## How Sales Tax Applies to Digital Goods -- rate, what's taxable, exemptions, B2B rules

The United States has **no federal VAT/GST** for digital goods. Sales tax is imposed by states (and often local jurisdictions), so the effective rate and taxability can change by customer ZIP code. Some states tax SaaS as tangible-equivalent software access, others exempt many digital downloads, and some tax only specific categories such as streamed media or automated information services. You cannot use one nationwide rule without creating error risk.

The core trigger is usually **economic nexus** after _Wayfair_: once sales or transaction-count thresholds are met in a state, remote sellers must register and collect tax there. B2B treatment also differs by state because exemption certificate rules are state-specific; a business customer is not automatically tax-exempt without valid documentation. For subscription businesses, renewals, seat expansions, and usage overages should inherit the same jurisdiction logic used at first purchase so liability does not drift over time.

## Registration Requirements -- threshold, authority, ID format, timeline

Registration is handled at the **state level** (departments of revenue, taxation commissions, comptrollers), not by a single federal tax authority. Most teams prioritize states where thresholds are already crossed, then expand into near-threshold states based on growth forecasts.

ID formats vary: many states issue seller's permit or sales tax account numbers; some require separate local registrations. A practical rollout is 3-8 weeks for first-wave states if you include nexus analysis, certificate process design, and invoice template updates. Keep a state matrix with threshold type (revenue vs transaction count), filing frequency, due dates, marketplace facilitator interactions, and notice response owner.

## Filing and Compliance -- frequency, authority name, reporting system, retention

Filing cadence ranges from monthly to annual depending on state volume and risk profile. Returns are submitted through each state portal, and some jurisdictions split state tax, county tax, city tax, and special district tax on separate lines. Because rate changes happen frequently, compliance quality depends on date-accurate jurisdiction mapping, not just a static rate table.

Your close process should include per-state taxable sales rollforwards, exemption certificate validity checks, and reconciliation between checkout tax and filed tax. Keep jurisdiction-level reports, exemption certificates, resale documentation, return confirmations, payment proofs, and adjustment notes in an audit-ready archive. If prior-period corrections are required, document whether the change came from nexus onset, product taxability reclassification, or missing exemption evidence.
