City 31890 sales tax rate, Iowa
The City 31890 city, town or village sales and use tax rate in Iowa is 0% (general rate, intrastate sales) on 2026-10-22 (effective 2019-01-01), in the state's Streamlined Sales Tax rate file IAR2025Q3MAY30.
It is a local rate: the rate on a sale where it applies adds it to the Iowa state rate of 6% and any other local rate that applies there, so the combined rate depends on the location.
A published rate is not the tax due on a sale: taxability, sourcing, nexus and exemptions all change what is owed.

- These are published sales and use tax rates by jurisdiction. They are not the tax due on a transaction and not a taxability determination: whether an item is taxable, which location's rate applies (sourcing), whether the seller must collect (nexus) and any exemption all change what is owed. Rates come from the Streamlined Sales Tax files the states publish or, where a result's source says so, from the state revenue department's own files and pages; confirm with the state before relying on them.
