It serves as proof for the seller that they are not required to collect tax on a particular transaction because the purchaser qualifies for a specific exemption, such as for resale, use in manufacturing, or purchase by a nonprofit organization.

The AI checks your answers before you download

14 checks built for this form, so a wrong date or a missing answer is caught before anyone else sees it.

Ensures a single Certificate Type is selected

This validation confirms that the user has selected exactly one of the two certificate types: 'UNIT EXEMPTION CERTIFICATE' or 'BLANKET EXEMPTION CERTIFICATE'. It is critical to specify the scope of the exemption (one-time vs. multiple transactions) for correct tax processing by the seller. If neither or both are selected, the form is ambiguous and cannot be processed, leading to rejection.

Verifies at least one Exemption Reason is chosen

This check ensures that at least one of the exemption reason checkboxes (1 through 8) is selected. The entire purpose of the form is to declare a reason for tax exemption. A submission without a selected reason is incomplete and provides no basis for the exemption claim, making the certificate invalid.

Validates exclusive selection of a primary Exemption Reason

This check ensures that only one primary exemption reason (from checkboxes 1-8) is selected. The form instructs the user to select the 'appropriate paragraph,' implying a single basis for the claim. Allowing multiple selections could create conflicting logic and ambiguity for the seller, potentially leading to an invalid exemption and tax liability.

Conditional Requirement for Exemption Reason 2 Fields

If the checkbox for Exemption Reason #2 ('Purchaser is a/an') is selected, this validation ensures that both the 'Purchaser is a/an' text field and the 'Sales Tax Exemption Number' field are completed. These fields are essential to identify the exempt entity and its corresponding state-issued exemption number. Failure to provide this information renders the claim under this reason unverifiable and invalid.

Conditional Requirement for Exemption Reason 4 Fields

When the checkbox for Exemption Reason #4 ('Public utility service') is selected, this validation confirms that at least one of the two identification number fields, 'PA Public Utility Commission PUC Number' or 'U.S. Department of Transportation MC/MX', is filled. A public utility claim must be substantiated with a valid regulatory number. Without it, the claim lacks the necessary proof and the exemption cannot be granted.

Conditional Requirement for Exemption Reason 7 Fields

If the checkbox for Exemption Reason #7 ('Canned computer software') is selected, this check verifies that the 'Invoice Number', 'Total Software Licenses Purchased', and 'Total Users Accessing Software Outside PA' fields are all filled. This information is required for the seller to correctly apportion the tax. Incomplete data for this reason makes it impossible to calculate the exempt portion of the sale, invalidating the claim.

Common Mistakes in Completing REV-1220

The ones the AI is built to catch.

Using the Form for Vehicle Registration
A prominent note on the form explicitly states it should not be used for claiming an exemption on a vehicle registration. This mistake occurs when users see a general 'Exemption Certificate' and assume it applies to all purchases, including vehicles. Using this form for a vehicle purchase will lead to its rejection by the PA Department of Transportation, delaying the vehicle's registration and requiring the filer to restart the process with the correct form (MV-1 or MV-4ST).
Selecting the Incorrect Certificate Type (Unit vs. Blanket)
Users often fail to choose between a 'Unit' certificate for a single transaction and a 'Blanket' certificate for multiple transactions. This choice depends on the business relationship with the seller. Selecting 'Unit' for an ongoing purchasing relationship necessitates filling out a new form for every transaction, creating unnecessary administrative work. Conversely, using a 'Blanket' certificate for a one-time purchase can cause confusion for the vendor's record-keeping.
Incomplete Exemption Justification
A frequent error is checking an exemption reason (e.g., Box 2, 3, 4, or 5) but failing to provide the mandatory corresponding information, such as a Sales Tax Exemption Number, PUC Number, or License ID. The form is considered incomplete and invalid without this data, forcing the seller to charge sales tax on the transaction. To avoid this, always fill in all required fields associated with the selected exemption reason.
Missing Explanation When a License ID is Not Provided
For exemptions 3 (Resale) and 5 (Wrapping Supplies), the instructions state that if the purchaser does not have a PA Sales Tax License ID, they must provide an explanation in Box 8. Many filers overlook this and simply leave the License ID field blank, which invalidates the certificate. To prevent this, if you lack a license ID for a valid reason, you must use Box 8 to explain why one is not required for your specific situation.
Confusing Seller and Purchaser Information
The form has separate sections for the 'Name of Seller, Vendor or Lessor' at the top and the 'Name of Purchaser or Lessee' at the bottom. It is a common data entry error to accidentally enter the purchaser's information in the seller's section or vice versa. This mistake makes the certificate invalid as it incorrectly identifies the parties of the transaction, leading to rejection by the seller and potential tax liability.
Providing an EIN Instead of a Sales Tax Exemption Number
When claiming an exemption as a nonprofit or other exempt organization under Box 2, the form requires a specific Sales Tax Exemption Number (often beginning with '75'). A common mistake is to enter the organization's federal Employer Identification Number (EIN) in this field instead. The EIN is a different identifier and is not valid for this purpose, which will cause the seller to reject the certificate.
Forgetting to Sign and Date the Certificate
An unsigned or undated certificate is invalid. This oversight often happens when a form is filled out digitally and printed, or when the filer is in a hurry. The seller cannot legally accept an unsigned certificate, which means they must charge sales tax on the purchase. Always double-check that a valid signature and the current date are in the designated fields before submitting the form.
Misinterpreting 'Direct and Predominant Use'
For Exemption 1, property must be used 'directly and predominately' in an exempt operation like manufacturing or farming. Filers often misinterpret this legal standard and attempt to claim exemptions for items used in administrative, managerial, or other non-operational activities, which are explicitly disallowed. This can lead to the exemption being denied upon audit, resulting in back taxes and penalties.
Vague or Missing Explanation in 'Other' Category
When an exemption reason does not fit categories 1-7, filers must use Box 8 and provide a detailed explanation. A common mistake is to write a vague phrase like 'exempt' or 'tax-exempt purchase' without providing the specific legal or factual basis for the exemption. This lack of detail makes it impossible for the seller to validate the claim in good faith, rendering the certificate useless.
Incorrect Data for Software License Exemption
Exemption 7, for canned software used outside PA, requires three specific pieces of information: the invoice number, the total number of licenses purchased, and the number of users outside PA. Filers often leave one of these fields blank or confuse the numbers, providing incorrect data. An incomplete or inaccurate entry for this exemption will lead to its rejection, as the seller cannot properly document the basis for the tax apportionment.
