Sales Tax Compliance

Sales tax compliance encompasses the end-to-end process of registering for sales tax permits, determining taxability of products and services, calculating the correct tax rate at the point of sale, collecting tax from customers, filing returns, and remitting collected taxes to the appropriate state and local jurisdictions by their respective deadlines. The complexity is staggering: the United States has over 13,000 distinct sales tax jurisdictions with rates ranging from 0% to 11.5% when state, county, city, and special district taxes are combined. Filing frequencies vary by jurisdiction and sales volume — from monthly (for businesses collecting over $300/month in many states) to quarterly or annually for smaller sellers. Post-Wayfair, any e-commerce business exceeding economic nexus thresholds (typically $100,000 in sales or 200 transactions) must comply in each triggered state, potentially requiring registration, collection, and remittance in 20–30+ jurisdictions simultaneously. Non-compliance penalties range from 5–25% of uncollected tax per state, plus interest at 8–12% annually, and personal liability for responsible officers in many states. For a multi-state business with $5 million in annual taxable sales across 15 states, the compliance burden can consume 40–80 hours per month in manual filing effort — equivalent to a half-time employee costing $35,000–$50,000 annually. doola helps businesses automate the entire sales tax compliance lifecycle from nexus monitoring through return filing, while Quadient's invoicing solutions ensure tax amounts are correctly calculated and documented on outbound invoices to support audit defensibility.
