Corpus Christi Texas has high property tax assessments, but then, those people are not paying a state income tax.
How you evaluate the financial impact of all of the combined taxes we all pay varies from person to person.
CORRECTION — Texas does not have a state INCOME tax. I don’t know about sales tax in Texas.
“Texas does not have a state sales tax”
I think you meant income tax.
Texas has a capped 8.25% sales tax, but does not have an income tax.
