Retail & Brick-and-Mortar Bookkeeping in Michigan

What is taxable in Michigan is as important as the rate. No local sales tax, and sales and use tax are reported on a combined return with withholding. Item-level tax coding is where this is won or lost — a category coded wrong applies at scale, across every transaction, until someone catches it.

The Michigan statewide base rate is 6%. 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.

Michigan assigns filing frequency by liability — monthly, quarterly, or annually by liability. Because Michigan 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.

Economic nexus in Michigan is $100,000 in sales or 200 transactions. For retail & brick-and-mortar, 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 Michigan Department of Treasury and begin collecting. We track your Michigan sales against it and tell you before you cross, not after.
