Madison County's 7.00% rate sits below the statewide average of 7.14%. Across Ohio, combined rates run from 6.50% to 8.00%, so where you buy genuinely changes the bill. Ohio is unusual here: for most sales by an Ohio seller to an Ohio buyer the rate follows the seller's location, not yours (R.C. 5739.033(B)(1) sources intrastate sales to where the vendor receives the order). Out-of-state sellers and online marketplaces are the exception — they source to your delivery address, so your home county rate is the one that applies there.
