The no-income-tax line is real, especially for portable income.
A California or Illinois salary goes further in Tennessee if you rent or buy carefully.
Tennessee has no state income tax on earned income. For a household keeping a coastal or Chicago salary, that is a real line item. Unlike Austin, Nashville does not take most of the savings back through high property tax. A $500,000 owner-occupied house in the Urban Services District carries roughly $3,500 in property tax before insurance, not five figures.
The catch is that the tax base moves to consumption. Nashville now lives with a 9.75 percent general sales-tax environment after the transit surcharge, and groceries still carry a reduced state food tax plus local tax. The move works best for households with high income and controlled discretionary spend.
Planning note: this is where Nashville differs from the easy relocation story. The useful question is not whether this point is true in general, but what it does to the exact address, commute, school path, and budget you are considering. A mover who can answer that before signing is reading the city correctly.
Austin comparison note: Austin usually punishes movers through property tax, heat, traffic, and a sharper tech-market housing premium. Nashville punishes vagueness differently: sales tax at the register, school-path ambiguity, older-house repairs, storm routines, and a car map that looks easier than it feels. The move is strongest when the household names which of those trades it is accepting before the search begins.
