Pennsylvania Manufacturing Sales Tax Exemption Checklist
Pennsylvania exempts machinery, equipment and certain supplies used directly in manufacturing from sales and use tax, but you have to claim the exemption correctly and set up your purchasing and ERP so it holds up on audit. This checklist walks through the qualification test, the exemption certificate, the ERP tax codes and the credits to review.

1. Does the business qualify?
2. Which purchases are in scope?
3. The exemption certificate
4. ERP and AP setup
5. Credits and incentives to review separately
This checklist is general information, not tax advice. The Pennsylvania manufacturing exemption depends on the facts of what is used directly in the production process, and rules change. Confirm form numbers, rates and tests with the Pennsylvania Department of Revenue or a qualified tax adviser before relying on them.
Check your coding against your exemption
Optional: we can show how a private assistant could spot exempt-coded purchases that need review, using your own ERP data.
Optional. The tool and every export work without this. No spam.
How to use the checklist
Work through the five groups in order. First confirm that your activity is manufacturing as the Department of Revenue defines it. Then list the purchases that are used directly in production, and separate them from administration, storage and building costs. Next, issue the exemption certificate to vendors and store copies. Finally, make the ERP do the work: exempt tax codes, vendor flags and a use tax accrual for anything missed. Tick items as you go, then export the sheet to PDF as your working file for the tax adviser.
The core tests: directly used and production stages
The exemption turns on use, not on what the item is. Equipment used directly in the manufacturing process, from the point raw materials are first processed to the point the finished product is ready for sale, is generally eligible. Equipment used before the process starts, after it ends, or for general plant purposes usually is not. A forklift moving raw material from the dock may fail the test, where a conveyor inside the process may pass. Document each major item with the process step it supports, because auditors ask for that explanation.
- Keep a simple asset-by-asset schedule with the production step.
- Document utilities with a study or sub-meter when use is mixed.
- Treat mixed-use items conservatively and document the allocation.
ERP setup: exempt tax code and use tax
Create a zero-rate tax code for the Pennsylvania manufacturing exemption and apply it to eligible item classes and vendors. In most ERPs this means a tax code or group, a default on the item or vendor, and a GL mapping, and the terminology varies by product. Add a use tax accrual for purchases where the vendor charged no tax but the item is taxable, since the use tax obligation is yours. Finally, build an exempt purchases report by vendor and GL account, which is the first thing an auditor will request.
Common mistakes and audit risks
The usual errors are claiming the exemption on everything a plant buys, forgetting that office and warehouse purchases are taxable, not keeping certificates on file, and failing to review utilities. Another is relying on a vendor's assumption: the buyer carries the burden of showing the exemption applies. Refund claims for tax paid in error have a time limit, so review past invoices early. Credits are separate programs with their own applications, caps and deadlines, so verify them with the agency that runs them.
Frequently Asked Questions
What is the Pennsylvania manufacturing sales tax exemption?
Pennsylvania generally exempts from sales and use tax the purchase of machinery, equipment, parts and certain supplies used directly in manufacturing, processing and similar production. The claim is made by giving the vendor an exemption certificate. Whether an item qualifies depends on how it is used, so confirm with the Department of Revenue.
What form do I use to claim the exemption in PA?
Pennsylvania uses an exemption certificate, currently Form REV-1220 at the time of writing. You complete it with your sales tax license number, the exemption claimed and a description of the property, then give it to the vendor. Confirm the current version on the Department of Revenue website.
Are there Pennsylvania manufacturing tax credits?
Yes, there are several separate programs, such as the Research and Development tax credit and the Job Creation Tax Credit, plus local abatements in zones like Keystone Opportunity Zones. Each has its own eligibility, caps and application timing, so check the details with the administering agency.
What if I paid sales tax on something that was exempt?
You can generally seek a refund within the statutory time limit, from the vendor or through a claim with the Department of Revenue, depending on the situation. Gather the invoice, certificate and a description of the use. Ask a tax adviser about deadlines for your case.
If your purchase history and item master are in an ERP, we can build a private assistant on your own servers that flags likely taxable purchases coded exempt, with the query shown so your tax team can verify it.
