Ohio: Basing Sales Tax Rates on Zip Codes


 ZIP codes: not accurate enough anymore.

Sales tax rate changes in Ohio may only occur at the start of a quarter. The current Ohio state sales tax rate is 5.75%, and counties and regional transit authorities may each levy sales tax up to 3%. As a result, combined state, county, and transit authority rates may not exceed 8.75%.

The Ohio Department of Taxation recently updated its list sales tax rates by Ohio post offices and zip codes, effective April 1, 2014. The list is not all inclusive:

“Some Ohio municipalities do not appear on this listing because they are not large enough to have their own post offices.”

In addition, some Ohio municipalities include more than one tax jurisdiction. For example, “small portions of Delaware, Fairfield, Licking and Union Counties assess a transit authority sales tax” that may not be accurately reflected in the rates by post office.

Using a zip code to determine a sales tax rate may work. Then again, it may not. Zip codes are the wrong tool for the job, and can lead to over- and undercharging sales tax.

An automated sales tax solution gets you the right rate, every time.
