What's in the Iowa rate file

Iowa data ships inside every edition — we do not sell single-state files. Each row carries the ZIP code, county and city name, the rate at each jurisdiction level, the combined total, and whether shipping is taxable. The higher editions add district reporting codes, FIPS codes, effective dates and sales tax holiday windows.

Research

Official Iowa sales tax resources

Every link below goes to an official Iowa government source, not to us. The state is always the authority — our file is how you avoid checking it by hand every month.

How local tax works in Iowa. State-collected. The Department administers the voter-approved Local Option Sales Tax alongside the 6% state rate and distributes receipts back to cities and counties on one combined return.

Worth knowing. Local option tax is adopted jurisdiction by jurisdiction and can sunset, so rates change on a rolling basis. Iowa steers users to the Tax Mapper by address rather than by ZIP.

Questions

Iowa sales tax questions

What is the sales tax rate in Iowa?

The statewide base rate is 6%. Local jurisdictions add their own rate on top, so the rate you must actually charge is almost never the state rate.

Is shipping taxable in Iowa?

Generally no. In Iowa a delivery charge is not taxable, and combining it with handling does not make it taxable.

That distinction catches people out, which is why our file carries both flags — TAX_SHIPPING_ALONE and TAX_SHIPPING_AND_HANDLING_TOGETHER — on every row, for the specific jurisdiction. Your system doesn't have to encode the rule.

How many sales tax jurisdictions are there in Iowa?

We track 1,114 bodies that actually levy a sales tax in Iowa — 2 counties and 1,112 cities — across 1,054 IA ZIP codes. We count a county, city or district only where it charges something, not merely because it appears in the file.
