Download checklist:

1. Know what is exempt and what is not

Identified which purchases become a component or ingredient of the product you sell (typically exempt as a sale for resale)CRITICALListed machinery and equipment used in manufacturing and checked whether the 1 percent privilege tax on mill machinery applies instead of full sales taxCRITICALConfirmed the per-article cap on the mill machinery privilege tax against the current statute (G.S. 105-187.51)Separated production consumables, tooling, shop supplies and office items, which are usually taxable even in a plantCRITICALReviewed utilities and fuel used in manufacturing for any special rate or exemption and how it is documentedChecked packaging that ships with the product (generally treated as part of the sale) versus reusable shipping containersDocumented a written position for each category and who approved it

2. Certificates you give your suppliers

Completed the North Carolina exemption certificate (Form E-595E) for each supplier where you buy exempt itemsCRITICALChecked that each certificate states the correct basis for exemption, not a blanket claimKept a signed copy by vendor and by exemption basis, retrievable in minutesCRITICALSet a review date for each certificate and re-issue when your products or processes changeTrained buyers not to present the certificate for taxable consumablesCRITICALConfirmed out-of-state suppliers know your exemption basis and your NC registration

3. Certificates you collect from customers

Collected a valid exemption or resale certificate before shipping tax free to any customerCRITICALValidated customer name, address, registration number and the exemption basis on every certificateRecorded certificate issue date, expiry or review date and the ship-to locations coveredHandled drop ship and third-party ship-to orders separately from the bill-to certificateDefined what happens to an order when no certificate is on file (tax is charged or the order is held)CRITICALReviewed export and interstate shipments for separate documentation instead of relying on the NC certificate

4. ERP configuration

Created a tax-exempt flag or tax code on the customer master with a reason codeCRITICALCreated tax codes for exempt ingredient purchases, taxable consumables and mill machinery privilege taxMapped item categories (raw material, component, consumable, capital equipment) to default tax treatmentCRITICALStored the certificate image or reference number against the customer and vendor recordBlocked tax-free invoicing when the certificate is missing or expiredBuilt a report of exempt sales by customer and basis that ties to the returnBuilt a report of exempt purchases by vendor that ties to the certificates you issued

5. Use tax and returns

Accrued use tax on taxable purchases where the vendor did not charge North Carolina taxCRITICALReconciled the use tax accrual account to the return every periodChecked county and transit rates for each delivery location, not only the plant addressRetained records for the period required by the Department of RevenueRan an internal mock audit of five exempt customers and five exempt vendors

Tick each item you have verified. Treat unticked critical items as gaps to close before your next sales tax return or audit. This is a working checklist, not tax advice; confirm current rules with the North Carolina Department of Revenue or your tax adviser.

How to use this checklist

Work through the five groups with your controller, buyer and ERP administrator in one sitting. Tick what you have verified, and leave the rest as an action list. Items marked critical are the ones auditors usually test first: a valid certificate behind every tax-free sale, a documented basis behind every exempt purchase, and use tax accrued where the vendor did not charge tax. Export the result as PDF to keep a dated record of your review.

Run it once per year and after any new product line
Assign an owner to each unticked item
Attach the exported PDF to your tax file

What the rules actually turn on

The question is use, not industry. Material that becomes part of the finished product is generally bought for resale and can be bought without tax on a certificate. Equipment used in production may fall under the mill machinery privilege tax of 1 percent with a cap per article instead of the full combined rate. Supplies that are consumed in the plant but do not become part of the product, such as cutting fluid, gloves or office items, are generally taxable. Always confirm the current statute and Department of Revenue guidance for your exact items.

Making the exemption provable in your ERP

Most exemption problems are data problems. If the customer master has no exempt flag, no reason code and no certificate reference, invoices go out tax free with nothing behind them. Add a tax code per treatment, default it from the item category, and block exempt invoicing when the certificate is missing. On the purchasing side, tag each purchase order line as ingredient, machinery or consumable so use tax can be accrued automatically.

Customer master: exempt flag, reason code, certificate reference, review date
Item master: category that drives default tax treatment
Purchase lines: tax code per treatment so use tax accrues
Reports: exempt sales by basis and exempt purchases by vendor

Common mistakes

Plants most often present a blanket certificate for everything a supplier sells, forget to accrue use tax on out-of-state purchases, and accept customer certificates that are expired or cover a different ship-to. Another frequent gap is treating all machinery alike without checking whether the privilege tax applies. A short quarterly review of five customers and five vendors catches most of these early.

Frequently Asked Questions

Is every purchase by a North Carolina manufacturer exempt from sales tax?

No. Exemptions depend on how an item is used. Ingredients and components that become part of the product are generally bought for resale, and certain mill machinery is subject to a reduced privilege tax. Consumables, tooling and office items are usually taxable. Confirm each category with current statute and Department of Revenue guidance.

Which certificate do I give my supplier?

North Carolina suppliers commonly accept Form E-595E, the exemption certificate, with the correct basis for exemption marked. Use it only for items that qualify, keep a signed copy, and do not present it for taxable consumables.

Do I still owe use tax if the supplier did not charge tax?

Generally yes. If a taxable item is bought without North Carolina tax being charged, the buyer accrues and reports use tax at the combined state and local rate for the delivery location. A use tax accrual account reconciled each period is the standard control.

How should the ERP handle exempt customers?

Store an exempt flag, reason code, certificate reference and review date on the customer, and block tax-free invoicing when any of them is missing or expired. Report exempt sales by basis so the figures tie to the return.

If your exemption data lives in a spreadsheet next to the ERP, we can help build a private assistant that answers 'is this customer certificate valid and current' straight from your own records, on your own servers.
