Managing sales tax across multiple states, channels, and tax rules is a growing challenge for modern businesses — especially e-commerce sellers, SaaS platforms, wholesalers, and multi-state operators. With constantly changing laws, marketplace facilitator rules, state-by-state nexus thresholds, and strict deadlines, sales tax isn’t just administrative — it’s a risk area that can lead to penalties, audits, and operational bottlenecks.
At APAKUS, our Sales Tax Management services eliminate complexity and deliver complete compliance confidence.
We handle everything — from nexus discovery and registration to monthly filings, reconciliations, audit representation, and technology setup — so you stay compliant and focused on growth.
Sales tax management includes identifying where your business must collect tax, registering with state agencies, calculating correct rates, filing returns on time, and defending your business in case of audits.
Sales tax is not optional — non-compliance can lead to penalties, interest, back taxes, and legal exposure.
Avoid Penalties & Late Fees
States impose penalties of up to 30% for late or incorrect filings.
Protect Against Audits
Consistent reporting and accurate filings reduce audit risk significantly.
Stay Ahead of Nexus Triggers
Track revenue, transaction count, marketplace sales, and physical presence triggers across 50+ U.S. states.
Eliminate Manual Tax Work
No more rate confusion, manual calculations, or portal logins — we do the heavy lifting.

Sales tax nexus determines whether your business is legally required to collect and remit sales tax in a state. Nexus can be triggered by:
Revenue or transaction thresholds (economic nexus)
Physical presence — employees, offices, warehouses, inventory
Marketplace activity (Amazon, Walmart, Etsy, etc.)
Understanding nexus ensures you don’t face unexpected penalties or retroactive tax bills.
Yes — most e-commerce businesses must collect sales tax based on state-specific economic nexus laws. Even if you don’t have a physical presence, surpassing state sales thresholds (like $100,000 in sales) requires compliance.
We help you determine where, when, and how to collect tax correctly.

Shopify, WooCommerce, BigCommerce
Amazon, Walmart, eBay, Etsy
