Why Don't I See a City Field in My Tax Profile?
The city field only appears for states that have local (city-level) income tax — not every state does. If your state doesn't have local income tax, Flux skips the city question automatically since there's nothing to configure.

If you change your state in your tax profile, Flux re-checks this — the city field will appear or disappear depending on the new state's local tax status, and any previously selected city clears.
