E-Commerce & Online Sellers Bookkeeping in Ohio

Economic nexus in Ohio is $100,000 in sales or 200 transactions. For e-commerce & online sellers, that threshold is the one to watch, because it is reached by selling into the state — no office, no staff, no physical presence required. Once you cross it you are expected to register with the Ohio Department of Taxation and begin collecting. We track your Ohio sales against it and tell you before you cross, not after.

Marketplace facilitator rules mean large platforms generally collect and remit Ohio tax on sales made through them. Your own site, wholesale, and direct sales are a different matter — those remain yours to collect and report. Keeping the two streams separate in the books is what makes the Ohio Department of Taxation return match reality.

The Ohio statewide base rate is 5.75%. Local rates stack on top and are generally sourced to the delivery address, so the effective rate varies within the state. Getting sourcing right is what keeps the liability account matching what you actually collected.

Ohio assigns filing frequency by liability — monthly or semiannually by liability. Because Ohio includes an annual bracket, a low-volume seller here can go a full year between filings, which is exactly when a liability account drifts unnoticed. We reconcile it monthly regardless of when the return is due.
