What is the best software to use for sales taxes? For sales tax specifically: Kintsugi for multi-channel sellers who want true automation; Avalara for Fortune 500 companies with complex international needs; Vertex for enterprises with existing ERPs.

When they find you—and they will—you'll owe back taxes, penalties, and interest for every year you weren't compliant. Why can't my accountant handle sales tax compliance? They can file returns, but can they track nexus across 45 states? Calculate rates for 13,000 jurisdictions? Manage exemption certificates? Most CPAs refer sales tax compliance to specialists—like us.
