Manufacturing & Job Shops Bookkeeping in Michigan

Nearly every sales tax state exempts something for manufacturers — production machinery, consumables used up in production, sometimes utilities metered to the production floor — but what qualifies, and what paperwork proves it, is set by Michigan and administered by the Michigan Department of Treasury. No local sales tax, and sales and use tax are reported on a combined return with withholding. The exemption is claimed with a certificate at the time of purchase, which means it is effectively lost if nobody presented one, and recovering overpaid tax afterwards is a refund claim rather than an adjustment. Keeping the certificates on file and current is a bookkeeping task with a direct cash value.

Use tax is the manufacturer's recurring exposure in Michigan. Equipment, tooling, and supplies bought from out-of-state vendors who did not charge Michigan tax still carry an obligation at 6% plus local, and the Michigan Department of Treasury expects it to be self-assessed and remitted. A shop buying machinery, fixtures, and consumables across state lines accrues real liability here without a single invoice showing it — which is why the accrual belongs in the monthly close rather than in an annual reconstruction.

Economic nexus in Michigan is $100,000 in sales or 200 transactions. For manufacturing and job shops, 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.

Registering to do business in Michigan runs through the Michigan Department of Licensing and Regulatory Affairs, with tax accounts through the Michigan Department of Treasury and employer accounts through the Michigan Unemployment Insurance Agency. Michigan treats these as wholly independent, so being in good standing with one says nothing about the others — and the sales tax account is the one that accrues a real balance while you are not looking.
