you would still pay all of your federal taxes. as well as applicable sales tax and property tax.
state tax is typically around 4-5%, depending on which state and what your income is. this is the only tax youd certainly avoid in Texas (as well as a few other states)
There are a lot of taxes that get taken out. There’s still federal income tax so that’s withheld, Medicare, and Social Security. I make under 25,000 and I only keep 80%
I live in Texas. I pay federal income taxes, medicare and SS taxes, as well as property taxes and sales tax. Sales tax is typically higher in states with no income tax - where I live its 8.25%
States still have income taxes, property taxes and all sorts of other taxes involved in generating revenue. They might not take anything *directly* from your paycheck but they're still taking your money one way or another.
In those states, you only pay Federal income taxes but no state ones.
In most states you pay your Federal taxes of, say 25% marginal tax and then also pay 3-10% in state income tax. States like Florida don't have that 3-10% tax. Also, some states have a flat tax (you pay the same amount on every dollar earned) while others have tax brackets like the Federal taxes, with higher marginal rates on higher income dollars (ie. you pay 2% on income up to $50k, but 5% on income from $50k - $100k and 7% on income above $100k).
