Sales Tax Compliance Challenges for US Businesses

Sales tax compliance involves the process which requires businesses to collect sales tax and report their collected amount while sending the tax funds to the right governmental tax offices.

These variations make compliance difficult, especially for growing businesses. Understanding sales tax obligations is the first step toward avoiding errors and penalties.

Sales Tax Audits and Penalty Risks
