Frequently Asked Questions
Can a nonprofit be exempt from sales tax?
Often, but it is a state-level decision. Many states require a separate application or exemption certificate even after the IRS recognizes an organization as tax-exempt. We can help you apply for the state exemption and keep the paperwork current.
What is a sales tax exemption certificate?
It is a form a buyer gives a seller to document why a purchase is not subject to sales tax, such as a resale, manufacturing or nonprofit exemption. Requirements and form names vary by state. Sellers who accept a valid, complete certificate are generally protected if the state later audits the sale.
How long do I need to keep exemption certificates?
Retention periods are set by each state, and many tie them to the audit statute of limitations, often three to four years or longer. Keeping certificates organized and easy to retrieve is the best protection in an audit, and we can help you set up a system for it.
Who qualifies for sales tax exemption?
Common exemptions cover purchases for resale, certain manufacturing and agricultural inputs, and purchases by qualifying nonprofits and government entities. Rules differ by state, and federal 501(c)(3) status does not automatically create a state sales tax exemption. We check the rules for each state where you operate.
