Sales tax compliance requires businesses to follow a complete process which starts with nexus determination and continues through taxable sales tracking and correct tax collection and timely filing of sales tax returns and payments to all relevant tax authorities including state and local and international jurisdictions. Traditional retailers operate under straightforward geographic rules but e-commerce businesses and technology companies must navigate through complex marketplace and SaaS and multi-state regulatory systems. Sales tax compliance software automates the process of rate calculation and reporting and remittance while sales tax compliance services provide specialized monitoring for complex situations and tax exemptions and audit support.
