Bottom line

For China brands, Amazon FBA is a marketplace plus fulfillment system—it does not replace U.S. tax compliance. Inventory in Amazon’s U.S. network can create sales-tax physical nexus; payouts implicate income tax and information reporting; many sellers also need a U.S. entity, an EIN, books, and the correct federal forms (1120 / 5472 paths, among others). Treat FBA as three layers: (1) platform operations and settlement reporting; (2) sales tax (facilitator collection ≠ zero seller duty); (3) federal/state income tax and entity maintenance. This article is a seller compliance-planning map—not a promise of an “optimal” result or penalty relief.

Background

Many China brands reach U.S. Prime customers through FBA. Pain points that circulate on social channels—“three years of sales before the first accountant,” “Amazon collects sales tax so we’re done,” “we formed an LLC and never heard of 5472,” “treat settlements as profit,” “duties paid equals U.S. tax done”—should be reframed in website language as executable compliance layers: entity and EIN, settlements-to-ledger, sales-tax matrix, income-tax path, and information-return calendar. Amazon is a channel; the IRS and state tax agencies still care about classification, nexus, and support. Cary / RTP seller teams often also run Shopify or wholesale—hybrid models need one compliance spine, not unrelated spreadsheets. Use this as a written checklist before a Free Consultation.

What changed / options compared

High-level only; fees, 1099-K thresholds, and state rules 待核.

1. Business structure

- China-only company vs U.S. LLC/C-Corp subsidiary vs hybrid.

- Banking/payout KYC often pushes a U.S. entity + EIN—formation ≠ compliance finished.

- Foreign-owned single-member disregarded LLC: calendar Form 5472 + pro forma 1120 even when activity is thin.

2. Bookkeeping aligned to Seller Central

- Map settlement / date-range reports to revenue, referral fees, FBA fees, ads (AMS), refunds, reimbursements, and inventory changes.

- Landed cost (product + international freight + duties + first-mile) into COGS—do not expense all replenishment.

- Separate owner draws/loans from operating expenses; avoid paying China factories from U.S. Amazon proceeds with no contract/invoice.

3. Sales-tax layer

- Marketplace facilitator: in applicable states, Amazon often collects and remits on facilitated U.S. store orders.

- FBA inventory placement can still trigger physical-nexus registration analysis.

- Non-Amazon channels (DTC, wholesale, offline) remain on the seller—build a separate matrix (see the sales-tax nexus article).

4. Income-tax layer

- U.S. C-Corp: generally Form 1120.

- Disregarded / foreign owners: residency, ECI, withholding, and treaty issues are fact-specific (待核)—do not copy a peer’s return.

- State income/franchise tax may follow payroll, inventory, or sales factors different from sales-tax rules.

5. Platform and IRS information reporting

- Third-party settlement reporting (often discussed as Form 1099-K) has changed in recent years—待核 your tax-year rules and what Amazon actually issues.

- Tie 1099-K (or equivalent) to the ledger; separate gross proceeds from fees to avoid underreporting or double counting.

6. Import duties vs income tax vs common pitfalls

- Duties, Section 301–related charges, and broker bills are not income-tax or sales-tax returns—budget both stacks.

- Common pitfalls: chasing ad ROI with no books; mixing personal payouts; ignoring state annual/franchise filings; treating facilitator collection as “all states finished”; multi-year 5472 gaps.

Self-check: are you affected?

1. You are a China brand with multi-state FBA inventory but only personal China accounts or mixed payout history.

2. You rely on “Amazon collects sales tax” while also running Shopify/wholesale—without channel splits.

3. You have a foreign-owned single-member U.S. LLC with FBA revenue and have never evaluated 5472.

4. You treat Amazon deposits as “profit” without fee, inventory, and COGS accruals.

5. You pay China factories from U.S. Amazon proceeds without contracts, invoices, or intercompany support.

6. You skip state franchise/annual reports because “we only sell on Amazon”—entity upkeep ≠ Seller Central.

7. You have never tied 1099-K / settlements to the general ledger and only export at tax season.

Simplified example (illustrative only)

Example A — U.S. LLC + FBA-only

Ms. Zhou’s Shanghai brand wholly owns a U.S. LLC (disregarded). FBA sales about $900,000; Amazon fees and ads about $180,000; landed COGS about $420,000. Amazon collects sales tax on many facilitated orders; inventory still spans multiple nodes. She needs monthly books tied to settlements, a 5472 assessment, a sales-tax registration screen beyond facilitator assumptions (待核), and an income-tax path based on classification and U.S. tax status—not a blog template. Tax-bill results are not guaranteed.

Example B — U.S. C-Corp subsidiary

A China parent owns a Delaware C-Corp that receives Amazon payouts and files Form 1120 with clear related-party purchase support. Sales-tax and income-tax workstreams share one calendar, supported by bookkeeping. Structure helps banking and diligence; it does not erase nexus or filing duties.

Example C — “Duties only” misconception

A seller budgets customs duties and first-mile freight as the only U.S. cost, builds no sales-tax matrix, and schedules no federal information/income returns. As fulfillment scales, gaps usually appear in inventory-state registration and annual entity filings together.

Illustrative only; not a case-level tax computation.

Action plan and timeline

1. This week: Download 12–24 months of Amazon date-range and settlement reports; list FBA storage states and SKU categories where possible.

2. Days 1–14: Confirm or form the U.S. entity path; obtain EIN; open a dedicated operating account; freeze a related-party purchases account.

3. Days 14–45: Build settlement-mapped bookkeeping; align intercompany invoice templates with Shanghai finance; put month-end close on the calendar.

4. Within 60 days: Sales-tax nexus screen (FBA + any DTC/wholesale); start registration for flagged states (待核).

5. Quarterly: Revisit income-tax estimates, inventory valuation, ad/fee reconciles, and whether platform collection reports align with seller-filed returns.

6. 90 days before filing season: Lock classification (1120 vs 5472 path, etc.), tie 1099-K/platform reports, decide on Form 7004.

7. Before peak events (Prime Day / BFCM): Recheck inventory placement and sales-tax registration scope so transfers do not stale the matrix.

5. Free Consultation—bring Seller Central exports and formation docs to start compliance planning.

FAQ

Q: Must every FBA seller form a U.S. company?

A: Not as an absolute legal mandate, but payouts, banking, and tax administration often make a U.S. entity practical. Formation also creates filing duties—plan both sides.

Q: Amazon already collects sales tax—are all states finished?

A: Not automatically. Inventory nexus, non-Amazon channels, and registration details remain. Screen state by state.

Q: Will I receive a 1099-K from Amazon?

A: Possibly, depending on the year’s reporting rules and account activity—待核 current thresholds and Amazon’s actual issuance. Whether or not a form arrives, tie platform reports to the books.

Q: Are import duties my only U.S. tax?

A: No. Customs/duties, income tax, sales tax, and information returns are different stacks and need separate budgets.
