When must a marketplace perform KYC on sellers and buyers?

Most marketplaces must KYC sellers who receive payouts and screen all parties for sanctions. Buyers are typically screened for sanctions, with identity checks required in higher‑risk cases (e.g., age‑restricted goods, high‑value items, regulated services) or by provider policy.

How often should we refresh KYC and re‑screen for sanctions?

Screen sanctions at onboarding and on an ongoing basis (often daily via your provider). Refresh KYC using a risk‑based cadence—12 to 36 months is common—plus on trigger events like ownership changes, anomalous activity, or regulator requests.

Do we need a money transmitter or payment license?

If you control or hold customer funds, you may need licensing (e.g., money transmission). Many marketplaces avoid this by using a licensed payment service provider that performs split payouts or escrow. Requirements are jurisdiction‑specific—consult qualified counsel.

What taxes are marketplaces responsible for collecting?

In many U.S. states, marketplace facilitator laws require platforms to collect and remit sales tax on third‑party sales. In the EU, VAT and IOSS rules can make marketplaces the deemed supplier for certain B2C transactions. You may also need to issue compliant invoices and file seller reports (e.g., Form 1099‑K in the U.S.), subject to thresholds.

How should we manage restricted and unsafe products at scale?

Publish clear policies, block high‑risk categories, and require proofs (e.g., certifications, licenses). Use automated signals on titles, images, and attributes; route to trained reviewers; educate sellers; and enforce takedown SLAs with escalating penalties for repeat violations.

What is a compliant IP takedown process for marketplaces?

Provide a clear mechanism to submit notices, verify completeness, promptly remove or disable listings, notify the seller, and allow counter‑notices where applicable. Keep repeat‑infringer policies, preserve evidence, and track resolution times and outcomes.

How does PSD2 Strong Customer Authentication affect checkout?

In the EU/UK, many electronic payments require SCA. Work with your PSP to support 3DS2, apply permitted exemptions (e.g., low‑value, TRA, MIT), and handle step‑ups and soft declines gracefully. Ensure seller‑initiated and marketplace‑initiated flows are mapped correctly.

Which records should we retain to be audit‑ready?

Maintain KYC files, sanctions screening results, approvals and review logs, payment and payout records, tax collection and remittance data, complaint and dispute tickets, takedown actions, and training attestations. Set retention periods per law—often 5–10 years—and secure storage.

Marketplace Compliance: KYC/AML, Product Safety, Taxes & Policy

Jump to section

Overview

Marketplace compliance is the practical layer that keeps risk low and trust high—aligning regulations, platform rules, and day‑to‑day operations across onboarding, listings, payments, fulfillment, and support.

This category covers the core stack: KYC/AML and sanctions screening, product and content governance, payments and tax obligations, privacy and data retention, incident response, and audit readiness. Expect pragmatic guidance over theory.

Use these guides to design policies, standardize reviews, automate where safe, and measure outcomes. The goal is clear ownership, defensible decisions, and friction that’s proportionate to risk.

Key Takeaways

Actionable points curated for this category.

Map the compliance surface

Diagram how users, listings, money, and data flow across onboarding, listing, checkout, fulfillment, and returns. Tie concrete legal and platform obligations to each step by region and category.

Apply risk‑based KYC/AML and sanctions screening

Verify sellers receiving payouts and screen all parties against sanctions lists. Collect IDs, business registration, and beneficial owners as needed; refresh and re‑screen on a risk‑based schedule and on trigger events.

Govern products, content, and IP

Define restricted items, require documentation (e.g., safety certificates), and enforce age gates. Combine automated detection with expert review, and run a fast, fair IP takedown process with repeat‑infringer controls.

Get payments and tax right

Use a licensed payments provider, follow PCI DSS, and support PSD2 SCA where required. Understand marketplace facilitator rules, VAT/IOSS, and seller information reporting; issue compliant invoices and receipts.

Protect data and prove compliance

Meet GDPR/CCPA obligations, sign DPAs with vendors, minimize data, and set retention schedules. Maintain audit trails, approval logs, and breach‑response playbooks to evidence decisions and timing.

Operationalize and measure

Publish policies, playbooks, and SLAs; train reviewers; and sample for quality. Track time‑to‑approve, false positive rate, takedown SLAs, chargebacks, and loss—then iterate controls based on trends.
