Manufacturing & Job Shops Bookkeeping in Maryland

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 Maryland and administered by the Comptroller of Maryland. No local sales tax. Maryland taxes certain digital products and SaaS, which catches software and subscription businesses out. 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 Maryland. Equipment, tooling, and supplies bought from out-of-state vendors who did not charge Maryland tax still carry an obligation at 6% plus local, and the Comptroller of Maryland 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 Maryland 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 Comptroller of Maryland and begin collecting. We track your Maryland sales against it and tell you before you cross, not after.

Registering to do business in Maryland runs through the Maryland State Department of Assessments and Taxation, with tax accounts through the Comptroller of Maryland and employer accounts through the Maryland Department of Labor. Maryland 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.
