Pennsylvania REV-571 -- Schedule C-SB — Small Business Exemption is a form used by small businesses in the state of Pennsylvania to apply for and receive a sales and use tax exemption. The exemption applies to purchases of taxable goods and services made by a business that meets certain criteria. The criteria include: the business must have an annual gross receipts of less than $7 million, it must have fewer than 50 employees, and it must not be a part of a controlled group. The exemption applies to all purchases of taxable goods and services, including the sales of tangible property, digital products, services, and rentals. Depending on the type of business, there are two versions of the form: the general version and the version for certain regulated businesses. The general version of the form requires businesses to provide information about their business, including their name, address, and contact information. The regulated version requires additional information, such as a copy of the business' license, a description of the business' operations, and a list of the types of items the business purchases.
